Abstract: Absorbent articles herein may provide a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet. The absorbent core may comprise at least one channel having a shape. The backsheet graphics may substantially match the shape.

Abstract: The invention relates to a device for accurately positioning an object, such as a mirror 3 used to precisely aim a laser. The invention uses kinematic principles to hold the object. Here a 2-2-2 kinematic bipod system is employed. The invention uses three actuators 5 to position the object. Each actuator acts as a bipod restricting the object in two of its six degrees of freedom. Each actuator has three degrees of freedom it can transmit to the object. The actuator can rotate on its single-axis flexure 7 so that the actuator cna rotate on one axis relative to support 4. Each actuator has a two-axis coincident flexure 8 on one end for allowing the object to be moved in two rotational degrees of freedom and the roller sleeve 50 allows a third rotational degree of freedom. Each actuator is positioned circumferencially about the central coordinate axis of the object to be moved, 120 degrees apart.

Abstract: A load balanced coolant fitting for allowing an inlet structure and an op support structure to be mounted relative to each other to communicate coolant fluid from the inlet structure to the optic support structure in such a way as to minimize vibration and jitter caused by the flowing of a coolant to be imparted to the optic structure.

Abstract: An apparatus 30 for kinematically mounting an optic 32, requiring more than three point support, to a structure 38. A holder 34 fixedly contains the optic 32. A ball 44, socket 46 and fastener 50 provide sole support of the optic 32 in three of the six degrees of freedom necessary for complete support. A ball 54, socket 56 and fastener 60 provide sole support of the optic 32 in two of the remaining three degrees of freedom. Two Belleville disc springs 64, a thrust washer 66, thrust bearing 68, one-half ball 70 and fastener 72 support the optic 32 on the structure 38 in the final degree of freedom without introducing redundancy in that final degree of freedom. By providing the capability of having numerous resilient support assemblies supporting the optic 32 in the final degree of freedom without introducing redundancy, heavy optics can be supported with very little structural or thermal distortions.

Abstract: The passageway selective detector mechanism and system of this invention comprises a mat positionable within a passageway, such as a doorway, gateway, or the like. Imbedded within the mat are magnetically operable electric switches which are electrically connectable to an alarm or signal member and to a source of electrical energy. Thus, when any of the switches is operated, the alarm or signal member is energized. The mechanism and system includes magnetic elements associated with selective personnel for operation of at least one of the electric switches as the selective personnel travels over the mat. The magnetic element may comprise an inner sole within the shoe of the selective personnel to actuate an electric switch, which actuates the alarm or signal member as the selective personnel steps upon the mat.

Abstract: A two-dimensional flexure gimbal-type coupling in which rectangular flexure members allow limited rotation about two mutually perpendicular intersecting axes. The coupling utilizes two pairs of flexure members arranged in two mutually perpendicular planes when unflexed, the planes intersecting along an axis lying between the flexure members of both pairs. Each pair of flexures are attached to respective spaced frame members along one edge. A coupling member is attached to the opposite edges of all the flexure members in such a manner that the edges of one pair of flexure members where attached to a frame member lie in a common plane with the edges of the other pair of flexure members where attached to the coupling member.

Abstract: An incident radiation absorber/reflector assembly having a mounting housing to which is adjustably secured an absorber body and a reflector element. An entrance opening, aligned with the reflector element, is formed within the body. The entrance opening is connected to a cylindrical cavity within the body by a tapered passageway which is offset from the longitudinal axis of the cavity. Any incident radiation intercepted by the reflector element is directed by the reflector element into the cavity where it is substantially absorbed by the absorber body.

Abstract: An incident radiation absorber having a plurality of cooled panels which provide for absorption steps for radiation reflected from the beam oscillation region of a laser. The panels are arranged in such an assembly array as to form a compact absorption system. Radiation absorbed is dissipated and reduced in intensity by the precisely set angles, surface coatings and cooling so as to render the radiation leaving the system as controlled, reduced to a harmless 21/2% and directed away from the oscillation region of the laser.
