Abstract
A personal security device includes a motion sensor, such as a MEMS chip. In response to a characteristic motion pattern, especially acceleration of a car, the security device will trigger a consequence. The consequence might be an audible or visible alarm. Optionally the device may communicate with the engine to direct it to take some action, such as stopping or exploding air bags.
Claims14
An anti-kidnapping device comprising:
- a carrier adapted to attach to a person to be protected;
- a motion detector;
- and
- a processor adapted to perform the following operations
- determining whether a current motion detected by the motion detector matches a known motion patter representative of an acceleration of a motor vehicle;
- and
- triggering consequence if a match is found.
4 more elements
A method for enhancing personal security comprising:
- transporting a security device on a person whose protection is sought;
- within the security deice, determining whether a current motion of the person matches a known motion pattern representative of an acceleration of a motor vehicle;
- and
- in response to detection of the motion pattern, within the security device, triggering a consequence.
1 more element
A medium, readable by a processing device, embodying code for performing the following operations:
- determining where a current motion of an attached person matches a known motion pattern representative of an acceleration of a motor vehicle;
- and
- in response to detection of the motion pattern, triggering a consequence.
