摘要： The present invention recognizes that the limiting structures to size reduction for an optical encoder were the laser diode/photo diode package and the photodetector with amplifier package(s). The invention includes removing the discrete components from the laser diode cover package and mounting the much smaller discrete components on a base framework. The photodetector with amplifier package of the invention have an altered photodetector/amplifier geometry including shortening the leads between them. This resulted in significant size reduction of the encoder, a reduction in required gain and resulting increase in bandwidth. The entire base framework is temperature cooled by disposing two thermo-electric coolers between the base framework and an adjacent heat sink. Such positioning of the two coolers between the base framework and it's adjacent heat sink stabilizes both the laser diode's and the photo detector's outputs. In addition this novel design stabilizes the entire footprint/base of the encoder from thermal effects, whatever their origin.

摘要： Methods and apparatus for controlling a remote device using a command glove system are disclosed. An apparatus for controlling a device is arranged to be at least partially supported on and operated by a human appendage. The apparatus is further arranged to transmit signals to and receive signals from the device, and includes a positioning assembly mounted on the human appendage. The positioning assembly is arranged to respond to motions of the human appendage, and also transmits position signals that are used to control the device. The apparatus includes a braking assembly which is arranged to resist motion of the positioning assembly, and responds to resistance signals received from the device. The apparatus also includes a sense effecting assembly which transforms haptic signals received from the device into sensations felt by the human appendage.
