摘要： A discharge flow rate of a loss-in-weight scale is controlled by continuously changing control outputs to save the time necessary for data stabilization. A curve relating the discharge flow rate and the control output is obtained by using the functional relationship between the control output and time and the functional relationship between the material weight and time. The discharge flow rate can be precisely controlled by directly selecting or inputting a value of the control output, to achieve the objectives of direct controlling and of avoiding the time for data stabilization.

摘要： A method of weighing using a scale (10) comprises the steps of: recognizing at least one of a plurality of objects placed within an object recognition area (A) of a platform (20) of the scale (10), and weighing the plurality of objects placed on the platform (20) of the scale (10) to determine a total weight of the plurality of objects. A weighing device (10) comprises the platform (20) configured as a plane, and utilizes the aforementioned weighing method. The method of weighing is advantageous in that it reduces the difficulty of object recognition using an algorithm by increasing the degree to which the object on the weighing platform fits the algorithm, reduces the complexity of the operation flow and the time required, and effectively increases the precision and accuracy of object recognition.

摘要： A method for operating a measurement device using a blockchain. A blockchain system comprises a lease platform node or lease platform node device, a lessor client, and a lessee client. Existing state information about the measurement device is stored in the blockchain. The method can include receiving a lease order for the measurement device that is sent by a lessee client, sending a lease notification based on the measurement device to the lessor client to notify the lessor to send the measurement device to the lessee, receiving, after the lessee receives the measurement device sent by the lessor, a device state detection request sent by the lessee client or the measurement device, wherein the device state detection request comprises first current state information about the measurement device, and detecting whether the first current state information matches the existing state information, and if yes, creating a lease contract for the measurement device.

摘要： A method and apparatus are disclosed for managing a measurement device based on a blockchain, which is applied to node devices in a blockchain network. The method can include obtaining device state data of the measurement device at various stages in the life cycle of the measurement device; constructing a target transaction based on the obtained device state data, and then sending the target transaction to other node devices in the blockchain network to perform consensus processing on the target transaction; and storing, when a consensus of the target transaction is reached, the target transaction into a distributed ledger of the blockchain network, wherein the target transaction stored in the distributed ledger of the blockchain network is used for life cycle management of the measurement device.

摘要： A key determination method for a metal key. The method comprises a step of determining whether values output by an electrical parameter converter on a metal key satisfy multiple levels of thresholds, and, a step of setting a press flag of the metal key according to multiple levels of thresholds; and after the metal key is released, determining whether a release flag is valid according to a press model, and if so, clearing the press flag that was previously set. Different press models and different thresholds are selected and configured by means of software, so that personalized choices are provided for respective metal keys, which effectively facilitates different operators in configuring a metal keyboard according to usage habits, thereby improving the operating efficiency. In addition, the setting of different thresholds effectively protects the operational details mean for the exclusive use of operators, thereby achieving the required confidentiality.

摘要： A telescoping electric pipette controller has a handle, a head end portion, an outer shell and a manual retainer. One end of the head end portion is arranged in an end portion of the handle in a penetrating manner, the outer shell is sheathed over an outer surface of the end portion of the handle, and one end portion of the manual retainer is rotatably connected to the outer shell. By means of opening or fastening the manual retainer, one end portion of the manual retainer is released outwards or pressed inwards against the head end portion, allowing extension and retraction of the head end portion relative to the handle. The extension and retraction, as well as the locking of part of a grip structure, are controlled by means of a switch, allowing the grip to change the length within a specific range.

摘要： A method and device are provided for diagnosing a weighing system. In the method, the weighing system acquires an intrinsic parameter, a status parameter, and an operating parameter of various components of the weighing system, environmental parameters of the weighing system application, and communication data and interaction data among all the components. A first-level prompt is sent when the status of any of the components is abnormal, such that the system stops operating. A second-level prompt is sent when the status of each of the components is normal and the service life status of at least one of the components reaches a preset threshold. A third-level prompt is sent when the status of each of the components is normal and a system performance abnormality event is identified for the performance status of the system. A fourth-level prompt is sent when the status of each of the components is normal.

摘要： An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.

摘要： A weighing method comprises the steps of: recognizing one or more objects to be detected on a first scale platform top (A) or within an object recognition area of the first scale platform top (A), and weighing the objects to be detected that are placed on a second scale platform top (B). A weighing system comprises at least two scales having scale platform tops utilizing the weighing method outlined above. The weighing method reduces the difficulty of algorithm recognition by increasing the degree to which the object on the weighting platform fits the algorithm, reduces the complexity of operation flow and the time required, and effectively increases the precision and accuracy of object recognition.
