Abstract: A navigation system for aiding a human navigating, the navigation system includes a belt having a belt length and opposite belt ends, and includes an elongated compartment; a belt coupling arranged to the belt for coupling the belt ends; a compass sensor arranged to the belt and for sensing the compass direction based on the earth's magnetic field; a tactile unit arranged for tactile communicating a direction to the human; additional tactile actuators arranged to the belt and for communicating a direction to the human. The additional tactile actuators are distributed over the length of the belt. An elongated mesh is provided for arranging the elongated mesh inside the elongated compartment, the additional tactile actuators being arranged to the mesh. A processing unit is configured for controlling the navigation system.

Abstract: Sleep trainer (1) comprising a band (2) with two electrodes (21), (22) for carrying out an impedance measurement and a monitor (3) for receiving a measurement signal. The band has a band pocket (23). An electrical connection is obtained by inserting the monitor (3) into the band pocket (23). Band contact points ((210),220) are provided inside the band pocket (23). Monitor contact points (31), (32) are provided at an external surface of the monitor housing (30). The monitor contact points are flat and hardly protrude above the monitor housing. The band pocket (23) prevents a lateral movement of the monitor and a band pocket wall (231) exerts a pressing force to keep the monitor contact points (31), (32) in an abutting engagement with the band contact points (210), (220). Advantageously, the sleep trainer provides a high level of wearing comfort which contributes to a sleep disorder treatment compliance.
