Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for predicting agent response times. One of the methods includes continually updating, at each time step of a plurality of time steps, an accumulated measure of surprise for the agent due to the movements of another entity in the traffic environment. A distribution of previously predicted trajectories is obtained at a previous time step for the other entity in the environment. A measure of surprise is computed from the perspective of the agent. An accumulated measure of surprise is updated for the time step using the computed measure of surprise for the agent. If the accumulated measure of surprise crosses a threshold at a particular point in time, a predicted response time for the agent is generated based on the particular point in time that the accumulated measure of surprise crosses the threshold.

Abstract: The embodiments of the present application provide a battery assembly, a battery module and a battery energy storage device.

Abstract: A battery energy storage module and a battery energy storage device. The battery energy storage module comprises: a structure body (101), a support member (102), and a cell group (103). A cavity for accommodating the cell group (103) is formed inside the structure body (101). The structure body (101) is provided with an opening. The cell group (103) is disposed in the cavity of the structure body (101) through the opening of the structure body (101). The support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101). Because the support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101), the battery energy storage module can have strong impact resistance, and can be applied to a full vehicle environment alone without being disposed in a protection tray.

Abstract: A lidar system, including: a laser, an optical detector, a laser antenna, and a silicon-based integrated magneto-optical circulator. The silicon-based integrated magneto-optical circulator includes a silicon-based integrated Mach-Zehnder interference structure or a silicon-based integrated micro-ring structure, and silicon-based integrated magneto-optical waveguides. The silicon-based integrated magneto-optical circulator further includes an input port, a receiving port, and an emission port. The laser is aligned and coupled to the input port of the silicon-based integrated magneto-optical circulator via an optical fiber, a grating coupler, or an edge coupler. The optical detector is aligned and coupled to the receiving port of the silicon-based integrated magneto-optical circulator via the optical fiber, the grating coupler, or the edge coupler.

Abstract: A two-part polyurethane composition including a first pack and a second pack. The first pack includes at least one hyperbranched copolymer having OH groups and which is prepared from at least one or more monomer(s) having at least two unsaturated C—C bonds and one or more monomer(s) having one unsaturated C—C bond and one hydroxyl group in the presence of a cobalt (II) complex. The second pack comprises at least one polyisocyanate. Disclosed is a two-part polyurethane composition which has low viscosity, long pot life, fast cure, excellent weathering and UV resistance and which is suitable for use as a coating.

Abstract: The present invention is directed at water-reducible curing agents for epoxy resins, obtainable by reacting at least one diprimary amine, at least one mono-primary amine and at least one polyepoxy compound, wherein the molar ratio of the primary amino groups to the epoxy groups in the reaction is in the range of about 1.7:1 to 1:1, the ratio of the primary amines in the diprimary amine to secondary amines optionally present in the diprimary amine is more than 1:1, and the molecular weight (Mw) of the diprimary amine is 500 Daltons or less. These water-reducible curing agents show excellent utility in combination with epoxy resins for self-levelling applications and provide excellent finished properties such as high compressive strength, low shrinkage, high impact resistance and high wear resistance in comparison to the commercially available products.

Abstract: The present invention provides an abrasive tool that comprises sol-gel alumina abrasive grains bonded together by a glass-ceramic bond material, the tool comprising from about 35 to 65% by volume void spaces, wherein at least about 75% of the volume of the bond material is located in the bond posts or in a coating on the abrasive grains and in which the volume proportion of bond to grain is from about 0.06 to 0.6.
