| 20100052424 | METHODS AND APPARATUS FOR INTEGRATED CIRCUIT HAVING INTEGRATED ENERGY STORAGE DEVICE - Methods and apparatus for a sensor to provide a sensor output, an integrated circuit module formed at least partially on a substrate to receive the sensor output and provide an IC output signal, an output circuit having a voltage input to receive a voltage supply signal via a switch element and a signal input to receive the IC output signal and an output to provide a voltage output signal, and an integrated power storage element coupled to the voltage input of the output circuit to provide power during an interruption of the voltage supply signal, wherein the power storage element includes at least one layer generally parallel to the substrate. | 03-04-2010 |
| 20100188078 | MAGNETIC SENSOR WITH CONCENTRATOR FOR INCREASED SENSING RANGE - A sensor that includes a magnetic flux concentrator is presented. The sensor includes a sensor integrated circuit with a structure that includes a magnetic field sensor to sense a magnetic field generated by an external magnetic flux source comprising a magnetic article. The stricture has a first surface to face the external magnetic flux source and an opposing second surface. The sensor integrated circuit also includes a lead frame connected to the structure and having a base portion with a first base portion surface to support the stricture and an opposing second base portion surface. Also provided in the sensor is a magnetic flux concentrator to concentrate magnetic flux of the magnetic field. The magnetic flux concentrator can be disposed proximate to the second base portion surface such that the structure and lead frame base portion are located between the magnetic flux concentrator and the external magnetic flux source when the sensor integrated circuit is positioned relative to the external magnetic flux source. | 07-29-2010 |
