A method for estimating load weights for a work vehicle including a boom pivotably coupled to the chassis of the work vehicle at a boom joint and an implement pivotably coupled to the boom at an implement joint may include receiving an input indicative of a tilt force associated with a tilt cylinder configured to pivot the implement about the implement joint, and an input indicative of a lift force associated with a lift cylinder configured to pivot the boom about the boom joint. The method may further include determining a torque about the implement joint caused by the load based on the tilt force and determining a torque about the boom joint caused by the load based on the lift and tilt forces. Additionally, the method may include estimating a weight of the load based on the torques about the boom and implement joints.

An occupant feature detection method and system, and a computer-readable medium, where the method includes: inflating a seat cushion airbag (10) with a gas of a first predetermined volume, and measuring a reference pressure formed by the gas of the first predetermined volume when no occupant is seated; measuring a first pressure formed by the gas of the first predetermined volume after an occupant is seated; and obtaining a first weight based on a difference between the reference pressure and the first pressure, and using the first weight as a reference weight of the occupant. The seat cushion airbag (10) disposed in the vehicle seat is used to calculate the weight of the occupant and determine a sitting position of the occupant based on the difference between the pressure in the seat cushion airbag (10) obtained when no occupant is seated and the pressure in the seat cushion airbag obtained when the occupant is seated. Therefore, a feature of the occupant may be identified without additionally providing a pressure sensor, so that a targeted protection strategy is set for each occupant.

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.

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.
