The WBT is a Thin Client based on the Microsoft Windows CE embedded operating system. The Thin Client interfaces with a variety of host computers via the Telnet TCP/IP protocol stack. Responsibilities include analysis of project(s) to determine materials and man hours required to complete project(s), liaison to hardware manufacturer in Taiwan, implementation of enhancement(s) or bug fix(es), testing and transfer of updated code to Taiwan for incorporation into final build of WBT product.

June 2002 - August 2002: DriverSoft Consulting, Ltd

Formation, Inc. Moorestown, NJ

Port Windows/2000 device drivers APIs, System Services and applications to the Linux Operating Environment (see Formation, Inc. below).


March 2002: Formed DriverSoft Consulting, Ltd


January 2002 - September 2002: Independent Software Contractor

Formation, Inc. Moorestown, NJ

Developed Windows/2000 and Linux device drivers, APIs, System Services and miscellaneous application programs which monitor and control the Formation Network Server Unit (NSU). The NSU is a custom PC used in commercial airliners for in flight entertainment and email applications.

The device drivers expose the Formation Network Personality Card (NPC) to applications. The NPC contains various thermostats, power monitoring logic and general purpose I/O registers. The purpose of the NPC is to monitor environmental parameters and the power source to ensure that the NSU never suffers an uncontrolled shut down.


September 2001 - October 2001: Independent Software Contractor

Visara Inc, Raleigh, NC - Ported an NT kernel mode driver to Windows 2000. The driver supports a legacy 3270 coax card as well as a PCI 3270 coax card. These cards allow PCs to talk to IBM mainframes. Tasks include rewriting of specific modules to be Win/2000 compliant, creation of INF file for Win/98/2000 compatibility.


November 2000 - May 2001: Independent Software Contractor

Gamry Instruments Inc, Warminster, PA - port the Gamry Potentiostat Virtual Device Driver (VxD) to a Win32 Driver Model (WDM) device driver. Also update the application software to operate in the Win/2000 environment. The Gamry Potentiostat is a high performance/high precision electrochemical measuring device. Because of performance requirements much of what might typically be considered application level software is embedded in the device driver, making the device driver considerably complicated. Responsibilities include design of the WDM driver, creation of INF files, testing and interfacing with the existing engineering staff.
