Regex Expression Updated for alphaNumeric or Numeric sequences

VB.NET 2003

Right now the regex below is not pulling these number sequences (below)
Question:
1. I did not know if some of the regex expressions I have here will work.

' code ====================================================
With dbDataSet.Tables("tblData")
            For Each dbRow As Data.DataRow In dbDataSet.Tables("tblData").Rows

  Dim input As String = dbRow.Item("fldDescription")
 Dim pattern1 As String = "(\s|^)(\d\w{3,}|\w(?=\w*?\d)\w{3,})(\s|$)" '4 or more in Digit/AlphaNumx 3 in length
'Dim pattern1 As String = "(\s|^)(\d\w{3,})(\s|$)"  '4 or more in Digit/AlphaNumx 3 in length
'Dim pattern As String = "(\s|^)(\d{4,})(\s|$)" '4 or more in length
'Dim pattern As String = "(\s|^)(\d+)(\s|$)" ' WORKING for anynumber
'Dim pattern As String = "(\s+\d+\s+)"
               Dim mc As MatchCollection = Regex.Matches(input, pattern1)
               Dim output As String = ""
                Dim trimStr() As Char = {" "c, ":"c}
                For Each m As Match In mc
                    output &= m.Groups(0).Value & " : "
                 
                Next
                ' Remove the last " : " in the output string.
                dbRow.Item("fldMfrnum") = output.TrimEnd(trimStr)
                         Next
