  • Patent number: 9432328
    Abstract: The object of the invention is a method to receive and send electronic mail from a transmitting user to a recipient, generating proof of the operation transactions to submit the transmitting user a certificate as a trusted third party. To that end, it features the steps of reception in a mail server of a copy of the first electronic message sent by the transmitting user to the recipient, the later delivery of a copy of the first electronic message to the recipient together with a particular indication, so that the recipient receives a second electronic message copy of the first electronic message from the mail server, which comprises that particular indication. Finally, the data processing unit creates an electronic document with the transactional data of the delivered copy and signs it digitally creating a certificate that is sent to the initial user.

  • Patent number: 9292302
    Abstract: Provided is a method for temporarily skipping a secure boot function. A computer is configured so that a secure boot function is set as enabled by default. Depression of a power button of the computer in a power-off state generates a startup signal. At the time of startup from S4/S5 state, a switch is turned ON and PP bit indicating physical presence is set at a register. Depression of a specific key on a keyboard causes DE bit to be set at a register. When PP bit and DE bit are found, UEFI firmware stored in a firmware ROM temporarily skips integrity validation of a boot program only for boot this time.

  • Patent number: 8879700
    Abstract: A communication apparatus repeatedly outputs a first multi-carrier signal SS during predetermined periods T1, T2, T3, . . . , and outputs a second multi-carrier signal RS whose phase vector is different from that of the first multi-carrier signal SS, at a predetermined timing based on the first multi-carrier signal SS. The communication apparatus further detects the second multi-carrier signal RS output from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.

  • Patent number: 7924990
    Abstract: A communication apparatus repeatedly outputs a first multi-carrier signal SS during predetermined periods T1, T2, T3, . . . , and outputs a second multi-carrier signal RS whose phase vector is different from that of the first multi-carrier signal SS, at a predetermined timing based on the first multi-carrier signal SS. The communication apparatus further detects the second multi-carrier signal RS output from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.

  • Patent number: 7876775
    Abstract: In a particular embodiment, the disclosure is directed to a method of making a digital subscriber line (DSL) connection to a remote network. The method includes detecting the presence of a powered-on network capable device that is connected to a DSL modem; establishing a network connection over a DSL line to the remote network after detecting the presence of the powered on network capable device; terminating the network connection over the DSL line after detecting an absence of network capable devices connected to the DSL modem; and releasing network resources supported by the remote network after the network connection is terminated.

  • Patent number: 7848495
    Abstract: A voice communication apparatus is interposed between a telephone set and a public switched telephone network (PSTN) or a broadband network which can provide a frequency bandwidth broader than a frequency bandwidth of the public switched telephone network. The apparatus selects one of the PSTN and the broadband network, from which a voice signal is input. The apparatus takes account of the selected network, frequency characteristics of the selected network and of the telephone set, and appropriately adjusts frequency characteristics of a voice signal transmitted between the telephone set and the selected network by means of transmitter and receiver band-pass filter units. As a result, both the telephone set and the counterpart communication terminal can receive a voice signal of better transmission quality.

  • Patent number: 7804888
    Abstract: A back-up solution is presented for a DSL modem that guarantees essentially uninterrupted data connections in the event of a failure in the DSL connection. When a DSL data connection fails, e.g., due to changes of the local loop characteristics in the high frequency band, a voice-band modem is used in conjunction with an amplitude modulator/demodulator to keep the data connection uninterrupted by shifting the voice-band modem signal up to DSL frequencies, transmitting the data at this higher frequency over the local loop between the subscriber and a DSLAM, and then shifting the voice-band modem signal back to a “normal” frequency and demodulating this signal using the voice-band modem before it enters the data network. Since the frequency band used is at a frequency higher than that of voice communications, the subscriber can continue to use the local loop to conduct voice communications or any other communications that require use of the voice band frequencies, such as facsimile and V.

  • Patent number: 7746905
    Abstract: In conjunction with a data communication network (53) carrying multiple telephony signals and allowing for connection of telephone sets (17), a system and method in which two external feeders (55a, 55b) connect to the data network (53) at two distinct points via two distinct devices. The data network can be based on dedicated wiring or can use existing in premises medium such as telephone, powerlines or CATV wiring. In the latter case, the wiring can still carry the original service for which it was installed. The external telephone connections can be based on the traditional PSTN, CATV network, cellular telephone network or any other telephone service provider network, using specific adapter for any medium used. In the case of connection to a POTS telephone signal, VoIP gateway (or any other converter) is required.
