Efficient weight estimation and stabilization
This disclosure is directed to item-identifying carts that may be utilized by users to automatically identify items that the users place in their carts. In order to identify the items placed into or removed from the cart, the cart may analyze image data, as well as weight data indicating a current weight estimation of a basket of the cart. The cart may include a weight sensor that generates a signal comprising a series of weight measurements of the basket of the cart. The cart may use an algorithm that calculates different mean values of different window sizes of the weight measurements of this signal and, thereafter, may calculate an average of these mean values. This average may be stored as the current weight estimation of the basket.
ON-BOARD VEHICLE SCALES
The present invention provides methods and systems for determining the weight of a vehicle. Exemplary methods include the steps of: determining with one or more on-board sensors, a sensor output voltage; providing the sensor output voltage information to a processing unit to determine the weight of the vehicle; and displaying the weight of the vehicle on a visual display unit
Systems and methods for scale calibration
Systems and methods for scale calibration. One example embodiment provides a system for calibrating a scale. The system may generally include an actuator for applying force to a platform of the medical scale, and an electronic processor communicatively coupled to the actuator. The electronic processor may be configured to control an actuator to apply, for a first interval, a first applied force having a first value greater than a target force value, and control the actuator to apply, for a second interval, a second applied force having a second value substantially equal to the target force value.
Neonatal care system with weight measurement
A neonatal care system includes a platform for supporting an infant, at least one load cell configured to sense a weight of the infant supported on the platform, and an inclinometer configured to measure an angle of the platform. A controller is configured to determine an infant weight based on the sensed weight and the measured angle of the platform.

Load cell assembly including cavities to buffer horizontal shear forces
Disclosed is a load cell having a frame that includes a first and a second mounting surface. Each mounting surface is arranged on a common horizontal plane symmetrically about a central vertical axis. First and second lateral surfaces are arranged perpendicular to the first and second mounting surfaces. One or more mounting fixtures are located on the load cell at the first and second mounting surfaces and configured to attach to a support structure or a loading fixture. One or more force sensors are arranged symmetrically about the central vertical axis. One or more cavities extend the width of the frame and are arranged between a mounting fixture and the force sensors to buffer horizontal shear forces.

Load cell for a scale with a switching device for changing the state of calibration data write protection
The present invention relates to a load cell for a scale having a monolithically configured measurement body that has a force reception section, a force introduction section, and a joint section arranged between the force reception section and the force introduction section, having at least one strain gauge arranged at the upper side on the joint section for detecting a stretching deformation of the measurement body, and having electronics that are arranged at the force reception side, that are at least partly arranged on a circuit board, and that have a memory in which calibration data of the load cell and/or a value for gravity are stored, wherein a hardware interface is provided via which the memory can be accessed and via which the calibration data stored in the memory and/or the value for gravity can be changed.
