Publication number: 20240125148Abstract: A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventors: Jeffrey A. Grant, David N. Berglund, Hrishikesh P. Gogate, Justin A. Richardson, Wiliam W. Warren, Andrew W. Moock

Patent number: 11942468Abstract: A packaged semiconductor die may include a package terminal array comprising a plurality of terminals, wherein a spacing between the plurality of terminals of the ball grid array is less than 0.5 mm. First and second high-voltage circuits of the die may output a differential signal to a first and second terminal that may exceed 15 volts, in which the first high-voltage circuit and the second high-voltage circuit are positioned symmetrically around an axis and in which the first terminal and the second terminal are located at an edge of the package terminal array. A low-voltage circuit may be coupled to a third terminal and positioned between the first high-voltage circuit and the second high-voltage circuit, wherein the low-voltage circuit comprises circuitry organized in columns aligned along an axis and having a width defined by a fraction of the terminal spacing pitch.Type: GrantFiled: May 25, 2021Date of Patent: March 26, 2024Assignee: Cirrus Logic, Inc.Inventors: Aleksey Khenkin, Justin Richardson, Michael Robinson, David Patten
