Patent CA-2304356-C (CA)
Inventor: SHIMOMURA MASARU
IPC: H02P9/14
Filed: 2000-04-06
Granted: 2002-12-03
Abstract: An excitation controller sets an output terminal reference voltage of a synchronous machine from a reactive current output from the synchronous machine and a high side reference voltage of a transformer, and controls the field current to be supplied to the field winding of the synchronous machine in response to the deviation between the reference voltage and the output terminal voltage.      This makes it possible to solve a problem of a conventional excitation controller in that although it can maintain the transmission voltage on the transmission bus at a fixed value, an expensive PD is needed for detecting the transmission voltage on the transmission bus, which increases the manufacturing cost of the excitation controller.

Patent CA-2308651-C (CA)
Title: A method of controlling base station transmitting power during soft handoff
Inventor: HASHEM BASSAM
IPC: H04B7/005
Filed: 2000-05-17
Granted: 2010-04-27
Abstract: A mobile station in a CDMA cellular radio system transmits a possibly unique power control command every power control group time when the mobile station is in contact with a single base station. When the mobile station is in soft handoff (in communication with two or more base stations simultaneously), however, the mobile station sends the same power control command for several power control group times, thus reducing the probability of receiving an erroneous power control command at a base station. The base stations synchronize their power levels periodically according to a predetermined number of power control command groups, resulting in more optimum base station power transmission levels, in turn resulting in a reduction in system noise and an increase in system capacity.

Title: Flexible radio access and resource allocation in a universal mobile telephone system (umts)
Inventor: WIDEGREN INA
IPC: H04W28/18
Filed: 1999-04-01
Granted: 2010-03-16
Abstract: The present invention provides flexible radio access and resource allocation in a Universal Mobile Telephone System (UMTS). A UMTS Terrestrial access network (UTRAN), in response to a radio access bearer service request, allocates resources necessary to support a communication with a mobile radio. The UTRAN includes plural base stations for communicating with mobile radios over a radio/air interface using radio channel resources allocated by a radio network controller connected to the base stations. External network service nodes interfacing with external networks communicate with the UTRAN  over a radio access network interface. The UTRAN provides a radio access bearer service to the external network service nodes, and radio access bearers are dynamically assigned to radio channel resources by the UTRAN. When establishing each bearer, the UTRAN    flexibly maps the radio access bearer to physical transport resources through the UTRAN  and radio channel resources over the radio/air interface.

Abstract: A plow assembly for vehicles such as pickup trucks and tractors for moving snow or other materials, as well as for bulldozers, graders and the like for excavating and grading dirt, sand, gravel or other plowable materials, has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the rear of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. At least one actuator, such as an hydraulic fluid power cylinder, is connected to the plow wing to move the wing between the retracted, extended and forwardly angled positions. In a preferred embodiment, an extendable plow wing is included on each end of the main plow with at least one actuator connected to each of the respective plow wings. Optionally, each plow wing may be movable via a pair of actuators, whereby the actuators in each respective pair are operable independently of one another to move the plow wings independently between their respective retracted, extended and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U-shape which facilitates pushing snow, dirt, sand or other plowable material without the material slipping off the plow blade ends. The main plow may include a section formed from polymeric sheet material for weight reduction. Because the plow wings are movable along the rear surface of the plow, the front surface of the plow provides a substantially continuous, uninterrupted surface for moving the plowed material therealong.

Title: Fuel injector with an improved poppet which is increasingly conformable to a valve seat in response to use
Inventor: ANDERSON KEVIN R
IPC: F02M61/08
Filed: 2002-01-08
Granted: 2007-05-22
Abstract: Poppets for fuel injectors are provided with an improved sealing surface by making the poppet from a softer material than is known in the prior art. Instead of providing a Rockwell C hardness value of 50 or greater, as is known to those skilled in the art of poppet manufacture, the improved poppet is made of a softer material that allows the valve head of the poppet to wear in such a way that its shape conforms more accurately with a valve seat of the nozzle of a fuel injector. This also provides the beneficial result of improved salt water corrosion resistance. By using a softer metal to make the poppet, the improved sealing characteristic improves fuel efficiency of the engine and reduces emissions of undesirable compounds.
