Difference Between Zigbee and Z Wave

With wireless home security systems, you’ll be able to come across the technologies or home automation standards known as Z-Wave and Zigbee. Just what are Z-Wave and Zigbee and how are they similar and different from one another? Both Z-Wave and Zibgee are known as mesh networks which mean that every node integrated in that system will act as a wireless source of data and as a repeater as well. The data from one node will continue to jump or hop from one node to the next node until it reaches the gateway router. Both Z-Wave and Zigbee are also commonly used by companies manufacturing wireless home security systems and other things such as HVAC control, home automation and other systems for security. These networks also use the same protocol known as low rate personal area network for a united physical layer.

Zigbee is different from Z-Wave as such because it uses the 2.4GHz frequency band which means that the hardware using it can be installed and used in any part of the world. However 2.4 GHz is a busy frequency and can be prone to interferences from Bluetooth devices and Wi-Fi. Z-Wave is different since it uses the 915 MHz ISM frequency ban. Z-Wave utilizes their own radio system made by Sigma Designs while Zigbee has several providers for their radio systems. Z-Wave has lesser interoperability hassles than Zigbee when it comes to this aspect.

Many users find Z-Wave has better interoperability and its easier to use products made with Z-Wave network. There are many industries that uses Z-Wave such as manufacturers of home automation, wireless security systems and providers of controls for lighting. With the Z-Wave protocol the compatibility concerns and the need for professional installers to install home automation systems are totally eliminated. The Z Wave protocol can communicate effectively with one another. The latest program from Z-Wave is known as the Z-Wave Plus.

Z-Wave Plus is the latest certified program by Sigma Designs made for consumers to easily identify products that has the latest Z Wave platform for hardware. It is also known as the 500 series or the fifth generation Z- Wave. It includes more and enhanced capabilities and features made to improve the experience for the users and for quick and hassle free installation and setting up.

Many wireless home security systems in the market right now are made with Z-Wave and one of them is the Aetherlink DIY camera which is built with the Z-Wave plus technology – the latest with the Z-Wave 500 series chip and module.

Benefits of the Z-Wave Plus with wireless home security systems:

• Extended RF range coverage67 percent more

• 3 RF channels can be operated in some locations for further immunity to interferences

• Improved bandwidth – 250 percent more

• Better battery life – 50 percent increase

• NWI – Plug and play installation (network wide inclusion)

• Compatibility with devices that operate under the older versions of Z Wave

The latest Z Wave Plus offer has several benefits that makes devices that create smart homes become more user friendly. Zigbee is also creating major changes with the ratification of their network known as Zigbee 3.0 by the end of 2015. These developments will require time to be realized by the end users as the surroundings with which they are placed also need to converge with it.

More Piano Rock Songs – New Wave 80’s Edition

Here are some of the most memorable piano songs and riffs from the New Wave 80’s:

New Years Day – U2 The old piano gets an unlikely boost from a guitar dominated band with this cut from U2’s War album. U2 give a simple piano – bass – drums riff the power that they give they’re usual guitar – bass – drums lineup. The Edge plays this riff on a Yamaha CP-80 which has an unusual, distinctive piano sound that you hear in other 80’s cuts from Peter Gabriel and Hall and Oates. The shorter stings of the CP-80 give a little more of a guitar like tone, only bigger. U2 also used the piano the great effect on another single The Sweetest Thing.

Up On the Catwalk & Alive and Kicking – Simple Minds Michael MacNeil from Simple minds was also a CP-80 user and it is the signature keyboard sound on Simple Minds most successful albums like Sparkle in the Rain and the massive Once Upon a Time. These 2 cuts showcase the piano starting with the octave lead part that kicks off the stadium rock of Upon the Catwalk. Alive and Kicking has a whole breakdown that features nothing but piano, unheard of in a number one hit.

Just Like Heaven – The Cure This song only has piano during the solo section but what a great, memorable part it is. The Cure was known for being an emotional band and the piano solo in this song just makes you want to get out your eyeliner and pictures of and ex-girlfriend and sit and weep in front on the mirror ’til your mascara runs.

Rush – Big Audio Dynamite This song is from the 90’s but BAD was built from the Clash who were from the 80’s (and 70’s for that matter) so BAD gets in. The reason this song gets included is because there is an entire piano breakdown in the 2nd verse. Pianos don’t get many of those.

Rock the Casbah Since we’re talking about the Clash I’d be loathe to forget about this huge hit for them. Listen closely to how the piano is what’s driving the song most of the time and making it rock, and the guitars are adding the flavor. Usually it’s the other way around.

Be Near Me – ABC This hit from ABC has a great piano riff that drives the chorus, in fact it almost is the entire chorus hook, that’s how catchy it is.

Head Over Heels – Tears for Fears There’s an epic piano riff that opens this song that was used for a very strange dance number in the movie Donnie Darko. Kinda similar, and just as catchy as the Be Near Me riff.

No One Ever is to Blame – Howard Jones Another CP-80 user Howard Jones was a pioneer of doing a one-man show using only a keyboard setup. People told him he was crazy but he made it work surrounded by a mountain of keyboards and his venerable CP-80.

The Fluid Shock Wave Principle

In this article I would like to introduce you to a fighting concept called the Fluid Shock Wave Principle. The Fluid Shock Wave Principle is emphasized in all of the counter strikes I use. It is not an unknown concept in the martial arts; this striking principle has been called the focus punch, the energy sink, the heavy hand strike, and many other terms relating to a “vibration” type of strike. Unfortunately, learning how to deliver such a strike often took a lifetime of constant practice, since few individuals understood the strikes physics or a dynamics. I will explain them to you in this article.

I began researching striking principles after studying pressure point control tactics as a special agent for several federal agencies. It was learned that motor points are more sensitive to strikes, which allowed all of the strikes forward momentum to dissipate into the target before starting the recovery. The analogy that is often used to describe such a strike is the action of hammering a nail.

The foundation of the fluid shock wave principle is based upon nerve motor points as targets and a method of striking which maximizes kinetic energy transfer. We know that nerves are one of the most sensitive types of tissues in the human body. This is especially true when stimulated by various types of pressure or strikes. We also know that when a nerve or nerve motor point receives an unusually high degree of energy, the nerve may become over stimulated and experience a motor dysfunction. Since motor points are composed of large muscle mass which is saturated with microscopic effector/motor nerve tissue, the potential for injury from a strike is normally limited to a bruise. Therefore, striking a motor point becomes an ideal target for liability concerns, and very practical tactically, since over stimulating a motor nerve stops resistive muscular action.

An important aspect of the fluid shock wave principle is the mechanical aspect of the strike itself. What a strike or impact is made of a target, energy is transferred from the energy source into the target. The degree of energy, (known as kinetic energy) which is dissipated into the target, will be dependent upon the velocity, the mass of the energy source, and the duration of the energy transference. The efficiency of the strike will determine the length of the motor dysfunction.

To generate an optimal fluid shock waves strike with the hand, leg, or impact weapon, I have made the following observations:

1. Velocity: to increase the velocity of a strike substantially enough to effect a motor dysfunction, is very difficult. Velocity must be double at a minimum to have a substantial effect on power generation.

2. Mass: in contrast to velocity, the mass behind a target can be substantially increased by attempting to strike with the total body weight. This is one of the secrets of the fluid shock wave principle. This can be accomplished by several methods. The first is to ensure that all of your joints are locked on impact. This is a principle called “energy leaks,” which describes how kinetic energy may be lost on the impact exchange. For example, if you allowed your wrist to buckle on a hand strike, energy will dissipate in the wrist instead of the opponent’s motor point. The reduction of kinetic energy will be substantial, and will dramatically affect the length of the motor dysfunction if it occurs at all. Therefore, all joints must be locked (not hyper extended) on impact.

The next important element in maximizing the mass behind a strike is the use of your total body mass. This is accomplished by placing the emphasis on rotating your hips, or axis behind the strike itself. In conjunction with locking all of the joints on impact, you can generate power based upon your body weight, instead of striking with just the weight of your limb another important element of the fluid shock wave principle, is the concept of energy duration or “time one contact.” During my study I have identified and learned measurements of the duration of the fluid shock wave itself. The length of energy transfer must exceed approximately 30 milliseconds to achieve a motor is dysfunction. Ironically, this is almost exactly the length of energy exchange that occurs naturally when you allow all forward momentum to stop before retracting a strike.

Technique considerations

You can incorporate the fluid shock wave principle into your defensive and offensive striking by combining motor points and the torso for targets, with the principle of striking. When striking I do not advocate striking to the head. Not the face, the head. The head as a target is comprised mostly of skin and bone, not muscle mass or sensory nerves. Therefore, strikes of any type to the head with a closed fist should be avoided if possible. This is a tactical consideration. For example, the head is generally a hard structure. You will receive severe hand injuries from striking an attacker on the head. Trust me, I have done it. This will disable you only infuriate the attacker.

A good philosophy on utilizing defensive counterstrikes is that strikes should be delivered to the torso or nerve motor points whenever possible. If you strike to the head it should be in the face with a Palm Heel strike or Hammerfist or with jabs to the eyes.

The targets of the special agent combat of system strikes are as follows;

Palm Heel strike: the Palm Hills strike was designed primarily to stop its edit and attackers forward momentum. This strike is delivered in a stiff arm motion, and can be targeted at the attacker’s face or checks. Generally, this strike is followed by straight punch to the torso.

Straight punch: the straight punch is normally considered the power hand strike. Although this strike can be delivered to the head, it is strongly recommended that this strike be delivered to the torso, specifically the solo plexus region.

Forearm strikes: forearm strikes are used when the subject attacker had deeply penetrated the reactionary gap, and the straight punch or palm heel strike cannot be used. Forearm strikes are generally very strong techniques and should be delivered to the torso. I also use them when striking the brachial plexus or side of the neck for what’s called a brachial stun.

Brachial stuns: the brachial stuns are, without any doubt, the most effective and reliable stunning technique within a special agent combative system. Brachial stuns were designed to replace the necessity of hand strikes to the head. This technique can be delivered with the back of the hand, the inside of the hand, the inside of the forearm, or the outside of the forearm.

Front thrust kick: like the palm heel, the front thrust kick is designed to stop an attacker’s forward momentum at the edge of the reactionary gap. The recommended target for this kick is the upper thigh lower shin. Attempting to kick any higher would normally result in the attacker grabbing your foot or your leg. Front thrusts are also very effective when targeted towards the attackers groin or knee.

Knee strikes: the knee strike is delivered to the attacker’s thigh, groin, abdomen, and face. Striking to the thigh creates a high level motor dysfunction to the attacker’s leg, and also creates a high-level stun. I have used this technique many times when trying to control an attacker. When I strike their thigh several times with a knee strike they lose function of that leg and go down usually holding their thigh and writhing in pain.

Angle kick: also known as the peroneal kick, is one of the most effective combative counter strikes. The angle kick is delivered mainly to an attacker’s thigh and knee. This technique will create a motor dysfunction that will often last 10 minutes or longer. The angle kick is also known to create a high-level stun that is only second to the brachial stun. The pain is often so intense, that attackers often believe that their legs are broken. The pain normally diminishes in approximately 20 minutes. Giving you plenty of time to escape.

Embracing this principle will give you much more powerful techniques that you can use to create your own reality-based self-defense system.
