Title: Spread spectrum time-division multiple access communication scheme
Inventor: SUN SONGSONG
IPC: H04B1/707
Filed: 1999-05-26
Abstract: A new DTX-MAC protocol is proposed for a cellular radio telecommunications system with many users. Several users are allowed to transmit packets within a time-slotted frame structure. Direct sequence spread spectrum technique is used to spread the packets, and all packets within the frame are spread using the same spreading sequence. The packets overlap, but each packet begins within a distinct slot of the frame. Each slot, or mini-slot, since it is much shorter than the packet, is dedicated to one of the mobile terminal users. Collisions between packets are prevented by appropriate selection of the duration of the mini-slot. Packets may be ARMs, user data, or both. A packet beginning within a mini-slot is assumed to be from the mobile terminal to which that mini-slot is dedicated.

Title: System and method for enhancing and separating biopotential signals
Inventor: GREENWALD SCOTT D
IPC: A61B5/0496
Filed: 1999-01-25
Abstract: Disclosed is an electrode array (i.e., "sensor") and a method for separating near and far-field signals. In one embodiment a horizontal array is used, and in an alternate embodiment a vertical array is used. The electrode array consists of two well-separated pairs of closely spaced electrodes (and a separate ground element). In a typical application of collecting a channel of EEG, "sensing"  electrodes are placed in standard locations (e.g., R and Ctr) with a ground electrode placed elsewhere on the head.  The voltage measured between the well-separated sensing electrodes is the far-field dominant (i.e., EEG-dominant) channel. Additional electrodes are placed near each of the two sensing electrodes. (The additional electrodes are immediately lateral to the existing electrodes in the horizontal array, and are immediately above the existing electrodes in the vertical array.) The voltages measured between the pairs of closely spaced electrodes are near-field dominant (i.e., EMG/EOG-dominant) channels. The EEG, EMG and EOG signals can be enhanced by uncoupling them by combining information from all channels. The sensor is connected to a monitor via a patient interface cable (PIC). The sensor contains additional circuitry at the connection site that is used by the monitor to identify the presence and type of sensor, and to configure the monitor to invoke the appropriate software that will apply the method of the current invention to collect and uncouple the EEG, EMG and EOG.

Patent CA-2296288-A1 (CA)
Title: Method for ammonia production
Inventor: WHITLOCK DAVID R
IPC: B01D11/04
Filed: 1998-07-16
Abstract: Ammonia is removed from synthesis gas, or other gaseous solvents by utilizing a sorbent to remove the ammonia followed by an in situ regeneration of the sorbent and recovery of the ammonia. The ammonia is sorbed onto the bed of sorbent, thereby producing a purified gaseous solvent. Regeneration is achieved by using at least a portion of the gaseous solvent which is then acted upon to increase its solvent capacity for the ammonia and passed through the sorbent in the opposite direction to desorb the ammonia from the sorbent to provide an increased solvent capacity gaseous solvent. The ammonia is then recovered from the increased solvent capacity gaseous solvent.
Patent CA-2298011-A1 (CA)
Inventor: HIPP JAMES E
IPC: E21B31/06
Filed: 1998-07-24
Abstract: An apparatus (10) for removing debris (D) from an oil and gas well is operable with fluid pressure that reciprocates a valving member (20) between upper and lower positions. The valving member (20) seals against a piston (30) in a lowermost position so that the fluid pressure can be used to move both valve member (20) and piston (30) downwardly. The valving member (20) has a valving member spring (28) that, when fully compressed, separates the valving member (20) and piston (30). Once the valving member (20) and piston (30) are separated, the piston (30) is no longer supported in the lowermost position because fluid pressure is relieved through the piston bore. A piston spring (40) then thrusts the piston (30) upwardly, causing it to pump fluid from a position outside the lower end of the tool body through an intake portion (14) into a cavity, pulling debris therewith. Pivoting flexible finger members (56, 57) or brushes are positioned at the lower end of the tool body and are moveable between open and closed positions for intaking the debris when in the opened position and for trapping debris when in the closed position. Staging magnets (63) are attached to the body of the tool. The flexible fingers (56, 57) or brushes move the debris from magnet (63) to magnet (63) in stages, finally reaching a storage area.

Title: Universal blow mold assembly
Inventor: TSAU TAR
IPC: B29C49/06
Filed: 2000-07-14
Abstract: A mold assembly has two mold half shells, corresponding mold half carriers, and a novel intermediate interconnecting member comprising a pair of ring shaped locating members. The locating members have an inner locating wall, preferably a stepped shoulder, that fits into a recessed slot in the outer wall of the mold shells. The locating members have an outer wall that fits into a recessed slot in the inner wall of the mold half carriers. The inner and outer locating walls of the locating members are vertically positioned relative to each to determine the vertical registry of the mold shell to the mold carrier. The assembly utilizes a base insert located below the mold half shells having an inner base wall that defines the shape of the base of the container. The assembly has an interchangeable pedestal spacer positioned below the base insert having a thickness chosen relative to the vertical registry defined by the intermediate interconnecting member. By utilizing intermediate interconnecting members of differing relative vertical positioning of the inner and outer locating walls, universals mold shells and mold carriers may be used for containers having differing neck heights whereby the neck height adjustment is accommodated by changing the intermediate interconnecting member. Consequently, quick changes in the assembly can be made by replacing a relatively less expensive interconnecting ring members which are part of the standard spare parts of the mold carrier and pedestal spacer as compared to making new more expensive mold shells.
