Patent number: 11313901Abstract: A system may include a trim circuit configured to provide a trim signal to a circuit under test. The trim circuit may be configured to adjust a trim value of the trim signal based on a selection signal and a value signal. The trim signal may cause a key characteristic of the circuit under test to change based on the adjusted trim value. The system may include a production tester configured to determine whether the key characteristic is within a threshold range. Responsive to the key characteristic being within the threshold range, the production tester may stop performing the trim procedure on the circuit under test. Responsive to the key characteristic not being within the threshold range, the production tester may adjust the value signal based on whether the key characteristic is greater than or less than the threshold range.Type: GrantFiled: December 9, 2019Date of Patent: April 26, 2022Assignee: SMART PRONG TECHNOLOGIES, INC.Inventor: Silvia Jaeckel

Patent number: 9780677Abstract: An electrical circuit for providing electrical power for use in powering electronic devices is described herein. The electrical circuit includes a primary power circuit and a secondary power circuit. The primary power circuit receives an alternating current (AC) input power signal from an electrical power source and generates an intermediate direct current (DC) power signal. The intermediate DC power signal is generated at a first voltage level that is less than a voltage level of the AC input power signal. The secondary power circuit receives the intermediate DC power signal from the primary power circuit and delivers an output DC power signal to an electronic device. The output DC power signal is delivered at an output voltage level that is less than the first voltage level of the intermediate DC power signal.Type: GrantFiled: February 25, 2016Date of Patent: October 3, 2017Assignee: Advanced Charging Technologies, LLCInventors: Michael H.

Patent number: 7334042Abstract: Methods and structures for managing connection requests within a SAS controller operating as an initiator device. A SAS initiator device maintains a table of information regarding known SAS devices in the SAS domain. An index value is used by each of a plurality of link layer processing elements in the SAS controller to access information in the table. The index value is fewer bits than the complete eight byte SAS address and the logic to manipulate and compare the index value is therefore simpler than that required to directly manipulate a full SAS address. Further, the information table is shared by each of the link layer processing elements to further reduce complexity from replication of circuits and logic in the SAS controller.Type: GrantFiled: August 18, 2004Date of Patent: February 19, 2008Assignee: LSI Logic CorporationInventors: Brian A.
