20100048038 | MAGNETIC COMPONENT CONNECTOR, CIRCUIT BOARDS FOR USE THEREWITH, AND KITS FOR BUILDING AND DESIGNING CIRCUITS - Printed circuit boards and breadboard devices have contact pads and magnetic component connectors where connection between the contact pads and the magnetic component connectors are made by magnetic force. Either the contact pad or the magnetic component connector will be magnetic and the other will be made of a material to which a magnet will be attracted. For example, printed circuit boards, which usually have copper traces, include contact pads made of a material to which a magnet will be attracted. Circuit components are connected to magnetic component connectors having magnetic legs which then connect the components to the contact pads of the circuit board or breadboard device. This makes the connection of components to a printed circuit board or breadboard device fast and easy and provides for easy removal and replacement of components. Magnetic component connectors can also be configured to connect magnetically to one another. | 02-25-2010 |

20150355040 | ULTRA-SENSITIVE FORCE SENSING BASED ON EVANESCENT LIGHT - Methods, structures, devices and systems are disclosed for implementing a fiber optic force sensing transducer. In one aspect, an exemplary fiber optic force sensing transducer device includes an optical fiber coated by at least one layer of a polyelectrolyte material that utilizes the movement of optical structures coupled to the external polyelectrolyte layer in an evanescent field produced by the optical fiber to detect forces imposing on the fiber. In one aspect, an optical sensing device includes an optical waveguide that internally guides light, one or more layers formed outside the optical waveguide within an evanescent field of the guided light in the optical waveguide, and one or more optical structures coupled to the one or more layers in the evanescent field to emit light based on interaction with the evanescent field to indicate a position of an optical structure relative to an external surface of the optical waveguide. | 12-10-2015 |
