Abstract:
In one aspect of the present invention, a photovoltaic module includes a plurality of sub-modules. Each sub-module includes a plurality of photovoltaic cells spatially arranged as an array, each cell having first and second conductive layers sandwiching an active layer therebetween. The cells in each sub-module are electrically connected to each other in series. Each sub-module further includes positive and negative electrodes formed on the second conductive layers of the first and last cells, respectively, in a respective sub-module. The positive electrode of each sub-module is electrically connected to each other and the negative electrode of each sub-module is electrically connected to each other such that the plurality of sub-modules is electrically connected in parallel. The plurality of sub-modules is spatially arranged next to each other as an array such that at least one sub-module is spatially separated from its immediately next sub-module by a gap.
Abstract:
A feed roller assembly including an axle, a feed roller fixedly mounted around the axle and turned with it to feed a sheet of paper forward, an end cap fixedly mounted on one end of the axle and having a projecting rod raised from an inner side, the projecting rod having a bevel face, and a transmission gear turned about one end of the axle adjacent to the end cap, the transmission gear having a springy projecting rod raised from one end and moved to act against the projecting rod of the end cap, causing the end cap and the axle to be turned with the transmission gear, the springy projecting rod of the transmission gear passing over the bevel face of the projecting rod of the end cap when the roller is pulled by a transmission roller, which delivers the fed sheet of paper forwards, to turn the axle and the end cap at a higher speed than the transmission gear, permitting the end cap and the axle to be turned relative to the transmission gear.
Abstract:
The present disclosure provides an active warning device for server and the warning method thereof. The active warning device is applied to a server. When a control module in the server is departing from a midplane board, the active warning device can provide warning actively. Thereby, a user can notice that the control module is been drawing out of the server and then uses his both hands to support it for preventing tilt, fall, and hence damage of the control module.
