Okay, so if you thought the CATSeye matchbox-sized tracking device was a bit too big or cumbersome, the gang is back with something decidedly smaller and more discrete. Introducing the CATS.i, also known as CATSeye Mk2. It's got all the same functionality as its predecessor -- GPS, GSM/GPRS, RF, internet / SMS controls, etc. -- but is now only eight millimeters thick (or twelve if you chose the thinner "folded over" arrangement) and completely waterproof. Power options include a Li-ion battery, solar power, or any number of other ways you can think to run juice. Have an urge to keep track of all your family members and loved ones even more secretly than before? The new devices ship next month.

Think fast! You've just stumbled upon this week's episode of Ask Engadget, and just like those "Choose Your Own Adventure" books from yesteryear, you've a few choices here. One is to leave like a coward; another is to really dig in and contribute; and another is to drop some knowledge and send in a question of your own to ask at engadget dawt com. While you ponder which route is best for you, here's Matthew's plea:

"There are so many GPS trackers on the market today to choose from. I'm just looking for basic monitoring abilities and decent battery life, and of course I want one that's as small and discrete as possible. Which is the best one for less than $300?"

No need to confess in comments what you use your own tracker for (trust us, we could narrow it down on our own), but do tell if you've found a winner. Bonus points if your module has landed your scandalous SO on a recent episode of Cheaters.

Despite being oh-so-promising years ago, we've seen little innovation in the RFID space over the past several months. Today, however, CenTrak's proving that the dream is still somewhat alive. The outfit has just introduced the planet's thinnest hybrid active Radio Frequency Identification tag, which is said to be so thin that it's almost "indistinguishable from a standard employee badge." The IT-740 Staff Badge checks in at just three millimeters thick and includes a trio of programmable buttons, a system controlled LED, hole mounts for portrait or landscape orientation, water resistance for easy cleaning and "ultra long battery-life." For employees, rocking one of these guarantees that your superior will recognize every step you take, every move you make and every bond you break. Which, sadly enough, isn't nearly as bodacious as The Police make it sound. Bonus coverage after the break.

Those sadistic souls over at Lightning GPS are at it again, making the lives of parents and promiscuous children awesome and horrible, respectively. Just in case NavTrac's RTV10 PND isn't enough to keep your mind at ease when Johnny (and his track record of poor decision making) is out and about, there's the newly announced NavGenius. At first glance, this here navigator is about as vanilla as they come, but underneath the shell is a dedicated tracking module which enables the owner to monitor every turn, stop and donut from the web. Heck, you can even re-route vehicles from any connected computer, and the owner can get an SMS should the driver exceed a certain speed or break a customizable perimeter. All that's required to shatter the last pinch of trust you actually had with your offspring is $599.95 up front and $39.95 per month for the tracking service -- which you only pay until they wise up and take a Louisville Slugger to the device.

Can't say we've ever heard of NavTrac, but we are digging the differentiation seen in its RTV10 portable navigation device. Hosted up by LiveViewGPS, this unique navigator not only provides the usual turn-by-turn guidance to get you from point A to point Z, but it also includes a GPS tracking function (for fleet managers and suspicious parents) as well as two-way messaging functionality. While it's not truly a "connected GPS," this one does provide more communication with the outside world than most, and if you're curious of the specs, it features a 4.3-inch 480 x 272 touchscreen, built-in speaker, 4GB of internal flash memory, 64MB of DRAM, a SiRF Atlas III GPS module and a rechargeable Li-ion. Sadly, this no-namer won't run you cheap, as the unit itself rings up at $599 while the subscription to the aforementioned communication services will knock you back another $39.95 per month. Full release is after the break.

Not that sneaky, minuscule GPS trackers are impossible to come by, but with kids growing more and more mischievous, outraged parents are demanding more options. At least that's the word passed on by Lightning GPS' Jason Lazarus, who has just recently decided to make its ridiculously small Spark Nano available to the public. You see, this here company has generally thrived on providing covert GPS trackers to military and law enforcement, but now even civilians are being allowed in on the fun. The device, which is obviously used to track whatever or whomever you wish, is about the size of a 9-volt battery and can easily withstand bumps, bruises and the occasional drink spill. Users who implant one can track the subject via the web (shown after the break) or phone, and you can count on five solid days of continuous tracking when the rechargeable battery is topped off. It's shipping now from BrickHouse Security for $299.95.

We've seen birds tasked with carrying around sensors in order to provide data about external happenings, but up until now, tracking birds' migration patterns from start to finish has been a tedious, if not impossible task. Gurus from York University in Toronto have apparently figured out the solution, and it all sounds much simpler than you might imagine. By equipping birds with minuscule "backpacks" -- which weigh less than a dime and use geolocators to collect all sorts of information about flight times, patterns, stopovers and speed -- scientists can get an accurate look at where the animals were and when they were there. In a recent test involving 34 birds, researchers were able to retrieve the packs from 7, and while that may not be a majority, biologist J. M. Stutchbury noted that this "was 7 more than anybody else." Right you are, Doc.

Your options are pretty wide open when it comes to personal GPS trackers, but Xact Technology is hoping to catch your heart by promising no monthly fees for its XACT | TRAX. Hailed as an ideal solution for keeping tabs on pets, loved ones, movable property, etc., the GPS tracking module relies on a proprietary, web based portal in order to see where your subject is and to set "geo-fences." Location requests can be sent via the web or SMS, and readouts are provided on an easy-to-read map along with physical address, date and time. Sadly, we've no price to share, but at least you can rest assured that the cost of entry is it.

Little known Lok8u has traveled all the way from the UK to be in Vegas this week, but it's certainly not for the despicable reasons you think. In fact, the locations services company is setting up shop at CES in order to debut its Nu•M8 GPS child locator, a so-called "innovative new best friend for parents and children." The device is said to be the first of its kind created specifically to be worn by children with the technology "cleverly concealed within a child's digital watch." Granted, the styling is questionable for youngsters over 9 or 10, but by that age they ought to be toting their very own beeper, right? Of note, the watch will also send an alert if it's ever "forcibly removed," though it'll cost you £149.99 ($218) for the peace of mind come Spring.

We heard some pretty far-fetched stuff back in June to the tune of a break-apart DualShock 3, and lo and behold, it seems that someone at Sony Computer Entertainment America is taking the idea quite seriously. A recent patent application was filed by the company, and it fairly clearly lays out the very kind of design we'd (not really) been expecting. In essence, the gamepad would consist of two pieces, each of which would utilize an "ultrasonic tracking system" for some type of game console / peripheral to recognize 3D inputs. Best of all, the approach here sounds significantly different enough from what's used in the Wiimote that Sony could avoid months upon months of litigation -- imagine that, right? It's hard to say whether this stroke of genius will ever amount to anything, but at least there's a chance, however minuscule.

Just under a year ago, Russian Prime Minister Vladimir Putin announced his hopes that one day he could pinpoint the location of his black Labrador, Koni, at any time of the day. Today, a dream has been realized. Mr. Putin has finally procured a satellite collar that will enable him to track the lab regardless of which of the eleven times zones she may be in while waltzing through Russia. Once the collar was slipped on, Deputy Prime Minister Sergei Ivanov immediately said "she looks sad, her free life is over." Putin didn't miss a beat when snapping back: "In Soviet Russia, GLONASS track you!"

Hunker down and find that tin foil cap, pronto! Privacy advocates, we've a new target for you to bang on: Integrated Media Measurement. The 4,900-person media research company is looking to take advertising measurement to a whole new level (or new low, as it were) by embedding tracking modules within cellphones. In short, the module picks up audio from ads and records information about the exposure; in the future, if you were to purchase whatever product you heard about (like seeing a movie that was plugged), it would register a hit and deem you a sucker. As of now, the only testers with these freaky phones are individuals who signed up for this stuff, but you better believe major marketing firms (and TV / movie studios in particular) are perking their ears up and begging to know more.

It's not quite a Batman-type science-bending project, but DARPA's apparently hush hush "Gandalf" initiative looks to be fairly ambitious nonetheless -- at least as far as we can tell from the rather vague statements that have been made about it. In an announcement of sorts yesterday, DARPA reportedly said that the project's goal is to use "set of handheld devices" to track down a specific "signal emitter of interest" using radio frequency geolocation, and presumably some other measures they're not about to dish the details on. The Register's Lew Page further extrapolates that could mean that a group of undercover operatives or special-forces troops would be able to be dispersed near a target and hone in on a particular cellphone, or other electronic device for that matter, and then proceed to track it with no one the wiser. Whatever it is, it's going to be discussed at an event in Virginia later this month, though we're not exactly expecting any first-hand reports to come out of that.

Nintendo may not have been totally forthcoming with third-party devs about its MotionPlus add-on, but no secrets (okay, maybe a few) were withheld from AiLive. As it turns out, said outfit actually collaborated with Nintendo in order to create the MotionPlus hardware, and it's extra kindly offering up LiveMove 2 "to help game developers take full advantage of its capabilities." According to the company, LiveMove 2 can slash up to half a year off of the time required to tie basic functionality of the device into a game, though we're obviously in no position to confirm / deny. For the small minority that cares more about how MotionPlus works rather than just accepting the fact that it does, check out the read link for a few geektastic vids.

For better or worse, targeted advertising isn't going anywhere. Seemingly, it's not getting any more discrete, either. NEC's Digital Signage Solution combines a camera, a large display and a FeliCa contactless IC card reader / writer in order to dole out advertisements that cater to certain demographics. The system includes the innate ability to determine "gender, generation and other attributes" of a person in order to serve up advertisements that will cause him / her to spend some dough. From there, the individual can scan their phone in order to access related content on their mobile internet browser. That's all and fine and dandy we suppose, but how on Earth do you convince busy citizens to stop by and have a look at an otherwise uninteresting flat-panel?
