Patent number: 11099222Abstract: A near-field capacitive data communication system that uses a variable capacitive device such as a PIN diode to change the capacitance of a conductive plate in response to either a high or low data signal. A detector attached to a second conductive plate that is in proximity to the first conductive plate measures the capacitance of the first conductive plate and outputs a corresponding data signal. The technique is wireless, since the two conductive plates are not in electrical contact with one-another, but rather share their static electric fields. A microcontroller can act as a detector by baselining the capacitance of the first conductive plate when its capacitance is in the low capacitance state. The technique is ideal for communication between a pair of toys that can be brought in close proximity to one-another. Since no radio frequencies are used, no special testing or governmental electromagnetic compatibility rules apply.Type: GrantFiled: January 20, 2019Date of Patent: August 24, 2021Inventors: Christopher T.

Patent number: 8891663Abstract: A method and apparatus for transmitting digital data in a cellular environment. Adjacent cells of the cellular system are prevented from simultaneously transmitting data. Because the noise from transmissions of adjacent cells is a primary source of interference, the transmission rate of power limited base stations can be dramatically increased when the noise from adjacent cells is eliminated. The transmissions to each subscriber station are made at a fixed transmission power level. However, the data rate of transmitted signals differs from one subscriber station to another depending the path loss differences. In a first exemplary embodiment, the data rate of transmissions to a subscriber station is determined by selecting an encoding rate for the transmitted signal while holding the symbol rate constant.Type: GrantFiled: September 14, 2004Date of Patent: November 18, 2014Assignee: QUALCOMM IncorporatedInventor: Ephraim Zehavi

Patent number: 8842779Abstract: Embodiments of user equipment and methods for determining IQ imbalance parameters are described. In some embodiments, a method for determining in-phase (I) and Quadrature (Q) imbalance (IQ imbalance) parameters based on a known signal in a dual-carrier receiver using at least one controllable frequency offset includes receiving a known signal modulated onto a first radio frequency (RF) carrier frequency and a second RF carrier frequency different than the first RF carrier frequency. The known signal is downconverted to a baseband signal for the carriers by conversion from the respective RF carrier frequencies to an intermediate frequency (IF) using a common RF local oscillator (LO) and by further conversion from IF to baseband using carrier specific IF LOs, where a controllable frequency offset is used. Any controllable frequency offset is removed from the baseband signal for the first and second carriers to produce representations of the received signals.Type: GrantFiled: August 23, 2013Date of Patent: September 23, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Chester Park, Jim Svensson

Patent number: 8831160Abstract: An apparatus includes a first clock source, a second clock source and circuitry configured to supply a clock signal to a circuit. The circuitry operates to change the clock signal from one frequency to another different frequency. This change is made in a manner whereby no clock signal is supplied during a period of time when the change from the one frequency to the another different clock frequency is being made.Type: GrantFiled: January 17, 2013Date of Patent: September 9, 2014Assignees: STMicroelectronics (Research & Development) Limited, STMicroelectronics (Grenoble 2) SASInventors: Andrew Ferris, Ignazio Antonino Urzi

Patent number: 8831077Abstract: Systems and methods are disclosed for communicating on a pilot wire between Electric Vehicle Service Equipment (EVSE) and an Electric Vehicle (EV). The EVSE and EV exchange a Pulse Width Modulation (PWM) signal on the pilot wire to control charging operations of the EV. Data communications may also be transmitted on the pilot wire, such as between transmit and receive modems. The modems transmit communication signals either continuously, without regard to the state of the PWM signal, or only when the PWM is in an off-state. If transmitting while PWM is on, the modem needs a large coupling impedance and/or a large signal injection. To transmit only when the PWM is off, the modem may use a blocking diode in the coupling circuit or may synchronize to the pulses in the PWM signal.Type: GrantFiled: June 17, 2011Date of Patent: September 9, 2014Assignee: Texas Instruments IncorporatedInventors: Badri Varadarajan, Il Han Kim, Anand Dabak, Edward Mullins

Patent number: 8824564Abstract: Aspects of a method and system for redundancy-based decoding of video content are provided. A bit sequence comprising video content may be decoded in a multilayer process based on a decoding algorithm and at least one physical constraint. The decoding algorithm may be based on the Viterbi algorithm. Whether the bit sequence comprises video content may be determined based on information provided by a portion of a packet header or by packet priority information necessary for enabling quality of service applications. The physical constraint may be based on border, DC component, and/or low frequency continuity between neighboring discrete cosine transform (DCT) blocks. The physical constraint may also be based on the consistency of video data coded by a variable length coding (VLC) operation. At least one physical constraint test may be performed on selected estimated video bit sequences to select a decoded output video bit sequence.Type: GrantFiled: September 14, 2012Date of Patent: September 2, 2014Assignee: Broadcom CorporationInventors: Arie Heiman, Jeyhan Karaoguz

Patent number: 8804891Abstract: A frequency detector includes a multi-phase clock generation unit, a sampling unit connected to the multi-phase clock generation unit and a digital logic unit connected to the sampling unit. An inputted single-phase clock is received by the multi-phase clock generation unit and transformed into a multi-phase clock. Inputted random data are received by the sampling unit and sampled by the multi-phase clock. Each data bit of the random data is divided into several sampling intervals according to a phase number of the multi-phase clock. The digital logic unit analyzes sampling values logically, judges the corresponding sampling interval of each sampling value and outputs signals for indicating that a frequency of the random data is higher or lower than the frequency of the single-phase clock based on differences in the corresponding sampling intervals of the sampling values at two adjacent times. A method for detecting frequencies is further provided.Type: GrantFiled: August 22, 2011Date of Patent: August 12, 2014Assignee: IPGoal Microelectronics (SiChuan) Co., Ltd.Inventors: Yong Quan, Guosheng Wu
