Title: Prediction of rapid symptomatic blood pressure decrease
Inventor: SOERNMO LEIF
IPC: A61B5/021
Filed: 2007-06-04
Abstract: The invention relates to prediction of a rapid symptomatic drop in a subject's blood pressure, e.g. during a medical treatment or when operating an aircraft. To this aim, a pulse shape parameter (Pps) with respect to a peripheral body part (105) of the subject (P) is registered by means of a pulse oximetry instrument (110) adapted to detect light response variations in blood vessels. An initial pulse magnitude measure is calculated based on a pulse shape parameter (Pps) received at a first instance. During a measurement period subsequent to the first instance, a respective pulse magnitude measure is calculated based on each of a number of received pulse shape parameters (Pps). It is further investigated, for each pulse magnitude measure in the measurement period, whether or not the measure fulfils a decision criterion relative to the initial pulse magnitude measure. An alarm triggering signal (.alpha.) is generated if the decision criterion is found to be fulfilled.

Title: In-situ regeneration of a catalyst masked by calcium sulfate
Inventor: VECCI STANLEY J
IPC: B01D53/96
Filed: 2009-03-24
Abstract: An in-situ method for regenerating a deactivated catalyst removes a calcium sulfate layer masking active catalyst sites. A reducing agent converts the calcium sulfate to calcium oxide, which is then removed, by reintrainment into the flue gas steam using soot blowers or sonic horns. The method is particularly useful for regenerating selective catalytic reduction (SCR) catalysts used to remove nitrogen oxides from flue gas produced by combustion of coal from the Powder River Basin. The method can be practiced using existing SCR system hardware, and without removing the SCR system from service.

Title: Loudness controller with remote and local control
Inventor: CAROLL TIM J
IPC: H03G3/00
Filed: 2007-09-28
Abstract: A system and method associated with a recipient's audio equipment for maintaining desired loudness of a received audio signal is disclosed. The system includes a receiver device for receiving a broadcasted input signal and for transforming the input signal into a transport stream. The input signal and said transport stream have a non-processed audio signal component which contains its original dynamic range. A loudness controller is incorporated in the system so that it for receives the non-processed audio signal component of said transport stream and performs a process of dynamic range control on the non-processed audio signal component. A data signal containing settings for configuring the loudness controller is used for selectively controlling the operations of the loudness controller. The data signal allows external audio metadata to be accepted and used for control of the loudness controller. Alternatively, the loudness controller accepts external user input by the recipient to modify or tailor this consumer-side loudness controller to the taste or needs of the recipient. The loudness controller may also be bypassed to allow the original audio to pass un-modified.
