Abstract: A passenger seat arrangement for a passenger aircraft includes a passenger seat assembly having at least one passenger seat with a seat supporting frame and a backrest, and a wireless charging system integrated into the backrest. The wireless charging system includes a PED holder having an assembly of permanent magnets embedded within the PED holder configured to a physically hold a PED on the PED holder in place, and a charging pad configured to electromagnetically transfer power to a PED held on the PED holder.

Abstract: A tamper detection system for a life vest storage container (10) on board a passenger aircraft (A), includes a receptacle (4) having an access opening with a closable lid (7); a first electrically conductive monitoring pad (1) formed on the closable lid (7); a second electrically conductive monitoring pad (2) formed on the receptacle (4); a non-conductive sealing member (3) including conductive patches of adhesive on the bottom side of two opposite edges of the sealing member and a conductive element leading between the two patches, the two patches applied to electrically conductive monitoring pads (1, 2); and a monitoring system (5) electrically coupled to the monitoring pads (1, 2) and configured to measure an electrical parameter associated with the electrically conductive path (C1, C2, CS) formed by the monitoring pads (1, 2) and the electrically conductive element within the sealing member (3).

Abstract: An electrical power distribution system has a converter module having a converter to convert AC voltage from AC voltage sources to DC voltage and provide DC voltage power with adjustable maximum power values at electrical output interfaces of the converter module to a maximum module power value. It includes a power profile management device to negotiate individual power profiles with electrical consumers connectable to the electrical output interfaces, according to which individual power profiles electrical power up to a negotiated maximum power value is provided by the converter via the electrical output interface. The device detects instantaneous actual power consumption with which an individually negotiated power profile and calculates a power reserve value of the converter as the difference between negotiated maximum power value and instantaneous actual power consumption and negotiate with consumers whose power reserve value is higher than an adjustable reserve threshold value a new power profile.

Abstract: A passenger seat arrangement for a passenger aircraft includes a passenger seat assembly having at least one passenger seat and a seat supporting frame, at least one seat fastening rail which can be installed in a cabin floor of the passenger aircraft and in which the seat supporting frame is mounted, a first electronic housing in which electrical power converter components are arranged and which is mounted on the seat fastening rail, a second electronic housing in which electrical output ports for connecting electronic terminal devices are arranged, and wired cabling which electrically connects a supply port of the electrical power converter components of the first electronic housing to the electrical output ports of the second electronic housing.

Abstract: An electrical power distribution system with least one converter module having a converter to make electrical DC voltage power with adjustable maximum power values available on a multiplicity of electrical output interfaces of the converter module up to a maximum module power value and a temperature control apparatus having a temperature measuring apparatus. The temperature control apparatus is coupled upstream of the at least one converter module to adapt the maximum module power value of the at least one converter module as a function of the temperature of the power distribution system as measured by the temperature measuring apparatus. The temperature control apparatus is designed to create a profile of the temperatures measured by the temperature measuring apparatus as a function of the maximum power values made available by the converter.
