                      (Unaudited)

1. INTERIM FINANCIAL STATEMENTS

The accompanying condensed consolidated financial statements
for the three and nine months ended September 30, 2004 and 2003 are unaudited
and have been prepared in accordance with generally accepted accounting
principles in the United States of America and in accordance with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles in the United States of America for complete financial
statements.  In the opinion of management, the unaudited condensed consolidated
financial statements reflect all adjustments, consisting only of normal
recurring adjustments, considered necessary to present fairly the financial
position, results of operations and cash flows of Scientific Technologies Inc.
(the "Company") and its subsidiaries for all periods presented.

To prepare these condensed consolidated financial
statements in conformity with generally accepted accounting principles,
management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities at the date of the financial
statements and revenue and expenses during the reporting period. Actual results
could differ from those estimates.

The results of operations are not necessarily
indicative of the results to be expected in the future or for the full fiscal
year.  It is recommended that these condensed consolidated financial statements
be read in conjunction with the Company's audited consolidated financial
statements and the notes thereto included in its 2003 Annual Report on Form 10-K.

The Company is substantially owned by Scientific
Technology Incorporated, a California corporation (the "Parent"). See
discussion of intercompany activities below.

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of
the Company and its subsidiaries after elimination of all significant
intercompany accounts and transactions.

STOCK-BASED COMPENSATION

Options to purchase 22,000 shares of common stock were
granted in the nine months ended September 30, 2004. The assumption regarding
the annual vesting of these stock options was 20% - 25%. The fair value of each
option grant is estimated on the date of grant using the Black-Scholes option-pricing
model with the following weighted-average assumptions used for grants in
2004: Dividend yield of 0.0%; expected volatility of 45%; risk-free interest
rate of 1.00% to 1.43; and expected life of four to five years.

4. RELATED PARTY TRANSACTIONS

The Company provides certain management
services to the Parent such as general management and accounting services. The
Company charges the cost of these services to the Parent based upon the amount
of time employees spent providing these services.  Management services charged
by the Company to the Parent for the three and nine months ending September 30,
2004 totaled $82,000 and $245,000, respectively.  Management services charged by
the Company to the Parent for the three and nine months ending September 30,
2003 totaled $77,000 and $271,000, respectively.

The Company leases essentially all of a 95,000 square
foot facility owned by an affiliate of the Parent. The Company also leases
another 25,000 square feet in another facility owned by the same affiliate.
Overhead costs are allocated primarily on the basis of square footage
utilized.

The Company utilizes a receivable from/payable to
Parent account to record activity including cash received, cash disbursed and
amounts owed to and receivable from the Parent for allocated charges. The net
effect of transactions with the Parent resulted in a receivable from Parent of
$737,000 at September 30, 2004. In addition, the Company is party to a capital
equipment lease of $181,000 at September 30, 2004 under which the Parent is the
lessor.

The Company is included in the consolidated tax return
of the Parent, but provides for income taxes on a separate return basis pursuant
to a tax sharing arrangement, which limits the Company's tax liability to the
amount payable to the Parent. Income taxes payable are recorded as a reduction
to the receivable from Parent account or as an increase to the payable to Parent
account.

The Company owns 50% of Aurora Technology Pte. Ltd
("Aurora"), in a joint venture with Amplus Communication Pte. Ltd.
Aurora, a Singapore manufacturing company, manufactures and sells sub-assemblies
and other components to the Company and others.   The Company is accounting for
this investment under the equity method and at September 30, 2004, the Company's
investment in Aurora was $525,000.

The Company operates principally in the United States. Sales
to foreign customers represented 13% of total sales in the three and nine months
ended September 30, 2004, compared to 12% in the comparable periods in 2003.

6. COMMITMENTS AND CONTINGENCIES

The Company offers warranties on certain products and records
a liability for the estimated future costs associated with warranty claims,
which is based upon historical experience and the Company's estimate of the
level of future costs. A reconciliation of the changes in the Company's warranty
liability follows (in thousands):

As permitted under Oregon law the Company has
agreements whereby the Company indemnifies its officers and directors for
certain events or occurrences while the officer or director is, or was serving
at the Company's request in such capacity. The indemnification term is for the
period that the officer or director is serving in such capacity or is subject to
any possible claim or action by reason of the fact that the Indemnitee was
serving in that capacity. The maximum potential amount of future payments by the
Company could be unlimited; however the Company has a director and officer
insurance policy that limits the Company's exposure and enables the Company to
recover a portion of any future amounts paid. As a result of the insurance
policy coverage, the Company believes that the estimated fair value of these
agreements is minimal.

7. RECENT ACCOUNTING PRONOUNCEMENTS

In January 2003, the Financial Accounting Standards Board
("FASB") issued Interpretation No. 46, or FIN 46, "Consolidation of Variable
Interest Entities, an Interpretation of ARB No. 51." FIN 46 requires certain
variable interest entities to be consolidated by the primary beneficiary of the
entity if the equity investors in the entity do not have the characteristics of
a controlling financial interest or do not have sufficient equity at risk for
the entity to finance its activities without additional subordinated financial
support from other parties. FIN 46 is effective immediately for all new variable
interest entities created or acquired after January 31, 2003. For variable
interest entities created or acquired prior to February 1, 2003, the provisions
of FIN 46 must be applied for the first interim or annual period beginning after
June 15, 2004. The Company believes it has no Variable Interest Entities and,
thus, the adoption of this standard did not have an impact on the Company's
financial position, results of operations or cash flows.



ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This interim report on Form 10-Q contains trend
analysis and other forward-looking statements within the meaning of Section 27A
of the Securities Act of 1933 and Section 21E of the Securities Act of 1934.
Such statements include expectations, beliefs, intentions or strategies
regarding future operating results, future expenditures, future cash
requirements and future industry conditions that involve risks and
uncertainties. The Company's actual results could differ materially from those
projected in such forward-looking statements as a result of many factors,
including, without limitation, those set forth under this section, the section
entitled "Business Factors" below and elsewhere in this report on Form 10-Q.

Results of Operations

(Amounts in thousands, except percentages)

Scientific Technologies Incorporated designs,
manufactures and distributes automation safeguarding and specialty sensor
products for the industrial control market. The Company's products include
safety light guards, profiling scanners, factory automation sensors, machine
safeguarding installation services, safety interlock switches, safety relays,
safety edges, safety mats, ultrasonic sensors, level and flow controllers,
pressure, displacement and velocity transducers, digital pressure gauges and
comparators and other electronic equipment supplied to industrial automation,
commercial and defense customers.

Sales for the three and nine months ended September
30, 2004 increased 4% and 9% to $14,604 and $44,876, respectively from $14,001
and $41,233 in the comparable periods in 2003. During the third quarter and
first nine months of 2004, we experienced increased safety product sales by the
Safety Products Group ("SPG"), project and service revenue declines,
respectively, compared to the same periods in 2003. The increased unit sales
growth by SPG was primarily related to an increase in the number of safety
products sold. The Automation Products Group ("APG") reported a sales decline of
3% for the third quarter of 2004 and an increase of 9% for the nine months ended
September 30, 2004 compared to the same periods in 2003. APG declines in sales
of level and pressure products in the third quarter were partially offset by
increased sales of ultrasonic products. The nine month sales growth was due to
increased sales of level products in the first six months of 2004.

Gross profit as a percent of sales declined to 32% and
38%, respectively, for the third quarter and first nine months of 2004 from 38%
and 41% in the comparable periods in 2003. This was primarily due to the write
down of a portion of certain intangible assets associated with the acquisition
of the Machine Services Division ("MSD"). Excluding the write down,
gross margins would have been 37% and 40% of sales, respectively, for the 2004
periods. SPG margin declined primarily due to lower sales combined with constant
fixed cost at MSD.  This decline was partially offset by higher margins at APG,
which resulted from a change in the mix of products sold to those bearing a
lower relative cost. Gross profit declined $581 and grew $229 to $4,701 and
$17,203 in the three and nine months ended September 30, 2004 from $5,282 and
$16,973 recorded in the same periods of 2003.

Selling, general and administrative expenses for the
three months ended September 30, 2004 declined 4% to $4,296 from $4,454 in the
same period of 2003. This was primarily the result of $59 of expenses associated
with the relocation of APG's PSI-Tronix Division to Logan, Utah in 2003. As a percentage
of sales for the three months ended September 30, 2004, selling, general and
administrative expenses improved to 30% compared to 32% for the same period in
2003. For the nine months ended September 30, 2004, selling, general and
administrative expenses increased slightly to $13,081 from $13,041 in 2003.
Increased SPG and corporate personnel costs of $375 were partially offset by the
lowered personnel costs of $228 at APG due to the PSI-Tronix relocation in 2003.
As a percentage of sales for the nine months ended September 30, 2004, selling,
general and administrative expenses improved to 29% compared to 32% for the same
period in 2003.

Research and development expenses declined 10% and
12% to $960 and $2,990 during the three and nine months ended September 30, 2004
from to $1,066 and $3,394 recorded in the comparable periods in 2003. This was
primarily the result of lower staffing levels, and reduced consulting expenses
in both 2004 periods compared to the comparable 2003 periods. As a percentage of
sales, research and development expenses in the third quarter and first nine
months of 2004, were 7% compared to 8% for the same periods of 2003.

Our effective income tax rate for the three and nine
months ended September 30, 2004 was 38%. We recognized a 38% benefit for income
taxes for the third quarter and first nine months of 2004, compared to a benefit
of 38% in the third quarter of 2003 and a provision of 38% for the first nine
months of 2003.  Income taxes payable or receivable are calculated on a stand
alone basis and are recorded as a payable to or receivable from our parent,
which, in turn files a consolidated tax return, including our accounts.

Contractual
Obligations

The Company has no raw material contracts exceeding one
year in duration.  In addition, the Company leases production, warehouse and
corporate office space as well as certain equipment under non-cancelable
operating lease agreements.  All building leases have renewal options and all
include cost of living adjustments.  No employees have employment agreements.
The following table summarizes the estimated annual obligations.

|                          | Payments due by period
|------------------------- | ----------------------
|Contractual Obligations   | Total                 
|Capital Lease Obligations | $   181               
|Operating Leases          | $3,118                
|Total                     | $3,299                

Liquidity and Capital Resources

(Amounts in thousands)

We had cash and cash equivalents at September 30, 2004
and December 31, 2003 of approximately $3,098 and $2,312 respectively.

For the nine months ended September 30, 2004, cash
from operations was $1,630 compared to $467 in the same 2003 period. This was
primarily due to a $2,002 non cash impairment charge and $1,962 of non-cash
depreciation and amortization expense, partially offset by increased inventory,
lower accounts payable, and increased accrued expenses. Our inventory balances
increased 16% in the nine months ended September 30, 2004, as a result of our
building inventory to support increased sales and  new product introductions. In
light of this, we expect a modest increase in inventory during the balance of
2004.

Available bank borrowings were $6,100, all of
which were unused at September 30, 2004. The Company's revolving line of credit
was renewed through June 30, 2005. We are in compliance with all loan covenants
under this facility, thus the full $6,100 facility is available to us, if
needed.

We believe that our existing cash and cash equivalent
balances and anticipated cash flows from operations will be sufficient to meet
our operating and capital requirements for at least the next 12 months.
However, revenues could decline below our expectations resulting in insufficient
cash flow from operations or we may require additional financing to fund new
product development, strategic investments in new markets, and strategic
acquisitions. As a result, we could be required, or could elect, to raise
additional funds during that period and we may need to raise additional capital
in the future. Additional capital may not be available at all, or may only be
available on terms unfavorable to us. With the exception of operating leases, we
have not entered into any off-balance sheet financing arrangements, we have not
established any variable interest entities, we do not have any unconditional
purchase obligations, nor do we have non-cancelable commitments for capital
expenditures.

Critical Accounting Policies

There were no material changes in any of our critical accounting
estimates or judgments during the third quarter of 2004.

Revenue Recognition

A majority of our sales are through third party
distributors, system integrators and original equipment manufacturers. Revenue
from product sales to customers is recognized upon shipment when shipped FOB our
plant or upon receipt by the customer when shipped FOB destination, if a signed
purchase order exists, the price is fixed or determinable, collection of the
resulting receivable is considered reasonably assured and product returns can be
reasonably estimated. Subsequent to the sale of the products, we have no
obligation to provide any modification or customization, upgrades, enhancements
or post contract customer support. Upon revenue recognition, we provide for the
estimated costs that may be incurred for product warranties. We estimate sales
returns and warranty costs based on historical experience and the best
information we have at the time we report our financial statements. Actual
results could differ from these estimates.

Sales agreements with our distributors in certain
instances provide stock rotation and price allowance rights. In accordance with
Statement of Financial Accounting Standards (SFAS) No. 48, paragraph 6, we
record revenue upon shipment to
distributors because at the time of shipment, we can reasonably estimate returns and price allowances based on historical experience, and because we have
visibility into the distributor's inventory.  Estimated
accruals for stock rotation and price allowance are
recorded at the time of shipment as reductions of sales. Price allowances are
accrued as a voluntary sales incentive in accordance with Emerging Issues Task
Force (EITF) 01-09.  Therefore, price allowances are accrued at the later of the
date of revenue recognition or when the sales incentive is offered to the
distributor.

Installation and engineering service revenue is recognized
when services are rendered, or when an identifiable portion of the contract is
completed, no significant post-delivery obligations exist and collection of the
resulting receivable is considered reasonably assured.  In certain cases, we
require the customer to provide a signed acceptance for the installation or
engineering services performed.  In these cases, all revenue is deferred until
we receive written acceptance from the customer and all other revenue
recognition criteria have been met.  As of September 30, 2004, the Company had
$55 in deferred revenue.

Inventories

We value our inventory at the lower of the actual
cost to purchase and/or manufacture the inventory or the current estimated
market value of the inventory. We regularly review inventory quantities on hand
and record a provision for excess and obsolete inventory based primarily on our
historical consumption and our estimated forecast of product demand and
production requirements. Demand for our products can fluctuate significantly. In
addition, our industry is characterized by technological change, new product
development, and product obsolescence that could result in an increase in the
amount of obsolete inventory quantities on hand. Our estimates of future product
demand may differ from actual results, in which case we may adjust the provision
required for excess and obsolete inventory. In the future, if our inventory is
determined to be overvalued, we would be required to recognize such costs in our
cost of goods sold at the time of such determination. Likewise, if our inventory
is determined to be undervalued, we may have over-reported our costs of goods
sold in previous periods and would be required to recognize such additional
operating income at the time of sale. Therefore, although we make every effort
to ensure the accuracy of our forecasts of future product demand, any
significant unanticipated changes in demand or technological developments could
have a significant impact on the value of our inventory and our reported
operating results.

Accounts Receivable

We perform ongoing credit evaluations of our
customers and adjust credit limits based upon payment history and the customer's
current credit worthiness, as determined by our review of their current credit
information. We continuously monitor collections and payments from our customers
and maintain a provision for estimated credit losses based upon our historical
experience and any specific customer collection issues that we have identified.
While such credit losses have historically been within our expectations and the
provisions established, we cannot guarantee that we will continue to experience
the same credit loss rates that we had in the past. A significant change in the
liquidity or financial position of any one of our customers could have an
adverse impact on the collectability of our accounts receivable and our future
operating results.

Valuation of Long-Lived Assets

We review long-lived assets for impairment on at
least a quarterly basis, or whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. The assessment of
possible impairment is based on our ability to recover the carrying value of the
asset or asset group from the expected future pre-tax cash flows (undiscounted
and without interest charges) of the related operations. If these cash flows are
less than the carrying value of such asset, an impairment loss is recognized for
the difference between the estimated fair value and carrying value. The
measurement of impairment requires management to estimate future cash flows and
the fair value of long-termed assets. Approximately 40% of our intangible assets
resulted from the acquisition of MSD, which is part of our SPG segment. As of
September 30, 2004, we have determined that approximately $2,002 of the recorded
value of the intangibles and goodwill associated with the MSD acquisition was
not recoverable and recorded an impairment loss of $2,002 to reduce the goodwill
and intangibles to their fair value. We will continue to assess the fair value
of our remaining intangible assets including those remaining associated with
MSD.

Business Factors

Because of the variety of factors and uncertainties
affecting our operating results, past financial performance and historical
trends may not be a reliable indicator of future performance. These factors, as
well as other factors affecting our operating performance, may result in
significant volatility in our common stock price. Among the factors which could
affect our future business, financial condition or operating results are the
following:

Our operating results may fluctuate.

We have experienced fluctuations in annual
and quarterly operating results and anticipate that these fluctuations will
continue. Our operating results may fluctuate for many reasons, including but
not limited to:

- variations in the timing and size of, or cancellations or reductions of,
customer orders and shipments;
- variations in the availability, cost and quality of components from our
suppliers, particularly from our single source suppliers and suppliers of scarce
components;
- competitive factors, including pricing, availability and demand for
competing products;
- constraints on our manufacturing capacity;
- variability of the product development and sales cycle with our
customers;
- variations in our manufacturing yields and other factors affecting our
manufacturing costs;
- changes in our sales prices;
- changes in the mix of products with different gross margins;
- failure to meet milestones under any significant development contracts;
- obsolescence of our component inventories;
- hiring and loss of personnel, particularly in manufacturing, research and
development and sales and marketing;
- product defect claims and associated warranty
expenses; and
- changes in the overall economic conditions that
we, our customers, and our suppliers experience.

The seasonality inherent
in our business could cause our operating results to fluctuate.

The industrial manufacturing equipment industry in
which we compete has historically been subject to seasonality. This is also true
with respect to European markets in which we compete where business activity
declines due to vacations taken in the summer months. This seasonality, combined
with other factors such as the variability in our operating results described
above, renders quarter-to-quarter comparisons of our results of operations
unreliable as indicators of our overall performance.

The market for our products is highly
competitive.

The market for automation safeguarding and specialty
sensors is highly competitive. Many competitors have substantially greater name
recognition and technical, marketing and financial resources than we have.
Competitive pressures could reduce market acceptance of our products and result
in price reductions, decreased revenues and increases in expenses.

Our business could suffer if we do not respond to technological
change and new product development demands of our customers.

The market for our products is characterized by changing
technology, evolving industry standards, changes in customer needs and new
product introductions. Our future success will depend on our ability to respond
to emerging industry standards, enhance current products, develop new products,
and achieve market acceptance of those products, all on a timely and cost-
effective basis. The introduction of new products also requires that we manage
the transition from older products in order to minimize disruption of customer
orders, avoid excessive levels of older product inventories and ensure that
adequate supplies of new products can be delivered to meet customer demands.

Our sales are dependent on independent distributors.

A majority of our sales are through third party
distributors, system integrators and original equipment manufacturers. These
resellers are not required to offer our products exclusively. We cannot assure
you that a reseller will continue to offer our products. In addition many of our
resellers are privately owned firms which may not be well capitalized, as was
demonstrated by the failure of two of our distributors during 2001. If our
ability to sell products through these third parties is impaired, our results of
operations would likely suffer.

Our international sales are subject to risks.

Our international sales may be disrupted by currency
fluctuations or other events beyond our control, including political or
regulatory changes. If our international sales were disrupted for any reason,
our revenue levels would decline.

Our business could suffer if we are unable to protect and enforce our
intellectual property rights.

We rely on a combination of patent, trademark, trade
secret laws and contractual restrictions to establish and protect proprietary
rights in our products and services. There can be no assurance that our patents,
trademarks, or contractual arrangements or other steps taken by us to protect
our intellectual property will prove sufficient to prevent misappropriation of
our technology or defer independent third party development of similar
technologies. Moreover, there can be no assurance that the technology licenses
granted to us from our parent company will continue to be available. The loss of
any of our proprietary technology could require us to obtain technology of lower
quality or performance standards or at greater cost, which could materially
adversely affect our business, results of operations and financial condition.
Also, competitors may develop their own intellectual property or technologies,
obtain their own patents, or challenge the validity of, or be able to design
around, our patents. The laws of certain foreign countries may not protect our
products, services or intellectual property rights to the same extent as do the
laws of the United States.

We may initiate claims or litigation against other third
parties for infringement of proprietary rights or to establish the validity of
proprietary rights. Similarly, our competitors may initiate claims or litigation
against us alleging infringement of their proprietary rights or improper use of
their intellectual property.  Litigation relating to intellectual property to
which we may become a party is subject to numerous risks and uncertainties,
including the risk of counterclaims or other litigation against us, and we may
not be successful in any such litigation.

Our operations have been and may continue to be negatively
impacted by uncertain global economic and political conditions.

Our business may suffer as a result of general economic
and political conditions in the U.S. and abroad.  In 2002 and 2001, there was a
rapid and severe downturn in the U.S. market and global economy. Terrorist acts
or acts of war could cause damage or disruption to us or to our suppliers and
our customers.  Fears of global recession, war, and terrorism may have serious
detrimental effects on the U.S. and global economies.  Such conditions could
further dampen consumer confidence and cause our customers to slow or cease
spending on our products.

We are dependent upon suppliers and outsourced
manufacturing, several of which are located outside of the U.S.  Disruption of
our access to these supplies and services, or problems with the quality of
supplies or services, could prevent us from filling customer orders and harm our
business.

The principal components of our
products are purchased from outside vendors. We generally buy components under
purchase orders, do not have long-term agreements with our suppliers, and we
generally do not maintain large inventories of components. Any termination of,
or significant disruption of, our relationships with the suppliers of our
product components may prevent us from filling customer orders in a timely
manner which could result in customer dissatisfaction and lost sales. We rely on third party manufacturers
for subassembly of products and for final assembly, quality assurance, and
testing of some of our products. These outsourcing arrangements and any future
outsourcing arrangements involve numerous risks, including reduced control over
product quality, delivery schedules, manufacturing yields, and costs.

Our ability to develop and
market our products is dependent upon our retention of certain executive
officers and other key personnel.

We are greatly dependent on
the ability to retain key management and technical personnel, and our future
success is highly dependent upon the personal efforts of our management and
technical personnel. The loss of services of any one of them could have a
negative effect on our business, financial condition, and results of operations.
Our success will also be dependent in part upon our ability to attract, retain,
and motivate highly skilled employees.  We may need to offer additional
compensation or incentives to attract and retain these and other employees.

If we are unable to
successfully develop our international sales efforts, our results of operations
may suffer.

We have to develop, integrate, and
expand our international distribution networks in an effort to increase
international sales of our products. We may not be successful in developing or
expanding the international distribution network or in marketing and selling
products in foreign markets. If the revenues generated by our international
sales are not adequate to recover the expense of establishing, expanding, and
maintaining an international distribution network, our business, financial
condition, and results of operations could be negatively affected. If
international sales become a more significant component of net sales, our
business could become more vulnerable to the risks inherent in doing business
internationally, including:

- Difficulties in managing foreign resellers;
- Longer payment cycles and problems in collecting accounts receivable;
- The effects of seasonal customer demand;
- Changes in regulatory requirements;
- Difficulties in meeting the requirements of different international product regulations;
- Risks relating to intellectual property rights;
- Increased expenses due to efforts to localize our product offerings;
- Export restrictions, tariffs and other trade barriers;
- Fluctuations in currency exchange rates; and
- Potentially adverse tax consequences and political instability.

The existence or occurrence of any one
of these factors could have a negative effect on our business, financial
condition, and results of operations.



Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The market risk inherent in our investments represents
the potential loss arising from adverse changes in interest rates.  We are
exposed to market risk in the area of interest rate changes impacting the fair
value of our investment securities.  Our policy is to invest primarily in money
market accounts and short-term investments held at financial institutions. We do
not have any derivative instruments in our investment portfolio. Due to their
highly liquid nature, our investments are subject to minimal credit and market
risk.



Item 4. CONTROLS AND PROCEDURES.

(a) 	As of the end of the period covered by this
report, our Chief Executive Officer and Chief Financial Officer have concluded
that our disclosure controls and procedures (as defined in Rules 13a-15(e) and
