Abstract: A rear derailleur assembly for mounting to a bicycle having a frame. The rear derailleur assembly includes an upper body portion configured to operationally engage the rear derailleur assembly to the frame, a controller portion pivotally connected to the upper body, a lower body portion pivotally connected to the upper body and pivotally connected to the controller portion, and a chain cage assembly. The chain cage assembly includes at least two pulleys configured to engage a chain of the bicycle, and a one-piece chain cage configured to retain each pulley at a particular fixed position. Each pulley is rotatable relative to the one-piece chain cage at the particular fixed position of the pulley. The lower body portion is operationally connected to the one-piece chain cage and configured to allow the one-piece chain cage to pivot relative to the lower body portion.

Abstract: A support apparatus for securing a portable electronic device includes a backer plate, a plurality of coupling devices, a power supply tray, a pivotable bracket assembly, a pair of stiffening plates, a pivot axis rod, a locking feature, and a securement strap. The plurality of coupling devices couple to the backer plate and can be coupled to one or more existing structural support elements. The power supply tray secures a stationary power supply electrically coupled to the portable electronic device. The pivotable bracket assembly secures and enables rotation of the portable electronic device. The pivot axis rod pivotally connects to the pivotable bracket assembly, and rigidly connects to the opposing stiffening plates. The locking feature selectively retains the pivotable bracket assembly in an upright vertical position. The securement strap couples the front of the pivotable bracket assembly to the backer plate while securing the top of the portable electronic device.

Abstract: A rear derailleur assembly for mounting to a bicycle, wherein the bicycle includes a frame, includes an upper body for operationally engaging the rear derailleur assembly to the frame. The rear derailleur assembly also include a chain cage for engaging a chain of the bicycle; a controller pivotally connected to the upper body; and a lower body operationally connected to the chain cage, pivotally connected to the controller, and pivotally connected to the chain cage. The lower body includes a damper assembly for providing rotational resistance as the chain cage rotates in a first direction about the pivot axis.

Abstract: A method for extracting at least one audio object from at least two audio input signals, each of which contains the audio object. The second audio input signal is syncronized with the first audio input signal while obtaining a synchronized second audio input signal. The audio object is extracted by applying at least one trained model to the first audio signal and to the synchronized second audio input signal. The audio object is outputted. Further, the step of synchronizing the second audio input signal with the first audio input signal includes the steps of: generating audio signals; analytically calculating a correlation between the audio signals; optimizing the correlation vector; and determining the synchronized second audio input signal using the optimized correlation vector.
