Touch sensitive control panel
First Claim
1. An apparatus for controlling functions of an appliance comprising:
- a touch-sensitive control panel having a plurality of proximity sensor areas;
driver circuitry operable to output detection signals in response to selection of the proximity sensor areas; and
a controller operable to receive said detection signals from the driver circuitry and activate different functions of the appliance in response thereto, wherein the controller is operable to activate at least one function of the appliance in response to receipt of a pre-determined combination of at least two of said detection signals.

Abstract
An apparatus for controlling functions of an appliance is described having a touch-sensitive control panel resistant to accidental activation. The touch-sensitive panel has a plurality of proximity sensor areas which may be selected by a user wishing to activate associated functions of the appliance. Driver circuitry coupled to the sensor areas is operable to output detection signals to a controller in response to a user selecting ones of the sensor areas. The controller is configured to activate functions of the appliance in response to these detection signals. For one or more functions of the appliance, for example a switching on function, the controller is configured to only activate the function when a user makes a pre-determined combination of at least two selections from the plurality of sensor areas. This reduces the chances of potentially dangerous functions being activated inadvertently and can further help a designer to provide an intuitive and uncluttered appearance to the control panel.
