  • Publication number: 20240107710
    Abstract: Systems and methods for providing an electronic cooling apparatus comprising a chassis having an internal space that is sized/shaped to receive/structurally support circuit card(s). The internal space defined by sidewalls with a channel formed therein in which a coolant is disposed. The coolant is in thermal communication with the circuit card(s) via the sidewall(s) when the circuit card(s) is(are) disposed in the chassis. A refrigerant-based cooling system is disposed in the chassis and comprises an evaporator having inlet/outlet ports coupled to the channel of the chassis to define a first closed-loop channel for the coolant within the chassis. The evaporator facilitates heat transfer from the coolant to a refrigerant flowing through a second closed-loop channel of the chassis at least partially defined by the evaporator. A pump is disposed in the chassis and configured to cause the coolant to flow through the first closed-loop channel.

  • Publication number: 20240075304
    Abstract: A medical device includes wake circuitry and telemetry circuitry. The wake circuitry is configured to receive a first set of data from a device associated with the medical device, where the first set of data is received at a frequency band. The wake circuitry is configured to output a set of pulses based on the first set of data. The wake circuitry is configured to detect a data pattern using the set of pulses. The wake circuitry is configured to output an activation signal in response to a determination that the data pattern satisfies a data pattern requirement. The telemetry circuitry is configured to output a second set of data in response to receiving the activation signal. The second set of data is transmitted at the frequency band. The telemetry circuitry is configured to establish a communication session with the device using the second set of data.

  • Patent number: 10767660
    Abstract: A support assembly and method for supporting an internal assembly in a casing of a turbomachine are provided. The support assembly may include a support member that may be slidably disposed in a recess formed in the internal assembly and configured to engage an inner surface of the casing. A biasing member may be disposed in a pocket extending radially inward from the recess. The biasing member may at least partially extend into the recess and may be configured to apply a biasing force to the support member disposed therein.
