摘要： This document describes a dual-antenna system for a video-recording doorbell and associated devices and systems. The described antenna system may be implemented on an elongated printed circuit board and can be used for wideband and ultra-wideband applications. For low-cost devices, the dual-antenna system may implement diversity antennas by including first and second substantially orthogonal antennas connected to a chipset configured for single-input single-output (SISO) functionality. The dual-antenna system described herein achieves high antenna isolation and efficiency without a decoupling structure between the first and second antennas. Further, the dual-antenna system achieves high isolation while in proximity to a battery (e.g., a battery within a housing of a battery-powered, video-recording doorbell) and a metal plate for mounting the device to a wall or other structure.

摘要： The anti-theft device for securing an electronic gadget against theft. A security sensor is attached to a rear surface of the electronic gadget. The security sensor is electrically coupled to the electronic gadget via a cable. A security software application is deployed on the electronic gadget. The security sensor is configured to transmit predefined security signal to the electronic gadget. The security application is configured to detect the predefined security signal. Responsive to detecting a security event, the security sensor stops transmitting the security signal. The security application is configured to transition the electronic gadget into an alarm state if the security application fails to receive the security signal.

摘要： Systems and methods for managing current flow in a power circuit used to dynamically share power are disclosed. A Zener diode may automatically adjust current flow in the power circuit. If the power circuit has not received sufficient current for dynamic power sharing, the Zener diode may draw additional current from a power source. An electrical current in the power circuit may be divided into a plurality of current loads. Each of the plurality of current loads may be directed through a different path in the power circuit.

摘要： A vehicle that selectively provides important sound to an occupant includes: a microphone configured to receive a noise sound; a speaker; a storage configured to store a plurality of sound waveforms and a warning sound source corresponding to each sound waveform of the plurality of sound waveforms; and a controller configured to generate a noise canceling signal based on the noise sound, control the speaker to output a noise canceling sound corresponding to the noise canceling signal, compare a waveform of the noise sound with the plurality of sound waveforms when a sound pressure level of the noise sound is greater than a threshold value, and when the waveform of the noise sound matches any sound waveform of the plurality of sound waveforms, and control the speaker to play a warning sound source corresponding to the sound waveform matching the noise sound.

摘要： A pet-activated signaling device, a pet-activated signaling system, and a method of a pet signaling a human is provided. The pet-activated signaling device includes a belt, a transducer, and multiple bells. The transducer, which emits an electromagnetic signal, and bells, which emit an audible signal, are attached to the belt. The pet-activated signaling system includes the signaling device and a receiving device which emits an alert when a signal is received from the signaling device. The method of a pet signaling a human includes pawing at the pet-activated signaling device suspended from a door handle to activate the transducer and the bells. The invention is particularly useful for use on an exterior door, allowing a dog to use a familiar method of alerting a human to open the door even if the bells are not heard by the human.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing an integrated doorbell device are disclosed. In one aspect, a method includes the actions of receiving doorbell data indicating activation of a doorbell of a property. The actions further include receiving device data from one or more devices associated with a monitoring system within the property. The actions further include determining a security status associated with the monitoring system. The actions further include based on the doorbell data indicating activation of the doorbell of the property, the device data from the one or more devices associated with the monitoring system, and the security status associated with the monitoring system, determining a response action for execution by the monitoring system. The actions further include performing, by the monitoring system, the response action.

摘要： A system and method for sampling air in a controlled environment that includes two or more air sampling devices at different locations within the controlled environment. A controller is provided at a location outside of the controlled environment and in separate air flow communication with each of the two or more air sampling devices via separate first vacuum tubes, the controller having a manifold configured to separately control a rate of air flow from the two or more air sampling devices to the controller via each of the separate first vacuum tubes and to selectively direct the air flow from each of the separate first vacuum tubes to one or more second vacuum tubes. A vacuum source is provided at a location outside the controlled environment and in air flow communication with the controller via the one or more second vacuum tubes, the vacuum source providing suction and being controlled by the controller to generate the air flow through each of the first vacuum tubes. And, a flow switch for each of the two or more air sampling devices is provided at a location between a corresponding air sampling device and the vacuum source, each of the flow switches being configured to separately measure and control the rate of air flow through a corresponding first vacuum tube. An alarm is automatically activated at a location inside the controlled environment by one or more of the flow switches when the rate of air flow measured at one or more of the flow switches deviates from a desired value by a predetermined amount.
