摘要： An electronic device includes an enclosure for the electronic device and a duct extending from an interior to an exterior of the enclosure to exhaust airflow from the enclosure. The electronic device further includes an active noise control mechanism. The active noise control mechanism includes an internal sensor, an external sensor, and an acoustic wave generator. The internal sensor is arranged within the enclosure to sense a noise and generate an internal sensor output, and the external sensor is arranged outside of the enclosure to detect sounds and generate an external sensor output. Based on the internal sensor output and the external sensor output, the acoustic wave generator generates an acoustic wave within the duct to reduce the noise.

摘要： An apparatus for capturing images and barcodes. The apparatus has an image-sensing device and a lens having a variable-focal-length region and a substantially fixed-focal-length region. The variable-focal-length region focuses light onto a first region of the image-sensing device and the substantially fixed-focal-length region focuses light onto a second region of the image-sensing device. The variable-focal-length region varies such that different portions of that region of the lens focus objects at different distances from the lens in different areas of the first region of the image-sensing device. Thus, the device is able to focus, in the first region of the image-sensing device, objects at varying distances from the apparatus.

摘要： A video sequence control system that includes an input video frame buffer and an output video frame selection component is described. The input video frame buffer receives input video frames from a video source. The output video frame selection component determines the video frame to be output according to a scheduler that provides timing information and modulation information. The timing information includes information regarding when a video frame will be output. The modulation information varies dependent upon the frame types available to be output, wherein the available frame types include at least image frames from the input video frame buffer and functional frames, wherein the at least image frames and functional frames are output according to a pattern defined by the scheduler. In addition based on the timing information, a synchronization output signal is output corresponding to the output of the functional frame.

摘要： A method and system of tracking documents uses tags and a workflow. Initially, a workflow is developed for each document or type of documents using a state diagram. The workflow specifies a subset of one or more destinations that the document is allowed to travel and a sequence for this travel. A tag is associated with each document to enable tracking of the document as it passes the one or more readers in the various destinations. These tag readers in turn report back position information on the document to assist in locating the document. A comparison between the state diagram for the workflow and the position information gathered from the tag readers determines if the document is outside the desired workflow. An alert is generated when the document is outside the workflow and not being processed as intended.

摘要： A computer network for high-speed data communication, has a data transmission cable with a root and at least one leaf node. A signal conversion system (SCS) is attached to the root, and at least one client station is attached to a leaf node. The SCS consists of a transmitter that transmits down-stream data onto said cable in a first frequency band; and a receiver that receives data from said client stations on a second frequency band; wherein said down-stream data includes synchronization and acknowledgement signals. Each client station has a receiver that receives data on said first frequency band, and a transmitter that transmits data on a second frequency band according to synchronization signals received on said first frequency band. The computer network is controlled by a method comprising transmitting down-stream from the signal conversion system (SCS) a control signal having synchronization information on a first frequency band, receiving said control signal at client stations, transmitting up-stream from said client stations to said SCS on a second frequency band, the transmission being timed with respect to said synchronization information, and acknowledging on said first frequency band successful receipt by said SCS of said up-stream transmission. The client station's transmission packets may include requests for reserved slots on said second frequency band for subsequent transmissions, and the SCS has a scheduler operable to determine a start time for requested reserved slots, and transmits the start time for the requested reserved slots. The client stations are operable to wait to continue transmission until after waiting for the start time. Other systems and methods are disclosed.

摘要： A localization method for setting the locale of a configurable device is presented. The first portion of the localization transmits localization selections for a target locale to a configurable device. Localization selections are initially set on an interrogator device and then transmitted wirelessly using RFID or other technologies from the interrogator device to a tag coupled to the configurable device. A second portion of the localization receives localization selections for a target locale on the configurable device. A tag receives from an interrogator device one or more localization selections for the target locale on the configurable device. These localization selections are stored on the tag until the configurable device is powered-on. Device initialization causes another portion of the localization to set a target locale on a configurable device. Firmware accesses localization selections previously stored on the tag and then sets the default localization selections in the firmware for the device.
