Abstract: Devices, systems, and methods of the present disclosure can overcome physical constraints associated with catheter introduction to facilitate the use of a catheter with a large distal portion as part of a medical procedure benefitting from such a large distal portion, such as, for example, cardiac ablation. More specifically, devices, systems, and methods of the present disclosure can compress an expandable tip of a catheter from an expanded state to a compressed state along a tapered surface of an insertion sleeve for advancement of the expandable tip into vasculature of a patient. The tapered surface of the insertion sleeve can, for example, apply compressive forces at an angle against the advancing expandable tip. As compared to other approaches to the application of compressive force to an expandable tip, compressing the expandable tip using an angled force can reduce the likelihood of unintended deformation of the expandable tip.

Abstract: Systems and methods are described for improving audio quality. Sensor data is received from an accelerometer of a camera. Based on measurements captured by the sensor data, a position of a lens of the camera and a current field of view (FOV) of the camera is determined. Audio beamforming is performed based on the current FOV of the camera by selecting a subset of microphones disposed on the camera to record audio based on the position of the lens and the current FOV of the camera; and activating the subset of microphones disposed on the camera, where microphones outside the selected subset of microphones are excluded from activation so that audio originating outside of the current FOV is removed.

The system executes the machine learning model to predict a score for each user. The system ranks the users based on the scores. The system ranks the users based on the scores and communicates with a subset of users selected based on the ranking.

After receiving a reflected signal at the TOF sensor, where the reflected signal is a bounce back of the emitted signal from at least a subset of the array of points, a distance to each respective point in the array is determined based on a time it takes to receive the reflected signal from each respective point in the array. A depth map is generated from each respective point, where the depth map provides distance measurements to objects within an environment of the camera. A vertical position of the camera is determined based on the depth map.

Abstract: A golf training device can include a resilient planar portion configured to present a face at a pre-set angle toward an oncoming golf club face. The device can include stand configured to hold the resilient planar portion above the ground and fix the pre-set angle for contact by the golf club face. The stand can have an offset base configured to avoid contact by the golf club. The planar portion can be configured to receive contact by the golf club face and promptly and resiliently return to the pre-set angle, thereby facilitating repeated practice swings of the golf club face. The planar portion can be configured to emit a first sound when the golf club face strikes the planar portion in an aligned manner, and to emit a second sound when the golf club face strikes the planar portion in a non-aligned manner.
