Abstract: A wrist-wearable electronic device comprising first and second light emitting elements, a sensor, and a processor. The processor is configured to transmit a first command to the first light emitting element in response to the wrist-wearable device reaching a forward position relative to a user based on data received from the sensor and transmit a second command to the second light emitting element in response to the wrist-wearable device reaching a rearward position relative to the user based on the data from the sensor.

Abstract: Devices and methods for improved separation of small particles from other stock. The device includes a sifting tray assembly and means for vibrating the screen of the sifting tray assembly for separating components and a cryogenic fluid source and injection system for freezing the small parts to the point where they are solid enough to pass through the screen without adhering to the screen. The method entails use of the system to separate small particles in sifting trays while spraying the stock with a cryogen such as liquid nitrogen.

Abstract: A system is disclosed that includes a ball-throwing machine included within a first housing, a controller communicatively coupled to the ball-throwing machine and included within a second housing different than the first housing, a camera, and a non-transitory storage medium having stored thereon logic, the logic being executable by one or more processors to perform operations including: receiving information associated with a selection of a first training drill from the controller, responsive to receiving the information associated with the selection of the first training drill, causing the ball-throwing machine to impart motion to one or more balls in accordance with the first training drill, receiving multimedia data of a player captured by the camera, and performing a player recognition procedure to locate the player within the multimedia data.

Abstract: A ball throwing machine can include a hopper for receiving one or more balls and a ball delivery device. The ball delivery device can be used to throw or pitch a ball from the hopper to a user of the machine. The ball delivery device can include wheels to impart speed to the ball and a direction system to control the projection angle of the ball. The direction system can control at least one of the up and down angle and the side to side angle of the ball as it is thrown, among possibly other throwing parameters. A controller may be provided for controlling operation of the ball throwing machine.

Abstract: A goal apparatus comprising a cross bar, a first side post and a second side post is described. The first side post and the second side post are connected to the cross bar such that the first side post, the second side post and the cross bar form a plane (“a goal plane”). Further, one or more sensor pairs are coupled to the first side post and the second side post, wherein a first sensor pair of the one or more sensor pairs includes a first sensor and a second sensor. The first sensor is coupled to the first side post and the second sensor is coupled to the second side post and is also aligned horizontal to the first sensor. In addition, the first sensor pair is located in a first zone, wherein the first zone is a first portion of the goal plane.
