Title: Fast protection switching by snooping on upstream signals in an optical network
Inventor: KIM KYEONG-SOO
IPC: H04B10/00
Filed: 2002-01-17
Abstract: An optical network has an optical splitter connected to (1) a working optical subscriber unit (OSU) of a working circuit via a working optical fiber, (2) a protection OSU of a protection circuit via a protection optical fiber, and (3) one or more optical network terminals (ONTs). The present invention enables fast protection switching from the working OSU to the protection OSU. In one embodiment, the arrival times of corresponding upstream ranging reply PLOAM cells are measured at both the working and protection OSUs during ranging operations of the working OSU. In another embodiment, a cell delineation procedure is initiated at the protection OSU during normal, non-ranging operations of the working OSU to enable the protection OSU to correctly delineate upstream cells and the arrival times of corresponding upstream cells are then measured at both the working and protection OSUs. In either case, a propagation delay value is generated based on the measured arrival times for use by the protection OSU  for communications with the one or more ONTs if and when protection switching is implemented upon detection of a failure in the working circuit, possibly without requiring the protection OSU to perform any ranging for the one or more ONTs.

Title: Olfactory ensheathing cells isolated from the lamina propria
Inventor: MACKAY-SIM ALAN
IPC: A61F2/44
Filed: 2000-10-27
Abstract: A method is described for isolating ensheathing cells, in particular those from olfactory lamina propria and use of the isolated ensheathing cells and lamina propria respectively in transplantation. Isolated lamina propria and ensheathing cells from the olfactory mucosa are well suited for autologous transplantation, where the donor and recipient are the same, as surgical biopsy of the olfactory mucosa is less damaging than isolating tissue from other location of a person's body, for example the olfactory bulb.  Transplantation is particularly directed to neural regions (for example the brain, spinal cord and/or peripheral nerves) of a human to assist recovery of acute and chronic nerve damage following surgery or trauma.

IPC: F16H59/02
Filed: 2001-09-19
Abstract: Because a shift lever device 10 uses attracting force of a fixed iron core 150A, 216A of a magnet 150 or an electromagnet 216 in switching between a lock state and an unlock state at a shift lock mechanism 118 and a key interlock mechanism 200, the mechanisms can be made compact. When a shift lever 12 is changed from a "D" shift position to a "4" shift position and when the shift lever 12 is changed from a "2" shift position to an "L" shift position, a link 30 is rotated in a same direction. Thus, a sliding direction of a slider 38 which detects a rotational position of the link 30 is only one, and a placement size of a detecting member 48 can be made small and the device can be made compact. Because the shift lock unit 88 is equipped integrally with shift lock mechanism 118, and the link 30, the slider 38 and the detecting member 48 of a sensing mechanism, the shift lock unit 88 can be made compact.

Patent CA-2405699-A1 (CA)
Title: Boom mechanism
Inventor: BEAN ANDREW J
IPC: B66F11/04
Filed: 2001-03-20
Abstract: A boom mechanism that is cooperable with a lift vehicle or base structure (108) includes a tower boom (12) and an upper boom (20) liftable in a dependent relationship by a single lifting mechanism (28). The tower boom and the upper boom are respectively pivotally secured to an upright (16) having a fixed orientation by a tower link (34) or the like. A timing link (26) is secured between the tower boom and the upper boom, and a lifting mechanism is secured between the upright and the upper boom. As the upper boom is driven by the lifting mechanism, the timing link secured to the tower boom causes the tower boom to pivot about a tower boom nose pivot (18), thereby raising both the upper boom and the tower boom in a dependent relationship. The construction helps to minimize the need for tail and frame counterweight (112) by controlling a position of the platform (24) in configurations of both forward and rearward instability. As a consequence, the gross vehicle weight can be considerably reduced.

Abstract: A brake cover (18) and shaft (24) rotate with a pedal lever (20) relative to a central section (14) of the housing (12) rotate a pedal gear (76). The pedal gear (76) rotates a sensor gear (74) to rotate a sensor arm (46) about a sensor axis (48). The sensor arm (46) supports sensor members (58) that move along sensor bands (50) to generate an electrical signal. As the brake cover (18) rotates with the pedal lever (20) it uncoils coil springs (84) to cause brake shoes (80) to pivot radially outward about respective posts (82) frictionally engage the interior surface (78) of the central section (14) to thereby provide a resistance or hysteresis to movement of the pedal lever (20). One feature resides in at least two elements (74,76) to interconnect the sensor arm (46) and the pedal arm (20) to reduce space while maintaining the requisite movement of the sensor members (58) over the sensor bands (50) and the other feature resides in spacing the braking mechanism axially from the sensor arm (46) in radially overlapping relationship to one another along the pedal axis (A).
