Patent number: 9496739Abstract: An apparatus balances a discharge in parallel battery configuration by having a battery pack (a) with a first battery system and a second battery system in parallel configuration, and a pulse width modulation device and (b) being interconnectable to a load. Each of the first and second battery systems has, in series and in order, a first voltage sensor, a resistor, a second voltage sensor, a string of battery cells, and a switching device. The first and second voltage sensor, in each battery system, measures an electrical current, used to calculate the voltage drop across each resistor. The voltage drop values for each battery system determine whether the pulse width modulation device alters or maintains the pulse width modulation applied to each battery system's switching device. By maintaining or altering the pulse width modulation applied to each switching device, the apparatus effectively balances the electrical current discharge from each battery system.Type: GrantFiled: December 6, 2012Date of Patent: November 15, 2016Assignee: Electrochem Solutions, Inc.Inventors: Brian Robert Peterson, Jon Carroll, Arden Phillip Johnson

Patent number: 8648636Abstract: In one embodiment, multiple (serializer-deserializer) SERDES channels are aligned by selectively slipping one or more of the incoming serial data streams one bit at a time prior to deserialization. Within each SERDES channel, a slip circuit slips the corresponding serial data stream by one bit (i.e., one unit interval (UI)) by extending the high portion of the duty cycle of a corresponding clock signal. The high portion of the clock signal is extended using a 3-to-1 mux that selects a fixed high signal, such as the high power supply rail, as an intermediate mux output signal whenever transitioning between two different applied clock signals that are offset from one another by one UI. In this way, the slip circuit avoids glitches that might otherwise result from switching directly between the two clock signals.Type: GrantFiled: May 13, 2013Date of Patent: February 11, 2014Assignee: Lattice Semiconductor CorporationInventors: Phillip Johnson, Richard Booth, Paulius Mosinkis

Patent number: 8164499Abstract: In an exemplary decision-feedback equalizer (DFE) of a serializer/deserializer (SerDes) receiver, a single current mirror array is shared by multiple current digital-to-analog converter (IDAC) functions. The DFE has an initial amplifier stage that applies an initial coefficient COEFF0 to an input data signal and a number of (e.g., five) additional amplifier stages that apply additional coefficients (e.g., COEFF1-COEFF5) to different delayed versions of the recovered output data stream. The outputs of the initial and multiple additional amplifier stages are summed to generate an equalized data signal that is applied to a clock-and-data recovery (CDR) circuit. Due to certain characteristics of the equalizer function, the multiple additional amplifier stages can be implemented using a single shared current mirror array, which save significant amounts of chip area compared to conventional implementations in which each additional amplifier stage has its own dedicated current mirror array.Type: GrantFiled: June 11, 2010Date of Patent: April 24, 2012Assignee: Lattice Semiconductor CorporationInventors: Richard Booth, Paulius Mosinskis, Phillip Johnson, David Onimus

Patent number: 7756982Abstract: Under the present invention, a request for a Uniform Resource Locator (URL) is received from a client on a server. Upon receipt, a corresponding session object is obtained, and a response identifier is generated. Based on the response identifier, it is determined whether the URL was previously requested by the client. If not, generation of a final response begins. As the response is being generated, a response refresh header is generated and returned to the client with a temporary response. The response refresh header contains a time value for causing the client to automatically send a subsequent request for the URL. After generation of the final response is complete, it is stored in a cache according to the response identifier. Then, when the subsequent request is received from the client, the final response is retrieved from the cache and served to the client.Type: GrantFiled: February 20, 2008Date of Patent: July 13, 2010Assignee: International Business Machines CorporationInventor: David Phillip Johnson

Patent number: 7616029Abstract: In one embodiment of the invention, a bias signal monitor has two signal comparators that compare two (power supply) voltages at two different bias points and a logic circuit that processes the outputs from the two signal monitors to generate a bias signal monitor output signal. The logic circuit implements hysteresis-based processing such that (1) if both signal comparators are active (indicating that a first voltage is greater than the second voltage relative to both bias points), then the monitor output is active, (2) if both signal comparators are inactive (indicating that the first voltage is not greater than the second voltage relative to either bias point), then the monitor output is inactive, and (3) if one signal comparator is active and the other is inactive, then the monitor output keeps its previous value. This hysteresis characteristic prevents relatively small oscillations between the voltages from changing the monitor output.Type: GrantFiled: October 9, 2007Date of Patent: November 10, 2009Assignee: Lattice Semiconductor CorporationInventors: William B. Andrews, Phillip Johnson, John Schadt, Harold Scholz

Clock-and-data-recovery system having a multi-phase clock generator for one or more channel circuits
Patent number: 7599457Abstract: In one embodiment of the invention, a clock-and-data-recovery (CDR) system has a multi-phase clock generator that generates a plurality of phase-offset clock signals and one or more channel circuits, each receiving a (different) input data signal and all of the phase-offset clock signals and generates an output data stream and a recovered clock signal. Each channel circuit has a plurality of data registers (e.g., flip-flops), each receiving the input data signal at its clock input port and a different one of the phase-offset clock signals at its data input port, such that the flip-flop is triggered at each (rising) edge in the input data signal. The channel circuit processes the outputs from the different flip-flops to select an appropriate phase-offset clock signal for use in sampling the input data signal to generate the output data stream, where the recovered clock signal is generated from the selected phase-offset clock signal.Type: GrantFiled: August 8, 2005Date of Patent: October 6, 2009Assignee: Lattice Semiconductor CorporationInventors: Phillip Johnson, Zheng Chen, Barry Britton -
Patent number: 7586344Abstract: In one embodiment, the invention can be a clock-generating circuit having one or more clock-processing circuits, each outputting a clock signal having an adjustable phase. Each clock-processing circuit comprises a divider and a divisor control circuit. Each divider divides an input clock signal by a respective divisor value and outputs a corresponding output clock signal whose period is determined by the divisor value and the period of the input clock signal. Each divider receives the respective divisor value from the corresponding divisor control circuit, wherein the divisor value is selected in order to achieve a desired frequency and phase for the corresponding output clock signal. Temporarily changing a divisor value can advance or delay the phase of the corresponding output clock signal without having to reset the divider.Type: GrantFiled: October 16, 2007Date of Patent: September 8, 2009Assignee: Lattice Semiconductor CorporationInventors: Richard Booth, Phillip Johnson, Zheng Chen
