Abstract: A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having a piezoelectric material layer that may generate a voltage when deformed in a localized area. The piezoelectric layer may also include a pattern of sensors for detecting the voltage generated. The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen.

Abstract: A radio-frequency identification (RFID) system includes an RFID tag, an RFID reader, and a controller. The RFID reader employs a plurality of phase-offset or phase-diverse channels to improve detection of data transmitted from the RFID tag to the RFID reader. A controller selects the channel that provides the best signal-to-noise ratio and decodes the data provided by the RFID tag using the selected channel.

Abstract: This invention provides an extensible method for performing management operations on known and unknown targets. The extensible method is implemented on a fully extensible system where management software and triggers that cause these management operations to be run are easily extended in the field. The triggers may include information indicating a change in inventory, product state, or an event, and may originate directly from a product or from an information store containing information about installed products. The management software facilitates mining this information, parsing the information through a manifest of the triggers, and selecting functions to determine if a management operation should be executed, and if so, which management operation. Generally, the management software executes the selected management operation.

Abstract: A keypad overlay membrane provides guidance to a user in selecting an intended key to strike and avoiding striking unintended keys. In one arrangement the overlay membrane is formed by a continuous thin-walled sheet having an outwardly-facing surface and an opposed inwardly-facing surface. Formed into the thin-walled sheet are a first array of raised members and a second array of channels. The raised member array is laid out in a configuration for positioning atop individual keys of the electronic device keypad, with the channel array located between the raised member array. Upon placing the overlay membrane onto keypad, the user can apply a sufficient inwardly directed force to one of the raised members to induce movement of the respective key underlying and aligned with the particular raised member. In another arrangement, an array of concave depressions substitutes for the raised member array and channel array.

The computing device acquires environment identification data and performs at least one of a configuration command and a power state command on the input/output device based on the acquired environment identification data.

Abstract: A communication network having at least one access point supports wireless communication among a plurality of wireless roaming devices via a first and a second wireless channel. The access point comprises a first and a second transceiver. The first and second transceivers operate on the first and second wireless channels, respectively. Each of the plurality of wireless roaming devices are capable of communicating on the first and second wireless channel. In one embodiment, the first wireless channel is used to exchange data, while the second channel is used to manage such exchanges as well as access to the first channel. In an alternate embodiment, both channels are used to support communication flow, however the first channel supports a protocol that is more deterministic than that of the second channel. Allocation of ones of the plurality of wireless roaming devices from one channel to the next may occur per direction from the access point.

Abstract: A printer capable of operation with linered and/or liner-less media. Powder coated media surfaces, a silicone platen roller and tear-off blade are either designed into the media path or retrofitted into a linered media capable printer. To remove the requirement for realignment between the media path extrusion and the print head a media path extrusion cover designed to snap on to the media path extrusion is utilized.

Abstract: A scanning device has a field-replaceable antenna provided in a door/antenna module. The housing of the device has an outer shell defining an interior space and an access opening extending through the shell and communicating with the space. The door is removably secured to an outer surface of the shell and covers the access opening. An antenna is carried by the door and has a cable extending therefrom into the space. The cable has an outer end with a connector configured to engage a component located in the space. The door is attached to the shell by means of a pair of screw fasteners. The antenna may be externally and pivotally mounted on the door or mounted internally in the door. Preferably, the door has a gasket that seals against an outer surface of the shell to seal the access opening.

Abstract: An ejector is operable to move an ejector member against a data card in engagement with a connector to move the card along a pathway into an ejected position out of engagement with the connector. A latch member is mounted on the connector and has a blocking portion with a latch position in which it extends into the pathway to block movement of the card. The ejector includes a slide button that engages a lever to pivot the lever so that one end of the lever pushes on the card to push the card toward its ejected position. The positive latch action of the latch member prevents such movement unless the latch member is disengaged. The latch member preferably includes a leaf spring having a spring force that resists movement of its free outer end from a blocking position. A projection on the spring may be engaged to depress the spring into an unlatch position.

Abstract: A hand-held scanning device, such as a pistol-type bar code reader, has a housing having an outer shell defining an interior space. An outer opening in the shell communicates with the space. A tray has an inner portion and an outer closure portion with a sealing surface. The inner portion is sized and shaped to be introducible into and removable from the interior space through the opening. The outer closure portion is dimensioned to close the opening when the inner portion is in the space. The sealing surface sealingly engages an outer surface of the shell to protect the interior space and a component mounted on the inner portion from environmental contamination. The tray is easily removable from the device housing, and the component is easily demountable, to allow for quick and easy replacement of the component and/or tray. The closure portion may be provided with an access opening for a memory card to provide an interface between the component and other elements of the device carried by the housing.

Abstract: A vibration resistant mounting bracket has a base attachable to a support structure by bolts. Isolator bushings are positioned in the mounting holes in the bracket to isolate the bracket from shocks and vibration. A pair of arms project perpendicularly from the base. Each arm has a round opening and an arcuate opening concentric with the round opening. A first fastener pivotably connects a terminal to each arm of the bracket at a pivot axis defined by the round openings. A second fastener has a shaft extending through the arcuate opening and into a second threaded opening in the terminal. The second fastener may be tightened and loosened to secure the terminal in a pivot position relative to the bracket and release the terminal from the pivot position to change to a different pivot position.

Abstract: A data collection and dissemination system, in which one or more portable data terminals enter or disseminate data through a wireless access point to which they are communicatively coupled. The wireless access point is also coupled to a portable server for storing and retrieving the information requested by the portable data terminals. The portable server maintains a database for the purposes of storing data from and retrieving data for the portable data terminals. The portable data terminals initiate a transaction with the portable server via communication with the wireless access point. The portable data servers formulate a request to retrieve or store data using a database query. The database query is transmitted to the wireless access point, from which the query is directed to the portable server, which then stores or transmits the requested data.

Abstract: In an exemplary embodiment, a battery conditioning system monitors battery conditioning and includes a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle. With a microprocessor monitoring battery operation of a portable unit, a measure of remaining battery capacity can be calculated and displayed. Where the microprocessor and battery conditioning system memory are permanently secured to the battery so as to receive operating power therefrom during storage and handling, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters. In the case of a non-portable conditioning system, two-way communication may be established with a memory associated with the portable unit so that the portable unit can transmit to the conditioning system information concerning battery parameters (e.g.
