A hydraulic door closer capable of reducing oil-pressure therein at high temperature, comprises a housing with an oil chamber, an oil storage cavity, and a piston in the housing of the hydraulic door closer. The oil storage cavity is in communication with the oil chamber; when the oil temperature increases, hydraulic oil in the oil chamber and oil storage cavity generates an increased oil pressure move the piston, whereby volume of the oil storage cavity is enlarged, such that oil from the chamber will flow into the cavity, to reduce the oil pressure of the chamber and cavity. When the oil temperature decreases, the oil pressure in the chamber and cavity is reduced, whereby the storage piston restores its original position, whereby volume of the cavity will be reduced, and the oil in the cavity flows back into the chamber. The pressure in the oil chamber is reduced when the hydraulic oil expands due to increased temperature to prevent failure of the seal and to avoid hydraulic oil leakage.

A vehicle comprising a plurality of walls defining a volume adapted to house passengers and/or merchandise and at least one electric battery pack to supply energy for the operation of the vehicle, said at least one electric battery pack being housed in a respective seat made in at least one of the walls and defining with the latter a housing volume comprising at least one cover configured to assume a first operating position in which the volume communicates with the outside environment and a second operating position in which the volume is isolated from the outside environment; the vehicle comprising security means configured to enable the covers to move from the first operating position to the second operating position when a temperature of the electric battery pack and/or a temperature inside the volume exceed/s a pre-set threshold temperature value.

This disclosure is generally directed to a hydraulic door closer, and more specifically is directed to a hydraulic storm or screen door closer that has a fluid overflow chamber providing fluid volume and pressure control for both expanded and contracted fluid at different temperatures. The disclosed hydraulic door closer comprises a fluid overflow chamber adapted to hold sufficient fluid to maintain required operating fluid or oil levels at different temperatures, and to ensure proper closer performance under both extreme high and low temperature conditions.

A vehicle occupant safety system includes temperature, ambient, and interior monitoring modules. The temperature monitoring module includes at least one temperature sensor. The temperature monitoring module is configured to detect temperatures in zones within an interior of a vehicle. The ambient temperature sensor is configured to detect an ambient temperature within the interior of the vehicle. The interior monitoring module is configured to: based on the detected temperatures of the zones, determine for the zones at least one of a temperature gradient over time or a temperature gradient over space; determine if the ambient temperature is outside a predetermined range; and in response to the ambient temperature being outside the predetermined range and based on the at least one of a temperature gradient over time or a temperature gradient over space, detecting an occupant in the vehicle and performing a countermeasure to prevent an injury to the occupant.

A device for controlling a vehicle is provided. The device includes an input device for receiving a user input, a state sensing device for sensing a vehicle state change in response to the user input, and a controller configured to determine whether to apply a driving current of an actuator to a switching device based on the vehicle state change.

A safe assembly includes a housing having a top wall, a bottom wall, a first side wall, a second side wall, a rear wall and a door. The door having a locking mechanism to releasably lock the door in a closed position. Each of the walls includes an outer panel of steel material defining an exterior of the housing. An inner panel of steel material is spaced from the outer panel and has an exterior face facing the outer panel. The exterior face comprises a highly reflective surface. An insulating material is positioned between and fills a space between the outer and inner panels. A plurality of mating flanges is attached to the walls such that each of the walls includes a mating flange securable to a mating flange on one more adjacently positioned one of the walls to form the completed housing.

A brake arrangement for a drive apparatus includes a brake case (15), a first brake element (17), a second brake element (19), and a preload (21) for preloading one of first brake element (17) and second brake element (19) onto the other of first brake element (17) and second brake element (19). A brake arrangement for a drive apparatus, which brake arrangement exhibits a substantially temperature-dependent and consistent braking action, is realized in that an intermediate element (20) is arranged between the first brake element (17) and the second brake element (19), and the first brake element (17) and the second brake element (19) are spaced apart from one another by the intermediate element (20).

A method for responding to a fire-critical battery state in a motor vehicle having at least one battery, and a motor vehicle designed to carry out such a method. A battery temperature of the at least one battery of the motor vehicle is continuously detected by at least one temperature sensor. The method includes the following steps: Continuous detection of a temperature change in the battery based on the continuously detected battery temperature; verifying whether the detected temperature change exceeds a specified threshold defining a fire-critical battery state; and activating at least one vehicle function in order to perform a protective and/or warning measure by a control unit, if the fire-critical battery state is reached.
