20120060895 | PHOTOVOLTAIC MODULE STRING ARRANGEMENT AND SHADING PROTECTION THEREFOR - A method and apparatus for protecting a string of solar cells from shading in a solar panel having a plurality of strings of solar cells are described. Electric current is shunted around any string of the solar cells having at least one shaded solar cell by shunting the electric current through electrical conductors and a bypass diode located in a perimeter margin of a substrate supporting the solar cells such that no matter which string has a shaded solar cell current through the string with the shaded solar cell is shunted through electrical conductors and a respective bypass diode located in the perimeter margin. This distributes dissipation of heat from respective bypass diodes that are associated with strings having at least one shaded solar cell, to different locations around the perimeter margin. | 03-15-2012 |

20150335984 | ROLLER SKATE BLADE AND SHARPENING THEREOF - A roller mounting apparatus for an in-line roller skate blade comprises a body having a footware connector portion, a spacing portion adjacent the footware connector portion and a roller mounting portion adjacent the spacing portion. The roller mounting portion has roller mounts for mounting a plurality of rollers in tandem spaced apart positions such that contact points on outer surfaces of the rollers will lie on a first common curved line having no portion with a radius of curvature more than about 10 m, so that a contact point on a surface of a roller immediately adjacent to any given roller is spaced apart between about 0.1 mm to about 13 mm from a line tangent to the curved line at a point defined by the contact point of the given roller. A roller blade comprising the roller mounting apparatus is also disclosed. There is also disclosed a method of sharpening an outer circumferential surface of a rotatable roller of a roller blade by causing an outer circumferential surface of a rotating grinding implement to contact the outer circumferential surface of the rotatable roller at a contact point such that a grinder plane containing the contact point and a rotation axis of the rotating grinding implement is disposed at an angle to a roller plane containing the contact point and a rotational axis of the roller. Also disclosed is a method of sharpening an outer circumferential surface of a rotatable roller by causing an outer circumferential surface of a rotating grinding implement to contact the outer circumferential surface of the rotatable roller such that the rotating grinding implement tends to drive the roller in a first direction of rotation while causing a contact surface of a rotating drive wheel to contact the roller to cause the roller to rotate in a second direction against the first direction of rotation to cause relative movement between the roller and the outer circumferential surface of the grinding implement. | 11-26-2015 |

20130200918 | TESTING APPARATUS FOR PHOTOVOLTAIC CELLS - The present invention allows simultaneous measurement of current and voltage produced by a PV cell by removably pressing first and second parallel spaced apart closely adjacent sensing conductors, electrically insulated from each other, onto a current carrying conductor on a front side of the PV cell to make electrical contact therewith, while removably pressing at least one reference contact to a reference conductor on the rear side of the PV cell to make electrical contact therewith. Current is conducted from the current carrying conductor on the front side, through the first sensing conductor to current measuring circuitry and through the at least one reference contact back to the rear side reference conductor. Voltage is sensed at the second sensing conductor relative to the rear side reference conductor, using voltage measuring circuitry. | 08-08-2013 |

20100275976 | PHOTOVOLTAIC MODULE WITH EDGE ACCESS TO PV STRINGS, INTERCONNECTION METHOD, APPARATUS, AND SYSTEM - A photovoltaic module apparatus includes PV cells arranged in a planar array, the PV cells being electrically connected in at least one string having positive and negative terminals. Positive and negative conductors are connected to the positive and negative terminals respectively and front and back encapsulating sheets are disposed on the front and back sides of the array to form a sub-laminate. Each of the positive and negative conductors has a respective portion extending from the positive and negative terminals, between the front and back encapsulating sheets. Front and back protectors are disposed on the front and back encapsulating sheets to form a laminate. First and second terminating portions of the positive and negative conductors extend outwardly from the outer perimeter edge of the laminate. A frame including a frame member having a holder may be provided about at least one portion of the outer perimeter edge of the laminate. | 11-04-2010 |
