Abstract: A method for compensating torsional loads applied to a shaft coupled to a main engine, comprising measuring values indicative of torsional loads applied on the shaft or power demand from the main engine; computing from the values the torsional load over time and a parameter indicative of a cycle; after measuring the group of values, measuring a subsequent value indicative of torsional loads applied on the shaft, and applying a compensating moment or load in a direction determined by whether the subsequent value is greater than or smaller than the value representing the torsional load over time. The direction is a torque direction applied to the shaft by the main engine or the opposite direction.

Abstract: A system for alleviating variations in torsional loads applied to a shaft coupled to a main engine of a marine vessel, said shaft is coupled to a propeller of the marine vessel, the system comprising an electric motor-generator configured to provide power to the shaft or take out power from the shaft; a controller coupled to the electric motor-generator said controller is configured to execute instructions, comprising: measuring a group of values that are indicative of torsional loads applied on a shaft of the marine vessel over time; creating a time-based series of values that represent a predictive time-based torsional loads on the marine vessel; collecting readings indicative of power provided by a main engine of the marine vessel; computing an intervention time series of power values to be outputted by the electric motor-generator; wherein the electrical power outputs the intervention time series values of power to the shaft.

Abstract: Systems, methods and devices, for stimulating one or more esophageal muscle contractions are provided. The system, methods, and devices may be designed to evoke motion and/or restore function in one or more organs that are located distal to the lower esophageal sphincter. A controller and a generator may be used to transmit signals to one or more electrodes in a tube placed in a patient's GI tract. In some aspect, the generator is configures to generate a series of pulses for one or more periods of time. In some aspects, a preliminary pulse is transmitted to narrow and esophageal portion such that an esophageal wall is in contact with at least one electrode thus lowering the nominal stimulation threshold.

Abstract: Wheel with an in-wheel suspension system, and suspension member thereof. Wheel includes: stationary member including an axis, rotary member rotatable about the axis, and selective suspension system. The selective suspension system has at least one suspension member positioned between the stationary member and the rotary member, thereby providing a fixed distance therebetween, and retains the fixed distance when stressed up to a threshold value, and recoverably alters the fixed distance when stressed over the threshold value. The suspension member includes: cylindrical housing, piston slidably movable in the cylindrical housing, and compression spring whose first end is connected to the piston and second end is connected to the housing. The compression spring, when fully relaxed or compressed under the threshold value, maintains the housing and piston at a normally fixed distance. Applicable to wheelchairs and bicycles, among other self-propelled and powered vehicles.

Abstract: A wheel connectable to a vehicle. The wheel includes a stationary member having an axis, a rotary member rotatable about the axis, and at least one support member positioned between the stationary member and the rotary member, thereby providing a normally fixed distance therebetween. The support member is adapted to retain the distance when stressed up to a threshold value and to recoverably alter the distance when stressed over the threshold value.

Abstract: A wheel with a suspension system being connectable to a vehicle, like a wheel chair. The wheel includes a hub and a rim rotatable about the axle of the hub. Between the hub and the rim, a number of support members is located. The support members are adapted to retain the distance when stressed up to a threshold value and recoverly alter the distanced when stressed over this threshold value. Exemplary support members are spring elements, damping strokes by compression if the support member is compressed or elongated. The spring elements may be preloaded.
