Abstract:
A system for establishing wireless connection between a peripheral device and an intelligent device in a multi-computers environment having a plurality of intelligent devices, is disclosed. The system is in part included within the peripheral device which is preferably a mouse device and also is included within the intelligent device which is preferably a computer system. Specific routines of the system allow a user to work with any of the intelligent devices using only the one mouse device.
Abstract:
Security system for preventing a main computer device owned by an authorized user from beng used by unauthrorized people comprising an extractable security piece (10) which can be removed from the computer device by the authorized user, such an extractable security pice containing at least an extractable main private key (20) and a main PC public key (22), a PC security area (12) which is a non-extractable part of the computer device, such a PC security area containing at least a PC private key (34) and an extractable main public key (32) consitituting with the keys of the extractable security piece a Public Key Infrastructure (PKI), and processing means (14, 16) in each of the extractable security piece and the PC security area for carrying out a mutual authentication of the extractable security piece and the PC security area after the eytractable security piece, which had been previously removed, has been put back at its right location thereby enabling the authorized user to access data stored in the computer device.
Abstract:
PROBLEM TO BE SOLVED: To provide a security system based on a public key infrastructure PKI preventing an unauthorized person from using a main computer unit belonging to an authorized user. SOLUTION: The public key infrastructure PKI is constructed of a removable security part including a main secret key and a main PC public key, and a PC security area including an extractable PC secret key and an extractable main public key. After the removable security part, which is already removed, is inserted into a remote computer unit, mutual authentication between the removable security part and the PC security area is carried out, and a user authorized in this way can access data stored in the computer unit.

Abstract:
PROBLEM TO BE SOLVED: To provide a hardware device which better responds to the necessity of each program, can use a simple instruction when necessary and processes an instruction set that can use more complicated instruction than adaptable to a basic instruction sequence used most frequently. SOLUTION: This device is a hardware device which processes in parallel a decided instruction out of a programmable instruction set that shares a format and has an instruction code field defining an execution step of an instruction corresponding to execution of a microinstruction. In this case, judgment blocks (12 to 20) each of which is associated with a specific instruction of a programmable instruction set and only one of which is selected by a decision instruction in order to define a specific microinstruction to be processed for executing a decided instruction, activation blocks (22 to 30) each of which is associated with the judgment blocks, executes the specific microinstruction and only one of which associated with the selected judgment block is activated and executes the specific microinstruction, and a microinstruction selection block 46 which is connected to each of the activation blocks and selects the specific microinstruction to be executed.

Abstract:
System for transferring a data file from a web server to a user workstation through a network and reciprocally, the user workstation including a hard disk ( 205 ) for storing the data file being transferred over a SCSI bus ( 208 ). The user workstation includes a dual-port memory ( 304 ) for storing temporarily the data file, a network logic unit ( 302 ) interconnected between the network and the input port of the dual-port memory for receiving the data file from the network and transmitting it to the dual-port memory, and a SCSI logic unit ( 303 ) interconnected between the output port of the dual-port memory and the SCSI bus for transferring the data file from the dual-port memory to the hard disk over the SCSI bus and reciprocally.
Abstract:
A method and system for dynamically inverting an A symmetric Digital Subscriber Line (ADSL) system. The ADSL system includes a central exchange equipment (CE) connected to a service provider network and a user equipment (UE) connected to a user workstation. The CE and UE are interconnected by a PSTN link. The CE includes an ADSL transceiver and a splitter coupled between the CE transceiver and the PSTN link. The splitter includes a low-pass filter for separating low frequency voice signals from high frequency ADSL signals transmitted from the UE. In accordance with the method of the invention, an invert request message encoded as a tone sequence is generated by the UE and transmitted to the CE over the PSTN link. The tone-encoded invert request is received through the CE splitter low-pass filter and is decoded utilizing a tone decoder communicatively coupled between the CE splitter low-pass filter and the CE transceiver.
Abstract:
Data transmission system for transmitting packets of data from a source workstation ( 10 ) to a destination workstation ( 18 ) wherein the packets of data are transmitted over at least an IP network ( 14 ) between an ingress node ( 16 ) connected to the source workstation and an egress node ( 20 ) connected to the destination workstation, wherein each router within the intermediary nodes along the data path from the ingress node to the egress node determines the best route in a routing table defined by the contents of a field contained in each packet of data being received. For this, the router of the ingress node comprises a configuration table which defines the contents of the TOS field in function of information associated with the 4/5 level protocol such as TCP or UDP.
Abstract:
The wireless communication system has two USB hubs (10,12), connected by wireless communication, with one connected to the host computer (16) and the other connected to a number of bidirectional ports (20). Each hub has a radio adapter (28,30) with an antenna (32,34) and a number of USB connectors.
Abstract:
