Abstract: In accordance with presently disclosed embodiments, systems and methods for efficiently handling dry additives to be mixed with bulk material in a blender are provided. The systems may include a support structure used to direct bulk material from one or more portable containers on the support structure to a first outlet location, and a combined metering/transferring system for directing dry additives from another portable container to a second outlet location. Specifically, the metering/transferring system may output a metered flow of dry additives to the blender mixer to be combined with bulk material that is released from the portable containers. The metering/transferring system may utilize a gravity feed outlet coupled to a metered screw or other conveying device to move the dry additive from the portable container to the second outlet location.

Abstract: The invention provides new systems/methods for providing oxygen to chronically ill patients, such as COPD patients, through a more efficient portable oxygen concentrator (“POC”) that at least sometimes delivers an enriched airflow having a significantly lower overall oxygen concentration than that administered by typical POCs. In aspects, the methods/systems of the present invention are configured to automatically switch from pulse delivery to continuous delivery, from continuous delivery to pulse delivery, or any combination thereof, at least once per day, when certain conditions occur. Methods/system can comprise the ability to switch between mode(s) comprising delivery of a moderately enriched oxygen airflow (MEOA) and mode(s) comprising delivery of intensively enriched oxygen airflow, highly enriched oxygen airflow, or both, and back again, based on one or more parameters.

Abstract: A load sense pump can be used as a backup for a pressure-compensated pump in a wellbore operation. A pumping system can include a first pump, a second pump, a check valve, and a directional control valve. The first pump, which can be a load sense pump, can be used to provide pressure to a first hydraulic load. The second pump, which can be a pressure-compensated pump, can be used to provide pressure to a second hydraulic load. The directional control valve can be controllable to cause the first pump to change operation to provide pressure to the first hydraulic load and through the check valve to the second hydraulic load.

Abstract: The disclosure provides a transportable system. The transportable system comprises a power distribution system comprising a first power distribution unit. The transportable system further comprises a first power module. The first power module is configured to provide energy in the form of rotational motion to the power distribution system, wherein the first power distribution unit comprises one or more power converters and an input connection, wherein the first power distribution unit is coupled to the first power module, wherein the rotational energy from the first power module is transferred to the one or more power converters via the input connection.

Abstract: The disclosure relates to a thermosiphon system operable to consistently maintain the permafrost and active frost layer in a frozen condition to adequately support buildings and other structures. During cooler seasons, the thermosiphon system uses a passive refrigeration cycle to efficiently maintain the frozen layers using the cold air. When the air temperature rises during the warmer months, the system transitions into an active refrigeration mode that uses a refrigeration system to minimize thawing or degradation of the permafrost and active frost layers.

Abstract: A pliable sheet is manufactured for use with smokable substances. The pliable sheet is completely sourced from female plants of the Cannabis genus. Source species include Cannabis sativa, Cannabis indica, or a blend thereof. A manufacture process entails processing and refining harvested plant material before it can be formed into the pliable sheet. After formation the pliable sheet is dried before it is ready for use. Flavoring and aromatic elements can be incorporated into the pliable sheet to enhance a smoking experience. Adhesives may also be integrated to facilitate rolling of the pliable sheet about smokable matter. Ideally, the adhesives are sticky oil extracts produced from plants of the Cannabis genus. The pliable sheet can be manufactured in a variety of thicknesses and sizes.

Abstract: Disclosed herein is a data encryption technique that pertains to a data stream that divides into data samples. Each sample is truncated by a predetermined number of bits to make room in the data stream for an encryption data packet. The truncation reduces the resolution of the data in exchange for security features. The encryption data packet includes a counter to prevent replay attacks and an HMAC to verify contents and synchronize the frames of the data stream. The data is encrypted and transmitted to a receiver where the data is played.
