EDUCATION BSEE - FLORIDA ATLANTIC UNIVERSITY Boca Raton, Florida 1981 Honors
EMPLOYMENT HISTORY Senior Electrical Engineer – 10-2015 to present - Independent Design Professional - Jupiter Florida Senior Hardware Engineer – 7/2013 to 9/2015 – congatec Inc. Worked on designing Type 10 and Q7 COM modules with 4GB DDR3 memory and GBE (GigE Ethernet). Interfaces include but not limited to: DDR3, USB 2.0 & 3.0, PCIe gen 2 & 3, I2C, SmBus, LPC bus, eMMC, SPI bus, LVDS, Display Port, HDMI, HAD (High Definition Audio), switching regulators, DC-DC regulators, etc. Performed high speed interface compliance testing for USB & Ethernet. Set up Cadence development environments in our design center. Performed DC-DC regulator EVT on COMe modules.
Staff Engineer – 5/2006 to 7/2013 – Cross Match Technologies; Palm Beach Gardens, Florida – Major contributor to the development of Avenger. Responsible for the Intel architecture and carrier board design as well as its implementation. Developed the hardware architecture for the SEEK product and a majority of the hardware design (HAD, USB, Ethernet, CF, SD etc). It is a portable multi-modal biometric acquisition device that runs Windows XP and is based on Intel Atom architecture. I designed multiple Biometric products based on USB 2.0 to be compliant with the electrical specifications of USB 2.0. I created a company OrCAD CIS database for CMT and trained the engineering staff on the intricacies of the Cadence Allegro tool suite. I am the in-house resource for doing high-speed designs. My extensive experience in controlled impedance stack ups and constraint driven designs has allowed for very low EMI footprints. I was the project leader for creating a critical demo system in 2 months, delivered on time and working. Worked on a research project for inductive power transfer to power portable products and charge Smart Batteries. I am currently the Lead Engineer working on a 3 rd Generation Intel Atom design integrating multi-modal Biometrics into a portable design capable of running Windows 7. Worked on Freescale ARM board layout.
Principle Electrical Engineer – 5/2000 to 5/2006 – DRS TS INC./ WALKABOUT COMPUTERS INC/; West Palm Beach, Florida - I was a member of a development team that designed 3 generations of ruggedised tablet (pen and touch based) computers based on Intel chipsets. I use OrCAD CIS and Cadence Allegro Performance for circuit board layout and flex-circuit design. I implemented an OrCAD CIS database for use in our Centrino design. We brought up our 1 st pass board in less than 1 week running windows. I designed many OEM modules for integration; GPS, GPRS and Bluetooth. I designed many of the 14 power supplies in the Centrino design, Cardbus interface, controlled impedance calculations and many others. I was an in house ISO 9001-2000 auditor and wrote the Engineering ISO Process.
Electronic Project Leader – 7/1987 to 4/2000– GE MARQUETTE MEDICAL SYSTEMS; Jupiter, Florida - I was responsible for all of the electronic design in our division’s products. My responsibilities included systems design, circuit design and CAD work necessary to produce all types of printed circuit boards. I was responsible for design through release of electronic products to production. I supervised the work of other electrical engineers. I designed a video graphics controller for VME bus using PALS, high-speed logic, VRAM, DRAM and a TMS34010 graphics controller. I designed hardware that would allow single pixel horizontal scrolling. The back-end logic in this design runs at 63MHz. I designed a VME interface/controller for a thermal printer using a TMS34010 graphics controller. This design was implemented with FAST logic, PALs, VRAM and DRAM. This design multiplexed the serial data from the VRAM array into a single serial stream for the thermal print head. It also provided the stepper motor controller clock and control lines. I designed a hybrid VME/ISA back plane that allowed a Intel processor be a slave on the VME bus. This allowed for the use of standard off-the-shelf ISA peripheral cards (SCSI HD controllers, network interfaces, keyboard etc.). I designed a high-speed video buffer/driver for driving multiple RGB analog monitors from one source. ..I designed a proprietary back plane that allowed interface of other divisions products. This back plane incorporated a DC-DC converter and an RS-422 interface to a main console.
I designed a low power 16 channel Intra-cardiac ECG analog signal acquisition board set with A/D, FLASH memory and Motorola 56001 DSP. This board communicated using the high-speed serial port on the DSP. I designed a second DSP board, which communicated with the first via the high-speed serial port (DSP-DSP). This board has high speed SRAM, FLASH memory and D/A converters. It also has a proprietary serial interface that connects to a proprietary back plane (previously mentioned). ..I redesigned the video controller and the thermal printer controller using the latest CPLDS, FPGAS and fine pitch SMT. This allowed combining three 6U VME cards onto one 6U card. This card was backward compatible with the previous generation and could be configured to replace any or all of the three cards it replaced. I designed a VME slave processor board to replace one that we were using from another product line. The new card was fine pitch surface mount and used CPLDS and SRAMS along with FCT bus logic. There was a dual port memory scheme using bus request/grant. This board also incorporated a DUART with an RS-422 interface to communicate with the remote signal acquisition system. This design fit on a 3U card. I designed a master processor board to replace one that we were using from another product line. It boasted doubled clock speed and double memory at a fraction of the original. It has one in-system programmable logic device on it for all of the logic. There is also FLASH memory and a DUART with a RS-232 interface for debugging. This design fit on a 3U card. I combined the master and slave processor boards onto one board using one large (240 pin pqfp) in system logic device. There is now enough FLASH memory for all five of the VME processors. This board is in production now. I redesigned a thermal printer controller to reduce EMI and enhance manufacturability. This is a single board with very high density SMT using one interface to program multiple ISP logic devices. I used Synario and State Cad design environments for logic design and am in the transition to VHDL. I use PCAD, Veribest and OrCAD for schematic capture. I used CANVAS for mechanical illustrations and MS WORD for windows for text documentation, Micro Soft Project, Micro Soft Source Safe, Micro Soft Excel, and Visio just to name a few. I work closely with contract manufacturers and off site production personnel. I was a member of the team that achieved ISO9001 certification for our group and the CE mark for our product. I am familiar with GMP (good manufacturing practices).
Project Engineer - 9.84 to 7.87 - EMERGENT TECHNOLOGY CORP., Boca Raton, Florida Began employment with ETC just after the company was incorporated. Project accomplishments included designing and developing a three-channel FM modem for data base collection. Performed ESD testing of P.C. based product and implemented changes to decrease susceptibility. I was the project engineer for a portable 64180 processor based data acquisition unit. I worked with vendors developing custom components for this system; developed the packaging concepts, hardware user interface, power control circuitry to maximize battery, and wrote the design specification for the unit.
Development Engineer - 11.81 to 8.84 - LITTON DATAMEDIX, Boca Raton, Florida Redesigned and implemented the main memory (EPROM) of the PECGASYS product - a Z80 based intelligent terminal system. Designed and implemented a pseudo paged memory (static CMOS), for the AMU - a NSC800 based ambulatory data acquisition system. Performed experiments and extensive testing to reduce the AMU’s susceptibility to E.S.D., resulting in changes to internal shielding and system design. Performed all system internal interconnection work (selection, test & documentation) on the Guardian Telemetry unit. Developed a method of detecting pattern sensitivity in 64K static RAMS which were undetected by the factory. Product engineer for PECGASYS/AMU system. Supported other product lines.
