An armrest for use with a motorized vehicle is provided comprising first and second substantially opposing surfaces elongated longitudinally along the vehicle's interior surface and extending laterally inward therefrom. The armrest also includes a substantially vertical wall portion extending from the inner periphery of the first and second surfaces. The first and second surfaces define a plurality of channels oriented substantially parallel to one another and elongated longitudinally relative to the vehicle, in either a parallel or oblique fashion relative to a longitudinal axis of the vehicle. The plurality of channels is configured to sustain substantial vertical loading and controllably deform under a predetermined threshold lateral crush load. In addition, the plurality of channels preferably includes one or more partitions within each of the channels that are oriented relative to one another to thereby create a load path for lateral loads imparted to the armrest assembly.

Laser cut bioabsorbable intraluminal devices or stents and methods for forming such an intraluminal device or stent. A precursor sheet or tube of bioabsorbable material is laser cut in the presence of an inert gas to form an intraluminal medical device or stent having a desired geometry or pattern. The device or stent may comprise a helical, or other shape, having the laser cut geometry or pattern imparted thereon. The device or stent may further comprise drugs or bio-active agents incorporated into or onto the device or stent in greater percentages than conventional devices or stents. Radiopaque materials may be incorporated into, or coated onto, the intraluminal device or stent. Precise geometries or patterns are simply and readily achievable using the laser cutting methods in the presence of an inert gas while minimizing damage to the precursor materials.

An energy-absorbing hood assembly for a vehicle includes an inner layer operatively secured to an upper layer having a first interface surface. The inner layer has opposing first and second surfaces defining a sinusoidal profile that is oriented to extend from the forward end of the vehicle towards the rearward end of the vehicle. The sinusoidal profile includes varying amplitudes and wavelengths along different regions of the hood assembly. The amplitudes and wavelengths are individually configured to provide regionally distinct predetermined levels of absorption and attenuation of kinetic energy imparted to the hood assembly by an object upon impact therebetween. Preferably, the hood assembly also includes a lower layer having a second interface surface; wherein the inner layer has a plurality of bonding surfaces attached to the first and second interface surfaces to thereby define a plurality of laterally oriented channels.

The invention discloses an equalization management system and method for a nondestructive lithium battery. The equalization management system for the nondestructive lithium battery comprises at least two battery modules, wherein each module comprises a single battery, an equalizing circuit and a single chip microcomputer; and the single chip microcomputer is connected with the single battery and the equalizing circuit and used for obtaining the voltage of the single battery and the information of the equalizing circuit so as to provide relevant control and protection. An equalization management module is connected with the single chip microcomputer and used for generating a reference signal according to the voltage of the single battery provided by the single chip microcomputer. The single chip microcomputer in each battery module controls the equalizing circuit to equalize the single battery according to the reference signal, and the equalizing circuit shunts or additionally discharges the single battery which needs to be equalized, so as to achieve equalization. Meanwhile, the energy can be recycled, the system efficiency is improved, and the power consumption is reduced. The battery equalization management system and method disclosed by the invention are applicable to various working conditions of a battery pack and have the characteristics of simple and modular structure, strong practicability and energy recovery.
