User activity including both athletic activity (e.g., running, walking, etc.) and non-athletic activity (shopping, reading articles, etc.) may be monitored and tracked by an athletic monitoring and tracking device and service. The user activity may be used to award a user with an amount of virtual currency to encourage the user to continue various activities. In one example, users may use the virtual currency to purchase or otherwise acquire various products, services, discounts and the like. A user may track an amount currency earned and / or needed relative to an amount required to acquire a desired product or service. Additionally or alternatively, a visual appearance of a user device (e.g., a watch or athletic activity band) may change based on the user's activity level, an amount of virtual currency earned and the like.

The athletic garment has a first fabric for covering at least a portion of a first body segment, and a second fabric, different from said first fabric, for covering at least a portion of a second body segment; wherein the second fabric is a turbulence-generating fabric.

A skate sharpening device is provided which allows a grinding device to rotate with respect to a working surface of the device in both a cross grind configuration and a finish grind configuration. The grinding device pivots about a pin and is guided by a threaded stud protruding through an arcuate slot and securable using a flared, hand operated nut. A slidable rack attached to the grinding device is moveable in fore and aft directions relative thereto. A dressing tool may be attached to the rack and its forward position is governed by an actuating system. The actuating system allows a user to selectively inhibit forward movement of the rack to position the dressing tool at a suitable position to allow a dressing bit to contact a grinding wheel attached to and powered by the grinding device to dress the grinding wheel.

Protective gear for a wearer's body such as the joint of a limb, that has an attachment system with few components, and integrated with the protective gear. The attachment system uses straps that can be adjusted by a wearer once during a first use and, after removal, retain their adjustments for a second use by the same wearer. Securing the attachment system in place can be accompanied by an auditory signal.

A self-centering skate holder for clamping a skate blade from above and below which maintains the blade at a pre-determined height and parallelism. A handle is connected with a cable which is taut and extends around the circumference of the upstanding vertical member. The movements of the cable activate cam levers which rotate cams that move a pair of jaws towards or away from each other. The simultaneous movements of the cams ensure that the jaws move in unison and through a similar distance allowing a skate blade of any thickness to be clamped along the desired centerline. In an alternative mechanism, a tie bar extends between the jaws and is operated by a cam to induce equal and opposite movement of the jaws.

A device is provided for measuring the centre of a grinding wheel for use in setting the height of a skate blade. The device has a base, a support extending from the base, a slider block slidable along the neck between the base and a head block secured to an upper end of the neck, a dial indicator supported by the head block for measuring the position of the slider block along the neck, a lower roller, and an upper roller. The lower roller and upper roller are rotatably attached to the slider block and radially aligned with each other such that a portion of each roller protrudes from the slider block, wherein a clockwise tangential force imparted on the upper roller causes the slider block to slide along the neck, and the dial indicator to record the movement of the slider block, which enables the height of an object to be set on the dial indicator with respect to a rest position of the slider block.

A method is for using a skate-grinding device. The method provides an automatic sharpening system (10) that has grip members (14, 16) and a grinding wheel (28). A blade (18) of a skate (20) is inserted into a groove (19). The system is turned on. A motor (44) rotates the grinding wheel (28) and automatically moves the grinding wheel (28) within the groove to grind the blade (18). An electronic unit (86) measures a time the system (10) is used. A user of the system (10) is charged for the time measured by the electronic unit (86).

Described herein is a modular skate system that includes at least one modular skate component comprising a major surface, a core comprising a body formed from a first material, an outer layer formed from a second material, the outer layer surrounding at least a portion of the core, wherein the first material is different from the second material, and wherein the major surface comprises the outer layer.

The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a holder. A blade is placed into the holder. A grinding-wheel driving motor, in operative engagement with a wheel on a spindle, rotates a grinding wheel. A grinding assembly motor moves the grinding wheel in an x-direction towards the blade. A linear motor moves the grinding wheel from a first position to a second position in a z-direction without moving the grinding-wheel driving motor. The rotating grinding wheel engages the blade. The grinding wheel sharpens the blade.

The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a housing with an elongate opening defined therein. A blade is placed inside the elongate opening. The blade is tightened between self-centered clamp holders. The rotation of the grinding wheel is turned on. The rotating grinding-wheel engages an underside of the blade and automatically moves along the blade by following a contour of the blade. While the grinding wheel moves along the blade, a counter-weight provides a counter-weight to the grinding wheel. The blade is sharpened while the blade is stationary inside the elongate opening of the housing.

The invention relates to the technical field of physical training methods and equipment, and especially relates to an acceleration method and device for physical training. The method comprises the following steps: obtaining an initial output torque according to the mass of a load and a preset training speed and acceleration time needing to be reached, controlling the initial output torque of a drive mechanism through a variable frequency controller, and driving a winding mechanism to rotate to start to accelerate; monitoring the training speed of the athlete in real time, calculating real-timeoutput torque, judging the size of a first product of the real-time output torque, the load mass and the overload coefficient and a second product of the load mass and the safety coefficient, and when the real-time output torque is larger than the first product and smaller than the second product, adjusting the real-time output torque to be the first product; and when the real-time output torqueis greater than the second product, the athlete has an accident or the training requirement is changed, controlling the winding mechanism to brake through a brake mechanism.
