Abstract: A target for grade metal tipped darts has a conductive rigid web made up of concentric rings intersecting spokes emanating from the second to the innermost ring.  The spokes define twenty sectors, while the rings define 4 segments within each sector. There are also two segments in the innermost and second to innermost rings.  Conductive blocks, made up of an aluminium or zinc cup having contacts protruding from its bottom and containing a rubberized cork insert, fill in the segments of the web.  Beneath each cup is a silicon foam cushion cut away between the contacts and a pad on a printed circuit board.  The pads are each connected to circuitry that senses when a dart hits an insert causing the corresponding cup to slide within the web and contact a pad.  The circuitry, by way of piezoelectric sensors, also determines if a dart has impacted on or near the target and checks to see if the target has polled a segment that indicates a hit on the target, failing which the target indicates that the dart missed the target.  The circuitry also senses the rotational orientation of the target and sets the basic scores of the segments accordingly, allowing the target to be periodically rotated to reposition segments in sectors of heavy use to sectors of lighter use.

Abstract: A liquid delivery device (10) particularly useful for delivering drugs in a liquid form, comprising a pressure-control chamber (18) having an electrolytic cell (22) therein and a reservoir (17) for the liquid separated from the pressure-control chamber (18) by a displaceable diaphragm (15). When sufficient pressure is generated within the pressure-control chamber (18) and reservoir (19), a second diaphragm (16) is raised to allow liquid to escape from the device, via an opening (26), through an outlet tube (20). The device (10) also includes a compensation chamber (19) which adjusts the rate of flow of the liquid in response to variations in ambient temperature and pressure. There is provided a pressure sensor (21) in the form of a sensor chamber (27) for immediately detecting an interruption in the flow of liquid from the device as an increase in pressure in the outlet tube (20) with respect to the pressure within the compensation chamber (19) and hence the reservoir (17). The means (21) for detecting an interruption in the delivery of liquid does not rely on the increase in pressure occurring as a result of continued gas generation.

Inventor: MARTIN-COUCHER JEAN-PAUL
IPC: B65B21/14
Filed: 1996-11-29
Abstract: The present invention relates to a pre-stretched film, and to apparatus and a method of applying outer packaging to packages and to loads, optimized as a function of the structure and in particular the shape of the package or the load, in particular a palletized load, and also as a function of the-transport and handling that the package or the load must be capable of withstanding without the outer packaging being dislocated.  According to the invention, a stretchable film is stretched over at least one roller of diameter that varies along its axis of rotation so as to form parallel longitudinal zones in the film that have different degrees of stretching. These zones make it possible, in particular, to track the external outlines of objects to be packaged and/or to provide locally-reinforced bonding, or on the contrary to present surfaces that are more relaxed.  The present invention applies in particular to packaging and grouping together loads that may optionally be palletized.  The main application of the present invention lies in grouping together bottles of beverages.

Title: System and method for encoding digital information in a television signal
Inventor: SIZER THEODORE II
IPC: H04N7/08
Filed: 1997-01-14
Abstract: Digital information is encoded in the video portion of a television signal such that "n" (n is an integer) bits of the digital information are carried by each successive frame in a group of frames. The digital information is encoded by modulating a carrier signal, using, for example, either amplitude shift keying (ASK) or frequency shift keying (FSK), and the modulated carrier is then added to the video signal selectively, only in portions of the television program that (a) are not likely to be perceptible by a viewer, and (b) are of sufficient intensity to transmit the data. The video signal including the encoded digital data, may be transmitted, in real time, to a television receiver, or recorded for later playback. In either event, at a receiver, when the video signal containing the encoded information is displayed on a screen, the image is sensed or "viewed" by a photo detector, the output of which is applied to a band pass filter having a center frequency that corresponds to the oscillator frequency(s) in the encoder. The filter output is thresholded or FM detected, so that the receiver can recover the encoded data. By appropriately including checks bits and synchronization patterns, the bit stream output from the decoder can be synchronized, and the original encoded data recovered. Advantageously, the frequency of the oscillator in the ASK or FSK encoder is chosen so that the energy added to the video signal is in a portion of the frequency spectrum that otherwise contains little energy. This makes the added digital data imperceptible to a viewer. If desired, the same data may be repetitively encoded in several groups of frames, so as to increase the redundancy and thus the reliability of the overall system.

Title: Tamper-proof device for lockingly attaching a piece of equipment to a support base
Inventor: THERER CLAUDE
IPC: E05B73/00
Filed: 1997-02-12
Abstract: A tamper-proof device is provided for lockingly attaching a piece of equipment such as a TV set or a microwave oven to a support base. It has a pair of rigid plates that are respectively connected to the piece of equipmentand the support base. One of the plates is surrounded by a flange which defines a closed area in which wedges are located to hook both plates together. The two plates are rigidly connected to each other by a screwable bolt that can be reached with a screw driver through a coaxial opening provided in the flange. A sleeve extends in between the head of the bolt and the opening. This sleeve can be closed by key-operated lock in order to prevent access to the bolt. The lock is free to rotate within the sleeve even when its latch is locked in outward position. Such prevents a theft from breaking the latch by forcing the lock into rotation in a cantilever fashion. A resilient plate is mounted within the closed area in such a manner as to extend radially close to the sleeve in order to contact the latch when the latch projects radially outwardly of the sleeve. This plate is resilient enough to let the latch flip over it if too much rotational force is applied to the lock within the sleeve.

Title: Detection of nucleic acids using g-quartets
Inventor: PITNER J BRUCE
IPC: C12Q1/68
Filed: 1997-08-07
Abstract: Oligonucleotides which form G-quartet structures have been found to be useful influorescence assays to detect a selected nucleic acid sequence. When one end of the oligonucleotide is labeled with a donor fluorophore and the other end is labeled with an acceptor dye, the folding of the molecule in the G-quartet structure brings the donor-acceptor pair into close proximity, allowing an interaction between the two labels which results in quenching of donor fluorescence or a change in other fluorescence properties which are the result of the interaction of two dyes in close proximity. The G-quartet structure unfolds upon hybridization to its complementary sequence, increasing the distance between the two dye labels. This results in decreased donor quenching or a change in another proximity-related fluorescence parameter. The associated increase in donor fluorescence intensity or the change in another fluorescence parameter may be monitored as an indication of the presence of a selected nucleic acid sequence. Alternatively, in some cases a decrease in acceptor fluorescence may be monitored as an indication of the presence of the selected nucleic acid sequence when the acceptor is also a fluorophore.
