  • Patent number: 10385964
    Abstract: Embodiments provide systems and methods for determining a position of a gear shift lever of a vehicle. A ferromagnetic target object having selected characteristics influences a magnetic field generated by a back bias magnet. A magnetic field sensor includes magnetic field sensing elements disposed proximate to the target object. Each magnetic field sensing element generates an electronic signal in response to sensed magnetic fields. The gear shift lever moves among a plurality of gears of the vehicle. The magnetic field sensor selects a set of the magnetic field sensing elements to determine a magnetic field difference based on a difference of amplitudes between the electronic signals that is related to a current position of the gear shift lever. Characteristics of the target object enable the magnetic field sensor to detect the position of the gear shift lever. The characteristics include edges proximate to a perimeter of the target object.

  • Patent number: 10359447
    Abstract: Elongated flexible probes can be disposed in holes of upper and lower guide plates of a probe card assembly. Each probe can include one or more spring mechanisms that exert normal forces against sidewalls of holes in one of the guide plates. The normal forces can result in frictional forces against the sidewalls that are substantially parallel to the sidewalls. The frictional forces can reduce or impede movement parallel to the sidewalls of the probes in the holes.

  • Patent number: 10274400
    Abstract: Methods and systems are provided for sensing particulate matter by a particulate matter (PM) sensor positioned downstream of a diesel particulate filter in an exhaust system. In one example, a PM sensor assembly may include rows of flow guides separated from each other by a gap where each of the flow guide includes a positive and negative electrode formed on opposite side surfaces.

  • Patent number: 9998026
    Abstract: Techniques are disclosed for assessing the conditions of LEDs and power supplies of solid state lighting systems. The techniques can be used, for example, to measure the capacitance of an output capacitor C in a switch-mode power supply (SMPS), and to measure the condition of the LEDs being driven by that power supply. In some cases, this assessment can be implemented in a lighting controller that controls the lighting system, which may be configured to simultaneously determine C and the conditions of LEDs. In one example case, the techniques can be implemented, for instance, in a micro-controller operating the lighting system. A lighting system implementing the techniques can be periodically assessed so as to provide real-time diagnostic capability. Numerous example embodiments of SMPS LED lighting systems will be apparent in light of this disclosure.
