Abstract: A dual-mode lubricator with movement-limiting function and potentiometer includes a lower platform structure, upper platform structure fixed on the lower platform structure through multiple support columns, a rotating gear, a driving motor used to drive the rotating gear, a screw member installed in the center of the lower platform structure, the upper platform structure and the rotating gear and connected to the rotating gear and provided with a straight groove, a grease pressing seat connected to the screw member, a movement-limiting member set below the lower platform structure and having a front protrusion, a connector pivotally connected to the screw member, and a potentiometer module with an internal database that stores the data of the corresponding information between the position of the connector and the amount of the remaining grease.

Abstract: An apparatus for estimating a fair value of a SPP includes a sunshine simulation system for generating a peak sun hour; a photovoltaic (PV) yield system for measuring a total power loss rate and generating an estimated energy-production-hours database; and a financial pricing system for generating a series of cash flows and discount factors. The financial pricing system computes a series of present values which are the product of the cash flows and the discount factors, and sums up all the present values to obtain an estimated value of the SPP. Since the apparatus for estimating SPP value takes the real power generation condition of the SPP and the real market economic condition into consideration, so that the apparatus can generate a pricing result even closer to the real market.

Abstract: An automatic grease dispensing monitoring and alarm system using a control unit in each automatic grease dispenser to provide message to a center monitoring control and alarm system wirelessly, achieving wireless remote lubrication control, abnormality alarm, and auto grease-dispensing functions. Each automatic grease dispenser comprises a driving mechanism for driving a piston to dispense the lubricating grease, a microprocessor-based control unit for the setting of the lubricating cycle and for checking the grease dispensing amount subject to the detection of the rate of turn of the driving mechanism through a sensor and a black and white reflective plate.
