摘要： Disclosed is a method of generating a transformation matrix that transforms the data from a first coordination system of a first image sensor to a second coordination of a second image sensor. The method starts by generating an initial transformation matrix based on a two dimensional image data representation of an area 1002. A refined matrix is generated from the initial matrix and a three dimensional image data representation of the area, by aligning depth values of the 3D image data according to the initial matrix 1004, extracting overlapping points in the aligned depth values1008, discarding non-overlapping points in the aligned depth values 1010, and refining the initial matrix according to the overlapping points 1012. The refining may be based on offsets between the overlapping points, the refining of th initial matrix according to the overlapping points includes generating multipliers to apply to the initial matrix based on the offsets between the overlapping points.

摘要： A user moves about a venue, and operates a mobile reader to read a product tag in a read zone of the mobile reader. An identifier, such as a user identity badge, is associated with the user to identify the user. A sensing system is deployed in the venue for sensing the location of the identifier. A host server associates the mobile reader with the identifier of the user operating the mobile reader, and determines a location of the product tag in the venue based on the read zone and the location of the identifier.

摘要： A distance to a target to be read by image capture over a range of working distances is determined by directing an aiming light spot (102, fig 5) along an aiming axis (48, fig 2) to the target and capturing a first image of the target containing the aiming light spot, and by capturing a second image of the target without the aiming light spot. Each image is captured in a frame over a field of view having an imaging axis (24, 36, fig 2) offset from the aiming axis. An image pre-processor compares first image data from the first image with second image data from the second image over a common fractional region of both frames to obtain a position of the aiming light spot in the first image, and determines the distance to the target based on the position of the aiming light spot in the first image.

摘要： Disclosed is a method of determining a reference sensor of a plurality of sensors toward which a vehicle is moving based on image data generating by the sensors. The method starts by identifying features in the images, identifying matching features in the images based on the identified features. The matching features are used to generate a direction vote which is indicative of the direction of movement of a vehicle. The result of the vote is used to select one of the image sensors as a reference sensor. Also disclosed is a method for generating a transformation matrix for transforming information from a first coordinate system of a first image sensor to a second coordinate system image sensor. The method starts by generating an initial transformation matrix based on 2D image data representing an area and refining the transformation using a 3D image data of the area. Next the depth values of the 3D image data according to the initial transformation matrix, extracting and discarding overlapping points in the aligned depth values, and refining the matrix according to the overlapping points.

摘要： Un système (10) de lecture d'étiquette d'identification radiofréquence (RFID) et un procédé de détermination avec précision et rapidement, en temps réel, des gisements vrais d'étiquettes RFID associées à des articles dans une zone contrôlée. Les faisceaux d'émission et de réception principaux sont orientés sur la zone, et de multiples faisceaux de réception secondaires sont orientés sensiblement simultanément vers une pluralité de gisements dans la zone. L'intensité de signal la plus élevée des signaux de réception secondaires provenant des faisceaux de réception secondaires détermine un gisement d'étiquette approximatif de chaque étiquette. Deux faisceaux de réception secondaires des côtés opposés du gisement d'étiquette approximatif en élévation sont sélectionnés pour obtenir une paire de signaux décalés d'élévation, et deux faisceaux de réception secondaires des côtés opposés du gisement d'étiquette approximatif en azimut sont sélectionnés pour obtenir une paire de signaux décalés d'azimut. Les signaux décalés d'élévation et les signaux décalés d'azimut sont traités pour déterminer un gisement vrai pour chaque étiquette en temps réel.

The client device includes a memory and a radio coupled to at least one processor. The at least one processor executes in the memory a first client Wireless Local Area Network (WLAN) stack having a plurality of layers configured to couple the radio to a WLAN. The at least one processor also executes in the memory a second client WLAN stack emulating the plurality of layers of the first client WLAN stack. The at least one processor is configured to receive, at the second client WLAN stack, data from the plurality of layers of the first client WLAN stack and analyze a predetermined set of WLAN parameters of the client device based on the data received from the plurality of layers of the first client WLAN stack.

摘要： A method and apparatus for a co-located Radio Frequency Identification (RFID) device and ultrasonic device includes an RFID reader loop antenna element oriented parallel to a reflector panel. An ultrasonic emitter is disposed through an aperture in the reflector panel with a horn that extends through the loop element. The horn can serve as a mounting structure for the antenna element. A diameter of the aperture is less than one-quarter wavelength of an operating frequency of the RFID reader loop antenna element. The aperture is located in the reflector panel near a minimum E-field area of the RFID reader loop antenna element.
