Various techniques are disclosed for providing a device attachment configured to releasably attach to and provide infrared imaging functionality to mobile phones or other portable electronic devices. For example, a device attachment may include a housing with a tub on a rear surface thereof shaped to at least partially receive a user device, an infrared sensor assembly disposed within the housing and configured to capture thermal infrared image data, and a processing module communicatively coupled to the infrared sensor assembly and configured to transmit the thermal infrared image data to the user device. Thermal infrared image data may be captured by the infrared sensor assembly and transmitted to the user device by the processing module in response to a request transmitted by an application program or other software/hardware routines running on the user device.

A thermal sensor may include a housing having a thermal contact member, an indicator coupled to the housing, and a thermal sensing element disposed in the housing in thermal communication with the thermal contact member. The thermal sensor may also include an actuator element in communication with the indicator and thermal sensing element. The thermal sensing element may be configured to expand in response to reaching a temperature threshold thereby engaging the actuator element and activating the indicator.

A thermal displacement correcting apparatus includes a correction amount estimating device and a parameter automatic selecting device that, in a machine tool having two different sets of specifications that differ due to the presence/absence of a scale and different methods of measuring the lengths of a bed and a table, estimate a thermal displacement correction amount of the machine tool of each set of specifications. The two devices store a collection of parameters for an estimated thermal displacement calculation corresponding to each of the bed, the scale, the table, and a workpiece, as a database, and select the parameters belonging to the set of specifications from the database based on machine information according to each set of specifications, calculate estimated thermal displacements of the bed, the table, and the workpiece, or also the scale, according to the selected parameters, and combine the estimated thermal displacements.

A processing apparatus and a method capable of accurately measuring a real temperature of a workpiece contained and heated in a chamber. The processing apparatus includes a chamber containing a workpiece, a measurement piece installed in the chamber, and a measuring unit. The measurement piece is capable of thermal expansion and contraction in response to an internal temperature of the chamber. The measuring unit measures a thermal expansion and contraction amount of the measurement piece to thereby measure the real temperature of the workpiece.

Techniques for real-time virtual sensing of an axle assembly temperature include determining, at a controller of a vehicle, an initial temperature of an axle assembly of the vehicle based on an ambient temperature and a fluid temperature of a transmission. The techniques include determining, at the controller, an operating mode of the vehicle, the operating mode of the vehicle being one of moving and non-moving. The techniques also include estimating, at the controller, a temperature of the axle assembly based on the initial axle assembly temperature and the vehicle operating mode using an axle temperature model.

An EUV light source target material handling system is disclosed which may comprise a droplet generator having a target material reservoir in which the target material may be replenished while a nozzle portion of the droplet generator is maintained at temperature. Also disclosed is a system for selectively draining spent target material.

A method of detecting thermal hotspots in a power distribution system is provided. The power distribution system includes a conductive hub including a connection point for coupling to an electrical distribution component. The method includes measuring a first temperature of the conductive hub at the connection point, estimating a second temperature of the conductive hub at the connection point, and determining when a difference between the first temperature and the second temperature exceeds a first predetermined threshold. The estimation based at least partially on an amount of electric current flowing through the conductive hub.
