Patent number: 7960176Abstract: A method and device for determining whether a product is in condition to be used or consumed, this product being intended to be preserved under temperature conditions and for a period of time which limit its degradation includes an indicator combined with the product, to provide a signal indicating that the product can be used or consumed, and then, after the expiration of a preservation period of time, a signal indicating a change in the condition of possible use or consumption of the product. The period of time depends on the preservation conditions of the product. The indicator provides information enabling the product to be used or consumed for a longer period of time if the product has been preserved under conditions better than recommended conditions or for a shorter period of time if the product has been preserved under conditions worse than recommended conditions.Type: GrantFiled: September 17, 2004Date of Patent: June 14, 2011Assignee: Cryolog SAInventors: Olivier Louvet, Dominique Thuault, Renaud Vaillant

Patent number: 7919324Abstract: A liquid testing device for determining the value of at least one property of a liquid. The liquid testing device includes a planar base and at least one test section, located on the planar base, with a reference color section located adjacent to the test section, which exhibits a color according to the value, as a result of reaction of a reagent with the liquid. The reference color section includes a plurality of different reference colors arranged for easy visual color comparison with the test result. The reference color section is placed adjacent to and in contact with the test section, with the test section having sufficient length so that it substantially encompasses the entire reference color section with its plurality of different reference colors. Thus, when the test section exhibits a reaction color, the visual comparison is simplified since the reference color which matches the reaction color becomes substantially visually merged and self-aligned therewith.Type: GrantFiled: December 12, 2007Date of Patent: April 5, 2011Assignee: Orit Marom-AlbeckInventor: Orit Albeck-Marom

Patent number: 7901627Abstract: 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.Type: GrantFiled: May 27, 2009Date of Patent: March 8, 2011Assignee: Millipore CorporationInventor: Anthony DiLeo
