Eight Applications Specific Integrated Circuits (ASICs) for use in stand-alone end products and other devices requiring a 24 hour memory. They have a real-time clock as well as memory that stores On and Off Switch closures with the ability to repeat them. They also have power management to allow them to operate by receiving their power through the load they are switching. They also have LED drivers to indicate the function being performed. They can store a resolution of two minute or one minute intervals of On and Off Switch closures per 24 hour period depending upon the amount memory integrated into the ASIC. Only a few external components are required to create end products and/or utilize these ASICs in another product.

A non-contact switch control system includes: a switch set, configured to receive a sensing signal from a sensed target, the switch set including a first non-contact switch and a second non-contact switch, the sensing signal including a first sensing signal and a second sensing signal; a storage unit, configured to store a control program; and a processing unit, connected to the switch set and the storage unit and configured to execute the control program and control the switch set based on the sensing signal.

Method and device for safe switching of a signal between a first and second point. Device includes a first branch having a first switch and second switch arranged between the first and second point, and a parallel second branch having a third switch and fourth switch. A testing device instructs a control unit, in a test sequence, to open the first switch for a first period of time, open the second switch for a second period of time, open the third switch for a third period of time, and open the fourth switch for a fourth period of time. Neither the first nor second periods of time overlap with the third or fourth period of time. A testing unit tests functioning of the switches during respective period of time, and generates an error signal in the event of a malfunction of at least one switch.

An automatic power off circuit of a non-rebound switch includes: a power switch circuit, the non-rebound switch, a trigger circuit, a controller, and a power on-off control circuit; the trigger circuit is connected with the power switch circuit and the non-rebound switch, and configured to send a turn-on signal to the power switch circuit to turn on the power switch circuit when the non-rebound switch is turned on; the controller is connected with the power switch circuit and configured to detect continuous turn-on time of the non-rebound switch and output a turn-off signal in response to the continuous turn-on time exceeding a preset timing time; the power on-off control circuit is connected with the controller, the power switch circuit and the non-rebound switch, and configured to turn off the power switch circuit by using the turn-off signal. A problem that non-rebound switches cannot be automatically powered off can be solved.

This patent outlines the design of a family of Applications Specific Integrated Circuits (ASICs) for specific use in stand-alone end products and other devices needing 24 hour timer functions. These ASICs have a built-in real-time clock as well as a memory storage function remembering On and Off switch activity with the ability to repeat it. The ASICs have LED drivers indicating the function being performed. The power-on indicator also doubles as night light feature.

These ASICs can store two minute or one minute intervals of power switch changes per day depending upon the amount of shift register memory placed in the ASICs. The memory function doubles as a static shift register for storage as well as providing a large portion of the real time 24 hour clock. These ASICs fully integrate most of the electronics required for stand-alone memory timers. Only a few additional components are required to fully create products using these ASICs.
