![]() ![]() #DISK ARBITRATOR TO KEEP DISKS MOUNTING SERIAL#At 320 MHz x 16 bits there is a theoretical maximum peak data rate of 640 MB/s.ĭue to the technical constraints of a parallel bus system, SCSI has since evolved into faster serial interfaces, mainly Serial Attached SCSI and Fibre Channel. Subsequent extensions to the SCSI standard allowed for faster speeds: 20 MHz, 40 MHz, 80 MHz, 160 MHz and finally 320 MHz. The 16-bit option became the most popular.Īt 10 MHz with a bus width of 16 bits it is possible to achieve a data rate of 20 MB/s. The SCSI-2 standard allowed for faster operation (10 MHz) and wider buses (16-bit or 32-bit). The original SCSI-1 version of the parallel bus was 8 bits wide (plus a ninth parity bit). The SCSI-3 standard then split the framework into separate layers which allowed the introduction of other data interfaces beyond parallel SCSI. The first two formal SCSI standards, SCSI-1 and SCSI-2, described parallel SCSI. 8.2 Mixing single ended and low voltage differential.Starting with SCSI-U160 (part of SCSI-3) all commands and data are error checked by a cyclic redundancy check. SCSI-1 and SCSI-2 have the option of parity bit error checking. The Symbios Logic 53C810 chip is an example of a PCI host interface that can act as a SCSI target. The SCSI protocol defines communication from host to host, host to a peripheral device, and peripheral device to a peripheral device. There can be multiple hosts and multiple peripheral devices but there should be at least one host. ![]() Depending on the version, up to 8 or 16 devices can be attached to a single bus. Every device attaches to the SCSI bus in a similar manner. SCSI is a peer-to-peer peripheral interface. A SCSI device attaches to the bus but does not interrupt it. SPI is a parallel bus there is one set of electrical connections stretching from one end of the SCSI bus to the other. Parallel SCSI (formally, SCSI Parallel Interface, or SPI) is the earliest of the interface implementations in the SCSI family. ![]()

![]() ![]() Photo 3: 78-inch Prince P-Tip Prop on Dragonfly Whether he uses science, art, or magic, he can really create a great propeller. Lisa: Another thing that we did to significantly reduce noise and improve thrust was to use propellers custom-designed for our Dragonflys by Lonnie Prince of Prince Aircraft Company. For more information about that, you can check out Mike Stratman's article called 'The Stealth Rotax,' which is reprinted in his company's catalog. ![]() Tracy: Not only will that after-muffler silencer configuration work well on tugs powered both by the Rotax four-stroke engines and their two-stroke engines, but a Rotax intake silencer (p/n 825762) can also be added to their two-stoke engines for more noise reduction. As you can see in Photo 2, we made the exhaust exit point up to the sky, which significantly reduces noise propagation to people on the ground. Although designed for their two-stroke engines, we have found it to work very well with both of our four-stoke engines, as well. Lisa: One thing that we did to both engines to help make them quieter was to add an after-muffler silencer, available from Rotax, part number 978650. LiteFlite is now producing the Model C Dragonfly, which has gained certification overseas. Our 914-powered Dragonfly is a Model A with a reinforced Model B fuselage boom tube, while our 912-powered Dragonfly is a Model B, which came with a reinforced boom tube. We usually use the 912 tug for solo hang glider tows, and the 914 TurboTug for tandem hang glider and sailplane tows (see Photo 1). One of our tugs uses the 80-horsepower Rotax 912 four-stoke engine, and the other uses the Rotax 914 Turbo, both hung on Russell's engine mounts. Russell has made and supplied most, if not all, of the Rotax four-stoke engine mounts for Dragonflys in the U.S. We were very impressed when we flew behind it back then, and we were convinced that it was the best way to go for us. As far as we know, his original 1996 Dragonfly Model A TurboTug was the first Dragonfly to use a Rotax four-stroke engine. Credit must be given to Russell Brown of Quest Air for that development. Tracy: Use of the four-stroke Rotax engine on the Dragonfly was not our idea. Less noise generation was something that we did not expect, but found to be a great benefit of the four-stroke engines. Although their four-stoke engines cost more and weigh more, we felt that having more power and reliability would be safer, especially for tandem instruction tows, and that the greater up-front cost would actually be an investment that would be offset in the long term by faster tow turnaround times, greater fuel economy, and fewer rebuilds over time. However, the Rotax two-stroke engines do not provide the higher power output, fuel economy, long-term reliability, and time-between-overhaul (TBO) qualities that are inherent in the Rotax four-stoke engines. The stock Dragonfly configuration typically uses a 65-horsepower Rotax 582 two-stroke engine, which provides good performance at minimal cost and weight. Lisa: First, credit must be given to Bobby Bailey and Bill Moyes of LiteFlite in Australia for the design and manufacture of the Dragonfly. Question of the Month: When I came to fly with your club at Cloud 9 Field, I was very impressed with the climb performance of your tugs and how quiet they are. In this month's column, we will discuss some configuration and modification aspects of our Dragonfly tugs, in response to a question that we received from a visiting pilot at our field. ![]() ![]() ![]() The group, now all grown up, has naturally not been in touch with one another for a long time, some being influential in their own right at the current moment (one of them is a mayoral candidate). Then, perhaps, a new generation of heroic inventors will emerge.Rosie Perez ("In Living Color," "The Flight Attendant") plays Flora, a detective hell-bent on solving the mysterious case of the dead teen 20 years ago, while her partner Sullivan (Željko Ivanek), attempts to stop her from pushing too hard and landing herself in trouble with powerful people. Biology is therefore ripe to yield a clutch of new patent classes-possibly for things (neurological computers? furniture grown from seed?) as unimaginable to present-day folk as the telephone would have been to a soldier at the battle of Waterloo. Today’s understanding of biology, though, is roughly where that of the physical sciences was in the 19th century. Most inventions up until now have been based on physics or chemistry. What remains to be seen is whether biotechnology will change things. But that it has actually happened had not, previously, been demonstrated. This combinatorial explosion no doubt partly reflects the fact that the number of possible combinations grows faster than the number of codes they are based on. That suggests invention now proceeds mainly by recombining existing technologies and chimes with the idea that inventions were, in some sense, more fundamental in the past than they are today. The introduction of new combinations of codes has, however, continued to expand in step with the number of patents awarded. ![]() After that, the growth rate of new codes fell off dramatically, and that of new patents slightly. The number of codes and the number of patents both grew exponentially, at the same rate, until the 1870s (about the time of Edison’s light bulb see chart). These days, by contrast, nine-tenths are for inventions that combine at least two codes. When Dr Youn and her colleagues examined the patent office’s files they found that nearly half the patents issued by the United States during the 19th century were for single-code inventions. Only when a patent proposal arrives that cannot be slotted into the existing classification is a new one created. Overall, those records cover 474 classes and more than 160,000 codes. The office has records of these codes going back to 1790. A class-subclass pair-say, 136/206 for class 136 (batteries: thermoelectric and photoelectric) and subclass 206 (solar energy type)-is a unique code, and every patent is identified by at least one such code. ![]() Subclasses delineate processes, structural features and functional features of the technology in that particular class. A class distinguishes one technology from another. To do so, they classify the various technologies responsible for an invention’s novelty using an elaborate arrangement of codes.Įach subject grouping in USPTO’s scheme includes a major component called a class and a minor one called a subclass. The authorities there sort patent documents into groups based on common subject matter. She drew her data from the United States Patent and Trademark Office (USPTO)-not a perfect indicator of inventiveness, but probably a fair proxy for it. And together they exemplify the two sorts of novelty that exist, in differing proportions, in any successful invention: discovery and recombination.ĭr Youn has looked at the balance between these things, and how it may have changed. ![]() Both devices changed the world, though (Shockley’s was the foundation on which IT was built). In contrast, William Shockley’s transistor, invented 70 years later, involved a lot of new physics that Shockley and his colleagues had to work out for themselves. None of these things was novel in the 1870s, but in Edison’s hands the combination became a patentable invention. Thomas Edison’s light bulb, for example, was not so much the product of a metaphorical light-bulb moment of discovery as of the bringing together of pre-existing components-an electricity supply, a heated filament, a vacuum and a glass envelope. And, in a paper just published in the Journal of the Royal Society Interface, Youn Hyejin of Oxford University and her colleagues have provided some. To have an impression that something has changed is not, however, to prove that it really has. ![]() ![]()

They are in the top rank of all Meteorite classification schemes, usually called "Type". Stony-iron meteorites contain approximately even amounts of silicates and nickel-iron alloy, and are divided into two distinct groups: Pallasites and mesosiderites. The meteoric iron occurs in clasts instead of a matrix. Stony-iron meteorites contain approximately even amounts of silicates and nickel-iron alloy, and are divided into two distinct groups: Pallasites and. Mesosiderites are breccias which show signs of metamorphism. Pallasites have a matrix of meteoric iron with embedded silicates (most of it olivine). The stony-irons are divided into mesosiderites and pallasites. Stony-iron meteorites are all differentiated, meaning that they show signs of alteration. This distinguishes them from the stony meteorites, that are mostly silicates, and the iron meteorites, that are mostly meteoric iron. Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates.

![]() Pretty much every shower head has the same connection in the United States, 1/2″ NPT. The exceptions to this rule are showerheads sold in other countries, unconventional showerhead designs, or very old homes. As a result, any locally sold showerhead should be compatible with your shower arm. Showerheads have a universal thread size in the United States and Canada, which is designated as ½-inch NPT. Step 3: Include Access Panels in Design.Step 2: Determine Required Setback Measurements.Step 1: Design Around Floor Joist Locations.How do you reroute plumbing for a shower? Relocating a shower stall involves a major remodel of the bathroom, and it isn’t a weekend project in fact, simply removing the stall from its old location could easily take the whole weekend. ![]() In this case, it would be 40″ between the two. To make things easier, you can always go exactly halfway between the floor and the showerhead. If the showerhead is at 80″ then a good height is about 45″ above the ground. How far can shower head be from valve?īut for other showers, you can measure the distance from your shower head to the valve. You also need to consider additional costs, such as permits and labor. ![]() Sometimes, homeowners can expect to pay anywhere from $2,500-$3,500 to move a fixture. How much does it cost to relocate a shower? And if you mount the shower head more towards a window or the wall, you would barely be underneath the water, making it a very unsatisfactory shower. If your shower head isn’t centered, the water could drench your entire bathroom floor space. Connect the new shower head to the end of the shower arm clockwise, then connect the end of the shower hose to the mount. There are handheld shower heads that can replace tub spouts and others that can replace an existing shower head. To insert the showerhead onto the new shower arm, turn to the right (clockwise). (Be sure to protect the chrome with the soft cloth.) Turn counterclockwise. Move the showerhead to the new arm: Use the wrench to twist the shower head off the old arm. How do I change the location of my shower head? Then a single line can be installed from the shower control to the shower head. The shower control can be mounted wherever you would like it in that wall. MOEN MAGNETIX SHOWER HEAD ENGAGE HOW TO

Rock Band 2 is a 2008 music video game developed by Harmonix and distributed by MTV Games and Electronic Arts. The game, a sequel to Rock Band, has been released for the Xbox 360, PlayStation 3, Wii and PlayStation 2. Rock Band allows one to four players to simulate the playing of rock music by providing the players with peripherals modeled after musical instruments (a guitar peripheral for lead guitar and bass gameplay, a drum peripheral, and a microphone). The gameplay in Rock Band 2 is nearly identical to the original Rock Band, while also comparable to that in Guitar Hero. ![]() ![]() The game disc features 84 songs, all of which are master recordings. In addition, the game supports existing downloadable content from Rock Band, as well as tracks which have been exported from other Rock Band game discs. The game lets you modify and create your own songs with the help of an in-built song editor and provides with a EOF (Editor on Fire), dB (Feedback) and options. #Frets on fire song pack microphone freeTwenty additional tracks were released exclusively for Rock Band 2 as free downloadable content after the game was released. #Frets on fire song pack microphone codeA redeemable code that allows the player access to these songs is included with new copies of the game, except for the Wii version, where no code is required. With Rock Band 3, Xbox 360, PlayStation 3, and Wii players could export 70 of 84 songs by purchasing an Export Key for US$9.99. The 9 songs from bands fronted by Harmonix staff members are not offered in the initial export package however, these songs are offered at no cost in the " Rock Band Free 01" pack for the PlayStation 3 and Xbox 360, released on January 4, 2011. #Frets on fire song pack microphone manualThe export for the Xbox 360 and PlayStation 3 versions requires the code located on the back of the Rock Band 2 instruction manual this is the same code used for the redemption of the aforementioned bonus content. The process for export differs slightly on both platforms: Xbox 360 users only need to redeem the manual code directly within Rock Band 3 while PlayStation 3 users must redeem the manual code on the Rock Band website and then use the code given from the website within Rock Band 3.
