摘要:
Electronic weighing scales (1) comprising four feet, four strain gauges, an electronic control unit (4) and a display (5), the gauges being combined in pairs in first and second Wheatstone bridges (31, 32), a first intermediate point (51) of the bridge being selectively connected via a switch (T1) to an intermediate voltage source (Vi), the first and second outputs (73, 74) of the amplifiers being summed by the electronic control unit in order to deduce a weight of an object present on the device therefrom, an indication being given of the off-centeredness of the user on the weighing scales. Weighing method employing such a weighing scales.
摘要:
A weight sensor comprising a weighing platform and a load cell coupled to the platform to sense a weight applied to the platform, the load cell comprising a deformable plate with one or more strain gauges arranged to provide an electrical signal representing the weight applied to the platform, and a base supporting the load cell, wherein the deformable plate is movably mounted to the base at only three contact points, the contact points allowing lateral movement of the plate relative to the base when the plate deforms in response to a weight applied to the platform. The weight sensor makes it possible to independently monitor the weight and weight shifting of two people sharing the same bed. The weight sensor is selfcentring when a load is applied off-centre to the platform, which is particularly beneficial when such a weight sensor is used underneath a bed, e.g. under a bed leg or other support member which may not be aligned centrally over the weight sensor. Beneficially the sensor is not unduly affected by minor misalignment of the leg of a bed relative to the load cell.
摘要:
A high-speed out-of-band signalling technique for transferring information such as station status information between stations in a communication network, typically a local-area network, involves sequentially generating a plurality of n-bit sequence segments, where n is at least 3. Each bit is either a first binary value or a second binary value. Each sequence segment is coded with one of a plurality of different n-bit code groups divided into a first code group and a set of second code groups. The n bits in the first code group are all the first binary value, e.g., all "1s". None of the second code groups contain a pair of non-contiguous bits of the second binary value, e.g., none of the second code groups contains two "Os" separated by at least one other bit. The sequence segments are outputted in the order that they were generated to produce a special bit sequence which carries the desired information. The station status information typically includes configuration capability, flow control parameters, and integrity control parameters.

Bei einem Verfahren zur Bestimmung von immanenten Kräften einer in Tragarmen (7-10) eines Rollenträgers aufgeachsten Vorratsrolle (14) sind die Tragarme (7-10) mit einer Anzahl von Meßwertaufnehmern (24,25,61,62,66,67,69,76,77,78) versehen. Die ermittelten Ergebnisse werden einem Rechner zugeleitet welcher nachfolgend nach Eingabe der Breite sowie des spezifischen Gewichtes der Materialbahn die Länge der Materialbahn ermittelt. Zur Durchführung des Verfahrens ist eine Einrichtung vorgesehen.

A scale apparatus (170) includes a load cell support (172) and a load cell (30) having a base (36) and a contact portion (38) extending upwardly away from base (36). Load cell (30) is coupled to load cell support (172) and support (172) is coupled to a conveyor frame (12, 118 or 198) to suspend load cell (30) below a conveyor belt (24). The apparatus (170) further includes an idler support (174) for supporting idler assembly (14). Idler support (174) is coupled to contact portion (38) of load cell (30). Idler support (174) applies a downwardly directed force to contact portion (38) of load cell (30) to bend base (36) of load cell (30) in response to material moving on conveyor belt (24) over idler support (174) to change an output signal generated by load cell (30) in proportion to the weight of the material.
