Patent CA-2326112-A1 (CA)
Inventor: SKAARUP ERIK
IPC: F03B13/14
Filed: 1999-03-23
Abstract: A method for impelling water in e.g. a lake (2) by with a pump (1) transforming the waves of the lake into whirling water (14) which is sent down towards the bottom (4) of the water area. The pump comprises a horizontally extending whirl pipe (7) with a longitudinal slot (8) and at least one preferably curvedly extending baffle (9) with a top front edge (10a) mainly facing a wave front in the lake in operation and a bottom rear edge (10b) extending along the slot. Both ends of the whirl pipe are fluid-connected to a submersible pipe (16) extending down towards the bottom of the water area. The pump is simple and reliable as it functions without movable parts. The pump can without costs for external energy take surface water high in oxygen and atmospheric air down to enrich "dead" bottom water low in oxygen. At the same time the pump can advantageously be used for removing undesired constituents such as superfluous biomass from the lake and add desired additives such as lime to this.

Patent CA-2333810-A1 (CA)
Inventor: LEHMANN STEVEN M
IPC: H04N9/64
Filed: 2001-02-01
Abstract: A mobile storage unit includes a drive system which is operable in response to rotation of an actuator handle mounted to the mobile storage unit.  A torque limiting mechanism is interposed between the actuator handle and the drive system, for rotating an input member of the drive system in response to rotation of the actuator handle. The torque limiting mechanism is operable to de-couple the actuator handle from the drive system input member when an excessive force is applied to the actuator handle, to prevent adverse effects which can result from application of an excessive force to the components of the drive system. The torque limiting mechanism includes a hub mounted to the actuator handle and an input member mounted to an input shaft associated with the mobile storage unit drive system. One or more engagement members are interposed between the hub and the input member, and are biased toward an engaged position in which the engagement members couple the hub and the input member together so as to transfer rotary force from the actuator handle to the input shaft. When a force exceeding a predetermined threshold is applied to the actuator handle, the engagement members move to a disengaged position to de-couple the hub member from the input member, and to thereby prevent transfer of such force to the input shaft. The engagement members are preferably in the form of spherical members which are received within passages formed in the hub member and are seated in passages or recesses formed in the input member. A spring bears between each engagement member and a set screw engaged with the hub member, and the biasing force exerted by the spring can be adjusted by movement of the set screw so as to adjust the threshold force required to move the engagement members to the disengaged position.

Title: Polarization and wavelength stable superfluorescent sources
Inventor: FALQUIER DARIO G
IPC: G01C19/72
Filed: 1999-10-29
Abstract: The instability of the mean wavelength of a superfluorescent fiber source (SFS) is reduced by randomizing the polarization of light from a pump source or by using polarization maintaining components. In one embodiment, the polarization of a pump source is made more random, leading to greater stability of the mean wavelength of the SFS, with an output mean wavelength that is stable to better than 3 ppm for full rotation of the pump polarization state. In another embodiment, the polarization of optical radiation throughout the device is kept substantially constant by using polarization maintaining fiber and components, thereby leading to enhanced mean wavelength stability of the SFS.

Title: Method and apparatus for controlling a transmission power threshold of a satellite communication system
Inventor: WRIGHT DAVID A
IPC: H04B7/185
Filed: 2001-06-18
Abstract: A method and apparatus for closed-loop power threshold leveling for a satellite communication system. An aspect of the present invention includes a plurality of user earth terminals (UET), a satellite and a network control center (NCC). The NCC  polls the UETs to obtain power profile information from the UETs. When polled, the UETs form power profile responses, and send the responses back to the NCC: The NCC forms a power profile database and statistically analyzes the power profile information to determine an uplink power threshold adjustment. The NCC  transmits the uplink power threshold adjustment to the satellite which adjusts an on-board uplink power level threshold in response to the uplink power threshold adjustment. In systems using multiple coding levels, the NCC determines uplink power offset values corresponding to the individual coding levels. The NCC delivers the uplink power offset values to the UETs which update their local power offset values stored in memory.
