  • Patent number: 12281985
    Abstract: Described herein are methods for imaging a fluorescent bioassay (including a substrate, such as dispersed cellular sample, exposed to one or more exogenous fluorophore and/or fluorescent probe that accumulate in a structure of interest). The bioassay can be excited with Type-C ultraviolet (UVC) light produced by one or more light emitting diode (LED). The UVC can have a center wavelength that causes emission by the fluorescent bioassay. A digital optical device can collect a signal emitted from the fluorescent bioassay in response to the excitation. The methods relate in particular to Microscopy with Ultraviolet Surface Excitation (MUSE) imaging.

  • Patent number: 12274882
    Abstract: One aspect of the present disclosure relates to a system that can prevent unintended signal components (noise) in an electric waveform that can be used for at least one of neural stimulation, block, and/or sensing. The system can include a signal generator to generate a waveform that includes an intended electric waveform and unintended noise. The system can also include a signal transformer device (e.g., a very long wire) comprising a first coil and a second coil. The first coil can be coupled to the signal generator to receive the waveform and remove the unintended noise from the electric waveform. The second coil can pass the electric waveform to an electrode. The second coil can be coupled to a capacitor that can prevent the waveform from developing noise at an electrode/electrolyte interface between an electrode and a nerve.

  • Patent number: 12253587
    Abstract: The present disclosure provides transmit/receive (T/R) systems for NMR or MRI systems. In one configuration, the systems and methods provided herein may use passively-shielded coils that are compatible with low-field operational environment to replace conventional T/R systems and spatial gradient systems. In some configurations, a low-field imaging T/R system is provided that is designed for nuclear magnetic stimulation and local flux sensitivity, while automatically rejecting incident radiant electromagnetic noise. The design advantageously leverages low required frequencies to distribute the pulse synthesis task, yielding a smaller system with easier maintenance and lower cost. The system may include distributed coil nodes that include a primary radiofrequency (RF) coil configured to transmit and receive RF signals and a secondary coil configured to passively shield the primary RF coil.

  • Patent number: 12253469
    Abstract: Described herein are systems and methods for improving light-sheet microscopy with cost-effective and simplified components. Such cost-effective and simplified components can be implemented in a light focusing system, a light generation system, and/or in imaging system. The light focusing system can be improved by attaching a voice coil motor to a focusing lens to increase the imagable field of view. The light generation system can be improved with a multimode laser diode to increase the uniformity of the beam profile and to increase the usable optical power. The imaging system can be improved by using a fluid chamber with positive cylindrical optical window for minimizing spherical aberrations.

  • Patent number: 12246174
    Abstract: Chronic pain management can be achieved by electrically anesthetizing a peripheral nerve with on-demand electrical nerve block (OD-ENB). OD-ENB can be provided by an implantable capsule. Externally, at least a portion of the capsule can be constructed of a conductive membrane and the rest of the capsule comprises a biocompatible material. A blocking electrode contact, a return electrode contact, and a powering/communication component can be within the capsule. The blocking electrode contact can deliver a direct current (DC) through a portion of the conductive membrane to block conduction in the neural tissue to provide the OD-ENB. The return electrode contact can receive a return current from the neural tissue through another portion of the conductive membrane. The powering/communication component can communicate with one or more external components located external to the patient's body to receive a power signal. Notably the capsule has no internal battery.
