Abstract: A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user. The nozzle moves 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 nozzle 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. The control circuit is configured to adjust a parameter of the delivery to the teeth of the user, such as the volume of working fluid within a delivery, depending on the variation with time of the output from the sensor.

Abstract: A haircare appliance has a housing having an air inlet and an air outlet, an airflow generator for generating an airflow from the air inlet to the air outlet, and a heater for heating the airflow. The haircare appliance has an airflow temperature module for obtaining a value indicative of a temperature of the airflow at the air outlet, a distance sensor for sensing a distance to hair within a flow path from the air outlet and a temperature sensor for sensing a temperature of the hair. The haircare appliance has a moisture estimation module configured to estimate, based on received output values from the airflow temperature module, the distance sensor and the temperature sensor, a moisture content of the hair.

Abstract: A hair styling appliance is described that includes an airflow unit for generating an airflow, a heating unit for heating the airflow, and a control unit for controlling the airflow unit and the heating unit. The control unit controls the airflow unit and the heating unit in a predefined sequence of modes that includes a first mode, a second mode and a third mode. The airflow unit has a different flow rate and/or the heating unit has a different heat setting in each of the modes, and the control unit determines when to transition between modes of the predefined sequence.

Abstract: A hair styling appliance is described that includes an airflow unit for generating an airflow, a heating unit for heating the airflow, and a control unit for controlling the airflow unit and the heating unit. The control unit receives user data relating to at least one of a desired style, a hair type and a previous styling by the appliance. The control unit controls the airflow unit and the heating unit in a sequence of modes to style the hair of a user, the airflow unit having a different flow rate and/or the heating unit having a different heat setting in different modes. The control unit uses the user data to define the sequence of modes.

Abstract: A haircare appliance has a main body housing an airflow generator for generating an airflow, an intermediate attachment for detachably connecting to the main body, and a hair treatment attachment for detachably connecting to the intermediate attachment. The intermediate attachment has an inlet for receiving the airflow from the main body and an outlet for emitting the airflow. The hair treatment attachment is configured to receive the airflow from the outlet of the intermediate attachment and emit the airflow towards hair to be treated in use. The intermediate attachment has a sensor module for sensing a property of at least one of hair to be treated and the hair treatment attachment.

Abstract: A haircare appliance is provided for detecting a hair moisture content. The haircare appliance includes a processing element, at least one light emitting element emitting at least two wavelengths, and a sensor element, wherein the light emitting element is adapted to irradiate a portion of hair to be treated. The sensor element is adapted to receive a sensor reading from an acquisition region of the irradiated hair and generate a sensor signal dependent on the sensor reading and includes a spectral sensor element. The processing element is adapted to determine a moisture content of at least the irradiated portion of the hair from the sensor signal.
