Abstract:
A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

ABSTRACT OF THE DISCLOSURE A self-leveling caster assembly includes a caster frame and a castor fork which is configured to pivot relative to the caster frame. A spring or other biasing mechanism biases the caster fork away from the caster frame, to maintain contact between the ground and a wheel supported by the caster fork along a travel range of the wheel. Even if a frame supporting the self-leveling caster assembly is bent, pulling the wheel away from the ground, the biased caster fork will maintain contact between the ground and the wheel, allowing continued use of a shopping cart or other wheeled apparatus including the self-leveling caster assembly.

Abstract:
An embodiment of a light powered transmitter (100) configured for broadcasting an electromagnetic control field to a region is provided. The transmitter comprises a housing (110) having a longitudinal axis. The housing comprises a photovoltaic cell configured to generate electrical power in response to light and a rechargeable power source configured to store at least a portion of the power generated by the photovoltaic cell. The housing also comprises an electromagnetic transmitter and a directional antenna. The directional antenna can be configured to broadcast an electromagnetic (e.g., radio-frequency) control field to a region. The directional antenna can be rotatably mounted in the housing such that the antenna can be rotated around the longitudinal axis. The housing can further comprise a transparent or translucent optical element (120) configured to receive the light and converge at least a portion of the light onto the photovoltaic cell.
Abstract:
Una rueda para un carro de propulsión humana, en que la rueda comprende: un conjunto de alojamiento (70) que comprende un buje (80) y una cubierta (90), teniendo el buje (80) una cavidad interior y comprendiendo una superficie de encaje con cuadro que tiene un primer elemento conjugado (82), estando configurada la cavidad interior para recibir un componente eléctrico, y en que el primer elemento conjugado (82) es recibido en un primer rebajo de banda de rodadura (25) de un cuadro (20) y comprende una brida (84) que se extiende radialmente hacia fuera; la cubierta (90) configurada para ser cerrada por junta con el buje (80), inhibiendo con ello el acceso hacia dentro de la cavidad interior; un conjunto de banda de rodadura (10) configurado para recibir axialmente una parte del conjunto de alojamiento (70), comprendiendo el conjunto de banda de rodadura (10) el cuadro (20) y una banda de rodadura (60), comprendiendo el cuadro (20) una superficie de encaje con banda de rodadura y una superficie de encaje con buje, teniendo la superficie de encaje con buje un segundo elemento conjugado (22) y estando configurada para acoplarse de forma separable con la superficie de encaje con cuadro del buje (80), y en que el segundo elemento conjugado (22) es recibido dentro de un primer rebajo de alojamiento (85) del buje (80) y comprende una brida (24) que se extiende radialmente hacia dentro; la banda de rodadura (60) dispuesta radialmente hacia fuera del cuadro (20), estando configurada la banda de rodadura (60) para acoplarse a una superficie sobre la cual la rueda está configurada para rodar; y una sujeción configurada para encajar axialmente el primer elemento conjugado (82) de la superficie de encaje con cuadro y el segundo elemento conjugado (22) de la superficie de encaje con buje; en que el conjunto de banda de rodadura (10) está configurado para acoplarse de forma separable con el conjunto de alojamiento (70) de tal modo que el conjunto de banda de rodadura (10) puede ser separado axialmente del conjunto de alojamiento (70) sin eliminar la junta entre la cubierta (90) y el buje (80), facilitando con ello la reparación o la sustitución del conjunto de banda de rodadura (10) al tiempo que se mantiene la junta entre la cubierta (90) y el buje (80), y en que, cuando la superficie de encaje con buje del cuadro (20) está acoplada a la superficie de encaje con cuadro del buje (80), el primer elemento conjugado (82) y el segundo elemento conjugado (22) están alineados circunferencialmente de tal modo que la sujeción puede encajar axialmente el primer elemento conjugado (82) y el segundo elemento conjugado (22).
Abstract:
Various loop antenna fixture embodiments are disclosed. The fixture can be configured to removably attach with other fixtures, thus changing the overall dimensions of an antenna wrapped around the periphery of the fixture or fixtures. Advantageously, after the antenna is wrapped around the fixture(s) to form an assembly, the entire assembly can be removed and installed without the requirement of removing the antenna from the fixture(s).
