Embodiments of the present disclosure provide systems and methods for determining temperature profile associated with a thermal storage tank of a hydronic system. The method performed by a control unit includes monitoring a flow rate and a temperature of a volume of hot water and a volume of cold water entering a thermal storage tank via a set of flowmeters and a set of temperature sensors, respectively. The method includes determining a current location of plurality of water layers in the thermal storage tank. The method further includes computing an average temperature value of the at least the hot water and the cold water withdrawn from the thermal storage tank. The method includes generating a temperature profile of the thermal storage tank based at least on the current location, the flow rate and the temperature of the hot water and the cold water, and the average temperature value.

Methods and systems for generating time dependent temperature profile for thermal storage tanks

In a light (optical) beam steering/sampling system, a matrix inversion control technique is used to decouple the operation of the actuators which drive the steering mirrors. The control technique uses two virtual variables, each having an associated independent feedback loop operating in a non-cross-coupled manner, each variable being associated with one of the two steering mirrors.

Optical beam steering and sampling apparatus and method

The present invention is a hybrid cell that utilizes a PBS pair in conjunction with a wedge tuner and a crystal to achieve a more stable interleaver. A first PBS splits an incoming optical signal into two orthogonally polarized beams which follow different optical paths through the cell. The length of the wedge tuner and crystal are selected such that the periodicity of the cell is approximately inversely proportional to the free spectral range at a target frequency. The length of the wedge tuner and crystal are also selected such that there is no change in an optical path difference between the two optical paths with respect to a change in temperature over an operating temperature range.

A thin-film semiconductor pinhole component with monolithically integrated position-sensing photodetectors is herein referred to as a Position Sensitive Pinhole (PSP). Another embodiment is also discussed where a PSP is integrated onto a platform with controllable motion and is herein referred to as a Movable Position Sensitive Pinhole (MPSP). A third embodiment describes the MPSP with capacitive, electrostatic actuation incorporated into the device to achieve controlled motion, herein referred to as a Capacitively Actuated Movable Position Sensitive Pinhole (CAMPSP). Each of those embodiments of the present invention are discussed, as are their method of manufacture and use in a laser environment as a spatial filter.
