A method of manufacturing and a papermaker's or industrial fabric, such as a dryer fabric for the dryer section of a paper machine, includes the application of a polymeric resin material onto preselected locations on the backside of a base substrate using a piezojet array which deposits the polymeric resin material in droplets having an average diameter of 10μ (10 microns) or more to build up discrete, discontinuous deposits of the polymeric resin material having a height of about 0.5 mm at the preselected locations. The preselected locations may be the knuckles formed by the interweaving of the yarns making up the fabric. The purpose of the deposits is to separate the backside of the dryer fabric from a surface, such as that of a dryer cylinder or turning roll, to enable air trapped between the dryer fabric and the surface to escape in lengthwise and crosswise directions parallel to the surface, instead of being forced through the fabric, possibly causing “drop off”. The polymeric resin material is set by means appropriate to its composition, and, optionally, and, if necessary, may be abraded to provide the deposits with a uniform height above the surface plane of the base substrate.

Disclosed is an articulated artificial finger assembly, which can be controlled by the remaining portion of an amputated finger. An adjacent finger is used to manipulate the device when no finger is present. When the stump or adjacent finger begins to bend at the first knuckle, the rest of the device will react to the movements and articulate in the natural manner of a human finger. There are two embodiments shown which, can accommodate a variety of cases. The first embodiment relates to an amputated finger with a portion of the finger remaining. The second is used when a total finger is absent. In either case, the first embodiment uses a ring that is placed over the remaining stub of the finger and the second embodiment a ring is placed over an adjacent finger. The ring, in either embodiment, actuates upper and or lower actuation drives, which are reciprocally and transversely attached to a pivoting block. The pivoting block is fastened to an adjustable middle phalangeal section. The transversely connected upper and lower actuation drives cause the middle phalangeal section to curl under when articulated. The middle phalangeal section is comprised of two main body parts. The first is an outer phalangeal section and the second phalangeal section is placed inside the outer phalangeal section and fastened thereto. A forward fingertip section is pivotally fastened to a forward end of the inner phalangeal section. A forward end of the upper actuating drive is pivotally connected to the forward fingertip section. A supple cover is placed over the device once it is assembled. An inner supple cover is inserted into the device and sealed along the edges of the outer supple cover. To complete the device a screw is inserted into the fingertip, passing through the supple cover and is then hidden by an artificial fingernail placed thereon.

Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

A method activates different interactive functions based on a classification of vibro-acoustic signals resulting from touch events with finger parts of a user. A primary function is trigger when an interactive element on a touch screen is touched with a finger tip of the user. An auxiliary function is launched when the interactive element is touched with a knuckle or fingernail of the user. The touch events result in generating the vibro-acoustic signals. The vibro-acoustic signals are classified and used to distinguish what finger part was used based on the classification of the vibro-acoustic signals.

Apparatuses, processes, and systems for determining features of a paper-making fabric. The apparatus, processes, and systems utilize a representation of a portion of a surface of the fabric, with the representation showing locations and sizes of knuckles and pockets in the surface of the fabric. An image of the portion of the fabric is generated based on the representation. Using the displayed image, an outline is drawn around at least one of the knuckles, and guidelines are drawn such that the guidelines pass through the center of the outlined knuckle, pass through the other knuckles, and form a shape that surrounds areas of the image that correspond to where the pockets are formed between the knuckles. With the outlined knuckle and guidelines, properties that affect the paper-making functionality of the fabric may be calculated.

The bottom machine direction yarns and the bottom cross machine direction yarns of a triple layer fabric are interwoven in a series of repeat units in which the bottom machine direction yarns pass below multiple nonadjacent bottom cross machine direction yarns to form bottom machine direction knuckles, and in which pairs of bottom machine direction yarns separated from one another by one bottom machine direction yarn form bottom machine direction knuckle pairs under a common bottom cross machine direction yarn. Each bottom machine direction knuckle pair forms two imaginary diagonal lines with a nonadjacent bottom machine direction knuckle pair such that each bottom machine direction knuckle pair in the diagonal lines is offset by two cross machine direction yarns and one bottom machine direction yarn.

The arched multi-segmented ramp assembly of the present invention has the advantageous qualities of being portable, lightweight, easily deployable and storable. Identical step links have keystone-shaped sides that abut adjacent members and are joined one to the other by knuckle-like hinges, both of which structural features impart to the unrolled assembly a gently arcuate contour, thereby enhancing the ramp's strength to weight characteristics compared to ramps of the prior art. The hinge connections further permit the ramp to be rolled up for easy transport and storage. Because of its modular design, the arched ramp may be assembled using varying numbers of component step-links, thus providing a user with the flexibility to form a ramp assembly with lengths suitable for different particular applications.

The pivoting knuckle joint for an outdoor lighting fixture comprises a base knuckle, a top knuckle and a fastener for locking the base and top knuckles in position. Each of the base knuckle and top knuckle has a generally cylindrical body with a domed top, a portion of which is cut-away to form a flattened face, and circular cavity formed in the flattened face with a tapered ferrule formed in and extending from the cavity. The ferrule of one of the knuckles has a smaller diameter than the other, so that the smaller ferrule fits within the larger ferrule, forming a pivot point. The relative diameters are adapted to closely fit such that friction is generated between the interfitting ferrules to form a taper lock, resisting rotation of one knuckle relative to the other. In the preferred embodiment, the smaller ferrule has an internal thread formed therein for receiving a locking screw inserted through the body of the knuckle with the larger ferrule, permitting the position of the joint to be locked in place after adjustment. Bores are formed through the base and top knuckles to provide a conduit for an electrical wire to pass through the assembly.

A gravity hinge is disclosed that is simple to manufacture and avoids limitations found in known gravity hinges. The hinge includes two cylindrical knuckles joined by a spindle and separated by a polymer bushing. The junction of the knuckles and the bushing is at an angle oblique to the vertical axis of the knuckles and spindle.
