Obstacle avoidance for power wheelchair using bayesian neural network.

In this paper we present a real-time obstacle avoidance algorithm using a Bayesian neural network for a laser based medicare power wheelchairs system. The raw laser data is modified to accommodate the wheelchair dimensions, allowing the free-space to be determined accurately in real-time. Data acquisition is performed to collect the patterns required for training the neural network. A Bayesian frame work is applied to determine the optimal neural network structure for the training data. This neural network is trained under the supervision of the Bayesian rule and handicap scooters the obstacle avoidance task is then implemented for the wheelchair system. Initial results suggest this approach provides an effective solution for autonomous tasks, suggesting Bayesian neural networks may be useful for wider assistive technology applications

The easiest way to achieve this when you have a bad business line of credit card is to leave the card at home. If you really need the purchase, you can go back to the store the next day. This will give you time to think about whether you really need to buy those new shoes or could you get by without them?

Design features of portable wheelchair ramps and their implications for curb and vehicle access.

This study evaluated a range of portable wheelchair ramps to highlight the effect of different product features on ease of use when power wheelchairs
And medicare power wheelchairs users climb curbs or access vehicles. Twelve portable ramps were evaluated. Although all the ramps were designed to load powered wheelchairs into motor vehicles, they were manufactured in different designs. The ramps were based on a “singlewide” platform or “channel” design. Some ramps had fixed dimensions, whereas others could be reduced in size because they were telescopic or designed to allow folding. Overall, the ramps could be divided into four subgroups on the basis of their key features. These were horizontally and longitudinally folding ramps, telescopic ramps, and ramps with fixed dimensions. The telescopic ramps could be subdivided into “U”-shaped gutter ramps and reverse profile ramps. Product appraisals and trials involving wheelchair users and caregivers of wheelchair users were done to evaluate each of these ramp designs. Although wheelchair ramps are available in a wide range of designs and configurations, we found that no single ramp design successfully met the needs of all wheelchair users or their caregivers. The evaluation highlighted a number of specific problems and potential hazards. Some ramps were found to move during a maneuver, showed poor stability when used with some vehicles, or were too narrow to allow wheelchair castors to pass through the channel without jamming. Some features, such as handles and locking mechanisms, influenced the ease with which the caregivers could use the ramps. Wheelchair users preferred the wide platform ramps because they were able to drive up these with ease and little preparation. The caregivers preferred folding or telescopic channel ramps because these were easier to handle and store.

Watch for Hidden Fees

Many solicitations, especially through the mail, promise universal acceptance, pre-approval and high business line of credit limits. Always read the fine print for fees and hidden charges. Deals that sound too good usually are. If the responsible and savvy consumer can successfully compare building business credit cards and their interest rates and charges, it is possible to move balances to more favorable cards by combining balances and juggling finances. These options are best used for those with higher credit lines, and with the advice of a tax accountant or bookkeeper.

Physical capacity in wheelchair-dependent persons with a spinal cord injury: a critical review of the literature

STUDY DESIGN: Review of publications. OBJECTIVE: To assess the level of physical capacity (peak oxygen uptake, medical scooters peak power output, muscle strength of the upper extremity and respiratory function) in wheelchair-dependent persons with a spinal cord injury (SCI). SETTING: Erasmus MC, University Medical Centre Rotterdam, The Netherlands. METHODS: Pubmed (Medline) search of publications from 1980 onwards. Studies were systematically assessed. Weighted means were calculated for baseline values. RESULTS: In tetraplegia, the weighted mean for peak oxygen uptake was 0.89 l/min for the wheelchair exercise test (WCE) and 0.87 l/min for arm-cranking or hand-cycling (ACE). The peak power output was 26 W (WCE) and 40 W (ACE). In paraplegia, the peak oxygen uptake was 2.10 l/min (WCE) and 1.51 l/min (ACE), whereas the peak power output was 74 W (ACE) and 85 W (WCE). In paraplegia, muscle strength of the upper extremity and respiratory function were comparable to that in the able-bodied population. In tetraplegia muscle strength varied greatly, and respiratory function was reduced to 55-59% of the predicted values for an age-, gender- and height-matched able-bodied population. CONCLUSIONS: Physical capacity is reduced and varies in SCI. The variation between results is caused by population and methodological differences. Standardized measurement of physical capacity is needed to further develop comparative values for clinical practice and rehabilitation research
