  • Patent number: 9593965
    Abstract: A non-contact adjustable hysteretic magnetic encoder includes a bipolar magnetic block, two magnetic sensing components, a storage, and a controller. After retrieving the current rotation angle by accessing a rotation angle table, the controller determines, by an encoding rule, digital logical values of a first phase signal (A-phase signal) and digital logical values of a second phase signal (B-phase signal) and outputs the digital logical values. The phase difference between a first phase signal and a second phase signal is adjusted, and a hysteresis range, also known as hysteresis angle, is adjusted, according to the grids attributed to the predetermined number of grids before the turning point and the grids attributed to the predetermined number of grids after the turning point. Hence, the non-contact adjustable hysteretic magnetic encoder features enhanced potential of expansion and marked industrial practicability.

  • Patent number: 9575143
    Abstract: The present invention discloses a design for a single-chip dual-axis magnetic field sensor, based on magnetic tunnel junction (MTJ) elements and permanent magnets integrated on a semiconductor substrate to produce two types of sensor bridges that detect orthogonal magnetic field components. The orthogonal magnetic field component detection capability results from the different types of sensor bridges that can be produced by varying the shape of the MTJ elements and the bias fields that can be created by permanent magnets. Because the permanent magnets can create orthogonal bias fields on the different sensor bridges, it is possible to use a single pinned layer to set direction for both sensor bridges. This is advantageous because it permits the two-axis sensor to be fabricated on a single semiconductor chip without the need for specialized processing technology such as local heating, or deposition of multiple magnetoresistive films with different pinned layers setting directions.

  • Patent number: 9537267
    Abstract: The present invention relates to squib connectors, for instance for airbag ignition systems, which allow the electrical or electronic monitoring of the correct coupling of a squib plug connector with its corresponding counterpart. According to the invention, a squib connector has at least two terminals having corresponding signal lines. In order to allow an electrical monitoring of the correct coupling of the plug connector, the terminals are in electrical contact with each other in the uncoupled or incorrectly coupled condition of the plug connector. This electrical contact between the terminals is configured to be separated upon correct coupling to a corresponding counter-connector either automatically or by an actuating action. The disconnecting of the terminals may then be monitored by any suitable monitoring means.

  • Patent number: 9528956
    Abstract: Methods and apparatus for measuring the cleanliness of molten metals. Direct current is passed between electrodes through molten metal advancing through a passage in an electrically resistive wall. A voltage signal is analyzed for the presence of solid generally non-metallic inclusions in the metal. Direct current is supplied by one or more ultra-capacitors and the decay in discharge voltage of the capacitor(s) is compensated for by passing the current from each capacitor through a resistor ladder network circuit having resistors connected in parallel. Individual resistors are switched on or off in a sequence effective to change the resistance of the circuit and maintain the current within a predetermined range. Heat generation and noise pick-up are minimized by maintaining a low discharge voltage and measurement current while using FETs only in the fully ON or OFF conditions to switch the resistors into or out of the circuits.
