  • Publication number: 20140314082
    Abstract: An apparatus comprises at least one processor and at least one memory including computer code. The at least one memory and the computer code are configured to with the at least one processor cause the apparatus to at least perform receiving a first message from a first port, the first message for transmission in a communications network. The first message comprises at least one destination address. The apparatus is also configured to perform determining whether the first message is deliverable and generating a second message comprising the at least one destination address for each undeliverable address; and transmitting the second message.

  • Publication number: 20100259285
    Abstract: The invention relates to an electronic circuit and a method capable of providing feedback in the electronic circuit, such that the effect of leakage currents in the circuit are minimised. The method includes the steps of storing an analogue input signal using an analogue storage device, converting the stored analogue input signal into a digital signal and storing the digital signal, converting the stored digital signal into an analogue feedback signal, and providing feedback in the electronic circuit using the analogue feedback signal.

  • Publication number: 20080174550
    Abstract: The invention relates to a motion-input device for a computing device, comprising a housing; a three-axis acceleration sensor arranged in said housing for outputting inertia signals related to the orientation and the movement of the motion-input device with a three-axis compass arranged in said housing, for outputting magnetic field signals related to the magnetic field orientation of the motion-input device, wherein said motion-input device is provided with a transfer component for transferring said magnetic field signals and said inertia signals to said computing device.

  • Patent number: 7216053
    Abstract: An energy-efficient acceleration measurement system is presented. The system includes an accelerometer, responsive to acceleration of the system, for providing an accelerometer output signal having a magnitude indicative of at least one component of the acceleration. A motion detector is responsive to the accelerometer output signal, and provides a processor interrupt signal, but only if the magnitude of acceleration reaches a threshold. The processor, responsive to the processor interrupt signal, measures the acceleration with higher accuracy than the motion detector is capable of, but in a way that consumes more power than was needed by the motion detector.

  • Publication number: 20040266480
    Abstract: A system, apparatus and method for incorporating sensor functionality into mobile communication devices having a host process and employing at least one memory, such as a removable memory card. Access to the removable memory card by the host process is facilitated using a digital interface, and storing sensor data from one or more sensor modules into a local memory. The host process of the mobile communication device is coupled to the local memory via the digital interface which is used by the host process to access the removable memory card. The sensor data may then be accessed from the local memory by the host process via the digital interface.

  • Publication number: 20040181703
    Abstract: The invention relates to an electronic device comprising means for controlling operation modes, one or more subunits for which, in terms of power consumption, at least two operation modes are determinable, one of the modes being an active mode and one being a sleep mode, in which sleep mode power consumption is smaller than that in the active mode.
