  • Patent number: 9116199
    Abstract: A single package magnetoresistive angle sensor for use in measuring rotation angle of a magnet is disclosed. The magnetoresistive angle sensor comprises a pair of magnetoresistive sensor chips, wherein one of the chips is rotated by 180-degree rotation relative to the other. The magnetoresistive sensor chips are attached to a standard semiconductor package lead frame to form a single-axis push-pull full-bridge sensor. Each of the magnetoresistive sensor chips comprises a pair of magnetoresistance sensor arms. Each magnetoresistive sensor arm comprises one or more GMR or MTJ sensor elements. The GMR of MTR sensor elements utilize a pined layer. The element blocks of the magnetoresistive sensor electrically are interconnected and connected to the package leads by wirebonding. The magnetoresistive angle sensor can be packaged into various standard semiconductor package designs.

  • Publication number: 20150090553
    Abstract: The present invention provides a bogie for a rail vehicle, including: two pairs of wheel sets arranged frontward and backward (51), axle boxes (52) respectively fixedly arranged at both ends of a central rotating shaft of the wheel set, and a frame arranged on two axle boxes on the same side (50), and further including: a current collector mounting plate (53) that is fixedly mounted with a current collector, with both ends of the current collector mounting plate being respectively fixedly connected to the two axle boxes on the same side. In the bogie for the rail vehicle, the current collector is fixedly connected on the axle box, and thus has the same state of motion as the axle box, effectively reducing the displacements of the current collector in all directions relative to the third rail during operation, and reducing vibration and impact suffered by the current collector.

  • Patent number: 8936157
    Abstract: An indexing cap assembly indexes visual cues or indicia during an open and close cycle so as to help users more easily track container entry as for example with regard to medications so as to ensure proper dosage. The indexing cap assembly basically incorporates six components, including a cover construction, an indexing plate or wheel, a compression coil or spring, a push plate construction, a gear tray or swing plate construction, and an assembly ring. The cover construction and assembly ring are joined together to essentially form or close the cap assembly with the other parts coaxially aligned and operable therebetween. The indexing wheel is rotatively received within the cover construction such that axial displacements of the push plate advance the indexing wheel and indicia upon its upper surface are sequentially revealed by way of the window formed in the cover construction.
