Abstract: This invention allows a video network camera to be mounted directly against a window or other transparent surface without any additional mounting hardware. The network camera can be mounted both inside and outside of a window without additional mounting hardware. A novel mounting apparatus in conjunction with an adjustable video sensor allows the user to quickly mount and make adjustments to the viewing angle of the network camera, thus reducing installation time and installation costs. In addition, the network camera can be mounted to walls, ceilings and other surfaces as necessary by using a second mounting assembly.

Abstract: The present invention relates to detecting, identifying, and circumventing data obstruction systems on a computer device including firewalls, filters, etc. One embodiment of the present invention relates to a video monitoring system control module method for identifying and circumventing active data obstruction systems to enable video monitoring data transmissions. The method includes transmitting a plurality of test data packets over communication ports corresponding to video monitoring system related communication protocols, so as to generate a receive thread key of blocked and transmitted test data packets. The receive thread key is correlated with data corresponding to known data obstruction systems in order to identify at least one data obstruction system. Video monitoring data is routed around the identified at least one known data obstruction system, thereby circumventing the known data obstruction systems.

Abstract: The present invention relates to systems and methods for notifying a user of a video monitoring system event while other video monitoring system related functions may be performed in the background of a multi-use computing environment. For example, a graphical pop-up, priority image, and/or notification sound may be transmitted to a user within a multi-use environment to alert the user that a particular video monitoring system related event has occurred. One embodiment of the present invention relates to a video monitoring system disposed within a multi-use computing and communication environment. The system includes a video input source, and a control module disposed within a multi-use computing environment. The control module includes a user notification system configured to continuously monitor the video data for local video monitoring related events and transmit a notification to a user of the multi-use computer system.

Abstract: A new method and apparatus for creating, positioning and manipulating a garbage matte which obscures everything outside of a three-dimensional physical set or blue stage. Effectively, the garbage matte is a "negative" of a blue stage. What is important is that the garbage matte is created either as a virtual enclosure around all virtual objects in the virtual environment, or simply as a background color of the graphics engine generating the garbage matte. In this way, the garbage matte provides extensions of blue screens which comprise the blue stage, extending all the way around and behind the television cameras. Consequently, a compositor will not include in a composited output image those physical set elements which are masked by the virtual garbage matte. The compositor will replace areas hidden by the garbage matte with image data supplied by the computer image generator which stores the virtual environment.

Abstract: A patient-interactive method and apparatus for measuring eye refraction includes a display for producing, alternately, two spaced-apart light spots, and an aperture device for passing light from one spot through an aperture in one position, to travel to the eye, and for passing light from the other spot through an aperture in a second position, to travel to the eye. If the patient sees a single spot, the eye is properly refracting, but if he/she sees two spots, the eye is not properly refracting. Apparatus is provided to allow the patient to adjust the spacing of the light spots, and thus the angle that light enters the eye, until the patient views a single light spot. The amount of adjustment of the spacing of light spots is measured to thereby provide a measure of diopter correction necessary to correct the refraction error.

Abstract: A method and apparatus for performing a lens calibration procedure which is executed for each camera and lens pair. The calibration procedure is performed to determine the camera and lens nodal point offset and field of view, plus image offset in both the horizontal and vertical directions as a function of lens zoom and focus settings. The method includes the step of providing apparatus which enables the semi-automatic and rapid entry of data points representing lens zoom and focus setting information, thereby eliminating a source of human error. The general method includes the steps of creating a real environment and an identical virtual environment which is a copy of the real environment. The image from the virtual environment is superimposed on a monitor displaying the real environment. The camera's zoom and focus rings are incremented through a plurality of values by discrete steps. For each value, the virtual environment's settings are manipulated until the real and virtual images are identical.
