An improved laryngoscope that is useful in endotracheal intubation. The laryngoscope includes an inner magnetic element that is situated at an end of the laryngoscope's blade and an outer magnetic element that is positioned on a patient's throat in such a manner that the interaction between the inner and outer elements attracts the end of the blade toward the patient's epiglottic vallecula when the blade is moved into the patient's throat. The blade also includes a magnetic bed located along its longitudinal axis. The magnetic bed is designed to interact with a metallic spiral tube and, by means of this interaction, guide the tube properly in the patient's inner air tract. The blade also includes at least three coplanar elements that able to rotate relative to each other. The adjustment of these elements increases the blade's usefulness for moving the patient's tissues and opening a passage to the patient's trachea.

A post and beam furniture construction has a number of support posts and a plurality of beams that interconnect the posts. Accessories, including storage shelves and cabinets, and work surfaces are releasably supported by the posts at various positions relative to the shelf length and the post spacing. Support brackets interconnect accessories and posts. Each post has at least two accessory support rails extending along the post length. A support bracket engages a selected rail. Spaced support bracket receptacles extend along a length of the accessory and a support bracket engages a selected bracket receptacle. The beams may be removed from respective posts without moving the posts and may also be length adjustable.

A portable, collapsible child booster seat for a vehicle comprises a collapsible seat member that removably rests on a vehicle seat with collapsible arm rests extending upwardly from opposite sides of the seat member. The seat member includes an upper seating surface supported on a collapsible scissors frame seat base. The seat base is raisable to a deployed position and collapsible to a storage position. The arm rests comprise horizontal arms pivotably mounted on raisable legs. The arm rests have a deployed position, wherein the legs extend upwardly from the seat base and the arms extend forwardly, and a collapsed position, wherein the legs and arms are in a generally horizontal position adjacent the sides of the seat base. The arm rests and seat base are operably interconnected, such that raising or lowering the arm rests between their deployed and collapsed positions causes deployment and collapse of the seat base.

A compact and efficient ultraviolet laser source based on a optically-pumped solid-state or fiber laser that produces near-infrared output light suitable for nonlinear frequency conversion. The infrared laser output is frequency tripled or quadrupled to produce light in the ultraviolet wavelength range (200 nm to 400 nm). The novel technology is the use of highly efficient periodically poled nonlinear crystals, such as stoichiometric and MgO-doped lithium tantalate and lithium niobate. As opposed to conventional frequency-converted UV laser sources, which have high power consumption, high cost, and low efficiency, the laser sources of this invention utilize high efficiency nonlinear conversion provided by periodically poled materials and allow lower-cost architectures without additional focusing lenses, high power pump diodes, etc.

A modular mounting system for institutional or classroom furniture or fixtures includes mounting rails that are attached to a wall surface in a horizontal orientation and that are vertically spaced. The mounting rails have a flat wall-mounting portion, with upper and lower T-shaped sections projecting therefrom, forming upper and lower U-channels and a central C-channel. The wall-mounting portion has a lower chamfered edge. Sections of mounting rail are aligned by a spline inserted into the C-channel. The system is infinitely adaptable to a wide range of changing uses for the classroom, with each element of the modular classroom furniture easily mounted to or removed from the mounting rail with only a screwdriver. The selectable elements include a flat panel accessory that rides between the upper and lower mounting rails, an accessory tray, and vertical rail members and casegoods in various configurations that attach to one or both rails.

An implement for clearing debris from a drain cup or basket strainer in a sink includes an upright handle for gripping and operating the implement. A cutting member configured to cut up the debris and force it through the drain cup or basket strainer is mounted on a lower end of the handle. The cutting member includes a centrally disposed recess for the strainer basket handle or the basket attachment nut in the drain cup. A plurality of radially extending grooves are formed in a lower surface of the cutting member with cutting edges being formed on the edges of the grooves for cutting the debris and forcing it through the drain cup or basket strainer. The recess in the cutting member permits the blades of the cutting assembly to reach the base of the strainer without interference from the strainer basket handle or attachment nut.

A modular flow through or push back storage rack system has a transfer assembly with a plurality of modular carriage units located in a warehouse storage bay. The carriage units are arranged in side-by-side pairs. Each side-by-side pair of carriages defines a space between the carriages. Further, the side-by-side pairs of carriages are arranged in end-to-end alignment. Each carriage is preferably provided as an endless loop link track. An inter-carriage transport unit extends between a space between one side-by-side pair of carriage units and another space between an adjacent pair of side-by-side carriage units. Each of the carriage units and the transport unit may be supported by a cross beam. The transport unit preferably extends between adjacent cross beams of adjacent pairs of carriages. The transfer assembly maintains the storage units at a substantially level plane and may modulate a transfer speed of the storage units between adjacent carriages.

A system for managing digital interactions comprising an identity module for creating an identity, wherein the identity includes a unique identifier associated with a first party and a plurality of proposed terms for a relationship with a second party; and a relationship module, in communication with the identity module, for receiving and evaluating the plurality of proposed terms, including accepting or rejecting the plurality of proposed terms and, if accepted, for allowing the first party to communicate with the second party in accordance with the plurality of proposed terms.
摘要:
Mud flap having a plurality of laterally spaced, vertically extending vanes defining a plurality of vertically extending channels on the front side of the flap for directing water and debris from a wheel in a downward direction toward the roadway and not to the rear or sides of the flap, and vertically extending slotted openings in the channels of a size permitting air to pass through the openings to the rear of the flap and preventing water and debris from doing so. In some embodiments, vertically extending deflectors are positioned to the rear of the slotted openings for directing any water and debris passing through the openings in a downward direction toward the roadway.

A cremation urn display has a floor, a top, and a perimeter sidewall. A viewable portion on the top or sidewall includes fasteners upon which a memorial display is surface mounted. The display includes a mounted butterfly fixed in a container having a viewable display panel. No recess need be formed in the top or sidewall to accommodate mounting of the display. The display is removable from the urn, and contains a sealable capsule for retaining a portion of cremated remains.
