Abstract: A hair styling appliance includes elements moveable relative to each other, including a first arm and a second arm coupled together for reciprocal movement towards and away from each other, the first and second arms being arranged to receive hair within a region between each other. A sensor arrangement includes at least a first sensor component mounted to at least one of the elements and is configured to sense, using the first sensor component, a change in relative position of at least two of the elements. The sensor arrangement outputs a first signal indicative of an angle and/or a distance between the first arm and the second arm based on the sensed change in relative position.

Abstract: A headgear is described that includes a first air purifier, a second air purifier, a first microphone, a second microphone, and a control unit. The control unit analyses a first signal output by the first microphone and a second signal output by the second microphone to determine a direction of wind. The control unit then controls the relative flow rates of the first air purifier and the second air purifier in response to the determined direction of wind.

Abstract: A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. Magnets, connected respectively to the piston and the drive, enable the drive to couple to the piston and move it within the fluid chamber to draw fluid into the fluid chamber. A stop prevents the piston from being pulled beyond a stop position so that through continued actuation of the drive the magnets separate to allow a spring to push the piston away from the stop position to urge a burst of fluid from the fluid chamber.

Abstract: There is provided an ear cup including a housing containing a filter assembly and a motor-driven impeller for creating an airflow through the filter assembly, the housing including an air outlet downstream from the filter assembly for emitting the filtered airflow from the housing. The ear cup further includes an acoustic driver carried by or mounted to, either directly or indirectly, the housing, a reference internal noise sensor disposed within the housing, and a reference ambient noise sensor carried by or mounted to, either directly or indirectly, the housing. The ear cup further includes active noise control circuitry that is configured, in a first operating state, to use a signal provided by the reference internal noise sensor to operate the acoustic driver and, in a second operating state, to use a signal provided by the reference ambient noise sensor to operate the acoustic driver.

Abstract: There is provided an ear cup comprising a housing, an ear pad attached to the housing and arranged such that the housing and the ear pad together define a cavity having an opening, and an acoustic driver disposed within the cavity. The ear cup further comprises a feedforward microphone, a feedback microphone, and active noise control (ANC) circuitry. The active noise control (ANC) circuitry is configured to use a feedforward signal provided by the feedforward microphone to operate the acoustic driver to attenuate noise having frequencies within a feedforward ANC range having a lower limit of no less than 300 Hz and an upper limit of more than 1.5 kHz and to use a feedback signal provided by the feedback microphone to operate the acoustic driver to attenuate noise having frequencies within a feedback ANC range having an upper limit of no more than 1.5 kHz.
