Abstract: Various embodiments of the present invention are directed to methods of preparing a biogas purification system. Embodiments include flushing an adsorber with a gas stream that is separable by the downstream biogas purification process. Other embodiments include using the separable gas stream to flush a saturated adsorber. Additional embodiments include using a gas stream comprised of CO2.

Abstract: A viewing device for an aircraft pilot, the device comprising: a support for positioning on the head of the aircraft pilot; a display surface; display means carried by the support and arranged to display augmented reality objects on the display surface; acquisition means arranged to act in real time to acquire first data representative of the position and of the orientation of the support, second data representative of the position and of the orientation of a cockpit of the aircraft, and third data defining congested zones occupied by equipment of the cockpit, and to acquire the augmented reality objects; and processor means arranged to act in real time to define positions for the augmented reality objects, so that all of the augmented reality objects are positioned outside the congested zones when they are displayed on the display surface.

Abstract: A compressed audio/video, includes circuitry to measure the relative synchronization of decompressed audio and video signals. If audio and video signal synchronization is within a first range of values, synchronization circuitry within the receiver will attempt to appropriately time align the signals. Alternatively, if actual synchronization exceeds the first range, attempts to synchronize the signals are suspended and non-synchronized decompressed audio and video signals are provided.
