  • Patent number: 11022629
    Abstract: Techniques are provided for changing a range of an output circuit with little or no voltage or current glitch. In an example, a method of changing a range of an output signal can include providing a first level of the output signal at an output of a first amplifier based on a received setpoint signal and receiving a range change command. In response to the range change command an input of a second amplifier can be shorted to an output of the second amplifier for a first interval. At the end of the first interval and over a second interval, a first impedance between the input of the second amplifier and the output of the second amplifier can be increased, and a second impedance between the input of the second amplifier and the setpoint signal can be increased.

  • Patent number: 10815936
    Abstract: A flexible bearing assembly includes at least one metal end ring, a flexible bearing core having a plurality of layers of a resilient material between layers of a reinforcement material, and a phenolic composite material between and bonded to each of the at least one metal end ring and the flexible bearing core. A rocket motor assembly includes a chamber configured to contain a propellant and a movable thrust nozzle coupled to the chamber. The movable thrust nozzle includes a phenolic composite material between and bonded to each of a metal end ring and a flexible bearing core. Methods of forming a flexible bearing assembly include bonding a phenolic composite material to at least one metal end ring and bonding a flexible bearing core to the phenolic composite material. The flexible bearing core includes a plurality of layers of a resilient material between layers of a reinforcement material.

  • Patent number: 10778212
    Abstract: A system and method for controlling current-range switching to limit glitching includes a sense array connected between an input and a load. The sense array includes a parallel first and second branch circuits. The first branch circuit includes at least one first transistor, a first sense resistor, and a variable impedance control circuit. The variable impedance control circuit is configured to receive a control signal and generate a gate voltage of the at least one first transistor to establish an impedance of the sense array between the input and the load that is proportional to the control signal, including controlling the gate voltage of the at least one first transistor such that an impedance of the sense array transitions from a first value to a second value when connecting or disconnecting the first branch circuit between the input and the load while the input is connected to the load through the second branch circuit.
