An apparatus for monitoring and controlling a haze and/or particulate level in the air is disclosed. The apparatus comprises a detecting unit (sensor) and a controller. The detecting unit is configured to detect the haze and/or particulate level in real time. The controller in communication with the detecting unit is configured to receive data related to a haze level from the detecting unit. The apparatus further comprises a display and a control switch. The display in communication with the controller is configured to display data related to the haze level monitored by one or more sensors. The sensors are laser based particulate sensors. The control switch in communication with the controller is configured to send a signal to control a haze generator, thereby monitoring the haze level in real time and controlling the haze generator at predetermined time periods using the control switch for attaining and maintaining a desired haze level.

An isolation device for supplying a workspace with clean air resulting from dust filtration by an air cleaning means accurately manages the number of fine particles in a workspace and prevents fine particles from mixing with an experimental material. The isolation device includes a measurement probe; a particle counter for measuring the fine-particle counts for a plurality of particle sizes in the workspace air and outputting the measurements; a storage unit for storing, for each of the plurality of particle sizes and for work times and non-work times, management fine-particle counts at which the number of fine particles per unit volume is determined to be large; a cleanliness determination unit that compares the fine particle counts and the management fine-particle counts; and an output unit for outputting an alarm when the work-time/non-work time fine particle count for a particle size in the workspace exceeds the corresponding management fine-particle count.

A method includes performing a downhole operation in a borehole; capturing, during the downhole operation, downhole particles and drilling mud at the surface from the borehole into a screen of at least one shaker; shaking the screen to emit vibrations to separate the downhole particles from the drilling mud; defining a vibration limit for a normal operating condition of the at least one shaker; setting a vibration fault threshold based on the vibration limit for the normal operating condition; monitoring, using at least one sensor, the vibrations over time; and determining there is a fault condition for the shaker, in response to the vibrations exceeding the vibration fault threshold.

Device for improving an optical detecting smoke apparatus and implementing thereof. Apparatus and methods for detecting the presence of smoke in a small, long-lasting smoke detector are disclosed. Specifically, the present disclosure shows how to build one or more optimized blocking members in a smoke detector to augment signal to noise ratio. This is performed while keeping the reflections from the housing structure to a very low value while satisfying all the other peripheral needs of fast response to smoke and preventing ambient light. This allows very small measurements of light scattering of the smoke particles to be reliable in a device resistant to the negative effects of dust. In particular, geometrical optical elements, e.g., cap and optical defection elements, are disclosed.

Manual and automatic methods and devices using a ACOMP system for active control of polymerization reaction processes. An ideal desired trajectory of one or more reaction and polymer characteristics can be established to produce a desired final polymer product with specified characteristics from a polymerization reaction process. A current reaction trajectory of a polymerization reaction process can be driven to an ideal or desired reaction trajectory. In a manual embodiment an operator can use ACOMP data to adjust process variables in order to drive the current reaction trajectory toward the ideal or desired reaction trajectory. In an automated mode a control program can use ACOMP data to make adjustments to process variables to drive the polymerization reaction process toward the desired trajectory as closely as possible either empirically or by solving the governing equations for the polymerization reaction process.
