Abstract: This disclosure provides an energy storage apparatus, an energy storage apparatus control method, and a photovoltaic system. The energy storage apparatus includes: a plurality of battery clusters, a plurality of conversion units, a start unit, and a controller. The controller includes a plurality of control units. The start unit is configured to: after receiving a start signal, control a control switch in at least one battery cluster to close, to start a control unit corresponding to the battery cluster. The control unit is configured to: determine, based on a state of the control switch in the battery cluster, whether a black start mode is on; and when determining that the black start mode is on, control a DC-DC converter in the corresponding conversion unit to release electric energy stored in a battery pack in the corresponding battery cluster, to energize a direct current bus.

Abstract: A face recognition method includes: acquiring an image to be recognized; and recognizing the image to be recognized based on a cross-modal face recognition network to obtain a recognition result of the image to be recognized, wherein the cross-modal face recognition network is obtained by training based on face image data in different modalities.

Abstract: A rotary joint, including: a hydraulic follow-up mechanism and a rotary transmission mechanism. The hydraulic follow-up mechanism includes a cylinder body, a valve sleeve, a valve core, a valve body, a left end cover and a right end cover. The rotary transmission mechanism includes a tray, a stabilizing ring, a follow-up disk, a torque transfer disk and a stable supporting wheel mechanism. The left end cover and the right end cover are arranged at the left and right ends of the cylinder body, respectively. The valve body is concentrically mounted in a cylindrical hollow chamber of the cylinder body. The output shaft at the right end of the valve body projects out of the right end cover. The right end of the valve core is provided with a valve core torque transfer shaft extending rightwards through the right end of the valve body.

Abstract: The disclosure discloses a printer comprising a feeder, a printing head, a printer RFID tag comprising a tag antenna and an IC circuit part, a communication antenna, and a control device. The control device being configured to execute an information acquisition process for acquiring access point information via a wired communication connecting part from the printer RFID tag, the access point information being acquired by the printer RFID tag by tag communication, a transmission and reception attempting process for attempting information transmission and reception with an access point, by means of the mutually recognized wireless communication, a data acquisition process for acquiring desired print data acquired by the mutually recognized wireless communication when information transmission and reception by the transmission and reception attempting process succeed, and a printing control process for controlling the feeder and the printing head so that printing is performed on a print-receiving medium.

Abstract: Disclosed is an improved microcentrifuge tube (10). One improvement is a recessed well (20) within the top of the the lid (16) of the tube into which an identifying disk (22) is placed. Another claimed improvement is an expanded lower circumference (25) of the lower portion of plug (24) extending down from the bottom of the top (16) of the tube and an inwardly directed protrusion (26) on the inner surface of the top portion of the tube such that the expanded circumference (25) at the lower portion of the plug (24) fits under the inwardly directed protrusion (26) when said plug is inserted into the opening of the tube thus securing the lid to the top of the tube.
