摘要： An automatic exposure system for an imaging-based bar code reader. The automatic identification system includes: an aiming apparatus generating a beam to aid in aiming the system at a target object when the system is actuated; an imaging system including a pixel array, a focusing lens to focus an image of the target object onto the pixel array; and an automatic exposure system to determine an integration time for capturing an image of the target object. The automatic exposure system determines an integration time by: projecting an aiming pattern on the target object and capturing an image of the aiming pattern; determining a target distance from the imaging system to the target object based on a location of the aiming pattern within the captured image; determining a gain-integration time product utilizing an equation wherein the gain-integration time product is a function of a predetermined target image brightness and the target distance; and determining the integration time by selecting a gain value and solving for integration time given the gain-integration time product.

摘要： A method and apparatus for implementing alerts on a browser running on a portable handheld device is disclosed. The method generates an asynchronous notification action from the server and in response transmits an alert containing a message indicating availability of HTML pages that describe the nature of the alert. The alert is received at a node on a network and translated into the original message. An alert receipt acknowledgment is transmitted to the server. Access to the alert HTML page is provided through a URL containing the appropriate query strings necessary to present the appropriate HTML page. The invention also discloses a wireless local area network (WLAN) adapter associated with a wireless network that receives paging signals from a server on the network and returns an acknowledgment signal back to the server. The invention also discloses a client/server based method of delivering messages initiated by a client. After a connection is established between a client and server, the client requests a message from the server. In response, the server retrieves and returns the message back to the client.

摘要： A method and imaging assembly (10) are disclosed adapted for reading a target object comprising a scan engine (48) having a sensor (46), focusing optics (44), and an imager (48). The scan engine includes a field-of-view defining an area to be imaged by the imaging assembly (10). A housing (80) internally lodges the scan engine (48) and an illumination source (36). The illumination source (36) is adapted to project illumination from the housing (80). A boot (30) extends from the housing (80) for shaping the illumination as it passes through the boot to form an illumination pattern from the illumination. The illumination pattern substantially conforms to a geometrical shape of the boot (30) and is adapted to envelope the scan engine field-of-view.

摘要： Document information is encoded in a graphic symbol applied to the document. The symbol is read to retrieve the document information which is then translated into a humanly discernible form different from that appearing on the document. In one embodiment of the invention, a symbol is applied to sheet music and encoded with the music score printed thereon. The symbol can then be read to produce an audio rendition of the music score. Also, a symbol can be applied to a printed text page and text encoded. The symbol can then be read to produce a vocal reading of the text. Other applications using encoded symbols to uniquely identify or memorialize persons named on credit cards and business cards are disclosed.

摘要： A scanner has a window in its housing through which the scanning beam emerges to impinge upon an indicia to be read. The beam scans in a raster fashion over the window, and as it does so it impinges upon beam position indicating means which locate the position of the beam with respect to the scanner in at least certain portions of the scan pattern. Specifically, the beam position indicating means determines the position of the beam in a direction perpendicular to the overall scanning direction. In a preferred embodiment, the beam position indicating means may comprise one or more CCD's which provide electrical output signals dependent upon the position of the beam when it impinges upon them. Alternatively, the beam position indicating means may comprise passive code means such as a stacked series of bar code symbols. The location of the beam when it scans across the symbol can be determined by the unique pattern of reflections.

摘要： Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by uniformly illuminating the markings. An illuminator is operative for emitting illumination light of greater and lesser intensity toward the indicia. A diffuser is operative for diffusing the illumination light en route to the indicia. The diffuser includes a plurality of diffusing elements adjacent the illuminator for diffusing the illumination light of greater intensity more than the illumination light of lesser intensity.
