Abstract: A leak alarm system monitors the wetness of a floor. The alarm system comprises a housing having a flat bottom surface and support feet for supporting the housing off the floor such that each one of the support feet is in contact with the floor. Each support foot comprises an electrode of the alarm system. A low resistance condition between two electrodes of opposite polarity, such as occurs in the presence of a water leak, activates the alarm.

Abstract: An improved vehicle intruder alarm system includes a method of automatically arming an alarm system. When arming the alarm system by remote control the vehicle windows can be raised and the vehicle headlights automatically turned on by remote control. When entering a vechicle door while the system is armed, a low warning tone is produced for an entry delay time. The warning tone increases with time. The processor for the alarm senses the magnitude and rate of impacts or motions of the vehicle. Short warnings are produced when the magnitude and rate are above a threshold.
