  • Patent number: 11920517
    Abstract: A turbine engine heat exchanger has an array of heat exchanger plates mounted to an inner case wall for providing heat transfer from a bleed flowpath to a bypass flowpath. Each plate has: first and second faces along the bypass flowpath; a proximal edge mounted to the inner case wall; an inlet along the proximal edge; an outlet along the proximal edge; and a branch segment of the bleed flowpath passing from the inlet to the outlet.

  • Publication number: 20220263770
    Abstract: Methods and apparatus for application-to-application resource reservation schemes for precision networking. Hardware resources, such as interconnects and processing resources, are reserved for forwarding and processing data along flow paths for end-to-end delivery of data between applications running on respective platforms communicating over a network. Operating system and/or hypervisor resources are also reserved. The reservations may be based per application, per virtual machine (VM), or per container, and reservations for multiple applications/VMs/containers are supported. The interconnects include chip-to-chip, socket-to-socket (for multi-socket platforms), and die-to-die interconnects. Reservations for on-chip fabrics are also supported.

  • Patent number: 4380742
    Abstract: A circuit for synchronizing the frequency and/or phase of an output frequency signal (f.sub.0) to a reference frequency signal (f.sub.ref) is disclosed. A digitally controlled oscillator produces an output frequency signal which varies dependent upon an input digital signal which also is varied. A comparator means is coupled to the oscillator and the reference signal for determining the presence or absence of a frequency or phase difference between the output frequency signal and the reference frequency signal and generates a digital signal to the oscillator indicating whether the output frequency signal should be increased or decreased. In one embodiment, the comparator means comprises an up/down counter and the digitally controlled oscillator comprises a digital-to-analog converter (DAC) coupled to an oscillator circuit. The output of the oscillator circuit (f.sub.0) is fed back through a divide by N counter circuit.

  • Patent number: 4358729
    Abstract: Disclosed is a method and circuit for automatically adjusting the firing angle of a switching element, such as a thyristor or triac, to minimize surge currents produced in reactive loads in AC power applications. A typical application would be in a microwave oven controller when the circuit would be used as an interface between the microwave oven control circuitry and the thyristor driving a magnetron. The circuit is comprised of a digital-control, phase-locked loop oscillator which produces a series of triggering pulses which are synchronized with the AC line voltage; the oscillator oscillates at a known frequency and clocks a counter during one half-cycle of the line voltage, resetting the counter during the opposite half-cycle. A peak fire detection circuit is coupled to the oscillator. An enable signal is generated by the microwave oven control circuitry. Since the oscillator frequency is known, the AC line voltage peak occurs at a known state of the counter.
