1. An alarm system comprising:
- a vibration sensor configured to sense vibration of the alarm system and configured to output a first signal upon sensing said vibration;
a magnetic sensor configured to sense changes in distance between the alarm system and a signal-generating device and configured to output a second signal upon sensing said changes in distance;
a speaker;
control circuitry coupled to the vibration sensor, to the magnetic sensor, and to the speaker, wherein said control circuitry is configured to cause an audible alarm through said speaker in response to receiving said first signal or said second signal; and
a housing substantially enclosing the vibration sensor, the magnetic sensor, the speaker, and the control circuitry, wherein said housing comprises a thin profile and is attachable to a first window surface such that said housing is capable of being located between the first window surface and a second window surface upon relative motion between the first window surface and the second window surface.

Abstract
An alarm system includes a housing that substantially encloses a plurality of sensors and an alarm-signal generator. The housing has a thin profile and may be mountable in various locations, such as on a window surface. The thin profile of the housing allows the alarm system to be attached to the surface of a first window and capable of being located between the first window surface and a second window surface upon relative motion between the first window surface and the second window surface.
