Abstract: A condition-adaptable fishing net designed to catch more fish. The fishing net includes a single, large panel of netting having a main, light color capable of blending in water under certain water and lighting conditions. Disposed randomly over the panel of netting are a plurality of various sizes and shapes of colored areas, each having a color selected from a group of colors, all capable of blending in water under different water and lighting conditions. By randomly creating different colored areas over the net panel, what fish will believe to be holes or barrier free areas, appear randomly in the panel of netting. During use, the different colored shapes randomly appear as holes or barrier free areas in the panel of netting through which the fish then attempt to swim, thus becoming entangled in the net.

Patent CA-2256962-C (CA)
Inventor: NORTRUP EDWARD H
IPC: H01J61/54

Granted: 2008-01-29
Abstract: A starting aid for a metal halide discharge lamp. An arc discharge tube is positioned in a hermetically sealed jacket. The jacket contains a partial pressure (e.g., 400 torr nitrogen) of a gas that will aid in starting the discharge and one of the arc tube lead-ins has an electrical conductor affixed thereto and exposed to the partial pressure of the gas. An outer conductor extends on the outside of the jacket and is electrically connected to the other lead-in. When voltage is applied to the electrodes a capacitive coupling takes place between the inner conductor and the outer conductor which generates a discharge that causes a breakdown in the arc generating and sustaining medium within the arc tube and causes the lamp to start.

Title: Nucleic acid amplification oligonucleotides with molecular energy transfer labels and methods based thereon
Inventor: NAZARENKO IRINA A
IPC: C12Q1/68
Filed: 1997-07-15
Granted: 2003-03-18
Abstract: The present invention provides labeled nucleic acid amplification oligonucleotides, which can be linear or hairpin primers or blocking oligonucleotides. The oligonucleotides of the invention are labeled with donor and/or acceptor moieties of molecular energy transfer pairs. The moieties can be fluorophores, such that fluorescent energy emitted by the donor is absorbed by the acceptor. The acceptor may be a fluorophore that fluoresces at a wavelength different from the donor moiety, or it may be a quencher. The oligonucleotides of the invention are configured so that a donor moiety and an acceptor moiety are incorporated into the amplification product. The invention also provides methods and kits for directly detecting amplification products employing the nucleic acid amplification primers. When labeled linear primers are used, treatment with exonuclease or by using specific temperature eliminates the need for separation of unincorporated primers. This "closed-tube" format greatly reduces the possibility of carryover contamination with amplification products, provides for high throughput of samples, and may be totally automated.

Filed: 1998-02-05
Granted: 2004-11-23
Abstract: An apparatus is disclosed for providing more uniform lighter spark wheel actuation. Uniform actuation is facilitated in the apparatus according to the invention by reducing the formation of deep grooves and high ridges in the flint.

Abstract: In a two-wire arc spray extension two metal wires are guided into contact, and a gas cap is affixed to a gun body. The feeding wires receive an arc current to effect an arc and thereby molten metal at the wire tips. The gas cap has a plurality of orifices therein that receive pressurized gas to generate gas jets. The orifices are disposed with substantially equal spacing arcuately such that the jets are directed with a radially inward component toward the tips to effect atomization of the molten metal into a spray stream. The orifices have axes that are offset forwardly and tangentially from radial so as to create a vortex flow such that the spray stream is effected in the form of a conical fan. Insertion of the spray stream centrally into a hole can effect a coating circumferentially on an inside surface of the hole.

Title: Methods and apparatus for adjusting power in an optical signal, for providing a seamless optical ring and for providing a bidirectional equalized amplifier
Inventor: WAN PING WAI
IPC: H04B10/24

Granted: 2011-08-09
Abstract: A method and apparatus for adjusting power in an optical signal are disclosed and a bidirectional equalized amplifier for providing bidirectional equalization, employing the apparatus and method is disclosed. Use of the method and apparatus to form a seamless ring in an optical network is also disclosed. The method of adjusting power involves splitting an input composite signal into respective drop signals in separate wavelength bands with a splitter. An attenuator attenuates the drop signals to produce attenuated drop signals. A combiner combines the attenuated drop signals to produce a first output composite signal in which the power is equalized. The bidirectional equalized amplifier involves a first apparatus as described above for splitting, attenuating and then combining signals in respective wavelength bands of an input composite optical signal, to produce a first output composite signal. An amplifier amplifies the first output composite signal to produce an amplified first output composite signal which is passed through a reverse path in a second apparatus of the type described above to a second input port of the second apparatus, for transmission on an optical medium, while selectively splitting, attenuating and then combining signals in respective wavelength bands of a second input composite optical signal, received at the second input port of the second apparatus to produce a second output composite signal. The second output composite signal is then amplified to produce an amplified second output composite signal which is then passed through a reverse path in the first apparatus to the first input port of the first apparatus for transmission on an optical medium.

Abstract: In a method and a device for transmission of S+P transform coded digitized images a mask is calculated by means of which a region of interest (ROI) can be transmitted lossless whereby the ROI can be transmitted and received lossless and still maintaining a good compression ratio for the image as a whole. This is possible since no or very few bits can be used for the remaining part of the image.  The calculated mask can also be used for transmitting the coefficients needed for a lossless region of interest during any stage of the transmission.

Abstract: Given this relay, a coil body (1) is formed as base member by injection molding, whereby at least one fixed contact carrier (3, 4) as well as a contact spring/terminal pin (5) and coil terminal pins (9, 10) are pushed into the mold in the form of wire sections of drawn semi-finished goods and are co-injected. Optionally, the core (16) can also be embedded into the material of the coil body (1). As a result thereof, no joining processes thereby occur wherein plastic particles could be scraped off and later proceed onto the contacts. In this way, the assembly of all terminal parts ensues in one cost-beneficial step in the injection mold with the least possible employment of material, namely as a result of half- finished wire goods that are cut waste-free.
