Developed software to interface cellular radios to public terminals. This software established wireless data connections and managed data transfer sessions using CSD and GPRS. Developed firmware for sending text messages using a cellular radio. This included driver firmware for text entry on a 10-key keypad using multi-tap.
Designed and developed smart public telephone products.
Modified the firmware of an inkjet printer to convert it into a two axis printer. I also worked on the mechanical design and constructed prototypes.
Created a Visual Basic program to acquire data from eight vacuum chamber instruments through serial communications ports and create an output file for import into spreadsheet. The program provided inputs for sample rate and the duration of the experiment. Required learning and working with multiple proprietary protocols and various serial standards.
Designed and developed the firmware for monitoring the volume of fluid flow through dispenser valves. The module stores the data and reports it periodically through a serial interface. The module can also control outputs to valves in response to input conditions.
Developed a Windows product for an insurance company to replace their DOS product. Used Visual Basic for the front end and Novell Btrieve for the database.
