A detection apparatus and a server are provided, where the apparatus is configured to detect whether a coolant heat pipe or a solenoid valve on the coolant heat pipe in a device is abnormal, and the apparatus includes a control chip. The control chip can control a working state of the solenoid valve. The control chip can further obtain a temperature of a component in the device. When it is detected whether the coolant heat pipe or the solenoid valve is abnormal, the control chip may obtain a temperature difference of the component in the device when the working state of the solenoid valve is controlled, and relatively conveniently determine whether the coolant heat pipe or the solenoid valve is abnormal based on the temperature difference.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

A method and apparatus may include activating, by a network node, power of a global-positioning-system receiver or power of an active antenna of the global-positioning-system receiver. The apparatus uses the global-positioning-system receiver to perform synchronization of the apparatus. The method may include receiving at least one measurement, wherein the at least one measurement comprises real-time, predictive, or historic data. The method may also include determining a holdover duration based on the at least one measurement. The holdover duration corresponds to a length of time where the power of the global-positioning-system receiver or the power of the active antenna is to be turned off. The method may also include deactivating the power of the global-positioning-system receiver or the power of the active antenna for the holdover duration.

A device that measures a temperature of a heat plate for heating a target substrate mounted thereon, includes: a temperature measurement substrate including a substrate body and temperature sensors installed in the substrate body; a memory part to store correction parameters over a plurality of time zones after the temperature measurement substrate is mounted on the heat plate; and a data processing part configured to acquire time transition data of a temperature by correcting respective temperature detection values sampled at predetermined time intervals after the temperature measurement substrate is mounted on the heat plate, using the correction parameters stored in the memory part in a corresponding relationship with the temperature sensors and the time zones. The correction parameters are obtained in advance based on a standard temperature transition data acquired in advance using the temperature sensors and a time transition data acquired by each of the temperature sensors.

A method operates a power converter that contains power converter arms. Each of the power converter arms has switching modules and each of the switching modules has a plurality of semiconductor switches and an energy store. A temperature value for the power converter is ascertained on the basis of a state model of the power converter, wherein the ascertainment is repeated so as to obtain time-related temperature values. A number and a magnitude of temperature swings that have occurred are ascertained from the temperature values, and a remaining service life for the power converter is estimated based on the ascertained number and magnitude. A power converter is configured to carry out the above-described method.

An adaptive method and system for monitoring a shipping container for an environmental anomaly uses sensor-based ID nodes within the container and a command node. Sensors on each ID node generate sensor data about an environmental condition proximate the ID node as disposed within the container. Each ID node periodically broadcasts the sensor data. The command node monitors a first group of sensor data from the ID nodes over a first time period to detect an initial environmental threshold condition related to the container, then monitors a subsequent group of sensor data over a second time period under a modified monitoring parameter to detect a secondary environmental threshold condition related to the container as the anomaly. In response to detecting the secondary condition, the command node generates an alert notification and transmits the alert notification to an external transceiver to initiate a mediation response related to the anomaly.
