Abstract: A trigger generator for supplying a trigger signal to a medical device. The generator includes a respiratory signal device associated with the subject that generates a respiratory signal representing the flow of gas into and out of the subject's lungs during the subject's breathing cycle. A trigger generator integrates the respiratory signal and generates a trigger signal when the integrated respiratory signal has a value representing a selected point in the subject's breathing cycle.

Abstract: A hideaway tie rack is disclosed for a sliding door closet. The tie rack includes an elongated, cylindrical, hollow housing having an inner diameter of a first dimension, having a first open end and a second opposed end. The housing has an elongated, longitudinal slot extending axially along its surface, which has a circumferential width and which opens onto the first end of the housing. The housing is mounted on the back of the sliding door in a substantially horizontal orientation. The tie rack further includes an elongated cylindrical tube having an outer diameter of a second dimension which is less than the inner diameter of the housing. The tube has a first end and an opposed second end which slideably enters the first end of the housing. This enables the tube to be mounted within the hollow interior of the housing in axial sliding engagement with the housing. The tie rack still further includes a bar having a cross sectional dimension less than the circumferential width of the slot in the housing.
