Abstract: A first medical device for obstructive sleep apnea therapy includes therapy delivery circuitry coupled to a first set of electrodes implantable proximate to a first hypoglossal nerve within a tongue of the patient and configured to deliver a first electrical stimulation signal to the first hypoglossal nerve that causes the tongue of the patient to advance and includes information to communicate to a second medical device implantable within the head or neck of the patient and coupled to a second set of electrodes implantable proximate to a second hypoglossal nerve within the tongue of the patient; and sensing circuitry coupled to the first set of electrodes and configured to receive a second electrical stimulation signal, delivered to the second hypoglossal nerve by the second medical device, that includes information that the second medical device communicates to the first medical device.

Abstract: An air freshening device is made from a solution of a polymer and a fragrant material, which is applied to an air permeable substrate. A solid fragrant residue is formed on the substrate. A fragrant material diffuses from the residue for scenting flowing through and about the substrate. Means are provided for attaching the substrate to an air filter received in a forced air heating, ventilating, and cooling system.

Abstract: An air freshener device disposed in proximity to a ceiling fan by attachment to a pull chain of the ceiling fan for scenting air moved by the fan. The device receives a scented pad in a first dish that defines a pair of opposite slots for receiving links of the pull chain for securing the device in close proximity to the ceiling fan and for overlying the scented pad in the first dish. A second dish joins to the first dish by engaging a flange on the second dish to a groove in the first dish. The groove is defined by a rib which extends outwardly of a thinner distal portion of the skirt and a thicker portion of the skirt. The dishes define a plurality of vent openings for exposing the scented pad to air moved by the ceiling fan. A first tab extends outwardly of the first dish and a second tab extends outwardly of the second dish in partially overlapping relation, whereby the joined dishes are separated by twistingly moving the tabs in opposite directions.

Abstract: An air freshener apparatus having a recess defined by a tray, two sidewalls extending upwardly therefrom with overlapping flanges, and an upstanding end wall slidably received on a blade of a ceiling fan with a foam pad impregnated with a scent material received in the recess. Two hook-like arms extend outwardly from the tray for slidingly holding the air freshener apparatus on an upper surface of the fan blade.
