Abstract: RF co-designed bandpass filters/isolators (BPFIs) are based on series-cascaded non-reciprocal resonant stages, microwave resonators and multi-resonant cells. The non-reciprocal stages are shaped by an in-parallel cascaded transistor-based path and a transmission line (TL) that result in a zero-phase resonance in the forward direction and high isolation in the reversed one. This includes coupling routing diagrams (CRDs) of BPFs that result in low- and high-order transfer functions with and without transmission zeros in their forward direction and high levels of isolation in the reverse one. BPFIs provide alternative-type of filtering responses (e.g., flat-passband, quasi-elliptic) with and without gain in the forward direction and high levels of isolation in the reversed one. BPFIs include five planar microstrip/lumped element (LE) prototypes using hybrid combinations of non-reciprocal resonant stages, microwave resonators and multi-resonant cells.

Abstract: Various embodiments of the disclosed technology present a structural foundation for volumetric flow reconstructions for expiratory modeling enabled through multi-modal imaging for pulmonology. In some embodiments, this integrated multi-modal system includes infrared (IR) imaging, thermal imaging of carbon dioxide (CO2), depth imaging (D), and visible spectrum imaging. These multiple image modalities can be integrated into flow models of exhale behaviors enable the creation of three-dimensional volume reconstructions based on visualized CO2 distributions over time, formulating a four-dimensional exhale model which can be used to estimate various pulmonological traits (e.g., breathing rate, flow rate, exhale velocity, nose/mouth distribution, tidal volume estimation, and CO2 density distributions).

Abstract: The present disclosure provides techniques for estimating network states using asynchronous measurements by leveraging network inertia. For example, a device configured in accordance with the techniques of the present disclosure may receive electrical parameter values corresponding to at least one first location within a power network and determine, based on the electrical parameter values and a previous estimated state of the power network, an estimated value of unknown electrical parameters that correspond to a second location within the power network. The device may further cause at least one device within the power network to modify operation based on the estimated value of the unknown electrical parameters. The leveraging of network inertia may obviate the need for probabilistic models or pseudo-measurements.
