Laser Crowd Scanning is and amazing visual effect at most live entertainment shows, especially concerts. But, there is a bunch of safety factors that go into play before the lasers can or may be used. Some of these safety factors include, knowing where the free space is amongst the venue, understanding the angle of the beams and knowing that the safe zones aren’t amongst the areas where a person in the crowd could be in line with the beams.
Before even wasting the time and effort to setup the lasers at the venue, the people of the building should provide a layout of the venue so the crew can adjust to where they shall be able to point the beams. The crew must also make sure that they may be able to use the lasers in the venue and be aware if they can even use the laser at all where they may be travelling.
The angles of the beams are a key role in safety. When positioning the lasers the crew needs to know where the lasers are going to be placed. They should also know where the act onstage may be moving to. If the lasers are placed at a lower height, the crew should be aware of the tallest person onstage to adjust the beam angles when the laser is at such a height.
After knowing the specifications on the venue, where the laser will be positioned, knowing the safe zones where the beam will be directed to and knowing the act that’s potentially the closest to the laser. The setup may begin after all the fine details are worked out.
When setting up a laser after all the safety requirements is met the main tools that are used from a control worker to do safe crowd scanning. Knowing where the beam hits the stage at its placement, a mirror would be taped down to the stage so the beam has something to redirect off of and not harm anyone do...

... catchy to the eye like pyrotechnics. Lasers should only be used in an area that the operator feels safe to use them or as if it’s intended for a show. Crowd scanning is always the number one safety factor, think of the crows scanning safety as if it was pyrotechnics on that same stage and a performer right there. The crowd scanning is to control the safety of the fans so the operator can push the “Go Button” and not harm the crowd, whereas the pyrotechnics operator has to worry about the performers walking onto the flames. This is how crowd scanning works.

I then figured out when, what and where our lights were going to be on, off and what colour. Also sounding and V.O cues.
The pyrotechnics were gerbs. Gerbs are cylindrical devices that are designed to spray 15-foot plumes of sparks in 15 seconds. Gerbs are befitting for use indoors, as long as the appropriate precautions are taken. The pyrotechnics ignited a polyurethane (egg crate foam) material that is used for packing and product display--but not for "sound proofing," as it was used lining the stage. Considering that this foam is not intended for use as a sound treatment in buildings, it was not treated with fire retardants.

Oral and Maxillofacial surgery was the forerunner in using laser. There were attempts to replace surgical scalpel with electrocautery and later with laser. Some of the added advantages of Laser are
The first step is to decide who will attend. Knowing the number of people you will be hosting is imperative in the planning process. Someone will fail to RSVP, so always plan on an extra two to three people. Always try to give yourself at least two weeks before the event to get your final count. This time frame is important in determining table and chairs requirements or if you need to order the table and chairs from your local rental service.
The first objective was examined by taking a series of data points with the laser configured to measure flow vel...
Before the expo, sit down with your team who are entitled to attend the expo and formulate a well thought-out plan for post-show activities. This ensures that everyone is on the same page and knows what to expect, and what is expected of them upon return.
Sometimes we noticed that the light would reflect back and create a straight line (which is what we expected) but then at other times, we would notice the laser bounce around creating 3/4th of a rectangle. The laser also reflected differently depending on whether it was being shined through the curved or flat edges. The differences between the convex and the concave were also interesting to see. In the convex (or positive) simulation, we noticed the light converge or be more focused therefore making it more likely to create and image. In the concave (or negative) simulation, we noticed that the light rays were more spread out which explains why the laser beamed almost seemed thicker in that instance. Although we did not test the blue Jello, the link provided was interesting because we noticed that the red and blue Jello reacted very differently to the laser due to refraction.
Today, security is one of the most important concerns in the world. Modern technologies can serve as both weapons and protection. In the public places, such as stores and airports, companies use the machines called metal detectors. They prevent from bringing in and out objects that are not allowed. However, it creates some problems, such as false alarms and uncomfortable pat-downs, and makes this technology to be incompetent. In order to solve these problems, the scientists created new full-body scanner, which is based on the use of X-rays. The most famous one is the Backscatter scanner, which is placed in many airports. The new invention solved the problems with metal detectors and gives some more
In July of 2011, the TSA website showed that in 78 different United States airports there was 488 imaging technology (Kula). Airports have been increasing transportation security to deter terrorist attacks. After the September 11, 2011, terrorist attack, Congress passed the Transportation Security Act (TSA) to place higher security in airports. The TSA implemented body scanners in airports as one measure to raise security. The more technology advances the more advanced machines become. With the advancements in technology, TSA body scanners started using backscatter technology. Backscatter technology is an X-ray technology that is able to detect contraband which is more advanced than the regular x-ray that only detected materials due to their density. Body scanners have been a major controversy in the world today because it comes down to the issue of more security that violates one’s
Imaging Technology Scanners are used widely in the United States to filter millions of people through airport security checks, in response to terrorist threats. The systems that have generated the most controversy are the passenger full-body scanners. Two main types of full-body scanners used in airports are Backscatter and Millimeter-wave technology units (Accardo, 2014). Although they radiate different type of radiations, both scanners serve the same purpose to detect contraband concealed under clothing without the need for a strip search. Although Imaging Technology Scanners are deployed to further public safety efforts, they have also generated widespread public concerns. These concerns address public health, privacy and equity issues.
If there is anything I have learned from the research I have done on event planning is that you have
The site layout in every construction sites requiring a good planning. A proper planned site layout would definitely reduce the cost and time for construction. Before planning, there are three issues needed to be considered. The first one is identify the temporary facilities needed to support the overall site operation and all the temporary facilities are not a part of the permanent structure. The next issue is to find out the shape and the physical dimensions of those facilities. Finally, those facilities should be positioned within the site boundaries or any remote areas (Tommelein et al., 1991).
When assessing boundaries and access points, the designers should consider equipment used at the access points – the identification technology. Initially, airports used metal detectors to identif...
