An input organ, being provided with means for detecting the touch of a fingertip, where said organ is provided with means for providing a tactile feedback to said fingertip to acknowledge an activation of said input organ, and where said means for providing a tactile feedback comprises an elongate object of shape memory metal.
摘要:
Embodiments of the invention are directed to a method of keeping track of and staying tuned to a transmitter even when a receiver is moving at a relatively high speed. Electronic equipment carried on fast moving vehicles and comprising receiving means can experience a shift in the frequencies received due to Doppler shift. Embodiments provide a way of taking such a Doppler shift into account by means of acceleration measurements of the electronic equipment. Some embodiments may be used in electronic equipment containing a GPS receiver or the like, where re-tracking of satellites can be power and time consuming.
摘要:
An arrangement and method for displaying at least a first and a second image. The arrangement comprises at least one light source (120, 121, 220, 221, 320, 321) adapted to generate light having at least a first and a second light characteristic; and at least a first and a second image forming element (122, 123, 222, 223, 322, 323) arranged to display a first and a second image (128, 129, 230, 231), respectively. The first image forming element (122, 222, 322) is at least responsive to the light having the first light characteristic. The second image forming element (123, 223, 323) is at least responsive to the light having the second light characteristic.
