Title: Boost converter with reduced switching loss
Inventor: SYMONDS NEIL S
IPC: H02M3/156
Filed: 1999-12-17
Granted: 2004-04-13
Abstract: A low power loss boost converter (10) of the discontinuous conduction type includes an inductor (18) coupled between the boost converter (10) input and a junction, a current rectifier (20) coupled between the junction and the converter output, a switch (30) coupled between the junction and common, and a switch capacitor (46) coupled in parallel with the switch (30), the inductor (18) and an energy storage capacitance (40) associated with the input. The switch (30) is alternately opened and closed in switching cycles which alternately energize the inductor (18) and transfer the energy to the output load.      Power losses are reduced by providing switch closure at a near zero voltage and current switch conditions produced by a circuit resonance. The capacitor (46) reduces voltage across the switch during the switch open transient condition.
Patent CA-2360469-C (CA)

IPC: A01B69/08

Granted: 2005-07-19
Abstract: A wagon for agricultural use having an all-wheel steering mechanism. The wheels are hingedly attached to their respective axles. Steering alignment of the front wheels is provided by the wagon tongue, which is pivotally connected to the wagon frame and at least one of the front wheels. The front wheels are connected to each other by a steering linkage, consisting of two equal length members pinned to each other at a connection point. A front shaft crank is pivotally attached at the same connection point and rigidly attached to a rotatable shaft mounted with bearings to the underside of the wagon frame. Changes to the steering alignment of the front wheels causes lateral movement of the connection point, leading to rotation of the shaft and a corresponding direct change in alignment of the rear wheels, which are equipped with a similar system of linkages and cranks. This causes the front and rear wheels to follow the same path. Mounting the shaft above the axles increases ground clearance and mitigates the potential for damage to the steering mechanism. One of the axles may be pivotally attached to the wagon frame using a horizontal pin at substantially its midpoint, allowing angular pivoting of the axle in response to uneven terrain. The degree of pivoting is limited by stops integrally formed into the frame. The pivoting axle improves stability of the wagon, especially while turning and when transporting a top-heavy load.

Title: A low thermal stress case connect link for a straight tube coriolis flowmeter
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 2000-02-02
Granted: 2005-01-04
Abstract: Case connect links of a straight tube Coriolis flowmeter couple a balance bar/flow tube junction to the flowmeter case. Each case connect link has at least one out of plane bend in its surface to allow the case connect link to expand/contract in response to temperature differentials between the internal elements of the flowmeter. The expansion/contraction permitted by the out of plane bend prevents structural damage to the case connect link as well as to the flowmeter elements to whic h it is connected.

Abstract: The invention relates to a method for connection establishment and a radio system relaying packet traffic, in which system a terminal (402) is arranged to inform (700) the system network part (400) that it wishes to transmit data to the network part; the network part (400) is arranged to receive the message and to allocate a default amount of radio resources to the terminal; the network part (400) is arranged to inform (702) the allocated resources to the terminal; the terminal (402) is arranged to send a first control message (710) to inform the terminal's radio path characteristics to the network part. According to the solution of the invention, when the network part (400) allocates the default amount of radio resources to the terminal (402), the network part is arranged to reserve one or more radio blocks for the terminal's control messages. When the terminal (402) sends the network part information about its radio path characteristics, the terminal is arranged to inform in the message if there are additional characteristics. In that case, the terminal sends a second control message (712) comprising information about its radio path characteristics.

Abstract: Il est possible de corriger la presbytie et autres troubles associés de la vue en implantant dans une série de poches allongées formées dans le tissu de la sclérotique de l'oeil normalement à un méridien de l'oeil, une prothèse à base allongée présentant une surface dirigée vers l'intérieur reposant sur la paroi dirigée vers l'intérieur de la poche et présentant une crête sur la surface dirigée vers l'intérieur de la base s'étendant le long d'au moins une partie principale de la dimension principale de la base. L'effet combiné de la prothèse implantée est d'exercer une traction radiale dirigée vers l'extérieur sur la sclérotique dans la zone recouvrant le corps ciliaire qui prolonge la sclérotique dans la zone affectée ainsi que le corps ciliaire sous-jacent. Cette extension du corps ciliaire rétablit la distance de travail efficace de l'oeil presbyte en accroissant l'amplitude de l'accommodation. On a donc ainsi une prothèse sclérale améliorée pour le traitement de la presbytie et d'autres troubles de la vue dont un exemple type, conçu pour être en contact avec la sclérotique du globe oculaire, comporte un corps présentant une première et une deuxième extrémité, ainsi que (i) une forme plane, qui prolongeant la partie de la sclérotique en contact, accroît la distance de travail efficace du muscle ciliaire du globe oculaire, et (ii) un moyen stabilisant la prothèse à l'intérieur de la poche formée chirurgicalement dans la sclérotique du globe oculaire.

Title: Method and apparatus for detecting and suppressing a parallel arc fault
Inventor: PAHL BIRGER
IPC: H02H1/00
Filed: 2002-09-25
Granted: 2012-05-15
Abstract: Electrical equipment is safeguarded from damage due to parallel arc faults by a circuit that provides several levels of protection. A semiconductor switch and a current sensor are placed in series with the electrical equipment. When the current to the equipment exceeds a first threshold for a predefined period of time, the semiconductor switch is rendered non-conductive until the circuit is specifically reset. When the current to the equipment exceeds a greater second threshold, a pulsed signal alternately places the semiconductor switch in conductive and non- conductive states so that the average current applied to the equipment is within an acceptable level. The pulses are measured to determine whether a parallel arc fault has occurred. When the measured pulses are within a predetermined range, a parallel arc fault is declared and the semiconductor switch is rendered non-conductive. Should the current exceed an even greater third threshold, the semiconductor switch is immediately rendered non-conductive until the circuit is manually reset.
