System for detecting noise in weight data

Noise that is present in the output of a weight sensor can lead to erroneous weight data. A moveable device, such as a tote, may be used by a customer while shopping in a facility. This tote can include one or more weight sensors that are used to determine the weight of items added to or removed from the tote. However, noise can affect the output of the weight sensors, where such noise is attributed to movement or vibration of the tote. Data from a vibration sensor or a motion sensor coupled to the tote can be analyzed to determine noise that is common to weight data and vibration data or motion data associated with the tote. This common noise can then be removed or attenuated from the weight signals to determine de-noised and valid weight data for the tote.

Shelf bracket assembly

A shelf bracket assembly is mounted on a vertically disposed shelf upright, and has: at least one weighing device; an anchoring device; and a cantilever for supporting a shelf panel. In a condition where the shelf bracket assembly is mounted on the shelf upright, the cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed metal plate. In a Cartesian coordinate system, an extent of the cantilever in a horizontal plane defines a Y-direction, a vertical direction defines a Z-direction, and a direction perpendicular to the Y-direction and the Z-direction defines an X-direction. The at least one weighing device includes: a force-introduction section; a linkage section; and a force-supporting section. The linkage section comprises two weighing plates extending horizontally and parallel to each other. The force-supporting section and the force-introduction section are at least partially formed of vertically extending metal plates.

SYSTEM FOR AUTOMATED MEASUREMENT OF FLUID OUTPUT
20170307423 · 2017-10-26 ·

A system for automatically measuring and recording when fluid such as urine is introduced to a fluid collection container is provided. The system includes a measuring device that includes a load cell in communication with other various electronic components. The load cell is attached on one end to a fixed object like a hospital bed. At its other end, it is attached to a fluid collection container such as a urine collection bag. When fluid is introduced into the container, the load cell detects a stress change. A strain gauge (or gauges) on the load cell detects a resistance change and reads the change as a voltage change. That voltage change is amplified and digitized and converted to a weight, volume, and flow rate, before being transmitted to a recordkeeping system like electronic medical records. The system thus provides for real time measurement of fluid output collected in the container.
