Devices, non-transitory computer-readable media and methods for providing a haptic signal based upon a detection of an object are disclosed. For example, the processor of a device may transmit a first ultrasonic signal via an ultrasonic emitter and detect an object based upon a receiving of a reflected signal via an ultrasonic detector, where the reflected signal comprises a reflection of the first ultrasonic signal from the object. The processor may further monitor for a second ultrasonic signal via the ultrasonic detector. The device may be associated with a user, and the second ultrasonic signal may be associated with a teammate of the user. The processor may also select whether to provide an instruction to a haptic actuator when the object is detected, based upon whether the second ultrasonic signal is received via the ultrasonic detector.

The appliance (1) with volumetric detector, usable in particular in anti-break-in systems for vehicles, comprises support means (2) associable with the structure of a vehicle, inside the compartment, an electronic control board (3) associated with the support means (2), at least a volumetric sensor (4) connected to the electronic control board (3) and suitable for detecting break-ins inside the compartment, and at least one volumetric sensor (4) associated integral with the electronic control board (3) and at least an acoustic duct (6) having a first mouth (7) associated with the volumetric sensor (4) and at least a second mouth (8) for emitting and/or receiving the sound waves generated by the volumetric sensor (4) and/or reflected by at least an obstacle inside the compartment.

A device and method for walker identification. An audio input interface obtains a sampled acoustic signal, possibly from a microphone, a vibration input interface obtains a sampled vibration signal, possibly from a geophone and at least one hardware processor fuses the sampled acoustic signal and the sampled vibration signal into a fused signal, extracts features from the fused signal and identifies a walker based on extracted features.

Disclosed is an apparatus and method for detecting presence of persons or objects within an environment. The apparatus and method may determine a difference in relative position between transmitters having an unknown room position. A transmitter may emit coded signals that may be detected by other transmitters within the room and properties of the coded signal can form a baseline for comparison to new signals after the baseline is established. Through the use of coded signals and relative distance location between transmitters, movement and position of persons or objects within the room may be determined.

A barrier alarm device for reducing the number of false alarms that may occur in a home 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, determines whether a human being is in proximity to the door or window inside a monitored premises. 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 an alarm signal is not transmitted to a central security panel, thus reducing false alarms.

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.

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.

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.
