Omega Watches Value and Benefits

Omega watches are known for retaining their value for a long time. A big part of this is due to co-axial escapement. Assisted by the success of caliber 2500, Omega developed the first mass-production time-piece that incorporated a coaxial escapement. Invented by George Daniels, a watchmaker from England, and recognized as the most important watch-making advance in recent times. The coaxial escapement virtually eliminates the need for lubrication, which greatly increases precision and the need for maintenance over time.

Radial friction causes less strain on the movement's parts, as opposed to sliding friction. This in turn results in Omega's watches being able retain their value for a longer time than their competitors. It also reduces the amount of maintenance the time piece will need to undergo over time to virtually a fraction of watches with other types of movement.

Another factor in Omega watches retaining their value is the quality which they are produced with. Each new Omega movement has to pass extensive standards. The movements are tested in existing Omega watches, and, at the same time, various lab examinations are conducted to verify the movement's ability to resist temperature, shock and vibration. The precision of the movement is also tested. Along with this, when a new case has been produced, it is subjected to various tests as well. The decision on whether to manufacture a new case is only taken if the new prototype passes all tests assuring great quality.

Omega watches are heavily sought after time pieces due to the company's thorough advertising campaigns, and endorsement of major worl wide athletic competitions, such as the Olympics. By participating in massive marketing campaigns that drive sales, the Omega brand is has a universal perception of quality, precision and design.

The benefits of investing in Omega watches are plentiful. For one, after the severe financial crisis of 1975 to 1980, their debt was bought by banks in 1981. Switzerland's other watch-making giant Allgemeine Schweizerische Uhrenindustrie AG (ASUAG) was similarly saved a year later.

In 1983 the Holding ASUAG-SSIH was established, after significant downsizing, as well as the reformation of R&D. The new company achieved quick success and substantial growth. It is now considered one of the largest watch companies in the world. In 1998 the company changed its name to Swatch Group. It now owns Blancpain and Breguet. Although the company diversified over the years, its leading brand is still considered to be OMEGA.

Timing a circuit properly?

We are making a spinning marquee for a EE lab this semester. Basically a counter access memory addresses in an EEPROM and displays the code with LEDS, releasing each binary code in order to display the message. The problem is, I need to disable the counter when its displayed all the light combination, and then restart the sequence at the same radial point. Since i have 16 points of data, Ive run wire from the carry pin to the enable pin (logic low) of the 4 bit counter to disable it. I just don't know how to re-enable the counter at the same point. I'm using a 555 timer and a 74169 counter. Any ideas?

You want to synchronise the EPROM addresses with the position of the table, relying on persistance of vision to create a display. The whole circuitry has to sit on the rotating table. I would use a soldered circuit on matrix board once it is working, not one of those push in wire things. The wires are likely to fly out, just as you are showing everyone how well it works, and there is a balance problem with heavier objects.

Imagine you could use a push-button to re-enable the counter. Just have a simple Set / Reset latch using crossed over nand or nor gates. Figure out which pair gives the input logic you want (active high or low). Both states are available at the output. The carry output resets this latch, and the output of the latch stops the counter, as you do now. When you say stop I think you mean reset or clear, so all the addresses start again at zero. Press the button and it starts again.

Now to detect the radial position of the turntable...
This position pulse is used instead of the push-button. It is not reasonable to use the motor AC supply for synchronising, as an induction motor is not synchronised with the AC supply. It runs slower.

Use a hall effect device and magnet, for preference, because it is straight forward. Buy one with a momentary logic output, not latched. Using it, just make sure the magnet is close, like 1 or 2 mm, and they are all the right way around. Easy to test the operation. You do need a well made turntable.

An optical interrupter with LED and photo-diode or photo transistor. You need an amplifier with the photo-diode, which can have a speed issue if not designed properly. Don't use a Cadmium Disulphide photo-detector, too slow.

A coil of wire and a magnet will also work. This will provide a bipolar pulse, and could be a lot of volts with no load. Again it would need some signal processing, say pass it through a voltage limiting circuit to keep the pulse in the logic range, and a logic gate with a schmidt trigger input. It might only need a 47k series resistor from the coil into a CMOS gate which is diode clamped to the rails. Load the coil with a resistor to keep the pulse within reasonable bounds. Check with an oscilloscope. Not easy when it is rotating. You have to make a mockup.

You can restart the clock pulse as well as the counter. The 555 is simply reset along with the counter. Don't gate it, no benefit. That would give better synchronisation (less jitter sideways). It may not be necessary, but it is only one wire.

You may want to make a delay before the counter/clock restarts, this adjusts the radial position.

Another latch is a D type flip flop (in the dual package). You could just use it as a Set Reset latch.

The 555 timer should be adjustable in clock speed, to adjust the display width.

New approach to trapping sunlight with silicon nanowires
Washington, Mar 5 : Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) are developing a new approach, which would use silicon nanowires to better trap sunlight for future renewable green energy equations.
