- Inventor(s):
- Steven Ruggiero, Carol Tanner
- Patent Number:
- US 8456635 B2
- Description:
Example methods and apparatus for obtaining suspended particle information are disclosed. A disclosed example method includes emitting light from a light source, dividing the light source into a first path and a second path, and directing the first path to a first container comprising a plurality of particles in a suspension material. The example method also includes directing the second path to a second container containing a suspension material devoid of particles, retrieving a first transm…

- Description
- Example methods and apparatus for obtaining suspended particle information are disclosed. A disclosed example method includes emitting light from a light source, dividing the light source into a first path and a second path, and directing the first path to a first container comprising a plurality of particles in a suspension material. The example method also includes directing the second path to a second container containing a suspension material devoid of particles, retrieving a first transmission value of the first path through the first container, and retrieving a second transmission value of the second path through the second container. The example method further includes directing the first and second paths to the second and first containers, respectively, retrieving a third transmission value of the first path through the second container, retrieving a fourth transmission value of the second path through the first container, and calculating a ratio of the first and second transmission values to the third and fourth transmission values to determine an indication of transmissivity for a given wavelength.

- Patent Number:
- US 6445869 B2
- Description:
A sealed fiber-optic bundle feedthrough by which a multitude of fiber-optic elements may be passed through an opening or port in a wall or structure separating two environments at different pressures or temperatures while maintaining the desired pressure or temperature in each environment. The feedthrough comprises a rigid sleeve of suitable material, a bundle of individual optical fibers, and a resin-based sealing material that bonds the individual optical fibers to each other and to the rig…

- Description:
An electrical lock mechanism includes a series of sequentially connected memory storage elements, such as flip-flops, terminating in one or more electrical and/or electromechanical devices that control an external function. Entries into the circuit are made from a plurality of remote switches or switching devices connected to interlocks or logic elements, such as nand gates, that are connected between adjacent memory storage elements. Entry to the circuit through the interlocks in a single pr…

- Description
- An electrical lock mechanism includes a series of sequentially connected memory storage elements, such as flip-flops, terminating in one or more electrical and/or electromechanical devices that control an external function. Entries into the circuit are made from a plurality of remote switches or switching devices connected to interlocks or logic elements, such as nand gates, that are connected between adjacent memory storage elements. Entry to the circuit through the interlocks in a single predetermined sequence allows for the setting of successive memory elements; the memory elements serve to nullify any progress through the sequence if an incorrect entry is made. An exchangeable code module between the switches and the circuit allows for the changing of switch combinations. The predetermined code may require the correct selection of single switches in a particular sequence, as well as simultaneous entries from a plurality of switches. Several circuits may be connected in series, such that a plurality of individuals having knowledge of their respective portion of the sequence are required to effect the proper combinations. A simple circuit allows for about 50,000 possible combinations, and several million possible combinations may be easily attained.
