摘要:
The invention relates to a portable folding electronic piano comprising several modules (10, 12, 14, 16) consisting of a set of keys that can reproduce the musical notes of a piano with the aid of an associated electronic system. The invention also comprises stiffening means for rendering same rigid, which can occupy two positions after the modules have been unfolded to form a keyboard, namely a first position in which the keyboard can be folded and a second position in which the keyboard is rigid.

The invention concerns a system comprising a dual-chip card (1) including a permanent chip (2) consisting of a microprocessor and a secure programmable memory and a second removable chip (3) including essentially a once-only read memory containing a predetermined credit amount available to the user, and a micro-housing (6) for inserting the card and comprising communication means (11) for communicating with an external terminal (12', 12', 12''', 12'''') designed to record a transaction and interconnecting means for mutually connecting the two chips to decrement the programmable memory by the amount of the performed transaction. The unique read memory of the removable chip contains besides the predetermined credit amount, a unique serial number assigned by the central bank, the amount of credit and the unique number being recorded in the programmable memory by the interconnecting means when the card is first inserted in the micro-housing.

A portable reading device for the blind consisting of a miniature housing (2) attached to a sleeve to be fitted over the tip of the user's index finger like a thimble. The housing (2) includes an optical sensor array (5) and an electromagnetic unit for displaying one printed character at a time in Braille on a tactile surface as soon as the user's finger passes over the character. The electromagnetic unit contains six electromagnets (7) for reproducing Braille characters, and two further electromagnets for indicating incorrect tracking to the user. The latter two electromagnets are activated when the blind user's finger moves too far up or down as it runs along a line of text.

Système de saisie, de traitement et de transmission d'informations constitué d'une pluralité de boîtiers portatifs équipés chacun des moyens de saisie d'informations manuels, optiques et acoustiques et pourvus d'une carte à mémoire comprenant un ou plusieurs microcircuits. Lesdits boîtiers pouvant dialoguer directement avec des bornes extérieures par transmission infrarouge ou via un ligne téléphonique avec un centre serveur ou même avec un autre boîtier. Les boîtiers peuvent également communiquer entre eux selon des critères sélectifs via un centre serveur qui fait office de détourneur d'appels intelligent et sélectif.

The invention concerns a data transmission system for data exchange between a first device consisting of a telephone extension and a communicating pen computer, both connected to the telephone network, and a second device likewise consisting of a telephone extension and a communicating pen computer, said communicating pen computers being of the type comprising a touch-sensitive screen addressable with a stylus. Each pen computer comprises a card reader for receiving a plurality of smart cards (15), each of which enabling to generate a specific application, to manage data and to configure the screen (2) of the communicating pen computer, time or frequency multiplexing means for simultaneously transmitting voice signals supplied by the telephone extension and data supplied by the communicating pen computer. Such a system enables to prepare, transmit, receive and manage messages in written form, optionally during a telephone conversation, and to implement numerous applications generated by the smart cards (15).
