Abstract: An air treatment device having a piezoelectric actuator powered by a transformer. The transformer has dual inputs comprising oppositely wound coils and input power signals 180 degrees out of phase. This arrangement provides a stronger drive signal to the actuator.

Abstract: A battery-powered cleaning implement for cleaning a target surface by using at least one of a motor-driven beater bar or motor-driven vacuum fan. The cleaning implement has a cutoff voltage below which the beater bar and/or said fan is/are no longer operable to clean. The cleaning implement has a control which reduces voltage provided by the battery/ies to the motor before the cutoff voltage is reached. The reduction in voltage provided to the beater bar and/or fan vacuum reduces the rotational velocity, providing an audible signal to a user that said voltage provided to said motor is being depleted.

Abstract: A delivery system and methods for generating droplets of liquid active materials, such as a perfume, air freshener, insecticide formulation, and volatile materials, to the atmosphere by means of a electromechanical transducer. The electromechanical transducer employs a first period of activation and a second period of deactivation to increase the distribution of volatile materials contained within the liquid active materials to the atmosphere and reduce the hedonic habituation of the user. The electromechanical transducer is configured to improve flow rate and decrease deposition of the droplets on to nearby surfaces.

Abstract: A product system comprises a package base unit and a package. The package base unit comprises a control element and a package interface operatively connected to the control element. The package comprises a package base interface, and a printed element. The printed element comprises a control circuit element and an output circuit element. Each of the control circuit element and the output circuit element are operatively connected to the package base interface.

Abstract: A device for emitting volatile compositions comprising a capillary element, a channel in fluid communication with the capillary element, an emitting orifice having a forward tilt from about +5 degrees to less than about +90 degrees, and a decoupled piezoelectric actuator for emitting the volatile composition through the emitting orifice. In some embodiments, the device is a plug-in air freshener and reduces surface deposition and improves scent noticeability through improved containment of perfumes during the rest period.

Abstract: An actuating device including a load and an integrated electronic control circuit comprising a microcontroller and at least one passive component. The microcontroller performs the dual function of providing a control signal to generate sufficient power to actuate a load and a drive signal to drive the load.

Abstract: A bed foundation may be retrofitted or otherwise converted in the field to include one or more additional function. In one illustrative embodiment, the bed foundation may be retrofitted or otherwise converted by incorporating a drop-in articulation unit. Such an articulation unit may permit a user to raise and/or lower the head of their bed. In some cases, a second articulation unit may be placed at the foot of a bed foundation to permit the user to independently raise and/or lower the head and the foot of their bed. In other illustrative embodiments, drop-in units may add other functions to existing bed foundations. In some cases, the bed foundation and/or drop-in units may be configured such that it can be easily shipped and assembled in the field by a user.

Abstract: An advertising display sign device particularly useful for real estate signs and similar displays. The device incorporates an inner frame in the general shape of a hollow rectangle, which is constructed with a length and height greater than its thickness. A narrow drawer is pivotally mounted near the bottom of the inner frame to tip outwardly through an opening in one of its minor sides; so that access may be made to the open top of the drawer. Because the pivot is on the forward edge of the drawer, the drawer returns to its closed position by gravity whenever it is released. Top, bottom and first and second end clamping members which fit together, are attached to the frame and extend a short space out from the opposing faces of the assembly. These clamping members hold in place first and second display panels, which are placed on both sides of the assembly to form an advertising surface.
