The provider of data and voice solutions earned $4.6 million, or 12 cents a share, on sales of $43.3 million. Results were helped by a $1 million tax-expense adjustment.

Taser International ( TASR) rose 2% after the company said that a respiratory study indicated that subjects were able to breathe during a 15-second exposure to the company's Taser X26 stun gun. The study, which is being conducted by a teaching hospital in the Midwest and partially funded by Taser International, used a Food and Drug Administration-approved pulmonary function measurement device to measure breathing ability in subjects who received three five-second discharges with a one-second break in between each five-second cycle. A majority of subjects exhibited higher breathing rates and volume during the stun exposure than at resting state, the company said. "The results from this study should be extremely helpful in addressing concerns related to the effects of prolonged or multiple exposures to stun devices," Taser said. Shares were trading up 16 cents to $7.30.

Shares of Standard Microsystems ( SMSC) rose 16% after the chipmaker posted second-quarter results that topped forecasts and predicted third-quarter results would easily exceed estimates.
