20120169530 | PORTABLE HOUSINGS FOR GENERATION OF BUILDING MAPS - A system and method are presented for producing a model of the interior of a building. The model is capable of receiving and dynamically incorporating input from various sources including, for example, existing static map data, data such as annotations and updates provided by persons on the scene but outside the building, and real-time data from sensors located on mobile persons or assets that are dynamically moving inside the building. In some cases, the moving persons or assets inside the building may carry a unit that emits sound or electromagnetic pulses, which reflect off the immediate surroundings in a particular room or portion of the building, and sense the reflected pulses. The reflections from relatively close features may arrive at the sensor more quickly than those from relatively distant features, so that temporal analysis of the reflected pulse may provide information about features in the building as a function of their distance away from the unit. Pulses may be emitted and received at multiple locations in a room or portion of the building. The reflected pulses may be analyzed, using specific time shifts that correspond to round-trip travel times in particular directions, so that the actual locations of features may be identified. By walking from room-to-room throughout the interior of a building and performing such analysis, much or all of the interior of a building may be mapped. | 07-05-2012 |

20130214776 | TUNNELING MAGNETO-RESISTIVE DEVICE WITH SET/RESET AND OFFSET STRAPS - A sensing device exhibits a tunneling magneto-resistive (TMR) effect, and changes electrical resistance in response to a magnetic field. A first current carrying conductor is positioned in proximity to the TMR sensing device, such that upon an application of a sufficient current, a magnetic field is generated. The magnetic field is sufficiently strong and properly oriented so as to cause a magnetization of a soft magnetic layer of the TMR sensing device, thereby causing a change of the TMR sensing device from one bi-stable state to another bi-stable state. | 08-22-2013 |
