Abstract: An automatic alarm system has an alarm device having a sensor and a telephone having a telephone number. The telephone may be wireless. When the sensor senses a predetermined environmental indicator, the alarm device calls a receiver in a location separate from the alarm device to send an alarm. The receiver may identify the location of the alarm device by its telephone number or an identification code. The receiver can call the alarm device to confirm the alarm and monitor events around the alarm device. The alarm device may include a camera.

Abstract: A communications system for locating, tracking, and messaging between people, which preferably includes a satellite, global positioning satellites, ground monitoring units, and a portable-transmitter-receiver unit to locate and track objects and people. A communications satellite system can transmit and receive messages concerning the location and situation of an object or person. A location system may operate by way of global positioning satellites. The portable transmitter-receiver can activate a signal to the satellite system, which can inform the ground monitoring units that a person is in need of help. Each transmitter-receiver can contain memory that allows for identification of the wearer and can provide information such as address, medical problems, emergency contacts, etc.
