Abstract: Calibrating a receiver for a satellite positioning system. At preset intervals, a plurality of calibration signals are generated and applied to the receiver. The plurality of calibration signals correspond to a plurality of satellite signals, respectively, from the satellite positioning system. A relative time-delay bias from a delay estimation algorithm within the receiver. The time-delay bias is stored, preferably with the receiver. The receiver receives the plurality of satellite signals from the satellite positioning system. The plurality of satellite signals are processed with the time-delay bias. The processing reduces effects from the satellite receiver and improving estimate of the differential delay and total electron content (TEC).

The apparatus (1) comprises a tubular housing (2), first and second telescopic members (3, 4) extendible from and retractable into the housing (2), a drive (5, 60) for extending and retracting the telescopic members (3, 4), and a cable-engaging member (51) attached to the second telescopic member (4) for lifting one or more aerial cables (53). The drive (5, 60) comprises a chain lever block (5) and a pulley arrangement (60). In use, the apparatus (1) is positioned below one or more aerial cables (53), the chain lever block (5) is used to raise the first telescopic member (3), the first telescopic member (3) extends from within the housing (2), the second telescopic member (4) extends from within the first telescopic member (3), and cable-engaging member (51) raises the cable/s (53).

Abstract: The present invention relates to a parachute rescue system which is intended for rescuing people from danger zones and comprises a parachute and a seat. The seat can be maneuvered outwards into the open air from a multistory building by means of a guiding device through an opening in the walls of the building.

Abstract: A bit loading for a channel of a multi-carrier data communication system is generated. The bit loading has a target bit rate and satisfies predetermined performance criteria. When the channel is loaded according to the bit loading, a minimal number of sub-channels of the channel are active.

Abstract: A testing harness for a design-under-test is modified to include a standalone implementation of an application programming interface used in developing the design-under-test. The standalone implementation is adapted to a target device, and is packaged with an executable application or MIDlet, together with any needed resource files. Either the package, or optionally a JAR and JAD file, is downloaded to a remote user for execution on the target device. Using the application programming interface and the other downloaded files, the remote user can test the target device, analyze the results, and even modify the test conditions without recourse to the testing harness. The arrangement provides a capability for a party who is not privileged to know details of the testing harness to practically evaluate and modify the design-under-test using a standalone testing application.

Abstract: An electronic interactive book allowing a child to learn the pronunciation of various words. The book will be provided with a permanent or impermanent display onto which a plurality of words, phrases or sentences would be provided. The electronic book includes a microphone as well as a speech recognition unit for recognizing a word that the child pronounces. A highlighting device such as a light emitting diode or a means for illuminating a particular word in a manner different than the surrounding words would be engaged when the child correctly pronounces that word. The highlighting device has the ability to assist the child in the pronunciation of one of the words by verbally pronouncing a portion of the word, as well as simultaneously highlighting that portion. A visual display of the lip movements of an animated character would also assist the child in correctly pronouncing a particular word.

Abstract: A polymeric material with antistatic properties, characterised by comprising a dispersion of ions within a polymeric matrix containing heteroatoms.

Abstract: An apparatus for monitoring persons within predetermined areas has a plurality of tags irremovably applicable to persons and contain data characteristic of the person. At least one sensor for senses the presence of each person and is operationally connectable to each tag (2) via an ether. A supervision and control unit is operationally connected to the at least one sensor.

Abstract: The invention relates to an apparatus for shaping a light beam, having at least two optically functional boundary surfaces that are arranged one behind another in the propagation direction (z) of the light beam to be shaped, such that the light beam can pass through the at least two optically functional boundary surfaces one after another, and two groups of refractive or diffractive imaging elements that are arranged on at least one of the optically functional boundary surfaces, at least two of the imaging elements having different properties within at least one of the groups.

Abstract: A screening device which is particularly useful for separating solids from liquids when sewerage systems overflow. The device includes an inner apertured chamber and an internal brush arrangement for sweeping over the apertures to prevent clogging. A spray enables the apertured chamber to be washed after use.

Abstract: An intrusion detection system and method utilizing a power transmission cable connected to a source of radio frequency signals. A data transmission cable is associated with the power transmission cable and is provided with a plurality of radio frequency identification chips. The power transmission cable would induce an electromagnetic field within the data transmission cable allowing each of the RFID chips to transmit a signal during normal operation. However, if an intrusion occurs or the power transmission cable or data transmission cable is severed, the system according to the present invention, would be able to determine the exact point of intrusion based upon the signals received or not received from the RFID chips.

Abstract: A game device that includes non-uniformly shaped playing pieces that may be stacked onto an arrangement of multiple, base structures, the base structures having one or more substantially planar playing surfaces thereon, the playing pieces suitable for stacking on the playing surfaces in an unrestricted manner in accordance with rules for playing the game. The game may include a game board to which the base structures are securable.

Abstract: A vehicle (10) is used to lift the buried lid of a crypt and any soil or turf overlying the lid. The vehicle (10) has a mobile frame (14) which can be positioned over the lid. An attachment frame (11) is suspended from a subframe (12) within the mobile frame (14), the subframe (12) being adjustable laterally relative to the frame (14). The attachment frame (11) has winch cables (19) adapted to be connected to respective attachment fittings on the lid. Hydraulic cylinders (13) are used to raise the attachment frame (11) relative to the mobile frame (14), and thereby lift the lid and any overlying soil/turf. The raised lid can be transported while suspended from the vehicle (10), and subsequently returned for replacement on its crypt in a reverse procedure.
