  • Patent number: 8965262
    Abstract: When filler particles are added to a surface layer of a fixing member in order to enhance a toner releasing property, if the filler particles are randomly oriented, chemical affinity between the surface layer of the fixing member and toner is enhanced and a sufficient effect cannot be accomplished. Therefore, whisker-shaped filler particles are added to the surface layer of the fixing member, and the filler particles are oriented to approximately follow a rotation direction of the fixing member.

  • Patent number: 8965273
    Abstract: Disclosed are a repeater for receiving signals from a base station in a wireless communication system, and a signal receiving method. The base station reports, to each repeater, information on the aggregation level of a relay-control channel element (R-CCE) of a relay-physical downlink control channel (R-PDCCH) via an explicit signaling method or implicit signaling method. In the event the base station reports via an explicit signaling method, the repeater receives, from the base station, information on the aggregation level of R-CCE which is a transmission unit of R-PDCCH, wherein the information contains control information for the repeater. Then, the repeater decodes an R-PDCCH region on an R-CCE aggregation level basis in accordance with the received R-CCE aggregation level information.

  • Patent number: 8965285
    Abstract: A system for expediting wireless connection establishment between wireless-enabled apparatuses. In at least one example implementation an apparatus may transmit discovery messages for discovering other apparatuses. The apparatus may receive one or more messages responding to the discovery message, and may determine whether any of the received responses satisfy a predetermined response criteria. If the apparatus determines that any of the received messages satisfy the response criteria, wireless connection establishment may be expedited between the apparatus and a source apparatus for each of the received messages that satisfy the response criteria. In an alternative scenario where a touch mode may be active in an apparatus that receives a message from at least one other apparatus, the apparatus may determine whether the message satisfies a predetermined criteria. If the message is determined to satisfy the criteria, the apparatus may expedite wireless connection establishment to the other apparatus.

    Abstract: Systems and methods for suppressing interference from a data signal received at a receiving device, where the receiving device has two or more receive antennas, are provided. Characteristics of a channel are estimated, the channel being a channel through which the data signal was transmitted by a transmitting device to the receiving device. A spatial correlation of interference and noise received at the two or more receive antennas of the receiving device is determined based on the estimated characteristics of the channel. The spatial correlation indicates how the interference and noise received at a particular one of the receive antennas is related to the interference and noise received at another one of the receive antennas. The spatial correlation of the interference and noise is used to suppress interference and noise from the data signal received at the receiving device.

  • Patent number: 8965300
    Abstract: A method for testing transmission modes of a wireless communication device. According to the method, a switching range is determined in a parameter space in a test device. The parameter of the parameter space describes the quality of transmission and influences a recommendation for a transmission mode to be adjusted in a device to be tested. The switching range is a subspace of the parameter space and contains at least one switching limit for the recommendation for the subsequent transmission mode to be adjusted. In a further step, random parameter points from the switching range are generated depending on a probability distribution which is defined for the switching range. A signal is generated for every parameter point and has a transmission mode determined by the parameter point and is transmitted to the device to be tested.

  • Patent number: 8965301
    Abstract: A method includes transmitting, by a first node, a first carrier signal and receiving, from a second node, which receives the first carrier signal, a second carrier signal. The first node measures first and second values of a first phase, the first value assigned to a first frequency of the second carrier signal and the second value assigned to a second frequency of the second carrier signal. The first and second frequencies have a frequency difference. A third value of a second phase is assigned to a third frequency of the first carrier signal, and a fourth value of the second phase is assigned to a fourth frequency of the first carrier signal. The third and fourth frequencies have the frequency difference. A distance between the first and second nodes is determined from the frequency difference from the first and second values and from the third and fourth values.

  • Patent number: 8965303
    Abstract: An electronic device includes a main antenna and a diversity antenna. The diversity antenna includes a first portion configured to enable a transceiver to receive a signal in a first low-band frequency of four frequency bands. A second portion enables the transceiver to receive a signal in first and second high-band frequencies. A third portion is RF coupled to the first portion when the third portion is connected to ground. The third portion tunes the first portion such that the transceiver receives a signal in a second low-band frequency. A switch is connected between the third portion and the ground. When the switch is open, the first portion enables the transceiver to receive the signal in the first low-band frequency. When the switch is closed, the third portion tunes the first portion to enable the transceiver to receive the signal in the second low-band frequency.

  • Patent number: 8965309
    Abstract: Aspects of a method and system for calibrating a power amplifier are provided. In this regard, one or more reference signals may be generated and may be utilized to characterize a signal strength indicator (SSI). Additionally, measurements of power output by a power amplifier by the SSI may be corrected based on the characterization of the SSI. Accordingly, the power amplifier may be adjusted based on the corrected measurements. The reference signals utilized to characterize the SSI may be limited to a determined range. In this regard, signal strength of the reference signals, as measured by the SSI, may be compared to the expected signal strength in order to characterize the SSI. The SSI may be characterized over a range of frequencies and/or signal strengths. Similarly the power amplifier may be adjusted over a range of frequencies and/or signal strengths.
