In its second acquisition in a week, Teledyne Technologies Inc. said Friday it acquired the assets of Demo Systems LLC, which makes aircraft-data software.

Chief Executive Robert Mehrabian said Moorpark-based Demo Systems’ data loading and software products complement Teledyne’s aircraft-data transfer and flight-information-management systems. Teledyne of Thousand Oaks makes components and systems for aerospace, energy and power generation uses.

Demo, which had sales of $7.3 million in its last fiscal year, will be combined with the Teledyne Controls subsidiary.

“As aircraft avionics systems demand more complicated avionics software and data transfer, the addition of Demo Systems will help Teledyne Controls continue to provide hardware and software solutions for improved total aircraft information management,” said Mehrabian in a statement.

Teledyne on Monday said it bought Odom Hydrographic Systems Inc., a Louisiana maker of hydrographic survey instruments used in port surveys, dredging and offshore energy exploration. In October, it bought a marine-sensor manufacturer based in the United Kingdom.

Teledyne shares were up 41 cents, or 1 percent, to $40.43 in morning trading on the New York Stock Exchange.
