The interactive whiteboard connects to your computer and a projector. With the touch of a finger, group members can interact with computer materials and their finger becomes the mouse. They can write with digital ink over anything and save their notes to a single file for easy distribution. They can wirelessly connect laptops and transfer control of the interactive whiteboard between users. Free software upgrades and an expansion slot for future hardware additions ensure that as your organization grows, the interactive whiteboard grows with you.
Put It to Work for You
How can it help your organization? That depends on what you do.
Project managers capture progress notes and track decisions, then save the notes and e-mail them to stakeholders as a progress update. Designers use it to present plans to clients and incorporate their feedback immediately, saving valuable time during the design process. Fire departments create training simulators – ensuring staff receive realistic but safe training.
No matter where you are and what you do, the interactive whiteboard can help maximize productivity.
What is a Interactive whiteboard?
Interactive whiteboard refers to electronic whiteboards which provide the facility to interact; you can touch the board to control it instead of using keyboard or mouse. It is an interactive whiteboard that is connected to a computer and a multimedia projector.Once the computer image is projected on the board you can move your finger across the whiteboard, displaying the computer image, the mouse cursor follows. You simply tap the screen twice with your finger to perform the normal double-click as you would do with your mouse.
You can control most of the computer actions from the front of the class or meeting room by just interacting on surface of the board. You can also write or draw on the whiteboard with your finger or the pens provided and save the image to the computer. These images, which are your notes from the meeting or training session, can then be printed or emailed. The software included with some interactive whiteboards also has built in Optical Character Recognition, which means you can write on the screen and the computer will recognize your hand writing and turn it into computer text.
The Interactive Whiteboard is the pen-driven interactive whiteboard. Its hard surface makes it just about unbreakable and it will take multiple users. This makes it perfect for training, group work and educational games. The DuoBoard also comes with a low-reflection screen for sensitive eyes, dual-hand operation and an electronic pen.
Sharps dispoal
Longmao 发表于 2007-07-12 16:32:08
Sharp objects, or "sharps", are used extensively throughout the AECOM Campus research laboratories. Sharps include: hypodermic needles, syringes, Pasteur pipettes, scalpel blades, suture needles, slides, coverslips, etc. Sharps can pose many serious safety risks from cuts and abrasions to the transmission of infectious diseases. These risks to workers can be eliminated through the proper use and disposal of sharps.
During recent laboratory inspections at AECOM, two serious safety hazards were observed involving the capping of syringes and the filling of sharps containers. There is no need to re-cap needles before disposal. This practice increases the risk of accidental needlesticks. To avoid this risk, place needles directly into the sharps containers after use. Do not re-cap, bend, break, clip, or remove needles from the disposable syringe.
Overflowing sharps containers are the second concern. Overflowing sharps containers can pose a risk to all workers. As a general practice, once a sharp container is 3/4 full, seal the container and have it removed by Housekeeping. Sharps containers must be closed and sealed before they can be removed from the laboratory. DO NOT ask or expect the custodial staff to handle open containers of sharps. It is the responsibility of each laboratory not to overfill sharps containers and to ensure that the sharps containers are properly sealed and can safely be transported out of the laboratory.
How tire pressure gauges work
candy 发表于 2007-07-09 11:28:32
There is a myriad of shapes, sizes, and costs to consider when shopping for a gauge, however, they all boil down to 3 basic types. The dial, digital, and stick. The gauges may look different, and display results differently, but all use the same principle. When the tire gauge is pressed onto the stem of a wheel, the air pressure in the tire pushes against some type of plunger which in turn actuates the readout section of the gauge assembly.
There are three simple steps involved in measuring a tire's pressure with a pressure gauge:
1 Get in a steady position to apply the pressure gauge to the valve stem.
2 Apply the gauge, forming a good seal between the gauge and the stem and releasing air from the tire into the gauge. Note how the pin inside the gauge presses against the valve pin inside the valve stem to release air from the tire.
3 Read the pressure from the gauge.
When the pressure gauge is applied to the valve stem of a tire, the pressurized air from the tire rushes in and pushes the piston toward the right. The distance the piston travels is relative to the pressure in the tire. The pressurized air is pushing the piston to the right, and the spring is pushing back. The gauge is designed to have some maximum pressure, and for the sake of example let's say it is 60 psi. The spring has been calibrated so that 60-psi air will move the piston to the far-right of the tube, while 30 psi moves the piston half-way along the tube, and so on. When you release the gauge from the valve stem, the flow of pressurized air stops and the spring immediately pushes the piston back to the left.
There is a calibrated rod inside the tube,to allow you to read the pressure.The calibrated rod fits inside the spring and it rides on top of the piston, but the rod and the piston are not connected and there is a fairly tight fit between the rod and the stop. When the piston moves to the right, it pushes the calibrated rod. When the pressure is released, the piston moves back to the left but the rod stays in its maximum position to allow you to read the pressure.
The way of using an oral syringe

Parents are often in the troblem of this condition, Children and babies are prescribed doses of liquid medicine which are very small or hard to measure using a normal 5ml medicine spoon. In addition, babies and small children may not be able to take the medicine from a spoon. Now we can use oral syringe to solve this problem.An oral syringeis a measuring device used to accurately measure small doses of liquid medicine, One side of the syringe is marked in teaspoons (tsp). The other side is marked in milliliters (ml). It can help you to give your child liquid medicine easily.
Syringes come in various sizes. The most common sizes are 1ml, 2.5ml and 5ml syringes, but you can get 10ml and larger syringes. Liquid medicine doses are often expressed in terms of millilitres or ml. The printed label on the bottle will provide instructions as to how much of the medicine should be given to your child.
Then how to use it? To use an oral syringe, first you should take a look at the dosage markings along the side to determine how far you'll need to fill it.Push the syringe's plunger all the way down. Then put the tip of the syringe into the medicine bottle or a small cup with some of the medicine poured into it. Slowly pull back on the plunger until the syringe fills to the appropriate mark. If you have any medicine left over in the cup, return it to the bottle.
Put the syringe into your baby's mouth and gently squirt the medicine between his tongue and the side of his mouth. This will help him swallow the medicine easily. Don't squirt it at the back of his throat — it's likely to make your baby gag.
Oral syringes, droppers, and special dosage spoons are available at almost all pharmacies and drugstores. Wash whatever you're going to use thoroughly beforehand (as you would with anything you put in your baby's mouth), and rinse it out well between doses or before administering a different medication.
Automobile History
Longmao 发表于 2007-07-04 11:15:04
The history of the automobile reflects an evolution that took place worldwide. It is estimated that over 100,000 patents created the modern automobile. However, we can point to the many firsts that occurred along the way. Starting with the first theoretical plans for a motor vehicle that had been drawn up by both Leonardo da Vinci and Isaac Newton.
In 1769, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot (1725 - 1804). Cugnot used a steam engine to power his vehicle, built under his instructions at the Paris Arsenal by mechanic Brezin. It was used by the French Army to haul artillery at a whopping speed of 2 1/2 mph on only three wheels. The vehicle had to stop every ten to fifteen minutes to build up steam power. The steam engine and boiler were separate from the rest of the vehicle and placed in the front (see engraving above). The following year (1770), Cugnot built a steam-powered tricycle that carried four passengers.
In 1771, Cugnot drove one of his road vehicles into a stone wall, making Cugnot the first person to get into a motor vehicle accident. This was the beginning of bad luck for the inventor. After one of Cugnot's patrons died and the other was exiled, the money for Cugnot's road vehicle experiments ended.
Steam engines powered cars by burning fuel that heated water in a boiler, creating steam that expanded and pushed pistons that turned the crankshaft, which then turned the wheels. During the early history of self-propelled vehicles - both road and railroad vehicles were being developed with steam engines. (Cugnot also designed two steam locomotives with engines that never worked well.) Steam engines added so much weight to a vehicle that they proved a poor design for road vehicles; however, steam engines were very successfully used in locomotives. Historians, who accept that early steam-powered road vehicles were automobiles, feel that Nicolas Cugnot was the inventor of the first automobile.
