Patents by Inventor Seth N. Kazarians

Seth N. Kazarians has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11960311
    Abstract: A linear voltage regulator with isolated supply current is disclosed. The voltage regulator is configured and controlled such that its output current closely matches its input current (any quiescent current consumed by the regulator is negligible relative to the amount of current passed by the regulator). In certain implementations, the voltage regulator is implemented as an analog component. In other implementations, the voltage regulator includes or cooperates with digital elements, such as an analog-to-digital converter, a digital processing core, or a digital-to-analog converter.

  • Publication number: 20230344255
    Abstract: Embodiments are provided for dynamic management of charge. The techniques may involve obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge, and responsive to determining the amount of time remaining before reaching a second estimated readiness time is less than an updated estimated charging time to charge the energy storage element at the intermediate state of charge to the target state of charge, using a second charging rate to charge the energy storage element to the target state of charge, wherein the second charging rate is greater than the first charging rate.

  • Patent number: 11650248
    Abstract: A test system for measuring electrical current consumption of a device under test (DUT) includes a capacitor with power and ground terminals; a voltage regulator with input and output terminals; first and second switching elements; and a controller. The voltage regulator generates a DUT operating voltage based on its input voltage. The first switching element is arranged between a direct current (DC) voltage source and the regulator input, and the second switching element is arranged between the DC voltage source and the capacitor. The controller operates the switching elements to charge the capacitor, and to configure the test system for measuring operating current of the DUT using the capacitor as the power source.

  • Publication number: 20230098831
    Abstract: Electromechanical actuation systems and related operating methods are provided. A method of controlling an electromechanical actuator in response to an input command signal at an input terminal involves determining a commanded actuation state value based on a characteristic of the input command signal, generating driver command signals based on the commanded actuation state value and an actuator type associated with the electromechanical actuator, and operating driver circuitry in accordance with the driver command signals to provide output signals at output terminals coupled to the electromechanical actuator.

  • Publication number: 20210281092
    Abstract: Devices, systems and methods are provided for networked dynamic management of charge. A processor-implemented method involves charging an energy storage element from an initial state of charge to a holding state of charge, maintaining the energy storage element at the holding state of charge, receiving, via a network, an indication to complete charging the energy storage element, and in response to receiving the indication, charging the energy storage element from the holding state of charge to a target state of charge.
