BryteWerks Announces Its New Line of Intelligent High-Def Digital Projectors

Tech start-up BryteWerks LLC announces the launch of a product line poised to establish a new category of intelligent, hybrid media centers based on an advanced high-definition digital projector platform. The BryteWerks Model One line of Intel Core CPU-based digital projectors merge state-of-the-industry computer, digital, and optical technologies with superior connectivity capabilities and innovative industrial design into a cost-effective and intuitive multimedia control and exhibition powerhouse.

Designed for either consumer or professional applications, the BryteWerks Model One line delivers exhibition-quality 16:10 widescreen 1920x1200 resolution , through a LCD Native WUXGA panel. The projectors also feature an ultra-high brightness of 6,000 - 11,000 lumens, a 1000:1 True Contrast Ratio, and a 1:1 throw of 1 foot to 50 feet, making them the very best, all-purpose digital projectors in their class. Internally, the BryteWerks Model One projectors feature , a fully-integrated Intel Core i3 to i7 HTPC CPU, a full featured, slot-loaded Blu-ray player, up to 2 terabytes of internal storage, including a 500 gigabyte Solid State Drive, unequaled connectivity options, and a custom version of XBMC, an open source media organization and playback application, making the Model One a revolutionary and unsurpassed media center.

Ease-of-operation in any application was paramount in the design criteria for the BryteWerks Model One. Highly intuitive and non-linear system and content management (including the ability to operate numerous BryteWerks projectors and connected devices simultaneously), is controlled from the 720p 8.9-inch touch panel display on the back of the projector, a provided RF remote control, or the free XBMC remote app for Android and iOS devices, as well as existing Wifi & Bluetooth devices – from keyboards to smartphones to tablets - already on the market.

The BryteWerks Model One Projector offers the ability to build a professional cinema experience effortlessly, seamlessly and transparently in any environment or application without playback interruption. Operational features, to name only a few, include customized media playlist creation, variable frame rate control up to 60 fps, pre-rendered transitions, and independent control of ‘connected devices’ and/or daisy-chained BryteWerks projectors (or a combination of the two). Professional post-production applications include editing, visual effects creation and color grading. The open-source Python-based XBMC offers infinite feature and plug-in development allowing users infinite customization options.

Connectivity via 802.11n Wifi, Bluetooth and gigabit Ethernet provides seamless two-way communication with other BryteWerks projectors, as well as a wide variety of other peripherals, including, but not limited to, gaming devices, flatscreen displays, external hard drives, computers, handheld smart devices, and digital video and signal processing and routing equipment. The unique power and I/O interface, which also features dual USB and HDMI ports, 5.1 individual analog surround sound outputs and AC power, is a fully-upgradeable, patent-pending cable management system that conceals all cable interfaces in the projector's Mag-Snap feet.

The ultra-wide 105 mm adjustable prime lens provides greater picture fidelity and a brighter image with less optical distortion. The 1:1 Lens Throw Ratio eliminates the need for a lens throw calculator, thereby reducing set-up time in both an Imperial and Metric environment. Aftermarket lenses can adjust the projector’s throw to any size screen in any size room or theater. Optical Keystone Correction of +/- 20 degrees vertical is distortion-free with no interpolated or cropped pixels - common with digital keystone correction – and provides a more accurate picture.

The open source, industry standard Metal Halide lamp allows the user the choice of replacement bulbs from multiple inexpensive vendors, thereby reducing long term operating costs. Bulb replacement is fast and easy, without the need for tools, by simply releasing the Model One’s magnetically-latched lid and unscrewing the bulb from the projector’s light engine.

The Model One uses the BryteWerks proprietary AirHeart airflow management system consisting of multiple chambers with discreet fans and plenums that result in superior cooling at an ultra quiet operating noise level as low as 27dB .

The sleek and sophisticated black aluminum and steel enclosure, built on a robust aluminum chassis, is only 17-inches cubed, weighs only 28 pounds, and is devoid of mechanical buttons. In addition, the forward compatibility design criteria allows for simple and inexpensive future data and power management upgrades, resulting in a long and low-cost operational lifespan. The BryteWerks Model One product line is backed by a standard 1-year warranty against manufacturer’s defects, which can be upgraded to an unlimited 3-year warranty.

The BryteWerks Model One is a dazzling and sophisticated centerpiece for a home theater as well as a rugged, if not bulletproof, ultra-reliable tool in a performing arts center, museum, church, indie film theater, corporate boardroom, military applications or AV rental inventory.

Projector Lamps

Projector lamps are used as the light source in projecting devices. For example; a movie projector is a device for displaying moving pictures, and this is achieved by projecting  them onto a large screen which is usually set at some given distance from the movie projector. These types of projectors are known as opto-mechanical devices.

A projector lamp has a wide range of applications, not only used for presentations in business units and educational institutions, but also it can use in movie or home theaters.

Projector lamps are classified into three types, namely overhead, slide, and multimedia Projector lamps. To day, there are many different types of devices and projectors which most of them will usually require some type of light source.

The size and shape of projector lamps and bulbs vary enormously due to the huge range and types of projecting equipment that is available in the market today. A bulb that is suited to the old type movie projector will be very different from the lamps that are required to fit into a rear television television and they have a very different  function.

The lamps may be installed by a specialist or in many cases installed by the projector owner or operator. While placing a lamp or bulb, make sure the screws or bolts of the terminals are not too tight as theses can break the ceramic part and damage the isolation of the lamp. However if they are not tight enough, they can cause too big a charge on the ballast causing it to break.

Always make sure the bulb is well housed in its cartridge. There may be a tendency to stop at the first sign of resistance. Continue applying pressure on the base of the bulb until it is well fixed within the cartridge.

Whatever the type of projector lamps that you used, after a certain point of time it will start to dim and die out and it is time to replace with the new one.

Solar shines on East Lycoming School District

HUGHESVILLE - Earlier this year the task of installing approximately 2500 solar cell panels became part of an energy performance project through PP&L's Renewable Energy contract authorized by the state of Pennsylvania. Installed by Millenium Construction from Connecticut, the energy project took until mid-March to be completed. PP&L will guarantee its performance over a period of time according to David Maciejewski, East Lycoming School District's Business Manager. Currently the solar field will supply fifty percent of the school district's electric power over a course of one year. "This is a huge savings. The solar system will generate a savings of $150,000 over the year to offset expenses. It has a payback of 9.1 years," said Maciejewski.

One of the largest so far in Lycoming County, the project sits on approximately three acres of school property sandwiched between hybrid willows and the Hughesville Borough Water Authority's well field. Comprised of several individual solar cells, the panels collect solar radiation from the sun and actively convert that energy to electricity.

Solar field possibilities came when a million dollar grant was offered from the Commonwealth Financing Authority through a grant awarded in 2010. The entire project totaled 3.9 million dollars. PP&L contributed 1.4 million and East Lycoming School District paid 2.5 million with one million of it coming from the American Recovery Reinvestment Act, a one time federal fund.

Mr. William Carroll Industrial Arts teacher at Hughesville High School is teaching two sections in alternative energy courses for both juniors and seniors. Currently 50 students are enrolled in the science curriculum and are learning not only about the solar panels, but other sources of alternative energy. "It is an exploratory course with hands-on applications of all energy sources with segments on both traditional and alternative," said Carroll.

"The life expectancy for these panels is 25 years with a performance guarantee based on a 15 year life span," Maciejewski said. After about 25 years, the solar panels do decrease in deficiency. "Twenty-five years from now they will still be functioning, but will produce less electricity for the district," he added. "After that panels will remain in place, but will change some out to be more efficient."

PP&L will be servicing the equipment over the course of time and the school district will maintain the property.
