Abstract: A method and apparatus for airborne geological surveying and similar applications. Typically a large loop antenna (1) is placed on the surface of an area of ground (2) which is to be surveyed and a transient current pulse is caused to flow in the anten-na. An airborne receiver (5) is used to detect the electromagnetic field and TEM (Transient Electromagnetic Method), MMR (Magnetometric Resistivity) and MIP (Magnetic Induced Polarisation) analysis techniques are used to determine the survey re-sults. The receiver (5) may be supported on an aeroplane (4), balloon, helicopter or the like and be adapted to store collected in-formation onto a storage device for later analysis if desired.

Granted: 2004-07-06
Abstract: In a passive identification apparatus for identifying a predetermined individual member of a television viewing audience in a monitored viewing area, a video image of a monitored viewing area is captured. A template matching score is provided for an object in the video image. A Eigenface recognition score is provided for an object in the video image. These scores may be provided by comparing objects in the video image to reference files. The template matching score and the Eigenface recognition score are fused to form a composite identification record from which a viewer may be identified. Body shape matching, viewer tracking, viewer sensing, and/or historical data may be used to assist in viewer identification. The reference files may be updated as recognition scores decline.

Abstract: The invention is concerned with a low cost postage value generating apparatus wherein the number of postage imprints are determined rather than an accounting of the postage value.  The apparatus has two movable print heads each having a single value font.  This device is able to print multi-values by using multiple impressions of the two print heads.  Because of this, the number of imprints gives a representation of the total postage value dispensed.

Title: Self testing circuit breaker ground fault and sputtering arc trip unit
Inventor: MACKENZIE RAYMOND WARREN
IPC: H02H1/00
Filed: 1994-09-15
Granted: 2003-12-09
Abstract: Ground fault trip units for circuit breakers are tested by a passive test circuit which includes a test conductor passing through the current transformer sensing coil(s), and a test switch which selectively connects the test conductor in a loop which simulates a neutral-to-ground fault. In a dormant oscillator ground fault test circuit, the test conductor loop passes through both sensing coils. When the neutral-to-ground detector is combined with a sputtering arc fault detector sharing a common sensing coil, testing of all the components is accomplished by adding an additional test circuit which injects pulses derived from the line conductor into the sensing coil secondary, or which alternatively, connects a capacitor charged from a DC supply across the sensing coil secondary. Either of these alternative test circuits generates the successive events needed to produce a sputtering arc trip.

Abstract: Apparatus for selecting predetermined ones of packets of signal components, from a signal stream of packets includes a control device, responsive to user selection and a transmitted program guide, for determining packet identifier codes, SCID's, for respective program signal components. The respective component SCID's are stored in programmable registers. SCID's, from respective packets in the signal stream, are successively loaded into a further register. Comparators which are associated with the programmable registers, compare the stored SCID's with the SCID's from packets in the signal stream. Output signals from the respective comparators control the utilization of the respective signal component packets in the signal stream. Programming of SCID's in the respective programmable registers is performed according to a schedule to preclude undesired data inadvertently being accepted by the system.

Title: Electronic thermometer with audible temperature rise indicator
Inventor: FUJIKAWA TOYOHARU
IPC: G01K7/42
Filed: 1995-12-20
Granted: 2003-09-23
Abstract: An electronic thermometer for measuring body temperature has a temperature sensor for detecting a sensed temperature and for producing an output indicative of the sensor temperature and a temperature rise detector for detecting whether the sensed temperature is rising. If the sensed temperature is rising, the temperature rise detector produces a temperature rise signal. The thermometer is provided with circuitry for generating an audible signal in response to the temperature rise signal. The device thus audibly indicates that the sensed temperature is rising and that the temperature measurement is proceeding normally. The temperature sensor includes a thermosensitive oscillator, the oscillating frequency of which changes depending on a change in its temperature, and a reference oscillator for generating a reference signal. A temperature counter counts an output signal from the thermosensitive oscillator on the basis of the reference signal. A data hold unit holds a maximum value of data on the measured signals in the temperature counter. A comparator compares data in the data hold unit and the new data in the temperature counter to thereby rewrite the data in the data hold unit with the new measured data in accordance with the result of the comparison by the comparator. The temperature rise detector detects whether the measured temperature is rising in accordance with the result of the comparison by the comparator. A temperature rise detection signal from the temperature rise detection device drives a sound generator to inform that the measured temperature is rising.

Abstract: A ball valve having a valve body defining a ball valve chamber and having a longitudinal axis defined by inlet and outlet passages.  A ball valve element is rotatably disposed in said valve chamber.  The ball valve element has a diametrically disposed fluid passage and is operatively connected to a control lever for rotating the ball valve element between a closed position and an open position.  A basket strainer is removably mounted in the ball element passage in the ball valve element.  The ball valve is provided with an internal pilot fluid flush passage that connects an inlet port to the ball valve chamber, and a pilot fluid flush discharge port and discharge valve that communicate with the ball valve chamber.  A flow control plug valve is movably mounted in the internal pilot fluid flush passage for selective allowing or preventing fluid flow therethrough.  When the ball valve element is rotated to a closed position, the flow control plug valve may be moved to an open position to allow upstream fluid to flow through the inlet port and internal pilot fluid flush passage and into the ball valve element chamber and through the basket strainer and out the pilot fluid flush discharge port, to reverse flush out debris captured by the basket strainer.

Abstract: A liner (30) of polyethylene is pulled through a die (36) and through the pipe (10) and allowed to revert to the internal diameter of the pipe. The force of pulling is half the yield strength of the liner or less. The die has an entry; an throat and an exit; the entry decreasing in diameter towards the throat and the exit increasing in diameter away from the throat. The liner has a maximum diameter before the die, a minimum diameter in the die and intermediate diameter after the die. The liner bending inwards before first contacting the die at the entry, then continuously bending through its minimum diameter as it passes the throat and then undergoing die swell resulting in said intermediate diameter. The throat is defined by the merger in a continuous curve of a radius joining the entry and a radius joining the exit. The entry is convex between where the liner (30) first contacts the die after bending inwardly and said throat.

Granted: 2000-12-12
Abstract: An arrangement for generating and receiving standard telecommunications network signals on behalf of a terminal not equipped to generate or receive such signals. A controller shared by a plu-rality of such terminals receives signals from these terminals over a permanent virtual circuit (PVC) and uses the information received over the PVC to perform signaling. In a specific embodiment, the terminals are set top boxes, connected to a video cable, for controlling television sets. The controller controls signaling for establishing con-nections between the set top box and a video ven-dor system, and tunes the set top box to receive signals on the proper channel. Advantageously, such an arrangement significantly reduces the cost of the set top box while still allowing for a highly flexible signaling arrangement to the video vendor system.
