  • Wireless meter for real time measurements and method therefor
    Patent number: 7305327
    Abstract: A wireless metering device for real time measuring of at least one parameter has a probe for measuring the at least one parameter. The probe will wirelessly transmit real time measured values. A meter is wirelessly coupled to the probe. The meter is used for displaying the real time measured values.

  • Single button operating sound level meter and method therefor
    Patent number: 7270006
    Abstract: A sound level monitor device has a microphone. A sound level measurement circuit is coupled to the microphone. The sound level measurement circuit takes sound signals monitored by the microphone and converts the sound signals to digital signals. A display is coupled to the sound level measurement circuit. The display will show the different measurement signal values. A single control button is coupled to the sound level measurement circuit. Pressing the control button a first time activates the sound level measurement circuit so a current measurement signal value is shown on the display. Pressing the single control button a second time causes a highest recorded measurement signal value, since the sound level measuring device has been presently activated, to be shown on the display. The highest recorded measurement signal value remains on the display until a higher recorded measurement signal is monitored.
