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: Two-component polycarbonate-based composite products are contemplated in which the composite is formed as the cured reaction product of a polycarbonate polyurethane dispersed within an aqueous colloid along with a coalescent agent, a secondary polymer additive dispersed within the aqueous colloid, and a secondary polymer crosslinker. The aqueous colloidal dispersion may be applied as a coating to a surface that is intended to be coated and subsequently permitted to react and dry, resulting in the formation of a coating at the location at which it is applied. The composite product may be further formulated with additional constituents to be optically clear, glossy, and/or pigmented.

Abstract: A method of treating brines (10) comprising the steps of: pre-cooling the brines using a stream medium before further cooling the brines using a refrigerant. This further cooling of the brines continues until a first temperature equal to a eutectic freezing point of a mineral salt suspended in the brines is reached, such that the brines are transformed into an ice slurry. The ice is then separated from the ice slurry for use as part of the pre-cooling step. The remainder of the ice slurry is filtered to recover crystallised mineral salts suspended therein. A system for performing the method is also described.
