Abstract: A re-usable, returnable, stackable, modular shipping base that incorporates replaceable components to make the base relatively quick and cost effective to repair. The shipping base is formed from a number of stamped or cut sheet materials (e.g., sheet metal) that are then folded and attached to one another using a tab system. When a component is damaged, the damaged component may be removed from the base and replaced with another mass produced, stamped sheet material component. Components are attached to one another via adhesive, rivets, stitch welding, spot welding, or any other applicable process.

Abstract: An online agricultural system manages and optimizes interactions of entities within the system to enable the execution of transaction and the transportation of crop products. The online agricultural system accesses historic and environmental data describing factors that may impact crop product transactions and/or transportation to determine market prices for crop products and crop product transportation. Responsive to receiving a request from an entity, the online agricultural system determines an optimal transaction for the entity, such as a price for selling a crop product, an available crop product for purchase, or a transportation opportunity to transport a crop product.

Abstract: A sorting system including a flow cell with a first inlet, a second inlet, and an outlet. The sorting system also includes a buffer supply in fluid communication with the first inlet, a sample source in fluid communication with the second inlet, a light source configured to generate a light beam that intersects the flow cell, and a sensor aligned with the light source and configured to detect a characteristic of the light beam. An air valve is configured to generate an airflow at the outlet of the flow cell, and control of the air valve is based on the characteristic of the light beam detected by the sensor.

Abstract: A system for tracking anesthetic agent in a vaporizer reservoir can include a mass flow sensor configured to measure a flow rate entering or exiting a vaporizer chamber, a gas pressure sensor configured to measure a pressure of a mixed gas provided from the vaporizer chamber, and a processor to calculate a remaining agent time based on at least the gas flow rate, the pressure of the mixed gas, and an anesthetic concentration in the mixed gas. The processor can also provide the remaining agent time for display to a clinician.

Abstract: A system for tracking anesthetic agent in a vaporizer reservoir includes a mass flow sensor configured to measure a flow rate entering or exiting a vaporizer chamber, a gas pressure sensor configured to measure a pressure of a mixed gas provided from the vaporizer chamber, a gas temperature sensor configured to measure a temperature of the mixed gas provided from the vaporizer chamber, and an agent time module executable on a processor. The agent time module is configured to calculate a remaining agent time based on at least the gas flow rate, the pressure of the mixed gas, the temperature of the mixed gas, and an anesthetic concentration in the mixed gas. The remaining agent time is then provided for display on a display device.

Abstract: Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.

Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a system includes an anesthetic agent reservoir, a pump fluidically coupled to the agent reservoir, an injector configured to receive pressurized anesthetic agent from the pump, a vaporizer comprising a heated chamber configured to receive and vaporize the anesthetic agent injected by the injector and supply a mix of the vaporized anesthetic agent and medical gas to a subject via a supply line, and a controller. The controller stores instructions executable to determine a concentration of the vaporized anesthetic agent in the mix and adjust one or more injector parameters based on a difference between the concentration of the vaporized anesthetic agent and a commanded concentration.
