Title: Method of and apparatus for touch-input computer and related display employing touch force location external to the display
Inventor: ROBERTS JERRY B
IPC: G06F3/041
Filed: 1993-03-10
Abstract: ABSTRACT      A method of and apparatus for determination of touch location on a display screen or the like or other surface embodying a force-sensing platform or surface supporting or otherwise externally contacting the display screen monitor apparatus, and responding to the forces created by the thrust of touching a point of the display screen, to sense and calculate the location of the touching point.  The underlying technique employs force-sensing means responsive to all six degrees of freedom of applied (touching) force and torque, achieving force location away from the plane of the sensors and in spite of tangential force components by calculating the point of least magnitude of the three-dimensional torque vector from among all points within the screen or surface, and outputting this point as an estimate of the intersection point of the screen or surface with the thrust line of the touching or other contact force.

Filed: 1993-05-12
Abstract: Abstract of the Disclosure A plastic identification card is produced by a method in which a picture from a camera (i.e. a video camera) is initially continually viewed on a monitor until the picture is acceptable. once  acceptable,  the  picture  is processed,  preferably  in  a computer, and  converted  into  digital  data  from analog  data without  subsequently  immediately  displaying  a  visible reproduction of the picture.  No immediate visible reproduction of the picture  is needed because the picture was acceptable before processing.  After processing the picture is recorded in a memory,  preferably  in  a  memory  of  the  computer.    Other identification information (i.e. demographic information, etc.) pertaining to the picture can be assimilated and recorded int he memory in the form of digital data.  From the memory, the picture in the form of digital data and other identification information or  alphanumeric  information  may  be  printed  directly  onto  a plastic base material with a thermal dye transfer printer.  The plastic base material may be covered with a transparent coating or laminate.  All digital data or information may be stored in a permanent  memory  of  a  computer,  to  allow  another  plastic identification card to be reproduced in the  future,  with or without modification of the digital data.
Patent CA-2099048-A1 (CA)
Inventor: HOLLOWAY THOMAS F
IPC: A45D40/06
Filed: 1993-06-23
Abstract: A cosmetic preparation dispenser is provided that has a resilient tab formed on the lower end of the innerbody that presses against the cam sleeve to provide a desirable swivel drag, and which tab is prevented from undesirable deformation that reduces the swivel torque by providing a relaxation zone in the cam sleeve where the tab can recall its original shape.   The relaxation zone is preferably a thin walled section of the cam sleeve that is formed by the combination of a flat outer wall  and a circular inner wall, which thin walled section is deformable by pressure from the tab when the tab is seated against the thin walled section.  The tab presses against the cam sleeve which causes the cam sleeve to move up a bevelled shoulder to enhance swivel drag between the cam sleeve and a retaining lip on the innerbody.   The bevelled shoulder also engages the cam sleeve when force is applied to the elevator.
