Abstract: An electronic digital programmable wall thermostat system for controlling heating and cooling systems supplying an indoor area or space. The thermostat includes a digital clock, a display for displaying desired parameters of time and temperature and a data entry keyboard for programming the thermostat to maintain desired temperatures during selected time intervals. The heart of the system is a digital processor with memory, which responds to signals from a temperature sensing means which includes an analog to digital converter for controlling the heating and cooling systems in accordance with the sequence programmed therein. The system provides for conservation of energy by automatic system shutdown or setback when the heated or cooled space is unoccupied or during periods when activity in the space is minimal such as during sleeping hours.

Abstract: An electronic calculator system of the type having a keyboard input and a visual display readout is implemented in MOS/LSI semiconductor chips having a data memory, an arithmetic unit, a read-only-memory for storing instruction words, and control circuitry for operating the system in response to keyboard inputs, all in monolithic semiconductor units. The keyboard and display are scanned by timing signals generated in the semiconductor unit by a register associated with the data memory.

Abstract: The specification discloses an electrode configuration for a three phase charge coupled device having a channel for accommodating movement of charge packets. A first phase bus is formed on two levels and is disposed along one side of the channel and includes an array of first phase electrodes which span the channel on two levels. Second and third phase busses are disposed along the other side of the channel and include arrays of second and third phase electrodes formed on two levels which span the channel and which extend between adjacent ones of the first phase electrodes.

Abstract: Adjacent CCD phase electrodes in different levels separated by an insulating layer are connected to multi level phase buses on one side of the phase electrode by secondary bus means extending from one electrode in one level to an electrode of the same phase spaced therefrom in a different level by way of a vias through the insulation layer at a location intermediate the buses and the phase electrodes.

Abstract: An electronic calculator system of the type having a keyboard input and a visual display is implemented in MOS/LSI semiconductor chips having a data memory, an arithmetic unit, a read-only-memory for storing instruction words, and control circuitry for operating the system in response to keyboard inputs by selecting addresses for instructions from the read-only-memory, all of which is located in monolithic semiconductor units. A technique is provided for turning off the display after a selected time period by holding an instruction word in an instruction register while repeatedly incrementing an address register for the ROM until it overflows, then branching to an address defined in such instruction word. This is repeated until the selected time period is reached.
