Electronic equipment needs an efficient means of managing and dispersing heat as systems continue to shrink in size. All these examples require heat to be transferred or dispersed effectively, using a minimum amount of space. Pyrolytic Highly Oriented Graphite Sheet is made of graphite with a structure that is close to a single crystal. PGS film is used to transfer heat away from a heat source, or to diffuse or spread heat away from a hot spot (A>B) as shown in figure 4. Figure 7 demonstrates how heat can be transferred away from an IC (LED) to the casing in a camera design, reducing the heat sinking that is required. Figure 8 shows how when applied in a IGBT or switching FET module, PGS acts as a thermal interface, reducing the thermal contact resistance and thermal soaking required. PGS has a lower thermal resistance than silicon sheet material and graphite products from other manufacturers. In my last post, I have walked you through on how to write firmware for the MSP430 using Visual Studio and VisualGDB.  This post however is now focused on developing for the CC3200 using Visual Studio.
There is one big hurdle with this approach, and that is debugging.  Setting up the environment to debug the firmware was a bit tricky such that it requires changes to OpenOCD, one needs to configure the connection interface with LaunchpadXL, etc.
Now that the development environment has been setup for my sensor nodes, my next posts will be more design-focused and will go through the guts of the CFMS (Carbon Footprint Monitoring System). Although the amplifier is capable of a rail-to-rail signal (3.3v in this case), we map it to a 1v peak-to-peak signal. I hope you didn’t throw the boxes away, because there is a pair of plastic tweezers embedded into the wall of each cardboard box, just in case you didn’t have a pair.
This image is my attempt at showing the relative size of each inductor package with respect to each other.
If you consider all the MAPI packages they cover the same inductance span as the SPC, but their package is significantly smaller. The first thing that I noticed was, for 47 uH, the MAPI inductor has over twice the DC resistance of the SPC inductors. Figure 3 shows the launch pad designators on the left (GND and LP_+5V) and my decoupled versions on the right (SGND and VCCS). I never used a MQTT so I'm getting some difficulties when I try to get notifications when new data is published to AirVantage.

As applications get thinner and lighter, this statement has never been more true, yet space and weight restrictions – especially in portable mobile devices – mean that conventional solutions may not be feasible.  But it’s not just consumer products such as smartphones, tablets and cameras that are at risk. Pyrolytic Graphite Sheet (PGS) is a new, ultra-light graphite interface film material, developed by Panasonic, which has a thermal conductivity up to five times greater than copper. The temperatures at the ABS (Acrylnitril-Butadien-Styrol )surface, the IC and the PCB are shown for two different 70µm thick PGS sheet sizes. Silicone grease has a lower thermal resistance, but it has the disadvantage of drying up over time and losing effectiveness. It's taking a long time because I'm trying to use TI parts for every component, and the plague (read flu) just passed through my household. This PCB is going to supply power to all your sensors and allow the sensor outputs to be digitized by one of your launch pads. And I'm sure data is being published because I can see new values on Monitor -> Systems page in AirVantage control panel.

The filter also provides a shield to RF energy, which would otherwise leak in or out of an enclosure. These chambers, sometimes called microwave dark rooms, are usually large rooms lined with absorbing materials to reduce R-F reflections. Most electronic equipment requires it to be as close to 0 V and not to exceed 1&Mac218;2 V. For example, in a circuit with one outgoing signal conductor and one ground conductor, the common-mode current is the component of the total signal current that flows in the same direction on both conductors. Snap-on current probes measure the normal-mode current in a wire pair, coax, or wire bundle. Gaskets are used to fill and electrically join and seal leaky apertures between these mating members in order to maintain a minimum shielding effectiveness over a defined frequency spectrum. It is placed between the primary and secondary windings of a transformer to reduce coupling capacitance and common-mode noise. In communications circuits, it suppresses unwanted frequencies, noise, or separates channels.
The electrical lengths and element spacings are chosen so the bi-directional radiation pattern, impedance, and other antenna properties are repeated for several frequencies. Exists when either the transmitter or receiver is carrier operated (has an antenna), causing undesired responses to or from other electronic equipment or systems.
The term typically refers to the residual line-frequency-related AC part in the output of a DC power supply that arises as a result of incomplete or inadequate filtering.
The measurement is the ratio of the signal received without the shield to the signal received inside the shield. It is made from a variety of materials including fabric-wrapped foam, wire mesh, stamped metal, and elastomer. Shielding materials are always metals, metalized plastics (conductive coatings) or conductive composites. Some provide high shielding, such as honeycomb, while others provide air filtering, as well.
A perfect match has a VSWR of 1.0 while an imperfect match has a greater standing wave ratio value. It is pliable enough to be cut and folded into complex three dimensional shapes then simply stuck onto the heat source to diffuse the heat or provide a path for heat to flow to a cold wall. It’s always seems to be current for an inductor, voltage for a capacitor, and power for a resistor. The first two digits refer to the square dimensions of the package (width and length) and the second two digits are the height. I'd go with the MAPI if possible because it is so much smaller and it's 75% the cost of the SPC inductor.
I need to drive a pump in my design, so I used TI's WEBENCH software (on their website) to design a 12 Volt to 3.3 Volt regulator using the TPS62175.
I am a Chemical Engineer who is working in IT Consulting and I've realized how much I miss working with hardware so I'm hoping that Arduino can be a good learning opportunity for me! If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
Air filters are often used where wave-guide-beyond-cut-off honeycomb shielding would otherwise be used.
The ratio expresses the capability of the device to reject the effect of a voltage that is applied simultaneously to both input terminals.
Tiles may be used with dielectric materials or as a hybrid combination with dielectric pyramids.
The cell also can be used as a detector to measure radiation emitted by devices inside the cell. Digital by nature has higher noise immunity, so it stands to reason that the circuitry is likely noisier than its analog counterpart. Learning how to fix earthing and shielding problems on the job can be very expensive and frustrating. In Fig 1, notice the first three types (left to right) have the term Power Inductor directly in their names. Personally, I lean more towards price than anything else, so that is what makes the MAPI more attractive to me. On TI's website if you are looking at the "main page" for a part on the right side will be a link to open the WEBENCH designer for that part. I don't want any of that noise created by the digital circuitry to show up in my analog circuits (sensors). Next we'll talk about an extremely important concept with regard to mixed-signal design, that is designs including both an analog and digital ground.
The easiest way for this noise to get to the analog parts is via the power supply or the ground connection.
It can handle the same or more current than the SPC package, and it's very low profile.The LHMI and SPC cost about the same, so if you need the space you might choose the LHMI. Given that, we separate them using inductors because our DC signal can pass unaltered and the AC signals (noise) will be presented with a high impedance. They have other applications, but by far the most common is likely the design of switching DC to DC voltage converters (think Buck or Boost regulators). The specifications of the LHMI claim "no acoustic noise and no leakage field", so maybe they are targeted at quiet power supplies for audio equipment? I've heard it mentioned to steer clear of switching regulators for audio applications, but that was back when the switching frequencies were in the tens of kilohertz. Depending upon your efficiency requirement the presence of a shield can be quite important. I think I will be using the MAPI inductors, because they offer the best performance for the price.
There are caveats here, especially with the ground decoupling, but unless you are dealing with high return currents it's a pretty safe practice. If the return current from the signal or analog ground is high enough the I?R loss of the inductor will lift the analog ground above digital ground. The WE-MAPI inductors are shielded as well and made from a metal alloy, likely proprietary and patented.
