Patent number: 11815428Abstract: 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.Type: GrantFiled: July 29, 2021Date of Patent: November 14, 2023Assignee: ZT Group Int'l, Inc.Inventors: Mahesh Kumar Varrey, Chen An

Patent number: 11812579Abstract: 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.Type: GrantFiled: April 28, 2021Date of Patent: November 7, 2023Assignee: ZT Group Int'l, Inc.Inventors: Mark Alan Hammond, Jared Scott Harlan, Ryan Signer
