Portable object with a wristband including a keyboard
First Claim
1. A portable object with a wristband including a keyboard with control keys bearing symbols oriented so a to be able to be read in the direction of the length of the wristband, said keys being distributed over the length of the wristband, a processing unit for data introduced via the keyboard, at least one display device for displaying in the direction of the length of the wristband characters introduced using the keyboard and processed by the processing unit, and a power source for the electric power supply of the electronic components of said object, wherein at least one integrated encoding circuit is placed in the wristband so as to act as a communication interface between the keys of the keyboard and the processing unit which is integrated in a case of the object.

Abstract
A wristwatch (1) includes a keyboard whose control keys (4) are distributed over the length of the wristband (3), a processing unit (19) for data introduced via the keyboard, at least one display device (6) for displaying time functions and/or data provided by the processing unit, and a power source for the electric power supply of the electronic components of the wristwatch. In order to allow the use of its keyboard, the wristwatch (1) is placed on a work surface, the length of the wristband (3) facing a user. The display of the alphanumerical characters (7a) occurs in the direction of the length of the wristwatch, i.e., rotated by 90° with respect to the usual time display (7b). At least one integrated encoding circuit (9) acts as a communication interface between the keys (4) of the keyboard and the processing unit (19) integrated in the case of the wristwatch. The encoding circuit is placed in the wristband (3) and communicates with the unit via one of the two electric supply wires of said circuit. The distribution of the keys of the wristband may change as a function of a determined country.

18. A portable object with a wristband, comprising:
-
a keyboard with control keys bearing symbols oriented so as to be able to be read in the direction of the length of the wristband, said keys being distributed over the length of the wristband, a processing unit for data introduced via the keyboard, at least one display device for displaying, in the direction of the length of the wristband, characters introduced using the keyboard and processed by the processing unit, and a power source for the electric power supply of the electronic components of said object, wherein at least one integrated encoding circuit is located in the wristband so as to act as a communication interface between the control keys of the keyboard and the processing unit which is integrated in a case of the object, and wherein the integrated encoding circuit receives metal electric connection paths of the keyboard control keys, and transmits to the processing unit electric signals, representative of each character introduced by the control keys, on one of two electric supply lines of said integrated circuit. - View Dependent Claims (19)
