Infrared and how it works

Infrared light is electromagnetic wavelength than visible light is between 700 nm and 1 mm. Infrared light is invisible light. When viewed with a spectroscope the light is infrared radiation to visible light on the electromagnetic spectrum with wavelengths on the wavelength of red light. With this wavelength the infrared light will be invisible to the eye but the resulting heat radiation still feels / detected. Infrared can be divided into three areas namely:


* Near Infrared………………0.75 - 1.5 µm
* Mid Infrared....……………...1.50 - 10 µm
* Far Infrared………………….10 - 100 µm


Direct sunlight contained 93 lumens per watt of radiant flux that includes an infrared (47%), visible light (46%), and ultra violet light (6%).

Infrared rays contained in the firelight, sunlight, radiators asphalt road vehicle or a reflection of the heat affected. Nerves on our skin can menginderai differences in skin surface temperature, but We Can not feel the infrared rays. Infrared rays are used to heat food. For example even at fast-food restaurant.
How can we utilize the principle of infrared to see the objects?
We make use of infra-red detectors every object that emitted infrared and will reflect or absorb infra-red so that the detector captures a different wavelength according to the temperature of the removed objects.
"Because the main source of infra red radiation is thermal radiation or heat, every object has a specific heat that we think are not even hot enough to radiate visible light can expend energy at infrared and visible, more heat can she radiates something more infrared radiation".
This is the basis of the detection of human body temperature and detection sensors to identify people stricken with bird flu or flu Firus pigs at international airports. Many objects absorb infra red radiation, but there is also reflecting in particular near infrared light, near infra red rays are not related to the temperature of the object unless the object is very hot temperature.
Infrared film (infrared detector) on the camera can see objects aided by sunlight and other light source inssue infra red rays from it then reflected and absorbed by object. we can get a color object with the help of reflection and the absorbed infrared object, the color of the object is combination of red color blue, green (RGB) and infra red.
Infra-red can be used also as a wave cariier can extend the distance limit of wave reception, but the transmitted wave must be line of sight (LOS) or straight-infrared can not turn if the transmit radius of vertical beam was blocked by an object even though it was transparent. This theory we apply in the digital wave modulation on the remote tv. Mobile is now integrated with infrared and blue tooth devices to communicate with the pc. Examples of its application of mobile application delivery from pc or vice versa, providing a record of phone number of the pc very much that it can not be stored in phone memory is usually used for broadcasting SMS.
What is the difference infrared rays with blue tooth?
The first, uses infrared light to emit a signal, such as tv remote, while the blue tooth uses radio frequency (RF) (2.4 GHz) for broadcasting signals.
second, infra red can not penetrate objects that prevented to reach the receiver or need reflection, because of its light. However, Bluetooth can penetrate objects such as walls, as far as not having a high skin depth.

What is Information Management ?

According to Wikipedia, Information management (IM) is the collection and management of information from one or more sources and the distribution of that information to one or more audiences. This sometimes involves those who have a stake in, or a right to that information. Management means the organization of and control over the structure, processing and delivery of information.

Get vendor neutral training in technologies and global best practices for managing and utilizing information assets at AIIM's Certificate Training Programs.

AIIM agrees with this definition. Information, as we know it today, includes both electronic and physical information. The organizational structure must be capable of managing this information throughout the information lifecycle regardless of source or format (data, paper documents, electronic documents, audio, social business, video, etc.) for delivery through multiple channels that may include cell phones and web interfaces. Given these criteria, we can then say that the focus of IM is the ability of organizations to capture, manage, preserve, store and deliver the right information to the right people at the right time.


Information management environments are comprised of legacy information resident in line of business applications, Enterprise Content Management (ECM), Electronic Records Management (ERM), Business Process Management (BPM), Email Management (EMM), Information Organization and Access (IOA), Knowledge Management (KM), Web Content Management (WCM), Document Management (DM) and Enterprise 2.0 (E2.0) technology solutions and best practices. Information management requires the adoption and adherence to guiding principles that include:

  • Information assets are corporate assets. This principle should be acknowledged or agreed upon across the organization otherwise any business case and support for IM will be weak.
  • Information must be made available and shared. Of course not all information is open to anyone, but in principle the sharing of information helps the use and exploitation of corporate knowledge
  • Information the organisation needs to keep is managed and retained corporately. In other words the retention and archiving, of information. If you save a document today, you expect it to be secured and still available to you tomorrow

Information management is a corporate responsibility that needs to be addressed and followed from the upper most senior levels of management to the front line worker. Organizations must be held and must hold its employees accountable to capture, manage, store, share, preserve and deliver information appropriately and responsibly. Part of that responsibility lies in training the organization to become familiar with the policies, processes, technologies and best practices in IM. That training is available through AIIM. www.aiim.org/training

Settings Gammu for Applications SMS Gateway

In this blog my article about the SMS Gateway. To initiate the SMS Gateway article about this I will discuss how setting Gammu. Have you ever heard of Gammu? Yes .. Gammu is a kind of service provided to build applications based on SMS Gateway. After we successfully build Gammu, then we can build SMS Gateway application with any programming language or platform, be it web based with a PHP or ASP or whatever, and also the desktop by using Delphi, VB or other.

The advantages of this Gammu is a opensource software available in source code or binary form it, so .. You do not have to worry about licensing. In addition Gammu is also available for Windows and Linux OS.
Issues related to ability, Gammu no doubt because in addition be able to send / receive SMS, Gammu can also send / receive MMS, backup / restore phonebook, as well as upload / download files to HP. In addition Gammu also support for more than 400 types of HP. You can view a list of HP that can be supported by Gammu in
Gammu Phone List Database.

To SMS Gateway, I suggest do not use hp NOKIA. Although the file listphone available, and can be recognized by Gammu, but most do not support the full NOKIA. Sometimes it can only send, but received SMS can not be read by Gammu, or vice versa.


Now we will discuss how to set up the Gammu on the Windows platform. To which the Linux please read alone in official website. In this article the discussion will be up to the installation service and run it.


First Steps (Download File)



Description: the file is a installer that I have modified and simplified to ease the installation process. Gammu that I use is version 1.25.


Step Two (Install Gammu)

By default the setup file above is installed, the file gammu located in the directory C: \ Gammu.


Step Three (Setting Configuration Gammu)

Once the file is installed Gammu, the next step is the configuration setting. This setting is required for purposes of adjusting the type of HP and port number to be used. How does the setting? The trick is to please edit the file 'GAMMURC' that exists in the directory 'C: \ gammu'. Edit the file using Notepad GAMMURC or the like.
And than .. which parts need changing configuration? OK .. parts that need to be changed is the

1.[gammu]
2.port =
3.connection =
port parameters were later filled with a port number corresponding location of your HP plugs. To find the port where you plug in your cell phone on your computer, please go to Control Panel -Phone and Modem Options - Modems . Well ... if your HP is plugged in the PC and the driver is installed properly then it will definitely appear on the port number.

Important!

If the Control Panel - Phone and Modem Options - Modem port does not appear, even though the drivers are installed, then you can still see the port through the Control Panel - System - Hardware - Device Manager - Ports (COM & LPT). If the port number appears in both the Control Panel - Phone and Modem Options - Modem and Control Panel - System - Hardware - Device Manager - Ports (COM & LPT) and it turns out different port number, then select the port number in the Control Panel - Phone and Modem Options - Modem.

Tip: HP should be every time you plugged into a PC, use the same USB port location, aka do not move around the plugs, because every change the plugs then the port number will vary. As a result you must change its settings GAMMURC repeatedly anyway because they have to adjust the port number.

Back at the config GAMMURC above, the connection parameters that are used to give information type of connection used to communicate with PCnya HP. Each type HP has the kind of connection is different. To know the type of connections on a particular type of HP, please download the file in here. The file is a compilation of what I do on the types of HP support with Gammu SMS Gateway.

Here is an example configuration when I use a modem GAMMURC Wavecom M1206B connected to the USB port com5.

1.[gammu]
2.port = com5:
3.connection = at115200

(Important: do not forget to sign: at the rear port)
If you use more than one HP is plugged into a PC, then you can add or change the configuration on the

01.[gammu1]
02..
03..
04. 
05.[gammu2]
06..
07..
08. 
09.dst..

Fourth Step (Test Connection)

The final step for gammu setting process is to test the connection between Gammu with HP / your modem. The move comes after the configuration settings done. The trick is to enter the folder 'C: \ gammu' on your Gammu directory via DOS PROMPT. Then type this command at a command prompt.

1.gammu identify

If after this command then appears dienter information about your HP, then the connection between your HP Gammu with success. If the response is not as expected, then check back to port number or type of connectionnya. Here is an example display that comes out when the setting is successful.

Setting Gammu


Step Five (Creating a MySQL Database for Gammu)
This step aims to set up a MySQL database to accommodate data needed Gammu SMS Gateway for SMS. Actually, not only MySQL that can be used, but can also SQL Lite or Posgre SQL. But ... in this article only for MySQL Honestly, because I am not familiar with the others.
The trick is to create a database with the name 'sms' or the other (up to) use your phpMyAdmin.
Then make the tables required by Gammu. Oops .. What table aja ya? Do not worry because Gammu dumpnya have prepared a file to create tables. Location of dumpnya files in the folder 'C: \ gammu \ mysql-tabel.sql'. Well .. please use the dump file to create the tables using phpMyAdmin.
In fact Gammu SMS not only be stored in the database, but also as a text file that is stored on your PC. But for the purposes of an SMS gateway it seems better to use the database as storagenya.
