摘要:
An integrated keymat or keyboard to be used on an electronic device. The integrated keymat includes a plurality of individual emissive keypads each having a legend or symbol provided thereon. The emissive keypad has a light-emitting source and a plurality of electrodes, operatively connected to a power source, to activate the light-emitting source in order to illuminate the keypads, wherein the connection of the electrodes is controllable so that one or more keypads can be illuminated causing the key indicating marks on said one or more keypads to become more visible. Furthermore, the light-emitting source may include a plurality of segments of pixels which are individually addressable so that they can be selectively activated to form an alphanumeric symbol or pattern. Moreover, the integrated keymat further comprises one or more lens-like pads provided on the keypads to make the legend or symbol on the keypads more visible.
摘要:
A small sized optical transmission unit suitable for non-simultaneous transmission and reception comprising a transmitter and a receiver operating in the optical wavelenght range is described. The optical unit includes an optical element. Furthermore, both the transmitter and the receiver are arranged to utilize the same optical element. In addition, the transmitter is positioned between the receiver and the optical element.”

A portable diagnostic apparatus is brought proximal to a device to be diagnosed. While the device to be diagnosed is operating, a radiofrequency interference signal emitted by the device is received at the portable apparatus and a data representation of it is stored. The data representation is submitted for matching to a diagnostic signal pattern stored in a database of predetermined signal patterns. From the matching is identified and output an indication of a fault in the device to be diagnosed. In one embodiment the submitting is to the database stored in the portable apparatus itself, and in another embodiment the submitting is outputting (data cable, wireless link) the stored data representation to a diagnostic computer such as a personal computer, a peer device, or a remote diagnostic center. The RF interference signal may be one stream and the portable apparatus receives at least a second stream and both streams are used for the matching.

Altimeters correct themselves by analyzing pressure data to identify underlying climatic changes and modify sensed pressures accordingly to provide corrected altitude values. The detected underlying climatic changes are used to provide a barometer function independent of altitude changes. Air pressure measured at a plurality of times is stored to provide historical pressure data. A reference pressure is modified in dependence on historical data to produce a modified reference pressure. An altitude value is obtained from the current air pressure value and the modified reference pressure and stored.

摘要:
A method and system for preventing unintended touch pad input resulting from accidental touching of a touch pad device in an electronic device. A user can execute one or more touch pad functions by touching the touch pad device. The electronic device includes a key lock function to put the electronic device in a locked state such that only a limited number of selected input functions are available when the electronic device is in the locked state. When touch pad device is touched, a software program is used to determine whether the electronic device is the locked state and whether the touch function is one of the selected input functions in order to carry out or to block the touch pad function.

The invention relates to a mobile radio-frequency enabled device. In order to enable a lightning detection by means of such a device, it comprises an electromagnetic interferences detection component detecting electromagnetic interferences in at least one radio-frequency channel, which at least one radio-frequency channel is usable by the mobile radio-frequency enabled device for a communication link. The device further comprises a processing component adapted to determine whether a lightning stroke can be assumed to have occurred in the vicinity of the mobile radio-frequency enabled device due to an electromagnetic interference detected by said electromagnetic interferences detection component. The invention relates equally to a corresponding system, to a corresponding method and to a corresponding software program product.
摘要:
Mechanical design considerations for the antenna and speaker functionalities in a mobile communication device are combined in the construction to reduce the physical size of the device. The antenna and speaker are carried in a common chamber which enhances bass-tone production of the speaker while maintaining antenna functional design consideration.
