Abstract: An insulating device can include an opening having a waterproof closure which allows access to a storage compartment within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

Abstract: A method is for determining a profile depth of a tire profile. The method includes at least the following steps: a) detecting an acceleration of a measurement point on a tire inner side of a vehicle tire, wherein a deviation, caused by contact of the vehicle tire with a roadway, of the acceleration of the measurement point within an observation window is detected, b) deriving at least one analytical characteristic variable which is characteristic of the profile of the detected acceleration, wherein the at least one analytical characteristic variable characterizes the non-periodic profile of the detected acceleration within one tire rotation, c) determining the profile depth in a manner dependent on the at least one analytical characteristic variable, wherein a calibration curve yields the dependency between the analytical characteristic variable and the profile depth, and the calibration curve assigns a profile depth to the derived analytical characteristic variable.
