Safety above all - and we guard our computers with antivirus programs, firewalls, etc. Privacy is essential - and we... enter the Internet without giving a tiniest thought to protecting our private information. Your IP address, in other words your computer ID, as well as the location of your computer, the language your OS uses and other details are monitored and very often logged for future use at every site you visit while carelessly surfing the world wide web. Mask Surf Lite developers are absolutely sure your privacy is worth being protected and they guarantee it will be.

Mask Surf Lite lets you hide or mask your identity while surfing the web. It is achieved by using Tor, a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Your tracks on the way to your Internet destination are covered by directing your request through several servers. Each server along the way knows only which server gave it data and which server it is giving data to. As each server sees no more than one hop in the circuit, it becomes impossible to link the connection's source and destination. Now that you understand how it works, which is rather complicated, you should also understand that the friendly interface of Mask Surf Lite lets you protect your privacy in the easiest possible way. Mask Surf Lite is extremely easy to use. All you have to do is start Mask Surf Lite, click «Start anonymous surfing» and there you are, anonymously surfing the web.

Mask Surf Lite is an all-in-one online privacy solution. Besides anonymous surfing it provides you with the feature of cleaning browser traces on your computer so that your Internet activity stays anonymous on the inside as well. Mask Surf Lite is available for a small, one-time fee instead of monthly subscription payments, which is typical for anonymous services.

DipTrace is an advanced PCB design software application that consists of 4 modules: PCB Layout with efficient auto-router, Schematic Capture, Component and Pattern Editors that allow you to design your own component libraries. Besides being very simple to learn, this software has a very intuitive user interface and many innovative features. For instance, a schematic can be converted to a PCB with one mouse click. Advanced manual placement and auto-placement features allow to get acceptable placement in several minutes. The board designer can instantly renew the PCB from an updated version of schematic and keep all previous work without changes. PCB and Schematic can be compared at any design stage to ensure they are identical. DipTrace has a powerful automatic router. It can route a single layer and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. DipTrace also provides you with external autorouter support. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye. Accurate shape-based copper pour system with different possible fill types and thermals can be used to make planes or to reduce manufacturing costs. Other important features are Electrical Rule Check (ERC), Design Rule Check (DRC) and Net Connectivity Check - the functions that check connections in Schematic by different rules (pin type, short circuit, etc.), the clearance between layout objects, which ensures board accuracy, and connectivity of all nets not depending on how they are connected (with traces, thermals or shapes). DipTrace modules allow you to exchange schematics, layouts and libraries with other EDA and CAD packages. DipTrace Schematic Capture and PCB Layout also support popular netlist formats and spice. Output formats are DXF, Gerber, Drill and G-code. Standard libraries include 50.000+ components.

HS X.25 is a software library in C (supplied with full source code) which implements ITU-T recommendation X.25 - Interface between Data Terminal Equipment (DTE) and Data Circuit-terminating Equipment (DCE) for terminals operating in the packet mode and connected to public data networks by dedicated circuit.

HS X.25 internally at a lower layer interfaces to HsDL library. HsDL library is Data Link layer abstraction. When HS X.25 is ported into environment with LAPB or LAPD as data link layer, only HsDL module needs to change.

HsDL links directly to HsSock module (also included in this package) - Winsock interface component that provides reliable TCP transport services similar to LAPB / LAPD / HDLC.

HsX25 as provided to customer may be used immediately in X.25 over TCP (XOT) solution or it may be used with traditional LAPB or LAPD in which case only HsDL will need to be modified.

Main Features: * DTE operation * DCE operation * Multiple layer 2 links * 4095 VCs per link * SVC supported * X.25 version: ITU-T (formerly CCITT) 10/96 * outgoing calls * incoming calls * max packet lenght 1024 * all X.25 timer and counters implemented * interrupt packets supported * Statistics * Trace Function *

HsX25 as provided to customer may be used immediately in X.25 over TCP (XOT) solution or it may be used with traditional LAPB or LAPD in which case only HsDL will need to be modified.

DipTrace is an advanced PCB design software application that comes with PCB Layout module, powerful auto-router, Schematic Capture and Component/Pattern editors to design your own component libraries. Besides being very simple to learn, which is quite an accomplishment for an engineering software application, the software has a very intuitive user interface and many innovative features.
For instance, a schematic can be converted to a PCB with one mouse click. The board designer can instantly renew the PCB from an updated version of schematic and keep existing placement, routed traces, board outline, mounting holes and other work. DipTrace has a high quality automatic router, superior to many routers included in other PCB layout packages. It can route a single layer (bottom side) and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye.
Accurate shape-based copper pour system with different possible fill types and thermals can be placed to plane layer and manufacturing costs can be reduced by minimizing the amount of etching solution. Another important feature is Design Rule Check (DRC) - the function that checks the clearance between design objects, minimum size of tracks and drills, which ensures board accuracy. A feature comparing a PCB to a schematic helps detect possible design mistakes and correct them before prototyping.
Output formats are DXF, Gerber, N/C Drill and G-code. DipTrace allows you import DXF files in PCB Layout and Pattern Editor. Standard libraries contain 50.000+ components.

ELECTRA is a new generation of Shape-Based Autorouting software for PC boards. By contrast with traditional gridded maze autorouters, a shape-based approach allows for more efficient use of routing area and is more suited to handle complex design rules requirements of high density SMD or through holes boards and achieve the highest route completion rates. ELECTRA is designed to plug into an existing PCB CAD system environment that is supporting DSN file format such as Protel, P-CAD and other popular CAD systems including Cadsoft Eagle.
