An IP flow classification system is used in a wireless telecommunications system. The IP flow classification system groups IP flows in a packet-centric wireless point to multi-point telecommunications system. The classification system includes: a wireless base station coupled to a first data network; one or more host workstations coupled to the first data network; one or more subscriber customer premise equipment (CPE) stations in wireless communication with the wireless base station over a shared bandwidth using a packet-centric protocol; and one or more subscriber workstations coupled to each of the subscriber CPE stations over a second network; a resource allocation device optimizes end-user quality of service (QoS) and allocates shared bandwidth among the subscriber CPE stations; an analyzing and scheduling device analyzes and schedules internet protocol (IP) flow over the shared wireless bandwidth. The analyzing device includes the above IP flow classifier that classifies the IP flow. The classifier can include a device for associating a packet of an existing IP flow with the IP flow. The classifier can include a QoS grouping device that groups a packet of a new IP flow into a QoS class grouping. The QoS grouping device can include a determining device that determines and takes into account QoS class groupings for the IP flow. The QoS grouping device can include an optional differentiated services (Diff Serv) device that takes into account an optional Diff Servs field priority marking for the IP flow.

A packet-centric wireless system includes: a wireless base station communicating via a transmission control protocol/internet protocol (TCP/IP) to a first data network; one or more host workstations communicating via TCP/IP to the first data network; one or more subscriber customer premise equipment (CPE) stations coupled with the wireless base station over a shared bandwidth via TCP/IP over a wireless medium; and one or more subscriber workstations coupled via TCP/IP to each of the subscriber CPE stations over a second network. The system can allocate shared bandwidth among the subscriber CPE stations to optimize end-user quality of service (QoS). The first data network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN). The second network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN).

An application aware, quality of service (QoS) sensitive, media access control (MAC) layer includes an application-aware resource allocator, where the resource allocator allocates bandwidth resource to an application based on an application type. The application type can be based on input from at least one of: a packet header; and an application communication to the MAC layer. The application communication includes: a communication between the application, running on at least one of a subscriber workstation and a host workstation, and the MAC layer, running on at least one of a subscriber CPE station and a wireless base station. The bandwidth resource is wireless bandwidth. The resource allocator schedules bandwidth resource to an IP flow. The IP flow includes at least one of: a transmission control protocol/internet protocol (TCP/IP) IP flow; and a user datagram protocol/internet protocol (UDP/IP) IP flow. The resource allocator in scheduling takes into account resource requirements of at least one of a source application and a destination application of an IP flow. The resource allocator takes into account IP flow identification information extracted from at least one packet header field. The bandwidth resource is wireless bandwidth. The resource allocator allocates switching resource to an application based on an application type. The application type is based on input from at least one of: packet header; and an application communication to the MAC layer. The application communication includes a communication between an application, running on at least one of a subscriber workstation and a host workstation, and the MAC layer, running on at least one of a subscriber CPE station and a wireless base station. The application communication includes a priority class of the IP flow.

A portable data collection device including an imaging assembly including a two dimensional (2D) photosensor array. The imaging assembly is selectively actuatable with a first trigger for reading a target dataform in the imaging assembly's target area and actuatable with a second trigger for capturing a image of the target object in the target area. The device also includes an illumination assembly including an circuit board assembly supporting illumination and targeting light emitting diodes and a lens array or panel positioned adjacent the circuit board assembly for focusing an even pattern of illumination on the target area and generating a crosshair illumination pattern for aiming the device at the target dataform. The device further includes an optic assembly for focusing reflected illumination from the target area onto the two dimensional photosensor array. The optic assembly includes a focusing optic for changing a best focus distance of the optic assembly as a function of moving a wedge shaped optic with respect to a stationary optic to change a thickness of the focusing optic.

The device includes an imaging assembly including a two dimensional (2D) photosensor array overlied by a RGB color filter. The imaging assembly includes an illumination assembly providing a relatively uniform illumination pattern over an imaging target area. The illumination assembly includes a plurality of sets of surface mount illumination LEDs mounted on a board and a spaced apart lens array for focusing the LEDs on the target area. The lens array includes orthogonal cylindrical optical entry and exit surfaces aligned with each of the illumination LED sets. The optical entry surface defines illumination intensity distribution horizontally while the optical exit surface defines illumination intensity distribution vertically. The board also supports a pair of spaced apart targeting LEDs. The lens array includes aspherical optical entry surfaces and cylindrical optical exit surfaces aligned with each of the targeting LEDs. The cylindrical optical exit surfaces are tipped with respect to their corresponding aspherical optical entry surfaces and are orthognal to each other providing an orgthogonal or "crosshairs" illumination pattern for aiming the imaging assembly at a target.

A system for extracting handwritten or typed information from forms that have been printed in colors other than the color of the handwritten or typed information. The information extraction system includes a detector for detecting color values for scanned pixel locations on a printed form; a comparator for comparing the color values with reference color values; an identifier for identifying ones of the scanned pixel locations that have color values that correspond to the reference color values; and an optical character recognition engine for receiving data regarding the identified locations.

A desktop printing system for use with microprocessor-based computers includes the modular combination of a color printer and a monochrome text printer. Preferably, the color printer is of the type which prints color graphics incrementally and the text printer is of the type which prints monochrome text continuously. In operation, printing information is segregated into color and text components, and the color printer is controlled to print only color components while the text printer is controlled to print only monochrome text components.

A method and apparatus controls network bandwidth between a first node and a second node on a network. A data element transmitted from the first node to the second node is intercepted. The data element comprises a data portion and a header portion including an original window size. The original window size in the header portion of the data element is replaced with a replacement window size, the data portion of the data element remaining unmodified. The data element is then routed to the second node, the header portion of the data element being coupled to the replacement window size.
