Abstract: An improved six degree of freedom computer mouse-like input device for intuitively manipulating a mouse pointer through three-dimension space. The device allows a human operator to more closely complement the operator's natural hand range of motion through a bounded input volume in order to interact with three-dimensional computer software programs.

Abstract: A vehicle impact sensor arrangement is provided for sensing a side impact. The arrangement comprises at least one sensor which is directly or indirectly fixed to the monocoque shell of a motor vehicle and which is responsive to inward movement of part of a door mounted on a motor vehicle. The part of the door adjacent the sensor is reinforced.

Abstract: An apparatus automatically sets a specific number for video equipment corresponding to a cable box which is connected to the video equipment. The cable box outputs an externally supplied cable broadcasting signal if its stored specific predetermined number is identical to cable box number supplied by the apparatus. The apparatus has a sync detector which receives an output of the cable box and generates a sync detection signal indicating whether a sync signal of a video signal is detected. A controller stores a plurality of predetermined cable box numbers, and outputs each of the predetermined cable box numbers sequentially to a cable box in response to the sync detection signal supplied from the sync detector. If the sync detector detects a sync signal, the controller sets a specific number of the installed cable box corresponding to the number which was output. Thus, the specific number of the cable box is automatically set in the video equipment.

Abstract: An infrared remote control unit including an integrated card reading device. The unit is used for purchasing products or services offered via a television monitor, such that the unit transfers data to a receiver connected to a television monitor connected via at least one modem to a control computer for processing and purchase authorization. The unit includes a card reader for reading data encoded on a magnetic stripe of a card. A microprocessor operatively connected to the card reader receives and reformats the encoded data. A transmitter connected to the microprocessor transmits the reformatted data to the receiver for the purchase.
