A motorized, steerable, electrically-operated personal watercraft that includes a hull with a bow, stern, top deck surface, underside surface, and a support and steering console. The deck is configured to allow a user to lie prone on the deck with the user's chest located on or proximate the console. There are left and right steering control devices located at the left and right of the console, respectively. The steering control devices are configured to be manipulated by the left and right hands of the user. Motive power and steering are both provided through an electrically-powered water jet, which may be but need not be located at the stern. The water jet is mounted to a fixture that is configured such that the outlet nozzle of the jet can be turned left and right, in order to steer the craft to the left and right. Jet nozzle steering is accomplished by manipulation of the left and right steering controls. User-operable kill switches also located at the left and right of the console must be operated in order to operate the jet.

Generally discussed herein are devices, systems, and methods for smart weight-lifting devices. A weight-lifting pin may be configured for insertion into a weight plate of a weight-lifting machine, the weight-lifting pin comprising a radio transmitter, a movement sensor, and a distance sensor.

A cognitive/multisensory stimulation system simulates real sports action/job task scenarios for assessing, profiling, practicing, improving or rehabilitating cognitive function performance of athletes or individuals. Cognitive function improvement can be provided by: establishing with a subject a sensory semantic language for relating a number of sensory signals to corresponding possible actions, the sensory semantic language being essentially new to the subject; instructing the athlete to perform an task involving sport/job skills; providing to the subject during the task sensory signals requiring rapid discernment by the subject of the semantic meaning of the sensory signal to correctly chose one possible action; and determining whether the subject correctly responds to the selected sensory signal during the task; obtaining a cognitive-sensor reaction-time map over a visual field of the subject; and repeating the steps over multiple repeated tasks using selectively randomized sensory signals selected to progressively restore the cognitive-sensor reaction-time map a normal profile.

An electric walking assistance device is provided. The electric walking assistance device comprises: a support member comprising at least one movable component; a user area where a user can stand, wherein the user area is a ground area adjacent to the support member. The electric walking assistance device further comprises at least one gait monitoring module and at least one gait assisting module, wherein the at least one gait monitoring module and the at least one gait assisting module are on the support member, the user's body, an arbitrary point within the detection range covering a range of user activities or any combinations thereof.

The present disclosure provides a handle exercising device and a set of exercising devices. The handle exercising device includes a handle body, a chamber, a buckle portion, a release button, and two female buckles. The handle body has a top surface and a bottom surface. The chamber is disposed in the handle body along an axial direction of the handle body, wherein the chamber has an opening facing one end of the handle body. The buckle portion is disposed in the chamber and buckles a predetermined assembly inserting the chamber via the opening. The release button is disposed at the top surface of the handle body and connected with the buckle portion to release a buckling status of the buckling portion. The female buckles are disposed at the bottom surface of the handle body and arranged in parallel along the axial direction.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

An athletic training system (200) has a data recording system (202) and a data engine (204). The data recording system (202) is configured to record an athletic competition event. The event may have a first team of players competing against a second team of players. The data engine (204) is configured to receive data associated with the recorded athletic competition event. The data engine (204) processes the data and displays the data as a replay of the event in animated form.

Disclosed is a smart, physiology monitoring mouthguard (SPMM) system and method for capturing various physiological data of athletes in real-time for health monitoring. The system is configured to provide real-time and/or recorded physiological data of an athlete to a user, and may be configured to record physiological data of the athlete for later retrieval using sensors and communication systems. Sensors may be chosen based on the anticipated activity or sport, the health and age of the athlete, and size and power requirements of the device. Sensors may include accelerometers, gyroscopes, thermometers, hydrometers, pH, electrolyte (e.g., potassium, sodium, etc.) sensors, and the like. These and other sensors may be configured to measure different physiological data of the athlete, including impact, body temperature, hydration, illness, heart rate, and the like. In some embodiments, sensors on the mouthguard are integrated with external sensors (e.g., accelerometers on a helmet, chest-worn heart rate monitor) on the athlete to provide additional or more accurate physiological data.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.
