Abstract: An apparatus and methods for determining the position of an elongate structure. A number of magnetic field sensors arranged at fixed spacing, each sensor being arranged to sense a magnetic field of a remote structure induced by the Earth's magnetic field in at least two orthogonal directions. In use, the magnetic field sensors are arranged remotely of an elongate structure having a longitudinal axis, such that the magnetic field sensors are spaced in a lateral direction relative to said longitudinal axis. An angular spacing for the magnetic field sensors about the longitudinal axis is determined according to the magnetic field readings in the two orthogonal directions and a distance between one or more of said magnetic field sensors and said elongate structure is determined based on said angular spacing determination.

Abstract: The disclosure provides simple, low-cost but accurate systems and related methods for on-die temperature sensing typically using calibration and without the need for precision voltage references. In some implementations, the system utilizes two user selectable temperature sensing elements and two user selectable DACs to provide a digital code for the sensed temperature. In some implementations, the two sensing elements can be used to calibrate against each other. For example, calibration can be useful to account for silicon local/global variation. Typically, one of the temperature sensors is diode-based, while the other is resistor-based. However, those of skill in the art will recognize that, in accordance with the disclosure, more than two sensors can be provided that can be calibrated against one another.

Abstract: In an alternator for a vehicle having field coils for generating rotating magnetic field and stator coils for generating alternating current voltages in response to the rotating magnetic field, each of three stator coils are wound on only one of three stator teeth provided equi-angularly in a two pole-pitch of the rotor so that coil ends of the stator coils exposed outside the stator teeth do not cross each other. Thus, all the coil ends are cooled equally by the cooling air and a temperature rise of the stator coils is minimized. In order to reduce magnetic noise the stator coils are grouped. The first group of coils are provided in contact with a stator core and a second group of coils. The first and second group of coils are shifted from each other by .pi./3 radian in electrical angle.

Abstract: An improved rotor end winding assembly for an electrodynamic apparatus includes a stack of conductive straps that are configured to turn about an end turn portion of a rotor and include a top strap, a bottom strap and a number of intermediate straps that are stacked between the top strap and the bottom strap. A space defined between the rotor shaft and the bottom strap is divided into a high pressure zone and a low pressure zone by a zone block. A stepped coolant passage defined in the stack includes an ascending passage that leads from the high pressure zone toward the top strap and in the direction of the zone block and low pressure zone, and a descending passage that leads from the ascending passage to the low pressure zone. As a result, coolant will flow from the high pressure zone to said low pressure zone to efficiently cool said stack of straps.

Abstract: Methods and apparatus to reduce wear on surfaces in sliding contact by inducing vibratory movement in one or more of the surfaces. The movement is substantially perpendicular to a plane of contact between the surfaces and substantially nonuniform across the area of contact. The nonuniform vibratory motion of one surface with respect to another results in small rotational vibration of one surface with respect to another even as contact is maintained between the surfaces. Rotational motions tend to decrease surface wear due to thermal mounding by moving the zone of actual contact with time; rotational motions also open temporary gaps between the surfaces which allow the escape of wear particles, thus decreasing subsequent abrasive wear. The invention may be applied to sliding electrical contacts, either linear or rotating, and to sliding frictional contacts, as in brakes and clutches.
