  • Publication number: 20060023742
    Abstract: A Wiegand Converter for generating a bi-directional data includes a Terminal Data Separator, a Switch Controller, a Bi-directional Switch to control the Input or Output Wiegand Data send through a Bi-directional Wiegand Data Line. The Received Data sent to Converter and Transmitted Data received From Converter are in recognized computer form such as ASCII. The unsecured Wiegand protocols can then be manipulated by a terminal or transmitted it via a secured form or different data communication protocols and reversed it back to an acceptable Wiegand form for controlling the devices to be located at remote sites or in separate compartments.

  • Patent number: 5326276
    Abstract: A connector assembly for use with a unitary daughter board having different contact pitch arrangements on the lower edge portion, includes two different contact pitch arrangement connectors lengthwise aligned and juxtaposed with each other for commonly receiving the lower edge portion of the daughter board. The connector of the high density contact arrangement includes an outer end wall having a recess at the top for functioning as a pivoting point of the rotative movement of the daughter board without interference thereof. A middle partition wall of the same connector has the curved surface thereof in conformity with the rotation path of the daughter board.
