Publication number: 20240077925Abstract: Circuits, systems and methods are provided. A circuit includes a subsystem, an interface, and a debugger. The interface includes power processing and management (PPM) circuitry coupled to the subsystem, and arbitration logic coupled to the PPM circuitry. In operation, the debugger issues a debug request to the arbitration logic to perform a debug operation on the subsystem, and, in response to the debug request, the arbitration logic provides an interrupt associated with the subsystem to the PPM circuitry. The PPM circuitry, in response to the interrupt and a determination that the subsystem is OFF, powers on the subsystem and provides a notification to the arbitration logic indicating that the subsystem is ON. The PPM circuitry also receives a notification from the arbitration logic that the debug operation related to the debug request is complete, and powers off the subsystem in response to that notification.Type: ApplicationFiled: November 8, 2023Publication date: March 7, 2024Inventors: Jose Luis FLORES, Gary Augustine COOPER, Amritpal Singh MUNDRA, Anthony LELL, Jason Lynn PECK

Patent number: 11333463Abstract: A modular firearm holster safety retention assembly is operable with a holster to prevent unauthorized extraction or accidental drop of a firearm from holster. The assembly comprises a saddle that receives the barrel of a firearm, and a pivot release arm that couples to the saddle to selectively restrict movement or release the firearm in the holster. The pivot release arm detachably couples to the saddle. The pivot release arm has a first end with a protruding locking nub that engages the ejection port of firearm to restrict movement thereof; and a second end that is urged away from the saddle to disengage the locking nub from the firearm ejection port to disengage firearm from saddle. The saddle and the pivot release arm have interlocking wedges that restrict forceful removal of the firearm from holster. The saddle has a pivot stop to prevent overleveraging of pivot release arm.Type: GrantFiled: May 26, 2021Date of Patent: May 17, 2022Assignee: U.S. DUTY GEAR, INC.Inventor: Jose Luis Flores

Publication number: 20210372735Abstract: A modular firearm protection and alignment assembly and method of operation integrates with a firearm holster to align and protect the firearm. The assembly is arranged, such that a firearm is centrally aligned, and provided with a fixed stopping point in the holster. An upper base includes a platform defined by a protruding alignment member that projects upwardly from the platform. The platform serves as a barrier to prevent the firearm from sliding beyond a predetermined point into the holster. The protruding alignment member projects from the bottom of the holster to receive, and concentrically align, the barrel of the firearm with the holster. A lower base joins with the upper base through use of a fastening mechanism. The lower base has an elongated panel that couples to the upper base, and a circular panel that protects light accessories mounted on the firearm, and drains fluids from the holster.Type: ApplicationFiled: May 26, 2021Publication date: December 2, 2021Inventor: Jose Luis Flores

Patent number: 9798344Abstract: This invention is an electronic circuit with a low power retention mode. A single integrated circuit includes a circuit module and a droop switch circuit supplied by a voltage regulator. In a normal mode a PMOS source-drain channel connects the voltage regulator power to the circuit module power input or isolates them dependent upon a power switch input. In a low power mode a second PMOS connected between the first PMOS gate and output diode connects the first PMOS. This supplied the circuit module from the voltage regulator power as reduced in voltage by a diode forward bias drop. This lower voltage should be sufficient for flip-flops in the circuit module to retain their state while not guaranteeing logic operation. There may be a plurality of chain connected droop switch each powering a corresponding circuit module.Type: GrantFiled: August 15, 2016Date of Patent: October 24, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ramakrishnan Venkatasubramanian, Shane Stelmach, Soman Purushotaman, Michael Gill, Jose Luis Flores

Patent number: 9618956Abstract: A power supply for an electronic circuit enables a low effort retention mode. During a normal mode a circuit module is supplied a first voltage sufficient for a controlled circuit to operate. During the low effort retention mode the circuit module is supplied with a second voltage lower than the first voltage. The second voltage is sufficient for flop-flops to retain their state but not sufficient to guarantee proper circuit operation. The second voltage is produced by a voltage drop (droop) from the first voltage. The preferred embodiment includes a System On Chip and one external voltage regulator and an on-chip droop circuit for each circuit module.Type: GrantFiled: June 8, 2015Date of Patent: April 11, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Michael Gill, Ramakrishnan Venkatasubramanian, Shane Stelmach, Jose Luis Flores

Patent number: RE46193Abstract: An embedded megamodule and an embedded CPU enable power-saving through a combination of hardware and software. The CPU configures the power-down controller (PDC) logic within megamodule and can software trigger a low-power state of logic modules during processor IDLE periods. To wake from this power-down state, a system event is asserted to the CPU through the module interrupt controller. Thus the entry into a low-power state is software-driven during periods of inactivity and power restoration is on system activity that demands the attention of the CPU.Type: GrantFiled: June 12, 2014Date of Patent: November 1, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Timothy David Anderson, Lewis Nardini, Jose Luis Flores, Abhijeet Chachad, Raguram Damodaran, Joseph R.
