  • Patent number: 10110945
    Abstract: Maintaining synchronization of encryption processes at devices during transmission of encrypted data over a communication link is provided. Cipher link maintenance characters are sent from a source device to a sink device. A local cipher link maintenance character generated at the sink device for decrypting the encrypted data can be adjusted according to the cipher link maintenance character. After authentication, cipher link maintenance characters corresponding to units (e.g., frames) of the encrypted data are sent along with the units of the encrypted data. When a transmission error occurs during transmission of the encrypted data, cipher link maintenance characters can be used to correct the error in a local cipher link maintenance character generated at the sink device. Hence, even if the transmission error occurs in the communication link, the sink device can resolve the transmission error and maintain the synchronization of encryption processes at the source and sink devices.

  • Patent number: 10039901
    Abstract: Apparatus and methods for deactivating renal nerves extending along a renal artery of a mammalian subject to treat hypertension and related conditions. An ultrasonic transducer (30) is inserted into the renal artery (10) as, for example, by advancing the distal end of a catheter (18) bearing the transducer into the renal artery. The ultrasonic transducer emits unfocused ultrasound so as to heat tissues throughout a relatively large impact volume (11) as, for example, at least about 0.5 cm3 encompassing the renal artery to a temperature sufficient to inactivate nerve conduction but insufficient to cause rapid ablation or necrosis of the tissues. The treatment can be performed without locating or focusing on individual renal nerves.
