Patent number: 10574127Abstract: In an actuator (camera driver) according to the present invention, when a movable unit is in a neutral position in which the movable unit has rotated around neither an axis nor an axis, a first synthetic vector and a second synthetic vector are directed toward an object to be driven with respect to a plane including the both axes. The first synthetic vector is defined by synthesizing together two first vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of first driving magnets and the pair of magnetic yokes. The second synthetic vector is defined by synthesizing together two second vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of second driving magnets and the pair of magnetic yokes.Type: GrantFiled: March 21, 2017Date of Patent: February 25, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Teruyuki Takizawa, Hironori Tomita, Tsutomu Shimomura, Masakazu Kobayashi, Yasuaki Kameyama, Hirohide Ichihashi

Patent number: 9934191Abstract: In order to control individual circuit nodes coupled to a common serial line, each of the different circuit nodes must be assigned a locally unique address. However, mass manufactured electronics are manufactured as identical electronic devices. Thus, several techniques are presented for assigning unique addresses to identical electronic devices coupled to a common serial line. One set of techniques uses a local sensor that is stimulated in order to specify a single device on the serial line. Another set of techniques measures a pulse presented onto the common serial by a circuit node to determine its relative position on the serial line.Type: GrantFiled: July 31, 2014Date of Patent: April 3, 2018Assignee: NEOFOCAL SYSTEMS, INC.Inventors: Mark Peting, Dale Beyer, Tsutomu Shimomura

Patent number: 8890434Abstract: To control multiple electronic circuits organized in a series configuration, this document introduces a single-wire power, control, and feedback system. Specifically, individually controlled electronic circuits are arranged in a series configuration that is driven by a control unit located at the head of the series. The head-end control unit provides both electrical power and control signals down a single wire to drive all of the electronic circuits in the series in a manner that allows each electronic circuit to periodically draw power from the single wire and receive control information. Each electronic circuit in the series may communicate back to the head-end control unit by drawing power or not during a specified time slot.Type: GrantFiled: February 14, 2013Date of Patent: November 18, 2014Assignee: Neofocal Systems, Inc.Inventors: Tsutomu Shimomura, Mark Peting, Dale Beyer

Publication number: 20140333269Abstract: Data may be encoded onto a direct current power line by modulating the current on that direct current power line. One method of modulating the current is by placing an inductor on the power line and then using a controlled transistor that turns on and turns off. The inductor will ensure that current keeps flowing but the transistor will induce changes in the current pattern. The excess current from when transistor is turned off must be diverted. Furthermore, to create symmetrical current changes, the inductor should be reverse biased. Thus, a circuit is created that sinks the excess current from when the transistor is turned off and used to reverse bias the inductor.Type: ApplicationFiled: May 6, 2014Publication date: November 13, 2014Applicant: NEOFOCAL SYSTEMS, INC.Inventors: Mark Peting, Dale Beyer, Tsutomu Shimomura

Patent number: 8701140Abstract: A broadband data broadcast system that allows rich multimedia content to be delivered to a plurality of subscribers is disclosed. The broadband data broadcast system operates by multiplexing a plurality of rich multimedia digital information streams together at a centralized data broadcast center. The data broadcast center then broadcasts the multiplexed digital information stream on a broadcast medium such as satellite broadcasts, radio frequency broadcasts, or digital television broadcasts. A large number of receiver systems receive the broadcast signal and demodulate the broadcast signal to retrieve the multiplexed digital stream. The receiver system extracts a subset of digital information streams that the particular receiver system's owner has designated are of interest. The receiver system caches the interesting digital information stream for later access. The receiver system outputs the interesting digital information streams to a client system upon demand.Type: GrantFiled: April 1, 2005Date of Patent: April 15, 2014Assignee: ARRIS Enterprises, Inc.Inventors: Tsutomu Shimomura, Steve Waltman, Mark Peting, Castor Fu, Dag H.

Patent number: 8456098Abstract: Direct current circuits always require a voltage source consisting of a positive voltage and a ground. To power a plurality of a direct current circuit nodes one must traditionally supply a power supply line and a ground line to each circuit node. To simplify wiring, a single conductor system of powering a plurality of circuit nodes is disclosed wherein each circuit node has only two external connections and the circuit nodes are coupled in series. Specifically, each individual circuit node has an integrated circuit and a capacitor. A power circuit within the integrated circuit then directs current from an input into the capacitor to create a local power supply and shunts current from the input to an output when not directing current into the capacitor.Type: GrantFiled: December 7, 2011Date of Patent: June 4, 2013Assignee: Memoir Systems, Inc.Inventors: Mark Peting, Dale Beyer, Tsutomu Shimomura

Publication number: 20130095650Abstract: Waffle transistors are used within an integrated circuit when a transistor must carry an amount of current greater than the amount of current carried by a typical transistor in the integrated circuit. In a waffle transistor a set of source areas and drain areas are arranged in a checkerboard pattern. The source areas must all be connected together and the drain areas must all be connected together. To efficiently connect the source (or drain) areas together, a serpentine metal interconnect pattern is used. The serpentine pattern reduces the amount of metal required outside of the array. The serpentine pattern may be improved with offset contacts in the source and drain areas that cause the serpentine metal interconnects to be straighter.Type: ApplicationFiled: October 14, 2011Publication date: April 18, 2013Applicant: NEOFOCAL SYSTEMS, INC.Inventor: Tsutomu Shimomura
