REENGINEERING

In an effort to control cost increases on existing products, SOLUTIONEERING is actively engaged in redesigning, or REENGINEERING, already established layouts. The essence of REENGINEERING is product redesign through engineering analysis. The ultimate goal is to achieve major gains in cost efficiency, service and time.

EXAMPLES OF COMPLETED PROJECTS

1) A power line monitor which samples 3-phase voltage and current waveforms and computes RMS voltage, current, real and reactive power and power factor. It also monitors optically- coupled inputs and controls output relays. Commands and responses are communicated to a remotely located host computer. The circuit incorporates a single ADSP2105 DSP chip to perform both computation and embedded control functions.

2) Communications products which superimpose DPSK audio signals onto the 60Hz power line. These rugged outdoor units incorporate EPLD's and two 8051 series microprocessors, one for signal processing and the other for control and data acquisition. Power FET's are used to generate the class D transmitter signal. Design also incorporates two custom line coupling transformers. These units are used for meter reading, line voltage monitoring and breaker control.

3) PC-controlled, fully-automated equipment to test a proprietary computer board. This tester contains its own 8751 processor and read-write busses which interface to a parallel I/O card in the PC. The PC sends commands to special firmware in the unit being tested and to the fixture to determine if all options worked. Functions tested included parallel I/O, A/D conversion, byte- and bit-oriented serial communications. The mouse-operated PC software works similar to a software debugger which features breaks, loops and skips to aid in troubleshooting defective boards.

4) Protocol converter. Unit employs a microcontroller and modem. Messages transmitted and received at the modem port are 32-bits long, and the converted messages at the computer port are standard 8-bit characters. The micro samples the long messages and determines the state of each bit stimulating a special type of UART.

5) Board which digitizes RS-170 video signals and also reconverts stores digital images to RS-170 levels. The unit incorporates high-speed analog and digital circuitry. It is used to store pictures digitally and display marked pictures for video inspection systems.

6) Several temperature controllers with thermocouple, RTD or thermistor inputs and triac or relay outputs. Some types are inexpensive for general purpose resistive heating while others are complex, cascaded-loop devices for medical applications, and some were PC controlled.

7) Microprocessor controlled communication line leakage detector. Measures resistance to ground of individual wires in multi-conductor communication cables. Cables run for 30 or more miles along railroad tracks.

8) Power supplies. Inputs operates from the AC line or 12 to 125-volt batteries, outputs power electronics requiring 50 watts or less. Some are battery backed up. Saturated-core, switch-mode and linear technologies were used for isolation and/or regulation.

9) RF & Video processing. A system that can handle NTSC, C. Video, S. Video, SVGA and convert it to RGB to be used as an input for unique light source made by TI (Texas Instrument).

DESIGN SIMULATION CAPABILITIES

Time to market is a major factor when dealing with new product development. In order to identify design problems in advance, Solutioneering is offering design simulation services. These simulations are performed using CAD files and modeling techniques. The simulation covers the following areas:

1) EMI/RFI analysis for CE Compliance test.
2) Signal Integrity and Crosstalk analysis.
3) Current density analysis.
4) Thermal analysis.
5) Mechanical stress analysis.

These simulations are performed on a unix based computer system and are displayed in form of graphs, 3D presentations and numerical tables. Modifying the design based on the simulation results increases the possibilities to reduce the time to market.
