Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the absorbent articles have a percentage of stretch in the lateral direction at the widest portion in the front region of the article and / or in the back region in the range of from about 25% to about 150%. Additionally, at least about 70% of the above stretch resides in a first edge zone and in a second edge zone of the chassis. The first edge zone and the second edge zone are separated by a middle zone. The middle zone, which has the same length as each edge zone, is stretchable, but to a lesser extent than the edge zones. Through this construction, the absorbent article exhibits improved fit and appearance. Of particular advantage, the carefully controlled stretch properties prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.

A garment including a body of fabric having a waistband and at least two seams that extend from the waistband and a support structure that is connected to the at least two seams and the waistband is provided. The support structure further includes a pocket and a tape connected to the pocket that prevents elongation of the support structure between said at least two seams during the wearable life of the body of fabric.

Devices and methods having a cooling material and reduced pressures to treat biological external tissue using at least one energy source are disclosed. The cooling material may be water, ethyl alcohol, and / or any other material having a vapor pressure below atmospheric pressure. The energy source may be incoherent light, coherent light, a radio frequency, ultrasound, a laser, and / or any other type of energy that can be applied through the device. The features of various embodiments of the device include the generation of positive pressure and / or negative pressure through one or more pressure conduits, the application of an object within a recess of the device, and measurements through various sensors on the device. These sensors may be monitored and / or controlled through a display element having rows and columns of pixels on the device. The device may be a handheld device or an add-on to existing devices in some embodiments, and may include skin color sensors, temperature sensors, motion sensors, vapor pressure sensors, material sensors, and / or capacitance sensors.

The invention discloses a rotating shaft mechanism which comprises a rotating shaft group, fixing parts and sliding parts, wherein the rotating shaft group comprises at least two parallelly arranged rotating shafts; the fixing parts are disposed on the two sides of the rotating shaft group; and the sliding parts are used for connecting the rotating shaft group with the fixing parts and at least disposed on one side of the rotating shaft group. When the rotating shafts at the symmetric positions are close to or far away from each other, due to the action of the sliding parts, the distance between the rotating shaft group and the fixing parts changes in the length direction of the rotating shaft mechanism. According to the rotating shaft mechanism, the sliding parts and the fixing parts are additionally arranged on the basis of an original rotating shaft mechanism. The sliding parts and the fixing parts can offset the displacement change generated by the movement of the rotating shafts being close to or far away from each other, it is guaranteed that the length of the outer side of the rotating shaft mechanism is unchanged, and a flexible screen laid on the rotating shaft group and the fixing parts is not stretched or compressed. Therefore, the rotating shaft mechanism can normally cooperate with the flexible screen for use, and the damage to the flexible screen is avoided. The invention also provides an electronic product with the rotating shaft mechanism.

An elastic dog leash and coupler utilizes brightly colored florescent latex tubing for a major portion of the leash and coupler. The tubing is mounted between rings. A monofilament nylon line is mounted within the tubing and connected to the rings. The monofilament line has a length significantly greater than the unstretched length of the tubing, and limits the degree to which the tubing may be stretched. With respect to the leash, a nonstretchable webbing handle is attached at one end and a stop section of the leash is attached at the other end. The coupler is comprised of a plurality of sections of tubing mounted to a ring, which may be attached to the end of the leash. The other ends of the tubing of the coupler are provided with nonstretchable webbing material which may be utilized as a stop section for the coupler leash. The webbing material may be provided with a reflective stripe for additional safety at night.

A resistance training exercise device, system and method having at least one elastic, elongated and hollow cord with a tether secured to each end of the cord and a limit band in the 3 cord to limit the length that the cord may be stretched.

An article includes a knitted component. The knitted component includes a knit element that is configured to stretch between a neutral position and a stretched position. The knitted component also includes a tensile strand. The tensile strand is at least partially inlaid within the knit element. The tensile strand includes a portion that is arranged as a stretch limiter element that is configured to move between a slack position and a taut position as the knit element moves between the neutral position and the stretched position. The stretch limiter element is in the slack position when the knit element is in the neutral position, and the stretch limiter element is in the taut position when the knit element is in the stretched position to prevent stretch of the knit element beyond the stretched position.

Catheter for inserting into a hollow organ, in particular a blood vessel, wherein at least one tube- or balloon-like flexural element (12, 12a, . . . , 12l) which can be filled with a filling medium is provided inside the catheter, which flexural element is flexible in the non-pressurized state and stiffens as a result of pressure buildup internally and assumes a predetermined curved shape.
