Abstract:
A system for improved manual welding is provided. The system includes a novel nozzle for maintaining fixed electrode-work piece distance, sensors such as optical, temperature, ultrasound and the like for providing feedback on weld quality, and indicators such as a video screen indicating actual vs. desired weld characteristics (such as speed, size, position, and the like). Furthermore actuators in the device allow for control over movement either perpendicular to the weld seam, parallel to it, or both. For example an eccentric axis allows for automation of the welding weave motion.
Abstract:
Embodiments of the present invention provide a variety of devices, apparatuses, system and methods for dosage or dispensing management for liquids or fluids. In one embodiment the dosing device includes a dosage receptacle consisting of container of a fixed size that can hold a single dose of dispensing container contents. The dosing device includes a sealing member that allows the container contents to enter the dosage receptacle when the container is shaken or turned, yet closes the entrance to the dosage receptacle when the container is substantially in the upright position.
Abstract:
A method of rehabilitation using an actuator type that includes a movement mechanism capable of applying a force that interacts with a motion of a patient's limb in a volume of at least 30 cm in diameter, in at least three degrees of freedom of motion of the actuator and capable of preventing substantial motion in any point in any direction in said volume, comprising: exercising a patient at a first place of rehabilitation selected from a bed, a wheel-chair, a clinic and a home, using an actuator of said actuator type which interacts with a motion of said patient; and second exercising said patient at a second place of rehabilitation selected from a bed, a wheel-chair, a clinic and a home using a second actuator of said actuator type which interacts with a motion of said patient; wherein said first exercising and said second exercising utilize a same movement mechanism design for moving the actuators.
Abstract:
A controlled descent device adapted for lowering people from an elevated position to a lowered position a predetermined distance therefrom at a constant velocity, the descent device comprising an axle, a descent unit mounted on the axle and adapted for rotational motion therearound, and a braking system adapted to restrict rotational motion of the axle to a constant rotational velocity; the descent unit comprising a cylindrical member, a cable wound around the cylindrical member adapted for suspending the people during said lowering, an engagement mechanism mounted on the cylindrical member, and a rotation restriction mechanism.

Abstract:
The invention relates to a rehabilitation device which guides a patient to perform a motion with a correct spatial trajectory, by the device applying one or more pushing, assisting, reminding, responding and/or resisting forces during a motion (or intent to move) by the patient. The forces are applied by an actuator, for example, a robotic articulated arm or a spherically jointed lever. The applied forces act as a force fields, optionally continuous, which impeded and/or guides a patient. The device can be programmable with various trajectories (paths and/or velocities) and/or forces. The forces at one point in the trajectory can vary responsive to an actual trajectory by the patient and/or responsive to a rehabilitation plan and/or improvement of the patient. The device can learn a motion entered by a physiotherapist and replay it for the patient.
