Abstract: A weighing device (1) has a load-bearing portion (10) that supports an object being weighed, a plurality of transition portions (20), and a separation portion (30). The transition portions are positioned on the separation portion, and the load-bearing portion is positioned on the transition portions, with the transition portions connected to the load-bearing portion and the separation portion. A plurality of weighing sensors (40) are provided at a bottom of the separation portion. A support portion (50) is below the weighing sensors to provide support therefor. The weighing device simplifies the loading condition of weighing sensors and isolates the horizontal mechanical deformation/distortion of the weighing load-bearing mechanism. It also reduces the influence of mechanical deformation/distortion, thereby improving the weighing performance and the effectiveness of the weighing device.

Abstract: A high-capacity weighing module has a top plate weldment (10), a bottom plate weldment (30) and a pressure-bearing assembly (20) that is between the top and bottom plate weldments. Motion between the respective top and bottom plate weldments is restricted. This structure aids in easy installation and replacement of a sensor, and integrates the functions of anti-overturning and 360° inspection, and bottom stop. This makes the weighing module much more convenient to install than a conventional high-capacity module, and has a better safety function. The weighing module has advantage in terms of a simplified product structure, reduced cost of manufacture and maintenance, uncomplicated installation procedure, and higher safety and protection.

Abstract: A force sensor has a first end portion (1), a second end portion (2), a parallel-guiding mechanism (3), a beam (4), and a strain gauge (5). The parallel-guiding mechanism (3) connects the first end portion (1) to the second end portion (2). A main beam (43) of the beam has a flexible wall (435) and a rigid wall (432). A first connecting part (41) connects the flexible wall to the first end portion, and a second connecting part (42) connects the rigid wall to the second end portion. The strain gauge (5) is fixed to the flexible wall (435). The force sensor can measure a relatively small force.

Abstract: A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.

Abstract: An optical structure has a cavity (1) with an opening provided at one end and a first through hole or first gap (21) provided at the end opposite the opening. The cavity is further provided internally with a beam splitter or a dichroic mirror (4). A first LED (31) emits light into the cavity through the first through hole or the first gap, which passes directly passing through the beam splitter or dichroic mirror and exits from the opening of the cavity A second LED (32) emits light into the cavity through a second through hole or second gap (22) in a side of the cavity, which is reflected by the beam splitter or dichroic mirror. It is then fused with the light emitted by the first LED. The light emitted by the respective LEDs have an identical optical path length to the beam splitter or the dichroic mirror.
