A bicycle fitted with an on-board control system which is adapted in such a way that it can control the state of a functional element of the bicycle, in order to detect an error in the operation of said functional element and in order to signal said error.

Bicycle provided with an on-board control system and automatic rental system comprising said bicycles

An automatic cycle storage system comprising cycles, each of which carries a blocking device and an electronic circuit; a cycle storage area serving to receive the cycles while they are not being used; and a control device adapted to authorize, selectively, cycles to be borrowed from the storage area. The control device and the cycle are each provided with a respective short-range wireless communications interface, and the cycle includes an electrical lock device adapted to lock the blocking device in the blocking position.

The disclosure concerns a light display panel with a matrix of pixels each comprising three monochrome electroluminescent diodes of three colors. The diodes are controlled by a control circuit delivering electrical power P to each diode, said electrical power being expressed in the form P&minus;k.Pr, wherein Pr is a reference electrical power particular to the diodes of each color and k is a coefficient selected according to the display to be presented. Over the course of time the reference electrical power is subjected to different variations depending on the colors, to compensate for the aging of the diodes.

An information system for informing users of a bus network about waiting times for buses at stops in the network. The system includes a system for locating buses coupled to a central point which broadcasts said positions at successive instants &thgr; to receivers adapted to calculate waiting times for the buses on the basis of their positions, which positions reach the receivers after a certain average length of &ldquo;transit&rdquo; time T. In order to ensure that calculated waiting times as are accurate as possible, the central computer point broadcasts to the receivers estimated positions that the buses are expected to occupy at instant &thgr;&plus;T.

A light-emitting display panel comprising an opaque background having a front face of dark color fitted with a plurality of light-emitting elements, the front face and the light-emitting elements being covered by a front optical filter. The front optical filter is a substantially neutral absorbant filter having a transmission coefficient lying in the range 10% to 60% over substantially the entire visible light spectrum, the display panel not having any other optical filter interposed between the background and the front optical filter.
