The present disclosure pertains to a wireless scale, interface and release system for recreational and commercial weighing of items of any kind in a uniform and secure manner, furthermore designed for use on any form of bodies of water, tributaries, ocean, vehicle or land. The present disclosure comprises, scale inside of a waterproof housing, and a user interface to prompt the user through the weighing and release of the item or animal.

An elevator car load measurement system for determining a load of an elevator car includes a plurality of at least two force sensors that are daisy-chained and connected to a controller for determining the load. Each force sensor measures a force exerted by the elevator car on the respective force sensor and generates a frequency signal with a square-wave form, wherein the frequency signal is proportional to the respective measured force. At least one of the force sensors adds a first frequency signal received from the previous force sensor along the daisy chain a second frequency signal generated by the at least one force sensor to generate a frequency sum signal, the last of the force sensors in the daisy chain forwards the frequency sum signal to the controller.

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 portable weighing scale for weighing a bale of crop includes a support frame configured to be transported on ground. A powered lift is operatively coupled to the support frame and configured to lift the bale of crop off the ground. A weight measurement system is operatively coupled to the support frame and configured to measure the weight or mass of the bale of crop when the bale of crop is lifted off the ground by the power lift.
