Abstract: When Severe Acute Respiratory Syndrome (SARS) outbreak occurred in Toronto in 2003 a large number of hospitals throughout North America and Europe purchased and trained employees on using class N95 respirators in preparation of a potential outbreak in their area These respirators require fit testing to ensure that they are the proper size and have a "tight face to mask" seal.   Current quantitative fit testing for N95 respirators use a condensation particle counter (CPC), in combination with an additional instrument, that alters the size range of the ambient particles used for the fit test measurements. Therefore the only particles used are particles that can be trapped by class 95 filters This fit testing process slows the normal respirator fit test time when using the CPC  test instrument alone.   The objective of this invention is to provide a process that allows N95 respirators to be quantitatively fit tested without the use of an additional instrument that alters the size range of the ambient particles.   We are not aware of any other inventions that aim to reduce the fit testing time of quantitative fit testing N95 respirators using CPC technology.   This invention aims to quantitatively fit test N95 respirators as quickly as respirators.

Abstract: The invention relates to a method for controlling/regulating a physical quantity of a dynamic system with regard to a specified progression of set values. To this end, a pulse modulator is used that generates a series of discrete modulation signals that effect the control or regulation of the physical quantity. The following steps are repeatedly carried out: a) determining an exact value or an approximation for the difference between the instantaneous set value and the instantaneous actual value of the physical quantity; b) determining the respective change in the difference that would have resulted in the maintaining of the instantaneous modulation signal or the moving to the other modulation signals, and; c) generating the modulation signal that leads to the best approximation of the instantaneous set value.

Title: Floating dc-offset circuit for phase detector
Inventor: EVSTRATOV LEONID V
IPC: H03L7/08
Filed: 2007-12-04
Abstract: A floating DC-offset circuit for a phase detector. The circuit may provide a floating DC-offset to the phase detector, or to the voltage-controlled oscillator of the phase-locked loop. The circuit includes a voltage comparator, a clock, a digital resistor, and an offset line to a DC-offset branch of the phase detector.  The voltage comparator detects when the voltage at the output of the loop filter of the phase-locked loop has gone outside of a designated range, and activates the clock when the voltage is outside the designated range. The clock emits impulses that are counted by the digital resistor. The digital resistor shifts DC-offset at the DC-offset branch of the phase detector. The new UC-offset level is maintained once the voltage at the output of the loop filter has returned to within the designated range. In an alternate embodiment, the DC-offset branch is connected to rough-tuning input of a wide-tuned voltage-controlled oscillator.
