Abstract: A system includes a plurality of digital-to-analog converter (DAC) channels. Each DAC channel includes a current control circuit which receives a start limit signal or an end limit signal. The current control circuit reduces an output current limit of the channel responsive to the start limit signal and increases the output current limit responsive to the end limit signal. Each channel includes a current sensor circuit adapted to measure the output current of the channel and provide a channel over-current alert signal if the output current rises above a high current limit. The system includes a controller which asserts the start limit signal if the number of channels exceeding the high current limit is greater than a maximum allowable number and asserts the end limit signal if the number of channels exceeding the high current limit is less than the maximum allowable number minus a hysteresis value.

Abstract: Belt tensioning monitoring device for monitoring the belt tensioning of a belt of a belt drive system having a driving pulley and a driven pulley rotated by the driving pulley. The belt tensioning monitoring device is configured to determine the belt slip effect with at least one mark provided on the belt and a sensor configured to detect the mark and to send a signal to an electronic control unit.

Abstract: Systems and methods for making and using a flow-thru mounting device are described herein. The mounting device can include an adjustable fastening device and a flow-thru bracket, which is coupled to the fastening device. The fastening device may include a first contact surface near a first end of the fastening device and a second contact surface near a second end of the fastening device. The fastening device can be adjusted so that a user selectively increases and/or decreases the distance between the first and second contact surfaces. In this manner, the user can secure the mounting device to an object, such as a transformer. The flow-thru bracket can be configured to receive a mating component of a flow-thru. Accordingly, the mounting device can receive a flow-thru and attach that flow-thru at one or more locations on or within a transformer box. Other embodiments are described.

Abstract: An insulated door for use in a refrigerator having an ice and water through the door dispenser is made by attaching a liner for housing the dispenser on the rear face of the door in line with a front opening. The liner is secured to the door as are the hinge bearings and a tube extends between the liner and the lower hinge bearing for conducting electrical wires and a water tube. The only opening in the liner is at a point to receive ice cubes from the dispenser in the refrigerator and this opening is covered prior to foaming. The door is placed in a foaming fixture which completely enclosed and supports the door and the liner and foam is injected so that the foam, when expanded and hardened, completely covers the rear face of the door. After the door is removed from the foaming fixture, the thin layer of foam at the inlet opening is cut away and the door is completed by adding the liner and the gaskets and other hardware as well as the dispensing unit itself.
