A small thin display unit that can be installed in the flight deck for displaying only flight crew-selected tactical information needed for the task at hand. The flight crew can select the tactical information to be displayed by means of any conventional user interface. Whenever the flight crew selects tactical information for display, the user interface sends a corresponding request for tactical information to a computer system. The computer system processes the request, including periodically retrieving measured current values or computing current values for the requested tactical parameters and returning those current tactical parameter values to the display unit for display.

The present invention relates to an incremental magnetic encoder (10) defining an encoder axis (X) and comprising a fixed body and a movable body.

One of the bodies, called the first body (21), comprises a first support (33) comprising N arranged magnetic elements.

The other body, called second body (22), comprises: a second support (41) comprising K*M magnetic elements arranged inhomogeneously along the direction of encoding (C1, C2) opposite the N magnetic elements, the K*M magnetic elements forming M groups of K magnetic elements, initial elements of the M different groups being spaced apart along the direction of encoding (C1, C2) by a homogeneous pitch P1, the K1 magnetic elements of each group being spaced apart from the initial magnetic element of said group by variable pitches Pi; at least one magnetic detector arranged opposite the first support (33).

A bead design allows the bead to be removably attached to a rail, allowing the bead to slide along the rail without coming off. The rail can be part of a bracket system to hang the rail in various desired locations. The beads can be made in various shapes and sizes, or with various textual indicators, to provide a user with a memory aid. A user can, for example, have a bead for each medicine dose they are required to take. A user can slide the bead to one side when the medicine is taken. Each bead can include an indicator, for example, 6 am, 2 pm, 10 pm that indicates a medicine to be taken 3 times a day. The beads can be used for other reminders and can be designed accordingly. A software application can be designed to mimic the bead and rail system.
