摘要:
The invention provides a system and method for optimizing the cost of buying and price for selling electrical energy by forecasting the price from a plurality of sources of electrical energy for a plurality of time intervals within a set time period, determining an optimum time within the set time period for purchasing or selling electrical energy, and implementing the purchase or sale of electrical energy at the optimum time.
摘要:
A method of making a light controlling window covering includes making a plurality of cells. Each cell desirably includes a substantially opaque top strip having a front edge and rear edge, a substantially opaque bottom strip opposing the substantially opaque top strip, the bottom strip having a front edge and a rear edge, and a front shear strip extending vertically between the top and bottom substantially opaque strips at a front of the cell. Each cell also desirably includes a rear strip extending vertically between the top and bottom substantially opaque strips at a rear of the cell, and using an adhesive material for connecting ends of the front and rear shear strips to ends of the top and bottom opaque strips to form a generally rectangular-shaped loop.
