摘要： A position sensing apparatus and method includes a targeting device with a plurality of infrared transmitters or photodiode receivers attached to the targeting device and with corresponding receivers or transmitters mounted near a display monitor. The transmitters emit light signals that are received by the photodiode receivers. Receiver circuitry converts the light signals into signals representing the distance of the transmitters from the receivers. A processor then calculates the three-dimensional position and vector of the targeting device relative to the display monitor.

摘要： A microprocessor, having a memory element containing a plurality of multi-bit instruction words, an arithmetic logic (ALU) unit coupled to the memory element and responsive to at least a portion of each of the instruction words for performing data manipulations, and a controller for generating address signals that are communicated to the memory element to cause sequential access of the instruction words, includes a storage element that interconnects certain of the signal lines that communicate the instruction words to the ALU to the controller. In response to a first predetermined instruction word the storage element receives and stores the portion of the instruction word being conducted to the ALU. In response to a second predetermined instruction word, the content of the storage element is transferred to the controller to form an address signal.
