Latest Patents
Pfeifer holds a patent for a touch-responsive portable intrusion alarm. This device is ingeniously designed to be encased within a housing that hangs from a doorknob by a conductive strap. The strap makes electrical contact with the doorknob apparatus, allowing the monitoring circuit within the housing to sense capacitance changes when the doorknob is touched by a potential intruder. The alarm is activated by this monitoring circuit, generating either a local audible alarm or an FM transmission signal sent to a remote receiver, or both. The device also features a latching circuit that maintains the alarm in an activated state even after the capacitance has been removed. Additionally, it includes switch means for resetting the alarm and a temporary disabling feature that allows the doorknob to be touched without triggering the alarm.
