摘要:
A miniature, low cost mass spectrometer capable of unit resolution over a mass range of 10 to 50 AMU. The mass spectrometer incorporates several features that enhance the performance of the design over comparable instruments. An efficient ion source enables relatively low power consumption without sacrificing measurement resolution. Variable geometry mechanical filters allow for variable resolution. An onboard ion pump removes the need for an external pumping source. A magnet and magnetic yoke produce magnetic field regions with different flux densities to run the ion pump and a magnetic sector mass analyzer. An onboard digital controller and power conversion circuit inside the vacuum chamber allows a large degree of flexibility over the operation of the mass spectrometer while eliminating the need for high-voltage electrical feedthroughs. The miniature mass spectrometer senses fractions of a percentage of inlet gas and returns mass spectra data to a computer.

An electric motor including: a first and second linear actuator, each linear actuator including a first and second coil respectively, a rotational shaft, a cam assembly mounted on the rotational shaft for translating linear movement of the two linear actuators to rotational movement of the rotational shaft, a controller programmed to generate during operation a first and second drive signal for first coil and second coil respectively, wherein the first drive signal causes the first linear actuator to generate a first torque on the rotational shaft that varies periodically over a complete rotation of the shaft and the second drive signal causes the second linear actuator to generate a second torque on the rotational shaft that varies periodically over a complete rotation of the shaft, and wherein the sum of the first and second torques produces a total torque that is substantially constant throughout the complete rotation of the shaft.
摘要:
Quantum simulation methods are used to encode the quantum response of a molecular system so as to improve the sensitivity for detection of a target material, while rejecting background. The perturbation and response information may be used to discover the system function of a quantum system, or more generally, of a complex system, such as a physiological system. The approach may be applied to medical non-invasive, real-time, continuous molecular detection and quantification techniques through coherent Raman spectroscopy to enable a significantly more attractive course of therapy than existing protocols.
摘要:
An acoustic system can track gas emissions by exploiting the nostril-accessible nasal pathways of an animal. Actuators and microphones used in the apparatus can be similar to those currently found in cell phones, which in turn make the acoustic apparatus small and rugged. The nostril geometry can be mapped using sound waves, similar to the mapping done by an acoustic rhinometer. Where acoustic rhinometers assume a constant speed of sound to measure changes in geometry, acoustic approaches as disclosed herein can assume constant geometry to measure changes in the speed of sound. Approaches disclosed here are particularly useful with any gas, such as (for example) methane, hydrogen, helium, etc. that has a speed of sound higher than other typical gaseous components of exhaled air, such as nitrogen, carbon-dioxide, oxygen, etc.
