International Classification:

G01R031/00

US Classification:

324500000

Abstract:

A LED signal lamp that monitors, controls and tests the operational status of a plurality of LEDs. A separate current source is provided for each LED and resistors are in series between the current sources and LEDs. Analog-to-digital converters monitor the voltages at the resistors and LEDs and convert the voltages to digital form for a data processor. The data processor determines the junction temperature of each LED, controls the amount of current supplied to each LED and tests the operational status of each LED by matching its characteristics to a known diode curve. A pulse-width modulator provides further control of the amount of power supplied to the current sources. The data processor further controls a vital disconnect and a vital load. An energy storage/limiter circuit stores energy for the data processor during the absence of normal power input. Related methods of monitoring, controlling and testing such an LED system are also disclosed.

Appl. No.:

13/325645

Inventors:

Terrance P. Fenelon - Mendota Heights MN, US
Thomas Vaughn - Maple Grove MN, US

Assignee:

Mix Manufacturing, Inc. - St. Paul MN

International Classification:

C02F 1/28
B01J 20/26

US Classification:

588255, 252194

Abstract:

A method for solidifying cementitious wastewater by combining the wastewater with a super absorbent polymer composition that includes a UV-stabilizer to form a mixture and disposing of the mixture as solid construction waste. The UV-stabilizer may be a stabilizing additive in the super absorbent polymer composition that inhibits the reversion from a solid or semi-solid mixture back to a liquid. In some embodiments, the method includes placing the mixture in UV-light non-transmissive packaging. After placing the mixture in the UV-light non-transmissive packaging, the package is closed and can be permanently sealed. The sealed package with solidified material therein can then be disposed as solid construction waste. The super absorbent polymer composition can include zeolite or other molecular sieves.
