Provided is a structure which is capable of central control of an electric device and a sensor device and a structure which can reduce power consumption of an electric device and a sensor device. A central control system includes at least a central control device, an output unit, and an electric device or a sensor device. The central control device performs arithmetic processing on information transmitted from the electric device or the sensor device and makes the output unit output information obtained by the arithmetic processing. It is possible to know the state of the electric device or the sensor device even apart from the electric device or the sensor device. The electric device or the sensor device includes a transistor which includes an activation layer using a semiconductor with the band gap wider than that of single crystal silicon.

An audio/video (A/V) recording and communication doorbell comprises a camera, a front button, and a motion sensor. The camera and the motion sensor are configured to work in tandem to detect motion in a field of view of the A/V recording and communication doorbell, such that a first one of the camera and the motion sensor detects motion and the other one of the camera and the motion sensor independently verifies the motion detection before an alert is sent to a user's client device. In this manner, user alerts from false alarm motion detections are reduced.

A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.

The present technology relates to a control apparatus, a control method, a program, and an electronic device system that enables achievement of low power consumption. The presence or absence of a preset, predetermined subject is detected from an image having a low resolution output by an image sensor in a low power consumption mode, the image sensor including, as operation modes, the low power consumption mode in which the image having the low resolution is output and a normal mode in which an image having a high resolution as compared with the image having the low resolution is output. Then, in a case where the presence of the predetermined subject is detected, the operation mode of the image sensor is set to the normal mode, and the image sensor outputs the image having the high resolution. The present technology may be applied, for example, to control of the image sensor.

An alarm system includes a latch assembly having a movable element mounted on one of an entry and a structural element, and a fixed element mounted on the other of the entry and the structural element, wherein the movable element is movable between an engaged position with the fixed element and a disengaged position from the fixed element. A magnet is provided in one of the movable element and the fixed element, and a coil is provided in the other of the moveable element and the fixed element. The magnet and the coil are positioned relative to each other so that an electric current is induced in the coil by the magnet when the movable element is moved between the engaged position and the disengaged position. An energy harvesting circuit connected to the coil converts the induced electric current into a supply voltage that powers the alarm system.

In one aspect, the self-powered sensor includes a power generation unit converting an external physical stimulus into electrical energy, and a sensing unit generating and transmitting a sensing signal corresponding to the electrical energy. The sensing unit may include an electrical energy storage unit storing the electrical energy transmitted from the power generation unit, a switching unit switching to an energized state or a power-saving state according to the comparison result of the storage amount of the electrical energy stored in the electrical energy storage unit and a reference storage amount. The sensing unit may also include a processor generating and wirelessly transmitting a sensing signal based on the electrical energy stored in the electrical energy storage unit when the switching unit switches to the energized state.

A retrofit module for lithium battery passivation, detection, activation and maintenance (PDAM) may include a test circuit, a load circuit, a microcontroller and means for electrically connecting the PDAM module to a target battery in a device. Upon power-up and/or joining or rejoining a network, and additionally at periodic intervals thereafter, the state of the target battery is determined and an activation algorithm is executed, the parameters of which are dependent upon the determined target battery state.

A method for monitoring devices based at least in part on detected conditions includes accumulating, by one or more sensory nodes, sensed information in an area that includes a controllable device. The method also includes analyzing the sensed information to identify historical information regarding the area that includes the controllable device.
