Methods, apparatuses, systems and computer program products are disclosed to estimate road surface temperature for a geographic location. Reference ambient sensor data indicative of ambient conditions in vicinity to mobile vehicles are retrieved. Reference roadside sensor data indicative of at least road surface temperature in vicinity to distributed roadside sensors are retrieved. A relationship is established between the reference ambient sensor data and road surface temperature, based on the reference ambient sensor data and based on the reference roadside sensor data. A data structure is created, encoding the established relationship. Further, current vehicle ambient sensor data, indicative of current ambient conditions in vicinity to the one or more vehicles, are collected at one or more vehicles. Finally, a road surface temperature estimate is determined for the geographic location, using the data structure and using the collected current vehicle ambient sensor data.

A high-temperature biaxial strength tester for a CMC turbine vane includes a test stand, a thermal insulation box, a vane fixture, a biaxial loading device, thermocouples, a multi-channel thermometer, quartz lamps, a digital image correlation (DIC) system, and a cooling circulation system.

A charging system for a battery-operated machine is disclosed. The charging system includes a charging receptacle having a power connection and a signal connection, with the charging receptacle configured to receive electrical current via the power connection from a power supply plug. The charging system further includes a heat rejection element thermally coupled to the charging receptacle, a temperature sensor, and a charging controller operatively coupled to the temperature sensor and the charging receptacle. The charging controller is configured to receive a temperature signal from the temperature sensor, the temperature signal being indicative of a charging-receptacle temperature. The charging controller is further configured to transmit, via the signal connection to the connected plug, a control signal to adjust (e.g., raise or lower) the electrical current supplied to the power connection.

A temperature sensing system for a resistive welding process for a tube performs repeatable temperature measurement using a camera to detect multiple distinct visible light wavelengths even as the ambient environment in the view path changes. Sensed colors in a field of view in the vicinity of a weld are output to a computing element that calculates a corresponding temperature and alerts an operator when the sensed color exceeds a preset color range.
