Abstract: A system and method of using motion or spatial identification technology with a mobile RFID reader to detect whether an RFID tag is part of a forklift load or other ambulatory space such as a shopping cart receptacle, includes determining whether a tag is within a defined space and/or whether a tag is in motion relative to a mobile RFID reader. The system and method determines whether a particular RFID tag is part of a forklift load/space, has been added to or removed, is an extraneous tag, etc.

Abstract: An imaging system having a solid-state auto focusing system advantageously images broadband light reflected from an object to be imaged using a lens objective having chromatic aberration, which focuses different colors of light at different focal planes. Using the color information in the focal planes in conjunction with an object distance determined by a range finder, a luminance plane is constructed that has a focused image of the object. The system provides the focused image of the object without the use of any moving parts.

Abstract: Methods for performing a scheme that results in a refined measurement pattern within an optical grid are provided. Physically adjusting spacing of elements within an optical grid to achieve enhanced resolution is historically unfeasible, as reduction of the spacing causes light sensors of the optical grid to pick up false signals when reading light beams. Technology introduced by the present invention generates a virtual reduced spacing of the elements within the optical grid by using two signals that are slightly different. These slightly different signals can accomplish, at least, quarter-grid spacing resolution within the optical grid. Additionally, the enhanced resolution derived from the virtual reduced spacing is employed to govern movement of a motor. The motor movement is in response to one or more changes of direction such that the motor is operating in its linear range.

Keywords may be indicative one or more functionalities tested by the respective ADC device test module.

Abstract: An apparatus and method are disclosed for creating an integrated access door and switch actuator. The integrated access door and switch actuator are created from a single composite material. The composite material is flexible to allow movement, but is also durable to provide a protective covering. The integrated access door and switch actuator include a living hinge, which allows the access door to move to an open and closed position while the switch actuator is stationary in a fixed position.

Abstract: A method of operating a dimensioning system to determine dimensional information for objects is disclosed. A number of images are acquired. Objects in at least one of the acquired images are computationally identified. One object represented in the at least one of the acquired images is computationally initially selected as a candidate for processing. An indication of the initially selected object is provided to a user. At least one user input indicative of an object selected for processing is received. Dimensional data for the object indicated by the received user input is computationally determined.

Abstract: A system and method is provided for image surveillance of areas of interest for items having radio frequency identification (RFID) tags. These areas of interest are often times unmonitored due to privacy concerns. The present invention discloses an image surveillance system and method, that upon indication of an RFID tag coming within proximity of a portal system having an RFID reader, records one or more images of the area of interest, so as to capture a subject associated with the RFID tagged item moving into or through the area of interest. Such applications for embodiments of the present invention are directed to monitor items of interest in retail stores, restaurants, shipping and receiving locations, and other public areas.

Abstract: Volume dimensioning employs techniques to reduce multipath reflection or return of illumination, and hence distortion. Volume dimensioning for any given target object includes a sequence of one or more illuminations and respective detections of returned illumination. A sequence typically includes illumination with at least one initial spatial illumination pattern and with one or more refined spatial illumination patterns. Refined spatial illumination patterns are generated based on previous illumination in order to reduce distortion. The number of refined spatial illumination patterns in a sequence may be fixed, or may vary based on results of prior illumination(s) in the sequence. Refined spatial illumination patterns may avoid illuminating background areas that contribute to distortion. Sometimes, illumination with the initial spatial illumination pattern may produce sufficiently acceptable results, and refined spatial illumination patterns in the sequence omitted.

Abstract: An apparatus for use in an RFID data collection system includes an antenna portion for wirelessly exchanging signals and a memory portion for storing RFID data. A signal processing portion is coupled among the antenna portion and the memory portion. The signal processing portion is configured to receive RFID data and to at least encode or decode the received RFID data via at least one spreading code, such as a mutually orthogonal code. Other configurations are also disclosed.

Abstract: A dimensioning system can include stored data indicative of coordinate locations of each reference element in a reference image containing a pseudorandom pattern of elements. Data indicative of the coordinates of elements appearing in an acquired image of a three-dimensional space including an object can be compared to the stored data indicative of coordinate locations of each reference element. After the elements in the acquired image corresponding to the reference elements in the reference image are identified, a spatial correlation between the acquired image and the reference image can be determined. Such a numerical comparison of coordinate data reduces the computing resource requirements of graphical comparison technologies.

Abstract: Audio frames are classified as either speech, non-transient background noise, or transient noise events. Probabilities of speech or transient noise event, or other metrics may be calculated to indicate confidence in classification. Frames classified as speech or noise events are not used in updating models (e.g., spectral subtraction noise estimates, silence model, background energy estimates, signal-to-noise ratio) of non-transient background noise. Frame classification affects acceptance/rejection of recognition hypothesis. Classifications and other audio related information may be determined by circuitry in a headset, and sent (e.g., wirelessly) to a separate processor-based recognition device.

Abstract: A mobile printer comprising a printer body and a printer door is provided. The printer body typically has a recessed area that is sized to receive a media roll. The media roll typically has a void interior portion that is sized to receive one or more batteries that provide power to the mobile printer. Further, the printer door is operatively coupled to the printer body. When in an open position, the printer door typically allows for placement of a media roll from a side of the mobile printer into the recessed area. When closed, however, the media roll is typically retained in place relative to the printer body and the media from the media roll is captured for printing.

Abstract: A non-time of flight or time of arrival position location system for accurate determination of a user's location in an enclosed, indoor, or covered environment can include a number of beacons mounted in an arrangement within the environment. Each of the beacons is mounted in a known location and transmits a broadcast signal containing a unique identifier that identifies the originating beacon. A handheld electronic device including a receiver and a communicably coupled processor can receive broadcast signals from at least some of the number of beacons, iteratively determine a vector quantity corresponding to each of the received signals, and sum the resultant vector quantities to determine an updated position. The iterative process can be repeated until consecutive iterations yield an updated position that falls within a defined threshold.

Abstract: A system and method of selectively reading sensor data from a memory device is able to search the memory device for an indicator that identifies the sensor data, and read only the sensor data identified by the indicator from the memory device. In this way, interrogating devices are able to sort through sensor data stored in a network of memory devices, such as an RFID network, and report specific data of interest despite the existence of a variety of data types in the network. In some embodiments, flags are stored and associated with specific types of data, such as various sensor data, thereby allowing numerous memory devices and sensors to operate and be read efficiently in the same environment.

Abstract: Technology for standardizing an antenna design for a computing device includes an antenna element in the shape of an object that is commonly useful with multiple, different computing products. For example, in one embodiment the antenna element is a bracket for holding a stylus or other object within a stylus chamber that is associated with the computing device. The dimension and composition of the antenna remain relatively constant to provide a consistent radiation pattern requiring little or no redesign when implemented across the different products, since it may be placed at an edge of a device, by a stylus holder, or similar, common location that is a distance from a ground plane and device circuitry.
