  • Patent number: 7755321
    Abstract: The present invention relates to a method for battery removal detection in a portable communication device and also to a portable communication device comprising a detection circuit. During start-up of the portable communication device the detection circuit is powered on and a first input of the detection circuit is set to a first logical level and a second input of the detection circuit is set to a second logical level. An output from the detection circuit is fed to a third input of the detection circuit and a new output value for the detection circuit is generated based on the first, second and third input and the new value of the output is stored in a memory means.

    Abstract: The present invention relates to a method for battery removal detection in a portable communication device and also to a portable communication device comprising a detection circuit (2). During start-up of the portable communication device the detection circuit (2) is powered on and a first input (A) of the detection circuit (2) is set to a first logical level and a second input (B) of the detection circuit (2) is set to a second logical level. An output (q) from the detection circuit (2) is fed to a third input (Q) of the detection circuit (2) and a new output value (q) for the detection circuit (2) is generated based on the first (A), second (B) and third input (Q) and the new value of the output (q) is stored in a memory means.

  • Publication number: 20090177462
    Abstract: Wireless terminals, language translation servers, and methods for translating speech between languages are disclosed. A wireless communication terminal can include a speaker, a wireless transceiver, and a controller circuit. The controller circuit is configured to operate differently in a language translation mode than when operating in a non-language translation mode. When operating in the language translation mode, the controller circuit transmits a speech signal containing speech in a first spoken language via the transceiver to a language translation server, it receives from the language translation server a translated speech signal in a second spoken language which is different from the first spoken language, and it plays the translated speech signal through the speaker.
