International Classification:

G08B 1/08

US Classification:

3405391

Abstract:

Systems and methods for monitoring the condition of equipment in a manufacturing plant or other facility. A computing node is attached to each piece of equipment under consideration. Each node gathers relevant information from the machine using sensors and is capable of determining the condition of the machine from a preexisting set of possible conditions, using only the information obtained from the sensors. Each node is thus entirely self-sufficient, in that it requires no interaction with a global controller or with other nodes in order to make a decision about the condition of the equipment, and does not necessarily require any information about the past history of the equipment. The nodes are capable of communicating the condition of their corresponding equipment to key maintenance or other personnel, potentially via a wireless network to a convenient wireless-capable device such as a cellular phone or laptop.

International Classification:

H05B 41/16
F21S 4/00

US Classification:

315250, 36231101, 36231102

Abstract:

A lamp that produces an infinitely variable range of time, space, and color patterns. The lamp includes a plurality of colored light sources that produce light in at least two different visual spectrums, a single modulation device that generates a modulation scheme for each of the plurality of light sources, a display screen, and a mask that masks off at least a portion of light illuminating the display screen. The generated modulation scheme is produced at a predefined intensity level. A controller selectively alters delivery of the modulation scheme to each of the plurality of light sources. A first switch allows a user to select one of a plurality of modulation schemes. A second switch allows a user to alter the predefined intensity level. A third switch allows a user to select one of a plurality of modulation rates.

International Classification:

G01J 5/00
G01R 31/265

Abstract:

Dynamic Digital Modulation obtains thermal image data on active semiconductor devices with sufficient sensitivity to be used in situ with packaged devices. These techniques can be applied to dynamic failures, but can also produce quantitative data of actual power dissipation as the device is placed into different operational modes. The thermal image results can be analyzed to assist in thermal management and assessing reliability and failure analysis issues in semiconductor devices.
