  • Publication number: 20190208739
    Abstract: A system may include an aircraft passenger seat implemented in an aircraft and an aircraft passenger computing device implemented in, on, or in proximity to the aircraft passenger seat. The aircraft passenger computing device may be communicatively coupled to an animal crate assembly onboard the aircraft. The aircraft passenger computing device may include an aircraft passenger display viewable by a passenger and a processor communicatively coupled to the aircraft passenger display. The processor may be configured to: receive sensor data from a sensor implemented in or on the animal crate assembly; receive captured animal crate assembly video data from a camera implemented in or on the animal crate assembly; generate graphical data based on the sensor data and the captured animal crate assembly video data; and output the graphical data to the aircraft passenger display for presentation to the passenger.

  • Publication number: 20150130535
    Abstract: There is disclosed a technique for controlling at least one amplification stage, comprising: selecting a linearity objective for the amplification stage; in dependence on an input signal to said amplification stage, determining a combination of supply input and bias input for the amplification stage in order to meet said linearity objective; and in dependence on there being more than one combination of supply input and bias input for meeting the linearity objective, selecting the combination that optimises a further system performance objective for the amplification stage. The further system performance objective may be one or more of: an efficiency objective; an envelope signal bandwidth objective; or a robustness to production tolerance objective.

  • Patent number: 8622403
    Abstract: The invention relates to a transport cart (10) for loading an aircraft galley, comprising a base element (12) and a plurality of wheels (14) attached to the base element (12). Two frame elements (20, 24) are connected to the base element (12) and disposed at a distance from each other. A first guide device (28, 28?, 28?) is set up for engaging a complementary second guide device formed on a box that is receivable in the aircraft galley to be loaded and for transporting on the transport cart (10). The first guide device (28, 28?, 28?) is further set up for securing the box against displacement on the transport cart (10) in a direction perpendicular to a longitudinal axis (L) of the transport cart (10) when engaged with the complementary second guide device formed on the box. The transport cart (10) finally comprises a locking mechanism (40, 40?) which is set up for securing the box against displacement on the transport cart in a direction parallel to the longitudinal axis (L) of the transport cart (10).
