A protective helmet is described comprising: an outer layer (1); an inner layer (5) for contact with a head of a wearer; and an intermediate layer (3, 4) comprising an anisotropic cellular material comprising cells having cell walls, the anisotropic cellular material having a relatively low resistance against deformation resulting from tangential forces on the helmet. The anisotropic material can be a foam or honeycomb material. The foam is preferably a closed cell foam. The helmet allows tangential impacts to the helmet which cause less rotational acceleration or deceleration of the head of the wearer compared to helmets using isotropic foams while still absorbing a significant amount of rotational energy.

An article of footwear including a sole and an upper, the upper including a seat adapted to nest the user's heel, the seat including a first stiffener, and an arrangement for varying the size or volume of the seat provided by the first stiffener, between an expanded position, for which the volume of the seat is relatively large, and a retracted position, for which the volume of the seat is reduced.

The pipe racking system is designed to handle drilling tubulars (primarily drill pipe and drill collars) between the racked or setback position and the well center. The racking system can mechanically grasp a stand of pipe, lift the pipe sufficient for free movement, and deliver the pipe to either the setback area for storage or to well center to be added to the drilling string. The purpose of this newly developed system is to move pipe safely and efficiently in the vertical position for drilling operations. Together with the use of its mechanized fingerboard, the system automates the process of handling and storing pipe vertically, thus eliminating the need for a worker at the racking board level. The system is capable of being installed within the masts of smaller rigs and may remain installed in the mast during rig moves thus minimizing any disassembly for rig-down.

The present invention provides soles, platforms, or inserts incorporated into footwear, preferably athletic footwear, designed to promote a more efficient running technique by an energy-translating sole comprising one or more angular displacement members, balance-thrust members, and counterbalance as well as conventional features. Systems and methods of the present invention promote more efficient running technique by facilitating foot-strike to occur at a point under and behind the runner's center of gravity. This may be accomplished, for example, by a foot-strike member, angular displacement member and balance-thrust member working cooperatively to displace the runner's center of gravity and translate gravitational, inertial and ground reaction forces, as well as muscular tension forces, into linear momentum.

In a hand-guided electrical tool 3 with a housing 2 that has a receiving collar 20 embodied on it and with a guard hood 1 that can be attached to the receiving collar 20 and has a clamping strap 16, which can move freely around the receiving collar 20 in a first position and rests snugly against the receiving collar 20 in a second position, a secure connection between the guard hood 1 and the housing 2 is achieved by virtue of the fact that the receiving collar 20 has at least one protrusion 21, which protrudes beyond the second area in the radial direction away from the spindle axle 5, and between the protrusion 21 and the housing 2, there is a distance h, which approximately corresponds to the width b of the clamping strap 16, and by virtue of the fact that that the clamping strap 16 has at least one indentation 12 so that the first diameter d1 of the opening 10 of the clamping strap 16 in the vicinity of the indentation 12 is greater than the second diameter d2 in the remaining region, wherein the first diameter d1 is of such a size that the clamping strap 16 can be moved over the protrusion 21 and the second diameter d2 is of such a size that the clamping strap 16 cannot be moved over the protrusion 21.

Joint temperature monitoring and control systems and methods are described herein in which the temperature of a fluid within a body or joint space is determined and / or monitored despite the energy generated during treatment by an ablation probe. One or more temperature sensors are positioned along the probe proximally of the electrode assembly and measure the temperature of an electrically conductive fluid without being overly influenced by the surgical effect occurring proximate the electrode assembly. The controller coupled to the probe can also be configured to set temperature limits and treatment times as well as moderating joint temperature by altering the electrically conductive fluid flow.

A radiofrequency perforation apparatus for creating a channel at a target location in a body of a patient, the radiofrequency perforation apparatus being usable by an intended user having a hand, the radiofrequency perforation apparatus comprising: a handle graspable by the hand; a distal portion, the distal portion defining a distal portion length, the distal portion including an electrode and an electrical insulator extending from the electrode; and a force transmitting portion extending between the distal portion and the handle, the force transmitting portion defining a force transmitting portion length, the force transmitting portion length being larger than the distal portion length, the force transmitting portion having a force transmitting portion flexural rigidity of at least about 0.016 Nm2; whereby the force transmitting portion has a force transmitting portion flexural rigidity allowing the transmission to the handle of contact forces exerted on the distal portion when the distal portion contacts the target location to provide tactile feedback to the intended user.

A safety steering mechanism for a steering column, with a steering-column comfort adjustment having linear positioning devices, and provided with safety devices designed such that, in an accident situation, at least an end area of the steering column can be moved away from a driver's position. The linear positioning devices include load absorption devices and / or withdrawal devices regarding the movement of at least the end area of the steering column away from a driver's position. An operating method for a safety steering mechanism for a steering column that can be adjusted by a comfort adjustment in accordance with the requirements and / or wishes of a driver by means of linear positioning devices and of which at least an end area of the steering column can be moved away from a driver's position in an accident situation. The movement of at least the end or the steering column away from a driver's position is braked in an accident situation in a load-receiving manner by load absorption devices contained in the linear positioning devices.
