      Biological Computers

      Biological computers are special types of microcomputers that are specifically designed to be used for medical applications. The biological computer is an implantable device that is mainly used for tasks like monitoring the body's activities or inducing therapeutic effects, all at the molecular or cellular level. The biological computer is made up of RNA (Ribonucleic

    • PIR Sensor

      PIR Sensor

      A PIR (Passive Infrared) sensor detects infrared light that is emitted from objects within its field of view. PIR sensors differ from other infrared sensors because they can only receive infrared waves. Because all objects emit infrared waves (electromagnetic waves that travel with heat), PIR sensors can detect objects that are in front of them.

    • Paraffinum Liquidum

      Paraffinum Liquidum

      Paraffinum Liquidum (mineral oil) is a petroleum by-product and is created through distillation. Mineral oil is completely transparent and is basically a liquid form of petroleum jelly. It is produced in large quantities and is used in many different ways all over the world, mostly due to its low toxicity and low cost. Mineral oil

    • Nanopollution

      Nanopollution

      Nanopollution refers to the waste matter or byproducts of nanoscopic device or material manufacture. Nanoscopic device or material manufacturing processes leave behind nanoparticles (smaller than a billionth of a meter) which can infiltrate the cells of humans, animals and all living organisms that may be unprepared for the influx of artificial particles. A 1941 study

    • What Are Ceramic Briquettes?

      What Are Ceramic Briquettes?

      Ceramic briquettes are special accessories for gas grills that help consume less fuel. These briquettes come in various styles and can help to give the classic grilling to meats and other dishes that are prepared over the grill. The ceramic briquettes also help to distribute the heat more evenly and this is effective in producing heat for

    • Automated Meter Reading

      Automated Meter Reading

      Automated Meter Reading (AMR) refers to the technology used for automating collection of water and energy (electricity or gas) consumption data for the purposes of real-time billing and consumption analysis. At any given time, the AMR system gathers real-time data and transfers the information gathered to the central database through networking technology. Benefits of Automated

    • How Do Inverters Work?

      How Do Inverters Work?

      Alternating current is a large part of modern society and is great for sending electricity over long distances as well as providing higher voltages to certain appliances. The problem is that batteries can only store direct current which means that some electrical sources, such as automobiles, can only support low-end, low-voltage appliances. To correct this

    • What is a Hydraulic Excavator?

      What is a Hydraulic Excavator?

      A hydraulic excavator (digger) is a large vehicle that is designed for excavation and demolition purposes. Hydraulic excavators consist of a chassis, boom, and bucket, and move via tracks or wheels. They range in size and function, an example of which is the similar but smaller “mini excavator.” All versions are generally designed for the

    • How Fiber Optic Lights Work

      How Fiber Optic Lights Work

      Fiber optic lines, which can be as thin as a piece of human hair, are made of strands of glass that are optically pure. They are used to transmit light signals, and have the ability to carry these signals over long distances. How is Light Transmitted Through Fiber Optics? The process by which light is

    • How Do Neurons Communicate?

      How Do Neurons Communicate?

      Neurons communicate by sending electrical signals throughout the body. The exact process is an electrochemical one and the speed in which neurons communicate is so fast that seeing someone drop out of someone's hand and trying to grab for it–a process that requires the image to get into the brain, processed and then a signal
