A portable information terminal includes: a GPS receiver that receives a satellite signal, an pressure sensor that detects atmospheric pressure, and a control unit that computes a slope at every position within a measurement section based on satellite signal information from the GPS receiver, and atmospheric pressure information that is based on a result of the detection by the pressure sensor. Furthermore, temperature information that is based on a result of detection by the temperature sensor is generated at every position within the measurement section.
摘要:
An end piece for a pole and a pole including such end piece, the end piece including a basket including a housing for receiving a distal end of a shaft of the pole, as well as a locking ring for surrounding at least a portion of the housing. The housing is demarcated by a wall supporting at least one catch provided, at a first end, with a nub configured to extend within the housing, the catch being capable of assuming a plurality of configurations corresponding to various radial positions of the nub. The ring is shaped to limit the radial displacement of the first end of the catch outward of the housing when the ring is assembled to the basket.

A ski training apparatus includes a ski pole having proximal and distal ends. A first guide member is coupled to an upper surface of a respective ski worn by a ski trainee and includes a first receiver portion defining a first open interior area and an open top. A second guide member includes a cylindrical configuration defining open upper and lower ends and an open interior area. A spring connects the second guide member to the first guide member, the spring having a flexible configuration such that the second guide member is repositionable relative to the first guide member. The second guide member is configured to receive the distal end of the ski pole. The second guide member is operatively coupled to the first guide member by the spring such that the ski trainer is selectively in control of the trainee's ski by manipulation of the ski pole.

摘要:
A one piece composite tube having a hollow wall structure. The outside and inside of the tube have a standard surface and shape for bonding or fastening. The hollow wall reduces vibration and allows consistent flexure and torsion. The shape of the hollow wall may be tuned to maintain light weight and optimize strength for a given application.
摘要:
A stick assembly for sporting and/or recreational use includes an elongated shaft extending from a proximal end to a distal end. A handle is coupled to the proximal end of the shaft for allowing a user to grip the assembly. The shaft includes an engagement portion for engaging a surface and an extension portion separating the engagement portion from the handle. The shaft includes at least one curve. The engagement portion of the shaft comprises a flexible material. The shaft may also define an inner passage for accommodating at least one weight.
摘要:
The present invention concerns a ski pole. More specifically, the invention is directed to an aerodynamically favorable ski pole, which is designed to allow glue less or adhesive less directionally controllable fixation of replaceable means for limiting the sinking of the ski pole into ground surfaces.
摘要:
A ski pole basket, typically made of a polymeric material, that includes at least one generally rigid portion with a specifically shaped perimeter/interface configured to interface with the heel lip of a ski boot is described. When the basket is attached to a ski pole, a skier can use the pole to press down on the ski boot while he/she removes his/her foot from the boot while in a substantially erect standing position.
