A device and a method for testing tablets are disclosed. The device for testing tablets includes a test chamber, which has a crusher jaw and, lying opposite the latter, a counter-jaw. The device has a movable sheet metal strip, which is designed to position a tablet for testing. The longitudinal axis of the movable sheet metal strip is at an angle of less than 90? to the longitudinal axis of the direction of movement of the crusher jaw, and the direction of movement of the sheet metal strip corresponds to the longitudinal axis of the sheet metal strip.

The load-bearing capacity of cylindrical shells of a composite fiber material that are at risk of buckling is determined by deriving improved reduction factors for analytical calculation of the design load. A load distribution head applies an axially acting force to a cylinder shell. A dent actuator dents the surface of the cylinder shell in a predetermined dent direction with a predetermined dent depth. A dent force is determined when a steadily increasing, axially acting force is applied to the cylinder shell by the load distribution head until a complete failure of the cylinder shell is detected. An analysis unit determines a dent depth from a data memory at which a dent force at a complete failure of the cylinder shell is at a maximum compared to dent forces of other dent depths.

The invention relates generally to a mechanical device that efficiently measures physical parameters such as compression strength, elasticity, firmness, deformation resistance and the like, on one or a plurality of compressible test objects including fruits, nuts and vegetables, and which operates in a semi-automatic fashion using an indexable turntable linked to one or a plurality of measuring stations capable of independently measuring said physical parameters, employing a controlled gravity assisted test assembly as a means for applying a steady, continuous gravitational force to said compressible test objects while recording said parameters by means of one or a plurality of sensor elements associated with said measuring stations.

The present disclosure relates to a device for detecting a liquid crystal module and a method for detecting the quantity of liquid crystal. The method includes a cover for fixedly accommodating the liquid crystal module. An accommodation space for accommodating collision units is formed between the liquid crystal module and the cover, the collision units being connected to the top wall of the cover through elastic members. The collision units are spaced from the liquid crystal module in a certain distance in a static status, and collide with a panel of the liquid crystal module through vibration of the cover in the vertical direction during detection. The device for detecting a liquid crystal module improves the detection efficiency.

The present invention relates to a jig for evaluating a buffer pad. The jig includes a first plate configured to be positioned on one surface of the buffer pad and configured to press the buffer pad; a second plate configured to be positioned on another surface of the buffer pad and configured to press the buffer pad from the other surface; and a magnet member configured to be positioned between the first plate and the second plate. A recessed portion, which is recessed to allow the magnet member to be disposed, is defined at an edge of at least one of the first plate and the second plate.
