Abstract: Web Applications run as software which is served through a portal or browser. However this precludes their use offline or when connectivity is not present. The present invention is a method for creating offline web applications and managing associated user data which is created offline and must later be reconciled with one or more central servers without a data collision. This allows the system to efficiently know which version of different pieces of user data are new and which need to be added to centralized servers. This method also applies to the actual web application program files so that software applications can be synchronized in addition to user data enabling a transparent online and offline user experience. The method described here also applies to mobile computing devices such as cellular telephones and personal digital assistants. A side benefit of the method introduced here is that data sets can be distributed in manner which allows peer to peer synchronization and filedata distribution.

Abstract: Consumer electronics devices such as remote controls, toys, and other handheld battery powered electronics are often misplaced. The present invention embeds a locating device in the battery for such devices such that when a signal is sent from a wireless transmitter, ultrasonic transmitter, or via human sounds such as clapping, whistling, and speaking or the like, the battery beeps to make the lost device findable. Further enhancements allow for multiple families of devices to be tracked and located, and even communicate battery status back to the user or transmitting device.
