  • Patent number: 10006817
    Abstract: A meat probe has a shaft, plug, and stabilizer for measuring a parameter (e.g., temperature) of a piece of meat and communicating the measurement to a cooking appliance. The stabilizer may have a plurality of wings. For example, two wings may be cantilevered about a proximal end that is at the shaft. As the shaft is inserted into the piece of meat, the wings are bent outwardly about the proximal end. In another example, four wings are connected on opposite ends to a first and second base, and the shaft extends through the first and second bases. As the shaft is inserted into the piece of meat, the second base is pushed upward, decreasing the distance between the first and second base and bending the wings about a middle portion.

    Abstract: An electronic device that determines an external temperature is described. During operation, the electronic device uses a sensor mechanism (such as an integrated temperature sensor) to determine an internal temperature of the electronic device. Then, a thermoelectric device (which may be based on the Peltier effect and/or the Seeback effect) determines the relative temperature difference between the internal temperature and the external temperature. Next, the external temperature may be determined based on the internal temperature and the temperature difference. For example, the external temperature may be determined relative to a threshold value. Furthermore, an electrical signal (such as a voltage or a current) output by the thermoelectric device may be used to recharge a battery and, more generally, a power source in the electronic device.

  • Patent number: 8876373
    Abstract: A protective cover for an insertion probe of a medical instrument. The cover contains a flexible tubular body that compliments the probe geometry and a radially disposed flange that surrounds the proximal end of the body. A series of snap-on fasteners removably connect the cover to the instrument. A camming surface is located on the outer face of the flange which coacts with a cam follower that is movably mounted upon the instrument to flex the cover sufficiently to open the fastener and release the cover from the instrument and move the cover axially toward the distal end of the tip.

  • Patent number: 8847586
    Abstract: A magnetic sensor inspection apparatus has a rectangular frame including a stage, a probe card, and a plurality of magnetic field generating coils. A wafer-like array of magnetic sensors is mounted on the stage, which is movable in horizontal and vertical directions. The probe card includes a plurality of probes which are brought into contact with a plurality of magnetic sensors encompassed in a measurement area. The magnetic field generating coils are driven to generate a magnetic field toward the stage. A plurality of magnetic field environment measuring sensors is arranged in the peripheral portion of the probe card surrounding the probes. A magnetic field controller controls magnetic fields generated by the magnetic field generating coils based on the measurement result of the magnetic field environment measuring sensors. Thus, it is possible to concurrently inspect a wafer-like array of magnetic sensors with the probe card.
