Systems and methods for transseptal delivery of therapeutic devices
A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD. |

Receiving information through a zero-knowledge data management network
The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and/or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly. |

Orthogonal time frequency space modulation techniques
Orthogonal Time Frequency Space (OTFS) is a novel modulation scheme with significant benefits for 5G systems. The fundamental theory behind OTFS is presented in this paper as well as its benefits. We start with a mathematical description of the doubly fading delay-Doppler channel and develop a modulation that is tailored to this channel. We model the time varying delay-Doppler channel in the time-frequency domain and derive a new domain (the OTFS domain) where we show that the channel is transformed to a time invariant one and all symbols see the same SNR. We explore aspects of the modulation like delay and Doppler resolution, and address design and implementation issues like multiplexing multiple users and evaluating complexity. Finally we present some performance results where we demonstrate the superiority of OTFS. |

H-bridge integrated laser driver
An H-bridge integrated laser driver optimizes power dissipation, impedance matching, low-swing and high-swing reliability for electro-absorption modulated laser (EML) and directly modulated laser diode (DML) applications. The laser driver includes a retimer for converting low-speed parallel data to a high-speed serial bit stream and to an inverted representation of the high-speed parallel bit stream, an M-bit PMOS DAC configured to receive a first buffered bit stream, an N-bit NMOS DAC configured to receive a second buffered bit stream substantially synchronized with the first buffered bit stream. A protective device is coupled between the M-bit DAC and the N-bit DAC. A first DC level-shifting predriver array is coupled between the retimer and the M-bit DAC to receive the high-speed parallel bit stream and the inverted high-speed parallel bit stream, and a second DC level-shifting predriver array is coupled between the retimer and the N-bit DAC to receive the high-speed parallel bit stream and the inverted high-speed parallel bit stream. An impedance matching module is coupled to an output of the protective device. The laser driver may be integrated on a CMOS communication chip. |

Coaxial connector
There is provided a coaxial connector that can suitably bias a movable insulator to the side of a socket and maintain matched impedance. The coaxial connector includes a movable insulator that is fitted in a central conductor so as to be slidable and is housed in an insulator housing so as to be movable in an axial direction; and a biasing rubber member that is interposed between a partition disposed in the recesses of the insulator housing and the movable insulator. When the biasing rubber member connects the socket to the plug, the movable insulator is pushed in by a pushing force from a socket, and elastic pillars are bent in an arc shape. |
