Abstract:
A method of and system for returning a consumer product in a retail environment and preventing or reducing employee theft of returned merchandise in retail store environments and providing greater accountability for returned merchandise in retail store environments. The method comprises providing an image capturing and processing system at the retail environment, including a system housing having an imaging window and generating and projecting a field of view through the imaging window, and into a 3D imaging volume definable relative to the imaging window. The digital image capturing and processing system produces one or more digital images of consumer goods (i.e. products) passing within the 3D imaging volume. Identification (ID) data for the consumer returning the purchased goods is entered into a host system connected to the digital image capturing and processing system, as well as identification data for the employee to whom the goods are being returned. The digital image capturing engine captures one or more digital images of returned products and these digital images are provided to the host system. The host system generates an electronic document containing identification data for the customer and employee along with the one or more digital images of the returned product or merchandise. The electronic document is then transmitted from the host system to a database server associated with the retail store environment, for storage and subsequent processing. By virtue of the present invention, it is now possible to prevent or reduce employee theft of returned merchandise in retail store environments and provide greater accountability for returned merchandise in such store environments.

Abstract:
A digital image capturing and processing system for automatically recognizing objects in a POS environment. The system includes a system housing having an imaging window; illumination and imaging stations for generating and projecting illumination and imaging planes or zones through the imaging window, and into a 3D imaging volume definable relative to the imaging window, for digital imaging an object passing through the 3D imaging volume, and generating digital linear images of the object as the object intersects the illumination and imaging planes or zones during system operation. A digital image processor processes the digital images and automatically recognizes the object, such as produce and fruit, graphically represented by the digital images.
Abstract:
A packet-based, hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. The network accommodates real time voice transmission both through dedicated, scheduled bandwidth and through a packet-based routing within the confines and constraints of a data network. Conversion and call processing circuitry is also disclosed which enables access devices and personal computers to adapt voice information between analog voice stream and digital voice packet formats as proves necessary. Routing pathways include wireless spanning tree networks, wide area networks, telephone switching networks, internet, etc., in a manner virtually transparent to the user. A voice session and associate call setup simulates that of conventional telephone switching network, providing well-understood functionality common to any mobile, remote or stationary terminal, phone, computer, etc.

Abstract:
An image capture device, method and system where pixel data captured by the image capture device is read from the device in logical pixel rows. A logical pixel row is an externally defined row of pixels where the pixels that comprise the logical pixel row are read from parts of multiple physical rows of pixels. Logical pixel rows are at an angle to the physical rows of pixels that comprise the pixel array of the image capture device.

Abstract:
A digital image capturing and processing system for illuminating objects using automatic object detection and spectral-mixing illumination technique. The system comprises an area-type illumination and imaging module for projecting a coextensive area-type illumination and imaging field (i.e. zone) into a 3D imaging volume during object illumination and imaging operations. The area-type illumination and imaging module includes a spectral-mixing based illumination subsystem for producing a first field of visible illumination from an array of visible LEDs, and producing a second field of invisible illumination from an array of infrared (IR) LEDs, wherein the first and second fields of illumination spatially overlap and intermix with each other and produce a composite illumination field that is at least substantially coextensive with the FOV of the image sensing array. An automatic object detection subsystem automatically detects an object moving through the 3D imaging volume, while an illumination control subsystem controls the relative power ratio (VIS/IR) of visible illumination and invisible illumination during system operations so as to achieve sufficient image contrast in captured digital images to ensure satisfactory image processing.
