Patent number: 12743388Abstract: A system and method for managing a bus system when radio-frequency (RF) interference include a bus diagnostics engine determining when a bus system has been reset a predetermined number of times because RF interference has been detected within the bus system. A dynamic bus manager (DBM) is activated when the bus system has been reset a predetermined number of times because RF interference has been detected within the bus system. The DBM may decrease a speed of the bus system for a first instance once activated. After decreasing the speed of the bus system for the first instance, a bus diagnostics engine (BDE) may determine when the bus system has been reset because RF interference has been detected again. The DBM may decrease the speed of the bus system for a second instance in response to the BDE detecting RF interference after the first instance.Type: GrantFiled: February 11, 2025Date of Patent: September 22, 2026Assignee: Qualcomm IncorporatedInventors: Supreet Huilgol, Durga Khanal, Fujuan Guo Lee, Robert Shen, Malcolm Wells, Narmathapriya Subramanian

Patent number: 5841724Abstract: A circuit for connecting a memory cell matrix to voltage sources includes a voltage sensor responsive to the voltage levels of a first voltage source and of a second voltage source by producing a sense signal, and a voltage source coupler connected between the memory cell matrix and the voltage sensor. When the first voltage source voltage level is greater than a predetermined threshold voltage level, the sense signal causes the voltage source coupler to drive the first voltage source voltage level into the memory cell matrix. When the first voltage source voltage level falls to the threshold voltage level, the sense signal also causes the voltage source coupler to drive the second voltage source voltage level into the memory cell matrix to sustain memory cell data.Type: GrantFiled: June 12, 1997Date of Patent: November 24, 1998Assignee: Enable Semiconductor, Inc.Inventors: Mark S.
