Title: A-base revenue meter with power quality features
Inventor: GUNN COLIN N
IPC: G01R21/133
Filed: 2000-02-18
Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power.
Patent CA-2301774-A1 (CA)
Inventor: CHIN SEO-YONG
IPC: G10L15/06
Filed: 1998-08-25
Abstract: L'invention concerne un procédé servant à gérer l'enregistrement de signaux vocaux d'entrée dans un appareil de reconnaissance vocale, utile pour un combiné et pour un dispositif mains libres. Dans le procédé, on détermine si le combiné est mis en mode mains libres lorsque le combiné est installé sur un support, ce qui permet une connexion avec le dispositif mains libres. Si le combiné est mis en mode mains libres, un signal vocal d'entrée enregistré du combiné est comparé à signal vocal d'entrée enregistré du poste mains libres, pour permettre de calculer une différence de signaux d'entrée entre ceux-ci. Un procédé de reconnaissance vocale est mis en oeuvre si la valeur de différence entre les entrées est une valeur minimum, c.-à-d. sensiblement égale à zéro. Si la différence entre les entrées est supérieure à la valeur minimum, un signal vocal d'entrée est alors enregistré pour le poste mains libres en réponse à une confirmation de l'utilisateur. Si la différence entre les entrées est inférieure à la valeur minimum, le signal d'entrée vocal est enregistré pour le combiné en réponse à une confirmation de l'utilisateur.

Title: Heavy-duty laser plate cutting machine
Inventor: SCOTT WILLIAM B
IPC: B23K26/04
Filed: 2000-09-07
Abstract: A method and apparatus for real time control of laser beam characteristics in a high power laser-equipped machine tool. A beam path input signal is produced related to changes in the length of the laser beam path as the processing head of the machine tool moves over the workpiece. An integrator produces a signal related to the real time changes in thermal loading of the laser output coupler as the laser beam is applied and as the output power level is adjusted. The beam path and thermal loading signals are used to drive a collimator so as to correct in real time for altered beam characteristics introduced by path length changes and thermal lensing of the output coupler. The result is to maintain control of the beam size at the focus optic. In addition, a further integrator produces a signal related to the real time changes in thermal loading of the focal optic as the laser beam is applied and as the input laser power level is adjusted. This correction signal is applied to the focus optic adjustment mechanism to correct in real time for any shift in the focus optic caused by thermal lensing of that optic.

Title: Prop rotor hub
Inventor: BROEKHUIZEN WILLEM
IPC: B64C27/48
Filed: 2000-09-26
Abstract: A prop rotor hub includes a constant velocity joint in the same plane as a prop blade yoke. Torque is transmitted from a shaft to the blades through the CV joint, hub plates attached to the CV joint, and the yoke, which is attached to the hub plates. Providing all elements in a substantially planar arrangement results in a hub assembly which has significantly less height than a traditional design. The hub itself is in-plane with the yoke, resulting in a more efficient torque transmission from the mast to the rotor.

Title: Methods for error proofing
Inventor: DYER TERRENCE O
IPC: G05B19/418
Filed: 2000-09-28
Abstract: Methods for error proofing (20), which also improve material, or information, flow through a process, are described. In one embodiment, the method includes the steps of identifying a process responsible for at least one error, process mapping (14) the identified process, identifying (16) at least one step in the identified process at which scrap and/or nonconformance occurred, and razing (18) the identified process. The step of razing, in the one embodiment, is performed by determining whether a plurality of errors throughout the identified process occurs, and if a plurality of errors are identified throughout the identified process, determining whether a different process can be substituted for the identified process, and if the different process can be substituted for the identified process, then substituting the different process for the identified process. If the different process cannot be substituted for the identified process, then the process further includes performing the steps of determining whether the identified step (52-70) can be eliminated, and if the step can be eliminated, then eliminating the step. If the step cannot be eliminated, then the process further includes performing the steps of determining whether the identified step can be simplified, and if the step can be simplified, then simplifying the step. After razing the process, the razed process is error proofed, and then the error proofed razed process is analyzed to verify that scrap and nonconformance has been reduced.

Patent CA-2323294-A1 (CA)
Title: Motor base for vibratory apparatus
Inventor: MUSSCHOOT PAUL
IPC: H02K7/075
Filed: 2000-10-13
Abstract: A motor base for use in vibratory apparatus. The vibratory apparatus includes at least one eccentric drive having a driven shaft rotatably mounted on a moveable exciter. A motor is provided having a motor shaft which is spaced from the eccentric drive and coupled to the eccentric drive by a drive belt. Rotation of the motor is transferred by the drive belt to the eccentric drive, which generates a vibrational force. The vibrational force moves the exciter in various directions during operation of the vibratory apparatus. The motor base comprises a rigid support, such as an arm, having a free end adapted to carry the motor. The arm is supported to move about an axis of the driven shaft, so that the arm maintains a center distance between the motor shaft and the driven shaft. A resilient support, such as a compression spring, is attached to the free end of the arm, below the motor, to absorb any resulting forces acting on the arm from the movement of the exciter. The motor base maintains a center distance between the motor shaft and the driven shaft, thereby increasing drive belt life by minimizing tension variations in the drive belt.
