AN INTRODUCTION TO:
Irwin Weitman, P.E.
-
BSEE - Columbia University.
-
MSEE - Polytechnic University.
-
Registered Professional Engineer in New York State since 1970.
-
Expertise in Industrial, Commercial, Military, and Space Electronics.
-
Full-Time Independent Consultant since 1985.
WHY YOU SHOULD RETAIN ME....
-
I have many years of successful product design experience
performed in a professional and ethical manner.
-
I will give you an unbiased opinion of your company's
product, or your competitor's product.
-
I will be totally candid with you and not abandon your
project once I start working on it.
-
I will achieve your new product's design at the lowest
total cost.
P.C. BOARD PROBLEM REMEDIATION.
(WPS0001)
Let me fix the
that somebody left you
with!
-
Crosstalk - Interference between circuits on P.C. Board.

-
EMI - Emitted radiation reduction.
-
Susceptibility to ( RFI) Radio Frequency Interference.
-
Problems related to manufacturing geometry sensitivity.
ANALOG CIRCUIT DESIGN.
(WPS0002)
-
Low noise, signal conditioning and
amplification.
-
Low current (battery) operation.
-
Discrete and/or integrated designs.
-
Spice analysis to verify extended temperature performance.
-
Servo and feedback control circuit design.
-
Hybrid circuit design and substrate layout.
-
RF circuit design including Phase Lock Loops up to 1Ghz.
-
High speed digital circuits (these are really analog).
-
Temperature compensation circuit design.
-
Analog function generation circuits for compensation of
physical parameters.
-
Digital function generation circuits for compensation
of physical parameters.
-
Extremely high impedance circuits.
ALGORITHM DEVELOPMENT.
(WPS0004)
-
If you have an instrument or product that must respond
accurately to the physical properties of some device that has a nonlinear
or semi-linear output, then it may be desirable or necessary to convert
this data to a form that produces an accurate output that you can reliably
use in your product. This data may also be affected by temperature, pressure
or some other environmental factor that needs to be accounted for.
This means that you need an algorithm built into your product.
-
A mathematical algorithm may be implemented in digital
or analog form. The choice is an engineering decision based on cost, speed
of execution, time to develop and other factors. I have performed
both types of designs many times, with exactitude.
RF CIRCUIT DESIGN.
(WPS0005)
-
Account for sensitivity to manufacturing geometry in the
final design.
INSTRUMENTATION.
(WPS0003)
-
Low noise signal conditioning and amplification.
-
Low current (battery) operation.
-
Discrete and/or integrated designs.
-
Spice analysis to verify extended temperature performance.
-
Servo and feedback control circuit design.
-
Temperature compensation circuit design.
-
Analog function generation circuits for compensation of
physical parameters.
-
Digital function generation circuits for compensation
of physical parameters.
-
Extremely high impedance circuits.
DESIGNS
FOR CONSUMER PRODUCTS.
(WPS0006)
-
Your millionth unit performs the same as your first.
-
Reliable designs developed for your intended customer in
his environment, with consideration for functionality and ease of use.
-
I can provide test procedures for your manufacturing,
incoming and outgoing inspection. My designs have no secrets from
you, so your own test engineers can develop test procedures if you prefer.
You get full documentation.
-
Experienced in designs for "Off Shore Manufacture" in
addition to domestic manufacture.
-
Designs for automated testing.
-
Designs that take into account the strengths and weaknesses
of your manufacturing process.
FROM MARKET CONCEPT
TO PRODUCTION.
(WPS0007)
-
Industrial experience working with marketing, sales, industrial
design, and production to develop products that are attractive to to the
customer and profitable for the manufacturer.
-
Expeditious methods and personal concern bring your product
to market quickly.
-
My library of vendor and technical resources minimize
the time spent searching for information needed to complete your project.
COMPLETE
DOCUMENTATION FOR MY WORK PRODUCT. (WPS0008)
-
Computer generated documents delivered in paper or file
form.
-
I can use your drawing format.
-
Or, if you choose, I can use my own drawing format which
I archive for future reference.
-
If your company does not have an established engineering
document control system for engineering documents provided by vendors or
outside consulting services or your own technical staff, then Cedar Engineering
Company can develop one for you. A practical, time proven method
can be customized to economically fit your needs.
DESIGNS
FOR HIGH AND/OR LOW TEMPERATURE.
(WPS0009)
-
After completion of the first pass design of a circuit,
I perform a computer simulation of the design over the temperature range
specified for operation of the product. Any marginal behavior is
corrected before a breadboard is produced.
-
I have designed numerous products for operation over the
full temperature range of -55 Degrees Celsius to +115 Degrees Celsius.
-

Kelvin. (The temperature of liquid Neon used for cooling.) Developed
a a $0.07 sensor to replace a $240.00 sensor that was needed in 300+ locations.

-
Avoidance of outgassing problems.
-
Avoidance of voltage breakdown in space.
EXPERT
TESTIMONY AND RESEARCH FOR PATENT LITIGATORS. (WPS0011)
-
