Abstract: A motorized drapery system having an elongated rotating drive element that has a non-circular cross-sectional shape such as square, rectangular, trapezoidal, cross shaped or any other non-circular shape that is twisted. In one arrangement the drive element is twisted in one direction along its entire length. In another arrangement the drive element is twisted in one direction in a first section and twisted in an opposite direction in a second section thereby providing a center opening/center closing drapery. A plurality of rings are positioned around the drive element including at least one driver ring that includes a feature that connects to the drive element and is configured to facilitate movement along the drive element, and a plurality of idler rings that are configured to slide along the drive element. A curtain is connected to the rings and opens and closes as the rings move along the drive element.

Abstract: Techniques for identifying individual target sites for application of transcranial magnetic stimulation (TMS) to a brain of a patient for treatment of neurological and psychiatric disorders. The identification of the target TMS stimulation sites may be based on using functional connectivity magnetic resonance imaging (fMRI) to determine cortex regions of the brain that are functionally connected to other regions of the brain that may be stimulated to decrease symptoms of depression and other disorders. For example, target stimulation sites may be identified in the left dorsolateral prefrontal cortex (DLPFC) to remotely modulate the activity in a subgenual cingulate region and other limbic regions functionally connected with the DLPFC. TMS may be applied to the patient's head at the identified target TMS sites to treat depression and other neurological and psychiatric disorders.
