Abstract: An eddy current non-destructive evaluation system for an electrode film material includes: at least one control module configured to generate a transmission signal; and a first pair of coils. The first pair of coils includes: a first coil disposed adjacent the electrode film material and configured to operate in a transmit mode, and, based on the transmission signal, to generate an electromagnetic field that passes through the electrode film material; and a second coil disposed adjacent and on an opposite side of the electrode film material as the first coil and configured to operate in a receive mode. The second coil is configured to generate a electromagnetic field voltage based on the electromagnetic field. The at least one control module is configured, based on the electromagnetic field voltage, to at least one of determine a thickness of the electrode film material and detect a defect of the electrode film material.

Abstract: A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface. Adjustments to inflation or deflation of one or more bladders are made to achieve a desired immersion amount within a tolerance range between upper and lower TOF thresholds.

Abstract: A method for calibrating a 3D printer includes the steps of providing information obtained in a factory calibration indicating a center of an inner diameter of a tip orifice in a metal extrusion nozzle and a center of a tip surface for the nozzle and inductively sensing the nozzle with an eddy current sensor when secured to a print head on a gantry or robotic arm of the 3D printer to identify a sensed location of the center of the tip surface of the nozzle. The method includes determining a location of the center of the inner diameter of the tip orifice on the nozzle on the print head and utilizing the provided information to locate the center of the inner diameter of the tip orifice.
