Title: System for filling and assembling pharmaceutical delivery devices
Inventor: REYNOLDS DAVID L
IPC: A61L2/07
Filed: 2002-11-22
Abstract: A system is provided which permits syringe barrels of prefilled disposable syringes to be filled and capped on standard vial filling equipment, and which permits the syringe body and piston comprising the barrel to be simultaneously sterilized by a sterilizing gas. The system provides means for stabilizing syringe barrels so they can be conveyed upright on their bases without tipping through vial filling and capping equipment. Preferably, the stabilizing means comprises a cylindrical sleeve into which the lower end of the syringe body is inserted, thereby stably supporting it against tipping. The system also provides means by which the piston is retained in close proximity to the lower end of the syringe body, but slightly separated therefrom to permit access to all surfaces of the piston by a sterilizing gas. Preferably, the piston is retained directly below the lower end of the syringe body, and substantially centred therewith, to permit the piston to be inserted into the lower end of the body merely by pushing the body and piston together.

Filed: 2005-05-03
Abstract: Mechanisms for providing requested date items in a request-driven enumeration session while retaining to control over how much inter-message context information is retained by the data provider. Upon receiving a request for the data items, the data provider identifies a portion of the data items to be provided in the first response along with context information that reflects that the first portion of information has been provided. The data provider then makes a determination of how much of the context is to be provided to the data receiver system, and then provides that appropriate context information to the data receiver. Furthermore, the data provider provides a response that includes the first portion of the data items. The data receiver includes this first provided context information in the second request for the next portion of the data items, allowing continuity in the data transfer session.

Abstract: A chiral in-fiber tunable polarizer implemented in a chiral fiber structure is provided. The chiral fiber is selected with a predetermined handedness and scatters (by reflecting, coupling into the fiber core or otherwise) the circularly polarized light matching its handedness while transmitting circularly polarized light of opposite handedness. By combining the chiral fiber with another fiber component having a non-cylindrical core, the inventive apparatus produces a linearly polarized wave with a predetermined orientation. The orientation may be adjusted by rotating the fiber component around its central axis. The chiral fiber structure may be configured as a long period chiral fiber grating. Optionally, the chiral fiber structure may be configured with a variable pitch along its length, such as a chirped fiber grating, an apodized fiber grating, or a set of multiple sequential chiral polarizer elements with different pitches. This variable pitch arragement results in output light having a configurable polarization spectrum of a predetermined shape.

Title: Quadrature modulator which employs four 90-degrees-shifted carriers
Inventor: BALLANTYNE GARY J
IPC: H03C1/54
Filed: 2004-03-17
Abstract: A quadra-polar modulator that is simple to implement and also provides good noise performance. The quadra-polar modulator includes four amplitude modulators and a combiner. Each amplitude modulator modulates a respective carrier signal with a respective input signal to provide a respective output signal. The combiner then combines the four output signals from the four amplitude modulators to provide a modulated signal. Each amplitude modulator may be implemented with a switching amplifier, such as a supply modulated class E amplifier. Two input signals are obtained by summing separately an inphase (I) modulating signal and an inverted I modulating signal with an offset value. The other two input signals are obtained by summing separately a quadrature (Q) modulating signal and an inverted Q modulating signal with the offset value. The offset value can be selected based on the expected magnitude of the modulating signals. The four carrier signals are in quadrature to each other.

Patent CA-2527929-A1 (CA)
Title: Synchronization of timing advance and deviation
Inventor: TERRY STEPHEN E
IPC: H04J3/06
Filed: 2001-04-05
Abstract: A system and method for reducing the latency from timing deviation (TD) measurement to time advance (TA) adjustment. The invention uses a deterministic procedure to coordinate time advance (TA) commands and timing deviation (TD) measurements so that failed transmissions or mobile terminals signal propagation changes can be recognized and corrected much more rapidly. Radio resource efficiency is maximized by minimizing signaling overhead through effectively reducing the frequency of time advance commands. This is accomplished by using TA command signals which include a Connect Frame Number (CFN) to specify particular radio frames for time advance (TA) adjustment. The potential for timing deviation (TD) measurements to be incorrectly processed in conjunction with adjusting a physical reception window and calculating mobile termination location is minimized, without excessive command signaling requirements.

Title: Split-cycle engine with dwell piston motion
Inventor: BRANYON DAVID P
IPC: F02B33/22

Abstract: An engine includes a crankshaft having a crank throw, the crankshaft rotating about a crankshaft axis. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of a four stroke cycle during a single rotation of the crankshaft. An expansion piston is slidably received within an expansion cylinder. A  connecting rod is pivotally connected to the expansion piston. A mechanical linkage rotationally connects the crank throw to the connecting rod about a connecting rod/crank throw axis such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of the four stroke cycle during the same rotation of the crankshaft. A path is established by the mechanical linkage which the connecting rod/crank throw axis travels around the crankshaft axis. The distance between the connecting rod/crank throw axis and crankshaft axis at any point in the path defines an effective crank throw radius. The path includes a first transition region from a first effective crank throw radius to a second effective crank throw radius through which the connecting rod/crank throw axis passes during at least a portion of a combustion event in the expansion cylinder.
