  • Patent number: 10309823
    Abstract: 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 4, 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.

  • Patent number: 10024709
    Abstract: A method for determining the weight of an entity/item to be weighed on a weighing device (1), the weighing device comprising at least a weight sensor and a control unit (4), the method comprising the following steps: /a/ collecting weight raw samples (WSi) of the total weight sensed at the weight sensor(s), at a sampling frequency (F0), and converting each of the weight raw samples (WSi) into digitalized weight raw samples (DSi), /b/ entering sequentially each of the digitalized weight raw samples (DSi) into a Butterworth filter, the latter issuing filtered weight samples (FSi), /c/ defining a rolling window (RW) containing a parametrized number NS of latest filtered weight samples (FSi), /d1/ determining, in the rolling window, the minimum (MIN) and maximum (MAX) values of filtered weight samples, /d2/ comparing the value of MAX?MIN with regard to a parametrized Threshold (T), /e/ if MAX?MIN is greater than Threshold (T), repeat steps /a/ to /d2/, and as soon as MAX?MIN is less than Threshold (T), output a

  • Patent number: 9939309
    Abstract: 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.

  • Patent number: 9574995
    Abstract: 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.

  • Patent number: 6765475
    Abstract: 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.
