Title: System for the secure storage and transmission of data
Inventor: SOLTESZ JOHN A
IPC: G06K19/10
Filed: 1991-07-02
Abstract: A system for the secure storage and transmission on data utilizes a visual algorithm to encode sensitive data in a secure manner on a data carrier. A camera (2) digitizes the image of a subject (4).  The camera output is received at the encoder (6), where it is fed into a scrambler (8) and a transmitter (10).

Title: Fire-Rated Corner Guard Structure
Inventor: NICHOLAS JOHN D
IPC: E04F19/02
Filed: 1993-05-06
Abstract: A fire-resistant wall structure is provided with a recessed corner guard,  for absorbing impact  forces, particularly at an external corner.  To compensate for the relative loss of fire-resistance capability, in the area in which the wall structure is recessed to receive the corner guard structure, surfaces within the recess are provided with a layer of intumescent paint which, when exposed to sufficiently elevated temperature,  expands to develop a thick,   cellular  foam  providing  a  highly  effective insulating layer.  The intumescent paint can be applied to surfaces of the recess itself,  and/or surfaces of the corner guard assembly installed in the recess.   In the latter case, the paint can be applied at the factory where the corner guard components are manufactured.  Significant benefits are realized in relation to prior practices of installing ceramic matting  in the wall  recess  at the construction site.
