Filed:

Sep 1, 1999

Appl. No.:

09/388092

Inventors:

Seung Kil Kim - Chapel Hill NC

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H05K 716

US Classification:

361683, 361680, 361686, 400489, 3122084, 345168

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.

Seung Kil Kim - Chapel Hill NC

Assignee:

Ericsson, Inc. - Research Triangle Park NC

International Classification:

H04N 714

US Classification:

348 1401, 348 1407, 348 1416

Abstract:

A communication including a camera adapted to capture a picture, a transceiver adapted to receive a picture from a remote device and to transmit the picture captured by the camera, a processor adapted to recognize an object in the local picture and generate a position indicator of the object, and a video display adapted to display both the received remote picture and the position indicator, the position indicator being displayed on the video display to indicate the location of the local picture object. 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.

Appl. No.:

09/425647

Inventors:

Seung Kil Kim - Chapel Hill NC

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04B 138

US Classification:

455556, 455575, 345173

Abstract:

A user terminal includes a first input device, such as a microphone, electrically coupled to a conductor, wherein the microphone applies an AC signal to the conductor in response to input thereto. 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.

International Classification:

H04M 102

US Classification:

455569, 455575, 381309, 381374, 381375

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.

Inventors:

Seung Kil Kim - Chapel Hill NC

Assignee:

Ericsson, Inc. - Research Triangle Park NC

International Classification:

H04B 138

US Classification:

455550, 455129, 455272, 37943313

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.

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

G06K 928

US Classification:

382187, 328315, 178 1803, 455575

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:

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.
