Abstract: An apparatus and a method of implementing a force feedback interface having isotonic and isometric control capability. The apparatus is coupled to a computer that displays a graphical environment. The interface includes a physical object (12) movable in physical space, such as a mouse. A sensor (51, 52) detects the object's movement, and an actuator (48) applies output force on the physical object. A mode selector (250a, 408) selects isotonic and isometric control modes of the interface from an input device or from an interaction between graphical objects. Isotonic mode provides input to the computer based on a position of the physical object and correspondingly updates a position of a cursor, and applies force sensations to the physical object. Isometric mode provides input to the computer based on an input force applied by the user to the physical object, where the input force is determined from a sensed deviation of the physical object. The input force opposes an output force applied by the actuator and is used to control a function of an application program, such as scrolling.

Title: Method and apparatus for determining remote unit location in a communication system
Inventor: SANDERS STEPHEN H III
IPC: H04W64/00
Filed: 1997-11-25
Granted: 2003-08-05
Abstract: The location of a remote unit (113) within a wireless communication system (100) is determined by all base stations (101) within the wireless communication system (100) initiating a first page (wide-area location page) that is broadcast to the remote unit (113) over a paging channel. The serving and neighbor base stations are determined from the remote unit's (113) response to the wide-area location page, and those base stations are instructed to tune receiving elements to obtain data that will be transmitted by the remote unit (113) during location. A second message (Location Page Message) is then broadcast to the remote unit (113) via the serving base station (101). The Location Page Message instructs the remote unit (113) to periodically transmit a known Remote Unit Location Message (RULM) with increasing power levels for a predetermined number of times so that the remote unit's (113) location can be achieved.

Abstract: Systems and methods for detecting changes, and in particular faults, in a changing environment (12) include constructing a profile is made of the environment using observations made during no fault condition (14). A range of values (14) for one or more "trusted"  variables (14) are identified as values indicative of a no fault condition. Data is also collected (only at times when the trusted variable(s) indicate(s) no fault) for other variables which may be indicative of a fault condition. Statistical profiles (19) are established for each of these other variables. The environment is continuously monitored and the normal profile, as well as the thresholds/ranges, are preferably continuously updated during normal conditions, as indicated by the trusted variable(s). When, during the monitoring of the environment, data for any of the fault detection variables, which may or may not include the trusted variable, exhibit values outside of the normal range, an alert is generated to indicate the possible presence of a fault. Depending on which of these variables exhibits an abnormal value, a diagnosis of the fault may be possible. A method for determining the accuracy of trusted and fault variables is also disclosed.

Title: Telecommunications network synchronization for data services

Granted: 2009-06-30
Abstract: A star network type topology is imple-mented or a network synchronization sys-tem wherein synchronization information ra-diates from a centralized primary reference source (46) comprising the global position-ing system (GPS). A GPS receiver (54) in-stalled at each mobile switching center (14) and base station (18) of a wireless commu-nications network supplies a stratum 1 clas-sified clock pulse to a local clock (40). The local clock trains to this clock pulse and gen-erates a corresponding stratum 1 classified synchronization clock pulse for controlling timing operations of the mobile switching center or base station. In the event the GPS primary reference source fails (72) or its ac-curacy degrades (74), a change is made to a tree or linear network type topology wherein the synchronization information flows down- stream from the mobile switching center lo-cal clocks to the base stations. Operation of the network synchronization system is co- -ordinated through a synchronization man-ager (52) maintained by the transport net-work management system (28) of the net-work. Highly accurate synchronization us-ing these topologies supports the provision of value added services such as mobile station locating (102) and information time stamp-ing.
