The access sheath shaft can comprise a first delivery lumen extending from a proximal end of the access sheath shaft to a side opening on a distal portion of the access sheath shaft, the first delivery lumen having a width configured to slidably receive a distal portion of a medical device disposed around a guidewire. The access sheath shaft can comprise a tapered distal end portion disposed distally of the side opening. A recess can extend along a longitudinal dimension of the tapered distal end portion from a proximal end to a distal end of the tapered distal end portion. The recess can be in fluid communication with the first delivery lumen and have a width smaller than the diameter of the first delivery lumen.

Abstract: Circuit and method for inter-symbol and intra-symbol voltage method are disclosed. Herein, a transceiver circuit is configured to determine a voltage target(s) for generating a modulated voltage(s) to amplify a radio frequency (RF) signal modulated in multiple symbols. Specifically, the transceiver circuit will generate multiple voltage targets for any of the symbols to thereby enable intra-symbol voltage modulation when the respective symbol is modulated to carry a selected type of information or generate a single voltage target for any of the symbols to thereby enable inter-symbol voltage modulation when the respective symbol lacks the selected type of information. By dynamically performing inter-symbol and intra-symbol voltage modulation based on the type of information carried in a symbol(s), the modulated voltage can be timely adapted to closely track a time-variant power envelope of the RF signal to thereby avoid potential distortion and protect critical information in the RF signal.

Abstract: Certain aspects of the present disclosure provide techniques for converting a bridged token on a blockchain to a native token on the blockchain. An example method generally includes pausing a token bridge between a first blockchain and a second blockchain. Minting privileges on the second blockchain are adjusted such that a designated user is granted privileges to control token minting on the second blockchain and no other users are allowed to control token minting on the second blockchain. It is validated that a quantity of a bridged token has remained unchanged since a freeze time at which the token bridge was paused. Based on validating that the quantity of the bridged token has remained unchanged since the freeze time, the bridged token is converted to a native token existing on the second blockchain.

Abstract: A digital communication method over an optical channel. Bob modulates a coherent optical signal with a random envelope phase ?r, known to him and not to Alice, and transmits the modulated coherent optical signal (envelope) over the optical channel to Alice. Alice further modulates the envelope with a key phase ?k, based on a secret key and a selected modulation scheme, to create a cipher envelope, and sends the cipher envelope towards Bob along the optical channel. Bob then demodulates a received version of the cipher envelope by removing the random envelope phase ?r (known to Bob) and then measures the phase of the resulting demodulated coherent optical signal with the coherent detector to extract, to within a certain margin of error, the key phase ?k, from which Alice's secret key can be decoded. Bob then uses the secret key for encrypting messages sent to Alice over any digital network.
