Net income for Interlink Electronics Inc. dropped 92 percent in the third quarter when compared with the previous year. The Camarillo-based developer and manufacturer of electronic signature and e-notarization products reported net income of $121,000, or $0.01 per diluted share, on revenues of $7.2 million for the quarter ending Sept. 30. For the same period a year ago the company had net income of $1.6 million, or $0.12 per diluted share, on revenues of $4.7 million. The difference between the two quarters was attributed to Interlink taking a $6.2 million gain in the third quarter of 2007 from the sale of two of its business units. For the nine month period, Interlink reported a net loss of $2.5 million, or $0.18 per diluted share, on revenues of $19.7 million.
