Abstract: A gyroscopic roll stabilizer for a boat includes an enclosure mounted to a gimbal for rotation about a gimbal axis and configured to maintain a below-ambient pressure, and a flywheel assembly including a flywheel and flywheel shaft, with the flywheel assembly rotatably mounted inside the enclosure for rotation about a flywheel axis. The gyroscopic roll stabilizer also includes a motor operative to rotate the flywheel assembly and mounted in a boss that is integrally formed in the enclosure. A motor cooling circuit is configured to transfer heat away from the motor. The motor cooling circuit has a closed fluid pathway for recirculating cooling fluid therein. The fluid pathway extends through the boss so that the cooling fluid circulates through the boss around the motor. The gyroscopic roll stabilizer is configured to transfer heat away from the motor to the cooling fluid. Related methods are also disclosed.

Abstract: A system and method for graphically indicating patient information. The invention includes a representative image of the patient with icons to indicate or inform a health care worker of the condition of the patient. Each icon in a set of icons represents a condition available for use in describing the condition of a particular patient. Each icon is located at a predetermined position of the image in each implementation of the invention. After a user creates an image with icons selected for a particular patient, a fixed representation of the image is created. The fixed representation of the image (e.g., on a sheet of paper) is placed proximal to the patient (e.g., bedside) for visual conveyance of the patient's condition.
