Abstract: Among other things, a rowing exercise machine includes a movable inertial element, an eddy current brake coupled to the movable inertial element, a rowing grip coupled to the movable inertial element, and control circuitry coupled to the eddy current brake to cause a resistance to motion of the rowing grip during part of a rowing stroke. The resistance to motion of the rowing grip during the drive phase of the rowing stroke conforms to a target feel for a rower. The target feel corresponds to a feel for a rower of a target other rowing exercise machine or other target feel of interest.

Abstract: The present disclosure relates to a dose detection system for use with a medication delivery device in which a dose setting member rotates relative to an actuator during dose delivery. The dose detection system includes a module which is removably attached to the medication delivery device. The module includes a rotation sensor attached to the actuator during dose delivery. A sensed element is attached to the dose setting member and includes surface features detectable by the rotation sensor. The rotation sensor comprises a following member including a contact portion resting against and spring-biased in the direction of the surface features. The contact surface is positioned to move over the surface features during rotation of the sensed element, and the rotation sensor is responsive to the movement of the contact portion over the surface features to detect the rotation of the dose setting member.

Abstract: A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer. The primary condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a condensing liquid, to form a bio-oil component mixture having multiple separated phases. At least a portion of the condensing liquid includes a component that is extracted as a separated stable phase from a second bio-oil component mixture resulting from a prior pyrolysis cycle.

Abstract: A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and includes an input to receive pyrolytic vapors from the pyrolyzer and a solvent. The condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with the solvent to form a condensed liquid that exits the primary condenser via an output. A capture vessel receives the condensed liquid from the condenser output. A recirculator couples the capture vessel to the primary condenser input and is configured to receive the condensed liquid from the primary condenser, and to provide at least a portion of the condensed liquid as the solvent in the primary condenser. The solvent from the bio-oil component/solvent mixture is then extracted in a solvent extraction system and returned to the quenching system.

Abstract: A fast pyrolizer includes an elongated tubular housing having a feed inlet to receive material, an outlet, and a flow path. The flow path has an internal contact surface extending from the inlet to the outlet. The inlet is to be oriented to a non-vertical relative elevation with respect to the outlet. At least a portion of the internal contact surface directly contacts the material. A heater heats the internal contact surface such that the material is heated via direct thermal transfer from the internal contact surface.

Abstract: The present invention provides a building material derived from straw, such as rice straw, that has significantly improved fire-resistance properties over traditional cellulose-based materials. In one embodiment, the invention provides a method of fabricating a board from milled rice straw. The milled rice straw is blended with a binder to form a mixture. The mixture is then formed into a mat with sufficient size to achieve a predetermined board thickness and density. The mat is then pressed into the board. In another embodiment, the present invention provides a fire resistant board that includes milled rice straw, a resin binder, and a fire retardant material such as an organic phosphate, zinc borate, aluminum trihydrate, sodium silicate, or even rice hulls.
