Fleet management systems organize company vehicles, provide tracking capabilities, maintenance schedules, and fuel management. They can also track mileage and depreciation, and offer vehicle financing and marketing. The system connects to a computer installed in the vehicle and transmits information via satellite communication. A business may need a large fleet of vehicles, but it can […]
Ventilation systems control airflow in confined spaces, bringing in fresh air and channeling stale air outside. Natural systems rely on weather conditions, while mechanical systems actively regulate air quality and can include heating and cooling. Advanced systems monitor air quality and regulate particulate counts. Compliance with air quality guidelines and geographic location can influence ventilation […]
A remote keyless system allows for operation of a vehicle from a distance through a wireless transmitter. It consists of a control unit in the vehicle and a key fob with buttons for system functions. It can unlock doors, open trunks, and start the engine from a distance. It is available as an aftermarket accessory […]
Absorption systems use fluids and heat sources to create refrigeration or air conditioning without a compressor. Two types are lithium bromide/water and ammonia/water, suitable for different temperature ranges. The process involves five stages and is ideal for off-grid applications. An absorption system is a means of refrigeration or air conditioning in which cooling is achieved […]
A turnkey conveyor system is a complete package provided by a single supplier, which automates the transportation of raw materials and finished products in manufacturing industries. It increases production efficiency and reduces the need for human intervention, while also providing a single source for maintenance and troubleshooting. Many types of manufacturing industries make good use […]
Automotive navigation systems use GPS to show a vehicle’s location in real-time and provide information about travel routes and times. They can also locate nearby landmarks and provide information on traffic, parking, and speed cameras. They were once a fictional idea but became a reality in the 1990s when on-board computers had enough processing power […]
Respiratory system disorders affect breathing and can be chronic or acute. Asbestos disease, bronchitis, smoking-related conditions, adult respiratory distress syndrome, and asthma are common respiratory disorders. Symptoms include shortness of breath, coughing, and excessive mucus production. Treatment often involves antibiotics and inhalers. Smoking cessation can improve lung function. ARDS is a serious disorder that can […]
Start-stop systems in hybrid vehicles shut off the engine when the car is stopped to save fuel and reduce emissions. They use a starter generator and can be deactivated. However, hybrid vehicles have been criticized for posing a hazard to pedestrians and blind children. Hybrid vehicles designed with a start-stop system completely shut off the […]
The Hazardous Material Identification System (HMIS) uses four categories to convey safety information about materials, with higher values indicating higher risk. The categories are health hazards, flammability potential, physical hazards related to reactions to other materials, and personal protection that should be worn. The system was created by the American Coatings Association and is designed […]
A heating system is a steam or hot water system that serves multiple buildings, consisting of a boiler, pumps, valves, pipes, and fuel storage. It’s common in old college campuses, rural areas, and military complexes. Operating conditions, boiler type, and fuel source are key components. Water tube boilers are often used, and the energy source […]
Clinical data management systems are used to manage and verify data from clinical trials. They track subjects, report adverse events, and view lab test results. These systems help reduce data entry errors and keep information confidential. They also include a calendar to track the trial schedule. Clinical trials to test drugs and other treatments generate […]
Navigation systems provide graphical maps, coordinates, and directions on screens, available on computers, car stereos, and smartphones. They offer step-by-step instructions, real-time traffic information, and are integrated with businesses. Handheld portable devices are also available for outdoor enthusiasts. Many people use automated mapping software to help with directions. A navigation system is a computer program […]
Cash flow systems monitor and ensure adequate cash flow for a business. Managing cash flow is crucial for paying bills, payroll, and suppliers. A good system considers accounts receivable and payable, and saving a reserve fund. Businesses can seek help from financial advisors or software. A cash flow system is a management system that allows […]
Canada’s government is a unique blend of British and American models, with an executive branch headed by the British monarch and a system of checks and balances between the executive and legislative branches. The governor-general appoints the prime minister, and the legislative branch is bicameral. The federal judicial system oversees criminal law and maintains a […]
The suspension system of a vehicle absorbs the impact of rough roads, allowing for a comfortable and controlled ride. Early designs lacked suspension, causing discomfort and damage. Advances in technology led to the modern suspension system with shock absorbers and automatic bump damping. A vehicle’s suspension system consists of shock absorbers, springs and, if applicable, […]
A safety instrumented system uses sensors to monitor and remediate equipment. It is generally safer than relying on humans, but can be expensive. Experienced professionals are needed to read SIS values as sensors may not detect all risks. A safety instrumented system is a system in which the system, or its equipment, is monitored and […]
Ground proximity warning systems (GPWS) are carried by aircraft to prevent controlled flight into terrain accidents (CFIT). GPWS uses radar altimeters to monitor the aircraft’s altitude and detect dangerous situations, providing visual and audible warnings to the pilot. The Enhanced Ground Proximity Warning System (EGPWS) uses GPS to provide accurate terrain data beyond the range […]
Workflow management systems help streamline work processes, track employee performance, improve customer service, and increase productivity in various industries. They can also be used to identify bottlenecks and inefficiencies in production cycles. A workflow management system is a computer system designed to help create, maintain, and store information about parts of the workflow. The purpose […]
Business Intelligence (BI) software helps businesses collect, track, and display data to make informed decisions.
