Abstract: A device collects material from air. The device swirls air within a fluid housing so as to deposit the material, such as viruses, bacteria, fungi and other particles, from the air in a way that the material can later be analyzed. The device can be used to provide for detection of airborne organisms or properties of material in the air.

Abstract: Systems and methods for predictive management of plants. Agricultural (and natural resource) managers may have a multitude of data sets and data sources available, but often lack a meaningful or proven way to assimilate all available data and then conclusively select actions. For example, a vineyard manager may be able to collect data about local and regional weather, precipitation, disease prevalence, insect prevalence, pesticide use, crop varietal, cover crop selection and many other inputs to a predictive machine-learning vineyard management engine. As all this data is collected through local devices and third-party services, a prediction model may be used to determine specific outcomes or recommended actions based on the trained predictive model. For example, the model may be used to predict optimal harvest date, disease spread and vector spread, pest spread and impact, best pesticide use, irrigation plans, fruit quality, and the like.

Abstract: Apparatuses and methods of using them to collect blood, are provided, by first ensuring that the patient's skin is properly cleaned, to prevent contamination of the collected blood. One feature is a blood collection device configured to collect blood from a patient. Another feature is a scrub timer integrated into the device and configured to indicate to a user a scrub time period prior to beginning a blood draw process. The scrub timer can be configured to audibly and/or visually indicate to a user the start and stop times of a scrub cleaning process. In one embodiment, the scrub timer can be restarted, either manually or automatically, if the scrub cleaning process is not followed properly.

Abstract: The present disclosure relates to deployable structures and methods of use thereof. In particular, deployable structures with non-cylindrical or irregular shapes and methods of use thereof are disclosed. Non-cylindrical combustion elements can be used to rigidize such non-cylindrical or irregular shapes. The use of gaseous oxidizers along with deployable structures is also disclosed.

Abstract: Systems and method for analysing contaminants of a gas sample of natural gas are provided. An interrogation light beam propagates into a chamber of a multipass gas cell receiving the gas sample. The interrogation light beam has a wavelength controlled to alternately correspond to an absorption wavelength of H2S and an absorption wavelength of an additional gas contaminant. The additional gas contaminant may for example be CO2 or H2O. In some implementation, a single laser emitter may be used to generate the interrogation light beam at the H2S and CO2 wavelengths. In some implementations, two different laser emitters may be used to generate the interrogation light beam at the H2S and H2O wavelengths. A WMS detection scheme may be used.

Abstract: A method for liquefaction of coal or other solid carbonaceous material includes passing the material through a reformer having a temperature gradient therein, the temperature gradient generally increasing as the material flows down through the reformer. The more valuable volatile components of the material exit the material at their respective vaporization temperatures, and pass out of the reformer for processing in condensers. Some of each fraction of the volatile material flow is re-heated and recycled through the reformer to supply heat to maintain the temperature gradient, the recycling injection occurring at a level below that where the fraction exited the reformer so that the recycled fraction will again pass out of the reformer to be condensed. At the bottom of the reformer, the non-volatile portion of the carbonaceous material is removed from the reformer for further processing or sale.

Abstract: Methods and apparatus collecting blood from patients and managing blood donations are provided, which may include any number of features. One feature is a blood collection device configured to collect blood from a patient and periodically transmit blood collection data from the device to a control system. Another feature is a system and method for updating firmware on a plurality of blood collection devices. In one embodiment, a software interface with a blood collection control can be used to specify a blood collection protocol, and the blood collection protocol can be then transmitted to one or more blood collection devices.

Abstract: A method for determining attenuation of electromagnetic waves impacting an electromagnetic shield. A reference amplitude is provided. A signal exhibiting a first frequency is converted to a converted signal exhibiting a second frequency higher than the first frequency. Electromagnetic waves corresponding to the converted signal are transmitted from a first antenna toward a second antenna with the electromagnetic shield positioned between them. Attenuated remnants of the electromagnetic waves received by the second antenna are converted to a corresponding signal exhibiting a third frequency that is lower than the second frequency. The amplitude of the corresponding signal is compared to the reference amplitude.
