Item 2.   Acquisition or Disposition of Assets.

     On March 6, 2000, HEI, Inc., a Minnesota corporation ("HEI"), completed its
acquisition of Cross Technology, Inc., a Minnesota corporation ("Cross"), in
accordance with an Agreement and Plan of Reorganization (the "Merger
Agreement"), dated as of February 25, 2000, between HEI, Cross and the
shareholders of Cross.  Cross, which is now a wholly owned subsidiary of HEI,
manufactures and markets wireless Smart Cards and other ultra-miniature radio
frequency (RF) applications.

     As provided in the Merger Agreement, each share of Cross common stock
outstanding was canceled and exchanged for 5 shares of HEI common stock.  In
total, HEI issued 600,000 shares of its common stock in exchange for all of the
issued and outstanding shares of Cross common stock.  The closing price of HEI
common stock on the Nasdaq Stock Market on March 6, 2000 was $13-1/8.  The
merger was structured as a tax-free reorganization for U.S. federal income tax
purposes, and HEI intends to account for the merger as a pooling of interests.

     Prior to the merger, no material relationship existed between Cross and HEI
or any of its affiliates, any director or officer of HEI, or any associate of
any such director or officer.  In connection with the merger, management of HEI
has recommended to its Board of Directors that the Board be expanded by one seat
and that Leonard Hadden, the former president of Cross, be named to fill that
seat.  HEI's Board of Directors has not yet acted on the recommendation.

     The foregoing information is only a summary and is qualified in its
entirety by the information contained in the documents filed as exhibits to this
Form 8-K.

Item 7.   Financial Statements and Exhibits.

     (a)  The required financial statements of Cross currently are not
          available.  The financial statements will be filed as soon as
          practicable, but no later than May 19, 2000.

     (b)  The required pro forma financial information related to the
          acquisition of Cross currently is not available.  The pro forma
          information will be filed as soon as practicable, but no later than
          May 19, 2000.
