  • Publication number: 20260227153
    Abstract: A target dot sight includes a target illumination sensor that senses the amount of illumination at a target, rather than merely sensing the ambient sight of the entire operating environment. Then, based on the sensed target illumination, the target dot sight may automatically compensate for the brightness of the target.

  • Patent number: 10946188
    Abstract: A method and apparatus for the concurrent treatment of multiple oral diseases and defects while promoting general oral hygiene utilizing direct current electricity and methods for manufacturing the same. Electrodes are used to deliver a direct current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.

  • Patent number: 9588148
    Abstract: A transformer for monitoring current in a power cable is magnetically linked with the power cable connected to the electrical device, where the transformer produces a changing transformer signal in response to the presence of a changing current within the power cable. An input circuit located proximate to the transformer and having an output terminal and being electrically connected to the transformer so as to receive the changing transformer signal. The input circuit produces, in response to receiving the changing transformer signal, one of a first signal representative of the changing current, and a first circuit condition at the output terminal of the input circuit representative of the changing current in the power cable. The input circuit includes an impedance set having an effective impedance that comprises a plurality of elements, wherein at least one of the elements is not electrically connected to the remaining the plurality of elements.

  • Patent number: 9568309
    Abstract: A pedal assembly for a velocipede is provided. The pedal assembly includes an axle, pedal body, a first drive pin and a first actuator. The axle includes a distal end and a proximal end. The axle defines a first cam groove. The proximal end is configured for releasable attachment to a crankshaft. The pedal body is rotatably coupled with the axle and is rotatable with respect to the axle about an axis. The axis resides in an imaginary plane. The first drive pin is movably coupled with the pedal and is movable between an inserted position and a withdrawn position. The first actuator is movably attached to the pedal body and is associated with the first drive pin. The first actuator is movable between a first position and a second position. An apparatus for determining a pedal configuration for a user is also provided.
