An emergency rescue equipmenthaving a harmonic reflector circuit comprising an antenna connected to a non-linear circuit via a matching circuitand a casing that in part enclose the harmonic reflector circuit, wherein the harmonic reflector circuit is configured to receive a signal at a receive frequency (fRX), and configured to transmit said received signal at a transmit frequency (fTX), where the transmit frequency is a multiple of the receive frequency, the harmonic reflector circuit wherein the receive frequency (fRX) is in an interval from a first frequency to a second frequency, where the first frequency is at least 800 MHz; middle second frequency is at least 34 MHz larger than the first frequency;the received signal is transmitted at the transmit frequency (fTX) with an output power (Pout) of at least 70% of the maximum available output power (Pmax).

A ski boot composed of a lower part or foot portion and an upper part or leg portion, suitable to enclose the lower part of the skier's leg, wherein the leg portion is hinged to the foot portion so as to rotate with respect to the foot portion around hinges defining a rotation axis. The leg portion comprises a closing lever suitable to block and/or unblock selectively the rotation of the leg portion with respect to the foot portion, and operatively connected to a base and an arm engageable in abutment against a pin fixed to the foot portion. The closing lever in the open configuration mutually moves the base and the arm away from each other forcing the latter against the pin to prevent a rotation of the leg portion backwards. The boot comprises traction means which operatively connect the base, the arm, and a fastening on the foot portion, the arm being placed between the base and the fastening. Said traction means comprise a cable at least partially extensible.

A ski boot of the kind comprising a substantially rigid outer shell and a cuff articulated to the shell is provided and further includes a locking device which can be switched between a first configuration, in which the rotation of the cuff relative to the shell is allowed, and a second configuration, in which the rotation of the cuff relative to the shell is prevented. The locking device of the ski boot also includes deadlocking means which prevents the locking device from being accidentally moved from the configuration in which it is, specifically when it is in the second configuration.

A ski boot is provided of the type including a substantially soft inner liner, a substantially rigid outer shell and a cuff articulated to the shell, and further including a spoiler articulated to the shell and arranged between the inner liner and the cuff. The ski boot includes a locking device for selectively allowing or preventing rotation of the cuff relative to the shell and, at the same time, for selectively allowing or preventing the movements of the spoiler relative to the cuff, and consequently also relative to the shell.

A ski boot comprising a lower part or shell, suitable for enclosing the user's foot and an upper part or cuff, suitable for enclosing the lower part of the skier's leg, wherein the cuff is hinged to the shell so as to rotate relative to the shell around hinges defining a rotation axis, forward, toward a tip of the boot, and backwards toward a heel of the boot, wherein the boot comprises fastening means suitable for selectively locking and/or unlocking the rotation of the cuff with respect to the shell depending on whether the user wants to switch from a skiing configuration to a walking configuration, respectively. Advantageously the fastening means comprise a slider interposed between the cuff and the shell, wherein said slider is fixed in rotation to the cuff and it comprises first and second end stops, placed at opposite sides of the slider, wherein the slider is movable in translation with respect to the cuff in order to move from the unlock or walking configuration, wherein the first and second end stops do not interfere with the rotation of the cuff with respect to the shell, to the lock or ski configuration wherein the first and second end stops abut against respective first and second abutment of the shell, wherein first abutment blocks the forward rotation of the cuff with respect to the shell and second abutment blocks the backward rotation of the cuff with respect to the shell.

A boot form for a hockey skate is made of multiple plastic materials having different hardness properties, or different flexural moduli, and is formed via an injection-molding process or another similar process. One or more of the plastic materials may be reinforced with fibers of glass, carbon, aramid, or another stiffening material to strengthen one or more regions of the boot form. For example, pellets of a first plastic material having a flexural modulus of approximately 190 MPa (e.g., a polyamide elastomer block amide) may be injected into a mold to form a softer upper region of the boot form. And pellets of a second plastic having a flexural modulus of approximately 20,000 MPa (e.g., a Nylon 12 with long glass fibers) may be injected into the mold to form a stiffer lower region of the boot form. Additional skate components may then be attached to the boot form.

A ski boot comprising: a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to be able to couple to a ski binding device; a rigid cuff which is shaped so as to enclose the lower part of the leg of the user, and is pivotally joined to the shell so as to be able to swing about a rotation axis substantially perpendicular to the midplane of the boot; and a cuff locking device which is located on the cuff and is selectively adapted to rigidly connect the cuff to the shell to prevent the cuff from swinging on the shell; the cuff locking device, in turn, comprising a movable arm which is pivotally joined to the cuff so as to be able to rotate to and from a locking position in which the movable arm extends downwards and arranges its distal end in abutment on an anchorage structure present on said shell, and an elastic assembly which is adapted to bring and elastically retain the movable arm in the locking position, and which basically consists of a telescopic stem that lies substantially on the rotation plane of the movable arm and is interposed between the movable arm and a fixed point on the cuff, and of an elastic opposing member that is fitted on the telescopic stem, and acts on the telescopic stem so as to bring and elastically maintain the telescopic stem in a maximum extension configuration.

A ski boot, comprising: a rigid ski boot shell; and a sole of the ski boot which comprises a free upper side, which protrudes forwards in the longitudinal direction of the boot and/or laterally beyond the ski boot shell, and a lower side, wherein the ski boot comprises a front attaching region which co-operates with a front part of a ski binding in order to secure the ski boot, and a front region of the ski boot stands upright on a planar base via the front attaching region, wherein the upper side of the sole exhibits a distance, orthogonally with respect to the base, of at least 25 mm at a front end of the sole of the ski boot, and the upper side of the sole has a distance from the lower side of the sole, measured perpendicular to the base, of 19 mm2 mm at a distance from the front end of the sole, measured in the longitudinal direction, of at least 28 mm, and wherein, with the ski boot standing upright on the base, the lower side of the sole has a distance from the base of at least 5 mm throughout, up to a distance of 40 mm10 mm from the front end of the sole, as measured in the longitudinal direction.
