摘要： A battery pack includes a battery, a first temperature sensor configured to provide a first temperature value associated with a temperature of the battery, a heat source disposed proximate to the battery and configured to heat the battery, a second temperature sensor configured to provide a second temperature value associated with a temperature of the heat source, and a control board coupled to the first temperature sensor and the second temperature sensor, wherein the control board is configured to receive the first temperature value and the second temperature value. The control board is configured to compare the first temperature value and the second temperature value to determine a temperature gradient between the battery and the heat source and transmit an alert if the temperature gradient exceeds a first temperature gradient threshold.

摘要： The disclosed embodiments relate to the monitoring and control of additive manufacturing. In particular, a method is shown for removing errors inherent in thermal measurement equipment so that the presence of errors in a product build operation can be identified and acted upon with greater precision. Instead of monitoring a grid of discrete locations on the build plane with a temperature sensor, the intensity, duration and in some cases position of each scan is recorded in order to characterize one or more build operations.

摘要： A defect detection system and method for detecting the presence of a defect in an extruded strip can include various elements. In examples, a thermal imagining sensor is used to detect a plurality of surface temperatures on a surface of the extruded strip. A processing unit is configured to generate a thermal map of an area of the surface of extruded strip. The processing unit is further configured to determine whether the plurality of surface temperatures are outside a tolerance range, indicating the presence of a defect in the extruded strip. Detecting a defect during the extrusion process can help achieve the goal of reducing manufacturing waste and increasing quality control.

摘要： In accordance with an embodiment, a method includes: monitoring a temperature difference between two double-side cooled (DSC) power modules of a plurality of DSC power modules arranged in stacks of DSC power modules; comparing the temperature difference with a first temperature threshold; detecting a cooling pipe system blockage when the temperature difference is above the first temperature threshold; and after detecting the cooling pipe system blockage, disabling gate driver circuits coupled to the plurality of DSC power modules or operating the DSC power modules in a low-power mode. Each stack includes a plurality of DSC power modules. Each DSC power module has a top surface and a bottom surface, which are each thermally coupled with one or more cooling channels of a cooling pipe system. The two DSC power modules are thermally coupled with a same cooling channel of the one or more cooling channels.

摘要： 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).

摘要： Apparatus and associated methods relate to generating a trigger signal in response to detection of a triggering acoustic event sensed by one of a distributed network of optical acoustic sensors mechanically coupled to an aircraft structure. Each of the optical acoustic sensors is configured to generate an optical response signal indicative of an acoustic condition detected by the optical acoustic sensor. A controller receives the optical response signals and generates, if a triggering one of the optical response signals is indicative of a triggering acoustic event, a trigger signal. The controller also determines a location of the specific one of the distributed network of optical acoustic sensors that generated the triggering one of the optical response signals. In some embodiments, the trigger signal is sent to a Health & Usage Monitoring System configured to perform a health scan, in response to receiving the trigger signal, of the aircraft structure.

摘要： Methods and systems for inspecting insulated equipment for corrosion under insulation are provided. The system includes an autonomous unmanned vehicle having aerial and ground locomotive capabilities. The vehicle includes an infrared detector and a pulsed eddy current sensor. In the method, infrared waves emitted from the equipment are detected along the equipment with the infrared detector. Using the infrared detector, at least one image of an inner surface of the equipment is developed based on the detected infrared waves. At least one area that is susceptible to corrosion is determined based on the at least one image. The susceptible area is inspected with the pulsed eddy current sensor, which induces an eddy current in the inner wall of the equipment. Based on a rate of the decay in strength of the eddy current, it is determined whether corrosion exists at the susceptible area using a processor configured by code.
