The Linked History of the Flashlight and the Battery

The Linked History of the Flashlight and the Battery The flashlight was invented in 1898 and patented in 1899. The biblical quote let there be light was on the cover of the 1899 Eveready catalog advertising the new flashlight.   Eveready Founder Conrad Hubert In 1888, a Russian immigrant  and inventor named Conrad Hubert founded the  American Electrical Novelty and Manufacturing Company (later renamed Eveready). Huberts company manufactured and  marketed battery-powered novelties. For example, neckties and flower pots that lit up. Batteries were still a novelty at that time, then only recently introduced to the consumer market. David Misell, Inventor of the Flashlight A flashlight by definition is a small, portable lamp usually powered by batteries.  While  Conrad Hubert might have known  the flashlight was a bright idea, it was not his. British inventor David Misell, who was living in New York, patented the original flashlight and sold those patent rights to the Eveready Battery Company. Conrad  Hubert first met Misell  in 1897. Impressed with his work,  Hubert  purchased all of Misells previous patents related to lighting, Misells  workshop, and his then-unfinished invention, the tubular flashlight. Misells patent was  issued on January 10,  1899.  His portable light was  designed in the now familiar tube-shape and used three D batteries  placed in a line, with a lightbulb at one end of the tube.   Success Why  was the flashlight called a flashlight? The first flashlights used batteries that did not last very long. They provided a flash of light, so to speak. However, Conrad  Hubert continued to improve his product and made the flashlight a commercial success. It helped make Hubert a  multi-millionaire, and  Eveready a huge company. Source: Utley, Bill.

Group Dynamics - Essay Example Additionally, particular reference will be paid to the Rofle reflection model theory. Within a group, the individual members always interact and continuously communicate to achieve a particular objective. The members of a group are connected by universal harmony and combined forces. Plasters, Sagull and Xiao (2003) cite that in most cases, the members of a particular group have matching abilities and rely on each other in a robust power-sharing and accountability framework. According to Duffy (2010), there are different domains in a group dynamic that emphasize on different types of teamwork skills. For example, the group dynamics in an operating room is different in some ways from that of the intensive care unit team due to the nature of work performance in the two areas. The two areas have different role team structures, time pressure, criticality, as well patient volume. Weaver et.al (2010) observes that medical care and practice is undeniably a team effort. Weaver et.al (2010) elaborates that different types of groups are important to all organizations; however, these groups should observe high standards of communication, cooperation and coordination. Well-coordinated teamwork especially in complex service areas such as the operation theater is associated with crucial patient outcomes like increased patient satisfaction while reducing nursing turnover (Machary et.al 2006). Furthermore, Weaver et.al (2010) asserts that effective teamwork is also linked with other positive outcomes such as job satisfaction and reduced stress level. Mosser and Begun (2013) are of the opinion that teamwork in the operating theater makes task performance faster because of the rapid interaction of individuals in the working the team. Subsequently, teams also enable the OR personnel to learn to provide high quality health care by working closely with each other. Within the healthcare set up, there exist four main types of
