    Abstract: Embodiments herein relate to reflective optical medical sensor devices. In an embodiment, a reflective optical medical sensor device including a central optical detector and a plurality of light emitter units disposed around the central optical detector is provided. A plurality of peripheral optical detectors can be disposed to the outside of the plurality of light emitter units. Each of the plurality of peripheral optical detectors can form a channel pair with one of the plurality of light emitter units. The reflective optical medical sensor device can also include a controller in electrical communication with the central optical detector, the light emitter units, and the peripheral optical detectors. The controller can be configured to measure performance of channel pairs; select a particular channel pair; and measure a physiological parameter using the selected channel pair. Other embodiments are also included herein.

    Abstract: The present disclosure includes devices, systems, and methods for reducing signal noise in endoscopic rotational imaging. Many embodiments include an elongate member that includes an impedance matching network disposed between a proximal imaging core and a distal imaging core. In many such embodiments, the elongate member may connect a controller at the proximal end and include a rotational transducer at the distal end. In various embodiments, the proximal and distal imaging cores may include a plurality of insulated conductors disposed within a shield (e.g., a shielded twisted pair (STP)). In various such embodiments, the insulated conductors may be utilized to communicate differential signals between the controller and the rotational imaging transducer. In some embodiments, the insulated conductors in the proximal imaging core may have a larger diameter than the insulated conductors in the distal imaging core.

    Abstract: Systems, techniques, and devices are disclosed and may include a first sensor configured to generate a first data stream, a second sensor configured to generate a second data stream, and at least one processor and at least one non-transitory computer readable medium storing data stream management instructions. When executed by the at least one processor, the instructions causes the at least processor to receive the first data stream and the second data stream, spread the first data stream using a first code to generate a first coded data stream, spread the second data stream using a second code to generate a second coded data stream, combine the first coded data stream and the second coded data stream to generate a combined data stream, modulate the combined data stream to generate a modulated data stream, and transmit the modulated data stream via a single channel.

    Abstract: Embodiments herein relate to systems and methods for rapidly calibrating optical medical sensors. In an embodiment, a method can include placing a reflective optical medical sensor device on or in a patient. The reflective optical medical sensor device can include one or more optical emitters; one or more optical detectors; and a measurement circuit having one or more transimpedance amplifiers (TIA). The method can include setting the TIA to a fixed gain value and then turning on the optical emitter associated with each spatially unique measurement vector and receiving reflected light with the associated optical detector for each spatially unique measurement vector at the same fixed gain value. The method can include assessing the signal-to-noise (SNR) for each spatially unique measurement vector and selecting the spatially unique measurement vector having the highest SNR. Other embodiments are also included herein.
