Methods and apparatus are disclosed for detecting and measuring performance characteristics and metrics of participants and vehicles. These performance characteristics and metrics include, but not are limited to, airtime, g-force, spin, rotation, drop distance, acceleration, and video and still images. These vehicles include, but are not limited to a snowboard, ski, skateboard, wakeboard, motorcycle, bicycle, ice skates and rollerblades. In one implementation, a camera provides near real-time images and video footage of a participant's actions on a vehicle which can be correlated with performance metrics. The camera may be located on the participant, the participant's vehicle or other equipment, or from some other observation point. The images recorded by the camera can be downloaded to a recording or other storage device to produce memorabilia (e.g., a CD ROM, or video cassette). If desired, the images can be sent in real-time through an event system and network (e.g., using a radio or other transmitter) to television, the Internet, and to other locations for producing the memorabilia or for providing images to television display devices, such as those located in a ski lodge for entertainment purposes or in a coach's or personal trainer's office for training purposes.

Ceramic bodies can be made by providing an initial green body of ceramic; and machining the initial green body to provide a machined green ceramic body. Embedding the initial green body in an embedding mass can be avoided. The initial green body can be bisqued, infiltrated an adjuvant such as machining wax, removing the infiltrated body, and machining it. Highly detailed ceramic products can be generated. The machined green ceramic body may be fired and / or further processed to provide a more finished ceramic body. Examples include a femoral component for a posterior stabilized knee implant, a component body for an artificial rotation device containing knee implant prosthesis a dental implant or bridge, an ice skating blade, and so forth. Zirconia ceramics are advantageously employed, for an example, Mg-TTZ.

The present invention discloses a coaster cycle having a front half which works similarly to a bicycle wherein it has handle bars that turn the front wheels. The front wheel turns left and right and also leans in both a left and right direction. The front wheel leans left to right and is connected to the rear wheels by a frame having multiple pivotal couplings so that the rear wheels lean left or right with exactly the same angle as the front wheels. The leaning of the front and rear wheels in concert gives the frame a unique design which allows it to make left and right high G-force turns in a very stable manner. Additional embodiments are disclosed which comprise twin, internal combustion engines being placed on the rear wheels of the vehicle in order to power the vehicle which also have independent thumb control throttles for controlling the rear wheels individually. An additional embodiment comprises having snow skis attached to the underside of the vehicle to allow it to be used on snow and also having ice-skate like members attached to the underside of the vehicle to allow it to be used on ice.

A skate blade has a front curved section having a front balance point, a rear curved section having a rear balance point, and a middle section having a center balance point. Each balance point is a point on the skate blade over which a skater's center of gravity lies depending on the skater's position. The skate blade is shaped such that the middle section is substantially flat. Additionally, the blade is shaped such that more of the blade extends away from a blade holder at the rear balance point than at the front balance point.

An ice skate blade assembly comprising: (a) an ice skate blade comprising first and second hooks projecting upwardly; (b) a blade holder having a bottom portion having a longitudinal groove extending therealong for receiving the upper edge of the ice skate blade and wherein the bottom portion further defines a recess extending upwardly from the longitudinal groove for receiving the first hook; and (c) a single actuator having a wall accessible by a finger of a user, a resilient portion having an end wall facing a section of the inner surface of the second pedestal and a base with an inner wall and a bottom wall having an upper surface, an end and a bottom surface, wherein the inner wall and the bottom wall define therebetween a channel opens to the bottom aperture for receiving the second hook.

A system for alerting a skater when the skater's feet touch during a maneuver. The system comprises a wrap that bears a pocket positionable on an item of footwear, such as an ice skate. The wrap includes lateral portions extending around the ankle of the skate and may further include an instep strap coupled to the lateral portions and extending beneath the skate. The system further includes a contact device in communication with an indication device. The contact device is configured to detect an amount of contact from a nearby object, such as a skater's other foot. Upon detecting the amount of contact, the indication device provides a human perceptible indication to the skater that indicates that a sufficient amount of contact was made to trigger the contact device.

A molded insert, and methods for forming same, for an arch cavity of a boot, such as, but not limited to ice skating boots, or an arch cavity of a shoe, such as, but not limited to exercise, therapeutic, or physiological footwear, is described. The molded insert can be formed of any moldable material that is substantially firm, yet comfortable, when cured or dried.
