Patent CA-2298553-A1 (CA)
Inventor: BERTHON-JONES MICHAEL
IPC: A61B5/087
Filed: 1997-09-23
Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor receives an airflow signal from a pressure transducer coupled to a port at a mask.    The microprocessor controls a servo that in turn controls the fan motor and thus the pressure of air delivered by the blower. The blower is coupled to a subject's mask by a conduit. The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

Title: Orthogonal frequency division multiplexing based spread spectrum multiple access system using directional antenna
Inventor: LI JUNYI
IPC: H04W16/30
Filed: 2000-02-24
Abstract: A base station within a cell of an orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access system employs sectorization as a way to reduce the intercell interference. The cell is sectorized from a transmission point of view by the directionality of the downlink antenna, and the OFDM tone set employed in each cell is correspondingly sectorized, i.e., each sector in the cell is allocated a set of tones within a sub-band of the available frequency bandwidth for use when transmitting into that sector. The sub-bands assigned to each sector are periodically changed, or "hopped", among the available sub-bands within the totally available bandwidth. Such sub-band hopping is a so-called "slow" hopping, in that it is not performed on a symbol-by-symbol basis but instead occurs only after more than one symbol has been transmitted in a sector on tones within the sub-band. Each sector employs its own pilot signal, which is assigned one or more tones within the sub-band currently employed by that sector. Similarly, for the uplink, the base station may employ a directional receiver antenna. Preferably, the mobile terminal only transmits on a tone that is within a sub-band that is allocated to the sector in which the mobile terminal is located. This, sub-band, however, need not correspond to the same location within the bandwidth as the sub-band used by the downlink to communicate with the mobile terminal.

Patent CA-2301541-A1 (CA)
Inventor: PETROSIAN FREDERICK N
IPC: H01Q21/22
Filed: 1998-08-20
Abstract: The present invention provides for a method and apparatus for compensation of diffraction of beam of an antenna system. In the preferred embodiment, the antenna system is a phased array antenna (figure 6). The present invention does so by controlling the phase front. The phase front is controlled by distributing frequencies such that the value of the frequency for a given emitter (SBM) is proportional to the distance of the emitter from the center of the antenna system. In one embodiment of the invention, the value of the frequency for a given emitter is linear, square or otherwise, to the distance of the emitter from the center of the antenna system. A phase front formed by the time spectrum is summed with a phase front created by diffraction divergence compensation.
Patent CA-2302684-A1 (CA)
Inventor: VAN DEN BRINK CHRISTOPHER RALP
IPC: B62K5/027
Filed: 1998-09-16
Abstract: The invention relates to a vehicle (1) provided with a frame (2) having a front frame pan (3) and a rear frame part (4) which can tilt with respect to one another. The vehicle (1) comprises three or more wheels (7, 7', 13), it being possible to rotate the front wheel (13) with respect to the steering column (18). In this case, a sensor (24) determines the angle of rotation between the front wheel (13) and the steering column (18) and, as a function of this angle of rotation, actuates the tilting means (9, 9') of the vehicle. As a result of the consequent tilting of the front frame pan (3) and as a consequence of the speed at which the vehicle (1) is travelling, the front wheel (13) and the tilting angle will automatically adopt the correct level for allowing the vehicle (1) to travel through the bend in a stable manner at the given speed. Controlling the tilt via the difference in angular rotation between the steering column (18), which is flexibly connected to the front wheel (13), and the front wheel (13), it is possible to control the tilt in a simple and robust manner.

IPC: G11B19/04
Filed: 2000-04-11
Abstract: In the disc controlling system, a buffer memory stores sector by sector data read from a disc or data to be written to the disc. A memory controller allows a floppy disc drive to intermittently read sector by sector data from the disc for supply to the buffer memory or intermittently write sector by sector to the disc data supplied from the buffer memory. When the floppy disc drive is not writing data to or reading data from the disc, data read from the disc is supplied sector by sector from the buffer memory to the system bus or data to be written to the disc is supplied sector by sector to the buffer memory from the system bus.

Title: Rotary belt tensioner with hydraulic damping
Inventor: MUSSELMAN DARYL D
IPC: F16F9/14
Filed: 1998-11-20
Abstract: A belt tensioner for use in an engine comprises a fixed structure attached to the engine and a moveable structure biased in a belt tensioning direction. One of the fixed and movable structures defines a fluid chamber containing an incompressible fluid, while the other of the two structures defines a chamber dividing structure within said fluid chamber. The fluid dividing structure defines two chamber portions and is constructed such that relative movement of the moveable structure displaces fluid from one chamber portion to the other. The chamber dividing structure is also configured so as to allow the fluid to flow between chamber portions in a restricted manner so as to yieldingly resist the relative movement of the moveable structure, whereby the fluid flow restriction is greater when the moveable structure moves in the opposite direction than when the moveable structure moves in the belt tensioning direction.

Title: State copying method for software update
Inventor: KLING LARS-ORJAN
IPC: G06F8/656
Filed: 1999-03-11
Abstract: To provide an approach to software update with scaleable disturbance there is proposed a state copying method for a computation system with at least two logic partitions wherein a state of new software in a standby partition (6, 16) is updated to the state of old software in an executing partition (16, 6) while continuing execution of the old software. Data is transferred from the executing partition to the standby partition in a scaleable way and as soon as the same state is achieved for the standby partition (6, 16) and the executing partition (16, 6) the execution is switched to the new software. This allows to scale the degree of disturbance due to the software update to what is deemed suitable.
