Abstract: A motion sensor capable of detecting the direction of motion in three dimensions is disclosed. The motion sensor can be built into a printed circuit board allowing for simple and cost effective manufacturing. The motions sensor is designed to utilize a through hole in a printed circuit board, which is capped by on each side by housings creating a cavity where a spherical metal ball can move in three dimensions. This interior surface of the through hole and the housings have conductive element that when in contact with the spherical metal ball close a circuit creating an electrical signal indicative of direction.

Abstract: A secured area access system for providing access to a protected area is disclosed. In one embodiment, a vehicle access security system, comprising a transmitter, a detector, an access controller module is taught, wherein the transmitter transmits a modulated secured area access signal into an acoustic or optical communications channel, which is detected by the detector. The detector is adapted to detect the modulated vehicle access signal and further adapted to have a detector output signal. An access controller module receives the detector output signal and performs at least one signal processing function. The access controller compares the processed signal against a encoded signal stored in the memory and if it matches send a unlock signal to the locking mechanism of the secured area, granting access to the area.

The security system unlocks a locking mechanism when both the sensor signal and the tag signal are received by the security system. Preferably, the RFID tag comprises an active RFID chip.

Abstract: A security access system and method is disclosed. In one embodiment, a vehicle access security system, comprising a transmitter element, a detector element, a receiver element, and a computational element is taught, wherein the transmitter element transmits a modulated vehicle access signal into a predetermined communications channel, which is detected by the detector element. The detector element is adapted to detect the modulated vehicle access signal and further adapted to have a detector output signal. The receiver element receives the detector output signal and performs at least one signal processing function, wherein the receiver element has a receiver output signal. The computational element accepts the receiver output signal and compares it to a predetermined access code to determine whether a user shall be granted access to the vehicle.

Abstract: A security system provides interaction between the system's remote control (RC) device and field disturbance sensor/proximity detector. In selected embodiments, the system enables a user to adjust the detector's sensitivity through the RC device. The user puts the system in a programming mode and creates simulated security breach events. The system stores detector output corresponding to the events, and sets the detector's sensitivity based on the stored output. In embodiments, the system includes passive remote capability that automatically performs commands when a user approaches its base station. The base station uses output of the proximity detector to sense a person's movement near the base station, and sends an interrogatory transmission to the RC device. If the device is nearby, it responds to allow the base station to verify the device's identity. After the base station verifies identity of the device, it disarms the security system and unlocks the automobile doors.

Abstract: A remote control (RC) device and base station of a security system communicate automatic passive remote control commands at a lower power level than the level used to transmit other information. Lowering the power level of the passive remote control transmissions from the RC device decreases energy consumption and improves battery life. Additionally, the range of the automatic commands is shortened, potentially avoiding some unwanted door lock activations, security system arming and disarming events, and similar occurrences. At the same time, the range of the user-entered commands does not suffer. In embodiments where the RC device sends passive remote control commands in response to periodic interrogatory transmissions from the base station, the power level of the interrogatory transmissions is lower than the power level of other transmissions. Thus, frequency of unwanted door lock activations and arming/disarming events is decreased, while the range of other transmissions from the base station is unchanged.
