Patent ID: 7406003

Claim:
An electronic device that includes functionality to perform at least two functions, a first of which is at least timekeeping and the other of which is displaying information related to a measured external parameter of a sensed condition, wherein the electronic device comprises: a multilayered module comprising: a frame having a frame surface; a first printed circuit board which includes first means for timekeeping, wherein the first printed circuit board is intermediate the frame surface and a second printed circuit board; a battery compartment dimensioned for receiving a battery, wherein the battery compartment is asymmetrically positioned within the module thus creating a region above the first printed circuit board and proximate the battery compartment; a removable second printed circuit board physically separable from the first printed circuit board and including second means for receiving information of the measured external parameter wherein the second printed circuit board is securable within the module and positionable in the region; and a display, electrically coupled to the second means, for displaying information related to the measured external parameter; wherein when the second printed circuit board is removed and replaced with another printed circuit board having third means for receiving information of a measured external parameter that is at least in part different from and/or in addition to the means of the second printed circuit board, the functionality of the electronic device is changed and/or modified and the display then becomes electrically coupled to the third means and displays information related to the external parameter measured by the third means.
