  • Patent number: 8694250
    Abstract: Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple Global Navigation Satellite Systems (GNSS), where at least one GNSS is Frequency Division Multiple Access (FDMA). Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities.

  • Publication number: 20140064165
    Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

  • Publication number: 20140064160
    Abstract: Synchronizing uplink and downlink transmissions by a wireless user equipment (UE) device. A connection with a network may be established via a wireless link with a cell. The UE may operate in an active state during first periods of time in which uplink or downlink communications may be performed between the UE and the network. The UE may operate in a reduced-power state during second periods of time in which uplink and downlink communications are not performed. The first periods of time may alternate with the second periods of time in a repeating manner. Uplink data generated by the UE may be buffered during second periods of time and transmitted during first periods of time. Buffering uplink data in this manner may prevent the UE from immediately transitioning from the reduced-power state to the active state to transmit uplink data, which may conserve battery of the UE.

  • Publication number: 20140016567
    Abstract: A technique for securing transmit opening helps enhance the operation of a station that employs the technique. The technique may facilitate low latency response to a protocol data requester, for instance. In one aspect, the technique provides a way for the protocol data responder to hold its transmit opening to transmit the protocol response data to the protocol data requester. The technique may allow the protocol data responder to hold the transmit opening until the protocol response data is ready and available for the protocol data responder to send.

    Abstract: A stereoscopic image display device includes a display panel, a temporal division plate and a lenticular lens. The display panel includes a gate line, a data line, and a unit pixel of a horizontal pixel structure in which a long side is parallel with the first direction and a short side is parallel with the second direction. The display panel displays a 2D image based on an image control signal. The temporal division plate includes a plurality of shutters disposed on the display panel extending in the second direction. The temporal division plate opens and closes m shutters corresponding to each unit pixel, in a sequence, ‘m’ being a natural number no less than 2). The lenticular lens is disposed on the temporal division plate to convert the 2D image passing the temporal division plate into a 3D image.

  • Publication number: 20130215745
    Abstract: Dynamic buffer management for wireless communication systems facilitates enhanced throughput. The dynamic buffer management reduces buffer allocation for the current service period near the end of the current service period, and allocates the freed buffer space to one or more subsequent service periods before they begin. As a result, the host may begin to transfer data for those subsequent service periods in advance, so that data is immediately available to send when the subsequent service periods begin.

  • Publication number: 20130034061
    Abstract: A responder endpoint establishes a reverse direction communication channel from the responder to an initiator. To that end, the responder endpoint receives a reverse direction grant indicator and determines when primary data is not ready to be sent to the initiator. In response, the responder transmits to the initiator, within a predetermined response time for establishing the reverse direction communication channel, a continuation frame comprising a continuation indicator that indicates that reverse direction communication channel should persist. In one implementation, the continuation frame includes at least one control field including the continuation indicator, but no data payload field.
