摘要:
A method and apparatus are described for controlling the data rates for communications to and from a base station and a plurality of remote users. The usage of the communications resource whether the forward link resource (from base station to remote users) or reverse link resource (from remote users to base station) is measured. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.

A first remote vocoder receives analog voice and produces packetized vocoder data which is transmitted over a wireless link. A first local vocoder receives the packetized vocoder data from the wireless link. The first local vocoder converts the packetized data to a multibit PCM output. The first local vocoder also adds a detection code to one of the least significant bits (LSB) of the PCM output. The first local vocoder passes the PCM signal to the PSTN from the second end user. The first local vocoder also receives PCM input over the PSTN. The first local vocoder constantly monitors the least significant bit of the PCM input for a detection code indicating that a second local vocoder is connected at the receiving end. If the first local vocoder detects the detection code from the second local vocoder, it begins to substitute packetized data and a redundancy check for a second one of the LSB's of the outgoing PCM. The first local vocoder also begins to monitor the second one of the LSB's of the incoming PCM. If the redundancy check indicates that valid packetized data has been received, the first local vocoder stops converting the PCM output into packetized data and simply passes the packetized data on the second one of the LSB's to the first remote vocoder. If at any time the redundancy check fails and the detection code is not detected, the first local vocoder returns to converting the incoming PCM to packetized data. In this way, the tandem vocoding arrangement is avoided.

A method of bit depth reduction for an apparatus includes establishing a human visual response versus relative luminance, the human visual response being defined by 2M levels; determining a scanner response versus the relative luminance for at least one channel of scanner data, the scanner response being represented by N-bit per channel data, wherein N is greater than M; relating the human visual response to the scanner response; and quantizing the N-bit per channel data to M-bit per channel data according to the human visual response.

A paintball gun preferably includes an electro-pneumatic flow distribution mechanism such as a solenoid valve having a port connected to a pneumatic mechanism. For instance, the solenoid valve may include an input port receiving compressed gas from a compressed gas supply and an output port connected to the pneumatic mechanism. The solenoid valve can be enabled to direct compressed gas to and/or from the pneumatic mechanism to operate a bolt. The bolt may be coupled to the pneumatic mechanism.

The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment comprises a method for performing position location in a wireless communication system using a set of signals transmitted from a set of satellites including the steps of receiving signal samples, rotating an acquisition code by a first rotation amount yielding a rotated acquisition code, despreading said signal samples using rotated acquisition code yielding despread data, accumulating said despread data over a first duration yielding partially accumulated data, rotating said partially accumulated data by a second rotation amount yielding rotated data and accumulating said rotated data.

A cover can comprise a photoluminescent outer surface, an inner surface configured to be affixed to an indicator sign, and one or more void areas passing through the inner and outer surfaces arranged in a pattern, wherein the pattern defines a negative image in contrast to the photoluminescent outer surface, wherein the negative image corresponds to a graphic on the indicator sign such that the first graphic is visible through the void areas when the cover is affixed to the indicator sign.

A method for removing streaks from a scanned image includes performing a scanner light source OFF scan to generate a dark image having M rows of pixels and N+W columns of pixels; generating a line noise profile for the N columns of pixels of the dark image; performing a scanner light source ON scan to generate a regular image having M rows of pixels and N+W columns of pixels; processing the W columns of pixels of the regular image to detect a magnitude of the streak in the regular image; use the magnitude of the streak and the line noise profile to predict an amount of dark noise removal for each of the N columns of pixels of the regular image at the location of the streak; and subtracting the predicted amount of dark noise removal for each of the N columns of pixels from the respective N columns of pixels of the regular image.

A method for processing a duplexed document having a first side with a first image and a second side with a second image includes scanning only the first side of the document under a first imaging condition to retrieve first information relating to each of the first image and the second image; scanning only the first side of the document under a second imaging condition to retrieve second information relating to each of the first image and the second image; and determining from the first information and the second information a show-through contribution of the second image with respect to the first side of the duplexed document.
