which was submitted in February 1978 and issued in December 1978. The power provide from the patent has some significant variations in the Apple II ability source constructed by Astec. A great deal from the control logic is on the primary facet during the patent and the secondary facet in the actual energy source.

In March 2007, Apple opposed a trademark software by startup Sector Labs, which sought to sign-up "Video Pod" like a mark determining goods associated with a video clip projector products. Apple argued which the proposed mark was simply "descriptive" and should be denied since the registration would result in a probability of confusion with Apple's pre-present "iPod" marks.

Just a little-recognised fact concerning the Apple II electric power supply is it had been at first assembled by Center-class California housewives as piecework.

This standard 150W XT ability supply makes use of the favored fifty percent-bridge design and style. The AC input filtering is on the appropriate. To your still left of This can be the Manage/driver circuit: the TL494 IC at the best controls the compact yellow drive transformer down below, which drives the two switching transistors to the heatsinks underneath.

I recognize that the transitors together with other componets are lesser, but that cannot be The entire matter. How are the more heavier factors been ready to shrink similar to the transformer and capacitors? I'm no professional but I are already pondering relating to this fore very quite a while. Thanks.

The SAMS photofact documentation with the IBM 5150 provides an in depth schematic of the power offer.

Hewlett Packard "specifies that A serious impact currently will be the All set availability of high pace, superior latest, low cost transistors accelerated by The present pattern towards switching style regulators. The business can make extensive utilization of switching in a full number of large energy models."

The 5V output is compared from a Zener diode and Handle comments and isolated through a transformer with two Principal windings and 1 secondary. It uses the flyback diode clamp winding.

Tandy 6000 (Astec AA11082). This 140W flyback power offer takes advantage of the diode clamp winding. The circuit is usually a rather sophisticated discrete circuit, because it utilizes a lift circuit explained in Astec patent 4326244, also by Elliot Josephson. It makes use of a 2SC1325A switching transistor.

In contrast to the primary technology apple iphone, the apple iphone 3G has to be activated in the store in most nations.[331] This makes the apple iphone 3G harder, although not unachievable, to hack. The need for in-shop her latest blog activation, in addition to the enormous variety of very first-technology iPhone and iPod Contact consumers upgrading to apple iphone OS 2.

Rod Holt deserves credit score for acquiring a switcher made in to the Apple][. But the accomplishment of the Apple][ provide lies squarely around the shoulders of Elliot Josephson. You mentioned that Elliot designed a power offer for Tandy, but Apple supplies involve his patent numbers. The supply Rod Holt made observed really restricted creation, it had been challenging to manufacture (at the very least from the standpoint of serious significant volume manufacturing exactly where tweaking and rework are an anathema).

[316][317][318] Tim Prepare dinner responded on the company's Site, outlining a need for encryption, arguing that should they develop a backdoor for one gadget, it would inevitably be utilized to compromise the privateness of other apple iphone end users.[319] On February 19, Apple communicated to journalists the password for the Apple ID to the apple iphone were improved inside of a day of The federal government getting it, preventing Apple from producing a workaround that may only target more mature gadgets.[320] See FBI–Apple encryption dispute.

It truly is excellent to check out an Engineer get some credit for his or her get the job done. Perhaps an influence source isn't that huge of a deal while in the broad scale. But in Steve Employment' entire world, just about every depth mattered. In per day when computer systems were being known to be noisy, it had been good to only listen to the on/off change.

A completely new demo is scheduled for March 2014, where Apple will request to stop Samsung from providing many of its existing units from the U.S. The case will contain further debate more than financial payment.[235] From the 2014 lawsuit, Samsung is accused of infringing five of Apple Inc.'s patents in 10 phone and tablet models, although Samsung has responded that has a counterclaim, by which it states that two patents for 9 phones and tablets have been infringed on by Apple.
