Abstract: Described is an improved trigger assembly for use in an electronic device. The trigger assembly includes a pressure sensitive member and a trigger button. The pressure sensitive member includes two or more conductive lines. The pressure sensitive member is secured to a portion of the mobile terminal. The trigger button is secured to the mobile terminal in a manner such that a force applied to the trigger button causes a resultant force to be applied on the pressure sensitive member. The force applied on the pressure sensitive member causes a change in an electrical property between at least two of the conductive lines. A module measures the electrical property between the conductive lines. A function of the device is initiated depending on a comparison of the measured electrical property to a threshold value.

Abstract: A method for pipelined processing of access commands to a population of radio frequency identification (RFID) tags is provided. The method includes transmitting a first queued access command to a first tag in the population of RFID tags, transmitting a second queued access command to a second tag in the population of RFID tags, and transmitting a status request command to the first tag. The queued access command causes the first tag to perform an operation and upon completion of the operation, to suspend transaction processing. The second queued access command is transmitted while the first tag is performing the command operation. The status request command causes the first tag to resume normal processing.

Abstract: A bar code scanning system and method for reading and processing bar code symbology uses a scanning station installed above the check-out stand and a receiving station at some distance away from the scanning station. The scanning station projects light onto a surface of the check-out stand. The projected light can have a well defined border indicating where a user should place items to be scanned. Alternatively, a pattern coincident with the projected light can be projected onto the surface and which includes a target indicating where items should be placed for scanning. Light reflected by items in the target region is processed to decode optical symbology on the item and produce a signal that is representative of said sensed symbology. Information about the scanned item can be processed and displayed by the receiving station for use in, e.g., a point-of-sale transaction.

Abstract: An illumination apparatus for an imaging-based bar code reader including an illumination source directing illumination through a focusing lens to generate an illumination pattern directed toward a target object; and the focusing lens including a first optical surface facing the illumination source and a second optical surface facing the target object. The first optical surface, when viewed with respect to the lens horizontal axis, includes a central region having concave curvature and peripheral regions spaced on opposite sides of the central region having convex curvature such that the generated illumination pattern includes variation in illumination intensity projected toward the target object, namely, a central portion of the illumination pattern has relatively lower illumination intensity and outer peripheral portions of the illumination pattern on opposite sides of the central portion have relatively greater illumination intensity.

Abstract: A method and apparatus for illuminating a target object such as a bar code having areas of differing light reflectivity on the target. A bar code reader has a light source that is selectively activated and a reflecting mirror for reflecting light from the source from a housing to a target object within a field of view of an imaging capturing device. One suitable mirror is a parabolic mirror having a focal point approximately at the location of the light source.

Abstract: Methods and apparatuses for assembling and implementing tamper indicating RFID devices are presented. An RFID device includes a substrate, an electrically conductive pattern formed on the substrate configured to operate as an antenna by separating a portion of a first device section from a second device section, and an electrical circuit mounted on the substrate that is electrically coupled to the antenna. The electrical circuit stores an identification code.

Abstract: Embodiments include methods and systems by which an object can be located within an area. The system includes a moveable radio frequency identification (RFID) tag reader and multiple RFID tags, which are positioned at known locations. The RFID tag reader is associated with the object, and is adapted to interrogate the RFID tags, to receive unique identifiers from responding RFID tags, to correlate the unique identifiers with tag location information stored in memory to determine fixed positions for the responding RFID tags, and to mathematically determine at least one location solution for the RFID tag reader using the fixed positions. A responding RFID tag is adapted to respond to an interrogation signal from the RFID tag reader by transmitting a unique identifier.

Abstract: An illumination assembly for emitting light for imaging a target object comprises an illumination source that emits at least one light beam upon activation toward an illumination guide. The illumination guide has a first and a second side such that the light beam from the illumination source is scattered between the first and second sides. A textured surface is located substantially along the first side of the illumination guide. The scattered light exits the illumination guide from the textured surface to form a prescribed illumination pattern for imaging a target object.

Abstract: The present invention is directed to systems that use frequency selective surfaces (FSS) to aid in the operation of radio frequency identification (RFID) devices and products. In one embodiment, a system for interrogating radio frequency identification (RFID) tags includes a conveyor belt and an RFID reader. The conveyor belt has a first surface and a second surface. The first surface is configured to receive an item to which an RFID tag is affixed and the second surface is configured to slide on a metal slide plate. The RFID reader is configured to transmit instructions embodied in a radio frequency (RF) signal to the RFID tag, wherein the metal slide plate is positioned between the RFID reader and the RFID tag and comprises a frequency selective surface that is substantially transparent to the RF signal.

Abstract: A software-programmed controller supported by a mobile electro-optical reader is operative for sensing when the mobile reader is supported in a steady state by the operator for a predetermined time period, and for automatically actuating the mobile reader in response to sensing the steady state to initiate reading of indicia while the mobile reader is supported in the steady state by the operator for the predetermined time period.

Abstract: A transaction device adds or injects a random noise component into signals representing (x,y) coordinate signals associated with user interface with an input screen associated with the device. The noise component can be generated by converting to analog the output of a random number generator, and then adding the noise component to the x-axis and/or y-axis component of the (x,y) coordinate signal. Alternatively the noise component can be injected into the x-axis and/or y-axis operating potential for the input screen. The result is a masking of the original (x,y) positional information. The randomly generated number is only available internal to the device. The device can use this number to de-crypt the true (x,y) signals, which signals can then be re-encrypted before transmitting from the device.

Abstract: Methods and apparatuses for tracking an item having an associated radio frequency identification (RFID) tag are described. A change in a physical attribute of the item is detected. Information stored in the tag is updated based on the detected change. Information stored in a database may also be updated based on the detected change. In another aspect, a second tag associated with a person is determined to be located within a predetermined range of a first tag associated with an item. As a result, information is stored in the first tag regarding the person.
