Our analysis of this patent is as follows:

Rossides; Michael T’s patent US 6131085 A deals with Answer collection and retrieval system governed by a pay-off meter.
invention is a set of processes for improving the interface with a self-organized database. This kind of database stores the two questions and answers. The improved interface could process a user found a (first) question the database into a new (second) questions and write the second question as "more specific" than the first . When a user presses an "enter more specific question" command, the system enables the user to enter a question and then stores the questions and called it more specific than the first, and link the two questions in the database. Then, when any user to the first question, the system enables him to "go" involved, more specific questions by entering into a "go to more specific questions" command. Additionally, when a user found a question, the system can get a list of all the more specific questions related to the question. system also enables a user to find a first question and then enter a new (second) questions and write it as a first means. The system will involve two questions as synonyms in the database. Moreover, when any user found a question, the system can get a list of all those involved "similar" questions and help the user to "go to" a relative sense question by selecting it.

The Pitney Bowes Inc. patent solves the following problem:

The subject invention relates to a method and apparatus for storing information and controlling access to information. Particularly, it relates to a method and apparatus for safely storing information on a sensitive nature, such as medical histories, and access control information to limit access to people or organizations that authorized access.

Our analysis of this patent is as follows:

Pitney Bowes Inc.’s patent US 6131090 A deals with Method and system for providing controlled access to information stored on a portable recording medium.
A method and system to provide controlled access to information stored on a smartcard. The system includes a data processing center maintained by a trusted third party for storing a database of authorizations for various service providers with access to information about individuals, and for to respond to the request by the service providers for access from the terminals to communicate with the data processing center and smartcards hide information to people. The information stored in the smartcard in encrypted form and the data processing center provides an access code, which includes a key for decrypting the information, only the service providers who are authorized to access the information. The service provider then sends the access code on the smartcard which verifies the access code and decrypts and outputs the requested information. smartcard then calculate a new key as a function of the information unique to each session access and use the new key to encrypt the information, and then erases the new key. The data processing center to calculate the new keys as the data processing center will provide an access code including the new key for the next request for access.

The Vantis Corporation patent solves the following problem:

The invention is generally directed to the integrated circuit, more specifically the on-chip memory provided for run-time use in automatic Logic Devices (PLD), and even more specifically to a subclass of PLD's known field automatic Gate Arrays (FPGA).

Our analysis of this patent is as follows:

Vantis Corporation’s patent US 6127843 A deals with Dual port SRAM memory for run time use in FPGA integrated circuits.
A field-automatic gate array device (FPGA) with plural rows and columns of justice function units (VGB) further includes plural columns of embedded memory blocks, each memory block included a corresponding row of logic function units. Each equity unit function (VGB) organized the processing of a data nibble. Each embedded memory block the multi-reported and organized storage addressable data nibbles. Linking resources to efficiently transfer data nibbles between the logic function unit (VGB) and corresponding blocks of memory. Further linking resources (SVIC) provided for supplying address and control signals to each class in mind. An image of each memory block has at least one read-only port and at least one read / write port individually addressable and individually switchable to high impedance output through tri-state .
