Patent number: 11809538Abstract: An authentication system accesses an image of a face of a user. The face of the user is partially covered by a facial mask. The authentication system detects an area on the facial mask and generates a first identification of the user based on the area on the facial mask. The authentication system also detects an exposed area uncovered by the facial mask on the face of the user and generates a second identification of the user based on the exposed area. The authentication system compares the first identification of the user with the second identification of the user, and authenticates the user based on the comparison.Type: GrantFiled: June 21, 2022Date of Patent: November 7, 2023Assignee: Nortek Security & Control LLCInventor: Darren Learmonth

Patent number: 11790918Abstract: An audio firewall system has a microphone that generates audio data. A speech-to-text engine converts the audio data to text data. The text data is parsed for a service wake word and corresponding content data. The service wake word identifies one of a local security system and a remote assistant server. A text-to-speech engine converts the service wake word and the corresponding content data to converted audio data. The converted audio data is provided to the remote assistant server. The content data is provided to the local security system. The audio firewall system receives a response from the remote assistant server or the local security system and outputs an audio signal corresponding to the response.Type: GrantFiled: November 19, 2021Date of Patent: October 17, 2023Assignee: Nortek Security & Control LLCInventors: Philip Alan Bunker, Mayank Saxena

Patent number: 11769395Abstract: A server accesses a security system profile of a first security system. The security system profile identifies a plurality of sensors connected to the first security system. The server identifies a second security system based on at least a first sensor of the plurality of sensors coupled to the first security system. The server then generates a notification sharing profile for the first security system based on the security system profile. The notification sharing profile indicates that the second security system corresponds to the first sensor. A first event triggered by the first sensor causes a first notification to the second security system.Type: GrantFiled: July 12, 2022Date of Patent: September 26, 2023Assignee: Nortek Security & Control LLCInventors: Taufiqul Kazi, Laura Elizabeth Knight

Patent number: 11615623Abstract: Human or object presence in or absence from a field-of-view of a camera can be achieved by analyzing camera data using a processor inside of or adjacent to the camera itself. In an example, a video signal processing system receives image data from one or more cameras and uses a processing circuit to determine whether a designated object is or is not present at a particular time, during a particular interval, or over a designated sequence of frames. In an example, the designated object can include one or more of a human being, a vehicle, or a parcel. In an example, results of the determination, such as including positive human or object identification, can be used as a trigger for operation of a barrier or access door.Type: GrantFiled: June 14, 2019Date of Patent: March 28, 2023Assignee: Nortek Security & Control LLCInventors: Krishna Khadloya, Vaidhi Nathan

Patent number: 11378538Abstract: A water detection device (100) may have a water sensor on both a top and bottom of the device. A water sensor circuit (1004,1006,1100, 1101) may be configured to detect water by delivering a signal may be delivered to an electrical contact (1104, 1132), and the presence of water may be determined based upon detection of the signal at the other contact (1106, 1134). The water sensor circuit device (1101) may be configured with a comparator (1116) that uses hysteresis to provide sensitivity to the presence or absence of water. In a battery-powered water sensor, the water detection signal may be delivered as an alternating signal using, e.g., a signal modulator circuit (e.g., an oscillator circuit (1114) and gate (1120) optionally coupled to a wake-sleep controller (1112)) that is coupled to a battery (133), which may avoid oxidation or other forms of ionic corrosion. In some examples, a water detection signal may be recurrently delivered to the first contact (1132) to conserve battery power.Type: GrantFiled: September 28, 2017Date of Patent: July 5, 2022Assignee: Nortek Security & Control LLCInventors: Ming Chuan Lee, Xuefeng Ma, Jian Hua Liu, Jian Hong Yin

Patent number: 11282389Abstract: Driver and pedestrian safety can be aided by systems and methods to provide identification and classification of objects in a vehicle travel path. Information about classified objects can be shared with a human driver to inform the driver about potentially hazardous conditions, or the information can be interpreted automatically by an operating system of the vehicle. In an example, a camera coupled to a vehicle can receive images from an image sensor. A computer system can use machine learning and neural network-based processing to identify an object present in the images and determine whether the object is a pedestrian.
