Abstract: Apparatus for reprogramming a programmed controller of a power driven wheelchair comprises:a reprogrammable, non-volatile memory programmed with a plurality of programs executable by the controller to operate the wheelchair, the non-volatile memory disposed at the wheelchair and coupled to the wheelchair controller; a general-purpose computer programmed to reprogram the non-volatile memory while disposed at the wheelchair, the programmed computer for storing main programs for use in reprogramming the non-volatile memory, the programmed computer being coupleable to the wheelchair controller for accommodating an exchange of data therebetween; and wherein the wheelchair controller being operative to communicate with the programmed computer to reprogram the non-volatile memory with the main programs while the non-volatile memory is disposed at the wheelchair. Methods for reprogramming the non-volatile memory are also disclosed.

Abstract: A drive motor assembly for a power driven wheelchair comprises: a stator housing for containing field coils of a stator of the motor assembly; at least one sensor disposed in the stator housing for sensing rotation of the motor; a memory storing motor error parameter data including data of errors of the at least one sensor, the memory being embedded in the stator housing; and a connection for accessing the error parameter data of the memory from the stator housing. The motor error parameter data may be accessed from the embedded memory of the drive motor by a programmed motor controller for use in controlling the drive motor.

Abstract: A method of setting values of a multiplicity of performance parameters of a power driven wheelchair into a controller thereof for use by the controller in the operation of the wheelchair by a user comprises the steps of: grouping the multiplicity of performance parameters of the wheelchair into at least two groups, each group including more than one performance parameter; for each group, (a) establishing a corresponding relationship between a selected performance parameter of the group and each of the other performance parameters of the group; and (b) presetting the established relationships into the controller of the wheelchair; determining a value for the selected performance parameter of each group based on the user's capabilities of operating the wheelchair; entering the determined value for the selected performance parameter of each group into the controller; deriving automatically by the controller for each group a value for each of the other performance parameters of the group based on the entered valu

Abstract: A rigid appendage fastening means that may be adapted to mount an apparatus that is commonly possessed and carried by law enforcement officers, military personnel and civilians, who are licensed to do so, diurnally. The appendage fastening means is specifically designed to be mounted to those items that the user intends to keep hidden from the view of a casual observer. The device's primary design characteristic is that of a loosely formed sigmate. The principal object is camouflaged to suit the user's apparel, thereby enhancing the device's covert characteristics and applications. The device provides the user with a secure environment to place an item inside the waistband (IWB) and below the belt line (BBL). Objects of appropriate size and utility, which have the principal object mounted to them, can be secreted upon the user's person IWB. Said object remains IWB, BBL with Total Concealment (TC), easily accessible, safe, secure, and immediately available for use.

Abstract: A concentrically shaped, moisture and dust resistant apparatus for storing tools and roadside emergency equipment. The device is designed to remain in a suspended state between the wheel of a spare tire and the underside of a motor vehicle. It is positioned above the spare tire on the metal portion of the wheel and is held in place by means of a factory installed winch system. The principal object has two separate, semi-circular compartments which, when joined, form a spherically shaped apparatus. An inner circular opening located at the mid-point of the principal object allows a spare tire retention cable and its fastening means to be received and passed through it. The arcuate exterior has positioned upon it three essentially flat and level surface segments: one at 180 degrees at the bottom of the device and two on adjacent, but opposite sides of the principal object, at 90 and 270 degrees, respectively.
