An electronic punching bag includes an elongate bag formed of resilient material, a microprocessor disposed in an interior of the electronic punching bag or at a periphery of the electronic punching bag, and a display screen that extends around more than half of the periphery of the electronic punching bag. The display screen is configured to receive signals from the microprocessor. The signals cause the display screen to display visual signals.

A programmable electronic sports target system. The system includes one or more target devices mounted to a goal with a net. Each of the one or more target devices has a programmable module disposed therein for controlling and operating the one or more target devices. A remote control system containing a computer and a database is connected to each programmable module to receive target sensor data from the programmable module of each of the one or more target devices for analyzing the data and for transmitting operational control data to the programmable module for operational control of the target devices having the programmable module disposed therein. Target application software within mobile communications devices receives target sensor data from the remote control device and to transmit operational control data to the remote control device.

The invention relates to a portable self-adjusting underwater booster with a life-saving device which includes a belt, a life-saving device and a propulsion device. The belt includes a rear end of the belt and a front end of the belt. A fastener is provided on the front end of the belt. The fastener is used to fasten the belt. The rear end of the belt is provided with a mounting plate, a first bag and a second bag at outer side. The mounting plate is provided with a connecting hole and an arc groove at outer side. The arc groove is provided with an arc rack. The life-saving device includes a compressed gas tank disposed in the second bag, a valve, and an airbag. The airbag is fixedly connected to the belt. The propulsion device includes an upper cylinder and a lower cylinder. The portable self-adjusting underwater booster with a life-saving device has advantages of having simple and reasonable structure, being convenient to use, safe and reliable, high degree of intelligence with life-saving device. It effectively solves the problem regarding the existing underwater boosters not having life-saving function.

An underwater striking bag device includes a bag having an annular upper compartment disposed in an upper section of the bag and receiving air therein, a neck extending through the upper section and communicating with a lower compartment receiving water therein, a removable cap connected to the neck, an air valve connected to the annular upper compartment to provide for filling air into the annular upper compartment, at least one handle connected to the bag for assisting in filling and removal of the water into the lower compartment.

A system, apparatus, and method for transporting an amusement attraction, such as an inflatable surfing attraction. A shipping container may be provided that is modifiable (e.g., has removable or rotatable elements such that it may be converted from a transporting orientation for containing one or more components of the attraction within for shipment to a deployed orientation whereby one or more of its elements may be used for setup and/or operation of the attraction. The attraction may incorporate an automatic inflating system that monitors pressure or other characteristics during setup.

A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.

A structure generally comprising a support structure with a rotating form is disclosed. The support structure may be an upright tube or other shape, and the rotating form may be a ring or other shape configured with the tube. Holes may be in the outer circumference of the tube and in the inner circumference of the opening of the ring. Pressurized air may pass into the tube and out its holes, and then into the ring. In this way, the air may apply a lift to the ring and may minimize friction between the tube and the ring, thus allowing it to rotate freely.

An inflatable sports training ball made as an inflatable exterior surface formed of an air tight flexible outer casing which, when inflated, defines an exterior surface; an interior air pocket surrounded by an interior liner defining a bladder, the interior liner made of an air tight and water tight rubber; an inflation and fill valve; and a solution filling a portion of the bladder, the solution being substantially heavier than air and occupying an amount of said interior volume wherein a pre-determined amount of the solution is forced into the interior air chamber of the sports ball with a pump and the resulting partially solution filled sports ball is used for training drills by a sports player.

A board paddling training apparatus for assisting in improving a user's paddling technique and strength. In particular, the board paddling training apparatus includes a buoyant board, such as a board adapted for surfing, bodyboarding, paddleboarding, or other board-related sport that entails paddling, and includes a resistance mechanism that creates drag or resistance against a user's paddle stroke. Some implementations of the resistance mechanism can be adjustable in order to create a variety of resistance against the user's paddle stroke and board movement.

A swim cap for persons having long hair includes a shell preferably having at least two interconnected compartments for receiving and encapsulating the hair of a user. The swim cap is secured around the head of a user by at least one draw string or adjustable band positioned within a channel near the open end of the swim cap as well as a chin strap extending downwardly from the cap. The interconnected compartments can be inflated to provide buoyancy. The shell further includes an outer layer and an inner layer defining a space therebetween that can also be inflated, or comprised of buoyant material, to provide buoyancy. A pump, compressed air canister or manual filler tube in communication with the interconnected compartments or space within the shell can be used to provide inflation. A pair of ear flaps extends downwardly from the swim cap around a user's head.
