Revenues from these sales during fiscal 2012 were used to fund the Company's planned increase in research and development that began in fiscal 2011. This increased internal product development was focused on the development of new products to provide platforms for future growth and a basis for collaboration with OEMs.
TCC initiated the development of a low cost, battery-powered, pocket encryptor to be compatible with our DSP 9000 system and capable of interoperating with essentially all VHF and HF radios during the year. This encryptor, called the HSE 6000, is designed to respond to the many customer requests for a man-borne solution that provides universal encryption capability. The development occurred during 2012 and the HSE 6000 is now available as a commercially available solution for military, border patrol, and police forces.
TCC also completed development of new DSD 72A-SP equipment upgrades that allow customers to use new radios, multiplexers and switches in its 2012 fiscal year. In 2011, a new multi-interface system designed to give users the capability of matching a single encryptor to a multiple interface radio was successfully tested by a major user. Procurement of this system upgrade was expected in 2012 but, as mentioned above, has been delayed due to political unrest. Current expectations are that the procurement will proceed in 2013.
For future military network security requirements, TCC has developed a very high-speed version of the DSD 72A capable of speeds of 155mbs and 622mbs (STM1 and STM4) over fiber optic and electrical interfaces. Customer field tests of TCC's new STM encryptors were successfully completed in fiscal 2012 and we expect that users of the DSD 72A system will consider these devices for their upcoming network expansions.Research and Development During the years ended September 29, 2012 and September 24, 2011, the Company spent $4,421,000 and $3,530,000, respectively, on internal product development. In fiscal 2012, the Company's internal product development expenses were higher than prior years but in line with its planned commitment to research and development, and reflected the costs of product testing and production readiness efforts. It is expected that development expenses will decrease by about 25% in fiscal 2013 as compared to fiscal 2012.
