Abstract: Systems and methods are provided for managing, optimizing subject information, recommending ophthalmologic assessments, and performing diagnostic assessments. The system includes a computing device having an image-capturing device and a display. The system includes a computer application that is executable on the computing device and operable to receive information regarding a subject, recommend ophthalmologic tests based on the information received, and perform ophthalmologic assessments on a subject. Performance of the ophthalmologic assessments causes the application to generate information regarding the ophthalmologic health of the subject, analyze the information generated, and present results of the analysis on the display.

Abstract: Improved approaches for providing on-line appointments over a network are disclosed. The network is, for example, a global computer network such as the Internet. According to one aspect, users are able to schedule appointments over the network by on-line means. The users are typically individuals or service providers. Service providers are often those businesses that offer appointments to schedule their services.

Abstract: Improved approaches to providing on-line appointments over a network are disclosed. The network is, for example, a global computer network such as the Internet. One of the improved approaches provides various notifications to requestors pertaining to appointments with individuals or businesses (e.g., service providers). In one implementation, the notifications can be provided by electronic mail. Another of the improved approaches allows notifications pertaining to requested appointments to be provided to service providers that have not previously registered to receive on-line appointments.

Abstract: A method and apparatus in an electronically controlled system such as a portable computer are provided for minimizing effects of noise picked up by an input device such as a touch-sensitive capacitive coupling input pad where a conductive stylus may be used on the pad to control the cursor movement on a display device. The present invention removes the cursor jitters on the display device that is associated with the input device and provides for quick cursor responses corresponding to quick motion input by the conductive stylus on the input pad.

Abstract: A method and apparatus for blending first and second images stored in respective first and second VRAM buffers for production of a combined image on a computer display screen. The method includes storing a first image to be blended in a first VRAM buffer and storing a second image to be blended in a second VRAM buffer. The blending mechanism includes the process of loading the respective VRAM buffers with component 4 bit contributions of information representing first and second gray levels or color tones pixelwise representative of corresponding pixel portions of the respective first and second images to be combined. The output of the VRAM buffers combines these contributions of the respective first and second images to produce an address to a look-up table which produces at that particular address location a blended gray level or color tone representative of a blending of the two gray levels or color tones.

Abstract: A method and apparatus for providing a translucent overlay image over a base image on the screen of a computer system. The method includes the steps of running an application program on a central processing unit (CPU) of a pen computer system to produce a base image in a screen coupled to the CPU; and running an overlay program on the CPU to produce an overlay image on the screen such that portions of the base image which are overlapped by the overlay image are at least partially visible through the overlay image. The overlay program is a computer implemented process comprising the steps of displaying an overlay image on the screen, intercepting screen inputs which contact the overlay image, processing the intercepted screen inputs in the CPU, and updating the application program based on the processed screen inputs.
