  • Patent number: 11852186
    Abstract: An apparatus provides a latch with a rotary dial and a leaf spring with teeth that extend from a frame into an engaging position. Inward axial movement of the dial causes the dial to deform the leaf spring and the teeth to extend into the engaging position. In the engaging position, the dial supports the teeth and resists forces that might otherwise cause the teeth to unlatch. In the engaging position, a catch in a track on the dial engages a pin of the frame to maintain the engaging position. From the engaging position, a rotation of the dial unseats the catch and allows the dial to move axially outward and the teeth to recede into the frame.

  • Patent number: 11828780
    Abstract: Systems and methods are described for reporting capacitance of a capacitor of a power backup circuit comprising a plurality of metal-oxide-semiconductor field-effect transistors (MOSFETs). The system may also include a bleeder resistor and a voltage detection circuit. When capacitance monitoring is active, a first MOSFET may be turned off, causing the capacitor to be discharged via the bleeder resistor. After predetermined time intervals, a first drain voltage and a second drain voltage of the first MOSFET may be determined using the voltage detection circuit. The drain voltage readings at the different times may be used to determine the capacitance of the capacitor, which may be used to generate and transmit a report on capacitor performance and status.

  • Patent number: 11815428
    Abstract: An apparatus and system are provided for detecting leaks in cooling tubing using sensor cabling. In the leak detection system, a leak detection cable is routed along the full length of the cooling tube. The leak detection cable and the cooling tubing are encased within a shrunken tube, which leaves such a small gap between the cooling tubing and the heat-shrunk tube that leakage is distributed within the gap about the outside of the cooling tubing by capillary action. The relative position of the detection cable above or below the cooling tubing is then irrelevant, since the capillary action may overcome the effect of gravity and distribute leakage from the bottom of the tubing to a detection cable at the top of the tubing.

  • Patent number: 11812579
    Abstract: An apparatus is provided for locking rack-mounted electronic devices within a rack upon removal of one of the electronic devices from the rack. The apparatus includes a shaft rotatably connected to the rack and provided at each slot position with a set of paddles, including a locking paddle and a trigger paddle. With the rack populated with devices, the removal of one device from a slot causes a block attached to the device to urge against a trigger paddle, which rotates the shaft. As the shaft continues to rotate, with the motion of the block caused by the removal of the device, the locking paddle for each slot is rotated into a position such that an attempt to remove any of the other devices from the rack causes the associated block to abut the locking paddle, which does not yield.

    Abstract: A fan handle is operable to be coupled to a fan. The fan handle includes a first sheet and a second sheet. The first sheet has first apertures operable to receive fasteners to couple a fan guard with a first side of the fan. The first sheet forms a slot. The second sheet has second apertures operable to receive fasteners to couple a fan guard with a second side of the fan. The second sheet forms shoulders from which an extension portion extends. The extension portion is received in the slot of the first sheet. In a retracted configuration, the first sheet and the second sheet are substantially flush such that the shoulders abut against the first sheet. In an extended configuration, the extension portion is partially withdrawn from the slot such that the first sheet and the second sheet are curved and coupled with one another.

  • Patent number: 11783043
    Abstract: A method is provided for authenticating firmware images in an embedded system. The method may include loading and executing a trusted firmware using a pre-existing Secure Boot on a baseboard management controller (BMC). The BMC is configured as a master for an embedded system including System On Chips (SOCs) configured as slaves, out-of-band interfaces between the BMC and the SOCs, and flash storages in electrical communication with the SOCs. The method may also include pushing or uploading, by the BMC, a secure SOC firmware image to one of the SOCs using one of the out-of-band interfaces, verifying a digital signature extracted from the SOC firmware image by using a hash code calculated from the SOC firmware image and decrypted using a public key stored on the BMC and notifying a user about verification of the digital signature.

  • Patent number: 11758684
    Abstract: A method and system improve the cooling of computer power supply unit by eliminating a reverse flow of hot air caused by an imbalance in airflow between a power supply fan and a system fan. The method determines a correlation between a system fan speed and a heightened power supply fan speed that prevents the reverse flow of hot air into the power supply unit. During the operation of the power supply unit, the system fan speed is obtained and the heightened power supply fan speed is determined from the correlation. The power supply fan is then controlled using the heightened power supply fan speed setting.
