Abstract: Method and disinfection system for disinfecting a closed space or surface including light fixtures fixedly positioned at predefined locations in a closed space. The disinfection system includes a UV emitter module positioned over a robotic system. The light fixtures and the UV emitter module emit ultraviolet C (UVC) light for disinfecting the closed space or a surface in the closed space. The disinfection system includes sensors for measuring the amount of UVC light delivered by the light sources and UV emitter module. The disinfection system includes a control system for determining a profile for the closed space or surface based on the amount of UVC light needed and corresponding time to disinfect. The control system communicatively connects to the sensors. The control system monitors the amount of UVC light and controls the operation of the light sources and UV emitter module to deliver the required amount of UVC light.

Abstract: A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

Abstract: A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinsonian tremor, and other forms of tremor. The stimulator can have electrodes that are placed circumferentially around the patient's wrist or arm. Specific nerves in the wrist or arm can be targeted by appropriate spacing of the electrodes. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. The stimulation pattern may alternate between the nerves. Improved stimulation algorithms can incorporate tremor feedback, external data, predictive adaptation, and long-term monitoring data.

Abstract: Systems, devices, and methods for stimulating peripheral nerves in the fingers or hand to treat tremor are described. For example, a wearable ring device for delivering electrical stimulation to sensory nerves in a patient's finger can include an annular ring having a plurality of electrodes and a detachable unit having a power source and a pulse generator.

Abstract: Disclosed herein are system and method embodiments to implement a scout pulse LiDAR. An embodiment operates by emitting a leading sequence of two or more discrete pulses with a constant timing offset and large intensity ratio. These leading pulses are each called a ‘scout pulse’ because they scout ahead of the primary pulse to detect high intensity targets, which would otherwise saturate the detector. In the simplest configuration, there are only two pulses, one primary pulse (lagging, high power/intensity) and one scout pulse (leading, low power/intensity). In more complex configurations, there may be any number of multiple scout pulses, each with a unique time delay and intensity. In any configuration, the signals are emitted in order of ascending intensity, with the lowest intensity signal in front (first), and the highest intensity signal in the back (last) within the pulse train.

Abstract: Lidar systems may use highly sensitive GmAPD detectors to track obstacles in the environment of an autonomous vehicle. Data sensed by a lidar GmAPD detector can be pre-conditioned to facilitate differentiating low intensity signals from background noise. By sampling raw avalanche counts accumulated by the detector as Bernoulli trials, binomial statistics can be leveraged to transform raw data to a probability distribution, and then to a normalized data set suitable for signal processing.
