  • Patent number: 6642632
    Abstract: The present invention is a battery transfer circuit connected to a load, a power supply for powering the load with at least a minimum supply voltage during normal operating conditions, and a source of battery voltage for powering the load during a power fail condition when the power supply is unable to power said load at the minimum supply voltage. The battery transfer circuit comprises a first circuit for applying at least the minimum supply voltage to the load during normal operating conditions and a second circuit for charging the battery to an optimal voltage greater than the minimum supply voltage and for down-regulating the optimal charge voltage to a predetermined voltage and for applying the predetermined voltage to the load during the power fail condition, wherein the predetermined voltage is less than the minimum supply voltage.

  • Patent number: 6641309
    Abstract: Many device components include a printed circuit board supporting light-generating means along with a light pipe to conduct light from the light-generating means to a diffuser adjacent the surface of the components. The present invention offers an improvement whereby the light pipe can be utilized both for transmission of visible wavelengths and for transmission/reception of invisible (infrared) wavelengths. To accomplish this, a light pipe is constituted of two adjacent portions, and an infrared transceiver module is coupled into both portions.

  • Patent number: 6625499
    Abstract: A method of manipulation of cells within a table on an interactive user display comprising the steps of: (a) selecting a subset of cells of the table as a block on the display, the block having an orientation of fields of the cells along at least one dimension; (b) determining data characteristics of the block for each the field in the direction of the orientation; (c) selecting representative data from the block for each the field in the direction of the orientation; (d) generating a first interface displaying for each the field (i) one or more of the data characteristics; and (ii) corresponding the representative data as an editable element; (e) making user desired modifications to each the editable element to form a changed elements; (f) applying corresponding modifications of each the changed element to all cells of the block in a direction perpendicular to the orientation to form an altered block; and (g) outputting the altered block to the table for display.

  • Publication number: 20030158722
    Abstract: A voice activated language translation system that is accessed by telephones where voice messages of a caller are translated into a selected language and returned to the caller or optionally sent to another caller. A voice recognition system converts the voice messages into text of a first language. The text is then translated into text of the selected language. The text of the selected language is then converted into voice.

  • Patent number: 6581315
    Abstract: A flat, substantially transparent lens lying in a flat plane retains a designation card within a recess in a surface. The lens is made of flexible sheet plastic with means at either end for securing the lens in the recess. At one end, a tab is integral with the lens and has an attachment end which joins the lens. The tab extends away from the plane of the lens to a geniculation spaced from the lens plane. At the geniculation, the tab reverses direction and extends toward the lens plane to return generally to that plane, where it terminates in a finger grip.

  • Publication number: 20030099340
    Abstract: A system is provided for automatic feature enablement on the basis of a user's current location, in order to enable the most appropriate set of features. The system is implemented within a tuple space for allowing communication among system components. A location service is provided for tracking the location of a user. Policy daemons are created which contain user specified policies to select appropriate feature sets depending on the user's location. An interface is provided for specifying user preferences for features depending on location. Finally, a basic PBX feature architecture is used which consists of a database to hold individual user feature selections as a set of tuples and a call processing system which uses these feature selections.
