A thermal insulation material for a battery pack includes: a thermal insulation layer; and a first base material and a second base material that are arranged with the thermal insulation layer interposed therebetween. The thermal insulation layer contains a porous structure in which a plurality of particles is connected to form a skeleton, reinforcing fibers, and metal oxide nanoparticles serving as a binder, the porous structure having pores inside and having hydrophobic sites at least on a surface of the porous structure out of the surface and inside of the porous structure, and a percentage mass loss of the thermal insulation layer in thermogravimetric analysis in which the thermal insulation layer is held at 500° C. for 30 minutes is 10% or less.

Thermal insulation material for battery pack and battery pack

A sound isolating wall assembly includes a plurality of walls defining a space between the plurality of walls. At least one acoustic scatterer is disposed within the space between the plurality of walls. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end, with the channel open end being in fluid communication with the opening.

Sound isolating wall assembly having at least one acoustic scatterer

A sound isolation device includes at least one degenerate acoustic scatterer having a plurality of channels. The plurality of channels may include three or more channels. The channels have an open end and a terminal end, wherein the terminal ends of the channels are separate from one another. The at least one degenerate acoustic scatterer has an acoustic monopole response and an acoustic dipole response that have a substantially similar resonant frequency.

Degenerative sound isolation device

A vehicle proposed herein includes a swivel, a lock mechanism selectively locking and unlocking the swivel, a seat mounted on the swivel, a plurality of surface pressure sensors each disposed along an outer surface of the seat and detecting a pressure distribution within a predetermined area of the outer surface, and a controller configured to cause the lock mechanism to be unlocked based on a change in pressure distribution or a surface pressure that is detected by any of the plurality of surface pressure sensors.

Vehicle with improved seat swivel lock mechanism

A switch device includes a base, a mounting member protruding from the base, a plurality of elastic strain sensors, and an input detector. Each of the plurality of elastic strain sensors spans between a top portion of the mounting member and a corresponding one of a plurality of peripheral portions of the base. The plurality of peripheral portions are circumferentially spaced apart from each other around the mounting member. Each of the plurality of elastic strain sensors is configured to change a capacitance according to elongation. The input detector is configured to obtain a change in the capacitance of each of the plurality of elastic strain sensors.
