Abstract:
A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, visible light from an intense visible light source(s) is directed at the resulting glass and thermal imaging is used to detect inclusions based on a temperature difference between the inclusions and surrounding float glass. In another example embodiment, inclusion detection may be performed without exposure of the glass to light from a light source(s). Inclusions and surrounding glass may cool at different rates and be at different temperatures just prior to and/or after an annealing lehr, and a difference in residual temperature between inclusions and surrounding glass may be detected via thermal imaging and identified to identify inclusion(s).

Abstract:
A housing assembly includes a base and a front assembly assembled with the base. The base includes a bottom and a sidewall that surrounds a peripheral edge of the bottom, and the front assembly is configured to engage with the sidewalls and close an open end of the base. The front assembly includes a latch that protrudes inward from an inner surface, and a spring-biased cam is rotatably supported on the base. The cam includes a cam surface that is engaged with the latch in such a way that rotation of the cam about the rotational axis results in a translation of the front assembly relative to the base in a direction parallel to the cam rotational axis. The cam is manually actuated using a tool.

Abstract:
A system and method to detect a foreign object proximate to a source resonator that is part of a wireless energy transfer system. The wireless energy transfer system may be one used to wirelessly charge the batteries of an electric vehicle. Data from a visible light camera and a multiple zone temperature sensor are combined or fused to determine whether a foreign object, such a metallic object or an animal, is in the vicinity of, or in close proximity to, a source resonator. The system controls an electric current provided to the source resonator based on whether a foreign object is detected to reduce or inhibit energy emitted by the source resonator. The visible light camera may be a monochrome or color camera and the temperature sensor may be an infrared camera or a thermopile array.

The microbolometric matrix contains equipment for the evaluation of the frequency of individual temperatures and their time- courses. The ambient environment parameter scanning device is preferably equipped with an ambient environment temperature scanner. The microbolometric matrix can be linked to the assessment unit using a card or cable. The ambient environment parameter scanning device can be linked with the evaluation and assessment unit either by Wi-Fi or cable.

Abstract:
A paint curing oven may include multiple infrared temperature sensors to indirectly measure the temperature of a painted object as the object is conveyed through the oven. In some examples, temperature measurements from the infrared temperature sensors are compared to temperature measurements from a temperature sensor physically carried by the painted object to develop a calibration relationship. In subsequent use in which the infrared temperature sensors measure the temperature of a painted object that does not carry a temperature sensor, the calibration relationship may be used to generate a simulated temperature curve. The simulated temperature curve may provide an estimate of the temperature of the painted object as would be determined by a temperature sensor physically carried by the painted object, were the painted object actually carrying the temperature sensor.
