A method of fracturing using deformable proppants minimizes proppant pack damage, without compromising the fracturing fluid's proppant transport properties during pumping, by use of deformable proppants. Selection of proppant is dependent upon the mechanical properties of the formation rock. The strength of the deformable proppant is dependent upon the modulus of the formation rock being treated such that the proppant is capable of providing, at the very least, a minimum level of conductivity in in-situ stress environments. The maximum elastic modulus of the deformable proppant is less than the minimum modulus of the formation rock which is being treated. The method is particularly applicable in fracturing operations of subterranean reservoirs such as those comprised primarily of coal, chalk, limestone, dolomite, shale, siltstone, diatomite, etc.

An electronic device interface is provided that is selectively interconnectable to a portable electronic device. The interface is preferably interconnected to the portable electronic device via inwardly-biased arms that end in fingers that engage opposing edges or corners of the portable electronic device. The interface may receive a positioning grip that includes a support having at least one selectively deflectable surface.

A positioning grip or device is provided that is selectively interconnectable to a portable electronic device. The positioning grip is preferably interconnected to the portable electronic device via a mechanism that provides a suction cup and allows for selective rotation of the portable electronic device. The positioning grip also includes a support having at least one selectively deflectable arm.

A system and method for maintaining positions of bones fixed or approximated relative to each other is provided that is ideal for minimizing interference with surrounding viscera in spinal column procedures, although other good application therefor are also disclosed. In the preferred form, a cable anchoring apparatus in the form of a screw member having an elongate shank that is threaded for substantially the full length thereof is employed. An internal driver surface is provided so that the size of the proximate end of the shank can be minimized or maintained consistently sized with respect to the reminder of the shank with no enlarged driver head formed thereat. This allows the amount of bone material that is removed from full insertion of the screw anchor to be minimized, i.e. no countersinking for an enlarged driver head is necessary, thus improving holding power of the cable anchor herein. Further, the full threading of the shank for substantially its entire length enables the screw member to be fully sunk into the bone so that no portions thereof, such as an enlarged screw head, project into the surrounding body cavity in which the bone is located. In the spinal column application, a criss-cross cable pattern is disclosed to better resist torsional forces and keep any decompression devices in place in the gap between adjacent vertebrae.

The aim of the invention is to provide a fluid-cooled electric machine in a simple manner. To achieve this, a housing (1) is configured in two parts, in such a way that each housing part (2, 3) comprises a bearing bracket (4, 5) and said housing parts are designed (2, 3) to form cooling channels once assembled.

The invention relates to a protecting apparatus (10) for protecting a structure (100) from an impact. The protecting apparatus (10) is arranged to be mounted on the structure (100) and includes a bumper member (12), a structure positioning member (14) and at least one resiliently flexible joining portion (16). The structure positioning member (14) is arranged in use to be positioned in contact with or adjacent to a portion of the structure (100) being protected. The at least one resiliently flexible joining portion (16) extends between the bumper member (12) and the structure positioning member (14) so that when an outer surface (12a) of the bumper member (12) is impacted, the impact force is dissipated at least in part by flexure of the at least one joining portion (16).

A headgear for securing a patient airway interface device to a patient's head, and in particular an infant patient. The headgear includes a central body, first and second forehead straps, and first and second lower straps. The forehead straps extend from opposite side of the central body. The lower straps also extend from opposite sides of the central body, and are inferiorly spaced from a corresponding forehead strap. Upon application to a patient's head, the central body and the forehead straps establish a line of attachment extending from the patient's forehead to a nape of the patient's neck (i.e., adjacent the occipital bone). The lower straps are then available for connecting an airway interface piece to the headgear.

A capacity designating unit designates a capacity, which a user desires, of virtual disks provided to a disk pool. A first selecting unit selects one (1) or a plurality of physical disks that satisfy the designated capacity from a disk pool that registers the physical disks such that the number of the selected physical disks is minimized, and assigns the selected physical disks to the virtual disks. A second selecting unit selects one (1) or a plurality of physical disks that satisfy the designated capacity such that the number of extents that is the number of areas that are scattered in the physical disk and are not assigned is minimized, and assigns the selected physical disks when the selection by the first selecting unit is unsuccessful.

A telescoping downdraft ventilator with a movable fan and efficient way of removing gases and fumes is disclosed. The telescoping downdraft ventilator has the ability to fit behind a cook top unit beneath a countertop when the cook top unit is located against a wall. The telescoping downdraft ventilator has a fan that may be attached in front of the unit or behind the unit. The ventilator collects and draws in exhaust fumes and smoke, filters it, and re-circulates or expels it through a movable exhaust duct.

A paper making composite forming fabric including paper side weft and warp yarns and wear side warp yarns and bindery yarns. The paper side wefts and the binder yarns being interwoven with the paper side warp yarns. The binder yarns being interwoven with the wear side warps. A total number of paper side and wear side warp yarns per weave repeat is greater than 24. An internal binder float length is between 2 and 4. The fabric has an interchange points percentage value of less than 20 and a binder interchange points as a percentage of total machine direction yarns value of less than 10.

The invention provides a variety of devices for supporting at least a portion of a user's body. In some embodiments, the invention provides a support device which includes a bladder capable of containing a fluid and a post adjacent the bladder. The bladder may form a rolling diaphragm portion with the post such that when a force is applied to the bladder, the rolling diaphragm portion of the bladder rolls along the post decreasing the volume of the bladder. In some embodiments, the invention provides a post which includes a reduced cross-sectional area in comparison to an adjacent region of the post such that the resistance of the rolling diaphragm portion of the bladder to rolling movement along the post due to the applies force decreases as the bladder rolls along the reduced cross-sectional area region. In some embodiments, the support device includes a plurality of bladders and / or a plurality of posts.
