US Patent:

50257935, Jun 25, 1991

Filed:

Sep 29, 1988

Appl. No.:

7/250989

Inventors:

Edward A. Richley - Mountain View CA
Christopher E. Russell - Mars PA

International Classification:

A61B 5022

US Classification:

128677

Abstract:

A system for blood pressure measurement ascertains blood pressure indirectly by the oscillometric method at the user's index finger. Finger measurement allows the system to be smaller and easier to use than systems using conventional upper arm measurement. By using the oscillometric technique, the system according to the invention needs no microphone and so avoids the problems associated with microphone positioning. The system employs a rigid finger cuff with an inflatable inner bladder. The system extracts pulse signals transmitted via air pressure while simultaneously providing accurate pressure control.

Abstract:

Systems, methods, and computer-readable media for operating a virtual environment are provided. The method can include receiving information associated with a thing in view of an augmented reality (AR) device. The thing can be a physical object or a virtual element, such as text on a screen or a web page. The method can further include identifying the object or thing based on the information, identifying virtual content associated with the object or thing, determining that the AR device is permitted to receive at least a portion of the virtual content, transmitting the virtual content to the AR device based on the determining, and causing the AR device to display the virtual content. The ability of a user to view the virtual content associated with the object or thing can further be limited by an authentication process or access level.
