Abstract: The wireless power transmission is a system for providing wireless charging and/or primary power to electronic/electrical devices via microwave energy. The microwave energy is focused to a location by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power.

Abstract: A barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code access codes. The barrier movement operator provides a method and apparatus for learning valid security codes by a security code receiver comprising receiving a first previously learned security code and beginning a learn mode operation in response thereto, within a predetermined period of time, receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code.

Abstract: A radio frequency identification tag system (10) utilizes a radio frequency identification tag (16) that includes a display (40). The display has an electrooptic display (458) sandwiched between a first display electrode 454 and an optically transparent second display electrode (456). The electrooptic display is preferably formed by the print deposition of a microencapsulated electrophoretic material between the first display electrode and the second display electrode.

Abstract: A security device and a method for controlling operating status of portable computers with a pager to prevent unauthorized access to information stored in the portable computers, in the event of a theft or a loss are disclosed. The security device for a portable computer comprises: a memory for storing pager processing routine; data processing means for receiving, storing, and determining paged information to generate a corresponding interrupt signal according to a determined result; and a controller for displaying a message or a telephone number, or for changing system password by performing the pager processing routine, according the interrupt signal from the data processing means.

Abstract: A wide area paging broadcast channel for transmitting a page signal throughout a prescribed geographic area over a broadcast channel in response to a page request. At least one subscriber transceiver is located within the prescribe geographic area for receiving the page. In response to the received page signal, the subscriber transceiver transmits information back to the paging control center. However, the backhaul to the paging control center is accomplished by a plurality of base stations. Each base station forms a node in a mesh network of base stations which covers the prescribed geographic area. The subscriber transceiver may transmit information packets to nodes within the mesh network using a multiple access scheme with or without carrier sense access. The mesh network automatically selects which neighboring node to use for forwarding packets. Finally, a gateway device links the mesh network of base stations to the control center.

Abstract: This invention is for encoding of Chinese & Japanese ideographic characters which are digitized into a numeric format compatible for computer access and retrieval. Each Chinese & Japanese character is indexed by a numerical code. Each character is individually identified by an eight(8)-digit Geo-Stroke code, comprised of a four (4)-digit "FRAME" code and a four (4)-digit "ID" code. The coding method conforms to general writing habits, resulting in an input method both easy and convenient for an operator to learn and utilize. Each of the (10) Geostrokes used to input Chinese & Japanese character is assigned to a numeric digit (0-9). Each of the Geostrokes resembles one of the numeric digits available on the 10-key pad. By using this method both Chinese and Japanese ideographic character can be easily input and retrieved by using a 10-key design.
