Embodiment Construction

[0030] The following description relates to a method of wireless transmission of information between two units, each of which has means for sending and / or receiving signals. For example, the signal is a short-range radio frequency signal. The unit includes a computer station and an electronic watch. Likewise, an information transmission between two computer stations or two portable devices, such as two wrist watches, is also conceivable by means of the information transmission method according to the invention.

[0031] Since various types of information can be sent according to the method according to the invention, the remainder of the description is mainly concerned with the transmission of information about the diary function between the electronic watch and the computer station, such as the transmission of data about the menu of the diary function, such as the diary , address, log data and parameters.

[0032] In the example shown in FIG. 1 , the device for implementing...

Abstract

The method is one of wireless transmission of information between two units consisting primarily of a portable object, such as a personalized watch ( 1 ), and a computer station ( 20 ). Each unit includes signal transmitting and / or receiving means ( 2, 24, 26 ) switched alternately to a transmitting mode and into a receiving mode. Information is transmitted by transmitting a plurality of information frames alternately between the two units. Each information frame comprises a synchronization field, which includes a particular number of synchronization bytes, an information packet and filler bytes. On receiving a frame, the receiving unit counts the synchronization bytes. The receiving unit transmits, in a heading of the information packet, a synchronization indication which is a function of the number of synchronization bytes received. The synchronization indication is used to correct the size of the synchronization field of the next frame received by the receiving unit. These synchronization field size correction operations are effected in a similar manner in both units.

Description

technical field [0001] The invention relates to a method of transmitting information between at least two units consisting of two computer stations, or two personal portable devices, or a computer station and a personal portable device. For example, said portable device is a personal watch. In order to implement the method, the portable device, such as a watch, and the computer station each include means for sending and / or receiving signals, and the means for sending and / or receiving signals are active in the sending and receiving modes, respectively . The transmitted short-range radio frequency signal comprises at least one information frame modulated on a carrier selected from a plurality of carriers available in the computer station and / or in the watch. The information in the frame relates to data stored in the memory of the watch, for example, or transmitted from the memory to the computer station. Said information may also relate to a command to perform an action or a ...
