Digital Yacht - From Southampton Boat Show 2010 - Exclusive Look at iAIS Wireless Receiver

Digital Yacht has developed a new, low cost navigation device for use with Apple's popular range of mobile products. Called iAIS, it wirelessly links a boat's navigation data to the Apple iPhone, iPad or iTouch. It also incorporates a highly sophisticated, dual channel Automatic Identification System (AIS) receiver allowing compatible "apps" access to NMEA instrument, GPS and AIS data. iAIS, which helps boaters identify other vessels that are equipped with an AIS transponder, communicates with the Apple devices via a WiFi interface. iPad and iPhone users simply turn on their device to wirelessly connect to the iAIS hot spot. No connection to the internet is needed and there are no cumbersome cables to connect. The AIS data (which brings information such as position, name, call sign, MMSI number, course and speed of other ships) then becomes available for any compatible application. This information is essential in alerting boaters to others in close proximity and can help calculate if paths are likely to cross and how soon. AIS is an essential piece of kit that enthusiasts and professionals alike will not set sail without, as it is proving to be key in collision avoidance. iAIS also multiplexes any other NMEA data that is available on board the boat - for instance GPS, depth, speed, wind etc. All of this information is combined with the AIS data into the wireless feed. Some users have complained that the GPS devices incorporated into the iPhone and iPad suffer from jitter ...

Tilt TV Wall Mount Specifically Designed for the Sharp LC-65D64U

!±8± Tilt TV Wall Mount Specifically Designed for the Sharp LC-65D64U

Finally a TV wall mount has been engineered specifically with the Sharp 65" HDTV in mind. The VESA pattern for the Sharp LC-65D64U is 440mm W x 650mm H. The VESA spacing of the vertical arms distance is far greater than most mounts that are out on the market today. The designers took that vertical arm spacing into consideration as well as the fact that it requires M10 screws to attach them to the back of the TV. This tilting wall mount has a 28" wide wall plate that can mount to wood studs on 16" or 24" centers. Once mounted it can support up to 300 lbs. It can be mounted into concrete as well but, the minimum thickness required is 6". Concrete anchors for this can be purchased at you local hardware store.

The vertical arm can slide laterally on the wall plate for centering if needed. When the TV is set onto the wall mounting plate it can be positioned either flat or tilted downward up to 12 degrees simply by loosing a knob. When installing a large TV of this size it is always advisable to have two people to support the TV when attaching it to the wall plate. Once the TV has been placed onto the horizontal rails that support the vertical arm, secure it by tightening two locking screws located on the lower portion of the arms. This will prevent the TV from being accidentally lifted off the rails and falling onto the floor. When parked in the flat position the back of the TV will be 4.75 inches from the wall.

Electronic Safe Locks - Convenient, Reliable, Secure

!±8± Electronic Safe Locks - Convenient, Reliable, Secure

Security is as important today as it's ever been; perhaps more-so. Rising regional criminal activity, economic downturn, and the constant threat of natural disaster has people seeking personal accountability over the protection of their valuables. A safe is the most effective, practical way of guarding the material belongings that you care about, and the industry is constantly making improvements to cater to prospecting safe owners.

Arguably the most important feature on a safe is the lock. After all, without it, it would simply be a steel chest waiting to be emptied. Safe locks can be incredibly complex, and range in a variety of accessibility. Most common on smaller safes are keyed entry locks. On generally larger units, from personal gun safes to bank vaults, the security gamut is filled with a range of traditional combination locks and hi-tech biometric scanners. However, the lock that strikes the perfect balance between dependability and usability is the keypad-entry electronic lock.

Access to electronic locks, as mentioned, is nearly always governed by a keypad system, storing a numerical (in some cases alphanumerical) pass code - generally six digits in length. This allows the safe user to open the door significantly faster than the trusty, but slow rotating dial, while providing more accurate access security than the sharp, but imperfect biometric scanner.

While there are certainly sub-spectacular models on the market, many of them are constructed to stand up to the toughest of tests. Electronic locks listed in UL's (Underwriters Laboratories - security product testing leader) Type 1F Group are endorsed for approval by federal standards. While a lock of this caliber may be a bit overkill (both in price and function) for personal need, the possibilities for security are virtually endless.

To elaborate on the point of possibility, electronic locks open the door for more supplemental security integration than any other brand of safe lock in the industry. Many high-end models can be seamlessly integrated into alarms, motion detectors, video cameras, and remotely accessible locations. The boundaries of adaptable personal security can be pushed as far as you need them to go.

All of their strong suits aside, electronic locks certainly have a few relative shortcomings, particularly when stacked up to their mechanical counterparts. Though they simply run on batteries, which need to be changed very rarely, their lifespan doesn't hold a candle to a well-maintained combination lock (some 100 year old models are still functioning today). However, longevity remains a goal of high priority, and manufacturers continue to invest their efforts in improving resilience.

In conclusion, trusting an electronic lock to secure the valuables in your safe is a wise choice, as reflected by their proven dependability and ever-flexible versatility.
