    - Discussion and Summary: Panasonic KX-TDE-100/200 PBX System

    This is Panasonics entry into the hybrid phone system arena. The term: hybrid, means that it connects to the stations (phone sets) and connects to trunks (phone company connections, i.e carrier connections) through both traditional circuit-switched techniques and through packet switched techniques.

    The packet switched approach is manifested as Voice Over Internet Protocol (VOIP). Panasonic has IP phone sets that connect to IP cards (that plug into the PBX cabinet). The connection from said card to the IP phone is through Ethernet. Panasonic will only connect to its own proprietary phone sets. You cannot plug in another vendors VOIP phone and expect it to work. Panasonic does also support remote locating of the IP phones so remote users can connect to the PBX through public IP cloud connections.

    The TDA-100 model is approximately a 100 port switch and the TDA-200 is an approximately 200 port switch. How many total stations and trunks you can get in one system depends upon which station and trunk cards you use.



    - Discussion and Summary: Ketufile Super Encryption Software

    The KetuFile family is strong 256 & 512 bit file encryption software that provides file security, data encryption, data security, using the AES encryption algorithm. The KETU software products are intended to provide security and file transfer for data files and executable files that are commonly found on a personal computer (PC). These include: text files, word processor files, spreadsheet files, image files, web page (html) files, etc. This software is designed to run on PCs that use the Windows(tm) operating system.
    The KETU products may be used to secure files (file encryption, data encryption, data security) for any purpose. These encryption software products have been designed to integrate well with Internet Email.

    All Ketu products use the advanced standard for encryption, the Advanced Encryption Standard (AES). AES allows encryption keys up to 256 bits.
    Certain Ketu products allow 512 bits, using double AES.

    NOTE: The KetuFile programs accept keys that comprise uppercase and lower case letters and numbers. This results in an approximately 4-fold reduction of key states. Therefore a so-called KetuFile 256 bit key has approximately 2^252 states. A so-called KetuFile 512 bit key has approximately 2^508 states.

    The approximate number of possible keys for a 256 bit KetuFile key ( 2^252 ):
    a Trillion x Trillion x Trillion x Trillion x Trillion x Trillion

    The approximate number of possible keys for a 512 bit KetuFile key ( 2^508 ):
    a Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion x Trillion

    A Trillion is defined (in the U.S.) as: 1,000,000,000,000



    - Discussion and Summary: MxDNA Approach To Conditioning Power - Removing Noise

    The MxDNA (Maximum Dissipative Noise Attenuation) products are fundamentally different from a filter type of product. The basic architecture of the MxDNA is to provide a low impedance path for the high frequency noise. The MxDNA provides a "path of least resistance" for the noise. Once the MxDNA has "captured" the noise power, it dissipates it. "Dissipate" means turning the noise power into heat. This heat is radiated from the product. It is important to note that once the noise power has been turned into heat, it cannot "get back" to "electrical noise". It is gone forever.

    Another important and fundamental difference in the MxDNA product architecture, is that it does not "carry" the power that it is conditioning. The MxDNA operates in parallel with the loads (equipment) that it is protecting from noise. The MxDNA simply plugs into a standard AC outlet and draws the noise on that AC line into itself - then dissipates it. This makes it especially easy and convenient to install the unit in a particular application. It also makes it very easy to test the effectiveness of the MxDNA in a particular setting.

    Another important aspect of this architecture of the MxDNA is that it can be deployed in a modular fashion. If a single MxDNA does not provide sufficient reduction of noise power, more units can be plugged into the same circuit.

    Finally, the intent of the MxDNA approach is to capture and remove utility noise power as early as possible. Capture it on while it is on the AC line. Capture and dissipate it before it enters the audio, or other equipment.


    - Discussion and Summary: Noble1 RF Reduce Cell Phone Radiation To Your Head

    How The RF Of The Cell Phone Tries To Get To Your Head

    The antenna of your Cell Phone is radiating Radio Frequency (RF) energy into the space around it. All RF energy has a wavelength. The wavelengths of Cell Phone RF are quite small, and are therefore referred-to as "microwaves". Some of this RF (microwave) energy couples into (gets onto) the ear piece wire that is going from your Cell Phone to the ear piece that is positioned in your ear. The wire, usually of a primarily copper construction, is quite happy to carry the RF. It can carry it reasonably efficiently up to your head. All that wire has to do, is to carry it more efficiently than the same RF would travel through the air to your head, and we have the situation where using a wired ear piece has worsened (increased) the radiation level at your head.

    We have made specific measurements of the coupling of the RF to the ear piece wire. Said another way, we have measured, in our microwave laboratory, how "well", how "much", the RF that is coming off the antenna, can get into the ear piece wire and therefore travel to your head. By the way, a "microwave laboratory" is a laboratory where various microwave frequencies can be generated and measured.

    We have found that, approximately 10% of the radiated power can couple into the ear piece wire. This is a fairly high number. Said another way, "it's a lot".

    By using the Noble1 device, this "a lot" can be reduced. The Cell Phone is, in effect, "trying" to get the RF to your head by traveling along the ear piece wire, but the Noble1 reduces the RF intensity. It reduces the strength of the RF energy. In a later section, on this page, will give specific figures for this reduction.
