Improvement of angular velocity and position estimation in gyro‐free inertial navigation based on vision aid equipment

In conventional navigation systems, inertial sensors consist of accelerometers and gyroscopes. These sensors suffer from in‐built errors, accumulated drift and high‐level noise sensitivity. The accurate gyroscopes are expensive and not suitable in cost‐effective applications. To minimise such disadvantages, one solution is the combination of inertial sensors with different aiding sensors. To lower the cost, utilisation of redundant accelerometer structure as gyro‐free inertial measurement unit (GFIMU) has been proposed. In this study, Gyro‐Free navigation errors using four tri‐axial accelerometers are illustrated. Compensation of errors in terms of angular velocity and position estimation is verified based on adding a simple gyroscope, inexpensive stereo cameras as well as creating an easy to use topological map. The topological map is easily created by means of scale‐invariant feature transform method. The estimation of angular velocity is corrected on the basis of fusing the measurements from GFIMU and a simple gyroscope using unscented Kalman filter. The correction of position is performed by comparing the estimated position from GFIMU and observation of stereo cameras together with topological map. The results of the research show that the collaboration of GFIMU, stereo cameras and simple gyroscope will improve the robustness and accuracy of navigation, significantly.

The South Dakota Model: Health Care Professions Student Disaster Preparedness and Deployment Training.

The Association of American Medical Colleges recommended an increase in medical education for public health emergencies, bioterrorism, and weapons of mass destruction in 2003. The University of South Dakota Sanford School of Medicine (USD SSOM) implemented a 1-day training event to provide disaster preparedness training and deployment organization for health professions students called Disaster Training Day (DTD). Hospital staff and emergency medical services personnel provided the lecture portion of DTD using Core Disaster Life Support (CDLS; National Disaster Life Support Foundation) as the framework. Pre-test and post-test analyses were presented to the students. Small group activities covered leadership, anaphylaxis, mass fatality, points of dispensing deployment training, psychological first aid, triage, and personal protective equipment. Students were given the option to sign up for statewide deployment through the South Dakota Statewide Emergency Registry of Volunteers (SERV SD). DTD data and student satisfaction surveys from 2009 to 2016 were reviewed. Since 2004, DTD has provided disaster preparedness training to 2246 students across 13 health professions. Significant improvement was shown on CDLS post-test performance with a t-score of -14.24 and a resulting P value of <0.00001. Students showed high levels of satisfaction on a 5-level Likert scale with overall training, small group sessions, and perceived self-competency relating to disaster response. SERV SD registration increased in 2015, and 77.5% of the participants registered in 2016. DTD at the USD SSOM provides for an effective 1-day disaster training course for health professions students. Resources from around the state were coordinated to provide training, liability coverage, and deployment organization for hundreds of students representing multiple health professions.

福祉機器のヒューマンインタフェース

In the welfare field, human interface plays an important role in connecting the user with the welfare support equipment. As this kind of interface has the effect of improving the QOL(Quality of Life) of the hospitalized inpatients and home care patients, many interfaces for assistive devices using image processing and sensors have been developed. Especially for patients with neurological disorders, an interface for communication is essential due to the limitation of the movable body parts. This paper aims to present a brief review of some developed interfaces, focusing on the operation of the electric wheelchair, the communication aid equipment, and an example of our experimental research using gazing actions.

Medical Pathologies and Hut Guardians’ Ability to Provide First Aid in Mountain Huts: A Prospective Observational Study

To describe the resources for medical condition management in mountain huts and the epidemiology of such events. We conducted a 3-step study from April 2013 to August 2014 in French mountain huts. The first step consisted of collecting data regarding the first aid equipment available in mountain huts. The second step consisted of a qualitative evaluation of the mountain hut guardian's role in medical situations through semistructured interviews. Finally, a prospective observational study was conducted in the summer season to collect all medical events (MEs) that occurred during that period. Out of 164 hut guardians, 141 (86%) had a basic life support diploma. An automatic external defibrillator was available in 41 (26%) huts, and 148 huts (98%) were equipped with a first aid kit. According to semistructured interviews, hut guardians played a valuable role in first aid assistance. Regarding the observational study, 306 people requested the hut guardian's help for medical reasons in 87 of the 126 huts included. A total of 501 MEs for approximately 56,000 hikers (0.85%) were reported, with 280 MEs (56%) involving medical pathologies and 221 (44%) MEs involving trauma-related injuries. MEs had low prevalence, but the hut guardian played a valuable role as a first aid responder.

Historical Review: The U.S. Army Medical Belt for Front Line First Aid: A Well-Considered Design That Failed the Medical Department During the First World War.

In December 1913, a board of medical officers was appointed to adapt new U.S. Army equipment to the needs of the Hospital Corps. One of the improvements concerned substitution of the satchel-like Hospital Corps pouch used to carry first aid equipment. A waist belt with 10 pockets, known as the medical belt, was devised, and supplied with a tourniquet, adhesive plaster, safety pins, iodine swabs, sublimated gauze, individual dressing packets, gauze bandages, aromatic spirit of ammonia, and common pins. In addition, an ax carrier accommodating a hand ax, a canteen hanger, and a pouch to carry diagnosis tags and instruments were attached to the medical belt. In 1916, the medical belt was incorporated in the field supply tables in the Manual for the Medical Department. The next year, on April 6, 1917, the U.S. Congress declared war on Germany in reaction to sinking of American ships by German submarines. Although the medical belt had given satisfaction in preliminary trials, it did not withstand the test of war. In practice, the medical belt proved a source of dissatisfaction both as to the methods of packing and its contents, which were considered useless in modern warfare. Subsequently, discontinuance of the medical belt was recommended.

Operation Strategy Development for Grignard Reaction in a Continuous Stirred Tank Reactor

This paper presents a case study in establishing the operation space of a Grignard reaction in a continuous stirred tank reactor (CSTR). The operation space is the multivariate space with the boundary defined by the proven acceptable range of every CSTR process parameter such as flow rates and temperature. The mapping of the operation space was conducted by a thorough understanding of reaction kinetics, magnesium (Mg) sequestration efficiency, equipment characterization, and the impact of process disturbances has on steady state. A fit-for-use reaction kinetics model was developed to parametrize the kinetics and mass transfer rates of the batch Grignard reaction across different scales from 250 mL to 500 gallons. The reaction kinetics model was applied to design the Mg recharge frequency accounting operational variability to ensure a state of control can be maintained. Furthermore, reactor temperature was determined to be suitable to detect process failures to ensure process safety and product quality at manufacturing scale. Computational fluid dynamics (CFD) models were also applied to aid equipment design to maximize Mg sequestration in the CSTR. Based on the optimal equipment design, the unit operation was scaled-down to test the sequestration efficiency. The resulting process understanding enabled the team to define the final operation strategy to ensure a safe and robust commercial process.

Influence of Sawmill Industries on the Health of Sawmill Workers and Inhabitant of the Environment in Ondo State Nigeria

This study examined the influence of sawmill wastes on health among the sawmill workers and inhabitants of the environment in Ondo State Nigeria. A total of 240 respondents consisting of 110 sawmill workers and 130 inhabitants of residential areas around sawmills were drawn using accidental sampling technique. A validated self-structured questionnaire with reliability coefficient of 0.85 was used for the study. The data collected were analyzed using simple percentages and inferential statistics of t-test analysis. The findings of the study revealed that the respondents did not have knowledge and experience about the importance of health education, the safety gadgets, protective devices and environmental health aids equipment were not adequate, there was a significant difference in the awareness of wastes generated in the sawmills between the sawmill workers and the inhabitant of the residential areas, a significant difference in the awareness of diseases contracted in sawmills that can affect health, and a significant difference in the excessive exposure to loud noise. It is therefore recommended that wastes should not be burnt. Sawmills operators should be provided with protective shield and gloves, and be monitored to wear them regularly. First aid box and toilets should be provided. DOI: 10.5901/jesr.2015.v5n2p299

Equipment, Risk Awareness and Safety-Relevant Behaviour of Via Ferrata Climbers

Climbing via ferrata routes is becoming more and more popular. The growing number of via ferrata climbers is associated with an increasing number of accidents. In addition to adequate equipment and its correct handling, knowledge of specific risks and safety-related behaviour play an important role for safety on via ferrata routes. The goal of this study was to collect data on equipment, via ferrata-specific risk knowledge, safety-related behaviour, and general risk-taking behaviour of via ferrata climbers. In this survey, data of 332 climbers of different via ferrata routes in Tyrol (Austria) were collected using a standardised data entry form including socio-demographic data, the use of via ferrata-specific equipment and first aid equipment. Knowledge of via ferrata-specific risks was assayed by a questionnaire including 4 questions. Additionally, safety-related behaviour and general risk-taking behaviour of the via ferrata climbers were evaluated. 92 % of the interviewed persons were wearing a helmet and helmet use was significantly lower in females (86 %) compared to males (96 %). In total, 10 % of the via ferrata climbers used inadequate belaying equipment or no equipment at all. The 4 questions related to via ferrata-specific risks were correctly answered by an average of 46 % of the climbers. A partner check was carried out by 76 % before starting the tour. 96 % of the climbers stated they ask the climber ahead of them for the possibility to overtake and wait for a suitable and safe spot. 64 % reported that they would not pass without self-belay. General risk-taking behaviour was scored at 4.26 ± 1.75 with significant differences between female and male via ferrata climbers (3.79 ± 1.37 vs. 4.53 ± 1.88). Although most of the via ferrata climbers use adequate equipment, helmet use could be optimised in females. Via ferrata climbers should be better informed of the risks of climbing via ferrata routes and safety-related behaviour. Preventive measures including information panels at the entrances of the via ferrata routes and broad information campaigns could contribute to reduce the number of accidents.

Awareness, attitudes and practices of first aid among school teachers in Mangalore, south India.

Circumstances requiring medical attention are common at schools. Teachers are often the first individuals to witness and handle situations requiring first aid and medical emergencies. To determine awareness, attitudes and practices of school teachers and the facilities available at schools with respect to administration of first aid. Data were obtained from 146 teachers in nine schools in Mangalore, India, using a self-administered questionnaire. The schools were also inspected for first aid equipment and facilities. Only 69 (47%) teachers had received first aid training previously. Poor and moderate knowledge of first aid was observed among 19 (13%) and 127 (87%) teachers, respectively. Only eight teachers knew the correct procedure for cardiopulmonary resuscitation. Most teachers 96 (66%) were willing to administer first aid if provided with the required training. A total of 74 teachers reported having practised first aid in response to a situation arising at their school. Wounds (36%) and syncopal attack (23%) were among the commonly encountered situations requiring first aid management at schools. Teachers' confidence level in administering first aid was significantly associated with prior training in first aid (p=0.001). First aid kits were available in only five of the nine schools surveyed. The current competency level among teachers in Mangalore to administer first aid is inadequate. Measures need to be taken at schools to ensure initiation of first aid training followed by periodic training for teachers in first aid.

What are we putting in our ears? A consumer product analysis of aural foreign bodies.

Rapid identification of foreign bodies may be crucial in deciding the appropriate course of action; and knowledge of consumer products that most commonly become aural foreign bodies (AFB) may potentially guide patient education strategies. Our objectives were to estimate the nationwide incidence of emergency department (ED) visits for consumer products presenting as AFBs and describe products encountered, demographic trends, general outcomes, and other reported aspects of injury. The authors searched the National Electronic Injury Surveillance System for AFB ED visits from 2008 to 2012. Consumer product, patient demographics, and outcomes were analyzed. There were 9,472 case entries amounting to an estimated 280,939 ED visits for AFBs. Of these, 49.3% of patients were male and 50.7% were female, with 98.2% of all patients being treated/examined and then released. Jewelry was the most common foreign body (39.4%), followed by cotton swabs/first aid equipment, paper products, pens/pencils, and desk supplies. Children between 2 and 8 years of age were most commonly affected, with jewelry as the most common item. Cotton swabs/first aid equipment predominated among adults. Aural foreign bodies considerably affect health care expenditures; over 250,000 ED visits over a 5-year span were noted. Age- and gender-specific patterns reported in this analysis can serve as a valuable adjunct for history taking and clinical examination. Jewelry products predominated among children, while cotton swab/first aid products, hearing aids, and other ear-specific accessories significantly affected adults. Although children were most commonly affected, these findings highlight the need for sustained education and prevention strategies among all age groups.

Anodic Protection of Carbon Steel AISI 1006 Using the Binder of Undoped Polyaniline

The use of intrinsically conductive polymers such as polyaniline (PAni) has been presented as an alternative protective coating against corrosion, it intensifies the effect of anodic passivation and protection of the material. Given the difficulty in obtaining films of polyaniline in the oxidized form and driver in a self-supported and cohesive on the surface of metal substrates. Was held the undoped of the polymer, with the use of NH4OH solution to passing the PAni oxidized state and non-conducting polyaniline emeraldine base known as PAni EB. The complete mixture of PAni EB, organic solvent and plasticizer 4-chloro-3-methylphenol, allowed to obtain a resin. This was applied in AISI 1006 steel plates with the aid equipment Spin Coater. The film was characterized by thermal analysis TGA, where it was found that the coating is the result of the reaction components, predominantly the structure of PAni EB. The electrochemical tests of Cyclic Voltammetry and Potential Open Circuit were carried out in 2 molL-1H2SO4solution, which indicated the formation of redox couple polymer-metal, which provides the formation of passivating oxides, which allow the metal anodic protection against corrosion.

Increasing schools' access to automated external defibrillators

Every year, children and young people die in cases of sudden cardiac arrest. Early CPR and defibrillation can help save lives. The Government has recently recommended that schools should consider purchasing a defibrillator as part of their first aid equipment.

Acoustic Source Localization via Subspace Based Method Using Small Aperture MEMS Arrays

Small aperture microphone arrays provide many advantages for portable devices and hearing aid equipment. In this paper, a subspace based localization method is proposed for acoustic source using small aperture arrays. The effects of array aperture on localization are analyzed by using array response (array manifold). Besides array aperture, the frequency of acoustic source and the variance of signal power are simulated to demonstrate how to optimize localization performance, which is carried out by introducing frequency error with the proposed method. The proposed method for 5 mm array aperture is validated by simulations and experiments with MEMS microphone arrays. Different types of acoustic sources can be localized with the highest precision of 6 degrees even in the presence of wind noise and other noises. Furthermore, the proposed method reduces the computational complexity compared with other methods.

Surf, sand, scrapes and stings: First aid incidents involving children at New Zealand beaches, 2007–2012.

Aims: In spite of the popularity of beaches for family recreation, little is known about childhood injuries sustained at beaches. It is the purpose of this study to analyse data from incidents necessitating first aid treatment from reports compiled by surf lifeguards on New Zealand beaches.Method: A retrospective analysis of first aid incidents involving children (<16 years) was conducted using data obtained from Surf Life Saving New Zealand incident report forms during five summer seasons from 2007 to 2012. In addition to demographic data, the incident reports included such detail as the type of injury, the activity and location prior to injury, the injury outcome, and the first aid equipment used.Results: Children (n = 4407) accounted for one-half (52%) of all injuries; of these, 55% were male, and incidence peaked in the 11- to 15-year age group (24%). Most incidents (90%) required minor treatment, with lacerations (44%) the most common injury. Marine stings accounted for one-quarter (24%) of injuries and were most frequent among younger children (<10 years). Injuries to the extremities were frequently noted in the incident reports, the feet (33%) and hands (8%) being common sites.Conclusions: Although most (90%) injury incidents were minor in nature, their frequency (880 cases per season) suggests that greater emphasis on prevention rather than cure would be efficacious. Ways of promoting child beach safety via greater care giver awareness, the use of protective clothing and footwear, and child safety promotion via health professionals and safety organisations are discussed.

Anticipating needs and designing new items rapidly - a case study for the design of postural aid equipment

In this case study, designers proactively proposed new product ideas to a client by using an ergonomic approach. This approach differs from a more traditional approach where one works within a specific, clientdefined project. The methodology used included basic ergonomic techniques such as task analysis and information gathering sessions conducted with users. It was adapted so that these enriched user sessions could be conducted within a short time period. After meeting with five users in seven days, designers identified 20 problems that could be tackled and eight design ideas that could be implemented over the short, medium and long term. The ideas encompassed a wide range of potential projects, including physical product improvements, new product lines, Web-site and software improvements and longer term research. Problems identified and ideas generated involved many disciplines including occupational therapy, mechanical engineering, graphical design, software engineering, sales and manufacturing know-how. This wide range was possible because designers were not constrained to specific project scopes and timelines. The client was involved in the idea evaluation process. As a result of this study two new projects were initiated so far.
