Abstract: The method governs the operation of a home automation installation comprising a portable remote control, a relay and home automation appliances, and in which at least some home automation appliances can receive, by wireless channel, control commands sent by the portable remote control. The method is such that control commands can be sent selectively according to a scenario to the home automation appliances over the same communication bearer by the relay when the latter receives a specific command sent by the portable remote control to the relay.

Abstract: The command-transmitting device comprises control buttons (11, 12) and a movable control element (2b) movable in two directions along a theoretical axis of operation (D1), these control buttons and this movable control element being arranged on a first face (24) of the transmitting device, in which device the buttons (11, 12) are positioned outside of an exclusion zone (A) defined by two straight lines (C1, C2) intersecting in the center of the movable element and forming an angle (?) of 60°, the bisector of which is parallel to the theoretical axis of operation, and by a circle (21) whose center is on the center of the movable element and whose circumference is separated from the latter by a distance (d) of 20 mm, and the buttons (11, 12) controlling the movements of the slats in opposite directions are arranged on either side of the movable element (2b).

Abstract: The motorized blind (4) device (1) with orientable slats (5) comprises an orders transmitter (2) and an orders receiver (6) which is attached to the motorized blind, the orders transmitter (2) comprising a first control interface (2a) and a second control interface (2b). This device is one which comprises means of interpretation for differentiating between the orders to translate and to orient the slats on the basis of the actions performed on the two control interfaces, in which the second control interface (2b) comprises an element (14) that can be moved in two opposite senses along substantially one and the same first direction and in which two electric contacts are respectively actuatable by movement of the element (14) in the first sense and in the second sense. Such a device is simple, inexpensive, multi-purpose and its ergonomics for orienting the slats is intuitive.

Abstract: The invention relates to a method of disabling the keyboard keys of a command-emitting device. The inventive method is characterised in that it comprises repeated iterations of the following steps: the automatic disabling of at least some keys on the command-emitting device once a command has been sent and the cancellation of said key-disabling operation by means of a specific action on the command-emitting device. One such method can be used to disable the keyboard keys of a command-emitting device when said device is being placed in a pocket or bag.

Abstract: An apparatus for retaining a snowboard shoe on a board which includes a first anchoring device for the sole of the shoe; a second anchoring device affixed to the sole; a base affixed to the board and on which are mounted an arrangement for rotationally guiding and vertically retaining the first anchoring device and a mechanism for latching the second anchoring device, the mechanism including a jaw member having a housing for receiving the second anchoring device, and a latch journalled on the jaw member. The latching mechanism includes an elastic return device biased during the displacement of one portion at least of the latching mechanism which is driven by the thrust exerted by the second anchoring device moving vertically, substantially along an arc whose radius is equivalent to the distance separating the two anchoring devices during the tilting of the shoe about the axis of rotation of the first anchoring device.

Abstract: A device for modifying, dynamically, the pressure distribution of a ski, such as an alpine ski, along its sliding surface. The ski is equipped with front and rear binding elements and support elements for the front and rear ends of the sole of the boot. The device includes a sensor element in contact with the sole of the boot, and additionally, movable along a vertical direction, a flexion device to generate a flexional moment on at least one front or rear end of the ski, and a connection device between the sensor element and the flexion device to transmit, to the flexion device, at least one part of the vertical thrust of the boot sensed by the sensor element.

Abstract: An interface device between a ski and front and rear bindings (2, 3) designed to hold the ends of a boot in place on the ski. The device comprises a plate (13) with an elongated the central part (14) which extends above the upper surface of the ski in the area of the runner. A first end (15) of the plate is fastened to the ski, and a second end (16) is attached to the ski by a block of damping material (17) mounted in a sandwich configuration between the end of the plate and the ski. The block of damping material is preferably provided in order to function under compression and shearing action.

Abstract: A cross country ski in which, in the central portion of the ski, in the gripping zone of the boot, the heel zone acts as a support of the foot during a sliding phase, and a metatarso-phalangian support zone of the impulsion in the impulsion phase of the ski, a transverse slit is arranged, crossing the ski. The slit defines two flexion beams, upper and lower, respectively, in the thickness of the ski. This arrangement enables, during the impulsion phase, a good flattening on the ground of the lower beam and thus of the sole portion of the ski, i.e., the waxing chamber. The efficiency of the impulsion is thus substantially increased without affecting the sliding phase.

Abstract: A ski and a method of forming a ski. The ski includes a lower element and an upper element, each having the shape of a beam casing. The lower element has an upper surface that has either a longitudinally extending groove or a longitudinally extending projection and the upper element has a lower surface that has a groove or a projection that has a transverse cross-section that is respectively complementary to a transverse cross-section of the groove or to a transverse cross-section of the projection of the lower element, and in which the groove or projection of the lower element is nested in the projection or groove, respectively, of the upper element. Depending upon the nature of the desired response characteristics of the ski, the interior of the upper and lower elements can be selectively filled with specific materials or left empty.

Abstract: The cross-country ski according to the invention is characterized by a relatively regular curvature of the lower surface of the ski, i.e., a curvature such that the modules of variation of slope of the lower surface of the ski is less than 9.10.sup.4 cm.sup.-1 when the ski is at rest. Simultaneously, the front zone of the ski has a relatively high rigidity. Likewise, the rear zone can be relatively rigid. Preferably, the lateral surfaces of the ski are hollowed. Such a ski structure is particularly well adapted to obtain a good gripping of the edges, a good sliding on the edges, and a good sliding in direct tracks.

The anchoring mechanism (6) has at least one upper surface (6d) which forms an upward and rearward sloping ramp, and which is maintained in contact with at least one activating element (4d) fitted on the upper part of the housing (4) and capable of sliding longitudinally on the upper surface (6d) constituting the inclined ramp. Longitudinal play is provided between the housing (4) and the anchoring mechanism (6).

Abstract: System for binding a shoe or boot onto a cross-country ski. The system includes an upper support plate which is movably mounted along a direction having a component which is substantially perpendicular to the ski. The system further includes an elastic means for elastically biasing the movable support plate in a direction separating it from the ski.
