Abstract: A pressure accumulator includes an accumulator housing having first and second ports for receiving first and second pressure mediums, respectively, a movable separating element subdividing an interior of the accumulator housing into at least first and second working spaces, the first working space accommodating the first pressure medium and the second working space accommodating the second pressure medium, wherein the first port is in fluid communication with the first working space and the second port in fluid communication with the second working space. At least one sensor is operatively coupled to the first working space for measuring at least one characteristic of the first working space, and a gas generator is operative to generate a gas from ambient air, the gas generator including an outlet for outputting the generated gas, the outlet in fluid communication with the first port.

Abstract: A playlist containing a plurality of tracks is filtered to generate a customized subset or window of tracks for playback. The method includes automatically determining user preference data for each of the plurality of tracks based on the user's conduct when each of the plurality is accessed for playback. The tracks in the playlist are reordered after each track is accessed based on the user preference data. A subset of the playlist is selected for playback based on the reordered track arrangement.

Abstract: A method for navigating among tracks uses limited input commands. A plurality of tracks is associated with a currently playing queue. One of the tracks in the queue is identified for a current focus. A voice command is received that includes a directional aspect and a metadata filtering aspect. In response, the focus moves to a second track having a different value for the selected metadata filtering category.

Abstract: Automatically maintaining, for life tracking purposes, the correct set of replaceable components in systems with variable configurations and replaceable components using replaceable component data from four sources to determine the correct set of replaceable components for life tracking purposes. The four sources are: 1) hardware driven sensor data provided by the low level system control computer, 2) machine modification data from the list of upgrades that have been performed on the system, 3) configuration specific replaceable component data based on the replaceable component information that is known about each possible system configuration, and 4) replaceable component information obtained by prompting the field service engineer for any supplemental information that cannot be determined automatically from the first three sources.
