A sensor array is a group of sensors, usually deployed in a certain geometry pattern, used for collecting and processing electromagnetic or acoustic signals. The advantage of using a sensor array over using a single sensor lies in the fact that an array adds new dimensions to the observation, helping to estimate more parameters and improve the estimation performance. For example an array of radio antenna elements used for beamforming can increase antenna gain in the direction of the signal while decreasing the gain in other directions, i.e., increasing signal-to-noise ratio (SNR) by amplifying the signal coherently. Another example of sensor array application is to estimate the direction of arrival of impinging electromagnetic waves. The related processing method is called array signal processing. Application examples of array signal processing include radar/sonar, wireless communications, seismology, machine condition monitoring, astronomical observations fault diagnosis, etc.

Entertainment device configured for interactive detection and security vigilant monitoring in communication with a control server

Home security detectors configured with the control components of the home comprising interactive detectors enhanced to support location-awareness and home occupant-awareness and functionality. The system includes at least one motion sensor configured with communication devices operatively arranged to transmit information about any motion of occupants in the various sections of the home as part of the information about the occupancy of the home during an emergency. At least one sensor is provided in various rooms of a home each sensing a state of the home. A central communication device is coupled, wired or wirelessly, directly or indirectly, to each home sensor configured to transmit the state of the home. The number of occupants in the home are determined by at least one body heat sensor and at least one heartbeat sensor each configured with the interactive detectors to detect the presence of emergency and home occupants and to know the present situations such as their heartbeats, such that the number of occupants and their locations are determinable from the number of detected body heat and their security and safety conditions are determinable by their heartbeats. The detection method includes the steps of sensing a state of the home and transmitting the state of the home to at least a server. Images of the home are captured by at least a camera means configured with at least a MOS and/or CMOS based active sensor array for producing real-time images and stored in the server for wireless retrieval. The images ideally include at least an intruder of the home. The server is configured with a central processor for enabling controlling security vigilance monitoring and for enabling rapid distribution of detection data, voice, and other detection signals within the monitoring environment. The system establishes a network which includes configuring home audio/visual devices, media destination means such as televisions, monitors, PDAs, notepads, notebooks, MP3, wireless stereo, cell phones etc for the detection means. The control server supports video/audio servings, telephony, messaging, file sharing, internetworking, and security monitoring and allows home occupants to access and control the home network environment from any location within a controlled residential, commercial/industrial and/or non-residential, commercial/industrial environment with at least a computer means such as a cell phone.
