Abstract: The present invention is an apparatus and method of providing notification of a content change of a web page. The method includes the steps of transmitting a request from a first electronic system to a second electronic system for a quotient value indicative of the content change, transmitting the quotient value from the second electronic system to the first electronic system, comparing the quotient value to a predetermined value to determine whether a threshold is triggered, and notifying the first electronic system of the content change if the threshold is triggered.

Abstract: Still image capture under computer control. The computer is instructed to capture the still image capture at an occurrence of a trigger and, subsequently in time, captures the still image. In embodiments, the instructions can be made through a graphical user interface (GUI) displayed on a monitor or a keyboard coupled to the computer. The instruction can start a timed count until the still image is captured. In embodiments the trigger can be an external event, such as sound or motion sensed by appropriate transducers. In yet other embodiments, the computer issues a notification of an occurrence of a capture or a warning of an impending capture.
