Patent CA-2304151-A1 (CA)
Inventor: MORGAN ROBERT A
IPC: H01S5/20
Filed: 1997-10-23
Abstract: A Vertical-Cavity Surface Emitting Laser (VCSEL) for producing a filamented light ouput. In a preferred embodiment, this is accomplished by providing a number of discrete objects that are positioned adjacent to or within one or both of the cladding mirrors, or within the active region itself. The discrete objects may alter the reflectance, current injection and/or gain of the VCSEL at corresponding discrete locations, thereby causing the filamented light output. Besides providing a filamented output, the VCSEL of the present invention operates at a low drive current, provides high performance, and occupies less physical area than a broad-area (wide aperture) VCSEL. Thus, the VCSEL of the present invention has a number of advantages provided by a conventional laser including speed, efficiency and power, but does not suffer from many of the disadvantages of high coherence. The utilization of speckle averaging within multi-mode fiber interconnections and CD-like spatial imaging applications are contemplated.

Patent CA-2307811-A1 (CA)
Inventor: DUVE JEFF
IPC: H03B5/20
Filed: 2000-05-04
Abstract: A single operational amplifier voltage control oscillator circuit in which varying the voltage inputted at the positive node of the amplifier creates changes in output frequency. The circuit inputs a predetermined voltage through a series resistor into a first node of an amplifier and directs an output signal created by the amplifier back to the first node through a second series resistor. In addition, the output signal of the amplifier is also directed back to a second node of the amplifier through a resistor and capacitor time delay network. This causes the charge on the time delay capacitor to rise until the input level present at the two nodes is equal which causes the amplifier to deactivate and the capacitor to discharge until reaching a predetermined threshold which causes said amplifier to reactivate. This creates a frequency output.

IPC: G06F21/79
Filed: 1998-11-02
Abstract: The invention concerns a method for reducing occupancy of descriptors (41) used for protecting files (44) in storage; it consists in organising security by separating the functions (22-28) whereto the files (reading, writing, erasing...) are going to be subjected from the protection modes (19-21) to which said functions should subscribe to be executed on the files concerned. The descriptors then comprise a number of octets (47-49) equal to the number of protection modes proposed. The bits of these octets depending on whether they are active or inactive refer to function memory words (50) whose number is directly equal to the number of active bits in the mode memory words. The function memory words comprise references to secret codes (15) to be used for implementing the desired security functions.

Patent CA-2329710-A1 (CA)
Inventor: IRISH HERBERT A
IPC: B01F27/71
Filed: 1999-04-22
Abstract: A flow directing device (12), system and method for delivery and pumping medium to high consistency stock slurries eliminates bridging of stock, creates a non-vortexing improved flow into the pump suction of a pump (32), is independent from pump operation, minimizes "slip/stick", and does not mix air into the pulp fibers. The flow directing device (12) is a low-speed, mechanical device including a two-stage turbine, a turbine shaft, a turbine mounting adapter, a gear reducer and an electric motor. The device is used with a dropleg to assist flow of medium to high consistency suspensions (pulp) to the pump, preferably a rotary pump. The flow directing device (12) is operated independently from the pump (32). The flow directing device (12) and pump (32) work in concert with each other to form a stock pumping system capable of handling paper stock consistencies from 8-18 % without the problems associated with other types of pumping systems. This is achieved by first liberating liquid from the stock slurry by providing a localized shear stress to the stock slurry using the first turbine (16) and applying a shear stress to the liberated stock slurry in a sufficient amount to transition the stock slurry to a non-Neutonian, Bingham-plastic fluid using the second turbine (14). This substantially reduces the apparent viscosity of the stock slurry and improves pumping efficiency.

Inventor: LUDTKE HAROLD A
IPC: H04N21/436
Filed: 1999-04-29
Abstract: A media manager provides data flow management and other services for client applications on devices coupled together within a network. Preferably, these devices are coupled together within an IEEE 1394-1995 serial bus network. A device control module is generated for each available device for providing an abstraction for all of the capabilities and requirements of the device including the appropriate control protocol, physical connections and connection capabilities for the device. The media manager also manages the flow and format of data transfers between the devices on the network. Through an interface, a user accesses the media manager and enters functions which are to be completed using the devices coupled together on the network. If the appropriate devices are available, the media manager controls and manages the completion of the requested task. If the appropriate devices are not available, but the required subdevices are available in multiple devices, the media manager forms a virtual device from subdevices in multiple devices in order to complete the requested task. Once the appropriate devices and subdevices are assigned to a task, the media manager determines if the data to be transmitted needs to be converted from one format into another format.  If necessary, the media manager will also control the format conversion during the data transfer operation. The media manager also provides network enumeration and registry searching capabilities for client applications to find available services, physical devices and virtual devices.

Title: Rolling massage device continuous motion reciprocal drive structure
Inventor: WU DONG-HER
IPC: A61H23/02
Filed: 2001-01-23
Abstract: A rolling massage device continuous motion reciprocal drive structure comprised of a long drive shall, the two end of which arc pivotably installed in a base plate that is also inserted through the center section of a sleeve hole at the lower extent of a bottom mount, and a massage device sleeved over the center section of the drive shaft. The center section of the drive shaft consists of a clockwise spiral slide tracking groove and a counter-clockwise spiral slide tracking groove in a crisscross arrangement and, furthermore, completes a two-ended cycling crossed bi-directional screw rod. The upper extent of the center section area of the bottom mount sleeve hole provides for the implantation and sleeving in of a cylindrical active link block having a double hyphen- profiled guide plate extending from its lower end that is inserted into the slide tracking grooves.  As such, while the drive shaft is being rotationally driven in a set direction, since the guide plate in the groove is forced to follow in the direction defined by the interior section of the track path, the bottom mount equipped with massage components at its top surface is carried into continuous motion in an axial direction and, furthermore, achieves continuously driven reciprocal travel following the crisscross configuration of the clockwise slide tracking groove and the counter-clockwise slide tracking groove on the crossed bi-directional screw rod, which is among the innovative features of the present invention.

Abstract: A tool (10) is provided for use in submerged condition for installing anchor or foundation elements such as piles (12) in a ground formation that is submerged under a body of water. A hammer body is fixedly supported in axial alignment with the head of a pile that is to be driven and carries a reaction body guided for movement thereon in a direction that is axial to the pile. The hammer body and reaction body define opposed first and second ends of an expansion chamber. A pyrotechnic charge is initiated to create a rapidly expanding volume of high pressure gas in the expansion chamber to generate a downwards pressure force pulse to drive the pile, an equal and opposite upwards pressure force pulse being applied to the reaction body. Damping structure operatively associated with the reaction body interacts with the water in which the tool is submerged using the inertia of the water to resist upwards movement of reaction body.
