Title: Apparatus and method for enhancing productivity of natural gas wells
Inventor: WILDE GLENN
IPC: E21B43/12
Filed: 2003-04-09
Abstract: A natural gas production system prevents liquid accumulation in the wellbore and minimizes friction loading in the wellbore by maintaining production gas velocity above a critical minimum velocity. A pressurized gas is injected into the well to supplement the flow of production gas such that the velocity of the total gas flow up the well exceeds the critical velocity. A choke is fitted to the gas injection line, and total gas flows are measured by a flow meter. A flow controller compares the measured total gas flow rate against the critical flow rate, and determines a minimum gas injection rate required to maintain the total gas flow rate at or above the critical flow rate. The flow controller then adjusts the choke to achieve the desired gas injection rate. The injection gas may be recirculated production gas from the well, or a gas from a separate source.

Abstract: The effects of bad frames received over a communications channel by a speech decoder are concealed by replacing the values of the spectral parameters of the bad frames (a bad frame being either a corrupted frame or a lost frame) with values based on an at least partly adaptive mean of recently received good frames, but in case of a corrupted frame (as opposed to a lost frame), using the bad frame itself if the bad frame meets a predetermined criterion.  The aim of concealment is to find the most suitable parameters for the bad frame so that subjective quality of the synthesized speech is as high as possible.

Title: System and method for monitoring, managing and valuing credit accounts
Inventor: SULKOWSKI NIKOLAS
IPC: G06Q40/00
Filed: 2001-10-05
Abstract: The present invention relates to a system and method for estimating the futu re and present value of credit accounts (figure 1). A plurality of profit drive r segments (105) are established. A degree of belonging of the credit account to each of the plurality of profit driver segments (105) is determine by characterizing the credit account based upon it historical behavior (110). T he probability of migration of the credit account from at least one profit driv er segment (105) to at least one profit driver segment based upon historical behavior data is determined. The credit account can then be valued based upo n the characterization of the credit account and the determined probability of  migration. By examinating how accounts migrate between behavior segments ove r multiple periods, and analyzing the discounted cash flows associated with these migration patterns, a net present value may be calculated for each account.

Abstract: A helm apparatus for a marine craft or other vehicle having a steered member such as a rudder includes a mechanically rotatable steering device and a sensor which senses angular movement of the steering device when the craft is steered. A communication link to the rudder enables the helm to monitor the rudder position. A bi-directional stop mechanism is actuated when the helm determines that the rudder position is beyond starboard or port hard-over thresholds, indicating that the rudder has reached a limit of travel. The helm can cause the stop mechanism to fully engage the steering device to stop further rotation of the steering device in a first rotational direction, corresponding to rotational movement towards said limit of travel. Rotational play is provided between the sensor and the stop mechanism, whereby the steering device can be rotated a limited amount, relative to the sensor, when the stop mechanism is fully engaged. The stop mechanism is released from engagement with the steering device when the sensor senses that the steering device is rotated, as permitted by said play, in a second rotational direction which is opposite the first rotational direction. Additionally, the same stop mechanism, or an optional steering effort mechanism, can be used to provide a dynamic steering effort, whereby the torque required to rotate the steering shaft is varied based on system inputs and configurations. The required torque is changed by fluctuations of the amount of friction between the steering effort mechanism and steering shaft, based on system inputs and configurations.
