A weight measuring hitch ball assembly is described. The assembly can include a hitch ball having a ball and a lower portion. The assembly can also include a body portion defining a hitch ball opening that slidably receives the lower portion of the hitch ball. The assembly can further include a load measurement device operably associated with the body portion and the hitch ball to determine a magnitude of a force acting on the hitch ball. Additionally, the assembly can include a retention coupling operable with the hitch ball and the body portion to secure the hitch ball to the body portion. The retention coupling can have a retention protrusion and a retention wall defining at least a portion of a retention opening operable to receive at least a portion of the retention protrusion therein. With the retention protrusion extending into the retention opening, the retention wall can provide a mechanical barrier to the retention protrusion that prevents removal of the hitch ball from the hitch ball opening. The retention opening can be configured to facilitate slidable movement of the hitch ball within the hitch ball opening sufficient to determine the magnitude of the force acting on the hitch ball.

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.

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.

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.

An example of an apparatus is provided. The apparatus includes a container to store a powder. The apparatus includes a flow generator to move a gas to the container. The flow generator is to move the gas at a first velocity and a second velocity, the first velocity to fluidize the powder in a fluidized state, and the second velocity to pass through stationary powder in a powder pack. The apparatus includes pressure sensors to measure pressures in the container. The apparatus includes a measurement engine in communication with the pressure sensors, wherein the measurement engine is to calculate a mass of the powder based on a fluidized pressure differential and based on a pack pressure differential.

A ball assembly for attachment to a ball mount is described. The ball assembly can include a ball post that is securable to a ball mount. A hitch ball is slidably coupled to the ball post at a ball end of the ball post. A load gauge is disposed at the gauge end of the ball post. A load transfer element is operably associated with both the hitch ball and the load gauge so as to cause a load measurement to display on the load gauge based upon a load applied to the hitch ball.

The present invention relates to a farming/veterinary device, system, and method for sensing force to analyze the stance of an animal or human to determine lameness and total weight monitoring. The invention is directed to an air cushion device for determining lameness and total weight management for animals with an air cushion for each animal leg which will enable the system to determine the force exerted on each air cushion. Optimally, the air cushion device is waterproof. The system is directed to incorporating the air cushion device with an air supply system and sensor system to automatically determine lameness and total weight in animals. The method is directed to a procedure for using the air cushion system to determine lameness and total weight in animals. Because implementations of the device are waterproof, it is suitable for use in any type of wet or dirty environment. Further, due to making the determinations while the animal is standing still, the device is capable of on-site installation in areas of the farm such as milking stalls, cattle chutes, and other small areas in which the animal is used to being.

A weight scale system for measuring the weight of an object 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 further 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 the that the weight associated with the upper-platform is fully applied on the weight sensors.
