       Registration Statement on Form S-1 filed August 29, 2022

       Cover Page

   1.                                                   Please disclose on your
cover page the price (and formula for determining it) at which
                                                        Lincoln Park will
receive your shares pursuant to the Purchase Agreement and the term of
                                                        the Purchase Agreement.
   2.                                                   We note you are
registering the 381,540 Common Shares previously issued to Lincoln
                                                        Park as consideration
for its commitment to purchase your Common Shares under the
                                                        Purchase Agreement.
Disclose the price per share at which the shares were effectively
                                                        issued to Lincoln Park
on August 5, 2022 and August 25, 2022, respectively.

3.       You disclose on the cover page that you have filed a separate
registration statement
         registering the issuance to and resale by certain third parties
unrelated to Lincoln Park.
         Quantify and disclose the percentage of your public float that will
become available for
         resale in the market pursuant to your registration statements in the
aggregate.
4.       Please revise the cover page to disclose that you have a majority
shareholder and will be a
         "controlled company" under the NYSE listing rules upon the date you
file your first
         annual report on Form 10-K pursuant to your side letter agreement with
the Public Sector
         Pension Investment Board ("PSP") at which time PSP is no longer
restricted from
         exercising its voting rights attached to your shares (unless the
agreement is terminated and
         you become a "controlled company" at an earlier date or PSP otherwise
disposes of its
         controlling interest in your shares after any applicable lock-up
period). Please ensure this
         disclosure identifies your controlling shareholder, discloses the
controlling shareholder's
         total voting power and cross-references a longer discussion of the
effects of your status as
         a "controlled company."
Prospectus Summary, page 11

5.       Please revise your prospectus summary to discuss the material terms of
the Purchase
         Agreement with Lincoln Park under a separate heading. Disclose the
floor price and the
         maximum number of shares that may be issued to Lincoln Park pursuant
to the Purchase
         Agreement.
Risk Factors
Risks Related to the Offering, page 17

6.       Disclose whether there is a risk that investors can engage in
short-selling activities and, if
         so, how any sales activities after announcement of a put may
negatively affect your share
         price.
The sale or issuance of Common Shares to Lincoln Park may cause dilution. . .,
page 17

7.       We note your disclosure of the Common Shares being registered for
resale by certain third
         parties unrelated to Lincoln Park pursuant to a separate registration
statement, which
         represents a substantial majority of your Common Shares outstanding as
of August 5,
         2022. Revise to clarify the percentage of shares you are concurrently
seeking to register
         for resale in the aggregate.
The terms of the Purchase Agreement limit the amount of Common Shares we may
issue to
Lincoln Park, which may limit. . ., page 18

8.       Advise whether there is a risk that the potential depressive effect on
your share trading
         price due to the substantial number of shares you are registering for
resale may also limit
         your ability to utilize the Purchase Agreement to enhance your cash
resources. For
         example, advise whether a decline in the trading price of your Common
Shares
         may affect the ability or rate at which Lincoln Park sells its shares
of your Common

         Shares and, as a result, may restrict the amount or timing of
additional financing you are
         able to obtain pursuant to the Purchase Agreement in light of the
Beneficial Ownership
         Limitation.
Dilution, page 56

9.       You disclose that the lower the price of your Common Shares is at the
time you exercise
         your right to sell Common Shares to Lincoln Park, the more Common
Shares you will
         issue to Lincoln Park pursuant to the Purchase Agreement, causing your
existing
         shareholders to experience greater dilution. Disclose the maximum
number of shares that
         can be issued pursuant to the Purchase Agreement to show the full
extent of dilution your
         existing shareholders may experience. Revise your risk factors to
better illustrate this
         dilutive effect on your share price as a result of the pricing formula
through which you
         will issue shares to Lincoln Park and the full extent of the dilution
your shareholders may
         experience.

Condition and
Results of Operations, page 89

10.      We note that the projected revenues for 2022 were $11 million, as set
forth in the
         unaudited prospective financial information management prepared and
provided to the
         DPCM Board and DPCM   s financial advisors in connection with the
evaluation of the
         Business Combination. We also note that your actual revenues for the
Six Months Ended
         June 30, 2022 were approximately $3.083 million. It appears that you
will miss your 2022
         revenue projection. Please update your disclosure in Liquidity and
Capital Resources, and
         elsewhere, to provide updated information about the company   s
financial position and
         further risks to the business operations and liquidity in light of
these circumstances.
11.      Please revise your discussion about how your registration statements
may impact the
         market price of the company   s Common Stock to highlight the fact
that Public Sector
         Pension Investment Board, a beneficial owner of over 50% of your
outstanding shares,
         will be able to sell all of its shares for so long as the separate
registration statement
         registering the issuance to and resale by certain third parties
unrelated to Lincoln Park is
         available for use.
Liquidity and Capital Resources, page 98

12.      In light of the significant number of DPCM public stockholders who
exercised their
         redemption rights prior to the business combination closing and the
unlikelihood that the
         company will receive significant proceeds from exercises of the
warrants because of the
         disparity between the exercise price of the warrants and the current
trading price of your
         Common Stock, expand your discussion of capital resources to address
any changes in the
         company   s liquidity position since the business combination. If the
company is likely to
         have to seek additional capital, discuss the effect of this offering
on the company   s ability
         to raise additional capital.

13.   Specify the "time period" referred to in the definition of an Accelerated
Purchase Date.
14.   Revise to disclose that the Purchase Agreement prohibits the company from
directing
      Lincoln Park to purchase any Common Shares if the closing price of your
shares is less
      than the floor price of $1.00.
Effect of Performance of the Purchase Agreement on Our Stockholders, page 162

15.   We note that your tabular disclosure showing the gross proceeds you would
receive from
      the sale of your shares to Lincoln Park begins with the assumed price per
share of $8.53,
      the closing sale price of your shares on August 25, 2022. However, your
common stock
      has recently traded below this price and the Purchase Agreement allows
for issuances to
      Lincoln Park at prices below $8.53. Revise to include a complete range of
possible
      purchase prices, including the number of shares that would be issued at
the floor price of
      $1.00.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
