CPC Class H04N

An example of operating a display system of a lavatory of a vehicle is provided. The method includes: (i) receiving, at a controller, information indicating that the lavatory is in use; (ii) in response to receiving the information, operating, by the controller, the display system in a first state while the lavatory is in use; (iii) determining, by the controller, that the lavatory is no longer in use; and (iv) in response to determining that the lavatory is no longer in use, operating, by the controller, the display system in a second state.

An image forming apparatus includes a first casing, a pivotable second casing, a pivotable document cover, and a lock mechanism including a movable hook and a fixed hook. The second casing has a document support surface. When the second casing is at a first position in which the second casing covers an upper surface of the first casing, and the document cover is at a fourth position in which the document cover reveals the document support surface, the movable hook is engaged with the fixed hook. When the second casing is at the first position, and the document cover is at a third position in which the document cover covers the document support surface, the movable hook is disengaged from the fixed hook.

A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

The multispectral detection device comprises first and second photodetectors sensitive to two different wavelengths. The two photodetectors are connected to two integration capacitors of two different readout circuits. Two reset circuits are configured so as to initialise the two integration capacitors separately. A first synchronisation circuit is connected to the first readout circuit and to the synchronisation signal and clock signal generators. The first synchronisation circuit is configured in such a way as to
