Abstract: Web objects, such as media files are sent through an adaptation server which includes a transcoder for adapting forwarded objects according to profiles of the receiving destinations, and a cache memory for caching frequently requested objects, including their adapted versions. The probability of additional requests for the same object before the object expires, is assessed by tracking hits. Only objects having experienced hits in excess of a hit threshold are cached, the hit threshold being adaptively adjusted based on the capacity of the cache, and the space required to store cached media files. Expired objects are collected in a list, and may be periodically ejected from the cache, or when the cache is nearly full.

Abstract: A chassis for a gliding sport element, such as a skate, and, more particularly, such as an in-line roller skate, which includes such chassis. The chassis includes at least one support surface capable of receiving a boot and at least one lateral flange having at least one stiffening rib formed on at least one of the flanges. The gliding member(s), such as wheels, are mounted to the lateral flange(s).

Abstract: A frame for skates and the like with a structure that includes at least one bearing surface engageable by a boot or the like, and a side flange. One of more ground-engaging members are to be attached to the frame. The components of the structure of the frame are made of at least two at least partially mutually assembled materials having different mechanical properties.

Abstract: A frame for skates and the like with a structure comprising at least one bearing surface (3, 4) engageable by a boot or the like, and a side flange (2) comprising means for attaching one or more ground-engaging members. The components (3, 4-2, 8) of the structure are made of at least two at least partially mutually assembled materials having different mechanical properties.

Abstract: An article of gliding equipment, such as for practicing ice skating or hard surface skating, of the type that includes a frame defined by two lateral flanges on which are attached the gliding member or members, such as a gliding blade or wheels, and the upper plate adapted to be made integral with the external sole of the skater's boot. The frame is formed as a hollow body, hermetically closed in both the transverse and longitudinal directions, simultaneously defining the lateral flanges, the upper plate, and the end parts.

Abstract: The chassis includes at least one support surface capable of receiving a boot and at least one lateral flange to which the gliding member(s) is (are) attached, as well as at least one stiffening rib obtained on at least one of the flanges by pressing. The manufacturing method includes the steps of cutting in a metallic sheet a form corresponding substantially to the completed form of at least one portion of the chassis, and obtaining at least one stiffening rib by pressing in the portion of the chassis.

Abstract: A roller skate having a boot provided with a rear stiffener and including a rigid collar journaled on the rear stiffener and adapted to surround the lower part of the leg. The upper of the boot is a low upper and the journal of the rigid collar on the upper is located in the area of the upper end thereof, and substantially in the area of the malleoli.

Abstract: The invention relates to a roller skate boot, of the type constituted by an upper provided with a rear stiffener, and including a rigid collar journalled on the rear stiffener of the boot and adapted to surround the lower part of the leg. According to the invention, the upper of the boot is a low upper, and the journal of the rigid collar on the upper is located at the level of the upper end thereof, and substantially at the level of the malleoli.

Abstract: In-line roller skate constituted by a longitudinal frame on lower portion of which a plurality of skating wheels are arranged, and by a boot constituted by a shell base extended toward the skater's ankle by an upper, and a sole of which is associated with the frame, directly or via an up plate of the frame or a cradle, wherein a detachable linkage arrangement is interposed between the frame and the boot sole, whether or not via a plate or cradle, and is constituted by at least one wedge-shaped lateral flange obtained on an upper portion of the frame and capable of cooperating with a corresponding housing of the sole, plate or cradle, via a tightening member in order to obtain a linkage by progressive wedging effect, resulting in an automatic backlash elimination, between the flange of the frame and the sole, plate or cradle.

Abstract: An in-line roller skate boot obtained from an external sole and adapted to be affixed to the upper plate of a frame on which the wheels are arranged, and from which sole an upper covering the foot extends in the direction the skater's ankle, wherein the upper is composed of a first portion made of a relatively rigid material coming from the sole to form a shell base provided at its upper portion with a longitudinal opening extending from a raised zone that forms a rear stiffener up to the vicinity of an opposing end tip, and of a second portion constituting a vamp made of a relatively flexible attached material fixed on the circumference of the longitudinal opening of the shell base to cover a forefoot and contribute to obtain, together with the shell, the boot upper.

Abstract: A sport boot having a shell base with its sole and an upper that is provided with at least one tightening device mounted on a strap to surround the lower part of the skier's leg, on the one hand, and in its rear portion with at least one adjustment arrangement enabling it to adapt to the morphology of the rear zone of the lower part of the leg. The boot upper has a rigid lower element topped and connected by a linking element to a flexible upper element that is provided with at least one strap with its tightening device, and with at least one deformable portion. The deformable portion is located above the element in correspondence with the back zone of the lower element, such that by tightening the strap on the lower part of the leg, such portion presses against the rear zone of the latter by adapting to its morphology.

Abstract: The shoe is of the type constituted by a shell base adapted to receive the foot of the user and a upper-collar in two portions journaled on the shell base, and including elements for mutually bringing together and latching the two portions of the upper in the tightening position around the lower leg.

Abstract: A device for closing a boot, in particular a ski boot, designed to hold two sections of the boot together and comprising, first, a control lever carried by a plate made integral with one of the sections to be joined together, and second, on the other section, a rack, in one of the teeth of which a hooking device is designed to be engaged, this device being connected to the control lever by an inextensible tie rod. The hooking device has two hooking ends and is connected to the tie rod by a connection block on a pin belonging to which it rotates asymmetrically in a plane substantially parallel to that of the boot surface, the hooking ends being equipped with catches.

Abstract: A boot and a boot closure device adapted to bring two flaps of the boot close together including a control lever borne by a plate affixedly connected to one of the flaps, a rack connected to the other flap including a complementary arrangement for adjusting its position with respect to the lever. The arrangement for adjusting the rack are constituted by an adjustment zone that includes a buttonhole-shaped oblong slot obtained on the flap of the boot and demarcated by two circular end zones connected by a straight portion and whose diameter is equal to that of a locking pin affixed to the rack, and provided with a flat portion that is oriented perpendicular to the rack longitudinal displacement axis. The rack can be displaced, in view of its adjustment, from one end to the other of the buttonhole, after a rotation at 90.degree. with respect to its longitudinal axis, to allow for its free sliding in the straight portion of the buttonhole, and locked in either one of the circular end zones by a 90.degree.
