Abstract: A method suitable for characterizing a motor, for instance a permanent magnet synchronous motor, includes obtaining a plurality of winding flux linkage values or terminal voltages of the motor, each corresponding to a different combination of phase current magnitude and phase advance. The resultant flux-linkage values or terminal voltages are transformed into the rotor dq reference frame. The flux linkage model is fitted to the one or more dq-axis flux-linkage values or terminal voltages and their linked phase current magnitude and phase advance using a process of parametric optimisation.

Abstract: A friction pad carrier for a vehicle disc brake includes a frame having an aperture through which a portion of a rotor rotating about a rotational axis extends. The frame mounts friction pads on opposite sides of the rotor. The frame includes lugs proximate each end that receive fasteners coupling the frame to an anchor plate mounted on an axle of the vehicle. The fasteners permit some amount of surge movement and sway movement between the frame and the anchor plate in a plane at the interface between the frame and the anchor plate and yaw movement about an axis perpendicular to the plane. A first alignment pin between one of the lugs and the anchor plate inhibits the amount of surge movement and sway movement and a second alignment pin between one of the lugs and the anchor plate inhibits the amount of yaw movement.

Abstract: A method of controlling a motor, for example of an electric power steering system, includes receiving a motor torque demand signal indicative of a torque required from the motor. A current demand signal indicative of the currents to be applied to each phase to meet the torque demand is generated from the motor torque demand signal. One or more operational values from the motor are determined. The current demand signal is set as a function of one or more parameters of the motor obtained by fitting a flux linkage model to the measured operational values. A motor circuit having the permanent magnet electric motor includes a control stage arranged to generate the current demand signal in response to a torque demanded of the motor. A modifying means modifies the magnitude and/or the phase of the current demanded for each phase of the motor by the controller.

Abstract: The present invention describes a method for determining in real time the level of activation of the trigeminovascular system. In particular, said invention can be applied in the field of medical devices capable of determining the activation index of the trigeminovascular system, mainly on the basis of the use of biomedical signals of hemodynamic character. The method establishes objective criteria for determining the degree of activation and is described as the result of the application of modelling and data fusion techniques. The method is also based on another type of signals, such as ambient signals, in order to improve statistically in real time the degree of activation determined.

Abstract: Device for measuring temperature and leakage current in a chip, which provides an output which linearly varies with the temperature. The device comprises a leakage inverter and an electronic module which digitalizes and linearizes the non-linear output of the leakage inverter. When providing a linear response, the need for storage and data interconnection is reduced, besides the numeric representation thereof is facilitated. The device can be used to measure temperature variations inside a chip and also to measure leakage current variations, which also entails measuring static power variations inside a chip.

Abstract: An fire-fighting system for arresting a fire in a flammable or combustible liquid storage vessel comprising a portable discharging apparatus and a portable installation apparatus. The portable discharging apparatus receives a fire-fighting agent from a supply hose and applies the fire-fighting agent to arrest a fire in a storage vessel. The portable discharging apparatus can be attached to a distal end of the portable installation apparatus so that the portable discharging apparatus can be mounted on a storage vessel. Furthermore, a plurality of portable discharging apparatuses can be mounted on a single storage vessel, using the same portable installation apparatus, to provide a large amount or a variety of fire-fighting agents or to provide fire-fighting agents at a specific location on the storage vessel. The portable installation apparatus can be extended to a variety of lengths so that it can mount a portable discharging apparatus on a variety differently sized storage vessels.

Abstract: A fax interface unit provides a novel way of sending and receiving a fax over a global computer network such as the internet. The fax interface unit is coupled to a legacy fax machine on one side and to both a local area network and the telephone network on the other side. When a first location transmits a fax document to a second location having an email address capable of receiving the fax document, the telephone network is bypassed and the transmitted fax document arrives as email at the second location, thereby reducing telephone cost and providing the second location with an archived document.
