摘要:
A stylus-aware computer system and method are provided for processing information obtained by moving a stylus over a tablet of the type that displays images as well as inputs stylus information. As a user moves the stylus with respect to the tablet, the tablet generates outputs describing the position of the stylus with respect to the tablet. A tablet driver converts this data into standardized packet objects recognized by the computer system and sends the packet objects to a stroke manager. The stroke manager converts the package objects to stroke objects which represent the trajectory of the stylus with respect to the tablet at times between two transitions such as placing the stylus on the tablet and lifting the stylus off the tablet. The stroke manager notifies an application of the stroke object through an event queue. The application may then issue stroke commands which dictate how the stroke is used. The stroke may, for example, be drawn on the tablet, erased from the tablet, removed from memory, etc.

A method and apparatus is described for producing a translucent image over a base image created on the display screen of a computer system by a selected first application program, and conducting image operations either on the base image created by the selected application program with reference to the translucent image produced, or conducting image operations on the translucent image with reference to the base image of the first application program. The first application program runs on a central processing unit (CPU) of a computer system to produce a base image, and another application program referred to as the overlay program is run to produce the translucent image such that portions of the base image which are overlapped by the overlay image are at least partially visible through the translucent image. There is also a mechanism for blending the first video data and the second video data to produce a blended image on the screen assembly.

摘要:
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. In addition a pen computer system includes a central processing unit (CPU), a screen assembly coupled to the CPU, a mechanism coupled to the screen assembly for displaying a base image on the screen assembly, and a mechanism coupled to the screen assembly for displaying an overlay image on the screen assembly such that portions of the base image which are overlapped by the overlay image are at least partially visible through the overlay image. The screen assembly includes a tablet mechanism coupled to the CPU which can receive input from a pen or stylus. The mechanism for displaying a base image includes a first computer implemented process running on the CPU which produces first video data and a video driver circuit coupled between the CPU and the screen assembly. The mechanism for displaying the overlay image includes a second computer implemented process running on the CPU to produce second video data, and a video driver circuit coupled between the CPU and the screen assembly. There is also a mechanism for blending the first video data and the second video data to produce a blended image on the screen assembly. This blending mechanism can include the second computer implemented process, or can comprise the video driver circuitry.

A virtual database system including multiple independent database servers is disclosed. The virtual database system uses a unified interface to query multiple independent databases, and the multiple independent database servers include appliances, general servers, etc. The system preferably includes a packet-based network, and a number of physically separated, independent database servers coupled to the network, where each of the database servers has a unique address and an independent database interface. Preferably, each database server includes an database created at least in part by the passive capture of data on the network, and each of which supports database queries including at least one of metadata and text via its respective interface. Queries are distributed concurrently to a number of appliances as virtual user queries.

An example embodiment includes a processor module, a pipe analyzer and a central processing unit. The processor module extracts a plurality of components from an input bit stream by extracting predetermined n-bits at a time from the input bit stream and analyzing the n-bits for components. The central processing unit has at least two pipelines for receiving the components derived from the input bit stream. The pipe analyzer is coupled between the processor module and the central processing unit for analyzing the components of the input bit stream and directing each of the components into a suitable pipeline of the central processing unit based on the analysis the pipe analyzer.
摘要:
The present invention permits virtually the entire functionality of a computer system to be made accessible over a network such as the Internet or an Intranet. More particularly, the present invention permits a computer system to be run as a “virtual machine” through a web page provided at a web site on the World Wide Web (WWW). The apparatus of the present invention includes a plurality of computers arranged in a wide area network (WAN) such as the Internet or an Intranet. At least one of the computers has at least one unique address designating a web site. A host computer system (which may or may not be one of the computers on the Internet) can be “posted” onto an “advertising” web page at the web site to permit other computers coupled to the Internet to interact directly with the host computer system. The computer “posted” on the web page is referred to as the “host” or “advertiser” computer, and computers accessing the host computer are referred to as “client” or “user” computers. Having the host computer posted on a web page creates a “virtual computer” that can be view and/or controlled by the client computers. Once the connection has been made between the host computer and one or more client computers, the web page is bypassed, i.e. the two or more computer systems communicate through the Internet without necessarily going through the web site supporting the “advertising” web page.

An apparatus for detecting intensity saturation of a light sensor includes a saturation detector for detecting and measuring an intensity saturation condition of at least one pixel of a light sensor, the intensity saturation condition of the pixel being at saturation upon receiving light with an intensity above a predetermined level, the saturation detector emitting a digital signal with a reserved bit combination indicating the intensity saturation condition of the pixel, and a processor receiving and processing the digital signal from the saturation detector and transmitting a control signal in response to the digital signal to compensate for the intensity saturation condition of the pixel.
