Abstract: A display device including a gate driver, a data driver and a plurality of sub-pixels is disclosed. The gate driver sequentially asserts a first scan signal and a second scan signal. The data driver provides a first data signal and a second data signal. When the first scan signal is asserted, the first scan signal and the first data signal respond with a first response signal.

Abstract: This invention provides a color passive matrix bistable liquid crystal display system, in which one respective scan line corresponds to sub-pixels of same color and neighboring scan lines correspond to sub-pixels of different colors. The scan lines are grouped in accordance with the colors of the sub-pixels corresponding thereto such that different scan driving voltages can be provided to the sub-pixels of different colors when the scan lines are scanned. By way of the arrangement of the sub-pixels, different scan driving voltages are switched to the respective scan lines in accordance with the colors of the sub-pixels corresponding thereto. As a result, a demand that the sub-pixels of different colors require different scan driving voltages is satisfied. The image quality is improved.

Abstract: A method and system for predicting a signal power to interference metric for a communication channel in a coverage area of a phase sweep diversity communication system are provided. In the method, a signal power to interference metric for the communication channel is predicted based on a sweep frequency for transmissions in the coverage area. The signal power to interference metric predicted may be a carrier-to-interference ratio or a signal-to-noise plus interference ratio.

Abstract: A display unit comprises a display medium which is writable, erasable and displayable of an image and a rotatable writehead with a number of loop conductors parallel with each other. The display medium is capable of maintaining a written image without power. In operating of writing on the display medium, the loop conductors apply an electric field to a particular area of the display medium, changing the optical state of the particular area of the display medium. In operating of writing on the display medium, there is no relative motion between the display medium and the writehead.

Abstract: In a wireless communication system, unique methods are presented to dynamically assign channel codes of different lengths in a manner to maintain orthogonality among assigned channels. In one embodiment, channel codes that require relatively long-lengths are assigned from a first end of a list of unassigned channel codes and channel codes of a shorter length are assigned from an opposing end of a list of unassigned channel codes. Assignment of a shorter length code sequence is made if the longer-length channel codes that depend from the proposed shorter length code sequence are available. In another embodiment, the availability of short length channel codes is derived directly from the availability of the longest length channel codes. In this embodiment, a group of longest-length channel codes that contain a common shorter-length code of the desired length are checked for availability. If all the codes of the group are available then the common shorter-length code may be assigned to transmission.
