Abstract: An operation vehicle, comprising a vehicle body and a cab provided at a front end of the vehicle body, and further comprising a boom device. The boom device comprises at least seven booms hinged end to end in sequence. When the boom device is in a folded state, a fifth boom and a sixth boom are located on the same straight line, a seventh boom is located below the sixth boom, and end portions of at least two booms in the seven booms are located above the cab. The technical solutions of the present application overcome the defect in the prior art that the flexibility of boom construction of the operation vehicle is low.

Abstract: The present disclosure generally relates to high-performance flexible thermoelectric generators (f-TEGs) for heat concentration and dissipation. In some embodiments, the f-TEGs can be incorporated into wearable devices. The f-TEG device can include an f-TEG network of thermoelectric units that include multifunctional thin copper disks that can be used as electrodes, heat concentrators and spreaders, spacers, and flexibility enablers. Each electrode can include a spacer extending therefrom to suppress the heat loss between the hot and the cold sides through conduction and convection across a thermoelectric pillar disposed therebetween. In some embodiments, the f-TEG network can be associated with a fabric to provide good wearability and comfort even in wet thermal environments.

Abstract: The present invention provides a touch sensor and a method for making the same. The touch sensor includes a substrate, an electrode layer located in a window area, and a frame trace located in a frame trace area. The frame trace includes a plurality of metal wires. Each metal wire includes a metal wire body electrically connected to a corresponding electrode in the electrode layer and an insulation layer wrapped around an outer periphery of the metal wire body. In this way, the width of the frame trace area can be further reduced.

Abstract: This invention relates to indolizine derivatives and their use in medicine. In particular, the present invention discloses novel substituted indolizine derivatives of formula I, or an isotopically labeled compound thereof, or an optical isomer thereof, a geometric isomer thereof, a tautomer thereof or a mixture of various isomers, or a pharmaceutically acceptable salt thereof, or a prodrug thereof. The invention also relates to the use of these compounds in medicine.

Abstract: Disclosed are a bending boom, a boom device and a work machine. The bending boom includes a middle portion and two extending portions. The middle portion is configured to connect external components. The extending portion has a first side wall and a second side wall opposite to the first side wall. The first side wall is flush with middle portion, and the second side wall is bent from middle portion towards a direction near first side wall. The two extending portions are connected to two opposite ends of middle portion. By providing the matching middle portion and extending portions, a situation in which stress concentration occurs at the middle portion can be prevented, which improves stress condition of the bending boom, and improves durability of the bending boom, the boom device and the work machine.
