A system for locating an object that produces identifying signals comprises a plurality of receiver sites arranged in an array for receiving signals from the object and for receiving a common time reference in the form signals received from a global navigation system. The array comprises a reference receiver site and three auxiliary receiver sites that are connected to the reference site by data links. Each receiver site receives signals from the object and timing control signals from a global n...

The present invention provides an object catcher including a support shaft having a proximal end and a distal end, and a sheet portion arranged adjacent to the distal end of the support shaft. The sheet portion defines a periphery. The object catcher further includes a line having a first end portion and a second end portion and an intermediate portion between the first and second end portions. The intermediate portion of the line is slidably coupled to the periphery of the sheet portion, and th...

A three-dimensional modeling system. The modeling system includes an antenna and a stylus. The stylus has at least one tag that communicates with the antenna to provide position signals of the tag, allowing the stylus to trace the surface of an object into a processor. The system may include more than one antenna, each producing an electromagnetic field within which the object to be modeled is positioned. The stylus may have two tags, which will allow derivation of orientation information from t...

The invention relates to a coated object in which coatings remain of a constant and unchanged high quality despite operating temperatures of more than 350.degree. C. This is achieved with interlayers which deliberately interrupt and thereby stabilize the morphology of the coating.

There is disclosed an object locator system for obtaining information about the location of an individual, animal or moveable object, having a lightweight, attached object locator, that is present in a region served by a two-way paging system and a global positioning satellite system. The object locator may be selectively activated to conserve power or enabled to respond only when beyond a boundary.

An object sensing system (50), and method, employing electric field sensing, also known as quasi-electrostatic sensing and which may be termed cross capacitive sensing, is described. The system (50) includes at least one electrode arrangement (30), each electrode arrangement (30) includes one electric field sensing reception electrode (32) and two electric field sensing transmission electrodes (34, 36). One of the electric field sensing transmission electrodes (36) is driven with an alternating ...

A computer-implemented method for object localization includes providing a plurality of tags having fixed positions within an environment and known identifications, and providing a reader, for detecting the tags and reading the identifications, wherein the reader detects a plurality of tags within a scanning volume having a known shape. The method further includes determining positions for the plurality of tags within the scanning volume, and determining a position of the reader according to the...

An object detector including a detector, a setting device, a comparator and a display. The detector outputs a detected quantity based on a presence or absence of an object to be detected. The setting device sets a threshold, The comparator compares the detected quantity obtained by the detector with the threshold set by the setting device and outputs a detected result. The display numerically displays either the detected quantity obtained by the detector or the threshold set by the setting devic...
