Application software development for the following operating systems:

• Microsoft Windows (tm), all versions
• Linux, all versions
• Some DSP Realtime operating systems, including own OS developments

System level driver software development for the above operating systems, including:

• Audio Devices (standard / custom versions)
• Video Devices (standard board-level (i.e. chipset-specific) / custom versions, e.g. hardware codecs including compression)
• DSPs and peripherals for Realtime operating systems, including own OS developments (details on request)
• PC platform chipset level drivers for peripherals, e.g. printer devices, human interface devices, graphics devices, custom devices based on the USB port or older interface standards

Mathematical algorithmic level software development for the above operating systems, including:

• Digital audio tone generation and synthesis (owner of international patents)
• Digital audio effects
• Dynamic image object recognition (video data streams and static images), for security, insurance and entertainment applications
• Graphic design and multi-dimensional image processing (have a look at this web site opener logo, for an example)
• Image processing in general (industry precision manufacturing / military applications)
• Abstract mathematical solutions, like new domain transforms and filter algorithms, in most cases with the purpose to reduce the required processing power compared to existing solutions and / or the latency within real time applications

System level hardware development for the following platforms:

• x86 PC platform including chipset integration, and embedded computers
• PowerPC(tm) platform including chipset integration, especially smaller embedded computers at SOC (System-on-a-Chip) level
• Completely custom-level hi-end systems without general standards, e.g. processing systems at the Gigahertz clock level with 500 MHz clock DDR3-SDRAM devices
• Peripheral boards of all kinds, including PCI Bus and PCI Express Bus boards with high speed bus master DMA capability
• High precision analog sensor interfaces, battery powered, for medicine applications
• Wireless battery-powered data transmission interfaces, with standard or low latency-custom-protocols
• Low end hardware developments, e.g. robust microcontroller-based custom designs for industry automation

Chip level hardware development for the following technologies:

• Field Programmable Gate Array (FPGA) design, partially with later transfer to Mask fabricated Gate Arrays, from simple glue logic to self-developed specialized or general-purpose hi-end processing units (like the own "G8000"-processing system)
• Bus Interface Chips for PCI, PCIe (up to 2.5 Gbits/second per Lane, according existing standards)

Website design, especially without the, in most cases, overbloated standard tools libraries, including the following techniques:

• Strictly modular design of all website elements like headers, footers, with server-side module inclusion techniques, in most cases based on using the PHP language during the server-side assembly phase of a web page requested by the client browser
• Graphic design of all website elements with standard software and high-efficient self-developed tools
• Server-side programming techniques including full server-side graphic rendering of website objects (-this has been done for this website-), based on full PHP programming (Versions 4, 5), without isolating and sometimes not error-free user-level libraries, with tight and nested interaction to the client side based on JavaScript, and conventional HTML
• Asymmetric encryption of server-side code provides intellectual property saving without the need of client-side decryption (-this has been done for this website-)
• The server-side programming, of course, includes the complete off-line development with a virtual server installed on the local development PC (Gallitzendörfer currently uses the "Apache" web server, version 2.2.6; but note, this is not the server version of the provider where this website is hosted. This led to some additional experience about the differences between various server software versions.)
• All features of dynamic HTML design, including the display of temporary enabled page elements on request by mouse clicks at arbitrary selectable fields within the page (this allows the design of menus, property sheets, for example).

Last but not least:

• Language translations, in most cases of the own international patents from the German to the English language (and American English language - there are differences !). This is not as simple as it may seem because besides the usually complex technical subject, the formal conventions of the various patent institutions have to be observed which requires a special sense for language differences. Rainer J. Gallitzendörfer is a German native speaker - you may build up your own opinion about the quality of the language style used here on the web site.
