摘要： A weighing system includes a support, a load cell mounted to the support, and a part platform suspended from the load cell to receive a part to be weighed. The load cell is operable to generate thousands of weight values for the part per second over a period of less than twenty seconds. The load cell is operable to output a weight of the part by averaging the weight values over the period of less than twenty seconds. A method of weighing the part suspended from the load cell is also disclosed.

摘要： A weighing apparatus includes a load cell assembly with an elongated load cell body including a first three dimensional coordinate orientation defined by a first X-axis, a first Y-axis and a first Z-axis. An accelerometer unit is operatively connected to the elongated load cell body and having a second three-dimensional coordinate orientation defined by a second X-axis, a second Y-axis and a second Z-axis. A memory unit is mounted on the elongated load cell body, the memory unit storing data for aligning the second three-dimensional coordinate orientation of the accelerometer unit with the first three-dimensional coordinate orientation of the elongated load cell body.

摘要： Provided is a scaling and monitoring system for remotely weighing, monitoring, and measuring volumes of rubber buffings (also referred to in text as “shavings” or “dust”) produced by commercial tire retreading plants and other materials. The method utilizes a custom scale system installed underneath a shipping container or a semi van trailer, container, or other collection and storage unit or area. The custom scale system feeds weight data to a PLC and VPN/gateway-based control panel which processes and relays information to the Internet, thus allowing all accessible and recorded data to be remotely collected and viewed for the purpose of optimizing rubber dust collection and processing and minimizing overhead costs associated with such processes.

摘要： Disposition of a wrong liquid for analysis or a liquid for analysis connected to a wrong pipe is detected as abnormal use. A liquid-for-analysis monitor includes: a weighing scale that weighs a container that contains a liquid as a liquid for analysis that needs to be used in analysis; a density storing part that stores a density ρ of the liquid for analysis; and a liquid-for-analysis determining part configured to obtain a variation ΔM between a weight of the container weighed by the weighing scale before a decreasing operation that decreases the liquid for analysis and a weight of the container weighed by the weighing scale after the decreasing operation, and determine whether the liquid for analysis has been normally used in the decreasing operation or not, based on the obtained variation ΔM, a volume V of the decrease in the liquid in the container in the decreasing operation, and the density ρ of the liquid for analysis stored in the density storing part.

摘要： The present invention is directed to a trolley case with a charging device, which comprises a case body, a pull rod frame mounted on the case body and a traveling wheel mechanism installed at the bottom of the case body; the pull rod frame is provided with a telescopic pull rod used for dragging the case body, the pull rod frame is provided with a charger accommodating cavity positioned in the middle of the pull rod and used for placing a charging device, the upper part of the charger accommodating cavity is provided with an opening, sliding chutes are arranged on both sides of the opening, and a sliding cover used to cover or open the opening is slidably arranged in the sliding chutes. The independent storage position of the external charging device of the present invention is convenient for taking the charging device at any time, and the setting of the sliding cover prevents the charging device from falling out easily; the spring can eject the charging device and can make the charger accommodating cavity adapted to charging devices of various specifications, the specifications of the charging device are proportional to the compression deformation of the spring, the larger the charging device is, the more greatly the spring is compressed, and the smaller the charging device is, the more slightly the spring is compressed.

摘要： A weight sensing pad assembly includes a pad that is comprised of a resiliently compressible material. The pad is positionable beneath a mattress of an ambulance gurney. In this way the pad is exposed to the weight of a patient lying on the ambulance gurney. An electronic scale is integrated into the pad to sense the weight of the patient when the patient lies on the ambulance gurney. The electronic scale displays weight indicia comprising numbers communicating the weight of the patient in kilograms. In this way the electronic scale facilitates emergency responders to accurately determine medication dosages that are based on the patient's weight.

摘要： The present invention relates to an energy supply circuit for instantly supplying power without a power converter and an electronic device which operates only when energy is supplied from an energy source using the same. An energy supply circuit without a power converter according to the present invention comprises: an energy extraction unit 10 for generating power from an energy source; and output unit 20 for supplying power to an external electronic circuit; a switch unit 30 interposed between the energy extraction unit and the output unit 20 to connect an output end of the energy extraction unit 10 to the output unit 20 when switched on; and a maximum power point tracking control unit 40 for generating an open/closed signal for opening or closing the switch unit 30 according to the voltage and current of the energy extraction unit 10. The present invention has a technical feature wherein a turn-on point of the open/closed signal comes at a time when the output end voltage of the energy extraction unit 10 is Vh, and a turn-off point comes at a time when the output end voltage of the energy extraction unit 10 is Vl. Accordingly, the present invention has a simple configuration, low manufacturing costs, has no energy loss due to the power conversion, and has no reduction in life due to charging and discharging of an energy storage device.

摘要： Methods of estimating a weight of a vehicle and using the information are provided. Kinematic data of the vehicle, including at least one of a velocity or an acceleration of the vehicle, can be measured at a time. This data can be processed to estimate a weight of the vehicle. This data can be used to adjust autonomous driving, confirm a weight of freight carried by the vehicle, transmitted to external devices, or used in other ways.
