Abstract: Methods, apparatuses, and systems are provided for providing access to real time information. A method may include running an application on top of a virtual platform. The method may further include determining a real time. The real time may define a non-simulation time that is maintained independently of the virtual platform such that the real time is not affected by performance of the virtual platform or of the application running on top of the virtual platform. The method may additionally include providing the determined real time for access by the application. Corresponding apparatuses and systems are also provided.

Abstract: A system and method for aligning and testing a communication device during production speeds up the overall production testing and thus shortens the testing time. The system comprises a measuring unit, RF switch, power supply and test bed comprising several modular test places, and is synchronized to perform test procedures with a minimum amount of control information transfer between the device under test and the test system. This is achieved by using low level and real time control operations, and configuring the test hardware to be only a little bit better and a little bit faster than the device under test itself.

Abstract: A keypad arrangement is used for providing electrical information to an electronic device in response to a manual pressing action of a user. The keypad arrangement comprises a number of depressable keys (803, 907) within a certain keypad area. It comprises also an arrangement of essentially continuous conducting means (301, 302, 901, 902, 1401, 1402) next to the depressable keys. Connection creating means (801, 908) are associated with each depressable key for providing, as a response to the depression of a key, an electrical connection through said essentially continuous conducting means. The electrical characteristics of the created electrical connection uniquely identify the location of the depressed key in relation to said essentially continuous conducting means.

Abstract: A power boost system for a portable radiotelephone (10) employs a booster unit (52) to provide sufficient power for operation of the radiotelephone as a mobile unit in a cellular telephone system, and a junction box (54) which, in combination with a mechanical holder (56) allows for hands-free operation of the radiotelephone in the mobile telephone environment. The junction box is provided with a speaker (62) and a microphone (64) to facilitate the hands-free operation. The desired output power level for radiation from a vehicular antenna (72) is provided by a gain-controlled amplifier (80) in response to a pulse-width modulated command signal (48, 90) provided by a computer (12) within the radiotelephone. A memory (70) within the booster unit stores power level data for the higher levels of power to be used during transmission by the booster unit, the power level data being provided to the computer (12) in generating the power command signal.

Abstract: An illuminated keyboard in which the keys are operable in at least two different modes. Each key is provided with symbols or areas of color which denote the different modes. The symbols or areas are selectively illuminated depending upon which mode is selected. Thus, in one mode, one area of the keys will be illuminated, while in another mode, another area of the keys will be illuminated. Thus, only the symbols or areas of color on denoting a selected mode are differentially visibly distinguishable by the user, assisting the user to press the correct key, in any selected mode.

Abstract: A power booster (10) comprises a power amplifier (5) and is coupled to a portable radio telephone (20) which transmits an RF signal at one of a predetermined set of power levels. A first detector (6) generates an output signal C indicative of the power of the RF signal received by the booster. The signal C is used to generate a reference signal rf from a look up table (8) in which is stored a set of values corresponding with the respective power levels. The reference signal rf, which indicates the required power level, is applied to a power control circuit (7) which controls the gain of the amplifier (5) to maintain the power output substantially constant at the required power level as determined by the value of the reference signal rf.
