		File No. 000-27026

Dear Mr. Craighead:

We have reviewed your filing and have the following comments.  We
have limited our review to only your financial statements and related
disclosures and will make no further review of your documents.  Where
indicated, we think you should revise your document in future filings
in response to these comments.  If you disagree, we will consider
your explanation as to why our comment is inapplicable or a revision
is unnecessary.  Please be as detailed as necessary in your
explanation.  In some of our comments, we may ask you to provide us
with supplemental information so we may better understand your
disclosure.  After reviewing this information, we may or may not
raise additional comments.

	Please understand that the purpose of our review process is to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or on any other aspect
of our review.  Feel free to call us at the telephone numbers listed
at the end of this letter.


Form 10-K for the fiscal year ended June 30, 2004

Item 7.  Management`s Discussion and Analysis of Financial Condition

Results of Operations:
General
1. In future filings expand the MD&A to discuss how the acquisition
of SaRonix or any other acquisitions, has impacted your operating
results and financial condition.
2. In future filings discuss how other key performance indicators,
such as, changes in volume or changes in prices, might affect your
earnings and cash flows, so that investors can ascertain the
likelihood of whether past performance is indicative of future
performance.
3. In future filings identify and disclose any known trends, events,
demands, commitments and uncertainties that are reasonably likely to
have a material effect on your financial conditions and operating
performance.  Refer to SEC Release Nos. 33-8350, 34-48960 and FR-72.

Gross Profit - Page 29
4. We noted that your net sales included sales of excess inventory of
$823,000 in fiscal year 2004.  Please address the following:
a. Tell us how the inventory that you later sold was priced - i.e.,
did you sell it at its new cost basis after write-down, or did you
realize a profit.
b. Tell us and revise future filings to disclose the impact of the
sales upon gross margin for the periods presented.
c. Explain to us in detail, the events and circumstances that arose
during the period allowing you to sell inventory that you had
written-off as obsolete.
d. Tell us the total inventory written-off to date, the amount sold,
the amount discarded, and the amount still on your books.
e. For any inventory still held, explain when and how you intend to
dispose of it.
f. We may have additional comments after reviewing your response.
5. Revise future filings to clearly describe the effects of price and
product mix changes as required by Regulation S-K Item 303(a)(3)(iii)
on your operating results.
6. In future filings, when you cite more than one factor in
explaining the change in a financial statement line item in MD&A,
please revise to separately quantify the amounts of the individual
factors cited, including offsetting factors.  For example, revise
future filings to quantify the impact of improved products mix, cost
reductions and the inclusion of SaRonix margins on your gross profit
margin.

Restructuring Charges - Page 29
7. We see that you incurred certain restructuring costs relating to
the lease of an unused facility during the fiscal year ended 2004 and
2003. Were these charges part of a formal plan approved by
management?  In future filings please provide in MD&A a detailed
discussion of each significant restructuring charge recorded pursuant
to SFAS 146 and EITF 94-3.  The following additional disclosures in
future filings would be useful to investors:
a. Describe the specific conditions or events leading management to
consolidate certain facilities, including specific factors related to
products, processes, customers and/or market conditions;
b. Identify significant actions taken and describe the expected
timing of those actions;
c. Identify the number and describe the nature of the positions being
eliminated;
d. Disclose the intended effects of your restructuring on your
financial position, future operating results and liquidity;
e. Quantify the anticipated and actual cost savings derived from your
restructuring efforts during the periods presented.
f. Ensure that your response demonstrates compliance with the
requirements of Question 15 of SAB Topic 5-P and SFAS 146.

Liquidity and Capital Resources - Page 29
8. Your Liquidity and Capital Resources discussion appears to be a
recitation of your cash flow statement in narrative form.  Please
revise in future filings to discuss those items which management
specifically believes may be indicators of the company`s liquidity
condition in both the short term and long term.  Refer to Item 303 of
Regulation S-K and FR-72.
9. We note that your inventory and accounts receivable balances
increased significantly for the fiscal year ended 2004 when compared
with the fiscal year ended 2003.  Revise future filings to discuss
the reasons for the significant increases in the 2004 balances and
the resulting impact as a source or use of your cash.
10. Revise future filings to discuss how you have funded, and plan to
continue to fund, the stock repurchase program.


Off-Balance Sheet Arrangements
11. We note that you did not disclose your off-balance sheet
arrangements. In future filings, include a separately captioned
subsection discussing off-balance sheet arrangements that have or are
reasonably likely to have a current or future effect on the company`s
financial condition.  Refer to Item 303 (A)(4) of Regulation S-K and
SEC Release No. 33-8182.
Contractual Obligation and Commitments - Page 31
12. Please supplementally reconcile the note payable amount of $1,251
you disclosed on page 31 to the amount you reported on the face of
the balance sheet on page 39.

Financial Statements

Consolidated Balance Sheet - Page 39

Intangible assets
13. In future filings, state separately the amount of the accumulated
amortization of intangible assets on the face of the balance sheet or
in a note thereto in accordance with Rule 5-02-15 and 16 of
Regulation S-X.
14. In future filings, provide all the disclosures related to your
intangible assets as required by paragraphs 45 and 47 of SFAS 142.
See Illustration 1 of Appendix C of SFAS 142 for guidance.

Note 1: Summary of Significant Accounting Policies

Revenue Recognition - Page 45
15. We see that your sales are, in part, made through distributors.
a. Supplementally describe the significant terms of your arrangements
with distributors, including but not limited to pricing, payment and
return policies.
b. Demonstrate to us that revenue recognition at shipment is
appropriate for transactions with distributors.
c. Clarify the accounting for any special arrangements with
distributors such as price protection, rights of return and other
discounts, credits or special terms.
d. Tell us how you considered paragraph 6 of SFAS 48.
16. We see that your products are distributed through independent
foreign and domestic manufacturer`s representatives, distributors and
agents.
a. Tell us whether your arrangements with these distributors or any
other parties ever include vendor consideration as described in EITF
01-09.
b. If so, tell us and revise future filings to describe the nature
and extent of that consideration and how you accounted for it.
Note 7 - Business Combinations - Page 49
17. We note that you refer to the use of an independent appraisal.
Please note that reference to independent experts will require that
the expert be identified and his consent included in future
registration statements in which you incorporate your Form 10-K.
Please consider for your future filings.

We will not object, however, if in future filings you deleted the
reference and attributed the ultimate responsibility of performing
the assessment to management.  In that case, you should clearly
disclose the method of determining the fair values of the assets.


Note 14 - Restructuring Charge - Page 54
18. We noted the table reflecting the restructuring charges you
recorded in 2004 and 2003, and payments recorded against the
liability during the same periods.  In future filings, expand the
note to address the following:
a. Describe in more detail the actions contemplated under each of
your restructuring programs, including the operations being downsized
or exited and facilities being closed, moved or streamlined.
b. Describe in more detail how your plan will impact your products
and processes and how your business and its operations will be
different upon completion of the plan.
c. Describe the timeline for completion of significant steps
including the anticipated timing of related cash payments to be made
in annual periods.
