    Abstract: In one embodiment, an apparatus includes a first magnetometer that measures a magnetic field. The apparatus includes a second magnetometer that measures the magnetic field. The first and second magnetometer are positioned a predetermined distance apart from each other in a direction. The apparatus includes computer-readable media embodying logic that access a first measurement of the magnetic field by the first magnetometer at a first time and a second measurement of the magnetic field by the second magnetometer at a second time. The logic compares the first measurement with the second measurement and, based at least in part on the comparison, determines that the first measurement approximately coincides with the second measurement. Based at least in part on the coincidence, the logic determines that a device comprising the apparatus has traversed the predetermined distance in the direction that they are positioned apart from each other.

    Abstract: Improved bearing roller elements are disclosed. A first disclosed improvement is the addition of vanes to a ring-roller type element which allows fluids (such as liquids or gases) to flow through the bearing assembly. The fluids can then provide convection cooling. With proper configuration, the use of such vaned ring-roller elements can even allow the creation of a pump, either as part of the larger apparatus' cooling system or as a dedicated device. A second disclosed improvement, which can be used in combination with the first or in isolation, is the use of magnetic spokes in ring-roller type elements which allows them to be driven by an electromagnetic field. The use of such magnetic elements in the bearing roller elements also allows electromagnetic braking and/or regenerative braking.A bearing assembly incorporating the roller elements in a ring configuration and using pre-load to produce additional benefits is also disclosed.

    Abstract: An automotive component assembly comprises an input circuit portion for a sensor and a component portion. The input circuit portion is aligned with the component portion in a desired assembly position. A pocket is at least partially defined by the component portion to receive the input circuit portion and a clamping force retains the input circuit portion between a first layer and a second layer of the component portion forming the pocket. An overmold material is applied to retain the input circuit portion and the component portion to one another.

    Abstract: Disclosed herein are example methods, systems, and devices involving electrically-conductive wires, such as standard IC bonding wires, that are configured so as to operate as inertial sensors. One embodiment of the disclosed methods, systems, and devices may take the form of a system that includes a first electrically-conductive wire and a second electrically-conductive wire, where the first wire and the second wire are electromagnetically coupled; and a sensor oscillator, where the sensor oscillator is coupled to the first wire and the second wire, and where the sensor oscillator is configured to output a sensor-oscillator signal that is frequency modulated based on a change in complex impedance between the first wire and the second wire, where the change in complex impedance is due to a displacement of the first wire relative to the second wire.

    Abstract: Of a counter apparatus, a first microcomputer and a second microcomputer communicate with each other and receive a crank signal with pulses. The first microcomputer detects a first pulse count number at a detection time point and transmits it to the second microcomputer. The second microcomputer detects a second pulse count number at a determination time point, which is an allowable delay time period later from the detection time point. The allowable delay time period is expected to elapse from the detection time point to when the first pulse count number is received by the second microcomputer. The second pulse count number is compared with a determination value, which is the sum of (i) the first pulse count number and (ii) the largest integer not greater than the quotient of T2/T1, T1 being a pulse period of the crank signal, T2 being the allowable delay time period.

    Abstract: A method of determining a speed of a wheel that involves providing a resolver having a rotor and a stator which resolver produces at least one output signal, operatively connecting the rotor to a wheel such that the resolver is rotated by the rotation of the wheel, producing digital signals indicative of a position of the rotor relative to the stator based on the at least one output signal, and calculating a velocity of the wheel from the digital signals. The digital signals may be used alone or in conjunction with analog wheel speed signals. Also a speed sensor for practicing this method.
