Publication number: 20160004610Abstract: Apparatuses, systems and methods are disclosed for tolerating fault in a communications grid. Specifically, various techniques and systems are provided for detecting a fault or failure by a node in a network of computer nodes in a communications grid, adjusting the grid to avoid grid failure, and taking action based on the failure. In an example, a system may include receiving grid status information at a backup control node, the grid status information including a project status, storing the grid status information within the backup control node, receiving a failure communication including an indication that a primary control node has failed, designating the backup control node as a new primary control node, receiving updated grid status information based on the indication that the primary control node has failed, and transmitting a set of instructions based on the updated grid status information.Type: ApplicationFiled: June 23, 2015Publication date: January 7, 2016Inventor: Richard Knight

Publication number: 20150242233Abstract: The disclosure relates to systems and methods for defining a processor safety privilege level for controlling a distributed memory access protection system. More specifically, a safety hypervisor function for accessing a bus in a computer processing system includes a module, such as a Computer Processing Unit (CPU) or a Direct Memory Access (DMY) for accessing a system memory and a memory unit for storing a safety code, such as a Processor Status Word (PSW) or a configuration register (DMA (REG)). The module allocates the safety code to a processing transaction and the safety code is visible upon access of the bus by the module.Type: ApplicationFiled: March 12, 2014Publication date: August 27, 2015Inventors: Simon Brewerton, Glenn Farrall, Neil Hastie, Frank Hellwig, Richard Knight, Antonio Vilela

Patent number: 9032258Abstract: Some embodiments of the present disclosure relate to a watchdog timer having an enhanced functionality that enables the watchdog timer to monitor a process flow of the microprocessor on a task-by-task basis that enables a simple output signal to be used to determine if the watchdog timer is malfunctioning. The watchdog timer has a state machine that increments a state variable from an initial value over a watchdog period. A deterministic service request, received from a microprocessor, controls operation of the watchdog timer. The deterministic service request has an indicator of a monitoring operation to be performed, a password, and an estimated state variable. A comparison element determines if the microprocessor is operating properly based upon a comparison of the received password to an expected password and the received estimated state variable to an actual state variable.Type: GrantFiled: September 14, 2012Date of Patent: May 12, 2015Assignee: Infineon Technologies AGInventors: Richard Knight, Simon Brewerton

Patent number: 9018800Abstract: Series strings of photovoltaic (PV) modules with integrated dc-dc microconverters that can function in buck, boost, or an intermediate bridge mode based on the load can harvest more energy than conventional central-inverter architectures, especially when the arrays are partially shaded or when the modules are mismatched. The integrated multi-mode dc-dc converter includes a maximum power point tracking (MPPT) algorithm that can track the true MPP, even when a PV module becomes partially-shaded, without scanning the entire output voltage range. The algorithm compares power levels only at a voltage that occurs when a bypass diode bypasses a portion of an associated PV module, and multiples thereof.Type: GrantFiled: July 29, 2011Date of Patent: April 28, 2015Assignee: Texas Instruments IncorporatedInventors: Richard Knight Hester, Sairaj Vijaykumar Dhople, Nagarajan Sridhar

Patent number: 8115345Abstract: A low-EMI switched circuit comprises two or more switches, wherein impedance transitions of the switches are overlapped and the overlap is varied using variable switch timing based on an output power level of the switched circuit. The variable timing results in a variable impedance overlap between the switches. In one example, when one switch turns off (begins a low to high impedance transition) and a second switch turns on (begins a high to low impedance transition), a greater timing delay in beginning the second switch's transition results in a higher switch impedance overlap than a shorter delay does. If the variable timing is based on output power of the switched circuit, the variable delay can operate to reduce fly-back voltages at high power output levels and reduce shoot-through current at lower power levels, reducing EMI and quiescent current of the switched circuit.Type: GrantFiled: September 28, 2009Date of Patent: February 14, 2012Assignee: Texas Instruments IncorporatedInventors: Patrick Peter Siniscalchi, Richard Knight Hester
