## Background
PRIORITY REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. Provisional Application No. 61/130,784, entitled JACKET LOCATOR, filed on Jun. 2, 2008 by inventors Eyal Bychkov, Tal Engelstein, Yair Leshem, Uri Ron, Ron Levy and Hagit Perry.


FIELD OF THE INVENTION
The field of the present invention is wireless communication.
BACKGROUND OF THE INVENTION
With advances in miniaturization of electronic components, ever smaller consumer electronic devices are becoming available. Mobile phones, PDAs, cameras and media players are some examples of such devices. These and other devices have become so small that they fit inside a shirt pocket. As a result, people are tending to misplace these devices.
Various solutions have been proposed to locate misplaced electronic devices. One such solution uses sets of electronic locators, which are attached to the small devices. An example of such a locator is the KeyRingerTM manufactured by Sierra Systems of Oakland, Calif. When one of a set of KeyRingers is pressed, the other KeyRingers produce audible and visible indications, which enable an owner to find them.
Another such solution uses a transmitter and a receiver, where the receiver knows its distance from the transmitter. The transmitter is generally attached to a small device, and the receiver indicates to an owner when the distance between the receiver and the small device exceeds a predefined threshold.
A drawback with conventional solutions to locate misplaced devices is that the transmitters, which are attached to or embedded in the devices, require a power source, typically a battery. If the battery is not regularly replaced or recharged, then the transmitters fail.
It would thus be of advantage to have a locator for electronic devices that does not require transmitters attached to or embedded in the devices.
SUMMARY OF THE DESCRIPTION
Aspects of the present invention provide a system and method for locating electronic devices, without the need for attaching or embedding transmitters to the devices.
Embodiments of the present invention relate to a modular wireless communicator that attaches to a plurality of electronic devices referred to herein as jackets. The wireless communicator enhances the jackets by providing them with wireless connectivity, and the jackets enhance the wireless communicator by providing electronics and interfaces. In an embodiment of the present invention, the wireless communicator has an embedded global positioning system (GPS). The GPS operates in conjunction with the wireless communicator so that at locations where GPS signals are weak or unavailable, such as indoors, the GPS uses cellular location sensing capabilities to determine position. An example of such an enhanced GPS is the eGPS® system manufactured by CSR plc of the United Kingdom.
The wireless communicator maintains a history log of the jackets to which it is attached, and the locations and times of attachment to and detachment from these jackets. The history log includes entries that record (i) a jacket identifier, (ii) a GPS location, and (iii) a date & time. A history log manager adds new entries to the history log when log trigger events occur. Log trigger events include powering on/off of the wireless communicator, attaching/detaching the wireless communicator to/from a jacket, using the wireless communicator to dial a phone number, using the wireless communicator to send an SMS/MMS message, using the wireless communicator to play an audio/video file, and using the wireless communicator to browse a designated web site.
A user can view the history log on his wireless communicator in order to locate a jacket that he misplaced. Moreover the wireless communicator's GPS generates navigable directions to reach a designated one of any location recorded in the history log.
There is thus provided in accordance with an embodiment of the present invention a locator system for electronic devices including at least one jacket for a modular wireless communicator, each jacket having a unique identifier, and a modular wireless communicator that attaches to each one of the at least one jacket, including a positioning system for identifying a location of the wireless communicator, a clock for identifying a date & time, a log manager, coupled with the positioning system and with the clock, for recording a plurality of entries in a history log, each entry including (i) a jacket identifier, (ii) a location as identified by the positioning system, and (iii) a date & time as identified by the clock, and a controller coupled with the log manager for notifying the log manager of occurrence of a log trigger event, wherein the log manager records a new entry in the history log when it receives a notification of a log trigger event from the controller.
There is also provided in accordance with an embodiment of the present invention a locator method, including maintaining a history log for a wireless communicator that attaches to a plurality of jackets, each jacket having a unique identifier, the history log including a plurality of entries and each entry including (i) a jacket identifier, (ii) a location, and (iii) a date & time, monitoring the wireless communicator for detection of occurrence of a log trigger event, and in response to detection of occurrence of a log trigger event, adding a new entry to the history log.
