Title: A data segmentation method in a telecommunications system
Inventor: RINNE MIKKO J
IPC: H04L12/56
Filed: 1999-10-05
Abstract: In a telecommunications system a larger higher layer data unit (SDU) is segmented into smaller segments on the lower layer (RLC).  A segmentation length information is used to indicate the lengths of the segments in a lower layer protocol data unit (PDU). Specific values of segmentation length information are employed to indicate, when necessary, special information about the upper layer data unit (SDU), such as whether the upper layer data unit ends in the current data segment in the lower layer PDU or continues to the next lower layer PDU. This information is needed in the receiver to correctly assemble the segmented data.

Title: Delivery mechanism for implantable stent
Inventor: BROOKS CHRISTOPHER J
IPC: A61F2/95
Filed: 1999-09-30
Abstract: A delivery mechanism for an implantable stent which provides a high mechanical advantage to the surgeon and convenient operation so as to facilitate smooth withdrawal of an outer catheter sheath following placement of the stent in the desired location within the patient's vessel. Preferred embodiments include a moving rail actuated by a V-shaped lever, a hydraulic actuator, a rack and pinion drive, and a power screw system. The delivery mechanism has a movable member that is attached to the outer catheter sheath so that actuating the mechanism results in an incremental movement of the moveable member, which in turn results in an incremental movement of the outer catheter sheath. Once the outer catheter sheath is retracted from the stent, the stent is deployed into the patient's vessel and the remaining parts of the mechanism, including an inner tube, an atraumatic tip, and a stabilizing element, are easily removed.

Patent CA-2352551-A1 (CA)
Title: Crop material processor
Inventor: HRUSKA KEVIN
IPC: A01F29/12
Filed: 1999-09-17
Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalls of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.

Filed: 2000-11-14
Abstract: Data is recorded in a first part PA1 in accordance with a signal format same as that of an existing CD at the lower limit (1.5 µm) of an allowable value of a track pitch and the lower limit (1.2 m/sec) of a linear velocity. As a result, the data for the maximum regeneration time (74.7 min) can be recorded in the first part PA1. An existing CD reproducing apparatus can reproduce the audio data recorded in the first part PA1 with no problem. Moreover, compressed and encrypted audio data is recorded in a second part PA2 at a single density or a double density. The single density represents a recording density same as that of an existing CD and the double density represents a density two time larger than the single density. Furthermore, the audio data recorded in the second part PA2 is charged when reproduced in order to protect copyrights. The format of the data recorded in the second part PA2 uses the format of a CD-ROM.

Title: Chirp compensated mach-zehnder electro-optic modulator
Inventor: GATES JOHN VANATTA II
IPC: G02F1/035
Filed: 2002-03-19
Abstract: A Mach-Zehnder electro-optic modulator is formed that exhibits significantly reduced chirp by utilizing an RF electrode that covers a first waveguide arm in a first region of the modulator and covers the second, remaining waveguide arm in a third region of the modulator (with a second, intermediate region used as a transition area for the electrode). Moving the electrode from one waveguide to the other allows for the chirp created in the third region to essentially "null out" the chirp that accumulated along the first region. Modulation of the optical signal is maintained in the presence of the "electrode switching" by inverting the domain of the optical substrate material in the third region of the modulator.

Title: Method for decreasing heat transfer from production tubing
Inventor: COX DON C
IPC: E21B36/00
Filed: 2002-04-02
Abstract: A method for retarding temperature loss of fluid being produced in a well employs a fluid of low thermal conductivity in the tubing annulus.      The tubing annulus extends between the production casing and the production tubing. It extends from a packer at the lower end of the tubing annulus to a wellhead. The fluid in one case is low density gas created by a partial vacuum. A vacuum is drawn on the tubing annulus to reduce the air density, which in turn reduces the amount of heat that convection currents can carry. In another example, the tubing annulus fluid is viscous hydrocarbon liquid. The hydrocarbon liquid also has a low thermal conductivity. Heat is supplied to the fluids being produced through the tubing annulus by a heater cable that extends into the well.

Title: Method for performing wireless mobile instant messaging
Inventor: BHUTA MAHESH
IPC: H04L12/58
Filed: 2001-05-24
Abstract: A first mobile station (102) is used to send a message to a second mobile station (118). The user of the first mobile station designates the second mobile station as the target, and composes a message either by recording speech or entering a text message on the first mobile station. The mobile station then transmits the message and target identifier to a fixed equipment network including an EBTS (104), BSC (106) and a mobile data gateway (108). The MDG uses dispatch calling resources to route the message without queuing or storing the message by obtaining the present location of the second mobile station from a dispatch visit location register (112). The MDG then routes the message similarly to setting up a dispatch call between the first and second mobile stations.

Title: Apparatus and method to improve resolution of infrared touch systems
Inventor: DEACON JOHN
IPC: G06F3/042
Filed: 2000-12-04
Abstract: A touch system using a plurality of infrared ("IR") transmitters and receivers, and a method of determining with increased resolution the location of a touch between the IR transmitters and receivers using on-axis and off-axis detection are disclosed. The inventive touch system and method use, in conjunction with the on-axis and off-axis detection, a coarse and fine sweep of the transmitters and receivers to increase the resolution of identified touch location. The method of determining a touch location involves selection and activation of particular off-axis infrared transmitter and receiver pairs determined from a triangulation interdependence between the x and y coordinates. The increased resolution of the identified touch location is achievable using the inventive system and method without the need for an increased number of IR transmitters and receivers and without the need for higher speed processing capability.
