Title: Adjustable truck bed divider for stabilizing cargo
Inventor: BERNARDO RICHARD GREGORY
IPC: B61D45/00
Filed: 2002-03-28
Abstract: A truck bed cargo barrier for use with a truck bed for stabilizing cargo items longitudinally and laterally. The cargo barrier is slidable relative to the front and back of the truck bed along a track system. The cargo barrier may be locked in a user specified position along the track system to accommodate the size of the load being carried forming a divider, or may be flipped up into a temporary storage position for linear cargo exceeding the length of the bed. Tie down brackets for bungee cords are adjustably attached to the barrier frame to secure cargo laterally. A barrier panel is connected to laterally adjustable, rigid side plates, each including two spaced apart wheels that ride on a pair of longitudinal tracks on the side walls of the truck bed. The spaced apart wheels firmly secure the barrier panel in a vertical position. A manual actuator permits manual positioning of the barrier panel along the bed frame front to back.

Title: Measuring viral reverse transcriptase activity
Inventor: REYNOLDS THOMAS R
IPC: C12Q1/68
Filed: 2001-06-21
Abstract: In clinical settings as well as in a drug-discovery context, the impact of an agent that may affect reverse transcriptase (RT) can be measured and even quantified by bringing a sample, which may contain an RT, into contact with an RNA template, a primer complementary to the RNA template, and appropriate oligonucleotide-specific primers, under conditions such that they react, in the presence of RT, to form a cDNA product in inverse proportion to the effect of the agent. The amount of any resultant cDNA product then can be measured.  The approach is readily implemented as a real-time, quantitative kinetic assay for RT activity.
Patent CA-2384988-A1 (CA)
Title: Crankpin grinding method
Inventor: THORPE CHRISTOPHER SHAUN
IPC: B24B49/00
Filed: 2000-10-26
Abstract: A method is described for grinding a crankpin of a crankshaft using computer controlled wheelfeed and headstock drives (44,30,24). During a final grinding step leading to finish size the cutting force is maintained on the wheelhead (38) to keep the wheel (34) and pin under a moderate constant load and the rotational speed of the headstock drive (24) is reduced. This serves to prevent bounce and chatter marks appearing in the surface of the pin. The rotational speed is typically in the range of 1 to 5 rpm. During the final step of grinding each pin, the wheelfeed is adjusted so as to remove a sufficient depth of material during a single rotation of the crankshaft, to bring the crankpin to finish size. In order to determine the depth of cut required, each pin is gauged before the final grinding step is performed, to determine the depth of cut necessary to achieve finish size.

Title: Manipulating header fields for improved performance in packet communications
Inventor: AYADURAI VICKNESAN
IPC: H04L12/801
Filed: 2000-08-11
Abstract: In packet communication paths (18) that include header compression, header fields of packets to be communicated are altered. The alteration of the header fields (14) does not disturb their functionality, and its transparent to the header compression scheme of the packet communication path (18). The altered header fields (14) are provided for compression by the header compression scheme, resulting in improved performance of the header compression scheme.  Performance improvements can also be achieved in packet communication paths (18) that do not use header compression, by violating the integrity of header fields in packets to be transmitted over the packet communication path (18).

Title: Dynamic jitter buffering for voice-over-ip and other packet-based communication systems
Inventor: LANZAFAME CHRISTOPHER
IPC: H04Q11/04
Filed: 2002-07-15
Abstract: A variable-size jitter buffer is used to store information associated with a voice signal, facsimile signal or other received signal in a receiver of a packet- based communication system. The receiver determines an appropriate adjustment time for making an adjustment to the size of the buffer based at least in part on a result of a signal detection operation performed on the received signal. For example, in the case of a received voice signal, the determined adjustment time may be a time at which a state machine associated with a speech detector is in a "no speech" state. If the actual buffer size at the determined adjustment time is not within a designated range of a target computed at least in part based on one or more jitter measurements, the buffer size is adjusted at the determined adjustment time, e.g., by an amount representative of the difference between the actual buffer size and the target. The invention provides low-delay and low-complexity jitter buffering particularly well suited for use in an Internet Protocol (IP) receiver of a voice-over-IP system.
