Initially, mattresses were made of feather, hair, and straw. Mattresses have evolved over the years and are now made using innersprings, latex, flexible polyurethane foams, and other products. In the last 10-15 years, there has been a drastic shift in awareness of mattresses, which has resulted in a shift in buying behavior.

The Construction Equipment market has experienced several pitfalls in the past decade because of the global economic recession. The Crane market forms an integral part of the Construction Equipment market and has co-witnessed the market falls. There are broadly three types of cranes: mobile cranes, marine and port cranes, and fixed cranes. Cranes can be categorized as per their load lifting capacity, lift height, and outreach. The Global Crane market is currently undergoing a radical change, fueled by the growth of emerging economies, exponential growth of the Infrastructure industry, and drive toward greater energy efficiency.

CO2 lasers use gas as the active laser medium. CO2 lasers are preferred over other lasers such as excimer lasers because they are more reliable, efficient, robust, and easier to operate. They are used for cutting and welding in industries such as Manufacturing, Automotive, Electronics, Healthcare, and Telecommunication. Their superior performance, compact size, high output power, and durability make them the most prominent among all the gas lasers developed.

LAB is a colorless detergent alkylate produced from kerosene feedstock. It is produced as an intermediate chemical while manufacturing certain surfactants. It is an organic compound having good optical transparency and high light yield. LAB is mainly used in the production of LAS and for niche applications such as agricultural herbicides, ink solvents, paints, and electric cable oil. LAB also finds usage in neutrino detectors as a liquid scintillator.

Breath analyzers are devices used to detect the presence of different compounds in an individual's breath sample. Breath analyzers are most commonly used to measure the blood alcohol content in a breath sample. These devices are a major tool in convicting offenders of drink and drive offenses. Other applications of breath analyzers include identifying drug abuse and detecting diseases such as asthma and tuberculosis.

A drive is an adjustable speed device that regulates the speed and direction of motors. Adjustment is done by varying the current flow through the motor. Drives are classified into two broad categories based on the type of current: AC drives and DC drives. AC drives are used to control AC electric motors, while DC drives are used for DC electric motors. Drives are widely used in manufacturing industries to regulate and control electrical devices such as fans,conveyors, machine spindles, and pumps. AC drives are widely used in process industries to increase the energy efficiency of motors.

At the end of 2012, U.S. wind turbines in distributed applications reached a 10-year cumulative installed capacity of more than 812 MW from more than 69,000 units across all 50 states. In 2012 alone, nearly 3,800 wind turbines totaling 175 MW of distributed wind capacity were documented in 40 states and in the U.S. Virgin Islands, with 138 MW using utility-scale turbines (i.e., greater than 1 MW in size), 19 MW using mid-size turbines (i.e., 101 kW to 1 MW in size), and 18.4 MW using small turbines (i.e., up through 100 kW in size).

In light of rising motorization, transportation planners have increasingly supported alternatives to the indiscriminate use of the car. Off-street parking policy and carsharing have emerged as credible alternatives for discouraging car ownership. This report explores an initiative that could connect these policy fields and build on their synergy: the provision of on-site carsharing service in residential developments. It evaluates the performance of on-site carsharing programs in the San Francisco Bay Area by interviewing developers, planners, and carsharing service providers. Interviews were conducted in four Bay Area cities that support the provision of carsharing as an alternative to the private automobile. Based on these interviews, this report identifies the principal factors contributing to the success or failure of on-site carsharing: the unbundling status of off-street parking in residential developments; ties to off-street parking standards; financial constraints; and the level of coordination among stakeholders. The interviews revealed that on-site carsharing has been accepted by developers, planners, and service providers, particularly in densely-populated, transit-rich communities. Nevertheless, there appears to be a gap between on-site carsharing programs and off-street parking standards, and between carsharing programs and carsharing business operations. The authors recommend that a few models for establishing carsharing policy be tested: a model designed to serve high-density cities with traditional carsharing; and another designed to serve moderately-dense communities, with new carsharing options (e.g., peer-to-peer). In the case of the latter, trip reduction can be achieved through the promotion of alternative modes along major corridors.
