摘要:
Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.

A bone plating system comprising: a plate, where the plate is low-profile and capable of contouring to a bone; a variable number of screw holes, locking or non-locking; at least one channel or tunnel through the plate; and at least one flexible device passing through the channel or tunnel and passing through soft tissue attached to the bone. The low profile plate, in combination with the flexible device passing through the surrounding soft tissue, functions as a tension band and acts to neutralize the muscle forces tending to pull the bone apart at a fracture. The low profile tension band plating system is targeted for periarticular tensile fractures for repair of the olecranon.

A dolly, according to various embodiments, comprises (1) a frame, (2) a nose plate that is attached adjacent a lower end of the frame; and (3) at least one wheel that is adapted to facilitate the rolling movement of the dolly relative to a support surface. In particular embodiments, the frame comprises: (1) a first side frame assembly; (2) a second side frame assembly that is spaced apart from, and co-facing the first frame assembly; and (3) at least one central connector that extends between the first side frame assembly and the second side frame assembly. The frame may be adapted to be selectively moved from a first orientation to a second, extended orientation in which a length of the frame is greater than a length of the frame in the first orientation.

A hand truck, according to various embodiments comprises: (1) a frame, (2) a nose plate that is attached adjacent a lower end of the frame; and (3) at least one wheel that is adapted to facilitate the rolling movement of the dolly relative to a support surface. In particular embodiments, the hand truck comprises: (1) a first axle support adjacent a first lateral side of the frame; and (2) a second axle support adjacent a second lateral side of the frame. The first and second axle supports are adapted to cooperate with the first and second axle supports of a like hand truck body to facilitate the positioning of the hand truck body into a nested relationship with the like hand truck body.

A projection weld element can include structure that prevents gases or other contaminants from passing through or around the weld element before, during or after attachment to a workpiece such as a vehicle body part. The projection weld element can include a barrel having a first axial end and a second axial end, a central axial bore being defined through the barrel from the first axial end towards the second axial end, and at least a portion of the central axial bore including an attachment structure, such as internal threads. A radial flange can extend from the second axial end of the barrel, with the flange including a distal axial face on a side of the flange facing away from the first axial end of the barrel and a proximal axial face on a side of the flange facing toward the first axial end of the barrel. The flange can include an annular projection weld ring formed along the proximal axial face of the flange on the same side of the flange as the barrel that extends from the flange. The weld ring can be configured to prevent transmission of contaminants, such as water, vapor, or other contaminants, from passing through the weld element to either side of a working piece to which the weld element is attached. A method for joining a working piece with a weld element can include joining a working piece with the above-described weld element and heating the structures to effect a projection welding between the working piece and the weld element. The resulting weld forming a continuous weld seal about the barrel portion of the weld element and between the weld element and the vehicle body part to prevent contaminants from transmitting through or around the weld element.
摘要:
We describe a switching power converter comprising a bipolar switching device (BJT or IGBT) switching an inductive load, and including a closed-loop control system. The control system comprises a voltage sensing system to sense a voltage on a collector terminal of the switching device and provide a voltage sense signal; a controller; and a drive modulation system coupled to an output of the controller for modulating a drive to the control terminal of said bipolar switching device responsive to a controller control signal; wherein said controller is configured to monitor changes in the sensed voltage during a period when said switching device is switched on and to control said drive modulation system to control the degree of saturation of said bipolar switching device when the device is switched on and hence improve turn-off times.
摘要:
A fastening system with an object including a securement structure with an extension element adapted to be compressed by a fastener. A portion of the securement structure extends above a first end of a compression reinforcement device. The extension element is adapted to be compressed by a fastener such that the portion of the securement structure is positioned substantially level with the first end and wherein the compression reinforcement device and the securement structure both receive compressive force from a fastener.
摘要:
A globally-addressable array of electronic circuit elements having distributed intelligence. Each circuit element location is connected to a common bus structure which can address each circuit element and transfer data to and from each element. Logic circuitry at each circuit element location recognizes data addressed to a respective circuit element location, and converts data received into an operating level for a respective transducer element. Data transfer to each element location can be made using conventional compression techniques. The data transfer can be bidirectional so that a sensed condition may be transferred from the location over the common bus structure.
摘要:
A hip harness for supporting upper body armor. The harness includes a hip belt, a frame, and a coupler. The hip belt is securable about the hips of a user of the body armor. The frame provides flexible support and has a lower end secured to the rear portion of the hip belt. The coupler is adjustably securable to the upper end of the frame. It has strips that fit through attachment loops on the back of the body armor to secure the harness to the armor.
