Abstract: Example motor assemblies for architectural coverings are described herein. An example architectural covering assembly includes an architectural covering movable between an upper limit position, a lower limit position, and a transition limit position between the upper limit position and the lower limit position. The example architectural covering assembly also includes a motor, a consumer touchpoint, and an architectural covering controller. In response to detecting a first gesture at the consumer touchpoint, the architectural covering controller is to activate the motor to move the architectural covering to the transition limit position and stop, and in response to detecting a second gesture at the consumer touchpoint, different from the first gesture, the architectural covering controller is to activate the motor to move the architectural covering through the transition limit position and to the upper limit position or the lower limit position.

Abstract: A method for detecting Chiari malformations. The method generally comprises positioning a patient in an upright orientation in a patient-receiving space of a magnetic resonance imaging apparatus and acquiring images of the patient's cerebellum and brainstem in the upright orientation. The method further comprises positioning the patient in a recumbent orientation in the patient-receiving space of the magnetic resonance imaging apparatus and acquiring images of the patient's cerebellum and brainstem in the recumbent orientation.
