Abstract: A print control device comprises a linear modular component, a driving mechanism, and at least one guide rail. The guide rail and the linear modular component are arranged in parallel, and the driving mechanism is disposed on one end of the linear modular component. A group of sensors are respectively disposed at two ends of the linear modular component. The driving mechanism is configured to: control a print device disposed on the linear modular component to move along the guide rail in a predefined direction. The group of sensors are configured to: detect a position relationship between the print device and the sensor. If the print device arrives at the position of the sensor located in the predefined movement direction, the sensor located in the predefined movement direction stops sending the sensing signal to the driving mechanism, such that the driving mechanism controls the print device to stop movement.

According to the technical solutions of the embodiments of the present application, the safety of the battery can be enhanced.

Abstract: A method for preparing (S)-nicotine by reduction includes conducting a reduction process on an alkene compound as shown in Formula I and/or an iminium cation compound as shown in Formula II, thereby producing (S)-nicotine. The method is simple, safe, reliable, and yields both high purity and high quantities of (S)-nicotine production.

Abstract: A wearable physiological measurement apparatus comprises a base, a bridge member, and a first and second support members movably coupled to the base and the bridge member to surround size-variable an opening for accommodating a care giver's finger therein. A measurement device is coupled to the base and with a probe projecting toward the opening for contacting the finger for vital sign measurement and monitoring. Resilient members are coupled between the base, the bridge member and the first and second support members to bias the base, the bridge member and the first and second support members moving toward each other to grip the finger to maintain proper contact of the probe to the finger.

Abstract: The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.

Abstract: The present invention provide a full-servo label inspection machine and a control method thereof; the machine includes a frame, the frame is provided with an unrolling mechanism, a rolling mechanism, a visual inspection mechanism, a label removal mechanism, and a label replacement mechanism. In the label removal mechanism, when the paper pressing roller is at the label removal position, it presses the material to be inspected downwards to form an angle of less than 180° with the rear end of a label removal plate. After a defective label on the material to be inspected passes the label removal plate, a front end of the defective label curls up and eventually sticks onto the label removal paper. The present invention allows fully automation of the removal and replacement of labels, achieving high inspection efficiency and accuracy.
