Abstract: The present application provides a backlight module and a liquid crystal display device; the first portion of the slit adhesive is formed with a notch, so that when internal stress generates in the slit adhesive due to environmental changes, the internal stress can be released through the notch, thereby preventing the slit adhesive from warping and improving the yield of the backlight module.

Abstract: Robotic medical systems can be capable of intra-operative setup adjustment. A robotic system can include comprises a kinematic chain for performing a procedure. The robotic system can be configured to detect one or more conditions encountered by the kinematic chain. The one or more conditions can correspond to a respective adjustment to a pose of the kinematic chain. In response to detecting the one or more conditions or upon user request, the robotic system can generate a recommended adjustment of the kinematic chain in accordance with the one or more conditions. The robotic system can present a notification of the recommended adjustment of the kinematic chain to a user. In accordance with a determination that a first user command to execute the recommended adjustment has been received, the robotic system can adjust the pose of the kinematic chain in accordance with the recommended adjustment.

Abstract: The disclosure provides a method for preparing an electrode film layer on a surface of a solar cell substrate. The method includes: a) obtaining a metal electrode material melt by heating and melting a metal electrode material under a vacuum condition; b) bombarding the metal electrode material melt with an ion source at low energy, so that it is sputtered and deposited on the surface of the solar cell substrate to form the electrode film layer; in which the energy of low energy bombarding is 30 eV to 80 eV.

Abstract: A robotic medical system can include a user console, a robotic arm, and an adjustable arm support coupled to the robotic arm. The robotic medical can be configured to control null space motion of the robotic arm and/or the adjustable arm support based on inputs from two or more tasks of a plurality of tasks for execution by the robotic medical system. For example, the plurality of tasks can include contact detection of the robotic arm, optimization of the adjustable arm support, collision and/or joint limit handling via kinematics, robotic arm null space and/or bar pose jogging, and/or motion toward a preferred joint position.

Abstract: The present disclosure discloses a two-layered varied ball diameter packed bed heat storage apparatus and a method of manufacturing a heat storage ball. By arranging large-diameter heat storage balls at an upper layer of a packed bed heat storage apparatus and small-diameter heat storage balls at a lower layer thereof; the packed bed heat storage structure comprehensively considers two important evaluation indicators for a heat storage apparatus: heat storage rate and heat storage density, thereby implementing a design principle of maximizing the heat storage rate density of the packed bed heat storage apparatus; by achieving a best combination of heat storage ball diameters inside the packed bed through an optimized design, the heat storage apparatus is imparted with a best heat storage performance. The present disclosure further provides a method of manufacturing a heat storage ball.

Abstract: A backlight module and a display apparatus are provided. The backlight module includes a film sheet, including a first opening and a second opening; and a light guide plate, including a first limit boss located within the first opening and a second limit boss located within the second opening. The second limit boss limits a position of the film sheet in a first direction; the first limit boss limits the position of the film sheet in a second direction. In the second direction, a first interval between is between a portion of the film sheet that forms the second opening and the second limit boss; and the portion of the film sheet that forms the second opening includes two first sidewalls opposite to each other in the first direction.
