Abstract: An RF telemetry receiver circuit for active implantable medical devices. The baseband binary signal (Db) is doubly modulated by a low frequency carrier (Fm) and by a high frequency carrier (Fc). The receiver circuit is a semi-passive non heterodyne circuit, devoid of a local oscillator and mixer. It comprises an antenna (104), a passive bandpass filter (108) centered on the high-frequency carrier (Fc), a passive envelope detector (120-126) and a, digital demodulator (116). The envelope detector comprises a first diode circuit (120) of non-coherent detection, an active bandpass filter (122) centered on a frequency (2.Fm) twice the low frequency carrier and having a bandwidth (2.Db) twice the baseband bandwidth, and a second diode circuit (124) of non-coherent detection, outputting a baseband signal applied to the digital demodulation stage (116).

Abstract: A monitoring device, system and method is provided for in-home/on-premises monitoring of usage of utilities, such as electricity and other services. The monitoring device receives information from a smart metering system or transceiver, and displays current usage through an illuminated display, which displays a colour indicative of the current cost of consumption, and controls illumination of the display to scan illumination across the display at a traverse rate indicative of a rate of consumption or other metric, the scanning of a pattern of illumination across the display simulating movement or rotation in the display. The display therefore provides a consumer with immediate “at a glance” visual information on current usage. Optionally a digital display screen provides more detailed alphanumeric and graphical information, through a number of selectable display modes.

Abstract: A sensor head includes a sensor element whose measurement signal can be fed to a comparator. The comparator compares the measurement signal to a threshold value and forwards a binary output signal to a transmission circuit. The sensor head is provided with electric energy via a proprietary two-wire line. In addition, the output signal can be transmitted from the transmission circuit via the two-wire line to a higher-order control module that is located outside of the sensor head. At least two sensor heads of this type can be connected to the control module.
