A system automatically detecting that an authorized game device or object with a rechargeable battery is close to or in contact with a wireless charging pod for the gaming device or object, automatically initiating and managing charging operations for authorized game device, and automatically deactivating the charging operations when the rechargeable batteries are fully charged, or when the authorized game device is moved out of wireless charging range.

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

A monitoring device performs a method of detecting a need for maintenance of an exercise machine comprising a time-of-flight, ToF, sensor. The method comprises obtaining a measurement signal from the ToF sensor at a predefined operating condition of the exercise machine. Based on the measurement signal, the method determines a measured distance between the ToF sensor and a reflective element in the exercise machine. The measured distance has been found to be responsive to accumulation of deposits on the ToF sensor and is thus evaluated by the method to detect a need for cleaning. The method thereby enables preventive maintenance.

A smart vehicle flock navigation system includes a plurality of smart vehicles configured to follow a leader smart vehicle, wherein the leader smart vehicle is configured to follow a target vehicle or a target driving plan; each smart vehicle being equipped with: obstacle detection and avoidance capabilities; vehicle-to-vehicle communication means for transmitting information about obstacles and evasive actions to following smart vehicles; a flock control module for adjusting the driving path of the smart vehicle flock based on transmitted obstacle information; a flocking behavior algorithm based on three independent rules: Separation, Alignment, and Cohesion, controlling the motion of each smart vehicle within the flock; and a distributed flocking operation mechanism utilizing wireless network communication for coordinating the behavior of the smart vehicle flock.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A playing surface monitoring system, comprising a playing surface; an image capture unit arranged for capturing images of at least part of the playing surface and persons or objects thereon; processing means for detecting said persons or objects and their relative location on the playing surface; means for discriminating between persons using the pitch and objects used for maintenance of the playing surface, and means for using the determined information for determining density of use and/or maintenance of the playing surface or one more parts thereof over a period of time.

The present invention provides a system for monitoring a physiological parameter of players engaged in a sporting activity. The system includes a plurality of reporting units, a controller, and a signaling device. The reporting unit has an arrangement of sensing devices that measure the physiological parameter of an individual player and generate parameter data. The controller receives the parameter data transmitted from each reporting unit and then processes the parameter data to calculate a parameter result. When the parameter result exceeds a predetermined value, the controller communicates with a signaling device that provides an alert to sideline personnel to monitor the player(s) in question. The system also includes a remote storage device for holding historical data collected by the system which permits subsequent analysis. The system can monitor a number of player physiological parameters, including the acceleration of a player's body part that experiences an impact and the temperature of each player.

A method for cooling a motor on a treadmill includes rotating a flywheel with a drive motor. A ring member coupled to the flywheel is be rotated with the flywheel. A pressure drop is generated in an annulus of the ring member between the drive motor and a lift motor. Intake air is drawn in a first direction across the lift motor toward the pressure drop.

A barbell comprising a bar member, a first side weight assembly and a second side weight assembly. The bar member has a first side sleeve region and a second side sleeve region opposite the first side sleeve region. The first side weight assembly includes a weight surface and extends over the first side sleeve region, and is rotatively coupled to the bar member through an inner and outer slidable engagement surface. The second side weight assembly includes a weight surface and extends over the second side sleeve region, and is rotatively coupled to the bar member through an inner and outer slidable engagement surface. The bar member includes a first and second surface enhanced region, the first surface enhanced region spanning a portion of the central region and the first side sleeve region, and with the second surface enhanced region spanning a portion of the central region and the second side sleeve region.
