Patent number: 8084259Abstract: The present invention describes a system for accurately measuring the concentration of a substance within a filter housing. A concentration sensor and a communications device are coupled so as to measure and transmit the concentration of a particular substance within the filter housing while in use. This system allows the operator to certify the integrity of the filters within the filter housing at the customer site without additional equipment. In one embodiment, a tracer gas, such as helium or hydrogen, is added to a carrier and injected into the system. The concentration of tracer gas at a specific operating transmembrane pressure is indicative of bubble pointing specific pores in the filter. This test will give a more sensitive indication of the bubble point and the presence of defects than a standard diffusion test. In a second embodiment, two gasses, in a known ratio, are introduced into the filter housing.Type: GrantFiled: December 5, 2008Date of Patent: December 27, 2011Assignee: Millipore CorporationInventor: Anthony DiLeo

Patent number: 8082103Abstract: Hourly CO2 concentration, amount of solar radiation, and plant distribution information are calculated through observation from predetermined satellites. A concentration of CO2 absorbed by plant-chlorophyll per each time unit is calculated. By adding up the CO2 concentration on the earth and the concentration of CO2 absorbed by the plant-chlorophyll, a CO2 concentration obtained provided that no plant-chlorophyll exist is calculated for a certain period. Thereafter, a mean concentration of CO2 that is absorbed according to changes in the distribution of plant-chlorophyll is calculated on the basis of a monthly mean solar radiation amount and plant-chlorophyll distribution information. By subtracting the CO2 concentration, which is a mean, from the total CO2 concentration, a CO2 concentration, which is a normal, is calculated.Type: GrantFiled: July 15, 2010Date of Patent: December 20, 2011Assignee: Fujitsu LimitedInventor: Shuichi Tanahashi

Publication number: 20100258718Abstract: The present invention relates to identification tagging, and is specifically directed to identification tagging of ammunition. An isotopic taggant is deposited in a layer at the interface between the primer and the propellant so that, as the ammunition is fired, the taggant is dispersed throughout the propellant. The taggant is thus contained in the gunshot residue formed during the firing, and can be read by analysis of residue particles. Alternatively, the taggant may be deposited in a layer under the primer reactants, or in pellets which are easily destroyed by the chemical reactions involved in firing the ammunition, again dispersing the taggant throughout the propellant and the gunshot residue. Non-isotopic chemical taggants may also be employed if they are encoded so as to minimize the possibility of the information being destroyed or improperly read after the taggants are exposed to the chemical reactions in firing the ammunition.Type: ApplicationFiled: September 18, 2006Publication date: October 14, 2010Inventor: Richard P.

Patent number: 6804549Abstract: A method and system by which the sentinel lymph node, which is the first lymph node to which cancer is transferred when cancer is transferred to lymph nodes, is detected easily and with a high degree of accuracy. A fluorescent colorant is injected near a tumor, and after a predetermined period of time an abdominal operation is performed and stimulating light is projected onto the area being examined. Because the fluorescent colorant has been accumulated on the sentinel lymph node, it emits fluorescent light, which is then magnified and converted to a visual image. The examiner can view the normal image and the visible image at the same time. Because the stimulating light is in the near-infrared wavelength band, which is difficult for the fatty and other tissue that cover the sentinel lymph node to absorb, the sentinel lymph node is detected from the surface of the tissue.Type: GrantFiled: April 25, 2001Date of Patent: October 12, 2004Assignee: Fuji Photo Film Co., Ltd.Inventor: Katsumi Hayashi

Pattern method and system for detecting foreign object debris using a fluorescent drilling lubricant
Publication number: 20040113071Abstract: A method of detecting a non-fixed object created during hole drilling operations on a system (12) includes applying a light emitting lubricant (25) to a drill bit (37) of a hole-drilling device (31). The light emitting lubricant adheres to foreign object debris 10 that is created during the hole drilling operations. The foreign object debris 10 can include shavings (29), portions of the drill bit (37), or the entire drill bit (37). The objects are illuminated with an object illuminator (16). At least one of the objects (10) is determined to be a nonmember within a known pattern of objects and is identified to be a non-fixed object in response to illumination of the objects.Type: ApplicationFiled: November 24, 2003Publication date: June 17, 2004Inventors: Greg L. Benfer, Daniel E. Wagoner, Michael L. Taylor, John D. Fitts, John C. Clayton, Lynn E. Johnson -
Publication number: 20040113070Abstract: A fluorescent trace material is provided within at least a portion of an electrical contact or interrupter assembly component, or a cavity defined therein. At least a portion of the fluorescent trace material is exposed or released from the electrical contact or interrupter assembly component, indicating a degree of component wear.Type: ApplicationFiled: December 13, 2002Publication date: June 17, 2004Inventor: Bruce Nichols

Patent number: 6740875Abstract: A covert, gamma-ray “signature” is used as a “watermark” for property identification. This new watermarking technology is based on a unique steganographic or “hidden writing” digital signature, implemented in tiny quantities of gamma-ray-emitting radioisotopic material combinations, generally covertly emplaced on or within an object. This digital signature may be readily recovered at distant future times, by placing a sensitive, high energy-resolution gamma-ray detecting instrument reasonably precisely over the location of the watermark, which location may be known only to the object's owner; however, the signature is concealed from all ordinary detection means because its exceedingly low level of activity is obscured by the natural radiation background (including the gamma radiation naturally emanating from the object itself, from cosmic radiation and material surroundings, from human bodies, etc.).Type: GrantFiled: February 11, 2000Date of Patent: May 25, 2004Assignee: The Regents of the University of CaliforniaInventors: Muriel Y. Ishikawa, Lowell L. Wood, Ronald W. Lougheed, Kenton J. Moody, Tzu-Fang Wang

Patent number: 6737645Abstract: A method for determining whether effective coverage of the interior of a bottle with a sprayed sanitizer in a bottle fill-and-cap operation is attained by using a fluorescing solution, preferably comprising riboflavin and sucrose dissolved in water, that is sprayed on the interior of the bottle by the same spray system by which the sanitizer is sprayed. After application of the fluorescing solution, UV light is applied to the bottle interior to activate the fluorescing solution and thus make evident the spray pattern. Spray pattern adjustments can be made as needed, in order to be certain that the entirety of the inside surface of the bottle is coated. Once the spray pattern is thus set, the equipment is qualified to be used for production, with the sanitizer being sprayed according to the same spray pattern.Type: GrantFiled: August 30, 2002Date of Patent: May 18, 2004Assignee: Tropicana Products, Inc.Inventors: Tammy Foster, Christine Jansen, James D.

Publication number: 20040079903Abstract: The present invention provides a device that uses an ultraviolet LED to locate fluorescent materials. In particular, the present invention is directed to a device that is used to detect leaks, cracks or fissures in a contained system, such as, for example, an air conditioning system for a vehicle. The device has a main body, an ultraviolet LED mounted to the main body so that ultraviolet light from the LED is directed away from the device, and a power source linked to the ultraviolet LED to provide power to the LED. The ultraviolet LED can be an UVA LED. Moreover, the wavelength of the ultraviolet light produced by the LED is about 315 nm to about 400 nm. The method of the invention for locating fluid leaks can comprise, for example, introducing an ultraviolet dye into a fluid in a contained system, such as, for example, an air conditioning system of a vehicle, and illuminating an area of the system to be checked for fluid leaks with an ultraviolet LED light source.Type: ApplicationFiled: October 23, 2003Publication date: April 29, 2004Applicant: J.L.
