Energous WattUp mid-range power transmitter granted approval by FCC
mikethemartian said:I would think one of the main issues with a product like this is that it would just waste quite a bit of energy. It seems like it sends the EM radiation in a omnidirectional manner as a typical light bulb does. Only the EM flux that passes through the cross section of the collector (which I assume is a coil) provides useful power. The rest will just scatter and be absorbed by the surroundings.
Their product page (http://http//www.energous.com/technology/receivers/) says this:
"WattUp® uses pocket-forming technology to accurately direct energy to the receiver. The technology dynamically adjusts the shape and content of the RF waves so they can be directed to a specific location in 3D space. (my emphasis) There, the energy is gathered by the receiver’s special antennas where WattUp® ASICs convert the RF signal to DC current, delivering a charge to the battery."
To me, this implies some sort of steerable (transmit) antenna, although "pocket-forming" means nothing to me. Their software technology page touts a highly configurable system of charging multiple devices at different power levels (and 3D locations), so there must be some micro-location method (beacons?) to tell the transmitter the device's exact 3D location. Of course, I could be reading too much into this.
I couldn't find what happens if you move the device during charging. Will it stop charging? Will the system redirect the charging signal dynamically as the device is moved?

First FDA-certified Apple Watch accessory is AliveCor's Kardia Band EKG meter
foggyhill said:rogifan_new said:techno said:This is where the watch takes a very important path. With more FDA approved devices like this, the value of the Apple Watch significantly improves for the non-fanboys.Medical devices are very expensive and you'd be surprised how much any one who actually needs it will pay for them.Devices that otherwise should cost $100 bucks cost $1000 if they are "FDA approved", so $200 is no biggie.This is an area ripe for disruption. Apple taking care of the data management / display / storage means those medical device makers could concentrate on something they're actually good at (the medical aspect) and not everything else, which they are undoubtedly they are not.

Walmart Pay uses bizarre metric to claim its dominance over Apple Pay is approaching
I thought CurrentC used a direct connection to your bank account (to avoid credit card fees).
Is WalmartPay the same way?
I just checked here. Yes, Walmart know about you and your bank account. Seems like WalmartPay is just CurrentC warmed over.
Thankfully, Apple take financial security and privacy seriously.

First look: Apple's bionic iPhone X with Face ID
bb-15 said:StrangeDays said:mr. h said:larryjw said:I attach zero importance to the 5W charger. That might be an issue for first time Apple buyers, but everyone else has a drawer filled with Apple chargers. Apple put a minimal charger in because they know anything more is unnecessary.
The point is, the iPhone X can be charged at a much faster rate than the included 5 W adaptor is capable of. For very little incremental cost (to Apple), Apple could include a more powerful charger. Given the high retail price of the iPhone X, I agree that it just seems mean-spirited of Apple to not include a more powerful adaptor.

1. Apple including the 5W charger with the iPhone X was considered a flaw in the First Look article.
- While some claim an extreme pro Apple bias in the article; this criticism of Apple in the article shows no evidence of that.
- I agree that selling the 5W charger with the iPhone X was an oversight on Apple's part.
2. Should a person pay for and use the 29-watt Apple charger for the iPhone X? I wouldn't.
Tests (from AppleInsider & BGR) have shown that the very common 12W iPad charger is very close to the 29W charger in terms of speed. (The 12W iPad charger is also much cheaper.)http://bgr.com/2017/10/10/iphone-8-charging-speeds-fast-charging-iphone-x/
I've got extra 12W iPad chargers. Those are the ones I would use when I eventually get an iPhone X (or XI) later next year.
And now you say (or someone says) that the 12 watter's charging time is close to the 29 watter, so we can reasonably estimate that Apple limit the max charging current to a bit over 2 amps. I picked the Griffin so I can carry one charger for both iPhone and iPad when traveling internationally, and it works great.
Apple (as well as others) limit the max charging current to protect the battery from heat buildup (bad things happen with heat, such as swelling batteries or explosion), so even if you have a 100W charger, your phone won't be able to take advantage of the higher available power.
Edit: removed reference to Amazon pricing.

Apple designing iPhones, iPads without Qualcomm modems after key testing software withheld...
1STnTENDERBITS said:gregg thurman said:GG1 said:k2kw said:Soli said:I don't see how this ends well for Qualcomm.
When that day happens, Intel and others can effectively ignore CDMA2000 support in baseband chips (and the majority of Qualcomm IP issues). Or maybe it takes someone like Apple to move that date up with Apple-designed UMTS/LTE-only baseband chips in future iPhones. Add in Samsung's Exynos baseband chips (which I don't believe support CDMA2000), and together their smartphone volume may push the carriers to LTE faster.
As Soli pointed out, the Apple Watch only works on UMTS/LTE (both GSM-based), but Verizon and Sprint already have (some) LTE support, so the AW works there. Maybe Apple are already pushing for LTE-only adoption starting with the AW?
On a different note, Qualcomm must know that the sunset for CDMA2000 is near, so why continue to be so arrogant with licensing? Qualcomm should be loosening licensing fees to get more customers onboard with their Snapdragon chipsets for 5G and beyond. After CDMA2000 sunsets, Qualcomm will be competing with Intel/Samsung/Mediatek/others more directly.
