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.

Abstract: Systems and methods for camera height detection include a time of flight (TOF) sensor included on a camera within a camera array that emits a signal in an array of points. 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 missile comprises a generally cylindrical body having a distal end and a proximal end; a nosecone having a pointed distal end and a proximal end, wherein the proximal ends of the body and nosecone are oriented toward each other; a forward angled section rotatably attached to the proximal end of the nosecone at its forward edge, the opposite end of the forward angled section having an angled edge perpendicular to the longitudinal axis except for the angle defined by the edge; a rear angled section rotatably attached to the proximal end of the body at its rear edge, the opposite end of the forward angled section having an angled edge matching the angled edge of the forward angled section, the angled edges of the forward angled section and the rear angled section being rotatably attached.

Abstract: In biometric ticketing, physical token-less ticketing system using biometrics, a person may be identified using a digital representation of a biometric. Ticketing information may be ascertained based on the identification. The ticketing information may be provided, actions may be performed using the ticketing information, and so on. In some implementations, a checkpoint device receives biometric data from a person. A digital representation of the biometric data is used to obtain an identifier from an identification system. The digital representation of the biometric data may not be included in the identifier. The identifier is used by to obtain ticketing information from a ticketing system. The person may be allowed or denied entry into a ticketed area based on the ticketing information.

Abstract: A system receives a digital representation of a biometric for a person, uses the digital representation of the biometric to determine and/or otherwise retrieve identity information associated with the person, and uses the identity information to perform one or more actions related to the person's presence in one or more areas. For example, the system may estimate a path for the person and signal an agent electronic device based on the path. In another example, the system may determine a presence of a person within the area and/or transmit information to an agent electronic device regarding the determined presence. In still another example, the system may receive a request to communicate with the person and forward the communication to the person using the identity information.

Abstract: A system for authorizing a mobile identity information controlled device includes a mobile identity information controlled device, an identity system device, and/or an enabling device. At least one digital representation of a biometric is received using a biometric reader device. Identity information is obtained from an identity system device using the at least one digital representation of the biometric. Operation of the mobile identity information controlled device is controlled using the identity information. In some examples, the operation may subsequently be deauthorized if the at least one digital representation of the biometric and/or the identity information is not reobtained.

Abstract: The present disclosure provides methods of determining one or more tissues and/or cell-types contributing to cell-free DNA (“cfDNA”) in a biological sample of a subject. In some embodiments, the present disclosure provides a method of identifying a disease or disorder in a subject as a function of one or more determined more tissues and/or cell-types contributing to cfDNA in a biological sample from the subject.

Abstract: A golf swing speed trainer for releasable attachment via a retainer to a shaft sleeve of a golf club shaft, including a head, a sleeve, and a weighting system. The trainer provides a highly customizable golf swing speed trainer that more accurately mimics the feel of a real club as a golfer works to increase their swing speed, without introducing any new bad habits. It allows a golfer to use their “gamer” shaft and grip during speed training, thereby increasing the user's familiarity with the trainer, which should result not only in increased swing speed but also improved consistency and accuracy.
