  • Patent number: 10297300
    Abstract: A method for measuring a temperature of magnetic junction switchable using spin transfer. The magnetic junction includes at least one magnetic layer. The method includes measuring a temperature variation of at least one magnetic characteristic for the magnetic layer(s) versus temperature. The method also includes measuring a bias variation in the magnetic characteristic versus an electrical bias for the magnetic junction. This measurement is performed such that spin transfer torque-induced variation(s) in the magnetic characteristic(s) are accounted for. The temperature versus the electrical bias for the magnetic junction is determined based on the temperature variation and the bias variation.

  • Patent number: 10288513
    Abstract: A combined pressure and temperature sensing device includes a sensor port geometry that provides improved contact between a fluid media being measured and a thermistor cavity of the sensor port. The increased contact area provides improved response time and accuracy compared to previously known integrated pressure-temperature sensors. A temperature sensor element is offset from a pressure sensor element relative to a central axis of the temperature-pressure sensor body/package to facilitate substantially increasing a pressures sensor cavity volume without increasing the overall sensor port diameter. A wire-bondable thermistor support portion facilitates high volume automated production line. The temperature sensing element may be resistance welded to the thermistor support portion in a parallel manufacturing process.

  • Patent number: 10247617
    Abstract: Middle-of-line (MOL) metal resistor temperature sensors for localized temperature sensing of active semiconductor areas in integrated circuits (ICs) are disclosed. One or more metal resistors are fabricated in a MOL layer in the IC adjacent to an active semiconductor area to sense ambient temperature in the adjacent active semiconductor area. Voltage of the metal resistor will change as a function of ambient temperature of the metal resistor, which can be sensed to measure the ambient temperature around devices in the active semiconductor layer adjacent to the metal resistor. By fabricating a metal resistor in the MOL layer, the metal resistor can be localized adjacent and close to semiconductor devices to more accurately sense ambient temperature of the semiconductor devices. The same fabrication processes used to create contacts in the MOL layer can be used to fabricate the metal resistor.

  • Patent number: 10234337
    Abstract: The light source unit generates probe light. The splitting unit splits Brillouin backscattered light, which arise in the optical fiber under test owing to the probe light, into two branches of a first light path and a second light path. The delay unit gives a delay between light propagating through the first light path and the second light path. The multiplexer unit multiplexes light propagating through the first light path and the second light path to generate multiplexed light. The coherent detection unit performs heterodyne detection on the multiplexed light to output a difference frequency as a first electrical signal. The frequency shift amount obtaining unit performs homodyne detection on one of the two branches split from the first electrical signal and the second electrical signal having the same frequency as the frequency of the first electrical signal to obtain a frequency shift amount.
