Title: Pak mont toothbrush
Inventor: AKRAM ASHFAQ
IPC: A46B9/04
Filed: 1999-06-23
Abstract: For the use of toothbrush to clean the teeth, it is recommended that the head of the toothbrush should be placed beside teeth with the bristle tips at a 45 degree angle against the gum line. In PAK MONT Toothbrush, rectangular head with rounded edges contains bristles in five rows.      They are classified as:      Bristles of outer row.      Bristles of intermediate row.      Bristles of central row. Bristles of all rows Do not have the same length. Instead, inclined cutting of bristles making a 45 degree angle with horizontal plane is the unique characteristic of PAK MONT  toothbrush. Tuft of each row is not rounded end. Instead, it has TAPERED End which is 2nd important characteristic of PAK MONT toothbrush as shown in figure 4. In PAK MONT tooth brush, there is passage for flow of sodium flouride/mouthwash through micro holes located on Head around the bristles. The passage runs along neck and handle. The flow of Sodium flouride/mouthwash through head of brush is the 3rd unique feature giving this tooth brush a NEW PRODUCT.

Title: Oral anchorage
Inventor: CAMPBELL DUNCAN FRASER
IPC: A61F5/058
Filed: 1998-05-11
Abstract: The present invention provides an intra-oral anchorage which comprises a flexible belt that extends around and between the teeth of a patient. The belt has locking means fixed thereon to receive a free end portion of the belt and lock said portion against retraction therefrom. The locking means is in the form of a buckle. The intra-oral anchorage of the present invention can be used to hold a jaw in a fixed position, in the case of a broken jaw for example. It offers ease of application and therefore a reduction in the cost of surgery as well as eliminating the risk of "needle stick" injury inherent with cutting and bending multiple ends of wire. It causes less gum damage in placement and removal, which is similarly easier, faster and less uncomfortable for the patient.

Title: Method and apparatus for converting a wideband if signal to a complex (quadrature) baseband signal
Inventor: MYERS RICHARD H
IPC: H04L27/233
Filed: 1998-07-08
Abstract: A wideband radio receiver provides a complex baseband signal by normalizing an IF signal using a limiting amplifier. The normalized IF signal is applied to a complex sampling circuit to provide normalized I and Q components. The limiting amplifier provides an RSSI signal representing the received signal amplitude. The RSSI signal, which is sampled at the same rate as the normalized IF signal, is combined with the normalized and Q components, to provide I and Q components of the baseband signal.

Patent CA-2302877-A1 (CA)
Inventor: CHU IVAN K
IPC: G01N33/68
Filed: 2000-03-29
Abstract: A strategy for semiautomatic sequencing of argentinated (silver-containing) oligopeptides is described. The method of sequencing described is based on a search algorithm that identifies a triplet peak relationship in a product ion spectrum of the [M + Ag]+ ion of an oligopeptide. The ions that constitute a triplet are [b~ + OH + Ag] + , [b~-H + Ag]+ , and [a~ - H + Ag]+ , which are separated by 18 and 28 ~/~ units, respectively. The difference in the ~/~ values of adjacent triplets identifies the residue that is "cleaved". Observation of the [y~ + H + Ag]+ ion containing the cleaved residue confirms the assignment.

Inventor: NGYUN GREG
IPC: G11B17/043
Filed: 1998-09-08
Abstract: A cartridge for a disk drive has a rigid shell with a keying ear (22) and two keying grooves (24, 25). The keying ear is located on the rounded front at one corner between the top and bottom surfaces of the cartridge shell. The ear cooperates with a projection located in the drive along the drive receiving slot. The keying grooves are along the top and bottom edges of one side of the cartridge. These groves mate with projections on the cartridge receiving slot in the drive. One of the grooves extends deeper into one planar surface of the cartridge than the other groove. Both keys prevent insertion of the cartridge with any other orientation of the cartridge than the correct orientation.

Patent CA-2328078-A1 (CA)
Inventor: BALCK KENNETH
IPC: H04W36/06
Filed: 1999-03-05
Abstract: The present invention dynamically increases the capacity of a cellular radio communications system to meet temporary high traffic demands effectively and economically. The current traffic load at a particular base station cell area is determined (14). If the determined traffic load exceeds a threshold (16), a higher rate traffic channel over which a dual rate mobile station is communicating is handed over to a lower rate traffic channel available in that cell area (18). A list is maintained for those dual rate mobile stations currently assigned to higher rate traffic channels. Before making the handover from the higher rate traffic channel to the lower rate traffic channel, it is determined whether a handover is permitted. If so, the intra-cell handover is preferably made to a traffic channel which is currently already supporting another lower rate call. Otherwise, any available lower rate traffic channel is assigned. At call setup, if the current traffic load in the cell area exceeds the threshold, a call request involving a dual rate mobile station is assigned a lower rate traffic channel (20). If the traffic load in the cell area decreases, a call intitially set up or subsequently handed over to a lower rate channel because of high traffic load may optionally be handed over to a higher rate channel (17).
