Mobile Robot, Explore Unknown Map with Obstacles, Gas Detection, V- rep, Khepera III, Albers Algorithm. Abstract: Nowadays, using robots instead of humans in risk operations is an interesting point in the field of robotics. In this paper we introduce an integrated approach for search and rescue operation of detecting gas sources in large areas; e.g. houses, factories, and labs. This aims at saving people’s lives at bottlenecks resulting from gas leak and ignition of fires. Experiment is performed

One of the main challenges in this effort is how to autonomously operate multiple sensors for oxygen monitoring and to replace the existing technology which is based on a handheld portable gas detector weighting up to 5lbs and placed in the belt or waistband of the worker. Our innovative design is based on converting wasted mechanical energy from the movement of the worker to useful amount of energy by using the piezoelectric transduction mechanism. Depending on the movement of the worker and the

smoke detectors. The main cargo compartment had 7 smoke detectors installed, and in the 4 lower cargo compartments were 19 smoke detectors installed. During the preflight checks the flight crew tested the operation of the smoke detectors by enabling their test function from the cockpit. The flight engineer reported that no problems were encountered during the functional check of the smoke detectors before the flight. The main cargo compartment smoke detector system consists of detectors located

The condenser fan helps cool it. The refrigerant is then forced through a thin tube, or capillary tube, and as it escapes this restraint and is sucked back into a gas again, absorbing some heat from the food storage compartment while it does so. The evaporator fan distributes the chilled air. In a self-defrosting refrigerator/freezer model, moisture condenses into frost on the cold evaporator coils. The frost melts

reached above 70 ppm. During further investigation, firefighters discovered that a malfunctioning furnace was the culprit for the higher levels of CO. To make matters worse, the carbon monoxide detector had the battery removed, which could have proven a fatal mistake if the neighboring apartment had not had a detector that triggered the alarm. It alerted everyone within that building that high

BACKGROUND INFORMATION Airport security is currently seen as one of the biggest inconveniences attributed to travel. However a brief look back in history to some of the conditions frequent flyers were subjected to makes modern air travel look like a breeze. Some of the earliest attempts at flying required an excess of manpower. Leonardo da Vinci is credited to be the first to design basic flying machines called ornithopters, that gave man mechanical wings. Through a system of pulleys the wings could

Security and Loss Prevention Plan Ramona Jalba Security and Loss Prevention • Initial concerns and concepts relating to security: 1. Recent history; 2. General areas the program will consider; 3. Legal requirements associated with protecting guests and property; 4. Elements involved in setting up a security and loss prevention program. Security and Loss Prevention • Security equipment and procedures as they relate to physical security, internal control and the overall protection of guests

research the project is built to detect LPG gas and other combustion gas in the kitchen restaurant. Most of restaurant owner and worker use traditional method to detect a gas leakage. Therefore, as a human being, there are limitations to detect those poisonous gases as some of them are colorless and odourless compound. In this chapter, the basic flow of project and approach for the project will explain in detail in the subsection of this chapter. This gas alerting system is divided into two parts
