Filed: 2000-05-09
Abstract: A drip chamber for an intravenous fluid delivery system includes a housing having an inlet port and an outlet port, the inlet and outlet ports each having an inner diameter, and the housing defining a chamber between the inlet and outlet ports. The housing configured to channel intravenous fluid in a flow path from the inlet port through the chamber and to the outlet port. A member supported in the chamber between the inlet and outlet ports is positioned so that the intravenous fluid flowing through the chamber impinges against the member to reduce the velocity of the intravenous fluid and minimize formation of air bubbles in the intravenous fluid. The inner diameter of the inlet port being substantially equal to or greater than the inner diameter of the outlet port, such that a flow rate of the intravenous fluid exiting the outlet port is substantially equal to or less than a flow rate of the intravenous fluid entering the inlet port.

Title: Device and method for transmitting subframe in mobile communication system
Inventor: PARK CHANG-SOO
IPC: H04B1/707
Filed: 1999-09-01
Abstract: A subframe data transmission device for a mobile communication system. A bit generator generates specific bits having a predetermined value. A bit inserter segments a received data bit stream into at least two subframes, and inserts the generated specific bits at locations where an error probability is higher in the respective subframes. A turbo coder codes the subframe data comprised of the data bit stream and the specific bits.      The subframe is equal in size to an ARQ (Automatic Repeat Request) block, and the specific bits are inserted at a rear portion of the subframe. The bit inserter includes a delay for delaying the received data bit stream by the number of the specific bits to be inserted; and a selector for connecting, upon completion of receiving data bits for the subframe, the received data bits to the delay and applying an output of the bit generator to the turbo coder; and applying, when the specific bits are inserted, an output of the delay to the turbo coder.

Title: Computer system and process for a credit-driven analysis of asset-backed securities
Inventor: ERVOLINI MICHAEL A
IPC: G06Q40/08
Filed: 1999-03-10
Abstract: A computer system or computer-implemented process that analyzes pools of loans by considering the combination of interest rates and credit quality which drive asset performance or by incorporating financial reporting. The analysis is called credit-driven because the level of prepayment simulated for each asset in the pool is modulated separately over a projection period based on the projected financial performance of the underlying collateral. Prepayments occur when prepayment is permitted and refinancing results in some specified level of net new proceeds. Similarly, this analysis modulates the level of default simulated for each asset in the pool separately over a projection period. Credit-driven defaults occur when the underlying collateral's net income is insufficient to cover debt service. Following a specified delay, the severity of loss may be computed to reflect the underlying collateral's performance and financeability. Similarly, this analysis modulates the amount of extension simulated for each asset in the pool separately over a projection period. Credit-driven extensions occor when the underlying collateral's income and value are insufficient to support financing of the asset's scheduled balloon payment. Following a specified delay, the balloon repayment is again simulated at which time the asset may experience a balloon shortfall. Such balloon shortfall or calculated severity of loss may be computed to reflect the underlying collateral's performance and financeability.

Title: Non-destructive analysis of a semiconductor using reflectance spectrometry
Inventor: CHERKASSKY ALEXANDER P
IPC: G01N21/35
Filed: 1999-04-20
Abstract: A method for the determination of parameters of interests of a semiconductor sample is provided. For example, the thickness of an epitaxial or implanted layer, the thickness of a transition layer, and the concentration of free carriers in a substrate layer may be determined without having to destroy the semiconductor sample in the process. In an embodiment, a method starts by measuring an experimental reflectance spectrum of the semiconductor (202). An analytical model of the semiconductor having a film layer, a transition layer and a substrate layer is then constructed (208). Next, optical constants n and k for the film layer, transition layer, and substrate layer are expressed as a function of doping level (210). A profile of the transition layer is determined (211), and if an abrupt profile exists, the transition layer is further modeled as having a plurality of sections, wherein each of the sections is assigned an s-polarization matrix and a p-polarization matrix. An overall modeled reflectance spectrum is then calculated (212) and the parameters therein are varied to achieve a best fit relationship with the experimental reflectance spectrum (214). Thus, the parameter of interest can be determined (216).

Abstract: A method for controlling a NOx removal system in which reductant supply is adjusted according to combustion level in a boiler (1) in which the combustion level is controlled in multiple stages. For a decrease of the combustion level, the reductant supply is kept lower than a level corresponding to a changeover-target combustion level for a period of a set time from the changeover of the combustion level. Thus, when the reductant supply is changed over in response to a changeover of combustion level, the reductant can be prevented from flowing outside as it is unreacted.

Abstract: A simulator having a computer-aided design (CAD) programs for verifying algorithms of a shift controller of an automatic transmission. The simulator includes a simulator main unit (a computer) which stores the programs and inputs the algorithm, and pseudo-signal generator which generates pseudo signals including operation signals for the hydraulic actuators. The programs includes first calculating means for calculating outputs of first to third models describing behavior of the engine, the transmission and the vehicle body at a first calculation cycle based on the algorithm and the pseudo signals. A second calculating means inputs the calculated outputs of the first and second models and calculates an output of a fourth model describing non-linear behavior in the second model at a second calculation cycle, shorter than the first calculation cycle, and verifies the algorithm based on the outputs of the first models. With this, it can simulate in real time the behaviors of the automatic vehicle transmission including the non-linear behavior of hydraulic actuators, thereby enabling verification or evaluation of the control algorithm in a real-world environment.
