This was not a problem that Public Security Section 9 would be well equipped to handle: When ghosting shows up in a production run of electronic displays destined to be mounted in Ghostbusters’ Proton Pack Shells, unlicensed particle accelerators designed solely to weaken and help capture ghosts, one has to wonder: Who you gonna call?”

Now, this is where the analyzer comes in. I had noticed that the insertion loss from input port to either output port was cutting off short like a low-pass filter. This told me that toroids were not wound with the right wire gauge, and that the auto-transformer toroid needed more twists per inch and a change in wire gauge to achieve a different characteristic impedance.

I went to my workbench and began winding some new toroids with No. 37 AWG THN wire with about 10 twists per inch. The number of turns for the auto-transformer and the output coil remained the same, and I kept the same value of capacitance that would balance (match) the input impedance to the two outputs of 50 ohms each. This meant that an impedance of 100 ohms was needed at the junction of the two taps and capacitor in order to have a balanced split.

When I was finished winding the toroids and mounting them, and the capacitor into another gold-plated flat pick, I took the device over to the test bench and ran the test parameters. Insertion loss was +/- 0.25 db flat across the entire frequency span.

At first, I couldn’t believe I hit it on the first try, so I made certain my frequency generator was set correctly, and that the RF analyzer was properly zeroed out to account for any loss introduced by the test setup and test fixture. Once I was certain my setup and measurements were correct and repeatable, I called the design engineer back over to the test bench and showed him how this design met the customer’s specifications.

The TM651 is available in a chip-scale package that can be overmolded inside the package of the chip for which it is supplying the timing signals, or in a traditional land-grid array can that is pin-compatible with quartz crystal oscillators.

By 2017, all of that year’s end-of-life refrigerators, TVs, mobile phones, computers, monitors, e-toys, and other products with a battery or electrical cord worldwide could fill a line of 40-ton trucks end to end on a highway straddling three quarters of the Equator.

The forecast, based on data compiled by the Solving the E-Waste Problem (StEP) Initiative, represents a global jump of 33% in just five years. While most of these used e-products are destined for disposal, gradually improving efforts in some regions are diverting some of it to recycling and reuse.

Now we’ll have 2-in-1s for consumers and 2-in-1s for business,” said Skaugen in his keynote:

In addition, we are integrating location-based services into the technology. If you are walking into a new building you can do things like ask where’s the closest printer, it can tell which conference rooms are occupied, so you can find an empty conference room, and it can even do document protection, so you can get access to confidential documents, but when you walk out of the building it can restrict access to those confidential documents.

Skaugen also promised that vPro will get a boost in 2014 from Intel’s 14-nanometer Broadwell microarchitecture, which will not only improve performance, but extend battery life for mobile devices using vPro.
