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.

A trick scooter comprising a base plate, a support member, comprising a first end and a second end, a handle, comprising a first end and a second end, wherein the handle is attached to the second end of the support member. Furthermore, the base plate is manufactured of elastic and flexible material. Such a trick scooter is advantageous as it is lightweight, easy and safe to handle and does not damage the surroundings or cause injury to people nearby.

The present specification discloses an exercise system comprising a stable support purchase, such as a ballet barre, and an unstable support apparatus, such as a ball or a roller, wherein an individual may support a limb on the unstable support apparatus and selectively contact the stable support purchase for balance while performing an exercise, such as a ballet position, and an associated method comprising the steps of positioning at least one limb on the unstable support apparatus and simultaneously performing the exercise.

A camera for facilitating autonomous picture production includes an imager for capturing an image stream, a signal processor for processing the image stream into a plurality of image data paths, at least one image stream output, and a memory for cyclically buffering images of at least two of the plurality of image data paths, into separate circular buffers, respectively, and for buffering one or more output image streams of the camera. A camera for facilitating autonomous picture production produces a standard resolution and rate image stream and a slow-motion image stream of an action of interest.

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

An image-stream windowing method includes capturing, with a camera located at a fixed position and having a fixed field of view, a high-resolution image stream of an object that moves during said capturing. The high-resolution image stream includes a sequence of high-resolution frames. The method also includes determining, for each high-resolution frame of the sequence of high-resolution frames, a respective window, of a sequence of windows corresponding to the sequence of high-resolution frames, that encloses the object within said each high-resolution frame. The size and location of the respective window are determined based at least on the fixed position, the fixed field of view, and a position of the object. The method also includes generating a low-resolution image stream from the high-resolution image stream by cropping said each high-resolution frame with its respective window.

A high-speed skatemill with a movable skatemill belt that includes a movable skatemill belt mounted on the rotating drums and where the working area of the movable skatemill belt is supported by stationary rigid sliding pads with integrated distribution channels for distributing a compressed gas or gas mixtures into the injection openings or slits. The compressed gas or the compressed gas mixture optionally enriched with an anti-friction medium in the form of a vapor or aerosol or dispersion containing solid dust particles or solid microparticles is injected through the inlet openings. By means of the anti-friction applicator, the anti-friction medium is applied to the movable skatemill belt, which then transports the medium to the points of contact with the fixed rigid sliding pads. Stationary solid sliding pads can be cooled down by liquid and/or gaseous cooling medium circulating by default in the hollow support beams of the stationary solid sliding pads.

Portable markers for sports such as ice hockey. The portable markers have a short profile, are stackable, have a bottom surface with enhanced friction to prevent movement of the markers on the ice, and define an opening through which the toe of a hockey stick blade may be inserted so that the markers may be easily placed upon and lifted from the ice and transported together on the hockey stick.

There is disclosed a novel system and method for performance monitoring of athletes. In an embodiment, the system comprises a plurality of sensor modules mounted on different locations of an athlete, wherein at least one of the plurality of sensor modules is a master sensor module configured to interconnect with all other sensor modules to collect performance data for transmission to a computer system configured to collect the performance data. In an embodiment, a sensor module is housed in a cavity of a blade holder in at least one skate of a pair of skates worn by a hockey player.
