    Abstract: The invention discloses a system for controlling the movement of a personal mobility vehicle including a processing unit that receives and processes a location data of one or more obstacles over a period of time, determines a change frequency of change of location of the obstacles during the period of time, and generates a movement state categorization of the obstacles categorizing them into either a dynamic obstacle or a static obstacle. The processing unit further determines a dynamic distance traveled by the dynamic obstacle during the period of time, the velocity of the dynamic obstacle, determines movement probability data that relates to the probability of movement of a static obstacle based on the change frequency of change of location, and, determines velocity prediction data of a dynamic obstacle based on the velocity of dynamic obstacles during various time intervals of the time period.

    Abstract: Eyewear including a support structure defining a region for receiving a head of a user. The support structure supports optical elements, electronic components, and a use detector. The use detector is coupled to the electronic components and is positioned to identify when the head of the user is within the region defined by the support structure. The electronic components monitor the use detector and transition from a first mode of operation to a second mode of operation when the use detector senses the head of the user in the region.

    Abstract: A system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, an infrared emitter, and an infrared camera. The infrared emitter and the infrared camera are connected to the frame or the temple to emit a pattern of infrared light. The system includes a processor coupled to the eyewear device, a memory accessible to the processor, and programming in the memory. Execution of the programming by the processor configures the system to perform functions, including functions to emit, via the infrared emitter, a pattern of infrared light on an eye of a user of the eyewear device; capture, via the camera, reflection variations in the pattern of infrared light on the eye of the user; and identify a user of the eyewear device based on the reflection variations of the emitted pattern of infrared light on the eye of the user.

    Abstract: A system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, a fingerprint sensor, and a sensing circuit. The fingerprint sensor includes an input surface to receive input of a finger skin surface. The sensing circuit is configured to track a pattern of fingerprint ridges of the finger skin surface on the input surface. Execution of programming by a processor configures the system to perform functions to track, via the sensing circuit, the pattern of fingerprint ridges of the finger skin surface on the input surface; generate a fingerprint image having the tracked pattern of fingerprint ridges; extract fingerprint features from the fingerprint image; and authorize the user to utilize the eyewear device based on the extracted fingerprint features.

    Abstract: A system 1 for controlling a powered personal mobility vehicle 8. The system includes an input module 2, a processing unit 4, and a motor controller 7. The input module 2 receives manual triggers 3 regarding the movement of the personal mobility vehicle 8. The processing unit 4 processes a location information 5 or a distance information 6 at a given point in time, and further, either generate an automatic trigger 19, and disable or curtail the functioning of the input module 2, or enable the functioning of the input module 2. The location information 5 is defined as a location of an obstacle co-located in an environment in which the personal mobility vehicle 8 is placed or being driven, and the distance information 6 is defined as the distance of the obstacle from the vehicle 8 at a given point in time. The motor controller 7 receives and processes manual triggers 3 or automatic triggers 19 and controls movement of the personal mobility vehicle 8.

Further, based on the change frequency of change of location, the processing unit determines the movement probability data that relates to the probability of movement of a static obstacle. And, based on the velocity of dynamic obstacles during various time intervals of the time period, the processing unit determines the velocity prediction data which relates to the prediction of the velocity of a dynamic obstacle.
