A thin weighing scale having a thickness of less than 25 mm, comprising a first rigid bottom plate, extending along a reference plane defined by a first direction and a second direction, a second rigid top plate, at least four load cells, interposed between the first and second rigid plates, a set of linkages comprising arms, some arms extend in the first direction and some other arms extend in the second direction, each arm having an elongated shape with a first end attached to the first rigid plate and a second end rigidly connected to the second rigid plate, whereby a movement is provided along a third direction, the set of linkages preventing relative movement between first and second rigid plates along the first and second direction.

Thin weighing scale with a sandwich structure

A method for determining the weight of an entity/item to be weighed on a weighing device (), the weighing device comprising at least a weight sensor and a control unit (), the method comprising the following steps: 

Method and system to quickly determine a weight

Electronic scale including four feet, four strain gauges, an electronic control unit and a display, where the gauges are combined in pairs in first and second Wheatstone bridge type circuits, where a first intermediate-point of the bridge is selectively connected via a switch to an intermediate voltage source and where the first and second outputs of the amplifiers are summed by the electronic control unit in order to deduce therefrom a weight for an object present on the device, with indication for the user of off-center condition on the scale. Weighing method implemented in such a scale.

Weighing device and method with off-center indication

Device for measuring the concentration of a predetermined gas, in particular CO2, comprising a cavity, a light source emitting light rays within a basic spectral range including visible and infrared, a detector configured to receive a portion of the light rays within a first predefined spectral range corresponding to high absorption of the predetermined gas, a photodiode configured to receive a portion of the light rays within a second predefined spectral range corresponding to low absorption of the predetermined gas, a control unit configured to calculate the concentration of the predetermined gas by comparing the radiant power received by the detector to the radiant power received by the photodiode.

CO2 concentration sensor

Radio paging receiver comprising a central unit associated with a memory containing a tree-structured database comprising a plurality of menu pages and text pages, each menu page including at least an entry capable of being selected to display on the screen another menu page or a text page. Each entry of each menu page comprises a data field capable of being displayed and a call code corresponding to another menu page or text page. Moreover, the central unit is designed for updating the stored menu pages on the basis of radio messages comprising a menu page identification code and at least one entry designed to appear in the menu page presenting said identification code.
