A vehicle body structure is configured that enables a cabin section and a chassis frame to move relative to each other and enables both strength of the vehicle body and the safety of the occupants during a collision to be ensured with good efficiency. The cabin section serves as the space in which the passengers reside. The chassis frame and cabin section are separate, independent structures connected through a displacement mechanism in such a manner that the chassis frame and cabin section can move separately relative to each other, when a collision occurs. As a result, transmission of the collision impact to the cabin section is alleviated in an effective manner and the strength of the cabin section and chassis frame can be increased.

The invention specifies an apparatus for applying a film (7) to a substrate (2) by lamination. This apparatus has a heating device (12, 19), which makes it possible for different regions of the film (7) and/or the substrate (2) to be exposed specifically to different temperatures. It is thus also possible to process substrates or films which contain temperature-sensitive elements, e.g. security elements based on bacteriorhodopsin. For this purpose, the heating device comprises a plurality of heating elements (19) which can be activated separately, and therefore different regions of a heating surface (12) can be subjected specifically to different levels of heating power. In order to compensate for irregularities on the surface of the substrate or of the film, the apparatus may have a flexible mating surface (21) which is arranged opposite the healing surface and can be subjected to pressure pneumatically by way of a pressure chamber (22). Overall, this makes it possible to produce high-security documents with temperature-sensitive security features, the properties of which meet extremely stringent requirements relating to prevention of manipulation and forgery.

A weapon protection device for enclosing a weapon. The weapon protection device protects the weapon from adverse conditions, including water, dust, dirt and sand. The weapon protection device features a material that is durable and generally puncture resistant, and impervious to water and is lightweight. The material is also heat resistant and tear resistant. The weapon protection device is compact when not in use and requires very little storage space. The weapon protection device features one or more pockets having a flap and an interior region under the flap. The interior region is made of a flexible, stretchy material that allow a user to fire the weapon with either hand while the weapon is inside the protection device when the user places their hand into one of the pockets and against the stretchy interior material. Although the interior material is less durable that the flap layer and the remained of the device, the interior layer is covered and thus not exposed to any elements that could puncture it. The weapon protection device allows the weapon to be used on short notice and does not require removal of the weapon from the weapon protection device in order to use the weapon. A waterproof opening seal, such as a dry sack seal, is provided.

A vehicle includes an electric motor and a battery operable to provide electrical power to the electric motor. The battery system includes a first battery pack and a second battery pack. The first battery pack has a relatively high power density, and the second battery pack has a relatively high energy density. An electronic controller determines a remaining driving range of the first battery pack, and a remaining driving range of the second battery pack. The vehicle has a human-machine interface (HMI) operatively connected to the electronic controller and configured to indicate the remaining driving range of the first battery pack and the remaining driving range of the second battery pack. The controller executes a method of monitoring the battery system.

An air venting device for venting air from a fluid system, the air venting device comprising an air chamber, a sensor and an air venting valve. The sensor can detect a fluid level in the air chamber without coming into contact with the fluid and the air venting valve can be driven on the basis of this sensor measurement.

An edge of the slit 7 has unevenness. In sealing, a protruding portion 16 of the uneven edge comes into contact with the inner surface of the hollow seal part 4.

A protective device is installed about the outer edge or outer edges of a floor sign. When installed, the main body portion of the protective device is taller than the thickness of the sign such that an item being moved over the sign will ride on the top of the protective device as it passes over the floor sign. The protective device includes a tapered outer edge that helps an item to slide up onto the top surface of the protective device and decrease the impact force of the device when it initially encounter the protective device. The inner edge of the protective device is also tapered down to at least the height of the floor sign. The protective device is made from a hard material that is impact resistant and provides a smooth lower friction upper surface. The protective device can be installed with spaced ends to allow liquid to drain from inside the device.
