    摘要: A transmission in combination with a temperature measurement device and a device exterior to the transmission. The transmission includes a rotatable housing which drives a wheel of a vehicle, a wireless transceiver in communication with a thermistor embedded within molding, a battery embedded within the molding, and the molding resides within the housing. The temperature measurement device resides in a wall of the rotatable housing and the rotatable housing includes an interior volume. The interior volume of the rotatable housing is partially filled with oil for lubrication of transmission components residing within the interior volume of the housing. The temperature measurement device is rotated through the oil and out of the oil within the rotating housing when the rotating housing is in motion. The wireless transceiver is in communication with the device exterior to the transmission and communicates a temperature measurement from the temperature sensor and battery state of charge information to the device exterior to the transmission.

    摘要: A vapor deposition system fixture comprises an arm, a rake, a crown gear bearing assembly, a workpiece holder, a thermocouple, and a contact ring assembly. The crown gear bearing assembly is attached to and rotatably engaged with the rake and includes stationary portion and rotating portions. The workpiece holder is configured to rotate with the rotating portion. The thermocouple is configured to rotate with the workpiece holder. The contact ring assembly comprises a housing, a cover, first and second rotating contact rings, and first and second stationary contact rings. The housing is attached to at least one of the arm and the rake. The first and second rotating contact rings are electrically connected to the thermocouple. The first and second stationary contact rings surround the rotating ring. The first and second stationary contact rings are configured to receive an electrical signal from the first and second rotating contact rings.

    摘要: To provide a controller for rotary electric machine which can estimate a transitional temperature with good accuracy, while considering the heating amount and the heat radiation amount due to copper loss and iron loss which change according to the operating point of rotational speed and torque, and suppressing the increase in arithmetic load. A controller for rotary electric machine, at calculation timing of every estimation calculation period, by referring to a temperature prediction data in which a relationship among a rotational speed, a torque information, a temperature at a reference time point, and a temperature after lapse of the estimation calculation period from the reference time point, calculates an estimation value of temperature after lapse of the estimation calculation period from the last time calculation timing, corresponding to the present rotational speed, the present torque information, and the estimation value of temperature calculated at the last time calculation timing.
