  • Patent number: 10711869
    Abstract: Traction planets and traction rings can be operationally coupled to a planetary gearset to provide a continuously variable transmission (CVT). The CVT can be used in a bicycle. In one embodiment, the CVT is mounted on the frame of the bicycle at a location forward of the rear wheel hub of the bicycle. In one embodiment, the CVT is mounted on and supported by members of the bicycle frame such that the CVT is coaxial with the crankshaft of the bicycle. The crankshaft is configured to drive elements of the planetary gearset, which are configured to operationally drive the traction rings and the traction planets. Inventive component and subassemblies for such a CVT are disclosed. A shifting mechanism includes a plurality of pivot arms arranged to pivot about the centers of the traction planets as a shift pin hub moves axially.

  • Patent number: 10598528
    Abstract: An apparatus includes a tube, first and second pairs of electrodes, a reference device, and a processor. The processor determines a speed of a fluid traveling between the first and second pairs of electrodes and determines a reference conductance of the fluid using the reference device. The processor also determines a measured conductance of the fluid using at least one of the first and second pairs of electrodes and determines, based on the reference conductance and the measured conductance, a cross-sectional area of the fluid at an electrode. The processor further adds a correction factor to the determined speed to produce a bulk speed of the fluid. The processor further determines a volumetric flow rate of the fluid based on the bulk speed and the determined area and determines a volume of the fluid based on the determined volumetric flow rate.

  • Publication number: 20190195321
    Abstract: A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed.

  • Patent number: 10185911
    Abstract: A radio frequency identifier (RFID) tag is provided for receiving and reflecting electromagnetic energy at select frequency bands of visible and infrared wavelengths. The RFID tag includes an electrically conductive backplane; a dielectric substrate disposed on the backplane; a light guide film (LGF) disposed on the substrate, and metamaterial elements. The LGF has an exposed surface segregated into domains. The metamaterial devices are disposed on a domain. Each device is tuned to respond to a corresponding frequency among the select frequency bands.

  • Publication number: 20180203189
    Abstract: A light transmission system is provided for operating an optically responsive circuit. The system includes a light guide film (LGF) to transmit light emitted from its edge, and a scattering node for directing the light to the circuit. The circuit is disposed on a proximate face of the LGF. The scattering node is disposed on a distal face of the LGF opposite the circuit. The circuit can be an integrated circuit, a light detection sensor or a photovoltaic cell.

  • Patent number: 6066374
    Abstract: A transparent, light resistant container is provided for storage of medicinal agents, such as tablets, capsules, and the like. In broad terms, the container includes a container body having self-sustaining wall structure of predetermined thickness formed from a synthetic resin composition. A quantity of a coloring agent dispersed in the resin composition. The quantity of the coloring agent is correlated with the thickness of the wall structure to permit transmission through the wall structure of no more than 10% of light having a wavelength of between about 400 nm to 450 nm while permitting transmission through the wall structure of adequate visible light to allow external visual inspection of printed characters on solid medicinal tablets and capsules stored in the container. In addition, an amount of a UV absorber is dispersed in the resin composition.
