Abstract: A door operator for controlling operation of a door, the door operator having a motor to open the door against a spring force, the door operator further comprising a door position sensor for transmitting a signal indicative of door position; and among other things, calculates a door moment of inertia based on a net torque and the time for the door to reach a predetermined angle from the closed position. Also provided is a door operator that compares door speed to a desired door speed based on a door speed-position profile and generates a door speed error signal and minimizes the door speed error signal by adjusting the braking load resulting from charging a chargeable battery using the motor as a generator.

Abstract: A caster wheel, comprising a wheel contained between covers; a drive assembly connected to the covers; and a locking assembly connected to the drive assembly, the locking assembly applying pressure to a surface of the wheel under action of the drive assembly, thereby controlling a rotation of the wheel around both a vertical and horizontal axis.

Abstract: A door operator assembly, comprising an operator unit mounted to a first position, relative to the door, by a first mounting bracket; and an arm linkage connecting the operator unit and a second position, relative to the door; the arm linkage being mounted at the second position by a second mounting bracket.

Abstract: A brassiere comprises a pair of cups for supporting and shaping the breasts of the wearer. The cups are connected by connecting structure. A side panel is attached to each cup. Each side panel has a surface for contacting the wearer. The side panels are adapted to apply substantially uniform pressure to the wearer across the surface in contact with the wearer for the purpose of increasing comfort and reducing unsightly bulging of tissue of the wearer's sides and back.
