Abstract: The disclosure relates to the technical field of traction batteries, and in particular to a battery pack and a vehicle comprising the battery pack. The invention aims at the problem of large heat loss in the existing traction battery in a low-temperature environment. To this end, the battery pack of the disclosure comprises: a frame internally formed with an installation site; a battery module mounted in the installation site and comprising a number of cells; and a side beam connected to an outer side wall of the frame and made of a first thermal insulation material. The above arrangement can reduce the heat transfer coefficient of natural convection between the side wall of the frame and the environment, and reduce the heat flux, thereby reducing the temperature loss of the cells.

Abstract: A laser radar receiving system including a laser radar and a reflecting element. The laser radar includes a first reflector mirror, an emitting channel, an emission system and a basic receiving system. The laser beam emitted by the emission system is reflected by the first reflector mirror, reaches a target through the emitting channel, is reflected from the target and passes through the emitting channel, and is reflected by the first reflector mirror and received by the basic receiving system. The reflecting element is provided in an area outside the emitting channel that is unreachable by the laser beam reflected from the target, and is used for reflecting the laser beam from the area outside the emitting channel to the basic receiving system, thereby simultaneously avoiding blind area and stray light interference in short-range measurements, and improving measurement accuracy and expanding the short-range measurement range of radar.

Abstract: A torsion bar restraint system for tracked combat vehicles that aids in the improvement of occupant survival rates when associated with asymmetric threats. The blast mitigating restraint system can reduce the dynamic deflection of torsion bars based on the severity of the blast impulse as needed. Systems comprise one or more components that secure the torsion bar to the hull for protecting against dynamic deflection and lateral displacement. The two disclosed components, an end restraint device and an M-Ring restraining device, can be used in conjunction or independently from each other based on the type of threat likely to be encountered.

Abstract: A system and method to predict rock strength by directly inverting for petrophysical properties. In one embodiment, seismic data is received or obtained from a seismic survey (step 101). The seismic data are then conditioned (step 103) in order to prepare them for an inversion process (step 105). The inversion process has an embedded rock physics model that allows the inversion to be formulated based upon, and thereby outputting or calculating (step 107), petrophysical properties. Rock strength data may then be calculated from the petrophysical properties (step 109).
