Abstract: The present invention teaches a variety of methods and systems for providing computer/human interfaces. According to one method, the user interfaces with an electronic device such as a computer system by engaging a sensor with desired regions of an encoded physical medium. The encoded physical medium is preferably chosen to provide intuitive meaning to the user, and is thus an improved metaphor for interfacing with the computer system. Suitable examples of the encoded physical medium include a data-linked book magazine, globe, or article of clothing. Some or all of the selected regions have had certain information encoded therein, information suitable for interfacing and controlling the computer system. When the user engages the sensor with a region having a certain encoded information, the certain encoded information is interpreted and an appropriate action taken. For example, the sensor or the computer system may provide suitable feedback to the user.

Abstract: An XML processing system for use in a barcode printer apparatus includes a computer system operatively coupled to the barcode printer apparatus. The computer system further includes an XML processor configured to receive, parse, and process an XML input data stream and obtain schema identified in the XML data stream from a schema repository. The XML processor validates the XML data stream based upon the schema obtained. Also included is an XSLT processor configured to obtain a stylesheet identified in the XML data stream from a stylesheet repository. The XSLT processor transforms data in the XML input data stream into transformed XML data based upon the stylesheet obtained. Also, an XSLFO processor formats the transformed XML data into formatted XML data based upon XSLFO instructions contained in the stylesheet. A barcode rendering subsystem then receives the formatted XML data and generates a bit map representative of the bar code label.

Abstract: A system and method that facilitates the recovery of bar code scanning errors due to irregularities in the bar code. When a bar code scanning error occurs, the system displays the erroneously scanned bar code indicating the characters that could not be resolved successfully. The store clerk or operator need only fill the missing digit to confirm the scanned item without manually entering the entire code. Alternatively, a search engine evaluates the portions of the bar code which have been successfully resolved and displays a text and/or graphics list of all products having the resolved portion of the bar code. The store clerk or operator then need only choose the correct item from the screen list to confirm the sale. A printer allows the completed bar code to be printed on a receipt paper. The user of the system may then use the printed bar code for items that continuously result in a bar code error. The system may further keep a list of erroneously scanned bar codes.

Abstract: A bar code scanner is equipped with a keyboard emulation mechanism so as to provide an enhanced interface to a keyboard controller port of a computing device such as a personal or laptop computer. The keyboard emulation mechanism eliminates the necessity of connecting an actual computer keyboard to the port by responding to the computing device's standard power-on diagnostic procedure as if it were effectively an electrical equivalent of a computer keyboard. The keyboard emulation mechanism can also be equipped to detect a keyboard inhibit signal at the keyboard controller port. If the keyboard emulation mechanism detects a keyboard inhibit signal while a data byte is being transmitted to the keyboard controller port, the keyboard emulation mechanism retransmits this data byte to the keyboard controller port. The data byte may specify a scan code corresponding to a keyboard key press or all or part of a decoded bar code.

Abstract: A scanning projection light source for a barcode device includes a laser diode, a converging lens located in front of the laser diode, a first photo mask located in front of the converging lens having a round aperture formed therein, and a second photo mask located in front of the first photo mask having a second aperture formed therein. The second aperture has two arched light blocking tabs located at two lateral sides for partly covering the round aperture. The laser diode emits a light spot to the converging lens which transforms the light spot to a parallel light beam. The parallel light beam is projected to the first photo mask through the round aperture to become a round light spot which passes through the second aperture and become an output light spot having arched tangent sides. The arched tangent sides are approximate to straight lines at a close distance and will result in a high resolution, and become arched tangent sides at a longer distance for scanning a lower resolution barcode.

Abstract: Disclosed is a method and apparatus for controlling multistage systems where the relative capacities (process gains) of each stage are known. The method uses a split-range control concept in order to control multiple stages with a single feedback controller, such as PID. Stage combinations are generated automatically and sequenced to provide contiguous control and optimum control resolution across the overall range of the multistage system. The control method incorporates hysteretic deadzones to improve robustness around stage transition points. The assumption of a tuned PI feedback controller allows the size of the deadzone to be related to general control performance requirements applicable across classes of similar systems. A simulated HVAC&R system is used to evaluate the method and it is compared an alternative approach.

Abstract: A fin disengagement device for limiting the range of a projectile uses an electronic safe and arm circuit to sense launch and spin levels. Once armed, the stored energy from the electronic safe and arm circuit is dumped into an initiator or directly to explosive bolts.
