During the development of an underwater laser imaging system, the client was experiencing multiple crashes and severe data corruption. From a previous effort done for the Coastal System Station (see above), Craftech was already familiar with the hardware and software that was being used, and therefore called in to research the problem and to provide a solution. After working with Raytheon (the hardware provider) extensively, the problem was identified within the kernel drivers. Craftech modified these drivers to insure smooth, reliable data transfers with no corruption of data.
-
Craftech also supplied a WDM Win2000 driver to replace the previous NT40 driver. This allowed the laboratory to upgrade the Oceanography Application user interface to its latest version, which operated only on Win2000 and XP.
-
Other driver enhancements, as requested. These included video data manipulation, and time stamping.

-
Provided technical expertise in resolving a number of problems related to the client’s older products
-
Produced a series of WDM video framegrabber and data-acquisition drivers to accommodate new hardware that had already been developed within the client’s company. These drivers provided a new direction for the company’s software development efforts.
-
Upon request, Mr. Mowatt stepped in as Software Development Manager and Mentor during a time of transition in the company’s affairs.
-
Provided direction to the client on using the Direct-X mechanisms to displaying video.
-
Implemented several drivers incorporating the concepts of USB, I2C, and Plug’n’Play. These drivers were used as templates for other technical personnel to use as a starting point for their new efforts.
-
Developed and maintained a customer development kit to allow the client’s customer’s to access the programmable features of the hardware. This involved many concepts including WDM device interface issues, Registry management, configuration, and installation issues.
-
Provided extensive consultations on the technical aspects of product definitions.
-
Developed proprietary scheme for flexible handling the large amounts of data that must be transferred from device to computer during high-speed video transfers. This required extensive knowledge of Win2000 DMA transfer mechanisms.
-
Prepared several product demonstration programs, which the client supplied to their customers.

The client's product involved mechanisms for sharing remote modem pools amongst a host of subscribers. A version of the product, which had not yet been released, was to re-architect several major functional pieces and move them from user-level code to kernel-level code where it was expected to substantially enhance the product’s performance. The performance increases were anticipated due to the elimination of many of the context switches that occurred between the user-level and kernel-level interactions. Craftech’s role involved the relocation of selected functionality from the product DLLs to the kernel-mode drivers.

A very interesting problem was put to Craftech – redirect audio data from the installed sound card to the LAN network. The audio data packets submitted to the network had to include proprietary protocol headers in order to be recognized by the receiving client software. This telephony application made use of TAPI, an Audio Compression Manager (ACM) driver, and a NT Wave driver. After the conceptual approach and software architecture were complete, Craftech’s primary responsibilities centered on the Wave driver, which included Winsock code to send audio packets to the network.

A division of the US Navy, CSS, contacted Craftech to develop a driver for a PCI remote telemetry device, which receives video image data via an underwater laser system developed by Raytheon. Raytheon did not have the expertise in-house to develop the required software. The driver had to program the onboard FPGA, transfer video data from hardware to holding buffers (system memory) in response to interrupts, and provide an interface for application programs to retrieve the video data. There were several interesting problems to solve on the way to a reliable solution.

Craftech received a commendation for its effort in this project.

Craftech was notified that several of the client’s older products were not working in the newly released Win98 environment. These older products were the key to a rather large sale that was to be made in Japan. Initial investigation indicated that the difficulties were within the driver portion of the product code. Because of the complexity of interaction between the product components (both hardware and software), the effort to identify and resolve the problems involved a team of 5 people, where Craftech served as technical lead.

Craftech was initially called in to generate a kernel-mode driver for proprietary PCI cryptography hardware. As the project developed, it became clear that Craftech would be able to contribute to the effort in quite a number of ways – including providing software architectural reviews, specialized test mechanisms, developing an API to their software development kit offered to their customers. Craftech has been regularly called in to solve a variety of problems for this client and enjoys a healthy continuing relationship.

The client manufactured proprietary storage devices that supported a larger hardware/software application. Craftech was to supply drivers for the devices, and provide an interface identical to that of a removable hard disk from the user’s point of view. Drivers, and removable hard-disk interface were supplied for all the current operating systems – Win95/98/NT/2000.
-

This project incorporated a specialized serial device, which had some very unusual protocol requirements. The standard serial drivers for each of the supported operating systems had to be replaced with alternate serial drivers written by Craftech. These alternate drivers tested each serial device it opened for the protocol requirements, and would enter special modes upon finding a relevant device. This application was used to control factory machines and process related equipment.
