摘要:
An electrical control system including a plurality of electrical devices communicates over a network and interfaces and works with non-protocol devices and signals that only send/receive an on/off digital signal or send/receive one of numerous analog signals. The devices communicate with one another over a network implemented using different types of media. The system includes the necessary user interfaces, network management system interfaces and displays to provision, administer, operate and maintain the electrical device network. The system is particularly suited for lighting control applications to control the lights and/or other electrical loads within an office, building, room or home by motion detection, ambient light sensing, switching functions, dimming functions, temperature sensing functions and humidity sensing functions. Most devices are equipped to put the device in an ON, OFF, or AUTO mode.
摘要:
A multifunction sensor device which provides various transducer functions including means for performing temperature sensing, ambient light sensing, motion detection, switching functions and a means to put the device in an on, off or auto mode. The device has utility in environments such as that found in offices, schools, homes, industrial plants or any other type of automated facility in which sensors are utilized for energy monitoring and control, end user convenience or HVAC control. Key elements of the invention include overcoming the difficulty of mounting diverse sensors or transducers within the same device or housing; permitting these various sensors to exist in a single package that can be mounted to a wall in a substantially flush manner; and eliminating the requirement of an air flow channel in the device, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis. The device may include additional transducers or sensors and is constructed such that the temperature sensor is neither exposed to the flow of air in a room or area nor in an airflow channel whereby a chimney effect may occur. The device has a passive alcove or cavity that acclimates to the ambient air temperature through the process of diffusion. The device can transmit and receive real time data, relative data and actual discrete data in addition to switching and controlling loads locally or remotely.

The resistive sensor consists of a pair of electrodes separated by an impervious insulating material. The sensor is mounted adjacent to an exhaust port of an airgun, in the path of the air blast that results when the gun is fired. When the air gun is submerged and not activated, the surrounding water creates a low-resistance path between the electrodes. When the gun is fired, the air blast blows the water away from the electrodes and the resistance between them abruptly increases substantially. A bridge circuit detects the instant of resistance change and generates an electrical transient to mark the time that the gun fired.

The present invention relates to a family of resettable circuit interrupting devices that avoid reverse wiring conditions by sensing which pair of two pairs of terminals on the circuit interrupting device is connected to a source of electricity and connecting the pair of terminals sensed as line terminals to the circuit interrupting device as the line terminals and the other pair of terminals as the load terminals.

A multifunction sensor device acts as a heat detector and performs various transducer functions for temperature sensing, ambient light sensing, motion detection, switching functions, and a mechanism to put the device in an on, off or auto mode.

Key elements include overcoming the difficulty of mounting diverse sensors or transducers within the same device or housing; permitting these various sensors to exist in a single package mounted to a wall; and eliminating the requirement of an air flow channel, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis.
