Abstract: An improvement in manual bar code readers to improve the reliability and eliminate read errors. The improvement comprises a plurality of sensors in a single unit arranged such that a single manual scan results in multiple reads of the bar code. The results of the reads are then compared bit-wise and any read error in any bit is corrected via a bitwise majority voting scheme.

Abstract: Input devices for use with radiotelephones, and other electronic devices, recognize and display handwritten alphanumeric characters on a display. A plurality of adjacent touch switches are arranged in an array beneath an exposed touch pad. Each touch switch in the array produces, in response to user activation of an area of the touch pad during a handwriting stroke, a respective analog voltage signal. An analog/digital converter receives and converts a sequence of analog voltage signals produced by a user activating one or more of the touch switches during a handwriting stroke into a sequence of digital values. A processor, working in conjunction with a handwriting recognition algorithm, processes the sequence of digital values, recognizes the alphanumeric characters that corresponds to the handwriting strokes of the user, and then displays the recognized alphanumeric characters within the display.

Abstract: A multi-function keyboard in which at least some of the individual keys are actuable in a first mode in which a single character is displayed, and a second mode in which a first, a second or a third character is displayed. A switch permits selection of the desired mode which activates different key press click sounds depending on mode of operation..

Abstract: The invention discloses a method for improving the compatibility GPS receivers and cellular telephones, typically when both are found in the same unit. The invention solves the problem of the GPS receiver and the cellular telephone sharing the same antenna, and also discloses an embodiment wherein a second, diversity antenna is used for the GPS receiver. In both cases, switching circuitry is provided to switch disconnect the GPS receiver from the main antenna when the cellular telephone is transmitting.

Abstract: Antenna systems for electronic devices, such as radiotelephones, include a paging antenna that enhances paging mode operation when a pivotable primary antenna is in a stored position. Paging antennas are disposed within a hinge rotatably secured to one end of a radiotelephone housing. A primary antenna, in electrical communication with the transceiver, is secured to the hinge and rotatable therewith along a predetermined path of rotation from a stored position adjacent the housing to an operating position extending away from the housing. Radiation axes for a primary antenna and a paging antenna are orthogonal.

Abstract: A hands-free headset includes first and second earpieces and is configured such that the second earpiece is integrally mounted to and stowed against the first earpiece during mono-communications operation or during storage. The headset includes two retractable cords which engage with a portable communications device. A sliding grommet attached to the retractable cords controls the separation of the cords and facilitates the two cords being reeled into a common cord reel. The headset also includes a switch which directs the desired electrical path to either stereo listening or communications operation. The headset further includes a docking platform which can be attached to the body of the portable communications device for storage and which holds the integral mounted earpieces against the cord storage reel for an aesthetic stowed hands-free device.

A second input device is electrically coupled to the conductor, and the second input device applies one of a plurality of DC signals to the conductor in response to input thereto. A microphone signal can be coupled to the conductor, and automatically passed to or blocked from the conductor by DC level generated by the second input device. A DC detector circuit is coupled to the conductor, and the DC detector circuit determines the DC signal generated by the second input device. Related methods also are discussed.

The captured picture has a boundary about its object, and the position indicator is a frame for the captured picture corresponding to the boundary. The video display displays the captured picture frame in a position corresponding to the location of the object with the video display.

Abstract: A personal computing device comprises a chassis having a top and a bottom and a keyboard movably secured to the chassis. The keyboard includes a pair of laterally spaced arms with each arm having a connector that projects therefrom and confined within an elongated slot formed on the side of the chassis. This enables the keyboard to move between three different positions: (1) a closed position where the keyboard lies adjacent the top of the chassis, (2) an open position where the keyboard extends outwardly from the chassis, and (3) a stowed position where the keyboard lies adjacent the bottom of the chassis. Both the chassis and keyboard include IR ports that enable the keyboard to communicate with the chassis, thereby eliminating a wire connection between the chassis and keyboard.

Abstract: The initial portion of an audio work received from an audio source is temporarily buffered so as to allow a user to make a recording of an audio work, including the initial portion of the audio work, even when the decision to record is made after the audio work has begun. In one embodiment, the incoming data stream representing the audio work is monitored for the presence of a sound gap, indicating the beginning of a new audio work. A DSP compresses the data, preferably according to perceptual coding technique such as MPEG-3 or Windows Media Technology 4.0, and forwards the compressed data to a short term memory buffer, such as a simple FIFO buffer, for temporary storage. If the user initiates a recording procedure before buffer is filled, a central controller pulls the compressed data from the buffer and transfers it to long term memory. If the user fails to act before the buffer fills, the buffer is flushed, and the process prepares for the next audio work.

Abstract: Retractable antennas with quarter wave-quarter wave resonances for telephones, and which are particularly suitable for radiotelephones, include a retractable antenna with a top load element, a spatially separated rod element, and a cylindrical support conductor positioned therebetween. The cylindrical support conductor is structurally configured to receive a portion of the rod therein to add structural rigidity to the antenna and to define a coaxial capacitor between the rod and the conductor when the antenna is in the extended position.
