The present disclosure provides an equipment and method for measuring weight of instilled liquid crystals, so as to improve the measurement accuracy and the measurement efficiency of the equipment for measuring weight of instilled liquid crystals. The equipment includes a tray having a plurality of holes arranged in a circle and a measuring cup arranged within each hole, a pair of scales arranged below the circle of the holes, and a driving device connected to the tray in a driving manner and configured to drive the tray to move up and down and drive the tray that has moved to a high position to rotate to a position where one measuring cup to be measured is in alignment with the pair of scales.

A method for filling bags with metered quantities of bulk products includes providing a first container and a second container having an assigned total volume. Each container is divided into two respective half-volumes, each half-volume being designed to feed product to a first station or a second station for filling bags, so that each container has a half-volume connected to the first station and a half-volume connected to the second station of the two stations. A first predefined metered quantity of product is provided inside the first container by dividing-up the metered quantity of product into two quantities equal to approximately half the metered quantity, each fed to a respective half-volume of the first container. A bag is conveyed to the first filling station. The bag is filled with the quantity of product of the first half volume of the first container.

A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

A medicine container configured to hold one or more different medications. The container may include an orientation sensor to determine the orientation of the container. The container may also include one or more additional sensors to detect other physical characteristics about the container and/or medicine. The orientation of the container in combination with the information from the one or more additional sensors is used to determine an accurate indication of an amount of the medicine within the container and thus usage information. The container also includes a wireless transmitter for transmitting the information regarding the medicine to a remote location.

A mass measuring apparatus includes a transferring and gripping device for removing an article from a seat of a movement device, holding the article in a measuring position, and then reinserting the article into the seat. The transferring and gripping device includes a gripping element for holding the article, an actuator for operating with an actuating signal on the gripping element to make the gripping element vibrate at a specific resonance frequency, a sensor for measuring a vibration response signal of the gripping element vibrating and supporting the article in the measuring position, a processing unit for receiving the vibration response signal and controlling the actuator to generate an actuating signal to make the gripping element vibrate at an operating resonance frequency, and then calculating a mass of the article by comparing the operating resonance frequency with the resonance frequency of the gripping element.

A method for detecting a state of a coffee bean grinder includes providing a supply voltage to a motor of a grinding apparatus, and monitoring with a motor stall detection sensor at least one operating parameter of the motor. The method further includes determining whether a motor stall has been detected based on monitoring the at least one operating parameter. The method also includes measuring using a weight sensor a weight of coffee grounds that have been ground by the grinding apparatus, and determining that no beans are present in a hopper that feeds coffee beans to the grinding apparatus when no motor stall has been detected and no change in weight has been detected at the weight sensor for a predetermined amount of time. A coffee bean grinder is also disclosed.

A loose material measuring and dispensing system including a container and dispenser. The tea container serves to store the tea leaves or grounds in a storage bin prior to activation of the system. Upon activation, the dispenser measures and loads a selected amount of tea into a hopper for dispensing, such as into a waiting cup or a tea infuser. The amount of tea may be selected based upon user operation of one of a number of quantity indicating/selection buttons provided in a user interface. The container is a sealed canister, such as a bag or jug, which is preferably impermeable to light. Furthermore, the dispenser is able to operate to load a desired amount of tea (e.g. by weight), specified by the user, into the hopper. Once the desired amount of tea is loaded into the hopper, the tea may be dispensed, such as into a waiting cup or infuser below.
