Abstract: A portable security system includes a portable wireless link and a portable motion sensor, which is adapted to receive control signals from the portable wireless link, and which is adapted to communicate a signal when a security breach occurs. A method of providing security is also described.

Abstract: A cellular phone contains a scanner feature for scanning documents directly into a cell phone. The cell phone may scan a small document (e.g., a business card) or a much larger: document (e.g., multiple pages of standard 8½?×11? paper.). Business card scanning can include a feature to automatically enter data into a contact list, which is then synchronized with a host PC. The particular scanning and stitching methods disclosed in a cell phone are capable of scanning objects that are virtually limitless in size and/or shape, making use of even a low resolution camera integrated into many currently available cell phones. In first embodiments, the disclosed scanner makes use of an external scanner interfaced directly to a digital port of a cell phone, and in second embodiments, the scanner uses a low resolution internal camera to capture images of matrixed portions of a larger object or document.

Abstract: A set of usage rules are implemented to disable particular features of a wireless device (e.g., audible ringing, use of camera, etc.), or to forcibly power down the device, based upon it's presence in an area with restricted usage rules. A number of BLUETOOTH™ enabled or other suitably enabled devices such as a cell phones, personal digital assistant (PDA), pager, and email device such as a BLACKBERRY™ or SMARTPHONE™ device, may be automatically instructed to enact one or more rules provided by a Rules Enforcer Transceiver. A “Rules Enabled” cell phone or other wireless device thus may be taken into sensitive areas such as hospitals, movie theatres, etc. For instance, audible ringing may be disabled (or, alternatively, silent ringing such as vibration may be forcibly enabled.) Similarly, camera functionality may be disabled when entering given establishments that prohibit use of such devices, e.g., health clubs, spas, or corporate offices to prevent industrial espionage, etc.
