摘要:
An image guided autonomous needle insertion device including a delivery system, a path planner, an image processor, and a human machine interface. The system also includes an ultrasound probe in communication with a frame grabber, a percutaneous insertion device, and at least a first actuator for moving the percutaneous insertion device within a first degree of freedom and a second actuator for moving the percutaneous insertion device within a second degree of freedom. Each actuator has a corresponding position sensor for detecting its location with respect to a target. The system can further comprise an image processor for removing noise and segmenting the ultrasound images to highlight potential targets.
摘要:
A method of securely executing practically unbounded input stream of symbols, by non-interactive, multi-party computation, according to which the input stream is distributed among a plurality of parties, which do not communicate among themselves throughout execution, by a dealer with a secret initial state. The dealer distributes shares of the secret state between the parties. The input stream is executed by a finite-state automaton which may be an accumulating automaton with accumulating nodes or an automaton that is defined by a series of cascaded equations. During any execution stage, the input stream and the current state of the original automaton are concealed from any coalition of participants being smaller than a given threshold. Upon receiving a signal from the dealer, the parties terminate the execution and submit their internal state to the dealer, which computes the current state that defines the computation result.
摘要:
The present invention relates to methods for fabrication or modification of polymer membranes for water treatment utilizing ink-jet printing. The methods of the invention provide substantial advantages over the current state of the art including, inter alia, accurately delivering precise amounts of liquids to surfaces; quickly changing coating parameters; quickly controlling and changing coating compositions; and tailor-making membranes according to customer needs. The membranes fabricated or modified according to these methods have improved antifouling properties.

摘要:
A spectroscopic method using either tunable or preset non-tunable thin-layered devices or a combination of both to modulate compressed-sensing-compliant, spectral modulations and to use intensity measurements of each respective spectral modulation to numerically reconstruct an estimated spectral distribution of the spectral signal such that the estimated spectral distribution is characterized by a totality of spectral bands exceeding the number of spectral modulations by about one half an order-of-magnitude or more.
