Title: The Innovations of Charles H. Logan

Introduction

Charles H. Logan is a notable inventor based in Woodinville, WA (US). He has made significant contributions to the field of technology, particularly in the areas of mass spectrometry and respiratory detection. With a total of 3 patents to his name, Logan's work has had a meaningful impact on various applications in science and medicine.

Latest Patents

One of Logan's latest patents is the RF mass spectrometer. This innovative device includes an ion source for ionizing a sample substance, which provides an ion current of predetermined beam width and energy. The mass filter consists of a series of drift tubes, each increasing in length and separated by gaps that also increase in length. The ion current is supplied to the mass filter along with an alternating current electrical signal, allowing particles of a predetermined mass to receive a maximum energy increase while traversing the mass filter. A detector creates an energy barrier that only allows particles receiving the maximum energy increase to completely traverse it, enabling the detection of particles with a specific mass contained in the sample substance.

Another significant patent is the apparatus and method for inspiration detection. This invention provides a means for detecting patient inspiration by establishing a baseline level for the patient's respiration signal and a trigger level representative of inspiration. When the respiration signal crosses the trigger level, inspiration trigger signals are generated. The apparatus is designed to automatically detect shifts in the baseline level and re-establish the trigger level for the shifted waveform. This capability is crucial for accommodating both adult and neonate patients, making it a versatile tool in medical settings.
