Abstract: Various implementations include neonatal transport apparatuses and systems employing such apparatuses. In one particular implementation, an apparatus includes: an isolation stage; a first mount on a first portion of the isolation stage, the first mount configured to engage a mounting frame of a neonatal transport unit; a second mount on a second portion of the isolation stage, the second mount configured to engage a stretcher; and a stabilizing coupler extending from the second portion of the isolation stage, the stabilizing coupler positioned to directly couple the isolation stage with a floor underlying the stretcher.

Abstract: An active vibration isolation system for isolating a suspended platform from vibration input to the vibration isolation system base includes an exoskeleton, a rotary actuator, and a drive mechanism separate from the exoskeleton for providing force output from the rotary actuator to the suspended plant. The rotary actuator may include inner and outer rotors which rotate relative to each other. The rotary actuator may be free to translate relative to the vibration isolation system base and the suspended platform, and both the inner and outer rotors may be free to rotate relative to the exoskeleton.

Abstract: A loudspeaker includes a first electro-acoustic transducer, a horn acoustically coupled to the first electro-acoustic transducer, and a first acoustic leak that is acoustically coupled to the horn. The first acoustic leak is positioned so as to reduce a peak in a frequency response of the loudspeaker at the targeted frequency without removing the targeted frequency from the output of the loudspeaker.

Abstract: Various aspects include audio devices with a capacitive sensing interface along a compound curved wall. Some aspects of the disclosure relate to wearable audio devices with a capacitive sensing interface and a flexible printed circuit board (PCB) for detecting a touch command at the interface. In certain cases, the flexible PCB has at least one slit for conforming to the compound curve of the wall. In additional implementations, the inner surface of the wall is faceted and the flexible PCB conforms to the facets in the wall.

Abstract: A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. The combined motion of the vehicle relative to the earth and the seat relative to the vehicle results in motion of the seat moving about a virtual pivot point. A user control is provided for adjustment of the location of the virtual pivot point.

Abstract: An apparatus includes a frame and a surround element that couples a diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The surround element includes a half-roll element having a concave apparent area and a convex apparent area. The concave and the convex apparent areas are disproportionate. Another apparatus includes a diaphragm, a frame, and a surround element that couples the diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The surround element includes a half-roll element having a horizontal span and a free-length. A ratio of the horizontal span to the free-length is constant throughout the half-roll element. According to another example, an apparatus includes a landing and a half-roll element adjacent the landing. The half-roll element includes an inner portion, an outer portion having a variable thickness, and a transition portion located between the inner portion and the outer portion.

Abstract: A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. One or more sensors can each measure an aspect of motion. A processor can (i) receive input from each of the one or more sensors, (ii) determine from this input a measure of rotation of the vehicle away from a nominal, level horizontal orientation, and (iii) utilize the input to determine a desired rotation of the seat. An angle that the seat has been rotated away from a nominal, level orientation is more than insubstantially larger than an angle that the vehicle has rotated away from a nominal, level horizontal orientation.

Abstract: An audio system includes a housing that defines an acoustic enclosure, an acoustic driver supported by the housing and arranged to radiate acoustic energy from a front surface of the housing, an acoustic exit located in a rear surface of the housing, opposite the front surface. The acoustic exit has a shape that facilitates a grasping of the housing with a plurality of fingers and the thumb from a single human hand, such that at the plurality of fingers or the thumb can be inserted into the exit while the plurality of fingers or the thumb of the same hand can rest on a top surface of the housing.

Abstract: A moving magnet motor with a stator comprising first and second spaced coil-wound cores that each have a width, the cores separated by an elongated gap, and an elongated magnet located at least in part in the gap and lying generally along a motor depth axis that is in the gap and is generally uniformly offset from the cores, where the magnet has poles. The motor has a width axis that is perpendicular to the depth axis and is generally uniformly offset from the cores. The magnet has a width along the motor width axis and the cores each have a width along the motor width axis. Along the motor depth axis the ratio of the width of the magnet or a pole of the magnet to the width of a core varies.
