摘要:
A bar code scanning system including an optical scanner for scanning a target symbol, such as a bar code, and generating a corresponding electrical signal. The scanner housing may be mounted to a single finger ring support, which can be cylindrical in shape. The scanner housing may include a scanner activation switch, which may be of the voice recognition type. A transmitter for transmitting the analog or digitized electrical signal, either by wire or RF signal, to a receiver on the user's person is also included in the scanner housing. A decoder is preferably included within the receiver housing. The receiver housing may also have a display for displaying decoded data and a keyboard for inputting entry data. Signal processing circuitry for digitizing the electrical signals generated by the scanner may be included either in the scanner or receiver housing. The receiver housing also may include an RF transmitter for transmitting the decoded data and any entry data to a separate computer unit. The receiver housing can be worn on the user's wrist or belt.

A symbol scanning system which adaptively changes scanning system parameters including light beam pattern and focus to improve barcode readability. The scanning system including; a scanner, responsive to coordinate control signals, for directing a light beam in a pattern at a symbol at a predetermined location, detecting a reflected portion of the light beam, and generating a feedback signal corresponding to the detected portion of the reflected light beam, a microprocessor, responsive to the feedback signal, for generating pattern control signals, and a pattern generator for generating the coordinate control signals in responsive to the pattern control signals and for determining the light beam pattern.

The laser diode of an optical scanning system is located in a separate unit and light therefrom carried to a remote scan head via an optical fiber. This reduces the size and weight as well as temperature sensitivity of the scan head. The separate unit may include an optical sensor for detecting light reflected from scanned symbols. If the separate unit houses the sensor, the same fiber or an additional fiber will collect the reflected light and transmit that light back to the sensor. An electromagnetic system produces a scanning motion of the beam emitted by the scan head where the optical fiber is attached to a magnet.

To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. A flexible support structure, such as one or more strips of mylar, movably mounts the objective lens in front of the light emitter. The objective lens is laterally reciprocated in response to a motive force, for example as might be applied by a combination of a permanent magnet coupled to the objective lens and a fixedly mounted electromagnet driven by an alternating current signal. Reciprocation of the objective lens during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label.

The system employs the use of biometric authentication, a fraud control gateway and widget, and a point of sale sensor to restrict the use of credit cards or other financial tokens to authenticated actual owners of the card or token. The card or token holder will have biometric information entered into a database during an initiation or enrollment process, and subsequent uses of the card may be authenticated by comparing the biometric information of the attempted user to biometric information stored in the system. The biometric component is used for voice authentication. As part of a multi-factor security schema, the biometric authentication is combined with a series of point of sale and fraud control methods to ensure a comprehensive security umbrella for financial transactions. Both financial institution limits to transactions and consumer-preferred limits to transactions are employed.
摘要:
A communications portal for interfacing with a carrier network, a contact center, and a user is disclosed. Telecommunications links are connected to the communications portal to receive inbound calls and place outbound calls. A gateway signaling proxy containing an application server and a reverse automation subsystem is connected to the telecommunications links to recognize and store user selections, detect answer supervision, and execute scripts as configured in the user interface.

Disclosed are compositions and methods for detecting oral and gastrointestinal cancers in a subject. Autoantigen p90 was shown to be overexpressed in oral cancer cells, and this protein, as well as its companion autoantigen p62 and antibodies directed to both proteins, can be used as markers for detecting oral digestive and other cancers in a subject at an early stage.
摘要:
A computing arrangement for determining a location of a wireless communications device includes a memory arrangement, a communication arrangement and a processor. The memory arrangement stores a location of each of at least three access points. The communication arrangement receives first data which includes at least one of first signal strength data and second signal strength data. The first signal strength data is indicative of a strength of a first signal transmitted by the device and received by the at least three access points. The second signal strength data is indicative of a strength of a second signal transmitted by the at least three access points and received by the device. The processor determines a location area of the device as a function of the first data and the location of each of the at least three access points, the location area being within a predetermined reception range of the at least three access points. The processor determines the location of the device within the location area as a function of second data. The second data is indicative of a travel time of a third signal from the device to each of the at least three access points.

A portable instrument incorporates an electro-optical assembly for reading indicia during for projecting a bit-mapped image during a display mode. A manually operable switch on the instrument is disposed for selecting one of the modes. The image is formed by pulsing a laser at selected times on selected scan lines.
