Patent CA-2600781-A1 (CA)
Inventor: BROWN KEVIN
IPC: H05H7/18
Filed: 2006-03-10
Abstract: A linear accelerator comprises a series of accelerating cavities, adjacent pairs of which are coupled via coupling cavities, in which at least one coupling cavity comprises a rotationally asymmetric element that is rotateable thereby to vary the coupling offered by that cavity. A control means for the accelerator is also provided, adapted to control operation of the accelerator and rotation of the asymmetric element, arranged to operate the accelerator in a pulsed manner and to rotate the asymmetric element between pulses to control the energy of successive pulses. A beneficial way of doing so is to rotate the asymmetric element continuously during operation of the linear accelerator.  Then, the control means need only adjust the phase of successive pulses so that during the brief period of the pulse, the asymmetric element is "seen" to be at the required position. The asymmetric element can disposed within an evacuated part of the accelerator and rotated by way of an electromagnetic interaction with parts outside the evacuated part. No parts associated with the drive need therefore pass through the vacuum seal. This could be achieved by providing at least one magnetically polarised member on the asymmetric element and at least one electrical coil outside the evacuated part.

Title: Vehicle with variable wheel camber
Inventor: GROSSMAN MATTHEW C
IPC: B62K5/05
Filed: 2006-03-04
Abstract: A tricycle convertible to a bicycle. The tricycle has a first wheel rotatably mounted on one end portion of a frame, and a pair of laterally spaced wheels rotatably mounted on a second end portion of the frame, wherein the laterally spaced wheels are movable, while the tricycle is in motion, between a first position with relatively wide ground-level spacing and a second position with minimal ground-level spacing. A wheel hub capable of providing adjustable wheel camber has left and right pivotally mounted axles extending laterally from the hub body, the axles each adapted to support a wheel and mounted so as to pivot vertically, and a dual camber control mechanism coupled to the axles and adapted to provide coordinated camber adjustment in the same direction for wheels on both axles. The hub has sufficient range of motion to allow the wheels to change from negative camber to positive camber, and is useful in a method of stabilizing a bicycle or the like to increase safety during rider training. The method involves a tricycle mode of operation in which the laterally spaced wheels have negative camber, and a bicycle mode of operation in which the laterally spaced wheels have positive camber, with a change from tricycle mode to bicycle mode while in motion, whereby a rider in training may start moving with stable three-point ground contact and, when in motion and balanced, effectively start riding a bicycle.

Filed: 2006-10-18
Abstract: Using Zero Make Ready Bed Die Cutting, the top surface of the Cutting Plate/Platen/counter of a Flat Bed Die Cutting Machine is etched or engraved by laser or other method, to create a "female" channel. The channel should be sufficiently deep and wide, to accommodate the male cutting blades of the Cutting Forme being used. Cutting blade contact with the base of the channel, whilst not desirable, may occur due to reasons of machine age and/or wear or Operator ability or preference. The fundamentals of Zero Make-Ready remain unaffected. The Cutting Plate/Platen can be of a single or multi layered composition and should be affixed and registered at the same time that the cutting Forme is loaded and located. Using centre lines, locating pins, or any other method of registering the two, the female channel must register with and accommodate, the male cutting blades to affect a clean cut of the required design of die cut blank or shape.

Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

Abstract: A device for imparting vibration to a body is disclosed, such as may be used for whole body vibration treatment. In one embodiment, a pair of linear motors are disposed on a base.  Each linear motor has a stator portion secured to the base and a moveable portion that linearly reciprocates with respect to the stator in response to a supplied current. A  current source is electrically coupled to the linear motors for supplying alternating current to the linear motors.  A controller is in communication with the current source for controlling movement of the linear motors at a selected phase relationship between the linear motors. A  platform is coupled to the moveable portions of both linear motors using rigid rubber supports.  The platform moves with respect to the base in response to movement of the linear motors.  In a level mode, the dual linear motors are operated in phase, such that the platform remains level. In a tilt mode, the linear motors operate out of phase, imparting a vibrating tilt to the platform. A  moveable mount, such as a rubber mount, couples the platform to the moveable portions of each linear motor to accommodate the tilt.
