  • Patent number: 12016096
    Abstract: A load control device for controlling the amount of power delivered from an AC power source to an electrical load is operable to conduct enough current through a thyristor of a connected dimmer switch to exceed rated latching and holding currents of the thyristor. The load control device comprises a controllable-load circuit operable to conduct a controllable-load current through the thyristor of the dimmer switch. The load control device disables the controllable-load circuit when the phase-control voltage received from the dimmer switch is a reverse phase-control waveform. When the phase-control voltage received from the dimmer switch is a forward phase-control waveform, the load control device is operable to decrease the magnitude of the controllable-load current so as to conduct only enough current as is required in order to exceed rated latching and holding currents of the thyristor.

  • Patent number: 11961348
    Abstract: A maze-based switch generally having three functional blocks is disclosed. The first functional block handles communications by accepting an entered maze pattern from an external system controller and outputting the entered maze pattern (and optionally its directional complement) to the second functional block. The second functional block stores the maze pattern (and optionally its directional complement) to a permanent storage element and outputs the stored, entered maze pattern and its directional complement to a series of transistors in the third functional block. The third functional block is an electronic maze in which a correct maze pattern and its directional complement must be received by the transistors for the transistors to pass electrical power through the electronic maze to a connected element. The third functional block may alternatively be implemented with optical elements, optoelectronic elements, microelectromechanical elements, or elements formed by other microsystem technologies.

  • Patent number: 11927982
    Abstract: An integrated clock gate (ICG) includes an OR-AND-INVERT gate to receive a first enable and a second enable; a first inverter coupled to the output of the OR-AND-INVERT; a first NAND gate coupled to the output of the first inverter; a second NAND gate coupled to the output of the OR-AND-INVERT; and a second inverter to provide a clock which is gated based on logic values of the first enable and/or the second enable, wherein an output of the second inverter is received as input by the OR-AND-INVERT-gate. The ICG circuit reduces capacitance of input clk pin, which translates to lower switching power when clock is gated and reduction in dynamic power of clock network, since buffers in clock tree driving the ICG cells can be downsized. The ICG cell has the smallest transistor count (and area) when compared to existing ICG cell topologies.
