The resulting rigidity gives Perimeter Intrusion Detection Systems (PIDS) a stable background energy to work against. Such a structure can be used for mounting enhancements designed to impede escapes or intrusions. There are, however, advantages in making a fence less rigid. A fence that in some way reacts to an attack (an active fence) absorbs a proportion of the energy from an impact from an imparted blow, making it more difficult to penetrate. A swaying fence should also be more difficult to climb. PSDB has tested a range of active fences in non-rigid or 'floppy' form ranging from those made of glass reinforced plastic (GRP) tubes to composite fences made of chain link and mesh. These have been tested for cutting, climbing and impact attacks. Collapsing toppings have been made using shear brackets and floppy toppings made using rubber mountings. More recently, PSDB has experimented with a variety of springy toppings using the natural spring in coils of barbed wire and the inherent spring in steel bars. These have been designed with substantial overhangs to impede climbing. This paper reports the findings of tests on both floppy fences and on toppings and discusses the merits and drawbacks of this type of approach. It suggests directions in which active fence technology may be moving.","PeriodicalId":188436,"journal":{"name":"Proceedings IEEE 31st Annual 1997 International Carnahan Conference on Security Technology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126309426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some applications benefit from radio technology by minimizing setup time and reducing installation and operation costs. In recent years with the explosion in wireless communications, these radio-based security systems have become more capable while lowering costs, size, and power consumption. However, the very nature of radio communication raises issues regarding setup, operation, and security of these systems. Sandia National Laboratories, in cooperation with government and industry, has addressed many of these issues through the analysis and development of security systems, communications protocols, and operational procedures. Message encryption and frequent channel supervision are used to enhance security. Installation and maintenance of these systems are simplified by incorporating built-in radio link analysis, menu-driven configuration equipment, and other techniques. Commercial communications satellites and spread-spectrum radios are also being integrated to provide unique capabilities to the security community. The status of this work is presented herein along with details of its development. These techniques and lessons learned can be applied, in many cases, to other radio-based security systems. Realizing certain limitations, wireless communications can be utilized in a wide variety of security applications.","PeriodicalId":188436,"journal":{"name":"Proceedings IEEE 31st Annual 1997 International Carnahan Conference on Security Technology","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114454898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, the robot is used to pick and place workpieces or to transport material in a way of unmanned vehicle. This gives rise to the issue of obstacle avoidance. There are model-based and sensor-based methods for this purpose. In a model-based system, one uses artificial intelligence search algorithms to find free path in the working environment. In a sensor-based system, the sensed data is recorded in a grid map. Obstacles are represented by cells in the map. The value in the cell determines whether there exists an obstacle or not. We use the ultrasonic sensors to detect obstacles. The sensors are installed every thirty degrees at the center of robot. The surrounding information can be obtained at once. However, the poor range capability of the sensor and the shape of the obstacle may influence the performance of obstacle avoidance, we also use two CCD cameras to identify and locate target, obstacles. The pattern recognition is essentially done by the calculation. Of the first and second moment of the image. The obstacle is located by the comparison of the above calculations from two cameras. The detailed methods and experimental results will be presented with video tape.","PeriodicalId":188436,"journal":{"name":"Proceedings IEEE 31st Annual 1997 International Carnahan Conference on Security Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal imagers can provide surveillance video from security areas or perimeters both day and night without expensive security lighting. In the past, thermal imagers required cryogenic cooling to operate. The high cost and maintenance requirements restricted their use. However, recent developments in reliable, linear drive cryogenic coolers and uncooled infrared imagers have dramatically reduced the maintenance requirements and are leading to reduced system cost. These technology developments are resulting in greater accessibility and practicality for military as well as civilian security and force protection applications, This paper discusses recent advances in thermal imaging technology including uncooled and cryocooled. Applications of Forward Looking InfraRed (FLIR) systems are also discussed, including integration with a high-speed pan/tilt mount and remote control, video frame storage and recall, low-cost vehicle-mounted systems, and hand-held devices. Other facility installation topics are discussed, such as site layout, assessment ranges, imager positioning, fields-of-view, sensor and alarm reporting systems, and communications links.","PeriodicalId":188436,"journal":{"name":"Proceedings IEEE 31st Annual 1997 International Carnahan Conference on Security Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121455179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
