International Classification:

G06K 900

US Classification:

382187, 382189, 382314, 345169

Abstract:

A user interface allows a user to input handwritten, key-press, and spoken text in a seamless, synchronized manner. A text input panel accepts soft keyboard presses and handwritten words, characters, and gestures. A text recognizer/synchronizer integrates textual input from various sources while recognizing and preserving the order in which a user entered text via the soft keyboard, via handwriting, and/or by speaking. Synchronized text may be displayed in a stage area of the text input panel before being passed to an operating system message router and/or an application program. While in handwriting recognition mode, various permutations and combinations of a word recognition area, a character recognition area, and a keybar/keypad may optionally be displayed.

International Classification:

G09G005/00

US Classification:

345179, 345173, 345156, 345863

Abstract:

A technique is disclosed for detecting an in-air gesture made by a digitizing pen above a digitizing writing surface. When the digitizing pen is determined to be in motion above the digitizing writing surface, positional information of the digitizing pen with respect to the surface of the digitizing writing surface is recorded within a moving buffer. The moving buffer records a predetermined amount of positional information spanning a predetermined amount of time while the digitizing pen is in motion above the digitizing writing surface. When the digitizing pen has stopped motion, positional information recorded in the moving buffer is evaluated for determining whether the recorded information corresponds to a predetermined in-air gesture. A predetermined user interface panel is displayed when the positional information recorded in the moving buffer corresponds to a predetermined in-air gesture.

US Classification:

345163, 345173, 715773

Abstract:

A system and method for emulating the functional behavior of a two-button mouse-type computer input device is described. A predetermined input generated by digitizing pen and a digitizing writing surface is received, and a user interface having a plurality of soft buttons is displayed. The plurality of soft buttons provides selectable functionality of a two-button mouse-type computer input device. Preferably, the plurality of soft buttons includes a right-button function, a shift function, a control function, an alternate function and a bull's-eye function.

Assignee:

Xirrus, Inc. - Thousand Oaks CA

International Classification:

H04W 24/00

US Classification:

4554561

Abstract:

A system for quantifying the shadow fading observed in a wireless environment having multiple wireless access points is also provided. A distance determination module is in signal communication with the wireless access points. The distance determination module determines a distance between a pair of the wireless access points based on location information that relates to the locations of the wireless access points at the wireless environment. A shadow fading determination module is also in signal communication with the wireless access points. The shadow fading determination module determines a shadow fading factor based on the distance between a pair of the wireless access points and based on RSS information received from one of the wireless access points in the pair of wireless access points.

Appl. No.:

6/033453

Inventors:

James K. Mathews - Van Nuys CA

Assignee:

Pertron Controls Corporation - Canoga Park CA

International Classification:

H02H 7127

US Classification:

323320

Abstract:

An interface circuit is provided for interconnecting an electronic controller to a contactor circuit which, in turn, controls the alternating current flow from an alternating current power source to controlled equipment, such as a resistance welding machine. The contactor circuit, for example, includes a pair of semiconductor switching devices, such as silicon controlled rectifiers (SCR)s, the two semiconductor switching devices are alternately rendered conductive during successive half-cycles of the alternating current power from the alternating current power source at times controlled by the controller for the controlled operation of the welding machine. The interface circuit includes means for monitoring the junction temperature of each of the semiconductor switching devices, and to provide an indication and a control effect should the junction temperature exceed a particular safe threshold.

Inventors:

James K. Mathews - Van Nuys CA

Assignee:

Pertron Controls Corporation - Canoga Park CA

International Classification:

B23K 1124

US Classification:

219110

Abstract:

A control system for use with a welding machine controller is provided which senses the dynamic resistance of the weld being formed by the welding machine, and which generates appropriate signals indicating the condition of the weld, which signals may be used for automatically controlling the operation of the controller. The control system of the invention senses the power factor in the primary circuit of the welding transformer included in the welding machine which is a measure of the dynamic resistance of the weld being formed, and the control system produces signals indicating the dynamic resistance of the weld, which signals may be digitized to produce appropriate control signals for the controller.

Inventors:

James K. Mathews - Van Nuys CA

Assignee:

Pertron Controls Corporation - Van Nuys CA

International Classification:

B23K 1124

US Classification:

219114

Abstract:

A precision resistance welding machine controller is provided which may be set to deliver welding power to each of a multiplicity of welding operations on a precisely controlled repeatable basis. The controller of the invention is modular in nature and is microprocessor controlled. The controller includes a master control module which is standard for all models, and the master control module incorporates certain control circuits including a circuit for assuring that an accurately controlled amount of power is delivered for each welding operation. This is achieved by providing precise phase angle control despite variations in line voltage, and line noise disturbances. The controller also includes a personality module which is constructed for a particular welding operation, and which is programmed to incorporate any selected number of steps to be performed in sequence by the welding machine controlled thereby in carrying out the particular welding operation. The duration of each step of the welding machine, and the amount of welding power to be delivered, is set for the particular welding operation by adjustable controls on the personality module. The master control module of the controller of the invention also includes circuitry and controls for providing a self-test capabiliity for the controller.
