Abstract: A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment via a receiving section. The rotor blade also includes at least one chord-wise extending pin positioned through the chord-wise joint so as to secure the first and second blade segments together. Further, the chord-wise extending pin includes a hollow cross-section that extends from a trailing edge end to a leading edge end thereof.

Abstract: A span-wise extending pin for joining blade segments of a rotor blade includes a distal portion having a length defined by a first end and an opposing, second end. The distal portion has a conical shape extending for at least a portion of the length thereof for providing ease of insertion of the pin into a pin joint slot of one of the first and second blade segments. The pin also includes a pin portion adjacent to the distal portion. The pin portion includes a first section and a second section. The second section is configured for securing within a beam structure of the first blade segment. The first section extends span-wise from a receiving end of the beam structure. The pin also includes a proximal portion having at least a rod member that extends span-wise through and secures together the pin portion and the distal portion.

Abstract: A rotor blade includes first and second blade segments extending in opposite directions from a chord-wise joint. The first blade segment includes a beam structure that connects with the second blade segment via a receiving section. A chord-wise gap exists between an edge of the beam structure and an edge of the receiving section. The beam structure defines a first pin joint slot, whereas the receiving section defines a second pin joint slot that aligns with the first pin joint slot. First and second bushings are arranged in first ends of the first and second pin joint slots, each having a flange extending within the chord-wise gap. As such, the flanges abut against each other within the chord-wise gap so as to fill the chord-wise gap with a predetermined defined gap or interference. Further, a chord-wise extending pin is positioned through the bushings so as to secure the first and second blade segments together.

Abstract: Embodiments of methods and systems are provided that allow a user to upload inventories, view inventories in the proximity of the user, and/or facilitate transactions over a user device in a simple manner. In an embodiment, a method for transactions comprises loading, by a server at a remote location, an application on a user device of a user, wherein the application allows the user to upload an inventory comprising one or more items and/or services offered for sale by the user, as well as to view on the user device other inventory offered for sale by one or more other users as the user comes into proximity of the one or more other users, and wherein an inventory list maintained at the user device is constantly updated with the other inventory viewed by the user device. The method also comprises receiving, by the server at the remote location, transaction information associated with conducting a transaction in connection with the inventory list over the user device.

Abstract: This invention is a mounting system for a loudspeaker system that is capable of positioning and re-positioning the box-like device of the loudspeaker without requiring the use of any retaining/tensioning fasteners. A bracket facilitates constraining the positioning and repositioning for the roll and pitch axes while simultaneously providing audible feedback angular movement indication that enable vertical and horizontal orientation with respect both to the installation environment and to match its positioning to other like installed systems.

Abstract: A system for poling piezoelectric devices comprises a plurality of thin-film components, a plurality of piezoelectric devices, a poling pad for poling the piezoelectric devices, a plurality of traces, and a plurality of current-limiting elements. The thin-film components are separated by dice lanes to form an array, and the piezoelectric devices are formed on the thin-film components. The traces connect the piezoelectric devices across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric devices, in order to limit current to individual piezoelectric devices that experience current-related failure.

Abstract: A head assembly including one or more transducer elements for controlling head-media spacing is disclosed. The assembly includes detection circuitry configured to receive an input detection signal responsive to the spacing between the head and the data storage media and provide an output measure indicative of the head-media spacing. The output signal is utilized by control circuitry to provide a control input to one of a plurality of transducer elements on the head to protrude a localized portion of the head to adjust head-media spacing.
