Disclosed is a burglar sensor arrangement structure for arranging, with respect to a vehicle interior member (10), a burglar sensor configured to detect an intrusion into a vehicle interior. The burglar sensor arrangement structure comprises an ultrasonic wave generation unit (2) for generating an ultrasonic wave, and a throat portion (18) for radiating the ultrasonic wave generated in the ultrasonic wave generation unit, from a outside opening (18a) thereof into the vehicle interior, wherein the vehicle interior member is formed with a groove (20), and the outside opening of the throat portion is opened at a bottom surface of the groove.

A method includes predicting an environmental condition at a location to which a vehicle is travelling, the environmental condition including at least one of water, dust, and pollution, determining that an object within the vehicle is at a distance greater than a threshold distance from an unobstructed window of the vehicle, and then actuating the unobstructed window to a closed position based on the environmental condition and the object being at the distance from the window greater than the threshold distance.

The present invention relates to a forward acoustic scattering based double-transmitter and double-receiver networking target detection system and method thereof. Two transmitting ends and two receiving ends are adopted, anchored at a sea bottom, and arranged in a parallelogram layout. Time of a target crossing transmitting-receiving connection lines is extracted by adopting a proper direct wave suppression method; and unknown parameters of the horizontal distance, the target velocity and the included angle between the target track and the transmitting-receiving connection lines are estimated at corresponding moving time intervals when the target crosses the four transmitting-receiving connection lines according to different crossing modes. An arrangement mode is simple and flexible, and monitoring of sea areas and sea channels can be realized. The information of the time of the target crossing the transmitting-receiving connection lines, extracted by the method, is more accurate and reliable.

A barrier alarm device for reducing the number of false alarms that may occur in a home or business security system. In one embodiment, a barrier alarm device, such as a door or window sensor, determines whether a barrier, such as a door or a window, has been opened, and determines whether a human being is inside a premises in proximity to the door or window. If a human being is inside the monitored premises when the door or window is opened, it indicates that the human being is authorized to be inside the monitored premises, and the barrier alarm device transmits a timed alarm signal to a central security panel, causing a security response to be generated by the central security panel if a predetermined time period elapses without a user canceling the security response.

A porch piracy parcel theft prevention system and method includes a delivery location apparatus configured for adaption to a building to receive a parcel, the delivery location apparatus including a sensor and a parcel locking mechanism. The sensor is configured to detect the presence of a delivered parcel placed into the line of sight of the parcel detecting sensor. The parcel locking mechanism is armed upon entry of a carrier code and disarmed upon entry of a user code. When armed, the parcel locking mechanism is configured to trigger an alarm when the parcel detected locking mechanism detects removal of the parcel from the line of sight of the parcel detecting sensor. When disarmed, the package may be removed from the line of sight of the parcel detecting sensor without tripping the alarm. Among other uses, helps prevent parcel theft from single family dwellings.

A gunshot detection system utilizes an ultrasonic transducer for detecting a blast wave resulting from a gunshot. The system may be linked to alert systems configured for notifying emergency response personnel to the occurrence and location of a gunshot, thereby enabling a rapid response to an active shooter situation.

In at least one embodiment, a computer-program product embodied in a non-transitory computer readable medium that is programmed to provide an alert for a user of an environment outside of the user's visual field of view is provided. The computer-program product includes instructions to receive an echo profile indicative of at least one object outside of the user's visual field of view from headphones and to receive a command indicative of at least one object to detect on the echo profile from the user. The computer-program product includes instructions to generate an alert for the user to notify the user of a detected object in the user's visual field of view in the event the echo profile includes the at least one object.
