A heating fluid control system determines the aggregated demand for heating fluid from a plurality of sources of demand in a building and deactivates a boiler that provides the heating fluid when the aggregated demand is zero. The sources of demand can include radiators and domestic hot water fixtures. Valves that control the flow of heating fluid from the boiler to these sources of demand can transmit signals representative of the position of the valve. A controller can use these signals and other signals to determine the demand for heating fluid from each source of demand. The controller evaluates the signals to determine the aggregate system demand. And after deactivating the boiler, the controller can reactivate the boiler when the aggregate system demand is determined to be non-zero. Methods of using such heating systems are also disclosed.

A heated blanket is presented that includes a self-regulating heating element contained therein for uniform heating of the heated blanket.

In an example, a server system is provided. The server system includes a frame including a support structure and a server supported by the support structure. The server system includes an actuator configured to cause the server to transition from a first position to a second position to increase exposure of the server to airflow to transfer heat away from the server via convection. The actuator is also configured to cause the server to transition from the second position to the first position to decrease exposure of the server to the airflow.

A ducting system has a first upstream location is to be connected to a first source of air. A downstream location in the duct is to be connected to a second source of air. The upstream location has a first valve, and the downstream location has a second valve. An end location of the duct is to be connected to a sink. A control for the valves achieves a desired pressure and temperature of air at the end location. The first temperature sensor is located at a position intermediate the upstream location and the downstream location. A second temperature sensor is located at a position intermediate the downstream location and the end location. A control is programmed to determine the health of the first and second valves based upon a difference between temperatures sensed by the first and second sensors. An air use system and a method are also disclosed.

Provided is an oscillator including: a resonator; a first circuit device electrically coupled to the resonator; and a second circuit device. The first circuit device generates a first clock signal by causing the resonator to oscillate, and performs first temperature compensation processing for temperature compensating a frequency of the first clock signal. The second circuit device receives the first clock signal from the first circuit device, generates a second clock signal based on the first clock signal, and performs second temperature compensation processing for temperature compensating a frequency of the second clock signal.

A temperature-sensing device configured to monitor a temperature is disclosed. The temperature-sensing device includes: a first capacitor comprising a first oxide layer with a first thickness; a second capacitor comprising a second oxide layer with a second thickness, wherein the second thickness of the second oxide layer is different from the first thickness of the first oxide layer; and a control logic circuit, coupled to the first and second capacitors, and configured to determine whether the monitored temperature is equal to or greater than a threshold temperature based of whether at least one of the first and second oxide layers breaks down.

Drapes for covering fluid heating devices having basins. Some drapes have a set of at least one positioning component trapped between the drape basin layer and the drape device layer by a set of bonds. The positioning component aligns the drape with the basin bottom. Optionally, the drape may have a low-slip film for basin contact and a non-slip film for at least a portion of the drape beyond the basin. Alternatively, a single layer drape may have a set of at least one positioning component bonded to the drape. Some drapes have basin-shaped sterile vented barrier with vents to allow the sterile vented barrier to be inserted into the basin and to vent air out of the basin. The heating system for the fluid heating device may interrupt electricity provided to a heating element when a temperature sensed at an air gap detector exceeds a high temperature setpoint.
