Touch-sensitive device () that comprises a substrate () comprising a first set of holes extending in a first direction () through said substrate () whereby each hole forms an opening at a first side () of said substrate () and a second set of holes extending in a second direction () through said substrate () whereby each hole forms an opening at said first side () of said substrate (), where said second direction () intersects said first direction (). A transmitter () arranged to transmit electromagnetic radiation through said first set of holes, and a receiver () is arranged to receive electromagnetic radiation transmitted through said second set of holes, whereby the touch-sensitive device () is arranged to detect the presence and/or position of an object () on or above said first side () of said substrate ().

Touch-sensitive device and communication device

An electronic device comprises a housing having an outer face and an inner face. A key is provided on the housing, which comprises a micro hole formed in the housing and a conductive material extending within the micro hole to the outer face of the housing. A sensor is coupled to the conductive material to detect whether an object is brought into contact or out of contact with the micro hole at the outer face.

A device may include logic to play songs. The device may also include a two level display. A first level of the display may display information to a user of the device, where the information is not associated with a song. A second level of the display may display graphical information to the user while a song is being played by the device.

Graphical display

An electronic device includes a light source, which generates light in response to a signal, and a controller. Because the luminosity of the light source decays over time, the controller generates a utilization value based on a cumulative time that the light source is emitting light, and regulates the signal that is provided to the light source in response to the utilization value to at least partially compensate for decay in the luminosity of the light source.
