Abstract: A scanning device scans both sides of a document. The document is fed between a first image sensor module and a second image sensor module. The second image sensor module is moved with respect to the first image sensor module so that a separation distance between the second image sensor module and the first image sensor module is based on a thickness of the document. A first side of the document is scanned using a first scan line located in the first image sensor module. A second side of the document is scanned using a second scan line located in the second image sensor module. When the document is fed between the first image sensor module and the second image sensor module, the document does not reach the first scan line and the second scan line simultaneously.

Abstract: Systems, methods, and software are provided for facilitating data searching over a network. For example, in one implementation, a first component may be adapted to communicate with a user via a user device over the network. A second component may be adapted to receive a search request from the user via the user device over the network, process the search request by identifying zero or more contexts related to the user based on information that may be passed with the search request or via other sources, and provide zero or more search results in response to the search request. A database may be adapted to store information, including contextual information, related to the user. The second component may select information from the database related to zero or more contexts in order to provide zero or more search results to the user.

Abstract: The present invention relates to scanning multi-sided documents. The scanner device scans the multi-sided document one side at a time. The image of each side is tiled vertically or horizontally to form a composite image, which is transferred from the source to the application based on the TWAIN protocol. The source is TWAIN compliant, and it allows any TWAIN application to scan and process multi-sided cards as a single composite image. The source provides a TWAIN user interface which allows the user to select scanning parameters and options. The invention also provides a method of implementing a TWAIN source to use the document sensor on a scanner to efficiently scan single or multi-sided cards based on the TWAIN protocol. The source checks the status of the document sensor when the TWAIN user interface is displayed, and automatically starts scanning when a document is detected by the sensor.

Abstract: A loader stores and loads round objects is presented. The loader includes a screw and a drive tube. The screw has a helical groove. The helical groove winds in a first direction. The drive tube has multiple helical grooves on an inner surface of the drive tube. The multiple helical grooves wind in a second direction. The second direction is counter to the first direction. The screw is located within a center of the drive tube along a length of the drive tube so that round objects loaded within the drive tube are each within the helical groove of the screw and within one of the multiple helical grooves on the inner surface of the drive tube. When the drive tube rotates with respect to the screw, round objects within the drive tube are constrained to travel along the helical groove of the screw and along one of the multiple helical grooves on the inner surface of the drive tube.

Abstract: The process of dividing sentences into phrases is automated. The sentence is divided into sub-sentences using statistical analysis. Then, the sub-sentences are into phrases, using statistical analysis. For example, for each pair of adjacent words in the sentence a metric is calculated which represents a strength of disconnection between the adjacent words. The sentence is divided into sub-sentences at locations in the sentence where the metric exceeds a first threshold.

Abstract: A first device detects whether a second device implements full duplex communication. When the first device begins receiving a network packet from the second device, the first device transmits a jam signal to the second device. When transmission of the network packet from the second device to the first device has been completed, the first device determines whether a check value within the network packet is valid. When the check value is valid, the first device recognizes that the second device implements full duplex communication. When the check value is not valid, the first device recognizes that the second device does not implement full duplex communication.

Abstract: A filter system includes a low pass filter, a first summer circuit, a second low pass filter and a second summer circuit. The first low pass filter includes an input, an output, a storage means, a switching means and a control means. An input signal is placed on the input. An output signal is generated on the output. The storage means provides storage of a signal sample over time. The switching means, when closed, electrically couples the input to the first end of the storage means. The switching means, when open electrically isolates the input from the first end of the storage means. The control means controls the switching means. The control means generates a switching control signal. The switching control signal has a sampling frequency. A maximum cutoff frequency of the low pass filter is dependent on a value of a capacitance provided by the storage means, the sampling frequency, and a pulse width of the switching control signal.

Abstract: A built-in-self-test circuit aids in testing a phase locked loop circuit. The phased locked loop has a plurality of frequency multipliers. The built-in-self-test circuit includes a frequency divider and a multiplexer. The frequency divider has a plurality of divide-by-counters. For each frequency multiplier within the plurality of frequency multipliers there is a corresponding divide-by-counter. A ratio of a multiplier for each frequency multiplier to a divider of its corresponding divide-by-counter is a constant for all frequency multipliers and corresponding divide-by-counters. When a frequency multiplier within the plurality of frequency multipliers is selected, the multiplexer selects its corresponding divide-by-counter to produce a test output clock.

Abstract: In order to increase the versatility with which incoming phone calls, are handled, a plurality of outgoing messages are stored. A first caller identification is associated with a first outgoing message from the plurality of outgoing messages.

Abstract: A multi-platen chemical-mechanical polishing system is used to polish a wafer. The wafer is polished at a first station. During polishing, an endpoint is detected. The endpoint is detected by generating optical radiation by a first light source. The first optical radiation travels through a translucent area in a surface of a first platen and travels through a first polishing pad. After being reflected by the wafer, the optical radiation returns through the first polishing pad through the translucent window to a first optical radiation detector. The first polishing pad has a uniform surface in that no part of the surface of the first polishing pad includes transparent material through which non-scattered optical radiation originating from the first light source can pass and be detected by the first optical radiation detector. Optical radiation that travels through the first polishing pad and is detected by the first optical radiation detector is haze scattered by inclusions within the first polishing pad.

Abstract: A primary layer deposited over a secondary layer is planarized. A chemical mechanical polishing process is performed using a slurry which targets the primary layer. Then, chemical etching is performed using a chemical wet etchant which targets the secondary layer. The method is used, for example, when making connections to a lower layer through an insulating layer. Plug holes are formed through the insulating layer to the lower layer. Then the secondary layer is deposited. The secondary layer acts as a barrier layer or a glue layer.

During re-oxidation, nitrogen-based gas is introduced to nitridize re-oxidized portions of the gate oxide layer.

Abstract: A circuit monitor performance of an integrated circuit. The circuit includes a clock signal and a phase delay detection circuit. The clock signal is used by the integrated circuit to generate an output signal on an output pin of the integrated circuit. The phase delay detection circuit detects relative phase difference between the clock signal and the output signal on the output pin of the integrated circuit. The phase delay detection circuit includes a digital signal generator and an integrator. The digital signal generator is connected to an output pin of the integrated circuit. The digital signal generator generates a digital signal. Changes in phase delay between the output signal on the output pin of the integrated circuit and the clock signal used by the integrated circuit are encoded in a duty cycle of the digital signal generated by the digital signal generator. The integrator is connected to the digital signal generator and integrates the digital signal to produce an integrated signal.

Abstract: Power-on-reset logic is included within an integrated circuit. The power-on-reset logic includes a power-on-reset cell. The power-on-reset cell causes a reset signal to be issued upon a power signal being connected to the integrated circuit. The power-on-reset cell includes a power down input connected to a power-down line. When a power-down signal is placed on the power-down line, the power-on-reset cell is inactivated so that the power-on-reset cell does not cause the reset signal to be issued upon the power signal being connected to the integrated circuit. The power-on-reset logic also includes a logic block connected to the power-down line and to a system clock. The logic block issues a reset when the power-down signal is placed on the power-down line and the system clock is active. For example, the logic block is a delay (D) flip-flop having a D input connected to the power down line and a clock input connected to the system clock.
