Abstract: A liquid crystal display (LCD) having a temperature regulation framework which utilizes a digital to analog converter. The thermal management system involves display heating controlled based on temperature values calculated for the center of the display.

Abstract: A dental cleaning appliance includes a handle and a fluid delivery system for delivering a burst of working fluid to the teeth of a user. Part of the fluid delivery system is moveable relative to the handle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of that part of the fluid delivery system relative to the handle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

Abstract: A system for detecting errors in a source driver for an electronic display includes an upstream logic device, a comparator, and a source driver. The source driver has a number of driven channels which transmit active signals for generating an image on the electronic display and one or more dummy channels which transmit dummy signals to the comparator. The comparator receives and compares signals from at least some of the driven channels with the dummy channels and generates an alert for transmission to the upstream logic device if a mismatch is detected.

Abstract: An electrical assembly for detecting failures in an LCD source driver includes a plurality of active channels on the source driver which communicate electronically with an LCD. A split active channel on the source driver is provided with an original signal and splits the original signal into an active split channel and a dummy split channel. The active split channel is sent to the LCD. A microprocessor receives the dummy split channel and compares the received dummy split channel signal to the original signal.

Abstract: An electrical assembly and method for detecting failures in an LCD source driver is disclosed herein. A plurality of active channels are placed on the source driver which communicate electronically with an LCD. At least one dummy channel may be placed on the source driver which is driven with an original signal. A microprocessor may then receive the dummy channel and compare the received dummy channel signal to the original signal. An error message may be transmitted when the received dummy channel signal does not match the original signal. Alternatively, the source driver may be provided with a split active channel which is provided with an original signal that is split into an active split channel and a dummy split channel. While the active split channel is sent to the LCD, the dummy split channel is sent to the microprocessor for comparison with the original signal.

Abstract: A dental cleaning appliance includes a fluid delivery system for delivering a burst of working fluid to the teeth of a user; and a control circuit for controlling the delivery of the burst of working fluid to the teeth of a user. The appliance has a first operational mode in which the delivery of the burst of working fluid to the teeth of a user is inhibited and a second operational mode in which the burst of working fluid to the teeth of a user is permitted. During use of the appliance, the control circuit is arranged to effect a transition between the first operational mode and the second operational mode automatically depending on a detected operational parameter of the appliance.

Abstract: A dental cleaning appliance includes a handle, a fluid delivery system for delivering working fluid to the teeth of a user, and a control circuit for actuating the delivery of working fluid to the teeth of the user depending on a received input. For each input, the control circuit is arranged to actuate the delivery of a series of bursts of working fluid to the teeth of the user.

Abstract: A rinsing machine suitable for rinsing a washable dust mat is provided with first squeeze means, pressure means downstream of the first squeeze means and at least one intermediate squeeze means between the first squeeze means and the pressure means. Rinsing water is applied onto the mat between the pressure means and the last intermediate squeeze means, part of the rinsing water being allowed to pass upstream of each intermediate squeeze means in turn whereby the mat is rinsed at least twice from the single supply of rinsing water. The means which allow part of the rinsing water to pass upstream of each intermediate squeeze means is disposed within the length of the respective intermediate squeeze means. A washing machine comprises the rinsing machine and discharge means upstream of the first squeeze means for flushing a mat with a washing liquid.
