Pedicle screws are secured in two columns, one along each side of the spine. Cross support rods have ends connected to pedicle screw heads. A longitudinally extending rod is supported on the cross supports and recessed in the cavity created by removal of portions of spinous processes, providing a reduced profile of the installed construct. Several types of cross supports are shown such as: arms from the screws inward to rings or yokes connecting the longitudinal rod; cross rods with ends connected to the screws and having centrally-located yokes for the longitudinal rod; cross rods with articulating longitudinal rod portions fixed or swiveled to them. These cross rods may have end portions angled posterior toward anterior to accommodate lateral positioned pedicle screws, but shorter cross rods without angled end portions enable medialized pedicle screw orientation.

A percussive massager is provided having a housing supporting a motor having an output shaft rotatably driven thereby. At least one positioning member is movably connected to a percussion arm which is attached to the housing and operably connected to the motor output shaft. At least two massage nodes are operably connected to the percussion arm, one of which being attached to the positioning member, to form a massage surface and move toward and away from the housing to provide a percussive massage effect. A rotary mechanism is rotatable with respect to the percussion arm and drives the positioning member toward and away from a central region of the housing. An ancillary transmission has an output and an input for operably imparting rotation to the rotary mechanism such that the spacing of the massage nodes progressively increases and decreases.

A backpack structure combined with pull-carrier device, which is provided with transformation spaces for retaining articles, and achieves multifunctionality that enables a person to carry the backpack on the back, the shoulders or by hand. The backpack is mainly structured from a basic bag, different sides of which are connected to transformation portions, which enable transformation of the basic bag to form various expanded or contracted states, and thereby providing a carrying device with functionality to achieve flexible adjustment of internal capacity. In addition, a pull-carrier device is movably fitted juxtaposed to a back carrying side of the body of the basic bag configured with straps. Furthermore, when using the straps to carry the backpack on the back, the pull-carrier device will not cause uncomfortableness in the back of a user, and a wheel portion of the pull-carrier device will not soil the back of the user.

A modular footwear display system includes a display module having a display surface for supporting an item of footwear and a divider for identifying boxed footwear associated with the displayed item of footwear. The display module has at least one mounting fixture for slidably suspending the display surface from a track. A plurality of display modules may be provided in a cabinet and adjusted to accommodate varying quantities of boxed footwear for efficient use of retail space.

The invention relates to a movable fastening unit for a seat frame in an aircraft. In said fastening unit, a connecting element can be movably mounted on both a seat structure and a floor fixture by means of bearings, thus allowing the seat frame to be moved relative to the floor fixture without having to detach the fixture from the floor.

One or more embodiments of a thumbnail caching system dynamically provide a thumbnail cache of digital content items (e.g., photos, videos, audio) to a user on a client device. In particular, the thumbnail caching system provides a thumbnail cache of a digital content collection to a client device such that the thumbnail cache does not exceed a threshold storage limit for the client device. In addition, the thumbnail caching system intelligently adjusts the thumbnails within the thumbnail cache to keep the size of the thumbnail cache within the threshold storage limit irrespective of the number of digital content items stored or added to the digital content collection. Further, the thumbnail caching system can dynamically adjust the size of the thumbnail cache in response to a user adding or removing external data to the client device.

Systems for providing support within the pelvic region of a patient. The systems can include an elongated incontinence sling having a central support portion adapted to be positioned to support any one of the urethra or anus, and a sling tension adjustment mechanism operatively attached to the elongated sling. The sling tension adjustment mechanism can include a plunger device adapted for traversal within an interior of the housing, and an inflatable bladder provided within the housing to selectively control traversal of the plunger. Alternatively, the adjustment mechanism can include a bobbin device within the housing and one or more retention devices to selectively restrict unwinding of a suture from the bobbin device.

The invention provides an LED multi-segment type outdoor emergency lighting lamp. The LED multi-segment type outdoor emergency lighting lamp comprises a lighting layer, a power supply layer, a storagelayer, an inflation layer, a disposable popup type cloth bag, a combined power supply interface, a waterproof rubber sliding cover, an outer electrode, a buckle connecting belt, an external connection type solar charging base and metal conductive buckles. The metal conductive buckles are arranged at the top end and the bottom end of the lighting layer. The bottom end of the lighting layer is connected with the power supply layer through the metal conductive buckle. The metal conductive buckles are arranged at the top end and the bottom end of the power supply layer. The bottom end of the power supply layer is connected with the storage layer through the metal conductive buckle. The bottom end of the storage layer is in buckle connection with the inflation layer. The disposable popup typecloth bag is arranged at the bottom end of the inflation layer, and the combined power supply interface is arranged on the side face of a power supply layer shell. Through the arrangement of a lamp opening fluorescent layer, the problems that after a power source of an existing outdoor LED lighting lamp is used up under the severe situation, a certain lighting means cannot be provided, and other survival auxiliary functions are limited are solved.

The invention belongs to the technical field of polymer preparation, and particularly relates to a preparation method of a thermoplastic polyurethane elastomer. The method comprises the following steps: S1, melting polymer polyester diol (PES), equivalently adding the molten PES into two material tanks A, carrying out heating to a required material temperature of 100-120 DEG C, removing vacuum, and introducing nitrogen for later use; S2, melting diisocyanate (MDI), equivalently adding molten MDI into the two reaction kettles, carrying out heating to 45-52 DEG C in a water-bath flowing manner,carrying out vacuum degassing for 30-45 minutes under low-speed stirring, removing vacuum, and introducing nitrogen for later use, wherein diisocyanate in the reaction kettles is heated in the water bath flowing heating manner, so the vacuum degassing efficiency of the heated diisocyanate is improved; and S3, conveying stock solutions prepared in the steps S1 and S2 and various solvents to a pouring head, carrying out uniform primary mixing under high-speed stirring, conveying the obtained mixture to a double-screw reaction extruder, carrying out further uniform mixing and a chemical reaction,and carrying out granulation and screening to prepare the thermoplastic polyurethane elastomer.
