Abstract:
A wireless communication system base station, and a remote radio head (RRH) and a computer-implemented synchronization method for the wireless communication system base station. The RRH is communicably coupled to a baseband unit (BBU) of the wireless communication system base station through a network, and the BBU processes and transmits downlink data to the RRH. The RRH includes: a time-delay measurement unit for measuring a time-delay for the downlink data to arrive at the RRH from the BBU; and a time-delay notification unit for notifying from the RRH to the BBU of time-delay data on the time-delay measured by the time-delay measurement unit, wherein the time-delay data is used to advance the starting time for the BBU to process and transmit the downlink data by an amount of time obtained based on the time-delay data.
Abstract:
A liftable puller device includes a holder, a puller assembly located on the holder, a first frame coupled with the holder and a second frame coupled with the puller assembly. The puller assembly is installed on the holder via the first frame and second frame, and includes a plurality of grippers to grip a wheel. The first frame has a first main retaining zone located on the top end thereof, two first sub retaining zones relative to the first main retaining zone and a first auxiliary retaining zone between the first main retaining zone and one first sub retaining zone. By providing the first auxiliary retaining zone, only a small range of movement is needed to complete switch between a two-gripper and a multi-gripper puller device.

Abstract:
A system and method for detecting errors in high-speed asymmetric interfaces are described. Embodiments include transmitting digital data between a first system component and a second system component over a bidirectional interface, wherein the first component is significantly more intelligent than the second component. The first component controls many operations of the second component, including receiving a signature from the second component over an existing line of the interface. The signature received is compared to a signature stored by the first component. Both signatures correspond to a transaction over the interface. Based on the comparison, the first component determines whether the transaction was successful, and directs the second component as necessary.

A wireless communication transceiver and a mode switch device thereof. The transceiver includes: a first band transmission path; a first band reception path; a second band transmission path; a second band reception path; a path switch and a control unit. In a dual band time division duplexing mode, the control unit controls the path switch so that the path switch connects a received radio frequency signal from an antenna to the first band reception path, and connects a transmitted radio frequency signal from the second band transmission path to the antenna in an odd cycle or an even cycle; and controls the path switch so that the path switch connects a received radio frequency signal from the antenna to the second band reception path, and connects a transmitted radio frequency signal from the first band transmission path to the antenna in another odd cycle or another even cycle.
Abstract:
A panel light frame is revealed. Each of two ends of a second frame strip is inserted between a pressing end surface and a top end surface of a first frame strip. A front edge of the second frame strip is leaning against the pressing end surface of the first frame strip and an outer end surface of the second frame strip is leaning against the top end surface of the first strip. Thus connection end surfaces of the first and the second frame strip are connected to and positioned by each other. Thereby light from light emitting modules is shielded by the connection end surfaces for preventing light leakage. Moreover, the first and the second frame strips are against, supported and positioned by each other and this makes the connection of the frame strips more convenient. The panel light frame has higher practical value.
Abstract:
A supporting stand for multiple screens includes a frame and a movable module. The frame is disposed on a working surface and having a track module. The track module has two tracks, where one of the tracks has a restricting surface extended along a first direction, and the other track has a restricting surface extended along a second direction. The movable module has a pair of movable units for supporting a pair of screens and movably engaging the tracks. Each movable unit has a sliding component having a contacting surface. The shape of the two contacting surfaces conforms in shape to the two restricting surfaces. The two contacting surfaces respectively contact the two restricting surfaces for enabling the two contacting surfaces to be movable respectively along the first direction and the second direction.
Abstract:
The present invention provides a high-side driver circuit including a power transistor, the first transistor, the second transistor, the second capacitor, the second diode, a start-up circuit. The start-up circuit is coupled between a resistor and the second capacitor to complete a gate driving circuit. And, the aforementioned resistor can either be the gate resistance of the power transistor or an external resistor. The design of start-up circuit enables the functionality of the bootstrap capacitor of being charged to a designate voltage level. Thus, the depletion-mode transistor can be controlled to turn on/off without a floating voltage source or a negative voltage source.
