Abstract: An arrangement for producing a fibrous mat from a heated die source wherein the produced mat includes a first layered, preselected fiber portion of substantially straight fibers produced by directing such fibers directly to a collector source and a second layered preselected fiber portion of substantially curled fibers produced by diverting and exerting an external vortically creative curling force thereon before reaching the collector source.

Abstract: A filter medium and frame therefore wherein the filter medium is treated by a novel adhesive comprised of a major portion by weight of an oil group consisting of vegetable and animal oils and a minor portion of a preselected thickening material with the rigidity of the filter medium being obtained by sandwiching the filter medium between joined mating upstream and downstream frame members.

Abstract: A low-error fixed-width multiplier receives a W-bit input and produces a W-bit product. In an embodiment, a multiplier (Y) is encoded using modified Booth coding. The encoded multiplier (Y) and a multiplicand (X) are processed together to generate partial products. The partial products are accumulated to generate a product (P). To compensate for the quantization error, Booth encoder outputs are used for the generation of error compensation bias. The truncated bits are divided into two groups, a major least significant bit group and a minor least significant bit group, depending upon their effects on the quantization error. Different error compensation methods are applied to each group.

Abstract: There are provided thermotropic liquid crystal polymer microcapsules which can show behavior of liquid crystal as it is within polymer phase due to phase separation between liquid crystal and polymer, so to be incorporated into cosmetic composition as an additive for visual effect, and in loading active ingredients within liquid crystal, can improve the stability of the active ingredients in cosmetic base; and a method for preparing the same; and cosmetic compositions containing the same.

Abstract: An arrangement for forming a web of fibrous media wherein at least one formed layered portion is attenuated from a first die source selectively unto a first collector and successively combining such portion with at least another formed layered portion which is attenuated from a second die source selectively unto a second collector, at least one of the outer surfaces of the web of fibrous media being of comparatively smooth skin-like nature to minimize projecting fiber ends.

Abstract: A methodology to automatically measure network parameters relating to wireless network environments is disclosed. First, if a server's telephone number is detected from power-on registration data stored in a storage device, then a connection with the server is attempted through a mobile station with a data service function using the server's telephone number. Thereafter, if there is test plan from the server after the connection is made, the network parameters is measured using another mobile station with a diagnostic monitor function based on the test plan data. The measured network parameters is then collected and parsed to obtain sets of measured network parameters, each set having a different kind of measured data; and the sets of measured network parameters are transmitted to the server using the mobile station with the data service function when there is a data transmission request from the server or it is time for data transmission.

Abstract: A unified arrangement for providing a unique nanofibrous porous media formed as a chemical compound from a water-soluble polymer combined with a cross-linking agent with a balance of water, which chemical compound prevents the polymer from dissolving in water, including a humid environment.

Abstract: A filter media product and method of making the same wherein at least two independent filter media thicknesses of differing coarse and fine pore sizes are held in face-to-face relationship with the pore sizes being so calculated that the overall average pore size of successive thicknesses is smaller than the pore size of the finest fiber thickness.
