A method, apparatus and computer program are provided for reducing the effect of electromagnetic noise on images displayed by a television display (101). A camera (100), when directed towards the display (101), generates image data representing at least a portion of an image being displayed. The image data are analysed by a controller (102) to identify a presence, in the at least a portion of an image being displayed, of one or more in a predetermined set of image artefacts known to result from the presence of electromagnetic noise. Filter characteristics are determined, for use by a configurable filter (104) in the television, corresponding to an identified image artefact. The generated signals are sent to the configurable filter (104) to implement the determined filter characteristics, thereby to reduce the presence of the identified image artefact. The process may be operated iteratively to improve the image quality.

A method is provided for operating a cooker having at least one overflow sensing element associated with a heating element of the cooker, the at least one overflow sensing element having a measurable characteristic. The method comprises: (i) making measurements of the measurable characteristic for the at least one overflow sensing element; (ii) determining, using measurements made at (i) during a calibration period, a reference value for the characteristic for the at least one overflow sensing element; (iii) comparing a subsequent measurement made at (i) with the respective reference value for the characteristic thereby to identify an overflow event if a determined difference between the subsequent measurement and the respective reference value of the characteristic exceeds a predetermined threshold; and (iv) if an overflow event is identified at (iii), generating a warning for a user. The invention extends to a cooker, a cooker controller and a computer program.

The present invention provides a video display apparatus (100) at least comprising a display screen (10), at least one loudspeaker for emitting a sound in association with at least one still or moving image displayed on the display screen (10), at least two spatially separated microphones (1, 2, 3), and an audio signal processing unit (20) configured to separate the sound emitted by the loudspeaker from a sound received by the microphones. The present invention also provides a method of operating a video display apparatus, wherein the method at least comprises displaying on a display screen of the apparatus at least one still or moving image, emitting a sound from a loudspeaker of the apparatus in association with displaying the at least one still or moving image, receiving a sound by at least two spatially separated microphones of the apparatus, and separating the sound emitted from the loudspeaker from the sound received by the microphones. Such a method allows for three-dimensional localization and separation of sound sources to receive and execute voice commands for control of a video display apparatus, such as a television, without the need for a remote control.

The temperature of a hair iron (100) is controlled to prevent damage to hair being ironed by the hair iron (100). Whilst the hair iron (100) is being applied to the hair, the controller determines a temperature change of one or more plates (102) of the hair iron (100) over a time period starting from an initial application of the hair iron (100) to the hair being ironed. If the temperature change of the one or more plates (102) is larger than a threshold, the controller reduces the power supplied to the one or more plates (102).
