摘要： A device coupled to a communication terminal allows an emergency sequence to be triggered. During the emergency sequence, the communication terminal outputs a signal, so that, by way of example, a voice link is set up to a prescribed telephone number. The external triggering apparatus is in the form of a memory card, for example, which has a triggering grip and is coupled to the communication terminal by means of a card reading apparatus.

摘要： To maintain a receiving sub-system in a multiple standard communication device fully operational according to all operation modes of a second transmitting sub-system of the multiple communication device it is proposed that a multiple standard communication device of the type with parallel operation comprises a first subunit at least receiving input signals at a predetermined input level, and a second subunit at least transmitting output signals at a specific time, frequency and output level such that the output level is very large compared to the input level of the first subunit. According to the present invention the operation mode of the first subunit is modified when the second subunit is transmitting output signals.

摘要： The invention relates to a device and a method for temperature compensation via the determination of cut-angles of a master and a slave crystal (mc, sc) employed in a master and slave oscillator (m, s). When the master and the slave oscillator (m, s) have been tuned to their center frequencies (fc_m, fc_s), then the temperature characteristic of the slave oscillator (s) is actively detuned with respect to the temperature characteristic of the master oscillator (m). In a detuned state a frequency ratio parameter (n_s) of the slave to the master output frequency (f_s/f_m) is determined and the cut-angle is determined by using this parameter (n_s) to read out the cut-angle dependent on the temperature (T) from a memory (MEM). The invention also relates to a temperature compensation device and method where two crystals of different cut-angles are used and a frequency ratio parameter is determined to determine the identity/symmetry or difference of the cut-angles. Particular useful applications of the invention are in dual-mode mobile telephones which require the use of at least two oscillators with different resonant frequencies.

摘要： The invention compensates for any interference from a mobile communication unit to a positioning receiver unit in a multiple standard communication device with mobile communication and localization functionality. A first sub-unit receives input signals at a predetermined input level. A second sub-unit transmits output signals at an output level that is large compared to the input level of the first sub-unit. A branch-off unit branches off a part of the output signal before the antenna of the second sub-unit. An interference suppression unit receives the branch-off part of the output signal and derives an interference compensation signal therefrom through attenuation and subsequent phase shifting. The interference compensation signal is supplied to a superposition unit that also receives the input signal of the first sub-unit.

摘要： The invention relates to an electrical component (CO) as well as a device (DEV) comprising such an electrical component (CO) and an electric circuit module (MO). A ground plane (4) of the component (CO) and a ground plane (2) of the circuit module (MO) are brought into contact via projections (4″) provided on the ground plane (4) of the component (CO) and/or on the ground plane of the circuit module (MO). The provision of the projections (4″) and the recesses (4′) therebetween provide heat sinks between the projections (4″) when they are soldered to the ground plane (2) of the circuit module (MO). Through-holes (8′) and additional non-ground conductors (2′) can be provided between pads (14) of the ground plane (2) of the circuit module (MO) allowing an efficient use of the available space. The invention is particularly useful when a patch antenna needing a large ground plane is connected to a multilayer circuit board. Another embodiment of the invention comprises a plurality of spacer elements which are arranged between the ground planes (2, 4) of the circuit module (MO) and of the component (CO), such that the ground planes (2, 4) can be kept flat. This allows a design of the configuration of the ground plane of the circuit module (MO) independently from a configuration of the component (CO).
