An LED security light includes an LED load and a motion sensor. The LED load is activated at dusk and deactivated at dawn by a light sensing control unit. At night, the LED load is activated for performing a low level illumination. When a motion signal is detected by the motion sensor, the LED load is switched to perform a high level illumination for a short time period and then resumes to the low level illumination. The low level illumination and the high level illumination are respectively adjustable within respective designed ranges. The LED load is driven by a switching circuitry comprising a driver to output an adequate voltage with constant electric current such that a voltage V across each LED is confined in a range V.sub.th<V<V.sub.max with V.sub.th being a threshold voltage and V.sub.max being a maximum voltage avoiding damaging the LED.

Disclosed herein are system, method, and computer program product embodiments for the detection of human presence in front of a plurality of sensors such as those of speakers and a device with a processor, such as a television. Data gathered from the plurality of sensors may be analyzed by the processor to determine if one or more humans are present proximate to the device. Based on the determined presence or absence of one or more humans, further actions including, inter alia, activating a sleep mode for the one or more humans, shutting off the device in a green mode, or alerting an owner-user to the presence of an intruder can be taken.

Methods, systems and computing devices are described herein for monitoring a premises when residents or other users are present in order to detect patterns of activity at the premises. Such patterns may comprise, for example, a typical schedule indicating usage of one or more devices by one or more users of the premises. When a user is away or otherwise inactive, commands may be sent to various user devices to make it appear (e.g., to those outside the premises) as if the user is present by simulating and/or recreating the patterns that were previously detected.

A method of configuring a white LED light with a tunable diffused light color temperature, includes using a light-emitting unit configured with a first LED load emitting light with a first color temperature between 1800K and 3000K and a second LED load emitting light with a second color temperature between 4000K and 6500K, electrically connected in parallel; using a light diffuser to cover the first LED load and the second LED load to create a diffused light with a diffused light color temperature; using two semiconductor switching devices working in conjunction with a controller to respectively control a first electric power delivered to the first LED load and a second electric power delivered to the second LED load such that a total electric power of the light-emitting unit remains unchanged; and using at least one external control device to activate a selection of the diffused light color temperature.

A lamp socket assembly to be installed in a light socket and receive electrical power therefrom. The lamp socket assembly to provide electrical power to a surveillance device that detects an occurrence of a security event and notifies the lamp socket assembly of the occurrence. In response to the notification, the lamp socket assembly to turn on a light bulb.

The various implementations described herein include methods, devices, and systems for monitoring activity in a home environment. In one aspect, a method performed at a voice-assistant device includes: transitioning to operating in a second mode from a first mode; while operating in the second mode, detecting a sound; obtaining a determination as to whether the sound meets one or more monitoring criteria; and in accordance with a determination that the sound meets the one or more monitoring criteria, generating an alert or notification.

A linkable LED lighting system designed with an on line free setting method for adjusting operating parameters of at least one LED security light is disclosed. The linkable LED lighting system comprises at least one LED security light working in conjunction with a mobile phone loaded with an APP (software application) for controlling and setting at least one lighting characteristic of the at least one LED security light including time length settings, light intensity settings, color temperature settings, detection range settings, or signal frequency range or signal format settings for screening, accepting, and processing said wireless instruction signal(s) characterized with the same signal frequency range or the same signal format.

Location-Based Addressing (LBA) is a method of controlling and commissioning networked lighting devices. The lighting devices communicate over a wireless network using radio frequency communication protocols. The lighting devices are commissioned or grouped based on their 5 respective locations in a building floor plan or a building architecture. The lighting devices are commissioned to respond to radio frequency communications that correspond to their respective locations. This imposed location-based architecture reduces the amount of transmitted data required to control the lighting devices and, thus, reduces the radio bandwidth required to control the lighting devices. In other words, controlling devices “multicast” instructions and controlled devices “listen” for instructions and act only upon instructions that correspond to their respective location. Hand shaking or two-way communication between the controlling devices and the controlled devices is not required.

Methods, systems, and apparatus, including computer programs encoded on storage devices, for monitoring, security, and surveillance of a property. In one aspect, a system includes multiple robotic devices, multiple sensors, wherein the multiple sensors includes a first sensor, multiple charging stations, and a monitor control unit. The monitor control unit may include a network interface, one or more processors, and one or more storage devices that include instructions to cause the one or more processors to perform operations. The operations may include receiving data from the first sensor that is indicative of an alarm event, accessing information describing the capabilities of the each of the robotic devices, selecting a subset of robotic devices from the multiple robotic devices, and transmitting a command to each robotic device in the subset of robotic devices that instructs each respective robotic device to deploy to the location of the first sensor.
