Filter with memory, communication and concentration sensor

Abstract

The present invention describes a system and method for accurately measuring the concentration of a substance within a filter housing. A concentration sensor and a communications device are coupled so as to be able to measure and transmit the concentration of a particular substance within the filter housing while in use. This system can comprise a single component, integrating both the communication device and the concentration sensor. Alternatively, the system can comprise separate sensor and transmitter components, in communication with one another. In yet another embodiment, a storage element can be added to the system, thereby allowing the device to store a set of concentration values. The use of this device is beneficial to many applications. For example, the ability to read concentration values in situ allows integrity tests to be performed without additional equipment.

Description

BACKGROUND OF THE INVENTION [0001] The use of wireless communication has become prevalent, especially in the management of assets, particularly those applications associated with inventory management. For example, the use of RFID tags permits the monitoring of the production line and the movement of assets or components through the supply chain. [0002] To further illustrate this concept, a manufacturing entity may adhere RFID tags to components as they enter the production facility. These components are then inserted into the production flow, forming sub-assemblies in combination with other components, and finally resulting in a finished product. The use of RFID tags allows the personnel within the manufacturing entity to track the movement of the specific component throughout the manufacturing process. It also allows the entity to be able to identify the specific components that comprise any particular assembly or finished product. [0003] In addition, the use of RFID tags has also ...

AI Technical Summary

Benefits of technology

[0009] The use of this device is beneficial to many applications. For example, a newly developed integrity test is based on the concept of adding a tracer gas to a carrier. Detection of this tracer gas gives higher sensitivity than a standard diffusion test. The ability to detect this gas and transmit the results outside the filter housing would be greatly beneficial. In another application, the ability to monitor the protein concentration within the filter housing enables the operating conditions to be adjusted so as to maintain the protein concentration at the membrane surface for more reliable and reproducible performance.

Problems solved by technology

Despite the improvements that have occurred through the use of RFID tags, there are additional areas that have not been satisfactorily addressed.
