Abstract: A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

Abstract: A bicycle front shifting system includes operable to transmit a wireless signal, a crank assembly with two crank arms and a pedal on each of the two crank arms. The crank assembly is rotatable about a rotation axis. A front shift unit is coupled to the crank assembly and is rotatable about the rotation axis. The front shift unit includes a chain ring component with a big chain ring and a small chain ring. The small chain ring has a small diameter and the big chain ring has a big diameter that is larger than the small diameter. A shift mechanism is coupled to and rotatable with the chain ring component about the rotation axis. The shift mechanism is configured to receive the wireless signal from the shifter and to shift a chain between the big chain ring and the small chain ring according to the wireless signal.

Abstract: Systems and methods of adaptive workflow definition of crowd sourced tasks and quality control mechanisms for multiple business applications are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for generating and distributing tasks to workers to optimize product categorization in an online marketplace, generating and distributing tasks to workers for search engine optimization of a website, and/or generating and distributing tasks to workers for business data verification and enhancement. Results can be aggregated from multiple workers to enhance or improve site information, site organization, or other business information to improve site placement in search results and/or to enhance/improve user experience.

Abstract: A rack for animal cages may comprise multiple levels stacked together in a vertical orientation, each level acts as a frame configured to support one or more tubs that serve as cages. An example rack for animal cages comprises a first enclosure, a first top panel, and two glides. The first enclosure having a floor, four exterior sidewalls, and a lip extending outwardly from a top surface of at least two of the four exterior sidewalls. Each of the two glides comprises a first longitudinal groove configured to receive an edge portion of the first top panel therein and a second longitudinal groove configured to removably receive a portion of the lip extending outwardly from the top surface of the first enclosure. The two glides are positioned to support the first top panel and the first enclosure therebetween, and configured to position the first top panel so that it covers the first enclosure when it is positioned therebetween.

Abstract: Implementations of a rack for animal cages are provided. A rack may be comprised of multiple levels stacked together in a vertical orientation. In some implementations, each level of the rack acts as a frame configured to support thereon one or more tubs (i.e., cages). In some implementations, each level of the rack may be comprised of top panels, glides, joint connectors, vertically oriented legs, and cross beams. In some implementations, two glides may be positioned on a level of the rack to support a top panel and tub therebetween. In this way, the glides hold the top panel in position over the tub and thereby prevent an animal from escaping the interior compartment(s) of the tub. In some implementations, a level may be further comprised of a bracket having a lip thereon. In some implementations, the bracket may be used to reinforce the unsupported edges of the top panel.

Abstract: The subject matter of this specification can be embodied in, among other things, a process control valve including a fluid valve body having an inlet for receiving fluid, an outlet for discharging fluid, a fluid flow passage connecting the inlet and outlet, and a controllable throttling element which is moveable to selectively vary the cross-sectional area of flow of at least a portion of the passage, a valve actuator coupled to the valve body and responsive to control signals, a sensor for producing at least one signal representative of at least one of absolute pressure, gage pressure, differential pressure, flow, and temperature within the fluid flow passage, a communication system for receiving configuration information and transmitting status information, and a controller comprising a processor for receiving said signal and configuration information, for developing an output dependent upon the configuration information and the received signal, and for developing the status information.
