Abstract: A tracker that conserves battery power by keeping its cellular module off as long as its modules determine there is no need to turn the cellular module on. The modules include those for detecting motion, detecting whether the tracker is within confines of a geofence, detecting whether the GPS coordinates of the tracker correspond to those most common from past use or correspond to those for work/home, detecting whether wireless connectivity is available other then via a cellular network) and detecting whether the tracker is more than a predetermined distance away from a user's cellular device.

Abstract: A method and apparatus of communication via a hand held device that includes receiving an indication at the device to initiate an emergency call via a wireless network; determining whether the device is configured with a subscriber identity module (SIM) card, wherein the SIM card includes a plurality of numbers; and sequentially calling the plurality of numbers stored on the SIM card based on the determination that the device is configured with the SIM card. Further, the method and apparatus include detecting an emergency indication; connecting to a wireless network; and establishing a communication with one or more emergency service providers based at least in part on detecting the emergency indication, wherein the communication is established via the wireless network.

Abstract: A unit transmits a call initiate signal over a communication network in response to the switch moving from the inactive position to the active position to establish a call with a 911 emergency service operator directly and enable voice communication. The unit is equipped to send a message indicative of ascertained location information of the unit to the 911 emergency service operator at an end of the established call. The unit contacts remote source to ascertain the location information and form the message. The unit maintains establishment of the call at least until the message is sent to the 911 emergency service operator. The unit itself lacks any GPS tracking module.

Abstract: A smoke detector unit with built-in global system for mobile communications (GSM) to effect short message service (SMS) with an end user, and short message service (SMS),data transmission or email, with a central station monitoring (CSM) Events such as low battery condition and excessive smoke detection are reported to the CSM or end user via SMS or email. The unit may be reprogrammed via SMS remotely. The unit may be checked for connectivity between the unit and the CSM or end user via SMS remotely.
