Abstract: Techniques for determining heart rate variability (HRV) and subject data polar images are described. The techniques include determining data of a subject over a period of time that includes time segments and generating HRV feature values from the HRV data. Each one of the time segments is associated with at least one of the HRV feature values. The techniques also include generating, based on the HRV feature values and the time segments, a polar representation of the HRV data and outputting the polar representation as an image. The techniques further include inputting subject data (e.g., demographic data and/or clinical data of a subject) and using them to generate a filled-in color coded image. The generated image can be used further in a deep learning model to predict a heart failure category and decide on time segments or regions within the image that contribute toward the decision.

Abstract: A system for performing analog multiply-and-accumulate (MAC) operations employs at least one cross coupling capacitor processing unit (C3PU). A system includes a wordline to which an analog input voltage is applied, a voltage supply line having a supply voltage (VDD), a bitline, a clock signal line, a current integrator op-amp connected to the bitline and to the clock signal line, and a C3PU connected to the wordline. The C3PU includes a CMOS transistor and a capacitive unit. The capacitive unit includes a cross coupling capacitor and a gate capacitor. The cross coupling capacitor is connected between the wordline and the gate terminal of the CMOS transistor. The gate capacitor is connected between the gate terminal and ground. The CMOS transistor is configured to conduct a current that is proportional to voltage applied to the gate terminal.

Abstract: A robotic catheter can include bi-stable concentric tubes and a torsional spring mechanism that can provide torque at the proximal extremity of one or more tubes. The robotic catheter can compensate for the energy that may be released by the tubes snapping from on stable-equilibrium position to another by using the energy stored in the torsional spring mechanism. The energy released by the tubes upon snapping from one stable-equilibrium position to the other can be compensated by the energy stored in the torsional spring at the base, thereby resulting in the first, energy-free, zero stiffness catheter system that (1) synchronizes with the motion of the heart and (2) naturally results in optimal, pseudo-constant contact force with the tissue.

Abstract: Embodiments of the present disclosure include systems and methods for enhancing the performance and efficiency of separation processes. The methods include flowing a fluid through a processing zone defined by an antiferromagnetic portion of a conduit and, as the fluid flows through the processing zone, exposing the fluid to a magnetic field produced by oscillating electromagnetic waves, wherein the direction of the magnetic field is generally counter to the direction in which the fluid is flowing. The systems include magnetic treatment units, separation systems, and the like.

Abstract: This invention relates to methods and systems for searching. It is particularly applicable to methods of searching which enable efficient identification of compatible portfolios. Embodiments of the invention propose methods of searching which address the huge search space issue associated with identifying compatible portfolios. In particular, embodiments of the invention start their search operations simultaneously from both sides by both trying to form valid portfolios from candidate products until a valid solution is found and trying to find conflicts from the defined compatibility rules until a conflict is found which leads to the conclusion that no valid solution exists. A conclusion from either process will stop the whole searching process which can significantly reduce blind and unnecessary searching in the whole search space. In embodiments of the invention, the two sides of the search process are also connected in a way which permits two-way communications between the processes to share information about invalid search branches during the execution of the search. The shared information is then used to direct the current and later stage of search execution. Such exchange of information can also significantly reduce the search space and create more efficient searching systems and methods, particularly by stopping search agents from carrying out invalid future searches in branches that another agent has already identified as invalid.
