  • Patent number: 12111084
    Abstract: The invention provides heat pump system a Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) or elastocaloric material core positioned in a housing and adapted to absorb thermal heat and store energy in response to a first fluid inputted at a first temperature. The housing is configured to receive the fluid at the first temperature via an inlet to cause the SMA or NTE or elastocaloric material core to change state. A device is configured to apply stress on the SMA or NTE or elastocaloric core in the housing to cause the SMA or NTE or elastocaloric core to change state. A support system is configured to engage with the material in the core to prevent the material buckling when the stress is applied wherein the support system comprises a series of buckling supports positioned along at least one length of the SMA or NTE or elastocaloric material core. The support system provides a mechanical buckling support and heat transfer optimisation for fluid flow in a SMA heat pump during compression.

  • Publication number: 20240305049
    Abstract: A cable connector for counting a number of plug-in events and preventing further plug in attempts after a threshold number of plug-in events have occurred. An inner sleeve is located inside an outer sleeve, and is designed to move relative to the outer sleeve. The inner sleeve further includes a tab on an outer surface of the inner sleeve. A gear wheel is located inside the outer sleeve and perpendicular to the inner sleeve and has a number of gear teeth. A toggle plug counter rotates the gear wheel one tooth in response to a plug-in action of the cable counter. When the gear wheel rotates to a point where the tab aligns with a notch in the gear wheel an inner spring at the opposite end of the inner sleeve causes the inner sleeve to move through the gear wheel such that further plugging action becomes difficult.

  • Publication number: 20240275337
    Abstract: Systems and methods for thermal droop compensation in power amplifiers are disclosed. In one aspect, a droop compensation circuit is added to a temperature-sensitive active bias circuit in a power amplifier chain. The droop compensation circuit relies on current mirroring to draw a trigger current that may be used by a correction circuit to create an additional bias signal that offsets temperature-induced droop in the power amplifier. Variations contemplate where the bias signal is injected within the power amplifier chain and what form the correction circuit may take (e.g., an attenuator, a variable gain amplifier (VGA), or the like). By compensating for temperature droop in this fashion, rapid pulsing signals that generate rapid pulses of heat may be transmitted across an effectively linear power amplifier chain without having to deal with droop effects.

  • Publication number: 20240275339
    Abstract: Systems and methods for thermal droop compensation in power amplifiers with field effect transistors (FETs) are disclosed. In one aspect, a droop compensation circuit having a heat-sensitive element is embedded in an amplifier in the amplifier chain. The heat-sensitive element tracks changes in temperature for the amplifier and generates a trigger signal for a correction circuit that modifies the amplifier chain to provide thermal droop compensation. Variations contemplate changes to the nature and location of the correction circuit. By compensating for temperature droop in this fashion, rapid pulsing signals that generate rapid pulses of heat may be transmitted across an effectively linear power amplifier chain without having to deal with droop effects. Particular aspects of a FET-based power amplifier may use diodes as a heat-sensitive element.
