Massachusetts-based Ambient Corp., which has struggled to sell its "smart grid" technology to power companies, will be up for sale at a Sept. 24 auction, Dow Jones Daily Bankruptcy Review reported today. Bankruptcy Judge Kevin Gross set a Sept. 22 bid deadline for buyers who want to challenge the first $7.5 million offer for the company. Ambient Corp. filed for bankruptcy on July 28, saying that the company has had a hard time finding buyers for its patented devices that plug into a utility's power grid to help the utility communicate with electricity users.
