“…Encryption and acoustic surveillance are closely related, since encryption is one of the principal ways in which the privacy of communications is safeguarded. For this reason, acoustic surveillance, computer encryption, and cryptology share a common history in many respects [22].…”

Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people and events for the purpose of influencing, managing, directing, or protecting them. In this paper, an audio surveillance system was designed, simulated and constructed by replacing discrete components with an integrated circuit(CD2003) with the view of taking advantage of electret microphone ability to capture sound of low frequency and transmit it to the receiver where the signal can be retrieved. The audio signal was then amplified using two bipolar junction transistors (BJT), modulated and transmitted via an antenna. A provision for recording of the retrieved signal was made using a telephone set for continual logs of information for retrieval purposes at the receiver section. The circuit was designed and fully implemented with a designed output power of 0.3watts which transmitted within 8-12meters radius and waveforms from proteus 8 professional and multism software were obtained and compared for performance and evaluation. This short range of coverage was designed and implemented with the aim of avoiding major interference from the surrounding since the system is meant to survey a small area like banking hall, bulk cash rooms and other sensitive areas.

“…There are many systems rely on the combination of sensors and internet for home security, Zhang et al [2] proposed an indoor security system based on a combination of sensor nodes with ZigBee connected with jumping robot. The sensor nodes are installed above the doors and windows at the house to detect an intruder, then send a message to the robot; the robot can jump to take a photo and send it to the gateway.…”

Abstract-In this paper, we design a device-free intruder detection and alarm system, named WiGarde by exploiting off-the-shelf Wi-Fi channel state information (CSI) to detect an intruder through door or window. WiGarde extracts the CSI amplitude information across MIMO antennas. We implemented WiGarde with commercial IEEE 802.11 NICs and evaluated its performance in two cluttered indoor environments. The system is robust and avoids false alarm occurrence, owing to our novel bad stream elimination algorithm. To extract the best feature, we design a new method to intercept the segment of the signal of intrusion based on wavelet analysis and dynamic time window based on Short-time Energy. We adopt Support Vector Machine (SVM) algorithm to classify human intrusion; our SVM algorithm could classify intrusion process with general walking through the area of interest. We compare WiGarde with the previous approaches; results show that our system outperforms the corresponding best CSI-based and RSSI-based in both of static and motion states. Our system gained high accuracy of 94.5% in a dynamic environment for intrusion through door or window.

“…In a manner similar to linear springs, torsional springs can be used in a linkage mechanism to store energy which is released suddenly to initiate a jump [14], [15], [16]. Using this strategy can result in massive power amplification, allowing for very impressive 2014 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2014) September 14-18, 2014, Chicago, IL, USA jumps [17].…”

Locomoting soft robots typically walk or crawl slowly relative to their rigid counterparts. In order to execute agile behaviors such as jumping, rapid actuation modes are required. Here we present an untethered soft-bodied robot that uses a combination of pneumatic and explosive actuators to execute directional jumping maneuvers. This robot can autonomously jump up to 0.6 meters laterally with an apex of up to 0.6 meters (7.5 times it's body height) and can achieve targeted jumping onto an object. The robot is able to execute these directed jumps while carrying the required fuel, pneumatics, control electronics, and battery. We also present a thermodynamic model for the combustion of butane used to power jumping, and calculate the theoretical maximum work output for the design. From experimental results, we find the mechanical efficiency of this prototype to be 0.8%.
