Abstract: An improved sub-structural roof construction component which provides support for exterior building metal roofing materials, which allows for standard components designed and manufactured in factory to be installed at jobsite, and which can accommodate variations required in the field. These framing components can be adjusted in field for height and can be rotated to fit the customer's roof design slope.

Abstract: Disclosed herein is a device, system, and method for a trickle charging system of non-inductive voltage boost (NVB) converter with built-in auto-dummy-load (ADL) for wide-range of charge storage devices i.e. small button-cell type batteries and super-caps using micro power pyro-electricity at Si-MOS sub-threshold voltage. A VLSI configuration of the system is also disclosed in embodiments. The system converts the pyro-electric material at MOS sub-threshold 0.37V for optimizing to the battery charging level at 1.45V. This system was proven at hardware level and found to be 98.8% power efficient. The designed IC can charge independently without any external components for up to 1 uW max, but able to charge up to 20 uA with external components. Thus it is considered to be a very versatile design.

Abstract: Disclosed herein is a non-Inductive voltage boost-converter (NVBC) for micro-power energy harvesting systems for energy storage and delivery applications. Current devices deliver a wide-range of micro-power having only up to 0.8V peak-voltage, but nominally 0.45V in lab test conditions. This voltage is not adequate in charging storage cells such as rechargeable batteries and also driving electronic circuits. Technology is in demand where a boost-converter must operate at MOS sub-threshold voltage (Sub-VTH) limits. Disclosed herein is a novel NVBC device that has eliminated the need of an inductor coil and associated high-speed switching circuits; thus achieving higher efficiency. The disclosed invention applies a simple self-synchronizing technique to adapt the NVBC automatically to the low-frequency energy signal of a pyroelectric device. A novel NVBC is presented for stabilized output of NVBC (S-NVBC). In an embodiment, the S-NVBC achieves an efficiency of 86%.
