    I got the package way earlier than I expected which was great! It came with 11 masks (one was a free sample) and there were two of each of the 5 kinds. Theyre comfortable to wear and make my skin feel extremely refreshed/soft. I also got TONS of small sample packages of other products which was an unexpected surprise~!

    Even if you arent nursing, it is a huge help to have this pillow. When my baby was little, this made a huge difference. I was exhausted from lack of sleep and from recovering from labor; I really appreciated being able to rest most of my babys weight on this pillow.

    This planner is super cute and useful. I would suggest looking for it on ebay for a lower price though. I really love that all the pages have layouts, but its up to you to fill them out. There are also many extra pages for taking notes and stuff. I decided to use the last colored pages as an address book. I think someone mentioned that the binding is kind of loose which worried them; however I think this was done on purpose so that the book can be opened all the way and you can use all the space on the pages.

    Love this fun printed swaddle for my baby boy. These are very comparable to aden and anais classic swaddles. Theyre huge and perfect for achieving a nice snuggly swaddle and incredibly versatile. Its modern and great quality, however I do need to mention that the color of the cats are more pink than red, which I didnt know until I opened the package. My son frequently gets mistaken for a girl when hes wrapped in this but theres no reason boys cant rock a little pink! Love to use this as a stroller cover in the sun, burp cloth, blanket, swaddle etc. I definitely plan on ordering more prints

    I have used the Avon Sun+Sport Refresh Sunscreen Lotion for two years now and I love the feel and the way I look with it on. You use it for the sun but it is recommended for wrinkles as well. There was a advertisement on TV about it was the best cream for wrinkles and then my Avon Representative say they are going to discontinue it and so I went on the hunt for some and ordered three containers.

    Sleek blush is the bomb!!!! I applied once and it lasted all night. I work third shift. It was also noticed by the guys i work with. They thought I was blushing all night. Goes on easy with a stippling brush. It looks very bright and loud, but goes on a healthy looking flush color. I am a woman of color and I will be buying more of this blush. Reasonably price item. You will not be disappointed.

    We love this car seat!!!! It is by far the best car seat we have ever purchased. Installation was a breeze and even before securing it with the anchoring system, this car seat was already very secure with just the seat belt clamps. It is literally unmovable. I love it that I wont have to disassemble it to move the straps. Weve purchased several car seats over the years and were reluctant to spend this much on a seat. However, this is the best car seat we have ever owned and well worth the expense.

    I finally found a moisturizer that is heaven sent! I live in super dry Arizona and my skin was flaking with dryness until I started using this deep hydrating moisturizer. When you apply it, it instantly absorbs into your skin with no residue. It almost feels like your skin is drinking it up. It is hard to explain. I really wish this stuff came in huge pump bottles so I could slather on my body as well.

    I use these bands to pull my hair up while I am sleeping. They dont leave an indentation and they are the perfect size. I only have to make 2 twists for it to fit properly without being too tight for sleeping. They only came in this color so was a little disappointed but for my use, they are perfect.

Belden 1694A SDI Cable

The industry standard in serial digital performance

Since Blue Jeans Cable"s earliest days, we"ve been working with Belden 1694A SDI coaxial cable -- a high-bandwidth, low-loss SDI cable used by industry professionals for decades. 1694A is good for anything from standard-definition SDI all the way up through 6G, and will support runs in the hundreds of feet (see chart below).

The BNC: Canare BCP-B53

For connectors, we use the Canare BCP-B53 male BNC plug. This BNC is a three-piece crimp design with excellent mechanical stability and electrical characteristics, and features a broad grip surface for ease of use. It was designed specifically to fit Belden 1694A, and so its dimensions are ideal for a smooth cable-to-plug transition.

Product highlights:

  • 18 AWG bare ETP copper center conductor
  • Foamed HDPE dielectric
  • Belden Duofoil two-sided foil shield, overlain with 95% coverage tinned copper braid
  • Rated CMR; allows installation in walls and risers
  • Available in ten jacket colors
  • Bulk cable made in Richmond, Indiana; finished assembly made in our shop in Seattle, WA
  • Canare BNCs for excellent mechanical and electrical performance

SDI Cable: More Complex Than It Looks

Coaxial cable seems simple, doesn"t it? And yet, when high bandwidth is to be delivered, it"s anything but simple to actually manufacture a consistent, precision quality cable. Why is that?

Any transmission line has a characteristic impedance, and in the case of video cable, equipment invariably calls for that to be 75 ohms. The characteristic impedance of a cable is a function of its physical geometry and materials: especially the dielectric, that inconsequential-looking layer of plastic which insulates the center conductor from the shield. Characteristic impedance isn"t load impedance: you can take your ohmmeter to video cable and measure all you like, but you won"t find 75 ohms anywhere. Rather, the characteristic impedance of a line is a way of describing how its impedance affects the impedance of the load: the load should look like a 75 ohm load (not just in terms of resistance, but in terms of reactance) when it"s hooked up directly to the source, and it should look like a 75 ohm load if it"s hooked up through a run of cable, no matter the length. A balance of inductive and capacitive reactance – from the inductance and capacitance of the cable – achieve this end.

But, alas, it"s not so simple as looking at the massed values of inductance and capacitance for the cable run. Signals propagate down a cable over time – traveling at a significant fraction of the speed of light – and react to local conditions at every point along the way. Changes in the impedance as seen at any point along the line cause signal reflections – what we call "return loss" – and these add up, not only diminishing but actually interfering with the intended signal. Above all, what a cable needs, to minimize these reflections, is consistency: consistency of dimensions, even down to microscopic levels, and consistency of materials. If the density of bubbles in the dielectric varies, or a wire has been drawn over a wheel that"s out of round and so gets slightly bigger and smaller along the way, or any of a number of other little manufacturing issues, return loss rears its ugly head.

Belden, with its engineering center in Richmond, Indiana, knew these issues when SDI came onto the scene: it had been producing precision coaxial cables for other applications such as early digital telecommunications networks. And so while a precision video cable like 1694A might look superficially a lot like, say, a ten-cents-a-foot CATV drop cable, the engineering and the manufacturing resources that go into it are a world apart. Equipment is carefully maintained to eliminate small periodicities and inconsistencies in dimensions. Dielectric extrusion is continuously monitored during production to catch even small departures from tight tolerances. Everything from tension on braider wires to the consistency of foil overlaps to the amount of nitrogen going into the polyethylene foam is watched, and checked, and the final product is sweep-tested just in case something, somewhere, has been missed. The result is a cable of tremendous physical and electrical consistency.

And we at Blue Jeans Cable should know. We"ve handled millions of feet of the stuff.

The Stripper

Stripping cable is a critical step: dimensions that are out of whack will cause damage to the shield braid or result in a weakened mechanical connection. All of our coaxes are stripped on Schleuniger Swiss-made coaxial cable strippers, custom-programmed for the precise dimensional requirements of the cable and the connector.

The Resulting Strip

The resulting strip is clean and dimensionally consistent, for a perfect fit every time. The fast-spinning blades have cut the braid without fraying or disrupting it and the center conductor is just the right length for full engagement with the pin.

The Crimper

Instead of hand crimping we use these three-ton pneumatic presses; the straight vertical action of the press gives the crimp perfect symmetry, and the heavy force means no crimp is ever halfway-done.

The Finished Cable

All of these details -- conductor and shield and dielectric lengths just right, powerful crimping force using the specified dies, and careful handling and inspection by our experienced technicians -- mean that we can produce to the highest standards of assembly quality, day in and day out.

Blue Jeans Cable: Decades of Experience in Precision Cable Assembly

Blue Jeans Cable has been in the cable assembly business since 2002, with our primary manufacturing operation in Seattle, Washington. Today we occupy a small industrial building in the Interbay neighborhood where we employ about a dozen people in cable assembly. From the very beginning, we"ve emphasized assembly, not import: if we can build the cable here, rather than offshoring it, we do, and in addition to conventional assembly techniques we"ve introduced novel materials, methods and processes, like our ultrasonically-welded speaker cable. We can"t underprice our foreign competition, but what we can do is produce goods of consistent higher quality; to do that we use the best American-made cable and the highest assembly quality standards. To do that, you need experienced workers, and so we try to be the sort of place where people want to work; our employee retention is high and that means that, likelier than not, the technician assembling your cable is someone who"s been doing this work for at least ten years. American manufacturing isn"t dead, and neither are good American manufacturing jobs; and we thank our customers for making this possible.
