Abstract: This invention is an orthodontic appliance (10) for assisting in properly positioning teeth within the mouth of an individual which is capable of fitting various mouth and tooth sizes. The appliance (10) includes a labial-buccal flange (12), a lingual flange (14) spaced from the labial-buccal flange (12), both of which define a generally U-shaped configuration in the occlusal view, and an isthmus (16) interconnecting the two flanges (12, 14). At least one tooth through (32, 40) is defined between the labial-buccal flange (12), and the lingual flange (14) for receiving either an upper or a lower row of the individual's teeth. The appliance (10) includes no individual tooth sockets but instead utilizes pressure applied by the labial-buccal flange (12), the lingual flange (14), the relative angles, and material thicknesses to properly position the teeth. The appliance (10) is capable of fitting mouths and teeth of various sizes because it includes no individual tooth sockets.

Patent CA-2319280-A1 (CA)
Inventor: DELAVAUX JEAN-MARC PIERRE
IPC: H04B10/296
Filed: 2000-09-14
Abstract: A high power optical amplifier with multiple outputs is formed by using a preamplifier stage (such as an EDFA), followed by a power splitter/WDM router (forming the desired number of M separate optical outputs). Each preamplified/split output is then separately amplified in a high power amplifier, such as a erbium-ytterbium co-doped amplifier. The power loss associated with the signal splitting thus occurs prior to imparting the high power gain onto the optical signals, allowing for a plurality of high power optical outputs to be formed.

Inventor: JAIN MAHENDRA KUMAR
IPC: C12Q1/68
Filed: 1999-03-05
Abstract: A method is provided for identifying polycationic, peptide-like compounds characterized by antibacterial activity against gram negative bacteria. The method takes advantage of the induction of hyperosomotic stress without leakage of cytoplasmic content. The method involves determining whether the compound has the ability to produce phospholipid exchange betwen the lipid bilayers in conjunction with the induction of the osmotic stress response in the target cell. Determining the induction of the osmotic stress response is effected using a bioluminescent detector organism having a osmY-LUX gene fusion.

Inventor: THUDIUM KENT
IPC: C12N15/65
Filed: 1999-04-13
Abstract: A noncloning method for expressing a gene of interest in a mammalian host cell is disclosed. The invention utilizes three basic individual elements: 1) a promoter element; 2) at least one gene of interest; and 3) a selectable marker cassette which includes in 5' to 3' order, an internal ribosome entry site ("IRES"), at least one gene coding for a selectable marker, and a transcription termination sequence. The three individual elements are cotransfected into a mammalian host cell where they become operably linked such that expression of the selectable marker gene(s) necessarily requires coexpression of the gene of interest.

Title: Device for rotatably positioning a camera or similar article about two orthogonal axes
Inventor: HOVANKY THAO D
IPC: F16M11/12
Filed: 1999-05-26
Abstract: A positioning device (100) is provided for rotatably positioning a camera (102) or other article about orthogonal rotational axis by a yoke (106). The yoke (106) is in turn rotatably coupled to a base assembly for rotation of the yoke about a vertical axis. Rotation of the camera about the horizontal and vertical axes is respectively effected by first and second voice coil actuators (110 and 112), each comprising a pair of magnets and at least one coil to which current is supplied. The amplitude and direction of the current supplied to the coil determines the speed and direction of rotation of the camera. The second voice coil actuator preferably includes a coil assembly comprising two opposed coils. This design overcomes the angular range limitations associated with prior art voice coil actuator and enables rotation of the camera about an extended angular range. The device can be advantageously utilized for adjustment of pan and tilt angles of a video camera in a conferencing system.
Patent CA-2332017-A1 (CA)
Title: Liquid disrupter with reduced recoil
Inventor: ELSENER JOSEF
IPC: F42B33/06
Filed: 1999-06-09
Abstract: The disrupter (16) includes an elongated hollow barrel (18) having a cylindrical inner chamber (20), a closed rear (26) end and an opened front end (22), the latter closed with a front frangible seal (38). A  channel member (46) partly surrounds an intermediate portion of the barrel, and is securely attached thereto. A pair of recoil channels (76, 78) extend from the barrel inner chamber, radially outwardly and rearwardly through the barrel and the channel member, and are linked to rearwardly oriented recoil tubes (52, 54) which have opened rear end portions (60, 62) closed with rear frangible seals (64, 66). In use, a cartridge (90) including an explosive charge (88) is to be inserted in the barrel inner chamber at its rear end, and the barrel, recoil channels and recoil tubes (52, 54) are to be filled with water. The frangible seals (38, 64, 66) prevent the water from leaking out of the disrupter while it is positioned near a bomb to be deactivated. A trigger (36) is linked to the disrupter, and more particularly to the cartridge, to remotely detonate the explosive charge. Upon the explosive charge being detonated, a portion of the water is propelled and ejected at high velocity out through the barrel front end, rupturing the front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components, Another portion of the water is redirected through the side recoil channels and recoil tubes, rupturing the rear frangible seals, to be ejected rearwardly out of the disrupter. The recoil created by the detonation of the explosive charge which ejects the water through the barrel front end, is at least partially counteracted by the water being laterally and rearwardly redirected to be ejected rearwardly out through the recoil tubes. The recoil tubes have at their rear ends (60, 62) transverse blades (73, 74) for wide angle dispersal of the fluid jet being ejected rearwardly.

Title: Address generator and address generating method for use in a turbo interleaver/deinterleaver
Inventor: LEE YOUNG-HWAN
IPC: H03M13/27
Filed: 2000-04-03
Abstract: An address generator and an address generating method are described. In the address generator, a first counter counts a plurality of clock pulses, generates a first group count, which indicates one of the group addresses of an interleaves block, at each clock pulse, and generates a carry after counting a predetermined number of clock pulses. A second counter receives the carry from the first counter, counts the carry, and generates a position count indicating one of the position addresses in each group. If the group count is one of the unavailable group count values representative of unavailable groups, or the group count is one of partially unavailable group count values representative of groups having both available and unavailable position addresses and the first position count is one of unavailable position count values representative of unavailable position addresses, a controller controls the first and second counters not to output the first group count and the first position count. A  bit reverser reverses the first count. An operating device subjects the group count and the position count to an LCS (Linear Congruential Sequence) recursion formula and generates result bits. A buffer stores an available address formed out of the reversed bits received from the bit reverser and the result bits received from the operating device.
