Abstract: A flexible, low friction, rideable sliding toy is disclosed that slides over relatively smooth, firm surfaces with very low friction. The toy is comprised of a bag of flexible, air impermeable material having one or more relatively large holes cut out of the bottom of the bag where the bag contacts the floor when in use. The bag is inflated by allowing it to drop onto the floor, trapping air inside it as it lands. The outer edges of the hole form a relatively airtight seal allowing the bag to retain its inflated state when laid upon by a user, thus permitting a user to propel himself over fiat surfaces in a low friction manner. A flap of material may be affixed inside the bag positioned so that it lies loosely over the large holes, providing a seal when the bag leaks unduly.
Abstract: An improved human powered recumbent vehicle is provided. The vehicle includes a frame that comprises a central keel. The keel comprises four tubes that are spaced equidistant from a central longitudinal axis. Outrigger arms are disposed approximately halfway along the longitudinal axis of the keel and extend forwardly and outwardly therefrom. The angle that each outrigger arm forms with the keel, provides an access area that allows a rider access to the seat without having to step over any portion of the invented vehicle, for easy mounting and dismounting. Outboard ends of the arms terminate in pivotable connectors that may be provided for wheel bearing yokes. A rear section of the keel is wide enough to accommodate a wheel. The keel has a prow that terminates in a single plane, so that the vehicle can be placed on its prow for storage in an upright position, to minimize storage space.

Abstract: An integrated controller for a vehicle comprises a contact preventive device for detecting a distance between a vehicle and an obstacle and a relative speed, and deciding whether the vehicle may come in contact with the obstacle based on the results of detection so as to perform automatic braking or automatic steering, and a characteristic changing device for causing the suspension or steering characteristic of the vehicle to be changed. The control part of the characteristic changing device changes the suspension or steering characteristic based on information from the control part of the contact preventive device when operating the contact preventive device. In case the characteristic changing device is an active suspension device, the control part changes the suspension characteristic so as to increase a control gain when performing automatic braking and to inhibit the vehicle from being rolled when performing automatic steering.

Abstract: Apparatus and method for controlling an occupant restraint system in a vehicle (10) comprises storing in a ROM memory (220) a block of image data representative of a viewing field within the vehicle (10). The viewing field includes an unoccupied vehicle seat (18) located in the occupant compartment (12) of the vehicle. A new block of image data is obtained which is representative of the viewing field with an occupant (202) on the seat (18). This image data is obtained with an image sensor (200), such as a CCD sensor, mounted in the vehicle (10) for viewing the field. The new block of image data is compared with the stored block of image data by a controller (30) to obtain the occupant's size and/or position in the vehicle. The controller (30) provides a control signal having a value which is a function of the comparison. A restraint regulator (120), such as a vent valve, responds to the control signal for controlling the occupant restraint system.

Abstract: All improvement in a kit for converting a motorcycle to a tricycle is described. The kit includes a pair of swing arms having a first end and a second end. Axle couplings are provided at the first end of each swing arm whereby the swing arms are secured to an axle which supports two wheels. Pin receiving couplings are provided at the second end of each swing arm whereby the swing arms are pivotally secured by pins to a motorcycle frame. The improvement is characterized by swing arms having a top surface and a bottom surface. The axle coupling and the pin receiving coupling extend vertically from the top surface of the swing arms. The top positioning of the axle couplings and the pin receiving couplings leaves the majority of the top surface of the swing arms dropped below the level of the original floor boards of the motorcycle. The swing arms can pivot as intended without their movement being impeded by the original floor boards.
