Abstract: Fast macrodiversity switching (FMS) of channels that employ interleaving. The fast macrodiversity switching dynamically switches radio links used for traffic and control channels for a mobile station among a number of base transceiver stations (BTS) without switching the radio resource, using the same frequency and time slot combination (TDMA) in an environment where interleaving is occurring. The fast macrodiversity switching of channels and interleave processing is under control of an interleave manager which is distributed among zone managers. The control by the host and assistant zone managers includes switching down-link signals to and up-link signals from mobile stations among base transceiver stations which include broadcast channels (non-switched) and dedicated (switched) channels that employ interleaving. The dedicated channels are switched as frequently as a signal switch time which can be the frame rate of the up-link signals.

The present invention can also extend to a method for selecting a scan area by a user and a scanner with a feature of automatically identifying a scan area.

Abstract: A multi-channel RF receiver uses an image rejection mixer (e.g. double quadrature mixer) in the IF down conversion stage for image side band rejection (whereby use of an IF narrow band filter for image rejection may be omitted if desired) and comprises a simplified frequency synthesizer which generates both a “wandering” IF oscillator frequency and an RF oscillator frequency for the up/down conversion stages (being, for down conversion, from RF to IF and from IF to base band. The IF used for a particular RF carrier (channel) is selected so as to be both an integer (N) sub-harmonic of that RF carrier and within the operating frequency band of the image rejection mixer. Advantageously, the synthesizer comprises only one loop and one VCO, wherein the IF oscillator signal is produced from the RF oscillator signal by means of a frequency divider.

Abstract: A parallel processing architecture comprising a cluster of embedded processors that share a common code distribution bus. Pages or blocks of code are concurrently loaded into respective program memories of some or all of these processors (typically all processors assigned to a particular task) over the code distribution bus, and are executed in parallel by these processors. A task control processor determines when all of the processors assigned to a particular task have finished executing the current code page, and then loads a new code page (e.g., the next sequential code page within a task) into the program memories of these processors for execution. The processors within the cluster preferably share a common memory (1 per cluster) that is used to receive data inputs from, and to provide data outputs to, a higher level processor. Multiple interconnected clusters may be integrated within a common integrated circuit device.

Then, the colors of the four corners of the preliminary range are identified. Finally, the precise position of the document is determined by color identification, approaching from the rim of the preliminary range toward the the document.

Abstract: A method and apparatus for monitoring of a semiconductor light source utilizing a beamsplitter within a photonic package is described, wherein the photonic package comprises a housing, a semiconductor light source disposed within the housing. The semiconductor light source has a first light beam output having data encoded thereon. A beam splitter cube (BSC) also disposed inside the housing to create a first split output of the first light beam output. The BSC has a light beam splitting characteristic that negatively impacts the encoding of the data in the first light beam within a predetermined limited threshold. A photodetector is disposed inside the housing to receive the first split output. The photodetector is adapted to determine properties of the first split output notwithstanding that the first split output is created in the limited impact manner.

Abstract: A method and a system for increasing scanning speed are provided. The method may include determining a transmission rate of a transit interface, scanning an original to generate an image data, and adjusting a cycle time of the image data to change a data generating rate responsive to the transmission rate of the transit interface. One aspect of the present disclosure may be by adjusting the cycle time of a state machine to change the data generating rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the cycle time of the state machine may be adjusted to produce the data at a rate that prevents the smearing process. Thus, the possibility of memory buffer full may be reduced, which may lead to the reduction in start-stop processes and therefore the overall scanning speed may be increased without necessarily requiring the increase in size of a memory buffer.

Abstract: A method for activating a packet data protocol context in a wireless telecommunication system comprising at least one terminal and at least one network element. The network element is arranged to deliver packets between the wireless telecommunication system and other packet data networks. Direction-specific service conditions are stored in the telecommunication system for packets received by the network element and designated to at least one terminal. The stored direction-specific service conditions determine what kind of service is provided for packets received from different directions. The direction of a received packet is determined and the direction-specific service conditions relating to the determined direction of the packet are checked. The packet data protocol context is activated according to the direction-specific service conditions.

Abstract: An accelerative noise filtering method for image data is provided. The present invention includes selecting four neighboring pixels around a target pixel in a pattern of a cross shape or X shape, and calculating the absolute value of a difference between the target pixel and each of the four neighboring pixels. When the absolute value of the difference of the neighboring pixel is not larger than a standard deviation, a binary value of a bit corresponding to the neighboring pixel is set “1”. When the absolute value of the difference of the neighboring pixel is larger than a standard deviation, a binary value of a bit corresponding to the neighboring pixel is set “0”. Consequently, a 4-bit mapping table including the binary values of the four neighboring pixels is obtained. Then, a new pixel value for replacing the target pixel value is calculated based on a calculation derived from the 4-bit mapping table.
