Abstract: A device for medium separation, in particular for separation of gases, such as air, from a fluid, such as oil, by means of a separating device (22), which is accommodated in a housing (1) and which, when the medium is received via an inlet point (24) of the housing (1), sets this medium in rotation for the purpose of realizing the separation, with the housing (1) having at least one outlet point (26) for gas and at least one outlet point (16) for fluid, which outlet points are separated from one another, and with a filter device (40) being arranged in the housing for the separation of particulate contamination, is characterized in that the filter device (40) is arranged after the separating device (22) when viewed in the direction of flow of the fluid.

Abstract: A person can use a computing device such as a computer, mobile device, or other such device to record the completion of a task. The task can include any task that is verifiable via the sensors associated with the mobile device. These sensors may be, for example, video, audio, a clock, a timer, still image, accelerometer based, gyro based, GPS location, locations according to triangulation, temperature, barometer, and the like. The task can then be sent to another person in the form of a challenge to do something better. The other person can then record a responsive task and send it to the challenger. The decision as to if the challenge has been met or beat can be decided by the challenger or someone else including a large voting audience. In some embodiments, a large number of people can respond to the challenge.
