The present invention relates to a luggage scale device. A housing of the device can be attached to a wall via a fastener, wherein a weighing member can then be extended perpendicular to the housing. The strain gauge load cell is positioned on the member and allows luggage to be weighed via placing a strap of the luggage on the member such that the device suspends the luggage above the ground. The weight of the luggage is then displayed via a display on the housing.

A load cell includes a bearing element configured for a hoist that includes a hook, a suspension with an orifice that receives a shaft of the hook, a nut, and housing. The bearing element, preferably a ring, contacts the suspension, and has an orifice that receives the shaft therethrough with the nut secured to the shaft proximate to the bearing element. Strain gauges are mounted on the ring side wall being equally spaced. A second suspension orifice concentric with the first orifice receives the ring with strain gauges therein. For improved accuracy, a thrust roller bearing and two thrust washers are positioned on sides of the ring, all of which are preferably positioned in a cup member that is received in the second orifice. A clearance fit is provided with respect to each of protruding upper and lower overhanging cylindrical ring lips and the cup to protect the gauges.

An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

A load detection mechanism for detecting a load of an object includes a first member connected to a fixed structure; a second member for suspending an object; a pin (CP1, CP2) configured to cause the second member to be suspended from the first member by continuously penetrating the first member and the second member; a plurality of strain gauges (SG1 to SG8) attached to the pin; and a circuit substrate disposed above the second member. A connection circuit (CC) forming a bridge circuit by connecting the plurality of strain gauges and an amplification circuit (AC) configured to amplify output from the bridge circuit are formed on the circuit substrate.

Methods and systems for estimating an axle load of a vehicle are described. In one example, a method is disclosed wherein axle load is estimated in response to an angle between two components of an axle. The angle may change as weight is added to or removed from the axle such that axle load may be determined as a function of the angle.
