Abstract: Mattress assemblies include integrated handles, wherein the integrated handles are formed in the border panel about the mattress perimeter from excess material thereof.

Abstract: A mattress assembly generally includes a tension adjustable and stretchable fabric panel coupled to a rail system. Axial tension of the stretchable fabric panel can be adjusted to change a firmness property associated with the mattress assembly.

Abstract: A dental flossing device comprising a first body circumscribing a void adapted to receive one or more fingers of a user, an outward-facing surface, opposite from the void, having a first segment comprising at least one pair of cleats arranged to define a circumferential groove for receiving and carrying one or more revolutions of the dental floss formed by wrapping the dental floss along the circumferential groove. A second segment of the outward-facing surface includes a fastener comprising a depression, a crown with a base wall and a niche in the base wall, and a pedestal that connects the base wall of the crown to a floor of the depression. The base wall, niche and the pedestal are configured to provide a space located between the floor of the depression and the base wall to receive and secure a free end of the dental floss.

Abstract: A single stage, single switch, input-output isolated converter configuration which uses a hybrid combination of forward and flyback converters is disclosed. The converter operates at a high input power factor with a regulated DC output voltage. It makes use of a novel control scheme utilizing duty cycle control at two discrete operating frequencies. Although the invention employs two frequencies, it does not use a continuous frequency variation. This configuration has the advantage of reduced peak current stresses on the components and is specifically suited for ‘buck’ applications where low DC output voltages (e.g. 24V, 48V) are needed. This configuration will be of specific interest to industries associated with battery charging and uninterruptible power supply (UPS) systems.

Abstract: A group organizational system operational as a computer program on a computer network. The computer network provides communication between a host server and a plurality of remote individual users. The group organizational system includes an organization database, a registrant database and a roster database. The organization database includes information relevant to an organization and predetermined registration qualifications. The registrant database is in communication with the remote users and the host server. The registrant database receives registration information from the remote users. The roster database is in communication with the host server. The host server includes a registration generation program for comparing the registration information of the remote users with the predetermined registration qualifications to determine whether a remote user qualifies as member of the organization.
