A cam program controlled system providing a continuous set point signal representing a time function relationship using an impulse or stepping drive motor. The drive motor impulses are electronically derived; and therefore, the system's time base or speed can be readily varied using switches and/or jumpers, instead of requiring gear train or motor changes. Also, the drive motor is coupled to the cam program through only a pinion and an anti-backlash drive gear. The cam follower arm is biased aga...

A key-operated digital program calculator is adapted to receive in succession a plurality of different kinds of input data items and perform a specified program calculation thereupon. The calculator is further provided with a display capable of visually displaying which kinds of input data items to be entered thereinto, whereby the operator is visually informed of the kinds of input data items to be next introduced into the calculator.

A program switching monitor is provided with means for preventing a central processing unit operating under control of a first program from switching to another program until certain conditions are met. Upon receipt of indications or data representative of the fact that all commands issued while the unit was operating under the control of the first program have been accounted for, program switching is permitted.

A programmer is disclosed for transmitting encoded signals to a pacing generator to effect the programming of a mode and/or parameter of the pacering generator's operation. The pacing generator applies stimulating pulses to the patient's heart in accordance with the programmed parameters and/or mode and includes a memory for storing the encoded signals and means therein for detecting the successful storage of the parameters in the memory to provide an indication thereof, whereby a generating cir...

In the disclosed camera with a program shutter, exposure control with a desired combination of shutter time and diaphragm value is made possible without variation of the gradient of the program curve, by shifting the program constant a specific amount.

A program control device is described having a rotatably driven program control body and a plurality of stationary actuatable programming members. These members are positioned adjacent a periphery of the body at different locations transverse to the direction of rotation of the body. One or more tabs each having a plurality of selectively removable contact segments are provided and demountable means support the tabs on the program control body adjacent its periphery for transport past and engage...

A micro program control system for use in a data processing system includes a subsidiary control memory for storing the first micro instructions of respective micro programs, and a control memory for storing the second and the remaining micro instructions of the respective micro programs. The subsidinary control memory is coupled to a main memory in which macro instructions of a program for the data processing system are stored. The operation code of the macro instruction includes a code to addr...

This invention relates to a program selection apparatus for program-controlled household appliances, such as washing machines in particular, which have a numeral keyboard for the input of program specifications and which have a display device coupled therewith via a control device for a continuous display of the program specifications inputted in sequence via the various keys of the numeral keyboard.

A device for use with a telephone transceiver to automatically generate any one of N stored dialing codes employs N digital phone number storage registers, and a set of N/2 pushbuttons. A display panel having N display areas on which the stored numbers may be written is supported in sliding relationship with the pushbuttons so that either of two display areas may be moved into operating relationship with each button. Switches controlled by the position of the panel and by the command buttons con...

In exposure means comprising, in combination, two shutter blades which also function as the aperture setting blades, a step-motor for displacing the shutter blades stepwise in response to the driving pulse or pulses, and a driving circuit for the step-motor. Slits are cut through the shutter blades so that the relative displacement between the shutter blades may be optically detected in order to control the stepwise rotation of the step-motor, thereby displacing the shutter blades to define the ...
