Jobsite Cameras Past, Present, Future
Jobsite Cameras Past, Present, Future How jobsite cameras are evolving in use and capability By David Gaw, Founder, CEO – Sensera Systems Jobsite cameras have become an essential tool for the modern connected jobsite. Understanding these systems and how they support construction best practices is important in today’s ever-expanding jobsite technology array. In this article, we’ll take a look at the evolution of jobsite cameras and how they are impacting the construction industry. WHAT IS A ‘JOBSITE CAMERA’? A jobsite camera is simply a camera that is used on a construction site to provide automated capture of imagery and/or video. Most would also agree that a jobsite camera is one that is network connected to allow for remote viewing and image retrieval. However, there are some more basic devices used on jobsites that record images and video to local storage for periodic manual retrieval by the user. For the purposes of our discussion here we will consider only network-connected cameras, since non-connected cameras are typically not suitable for commercial construction project applications. In addition to the camera hardware itself, a ‘jobsite camera’ typically also incorporates software that provides the following basic functions (at minimum): • Remote configuration of the camera operation • Viewing of images and video • Remote long-term storage of images and video (e.g., cloud-based storage) • Creation of time-lapse videos from individual still images collected at specified intervals BACK IN THE DAY The initial jobsite cameras grew out of early ‘webcam’ applications. A webcam is a camera that is connected to the Internet (or the Web), to allow for remote real-time viewing. -
Estimating Your Air Consumption
10/29/2019 Alert Diver | Estimating Your Air Consumption Estimating Your Air Consumption Advanced Diving Public Safety Diving By Mike Ange Mastering Neutral Buoyancy and Trim Military Diving Technical Diving Scientific Diving and Safety Program Oversight Seeing the Reef in a New Light ADVERTISEMENT Do you have enough breathing gas to complete the next dive? Here's how to find out. It is a warm clear day, and the Atlantic Ocean is like glass. As you drop into the water for a dive on North Carolina's famous U-352 wreck, you can see that the :: captain has hooked the wreck very near the stern. It is your plan to circumnavigate the entire structure and get that perfect photograph near the exposed bow torpedo tube. You descend to slightly below 100 feet, reach the structure and take off toward the bow. Unfortunately, you are only halfway, just approaching the conning tower, when your buddy signals that he is running low on air. Putting safety first, you return with him to the ascent line — cursing the lost opportunity and vowing to find a new buddy. If you've ever experienced the disappointment of ending a dive too soon for lack of breathing gas or, worse, had to make a hurried ascent because you ran out of air, it may surprise you to learn that your predicament was entirely predictable. With a little planning and some basic calculations, you can estimate how much breathing gas you will need to complete a dive and then take steps to ensure an adequate supply. It's a process that technical divers live by and one that can also be applied to basic open-water diving. -

Digital Camera Fully Compatible, Newly Developed S-TTL System
Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera. INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control. Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure. When we start with the history of underwater TTL auto strobe, underwater camera "NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera / housing). A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly NIKONOS type 5 pin electrical wired, automatic TTL flash control is usable with any TTL auto strobe sync connector and NIKONOS V like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync with INON Z-22 strobe cable. Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. -
Now I Know Better
Now I Know Better BY CATHY CHURCH never earned my dive instructor certification because •1 I’ve only ever wanted to teach photography, not scuba. I am, however, a Professional Association of Diving J Instructors (PADI) limited field specialty instructor. To be that, I needed to be a divemaster, which meant I had get my rescue certification. Rescue was a class I very much wanted to do anyway, even though I had taken it unofficially many, many years ago and have actually rescued several divers in my 45 years of diving. THE EVENT I had a student who wanted to take an underwater photo class with me on my private photo boat, and she brought her son along. The son was a certified diver, but I knew that neither I nor his mother would be able to pay much attention to him while we were engaged in the photography class. So I assigned a dive instructor from my staff to be his buddy. Toward the end of our dive I looked down and saw the son was deeper than we were. Since we were close to our time limit, I became concerned about the possibility he and the instructor were too deep and had been down too long. I got the instructor’s attention and vehemently indicated that he should get the son back to the line for ascent. I turned to my student and started toward the mooring Don’t be complacent or rely too heavily on other divers’ skills. Lean line. I looked back just in time to watch her son do a rapid, administer oxygen and basic first aid. -

<P>The Texas Education Agency (TEA) Proposes the Repeal of <*>100
The State Board of Education (SBOE) adopts the repeal of §§130.13, 130.14, and 130.308-130.310 and new §§130.123-130.127, 130.315-130.318, 130.420-130.435, and 130.485-130.491, concerning Texas Essential Knowledge and Skills (TEKS) for career and technical education (CTE). The repeals and new sections are adopted without changes to the proposed text as published in the March 6, 2020 issue of the Texas Register (45 TexReg 1551) and will not be republished. The adopted repeals and new sections update the TEKS to align with recent legislation requiring the board to consolidate high school technology applications TEKS into CTE TEKS and eliminate TEKS for duplicative courses. The new sections also update the TEKS for CTE to add a new career cluster in energy to align with revised programs of study. REASONED JUSTIFICATION: The 86th Texas Legislature, 2019, passed House Bill 963, which required the SBOE, not later than March 1, 2020, to conduct a review of the TEKS for CTE and technology applications courses for Grades 9-12 and amend the board's rules to consolidate courses and eliminate duplicative courses. The SBOE is only required to implement this provision if the legislature appropriated money specifically for that purpose. If the legislature did not appropriate money specifically for that purpose, the SBOE may, but is not required to, implement a requirement using other appropriations available for that purpose. The legislature did not appropriate money specifically for the purpose of implementing this requirement. Texas is redesigning state-level programs of study to include coherent and rigorous content with challenging academic standards and relevant career and technical content.
