Medtronic, Inc.’s patent US 6221059 B1 deals with Flow-directed catheter system and method of use.
A flow-directed catheter includes a catheter body having a relatively rigid proximal body portion and a relatively flexible, supple distal body part. The distal body part will have a reduced diameter relative to the proximal body portion, at least in its distal tip. Radiopaque points given to the transition between the two parts of the body and the tip of the catheter. The radiopaque markers that best recessed entirely within the catheter body. Optionally, the distal body portion may have surface irregularities that enhance the ability of the distal body part to keeping the blood flowing. A flow-directed catheter system comprising the catheter in combination with a coaxial sheath to selectively strengthen at least proximal to distal body part. catheter can be used for a variety of diagnostic and / or therapeutic procedures.

The 3Com Corporation patent solves the following problem:

Many modem business to use two separate telecommunications networks for voice and data. The costs associated with installing and maintaining two network prompted some businesses to find ways to integrate voice and data infrastructure in a telecommunications network. As a result, the telecommunications industry has produced systems that integrate telephone and computer to the same network. In such systems, telephone and computer to share the same cabling infrastructure for the transmission of data and voice data on the computer.

Our analysis of this patent is as follows:

3Com Corporation’s patent US 6212195 B1 deals with Telecommunication apparatus and method for forwarding packets using separate collision domains.
A telecommunication apparatus and methods for providing packages of at least one of a first and second network described. A telephone set connects the first network to the second network. In some pictures, the phone set include two devices MAC. Each MAC device is in electrical communication with one of the two network through a communication path. In another picture, a packet switching device provides another channel of communication to the two networks. The phone is set before the package received from one network to another network, create packages from the local signal inputted telephone and put forward the package generated at least one of the network, and do the works ordered the package received and referred to the phone set. Packages addressed to the phone set or not to send.

The Telefonaktiebolget Lm Ericsson (Publ) patent solves the following problem:

Applicants' invention relates generally to radiocommunication systems that use digital control channels in a multiple access scheme and especially in cellular TDMA phone system with digital control channels.

Our analysis of this patent is as follows:

Telefonaktiebolget Lm Ericsson (Publ)’s patent US 6212176 B1 deals with Digital control channels having logical channels for multiple access radiocommunication.
A communication system information transmitted in consecutive time slots grouped into a plurality of superframes which are, in turn, are grouped into a plurality of hyperframes. A remote station that is assigned to one of the time slots in each of the superframes paging the remote station, each hyperframe including at least two superframes, and the information sent in due time space a superframe every hyperfame repeated in the assigned time slot in the other superframe (s) in each hyperframe. Each superframe may include a plurality of time slots used to send paging messages to remote stations, grouped into a plurality of consecutive frames paging, time and space aside station assigned included once in every paging frame. Also, each superframe may include time slots comprising a logical channel for broadcast control information and time slots comprising a logical paging channel. Information sent to the appointed place to guide the remote reading station to broadcast information to prevent, and the information may be encoded according to an error correction code and includes a plurality of pieces with polarities inverses of cyclic redundancy checks particle produced by encoding. Also, the broadcast control information can include special messages included in the respective time slots comprising a logical special message channel, the time slots of the special message channel may group successive frame SMS, and the SMS frames can be simultaneously the beginning of a beginning of a superframe.
