Methods, systems, and computer program products for generating alerts by matching audio signatures from trusted smart devices are provided herein. A computer-implemented method includes converting one or more captured audio signals originating from a given area of a given environment to one or more audio signatures, wherein the one or more audio signatures correspond to one or more pre-defined user actions within the given environment; comparing the one or more audio signatures to one or more audio signatures associated with one or more user devices authorized to access the given area of the given environment; generating, based on said comparing, an alert upon a determination that the audio signatures do not exceed a threshold level of similarity with respect to the audio signatures associated with the one or more user devices authorized to access the given area; and outputting the alert to one or more of the user devices authorized to access the given area of the given environment.

An ultrasonic pool occupant sensing device capable of using ultrasonic pulses to analyze the occupancy level of a swimming pool. An ultrasonic transducer sends and receives ultrasonic pulses. A front end electronics has a driver for controlling the transducer, a pre-amplifier, band-pass filter, and amplifier combination for filtering received signals. The digital processing unit contains a timer unit for generating pulses, an AD converter for digitizing received pulses, a signal processor for determining data about the return pulse, and an I/O unit for transmitting data to the central processing unit. The data may be an estimate of the number of people in the sensor range, or it may be data about the return pulse that can be analyzed by the central processing unit.

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 system for monitoring animate presence, including one or more ultrasonic transducers configured to transmit an ultrasonic signal, one or more ultrasonic receivers configured to receive an echo signal in response to the transmitted ultrasonic signal, an electronic circuit for comparing the transmitted signal to the received echo signal and identify a phase shift between the signals; wherein the electronic circuit identifies animate presence based on the identified phase shift.

Systems and methods to provide a portable alarm are disclosed herein. The portable alarm may be configured to detect relative movement between a closure of an aperture and a wall forming the aperture. The portable alarm may include a detector body and a detection body. The detector body may include a detector body mount, a first sensor, a transducer, a light source, and control electronics. The detection body may include a detection body mount and a second sensor. The control electronics may be configured to control the transducer and/or the light source to generate a first feedback indicating close proximity between the first sensor and the second sensor and to control the transducer and/or the light source to generate a second feedback different from the first feedback, subsequent to provision of the first feedback, responsive to a reduction in proximity between the first sensor and the second sensor.

The present disclosure describes a system and method designed to protect the contents of a region or space within a facility (e.g., building, home, vehicle, outdoor space, etc.). The system is configured to identify an area to be protected (e.g., nightstand, medicine cabinet, safe), monitor surroundings, and manage and deploy response(s) to threats to the region or space under protection. The system may also be configured to provide incremental warnings, interventions, or countermeasures to deter people or animals from accessing the Protected Space.
