A weight measurement device comprises: a housing cover to receive weight of a measurement target; a plurality of load cells to support the housing cover and detect the weight; a housing base comprising, for each of the plurality of load cells, a recessed and projected shape part comprising: a recessed part open upward to at least partially contain each load cell and fix the load cell; and a projected part projected downward corresponding to the recessed part; and an adjustment leg which at least partially contains the recessed and projected shape part, and comprises an adjustment mechanism part for height position adjustment at a position opposed to a side part of the recessed and projected shape part.

A refrigerator appliance with sensing for load determination including a shelf and shelf support with a resilient member positioned so as to be compressed by the weight of food items placed on the shelf. Changes in pressure or flowrate of a fluid in the resilient member are used to detect changes in the weight of food items. The appliance can be configured to execute one or more events based on the detected changes.

An adjustment device for a splicing display screen includes: a housing including housing walls and an accommodating cavity, the housing walls including first, second, third and fourth housing walls; a piston member including a piston and a piston rod, wherein the piston is slidably connected in the accommodating cavity, a through hole is provided in the fourth housing wall, and the piston rod is slidably connected in the through hole; an elastic pressing portion in the first housing wall, serving as a part of the first housing wall; and a hydraulic sensor in the accommodating cavity. The accommodating cavity is filled with hydraulic fluid, an inner surface of the elastic pressing portion contacts the hydraulic fluid, and the piston member is configured to be driven by the hydraulic fluid to move in an extending direction of the through hole in response to a pressure applied on the elastic pressing portion.

A ball mount for measuring tongue weight of a trailer is disclosed. The ball mount can include a ball portion having a hitch ball configured to couple with a tongue of a trailer. The ball mount can also include a hitch portion for interfacing with a hitch receiver associated with a vehicle. In addition, the ball mount can include a load measurement device associated with the ball portion to determine a magnitude of a downward force on the hitch ball. The load measurement device can include a reservoir having a fluid and a piston disposed therein, and a pressure sensor in fluid communication with the reservoir. The hitch ball can be configured to exert a force on the piston, thereby affecting a pressure of the fluid in response to the downward force on the hitch ball.

A weight scale system is for measuring the weight of an object, which includes a bed section, a vertical separator actuator and a controller. The bed section includes a lower-platform, an upper-platform and weight sensor assemblies located on the lower-platform, each includes at least one weight sensor. The bed section further includes at least one vertical-separator. The vertical-separator actuator is coupled with the vertical-separator and with the controller. The controller is coupled with the weight sensors. The controller directs the vertical-separator actuator to operate the bed section in at least two modes, a referencing mode in which the vertical-separator detaches the upper-platform from the weight sensor assemblies, thereby enabling referencing the weight sensors, and a weighing mode, in which the vertical separator re-attaches the upper-platform with the weight sensor assemblies, such that the weight associated with the upper-platform is fully applied on the weight sensors.

An occupant classification system comprises a capacitive sensor configured to measure capacitance. The capacitive sensor is at least partially arranged between a seat frame and at least one of a seat cover and a seat cushion of a seat. A sensor is configured to measure at least one of weight and pressure on the seat. The sensor is at least partially arranged between a vehicle structure and a component of the seat. A controller is configured to generate an occupant classification based on the measured capacitance and the at least one of the measured weight and the measured pressure on the seat.
