摘要： A method and apparatus for eliminating in at least one light emitter and light detector in a mouse design. This is done by using two conical shaped encoder wheels positioned so that they are almost touching each other. A single light emitter then is used to shine light at the junction, so that it passes through both cones. On the opposite side is a single chip, with two photodetectors integrated on each side. The chip is positioned so that light passing through the first conical encoder impinges on the first photodetector, while light passing through the second conical encoder impinges on the second photodetector. Thus, the two photodetectors can be integrated on a single chip, saving a separate photodetector chip. In addition, only a single LED is required.

This is done by using two conical shaped encoder wheels positioned so that they are almost touching each other. A single light emitter then is used to shine light at the junction, so that it strikes both cones. Adjacently located is a single chip, with two photodetectors integrated on each side. The chip is positioned so that light directed at the first conical encoder impinges on the first group of photodetectors, while light directed at second conical encoder impinges on the second group of photodetectors. Thus, the two photodetectors can be integrated on a single chip, saving a separate photodetector chip. In addition, only a single LED is required.

摘要： An electronic apparatus for storage and automatic dialing of telephone numbers comprises memory means including a plurality of tracks for storing a plurality of telephone numbers, these means being capable of storing data representing ten digits and a pause order, preparation and storage control means for monitoring and effecting the storage operations of these data, keyboard means for selecting one of the tracks, for ordering the storage of the data on the selected track, and for ordering automatic dialing of telephone numbers memorized in any selected track, and means for reading the data in the selected track and for dealing the corresponding telephone number by actuating a transmission device which sends pulses. The keyboard means, which comprises digits and pause-order entry keys, also comprises command keys, for ordering the call of a stored telephone number, involving first an operation of restoring and reclaiming the telephone line, and then dialing operations, and for ordering a continuation of dialing a number, without a line-restoring and-reclaiming operation, after a first part of this number has already been dialed, followed by a stopping of dialing responsive to a pause order.
