Abstract: Provided herein are various embodiments of an improved device for accurate measurement along a desired axis that is tolerant to off axis movement and other environmental factors. The measurement relies on a conversion from linear displacement of a tensile element in a pulley system which is monitored by a low power rotational encoder. The orientation and mechanical architecture of the device is set to reduce the impact of off-axis movement or forces on the measurement of interest. A computing unit determines the distance measurement by determining the state of rotation in the system in the context of the system's specific design, without the need to constantly monitor the sensor.

Abstract: According to one aspect, this disclosure describes a novel indirect weight sensing device, systems, and related processes. In at least one embodiment, the present systems include one or more springs with known properties, at least one metal plate on which the springs are fastened and through which the container load is transferred from the container to the ground, a spring deformation sensor by which spring deformation is reckoned, a digital level by which general orientation of the upper plate is determined relative to the ground, a computing unit to collect and process data from the spring deformation sensor and digital level, and an antenna or other such hardware to wirelessly connect to another device and interface with the computing unit.
