Patent CA-2237939-A1 (CA)
Inventor: MANN STEVE
IPC: G06F1/16
Filed: 1998-06-29
Abstract: A novel means and apparatus for personal documentary photography and videographyis described. In particular, a personal camera with viewfinder means and a personal video annotation system is introduced. The camera system integrates theprocess of making a personal handwritten diary or the like, with the capture of video, from an optimal point of vantage and camera angle. This gives rise to a new formof personal diary, as well as a new genre of documentary video. Video of a subject such as an official behind a counter may be captured by a customer or patron of an establishment, in such a manner that the official cannot readily determine whether or not video is being captured with the handwritten notes or annotations.

Title: Modem loop current detect system to detect an off-hook condition in an extension telephone
Inventor: PITSCH ROBERT ALAN
IPC: H04B10/2581
Filed: 1996-12-18
Abstract: A telephone line monitoring circuit uses an optoisolator (OPTO 2) to convert the telephone line current to a voltage which is applied to the input of an A/D converter (118). The A/D values are coarse values representing telephone line current. The A/D is sampled at a predetermined interval to identify changes introduced by the telephone company central office, and to take those changes into account when deciding if an extension telephone has gone off-hook. When a customer causes an extension telephone to go off-hook, the line current divides between the extension telephone and the IRD modem (100), and such change is detected.

Inventor: CROSSLAND CLIFFORD S
IPC: B01J35/02
Filed: 1996-12-06
Abstract: A contact structure, useful as a distillation structure, has a rigid frame made of two substantially vertical duplicate grids (22) spaced apart and held rigid by a plurality of substantially horizontal rigid members (20) and a plurality of substantially horizontal wire mesh tubes (10) mounted to the grids to form a plurality of fluid pathways among the tubes. For use as a catalytic distillation structure, which serves as both the distillation structure and the catalyst, at least a portion of the wire mesh tubes contain a particulate catalytic material (30). The catalyst within the tubes provides a reaction zone where catalytic reactions may occur and the wire mesh provides mass transfer surfaces to effect a fractional distillation. The spacing elements provide for a variation of the catalyst density and loading and structural integrity.
