    Abstract: The present invention is a system for maintaining processing continuity between a mobile processing unit (26) and remotely resident applications (68). The system includes a network backbone (12), at least one stationary processor coupled to the backbone (12), and at least one transceiver (16) coupled to the backbone. The transceivers (16) are configured to communicate with the mobile unit (26) through a wireless medium. Mobile units intermittently communicate with applications The present invention employs a process that is dedicated to handling all communications between its associated mobile unit and applications. This process is responsible for the scheduling of communications sessions with the mobile unit.

    Abstract: A system to quickly locate and identify objects (OBJ.1,OBJ.2,OBJ.N) at a distance in a room (10-12) at work or at home. A base station (14-16) in each room (10-12) obtains the location of objects in that room, which is communicated to other base stations (14-16) so that the information can be interrogated by a user for any of the objects (OBJ.1,OBJ.2,OBJ.N) in any of the rooms/locations. The system uses miniature electronic identification devices in the form of small, optically coded "tags" (29-31;Fig. 2) that combine active electronics and an IR detection method based on a small, low-cost, liquidcrystal display "shutter" built into each tag. To obtain the location of the objects (OBJ.1,OBJ.2,OBJ.N), the base system (14-16) in each room illuminates the room (10-12) with pulses of infrared light and receives identification code sequences reflected by the various objects as they rapidly activate their shutters during the pulse. To avoid all the tags flashing at once, causing individual responses to "collide," the various tags (29-31;Fig. 2) are programmed to respond at random intervals so that the base station (14-16) can locate the objects by processing several pulses.

    Abstract: The present invention comprises a method and a system by which mobile, remote, adaptable controllers can dynamically control a multitude of resources within a given region (e.g. a room) such that policies determined for the region, controllers, and resources can be arbitrated in a manner that creates a meaningful work environment for users in the region. Furthermore, the present invention allows a controller to dynamically choose one of various modes of operation, either singly or in combination, allowing the user of the controller a maximum of flexibility in interacting with the resources in the region. These modes of operation comprise, but are not limited, to: a manual mode whereby a user may select a list of available resources that meet region-level policy and two automatic modes whereby controllers and resources may, without direct user input, make requests and allocation based on region-level policy and other constraints. The present invention maximizes the control of the resources of a region such that the control of the most suitable resources is dynamically situated in the hands of the user on an adaptable mobile controller.

    Abstract: A zoomorphic computer for controlling a computer system includes an animal or humanoid shaped shell (10) having an attached transceiver (32) for two way communication with a computer system. A position detecting unit (22) determines position of the zoomorphic shell relative to the computer system, with change of position of the zoomorphic shell relative to the computer system changing state the zoomorphic shell or the computer system. The zoomorphic shell (10) can have movable elements such as arms or tails, attached to the zoomorphic shell, and support a feedback unit that communicates with the computer system, modifying position of a movable element in response to computer system output.
