BACKGROUND OF THE INVENTION
The present invention described herein relates to the wrist watch where a Radio Frequency Identification Device inlay is embedded securely inside a leather bracelet to ensure that it is well protected. A combination of an antenna and Radio Frequency Identification Device chipset is called an inlay which is embedded in the bracelet during the process of manufacture of the bracelet. The inlay embedded in the bracelet of the watch is custom built & programmed to preconceived requirements. The inlay, before being embedded in the bracelet is laminated and the size is conceived to suit the bracelet design.
The inlay consisting of an antenna and Radio Frequency Identification Device chipset when used in wrist watches is always used in combination with a case made from plastic material since radio frequency does not pass through metal. The advantage of using Radio Frequency Identification Device inlay inside the bracelet is that the case can be made from metals like aluminum, brass, gold, silver, stainless steel, titanium and tungsten.
PRIOR ART
Most of the wristwatch cases are made from metals that are electrically conductive which reduce sensitivity and operational distance of a radio frequency controlled device due to generation of inductive current. Usage of this technology by accommodating the antenna inside the watch case has the constraint that plastic material alone can be used for the case. Further, electrically non conductive materials like plastic poses severe constraints on the designer in achieving desired aesthetics.
Watches using Radio Frequency Identification Device technology is described in patent reference US6724690 (2004) & US6992952 (2006) by accommodating the antenna inside the watch. However, to prevent generation of inductive current, the ring shaped frame or case has slits filled with non conductive resin. Such a construction of the case is cumbersome in mass manufacturing and also has the draw back of a weak joint that would allow the entry of water & dust into the watch.
The patent reference US7151496 (2006) describes the invention of a patch antenna integrated in a wristwatch. The antenna is molded into 2 ends of the wristband and connected to a radio-frequency module integrated into the watch. In this method of integration of an antenna in the wristwatch, the robustness of the entire mechanism depends on the connectivity between the different elements both within and outside the watch. Further, functional parameters like water resistance and aesthetics features like thickness will have to be sacrificed due to the nature of design.
Wristwatch with antenna as described in US 2007/0041275 (2007) has the antenna fitted into the plastic bezel element externally and connected to the internal electronic module. Such a device has the technical disadvantage in terms of the antenna being subjected to physical abuse and poor reliability of various joints resulting in difficulty to achieve water resistance characteristics.

Embedding the Radio Frequency Identification Device inlay in the bracelet of a watch as described in the invention herein is that it gives the added advantage of making the case from different metals like aluminium, brass, gold, silver, stainless steel, titanium and tungsten. Also since the inlay is placed outside the watch, it does not interfere with the functionality of a watch in terms of water resistance and other performance factors.
OBJECTIVES OF THE INVENTION
Main objective of the invention is to locate the radio frequency inlay in such a manner that it functions even with a metallic case thus allowing use of different materials for the watch case.
STATEMENT OF INVENTION
According to this invention a Radio Frequency Identification Device inlay is embedded into the shorter part of a leather bracelet of a watch. The inlay is laminated prior to the embedding of the inlay so that it is protected from extreme environmental conditions to which the inlay would be exposed to.

DETAILED DESCRIPTION OF THE DRAWING
FIG. 1 shows a quartz watch with Radio Frequency Identification Device inlay embedded into the bracelet. The FIG. 1 shows a complete watch consisting of watch case (4), bracelet - shorter part (2), bracelet - longer part (3) & Radio Frequency Identification Device inlay (1). The Radio Frequency Identification Device inlay (1) is laminated to ensure that it is protected and withstands all extreme weather conditions. The Radio Frequency Identification Device inlay (1) is integrated into the shorter part of the strap. The longer part of the bracelet (3) has got no connection with the inlay. The watch case (4) is also isolated from the Radio Frequency Identification Device inlay (1).
FIG. 2 shows the Radio Frequency Identification Device inlay with its components viz: Antenna (5) and Radio Frequency Identification Device chip set (6).
WE CLAIM
1) In a bracelet used to fasten a wrist watch is embedded a Radio Frequency Identification Device inlay that is protected from extreme environmental conditions which a normal watch bracelet may be subjected to.
2) The bracelet of a wrist watch as claimed in claim 1 has an inlay consisting of an antenna and Radio Frequency Identification Device chip set which is laminated prior to embedding the inlay into the bracelet.

03) The bracelet of a wrist watch as claimed in claim 1 to 2 can be made out of
leather or polyurethane.
04) The bracelet of a wrist watch as claimed in claim 1 to 3 can be fitted to a
watch case made from any material like stainless steel or brass or plastic.
05) The bracelet of a wrist watch as claimed in claim 1 to 4 does not interfere
with other performance factors of the watch as a whole.
