ITEM 3.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

               On November 21, 2001, pursuant to an Agreement and Plan of
               Split-Off and Merger dated as of May 23, 2001 (the "Split-Off and
               Merger Agreement"), Johnson & Johnson acquired Inverness Medical
               Technology, Inc. ("IMT") in a merger transaction and,
               simultaneously, Innovations, formerly a majority-owned subsidiary
               of IMT, was split off from IMT as a separate, publicly-traded
               company (the "Split-Off and Merger"). At the effective time of
               the Split-Off and Merger, the outstanding shares of IMT common
               stock were converted into rights to receive shares of Johnson &
               Johnson common stock and shares of Innovations common stock, and
               the outstanding options and warrants to purchase shares of IMT
               common stock were converted into options and warrants to purchase
               shares of Johnson & Johnson common stock and options and
               warrants to purchase shares of Innovations common stock.

               As a result of the conversions described above in connection with
               the Split-Off and Merger, Ron Zwanziger acquired an aggregate of
               14,450 shares of Innovations common stock and options to purchase
               an aggregate of 282,485 shares of Innovations common stock, Janet
               M. Zwanziger acquired an aggregate of 2,600 shares of Innovations
               common stock, and Family Ventures acquired an aggregate of
               117,428 shares of Innovations common stock.


                                       5


               Pursuant to a Restricted Stock Agreement dated as of August 15,
               2001 (the "Restricted Stock Agreement") between Ron Zwanziger and
               Innovations, Ron Zwanziger purchased 152.741423722644 shares of
               Innovations common stock for aggregate consideration consisting
               of cash in the amount of $.15 and a Promissory Note dated August
               16, 2001 (the "Promissory Note") in the principal amount of
               $10,655,583.68 made by Mr. Zwanziger in favor of Innovations. The
               cash portion of the purchase price was paid with Mr. Zwanziger's
               personal funds. Copies of the Restricted Stock Agreement and the
               Promissory Note are filed as EXHIBIT 1 and EXHIBIT 2,
               respectively, to this Schedule 13D and are incorporated herein by
               reference. Immediately prior to the consummation of the Split-Off
               and Merger, Innovations effected a stock split with respect to
               the Innovations common stock (the "Stock Split"); as a result of
               the Stock Split, the 152.741423722644 shares of Innovations
               common stock owned by Mr. Zwanziger before giving effect to the
               Stock Split became 1,168,191 shares of Innovations common stock.
               See Item 6 below for additional description of the terms of the
               Restricted Stock Agreement and the Promissory Note.

               On December 20, 2001, Family Ventures purchased 500,000 shares of
               Series A Convertible Preferred Stock, par value $.001 per share,
               of Innovations (the "Series A Preferred Stock") for a purchase
               price per share of $30 in cash and an aggregate purchase price of
               $15,000,000 in cash. As of the date of this Schedule 13D, each
               share of Series A Preferred Stock is convertible into two shares
               of Innovations common stock, and the 500,000 shares of Series A
               Preferred Stock beneficially owned by Family Ventures are
               convertible into 1,000,000 shares of Innovations common stock in
               the aggregate. The conversion rate is subject to adjustment upon
               certain dilutive equity issuances by Innovations and events such
               as stock splits, stock dividends and the like with respect to
               the Innovations common stock. The source of funds for these
               purchases consisted of cash contributed by one of the members of
               Family Ventures and cash realized upon the sale of certain
               securities by Family Ventures.

               On December 20, 2001, Family Ventures purchased from Innovations
               a subordinated promissory note in the principal amount of
               $10,000,000 (the "Subordinated Note") and a warrant representing
               the right to purchase 27,594 shares of Innovations common stock;
               the aggregate consideration paid by Family Ventures for such
               purchase consisted of cash in the amount of $10,000,000. The
               source of funds for these purchases consisted of cash
               contributed by one of the members of Family Ventures and cash
               realized upon the sale of certain securities by Family
               Ventures.

               On December 20, 2001, Innovations granted to Ron Zwanziger a
               non-qualified employee stock option under the terms of
               Innovations' 2001 Stock Option and Incentive Plan for the
               purchase of 115,000 shares of Innovations common stock; such
               grant was made in consideration of his entry into the Lock Up
               Agreement described in Item 6 below. On December 20, 2001,
               Innovations granted to Family Ventures a warrant for the purchase
               of 385,000 shares of Innovations common stock; such grant was
               made in consideration of its entry into the Lock Up Agreement
               described in Item 6 below. Both the option and the warrant
               described in this paragraph are immediately exercisable in full.

               On December 21, 2001, Family Ventures purchased 156,263 shares of
               Innovations common stock from Zwanziger Associates, LLC, a
               Delaware limited liability company ("Zwanziger Associates"),
               whose managers are Ron Zwanziger and Janet M. Zwanziger. The
               aggregate consideration delivered by Family Ventures for such
               purchase was a cash payment to Zwanziger Associates of
               $1,815,267, constituting a per share purchase price of
               approximately $11.62. The source of funds for these purchases
               consisted of cash contributed by one of the members of Family
               Ventures and cash realized upon the sale of certain securities by
               Family Ventures.

ITEM 4.        PURPOSE OF TRANSACTION.

               All of the shares of Innovations common stock beneficially owned

               shares of Series A Preferred Stock and the options and warrants
               to purchase Innovations common stock that may be deemed to be
               beneficially owned by him and are reported in this Schedule 13D

               stock owned by a charitable foundation on whose board of
               directors Ms. Zwanziger and Ron Zwanziger along with three others

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

               As described in Item 3 above, pursuant to the Restricted Stock
               Agreement, Ron Zwanziger purchased 152.741423722644 shares of
               Innovations common stock for aggregate consideration consisting
               of cash in the amount of $.15 and the delivery of the Promissory
               Note. Pursuant to a Pledge Agreement dated as of August 16, 2001
               (the "Pledge Agreement") between Mr. Zwanziger and Innovations,
               Mr. Zwanziger pledged the shares purchased pursuant to the
               Restricted Stock Agreement to Innovations as collateral to secure
               his obligations under the Promissory Note. After giving effect to
               the Stock Split, the number of shares of Innovations common stock
               subject to the terms and conditions of the Restricted Stock
               Agreement, the Promissory Note and the Pledge Agreement consist
               of 1,168,191 shares of Innovations common stock (the "Subject
               Shares").

               Under the Restricted Stock Agreement, one-third of the Subject
               Shares (the "Four-Year Vesting Shares") are subject to a right of
               Innovations to repurchase unvested Subject Shares upon a
               termination of Mr. Zwanziger's employment with Innovations for
               any reason, including on account of death, disability, retirement
               or discharge or resignation for any reason, voluntary or
               involuntary, as described therein; the Four-Year Vesting Shares
               vest in forty-eight equal monthly installments commencing on
               November 30, 2001. Two-thirds of the Subject Shares (the
               "Three-Year Vesting Shares") are subject to a right of
               Innovations to repurchase unvested Subject Shares upon a
               termination of Mr. Zwanziger's employment with Innovations for
               any reason (including retirement or discharge or resignation for
               any reason), other than on account of death, disability,
               termination without cause or constructive termination, as
               described therein; the Three-Year Vesting Shares vest in
               thirty-six equal monthly installments commencing on November 30,
               2001. Upon Mr. Zwanziger's death, disability, termination without
               cause or constructive termination as described therein, all
               Three-Year Vesting Shares will vest in full. The purchase price
               per share for any such repurchase of Subject Shares by
               Innovations will be the purchase price per share paid by Mr.
               Zwanziger for the Subject Shares so repurchased.

               Mr. Zwanziger may not sell, pledge or otherwise transfer or
               dispose of any Subject Shares that have not vested as described
               above, except to certain of his family members, any trust for
               their benefit, any family limited partnership or family limited
               liability company of which the limited partners or members, as
               the case may be, consist solely of such family members, and the
               estate, heirs and distibutees of Mr. Zwanziger or any such
               permitted transferee.

               The principal amount of the Promissory Note (the "Principal") is
               due and payable on August 16, 2006, and interest on the unpaid
               balance of the Principal accrues at the rate of 4.99% per annum,
               compounded annually, and is payable on each anniversary of the
               date of the Promissory Note, commencing on August 16, 2002, and
               at maturity. Mr. Zwanziger is also obligated to pay the Principal
               and accrued interest thereon with the net after-tax proceeds of
               any sale by him of any of the Subject Shares. Mr. Zwanziger may
               also pay all or part of the Principal and accrued interest
               thereon by delivering shares of the Innovations common stock held
               by Mr. Zwanziger to Innovations for their fair market value at
               the time of delivery, provided that the principal balance and
               interest owed under any promissory note used to purchase such
               shares or secured in whole or in part by such shares have


                                       8


               been paid. Under the Promissory Note, Innovations shall have
               recourse against (i) any assets of Mr. Zwanziger up to (A)
               twenty-five percent (25%) of the Principal reduced by twenty-five
               percent (25%) of each payment of Principal made by the Mr.
               Zwanziger and (B) the full amount of accrued interest on the
               Principal and (ii) the Restricted Shares, which have been pledged
               pursuant to the Pledge Agreement. The Promissory Note was made
               by Mr. Zwanziger in favor of Innovations in replacement of the
               full recourse promissory note dated August 15, 2001 in the
               same principal amount made by Mr. Zwanziger in favor of
               Innovations and referred to in the Restricted Stock Agreement.

               Ventures may Sell any Innovations Securities at any time that
               Innovations is in default under the Mezzanine Loan Agreement. A
               copy of the Lock Up Agreement is attached to this Schedule 13D as
