Provided is a training device capable of executing a plurality of operation modes, in which an operation rod is appropriately operated according to an operation mode. The training device includes the operation rod, a plurality of motors, a plurality of force detection units, and a plurality of first command calculation units. The operation rod allows a limb to move. The plurality of motors operate the operation rod in the direction of degree of freedom in which the operation rod can move. Each of the force detection units detects a corresponding force component and outputs a force component signal. The first command calculation units are connected to the corresponding force detection units. Each of the first command calculation units calculates a first motor control command on the basis of the corresponding force component signal.

This hockey stick toolbox comprises a casing, an assortment of tape; a pair of scissors; a handsaw and a miter box nested in that casing. The casing has spaced-apart notches for retaining a hockey stick steady in the miter box. The handsaw, the miter box, the assortment of tape and the scissors are particularly advantageous for trimming and customizing a new hockey stick on the-spur-of-the-moment by a parent of a novice player for example.

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.

An automatic batting training apparatus includes: a bottom part; a hopper assembly disposed on one side of the bottom part to sequentially discharge a plurality of balls stored therein; and a driving assembly disposed on the other side of the bottom part and including a transfer module adapted to transfer the balls discharged from the hopper assembly in a vertical direction and an ascending/descending module having a tee stand disposed movable upward and downward in such a manner as to allow the balls received from the transfer module to be seated one by one onto top thereof to perform tee batting.

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