Thank you, Richard. Revenues for the fiscal 2022 second quarter were $13.2 million, up 16.5% from the prior year quarter. As compared with the same prior year period, LRAD revenue was $10.6 million, up 8.4%. IMNS revenue was $1.9 million, up 128% and software revenue was $673,000, essentially unchanged from the prior year quarter. Gross profit margin was 52.9%, an increase of 640 basis points compared to 46.5% in the second quarter of fiscal 2021. Gross margin percentage was higher due primarily to a shift in product mix. We continue to expect gross profit margin to be plus or minus 50% for the full year, although there may be some fluctuations quarter-to-quarter. Operating expenses were $7.5 million, up from $4.7 million in the same period a year ago. The increase was largely due to a 46.3% increase in SG&A, primarily sales and marketing expenses from the addition of personnel for future growth, increases in noncash expense for amortization and share-based compensation and a 116% increase in research and development, principally engineers for product development. As a reminder, our fiscal 2022 business plan includes a year-over-year increase in operating expenses for strategic growth initiatives, targeted materially shifting our revenue mix toward a higher proportion of software revenue and expanding our margins. Net loss for the quarter was $492,000 or $0.01 per share, a decrease from net income of $262,000 or $0.01 per share in the fiscal 2021 second quarter. The change was mostly due to the increase in operating expenses to support the growth initiatives I just discussed. Adjusted EBITDA for the fiscal 2022 second quarter was $853,000 compared with $1.2 million in the prior fiscal year second quarter. We believe this information and comparisons of adjusted EBITDA enhances the overall understanding and visibility of our business performance. To that effect, a reconciliation of our GAAP results to non-GAAP figures has been included in our financial results release. Turning to our first half results. For the first 6 months of fiscal 2022, revenues were $23.8 million, up 23.4% from $19.3 million in the same period last year. Gross profit margin was 50.8% compared with 46.5% in the first 6 months of fiscal 2021. Gross margin percentage was higher due to a different mix of and higher revenue in the current year-to-date period. Operating expenses were $14.2 million, up from $9.1 million in the same period last year, again, largely due to a 48.6% increase in SG&A, primarily in sales and marketing expenses from the addition of personnel increased trade shows and travel, increased noncash expense for amortization and share-based compensation compared to the prior year and an 84% increase in R&D, specifically engineers for product development opportunities. Net loss for the first 6 months was $1.8 million or $0.05 per share compared with a net loss of $357,000 or $0.01 per share in the first 6 months of fiscal 2021. This decrease was primarily due to the higher operating expenses, partially offset by the higher gross profit in the current year period. Adjusted EBITDA for the first 6 months of fiscal 2022 was $441,000 compared with $922,000 in the prior year period. Cash, cash equivalents and marketable securities totaled $16.4 million as of March 31, 2022 compared with $20.7 million as of the prior year-end. Working capital totaled $16.8 million as of March 31, 2022, compared with $18 million as of September 30, 2021. Cash used in operating activities for the first 6 months of fiscal year 2022 was $3.1 million. This compares to cash provided by operating activities of $363,000 in the same period last year. The fluctuation primarily reflects an increase to inventory of approximately $3.2 million to hedge against supply chain challenges. We expect the inventory increase to convert to revenue through customer shipments this fiscal year. The company has an authorized share buyback program for up to $5 million through December 31, 2022. During the 3 months ended March 31, 2022, 142,442 shares were repurchased for $557,000. In the first 6 months, 259,310 shares were repurchased for $998,000. We may, from time to time, repurchase shares in open market transactions. However, investing in our business for future growth remains our primary objective for the allocation of capital. We would like to now open the call to Q&A. Operator, operator?
