Methods, systems, and apparatus, including computer programs encoded on computer storage media, for reduction of false detections using an ultrasound emitter. One of the methods includes obtaining sensor data captured by a sensor of a property monitoring system; detecting an object represented by the sensor data; determining that the object represented by the sensor data is likely a non-object of interest and being detected as an object of interest; and in response to determining that the object represented by the sensor data is likely the non-object of interest and being detected as the object of interest, sending, to an ultrasound emitter, a command to cause the ultrasound emitter to emit ultrasonic sound around the sensor.

A hub device including a housing defining an interior, a plurality of sensors, and a controller module. The plurality of sensors being provided within the interior or along a portion of the housing. The controller module having access to a memory comprising a set of preloaded software and a set of additional software. At least one of least one of the set of preloaded software or the set of additional software is configured to allow the hub device to be communicatively couplable to at least one additional hardware.

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.

Techniques for calibrating presence-detection devices to account for various factors that can affect the presence-detection devices' ability to detect movement. Presence-detection devices may detect movement of a person in an environment by emitting ultrasonic signals into the environment, and characterizing the change in the frequency, or the Doppler shift, of the reflections of the ultrasonic signals off the person caused by the movement of the person. However, factors such as environmental acoustic conditions, noise sources, etc., may affect the ability of the presence-detection devices to detect movement. To calibrate for these factors, the presence-detection devices may use a loudspeaker to emit an ultrasonic sweep signal that spans different frequencies in an ultrasonic frequency range. The presence-detection devices may generate audio data using a microphone that represents the ultrasonic sweep signal, and analyze that audio data to determine an optimal frequency range and/or transmission power for subsequent ultrasonic signal transmissions.

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.

Proposed is a noise avoiding method for a space monitoring apparatus using a sound signal and, more specifically, is a technology that allows the space monitoring apparatus, which uses a sound signal to monitor a spatial condition, to avoid noise in a space to be monitored to correctly determine the spatial condition.

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. 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.

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.
