  • Multibeam, digitally modulated, time division, switched satellite communications system
    Patent number: 4105973
    Abstract: The present invention relates to a multibeam, digitally modulated, time division switched communication system especially for use with a satellite repeater wherein separate up-link and down-link signals are transmitted between each of a plurality of ground station areas and the repeater using space diversity techniques. The frequency band of each up-link signal is split to include at least two frequency multiplexed channels, each channel being separated at the repeater and independently switched at baseband frequencies through a repeater switching network comprising at least two matrix switches for retransmission on the appropriate down-link signal.

  • AUTOSAMPLER
    Publication number: 20210270783
    Abstract: Embodiments of the disclosure relate to chemical analysis systems, including autosampler systems. In some embodiments, an autosampler system can analyze gas phase samples using a single inlet for better consistency. The autosampler system can move the sample container closer to the sample introduction/preconcentration system prior to accessing the contents of the container to reduce exposure of the sample to reactive surfaces. The autosampler system is able to couple the sample containers to a sampling wand automatically, thereby eliminating the need to pre-attach each container using a gas transfer line. The autosampler system can be disposed on top of a chemical analysis system (e.g., a GC or GCMS), thereby conserving laboratory bench space. In some embodiments, the modules (e.g., sample trays, thermal conditioning systems, support legs) of the autosampler system can be coupled to the autosampler system using clamps that include magnetic codes associated with autocalibration information.

  • Integrated system for gathering, processing, and reporting data relating to site contamination
    Patent number: 5687093
    Abstract: An integrated screening system comprises an intrusive sampling subsystem, a field mobile laboratory subsystem, a computer assisted design/geographical information subsystem, and a telecommunication linkup subsystem, all integrated to provide synergistically improved data relating to the extent of site soil/groundwater contamination. According to the present invention, data samples related to the soil, groundwater or other contamination of the subsurface material are gathered and analyzed to measure contaminants. Based on the location of origin of the samples in three-dimensional space, the analyzed data are transmitted to a location display. The data from analyzing samples and the data from the locating the origin are managed to project the next probable sample location. The next probable sample location is then forwarded for use as a guide in the placement of ensuing sample location, whereby the number of samples needed to accurately characterize the site is minimized.

  • Methodology for three-dimensional morphological and quantitative determination of micro and nanocavities produced by chemical and microbiological corrosion in metallic materials
    Publication number: 20160245738
    Abstract: The present invention refers to a procedure which includes the following objectives: a) To determine the morphology of the micro and nanocavities produced by chemical and/or microbiological corrosion in metallic materials, in the space of three dimensions as well as the effective advance of corrosion, the true length of corrosion cavities and their associated parameters: corrosion vectors, corrosion intensity and determination of the cavities diameter/true length of corrosion ratio, applying scanning electron microscopy (MEB) techniques, and analytic, gravimetric and volumetric formulations; b) To quantitatively determine the rate of chemical and/or microbiological corrosion in metallic materials, through their volumetric and gravimetric properties; and c) To obtain a graphic interface to access the numeric information and the micrographs in a simple and friendly manner.

  • Systems and methods for preparing dental restorations
    Publication number: 20120110851
    Abstract: Improved systems and methods for producing dental restorations and ceramic materials for such restorations are disclosed. Optical properties, preferably including color and translucence characteristics, of a tooth or teeth of a patient are measured with a shade measuring instrument. The tooth to be restored is prepared, and a physical or virtual dental impression is created. A prescription for the restoration, which typically includes color, translucence and thickness information, is sent to the restoration fabrication facility either electronically or physically. A recipe and/or a mixture of ceramics are generated for the restoration, with multiple layers being specified, based on the measured optical properties. The recipe algorithm may adapt, or process checks may be performed, based on measurements of fabricated layers. Preferably, dental ceramics are specified to bracket the region of color space relevant to human teeth, and a reduced set of ceramic materials are manufactured and distributed.

  • Convertible folding box
    Patent number: 5934549
    Abstract: A new type of folding box is disclosed, which is designed for redispatching to a second location, after it has been received at a first location. This box, which can be made from a single flat pre-cut blank, of cardboard or other suitable material, has two lids: an inner lid, and an outer lid. The outer lid is printed, stamped, or affixed with advertising information, a first mailing address, or other useful lettering, to facilitate a first delivery or sale. The inner lid, which is initially covered and preferably hidden by the outer lid, is printed or stamped with a second lettering, such as a second mailing or delivery address. The user purchases or otherwise receives the complete box, including the outer lid, and carries out any desired function with the contents of that box. For example, if the box contains collection jars, for holding blood, hair, water, or soil samples, the user would fill the jars with such samples or specimens.
