摘要： The method and device of the present invention reduces the pulsation of fluid from a pump. The damping device and method works on either the positive pressure or negative pressure side of the pump. Under positive pressure the device is attached downstream from the outlet port of a pump, the device having an input port in fluidic communication with the outlet port of the pump, an outlet port, an outer wall with an opening, and a membrane covering the opening, the outer wall of the device and the membrane forming a contained volume. As fluid from the outlet port of the pump passes into the device, it enters the contained volume which expands and contracts, thereby vitiating the pulsations in the fluid flow downstream of the device. Alternatively, under negative pressure the device is attached upstream from the inlet port of a pump.

摘要： A method is provided for modifying a wavelength of electromagnetic radiation that propagates through a medium. The method includes providing a medium that exhibits a change in refractive index in response to a change in electric field; impinging electromagnetic radiation from a electromagnetic radiation source onto the medium such that the electromagnetic radiation propagates through the medium; and modifying at least one wavelength of the electromagnetic radiation propagating through the medium by externally inducing a temporal change in the refractive index of the medium.

摘要： A sampling system is disclosed which comprises a collection chamber equipped with an inlet and first and second outlets; a pump which creates a flow of fluid into said inlet from the ambient environment, wherein said collection chamber divides the flow of fluid into a first major flow of fluid along which flows along a first flow path between said inlet and said first outlet, and a second minor flow of fluid which flows along a second flow path between said inlet and said second outlet; a collection surface disposed within said collection chamber and within the second flow path such that particles in the flow of fluid into said inlet impinge on said collection surface; a heater which vaporizes particles that collect on said collection surface; and an analyzer which analyzes the composition of the fluidic flow through said second outlet.

摘要： In accordance with one embodiment of the present invention, a data acquisition and control system includes a sample manifold for collecting air samples. The manifold may include twenty-eight discrete sorbent tubes. Each sorbent tube may be sealed within the manifold and the manifold may be removed from the system for sorbent tube analysis. A second manifold may be connected to the system for continued air sampling collection. The system may autonomously collect multiple samples at scheduled or triggered events. The system may also communicate with other systems to form a multi-system monitoring network. The system may also interface and operate with a multitude of sensors and monitors of different types.

摘要： Technologies are provided for assessment of exposure to airborne aerosol pathogens (e.g., SARS-CoV-2). Exposure can be assessed using a model that yields a score quantifying comparative dose which can be classified into an exposure risk category in a particular scenario relative to a high-risk scenario. The model incorporates mechanistic, stochastic, and epidemiological factors that define the particular scenario within an activity region. The model can determine an average concentration of pathogen within the activity region, for a particular exposure duration, using an approach that includes near-field and far-field contributions. In some embodiments, an apparatus can access data from various devices. The data defines at least some of the factors the define the particular scenario. The apparatus can determine an average concentration within the activity region, and can cause a display device to present indicia indicative of the exposure risk.
