Abstract: Techniques for frequency-hopping sequence-generation are described herein. In one example, a sequence of pseudo random numbers may be used to generate a scrambling sequence. The scrambling sequence may be used to map an unscrambled sequence of channels into a scrambled sequence of channels. Channel-repeats may be detected in the scrambled sequence of channels and resolved. Channel whitening may be performed to reduce channel overuse resulting from the channel-repeat resolutions. The scrambled sequence of channels may be provided to a radio to enable the radio to tune to the channels indicated by the scrambled sequence of channels.

Abstract: A fluid meter includes a totaliser having an electronic card that communicates with a remote meter reading system. The electronic card may be contained in a metal housing covered in a leakproof manner by an upper transparent panel. The totaliser may be covered by a cover which retains the upper transparent panel in a leakproof manner. The cover may be covered by a cap made from plastic material. The upper transparent panel may be made from glass and the upper transparent panel and the cover may each include an orifice to allow communication between the electronic card and antenna disposed between the cover and the cap.

Abstract: Meters are described. In one example, a meter includes a totalizer including an electronic circuit and a metering screen, a cap at least partially covering the totalizer, the cap including a window to facilitate viewing of data of the metering screen, and a screen cover mounted on the cap and movable between an open position and a closed position in order to cover the metering screen. In such an arrangement the electronic circuit includes a device for detection of the open position or the closed position of the screen cover, and the detection of the open position or the closed position controls scrolling of data of the metering screen.

Abstract: The invention relates to a bidirectional wireless transmission system for serial format data signals between a “master” electronic device (3) and a “slave” energy meter (2) including a microcontroller (20) having a serial input port (RX). According to the invention, the serial format data signals are exchanged at short range via bidirectional electromagnetic coupling means (4) outputting a pulse on each rising or falling front in said serial format data signals. To transmit data signals from the “master” device (3) to the “slave” meter (2), the pulses at the output of the electromagnetic coupling means (4) are delivered to said serial input port (RX).

Abstract: The invention relates to a fluid meter, in particular a water meter, comprising a counter presenting an upper electronic card including a meter screen, the counter being covered by a cover including a window for viewing said screen, and said cover itself being covered by a cap presenting an external window for viewing said screen, a screen cover being mounted on said cap to cover and protect said screen and said external window. According to the invention, said screen-cover is provided with at least one pivot pin placed on a bearing carried by said cap, and said cap is provided with at least one orifice for passing a locking element for locking said pin on said bearing, the locking element being carried by said cover.

Abstract: The invention relates to a fluid meter, in particular for water, comprising a totaliser having an electronic card including a remote meter reading system using radio waves and contained in a metal housing covered in a leakproof manner by an upper transparent panel, this totaliser being covered by a cover which retains the said upper transparent panel in a leakproof manner and the said cover being covered by a cap made from plastic material. According to the invention the said upper transparent panel is made from glass and the said upper transparent panel and the said cover include an orifice in which is disposed a watertight arrangement for transmission of radio waves from the said electronic card towards an antenna disposed between the said cover and the said cap.

Abstract: The invention proposes a system for assisting deployment of a fixed remote meter reading network, in which system an access point is to recover measurement data from meters (1) by radio, said data being transmitted via a radio communication module (2) associated with each meter and being relayed to the access point via at least one intermediate collector. The system enables an installer to be equipped with a portable device enabling in situ validation of future positions for intermediate collectors.
