A battery isolator is an electrical device that divides direct current DC into multiple branches and only allows current in one direction in each branch. The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source e.g., an alternator without connecting the battery terminals together in parallel. This is beneficial because a weak or dead battery will drain the charge from a strong battery if both are connected directly together. The disadvantage to an isolator is added cost and complexity, and if a diode type isolator is used which is very common there is additional voltage drop in the circuit between the charging source and the batteries. Battery isolators are commonly used on recreational vehicles, boats, utility vehicles, airplanes, and large trucks where one battery is dedicated to starting and running the engine and another battery or batteries run accessory loads e.g., winches, radar, instruments, etc. . A battery isolator helps to ensure that the starting battery has sufficient power to start the engine and recharge the batteries if, for example, loads on the auxiliary battery e.g., refrigerator or navigation lights cause it to be drained, or if an auxiliary battery fails. Isolators are also used in vehicles with large, high power car stereos and off road vehicles to accommodate high current loads such as a recovery winch. .

A barrier isolator , or simply an isolator , is a device that provides a physical barrier between a laboratory technician and a work process. Isolators are routinely found within the pharmaceutical industry , and with the recent implementation of USP 797 Pharmaceutical Compounding Sterile Preparations , a set of sterile compounding standards issued by the United States Pharmacopeia , are increasingly used in pharmacy applications. They are designed to provide an isolation of a process or the maintenance of an internal condition e.g., Asepsis sterile or aseptic . Isolators may operate at positive, negative, or ambient differential atmospheric pressure pressure . Isolators may provide personnel, product, or environmental protection, or any combination thereof. They are used throughout industry, from orange juice filling lines to cytotoxicity cytotoxic drug compounding to electronics manufacturing. Regarding pharmacy applications, because people are the greatest source of contamination during aseptic manufacturing of drugs, reducing personnel interventions into the process zone has significant impact on the efficacy of the final drug product. In the mid 1980s, the industry began to employ barrier isolators, and later, in the 1990s, Restricted Access Barrier System s, or RABS, to separate people from the process. The acronym RABS was coined by Stewart Davenport of Upjohn now Pfizer . Since that time, the technology and applications of these systems has developed and broadened significantly. Major manufacturers of barrier isolators include http www.getinge.com GETINGE , http www.envair.co.uk Envair Limited , http www.machaire.co.uk Mach Aire Ltd , http www.walkerbarrier.com Walker Barrier Systems , http www.howorthgroup.com Howorth Air Technology , http www.amercare.co.uk Amercare Ltd , The Baker Company, Esco Global, and Thermo Electron Corporation.

These elements are insulation material, their structure, and data transfer method. Designers incorporate isolation because of safety regulations ref http www.qmed.com white paper digital isolator simplifies usb isolation medical and industrial applications ref or to reduce noise from Ground loop electricity ground loops , etc. Galvanic isolation ensures data transfer without an electrical connection or leakage path that might create a safety hazard. Yet, isolation imposes constraints such as delays, power consumption , cost and size. A digital isolator s goal is to meet safety requirements while minimizing incurred penalties. Optocoupler s, a traditional isolator, incur the greatest penalties, consuming high levels of power and limiting data rate s to below 1 Mbit s. More power efficient and higher speed optocouplers are available but impose a higher cost penalty. Digital isolators were introduced over 10 years ago ref http www.analog.com optocoupler ref to reduce penalties associated with optocouplers. They use CMOS based circuitry and offer significant cost and power savings while significantly improving data rates. They are defined by the elements noted above.

Unreferenced stub auto yes date December 2009 File Optical Circulator symbol.jpg thumb Optical Circulator symbol An optical circulator is a special optical fiber fiber optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber , analogous to the operation of an electronic circulator . An optical circulator is a three port device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1, but instead exits from port 3. Circulators can be used to achieve bi directional transmission over a single fiber. Because of its high opticalisolator isolation of the input and reflected optical powers and its low insertion loss , optical circulators are widely used in advanced fiber optic communications communication systems and fiber optic sensor applications. Optical circulators are non reciprocal optics, which means that changes in the properties of light passing through the device are not reversed when the light passes through in the opposite direction. This can only happen when the symmetry of the system is broken, for example by an external magnetic field . A Faraday rotator is another example of a non reciprocal optical device.

Optical engineering is the field of study that focuses on applications of optics . Optical engineers design components of optical instrument s such as lens optics lenses , microscope s, telescope s, and other equipment that utilizes the properties of light . Other devices include optical sensors and measurement systems, laser s, fiber optic communication systems, optical disc systems e.g. CD , DVD , etc. Because optical engineers want to design and build devices that make light do something useful, they must understand and apply the science of optics in substantial detail, in order to know what is physically possible to achieve physics and chemistry . However, they also must know what is practical in terms of available technology, materials, costs, design methods, etc. As with other fields of engineering, computer s are important to many perhaps most optical engineers. They are used with instruments, for simulation, in design, and for many other applications. Engineers often use general computer tools such as spreadsheet s and programming language s, and they make frequent use of specialized optical software designed specifically for their field. Optical engineering metrology uses optical methods to measure micro vibrations with instruments like the laser speckle interferometer or to measure the properties of the various masses with instruments measuring refraction .

Image Optical Interleaver.gif thumb 400px right Illustration of the function of an optical interleaver and de interleaver An optical interleaver is a 3 port passive fiber optics fiber optic device that is used to combine two sets of dense wavelength division multiplexing DWDM channels odd and even channels into a composite signal stream in an interleaving way. For example, optical interleaver takes two multiplexed signals with 100 GHz spacing and interleaves them, creating a denser DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25 GHz or 12.5 GHz spacing. The device can be used in a reverse direction, forming an optical deinterleaver that separates a denser DWDM signal into odd channels and even channels. See schematic diagram. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. Thus, optical interleaver can expand the number of channels per fiber, and devices and or networks can be upgraded without requiring that all devices be upgraded. Optical interleaver is based on multiple beam interference . Currently, there are two approaches to building optical interleaver 1 Step phase Michelson interferometer , and 2 birefringence Birefringent crystal networks. The former is based on Michelson interferometer combined with Gires Tournois interferometer .
