Abstract:
The present invention is a novel and improved method and system for performing the pilot frequency tracking operation for coherent demodulation in a system employing a gated pilot signal. In particular, the present invention describes a method and apparatus in which two frequency tracking loops operate in parallel. The first frequency tracking loop performs its tracking operation based on the hypothesis that the received pilot is continuous throughout the frame's duration. The second frequency tracking loop performs the tracking operation based on the hypothesis that the received pilot is discontinuous and is only present for a portion of the frame's duration.
Abstract:
A back up power embodied non-volatile memory device including a connection port, a power supply unit and a memory system. A host machine provides data and power to the connection port through an external bus. The memory system holds the data received from the connection port temporarily and transfers the data to a non-volatile memory unit inside the memory system. The power supply unit provides necessary power to complete the transfer of temporarily stored data inside the memory system to the non-volatile memory unit to become readable data when host power suddenly fails.
Abstract:
A system and method for determining the data rate of a frame of data at a receiver of a variable rate communications system. A vocoder at a transmitter encodes a frame of data at one of the rates of a predetermined set of rates. The data rate is dependent on the speech activity during the time frame of the data. The data frame is also formatted with overhead bits, including bits for error detection and detection. At the receiver, the data rate for the frame is determined based on hypothesis testing. Because the data rate is based on speech activity, a hypothesis test may be designed based on the statistics of speech activity. The received data frame is first decoded into information bits at the most probable rate as provided by the hypothesis test. Error metrics are generated for the decoded information bits. If the error metrics indicate that the information bits are of good quality, then the information bits are presented to a vocoder at the receiver to be processed for interface with the user. If the error metrics indicate that the information bits have not been properly decoded, then the received data frame is decoded at the other rates of the set of rates until the actual data rate is determined.
Abstract:
A lighting device is composed of a case, a driving device, a power source contacting device, a power source rotary device, an actuating arm, and at least a light ball. When the power source is turned on to light up the lighting device, the motor of the driving device starts to rotate the rotary device and the actuating arm synchronously. Accordingly, the lighting ball is rotated horizontally. In addition, a gear disk of the light ball rolls along a gear ring on the case such that the light ball can rotate vertically as well.
Abstract:
Systems and methods for simultaneously communicating over multiple air interfaces using a single transceiver are described herein. An input is received at a transceiver. The input has a first signal encoded using a first radio technology and a second signal encoded using a second radio technology. The input is converted from an analog domain to a digital domain. The input is separated into the first signal and the second signal in the digital domain.

A touch display panel includes a display panel and a touch sensing unit. The touch sensing unit includes first sensing series, and second sensing series. Each of the first sensing series includes a plurality of first transparent sensing pads disposed along a first direction, and a plurality of non-transparent bridge lines disposed along the first direction. Each of the non-transparent bridge lines is disposed between two adjacent first transparent sensing pads, overlapping with two adjacent first transparent sensing pads, and electrically connected to two adjacent first transparent sensing pads. The line width of each non-transparent bridge line is substantially between 0.5 micrometers and 10 micrometers, and the reduction of aperture ratio in a pixel region of the touch display panel caused by the non-transparent bridge lines is substantially between 0.1% and 5%.
Abstract:
A mobile station may include a standard transmit pulse-shaping filter, a standard receive pulse-shaping filter, a narrower transmit pulse-shaping filter, and a narrower receive pulse-shaping filter. A femtocell base station may include a narrower transmit pulse-shaping filter and a narrower receive pulse-shaping filter. The mobile station may utilize the narrower transmit pulse-shaping filter for transmitting uplink signals and the narrower receive pulse-shaping filter for receiving downlink signals when it is receiving service from the femtocell base station. The mobile station may utilize the standard transmit pulse-shaping filter for transmitting uplink signals and the standard receive pulse-shaping filter for receiving downlink signals when it is receiving service from a macrocell base station.
