[Tex/LaTex] Wedge with vertical bar

math-modesymbols

I'm making a summary sheet of a course in LaTeX. There are, however, I have no idea how to draw two of the symbols. One of them is some sort of \wedge with a vertical bar through it, the other a \vee with a vertical bar through it, as shown below:

Any ideas how I could compose such a symbol?

This overlaps three things: wedge/vee, shortmid, and shortmid raised to a correct height. The numbers suit cm and lm fonts, for other fonts they might need to be modified.

See here for a quick course on \ooalign.

\documentclass{article}
\usepackage{amssymb}

\makeatletter
\newcommand\@@vertwv[3]{\mathop{\ooalign{%
  $#1#3$\cr
  \hfil$#1\shortmid$\hfil\cr
  \hfil\raisebox{#2}{$#1\shortmid$}\hfil\cr}}}
\newcommand\@vertwv[1]{\mathchoice
  {\@@vertwv{\displaystyle     }{0.38ex}{#1}}%
  {\@@vertwv{\textstyle        }{0.38ex}{#1}}%
  {\@@vertwv{\scriptstyle      }{0.28ex}{#1}}%
  {\@@vertwv{\scriptscriptstyle}{0.21ex}{#1}}}
\newcommand\vertwedge{\@vertwv\wedge}
\newcommand\vertvee  {\@vertwv\vee  }
\makeatother

\begin{document}

\[ a\vertwedge b \neq a\vertvee b \]
\[ \textstyle a\vertwedge b \neq a\vertvee b \]
\[ \scriptstyle a\vertwedge b \neq a\vertvee b \]
\[ \scriptscriptstyle a\vertwedge b \neq a\vertvee b \]

\end{document}
