Abstract: An HDMI cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. High-frequency loss and differential skew within a differential signal may be compensated by analog circuits embedded in the cable. These embedded circuits are tuned at production for best performance by observing the quality of the recovered analog signal. The embedded circuits are powered by a combination of power sources, both carried within the cable, and harvested from the high-speed signals themselves.

Abstract: An HDMI cable may exhibit frequency dependent signal attenuation, inter symbol interference, and inter-pair skew. A boost device integrated with the cable can compensate for such impairments of the cable. A self calibrating cable with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel.

Abstract: The device is a scoop for use with an aeration machine for collecting debris lying on the ground. The scoop including a frame and a plurality of debris pick-up plates, where each plate is mounted on the frame. Each plate also has a biasing mechanism for urging a leading edge of the plate downwardly as it is drawn across the ground.

Abstract: According to the invention, there is provided a grass treatment apparatus (an aeration device), including a support, a ground treatment implement mounted on the support, means for sensing the operating position of the ground treatment implement relative to the ground in use, means for adjusting the ground treatment implement in response to the sensed position of the ground treatment implement to maintain the ground treatment implement at a desired operating position following the contour of the ground, over which the ground treatment implement travels in use. Alternatively, the invention is an aeration device having a frame that supports reciprocating tines, and a frame orientation control for an aeration device, and includes a means for sensing or tracking the ground that is operatively connected to a means to control a ram and the associated ram.

Abstract: A cellular mobile telephone system and method in which channel assignment and telephone call routing are controlled by a central control station and in which each communications channel is separately controlled at a cell station by a radio interface module ("RIM") associated therewith. Flexibility and security from operational interruptions is provided by dynamic assignment of identical RIMs to monitoring, paging, control and communication functions at the cell station. The system is modular and may be customized to accommodate geographic and demographic considerations, while permitting expansion and modification without obsolescence. The system also includes novel, self-diagnostic testing loops and methods. A novel mobile telephone is also disclosed.
