A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The motor is drivingly connected to the first arm such that a rotation of the motor causes rotation of the first arm about its first end and moves the stepping member from a retracted position to an extended position, or vice versa. The stop is located within the range of motion of the second arm such that the second arm bears against the stop when the stepping member is in the extended position. The first and second arms are situated such that the first arm is loaded in compression and the second arm is loaded in tension when the stepping member is in the extended position and a load is placed upon it.

A blind spot detector system adapted to the exterior of a vehicle comprising at least one infrared light emitting diode (LED), an infrared photodetector and demodulator, and a microcontroller. The output power of the infrared transmitter is linearly modulated, enabling the blind spot detector to determine the proximity of the detected object. Furthermore, the transmitter output is frequency modulated to screen out random infrared radiation that might adversely affect the operation of the infrared photodetector. The system is calibrated to the position of the attached vehicle by linearly increasing the output power of the transmitter until the rear quadrant of the vehicle is detected when the transmitter is outputting power at a pre-determined calibration level. During normal operation, an object detected while the transmitted power is greater than a predetermined lower threshold and less than the calibration level will activate a LED indicator on the system housing.

A sequentially or serial inflating seat cushion comprising at least three transversely aligned inflatable air bladders connected to a pump and timer. The air bladders are inflated sequentially, from front to back, over a period of approximately eleven seconds and simultaneously deflated to slowly pump blood upward in the legs thereby reducing blood pooling. Connected to the pump is a valve that keeps the air bladders inflated a selective amount of time. The cycle is then repeated continuously. Located adjacent to the back air bladder is a transversely aligned, non-inflating seat section which continuously supports the user's ischial tuberocities to prevent slippage over the seat. An alternate embodiment offers a split seat option with six inflatable bladders.
