Abstract: A blocking element is disclosed for blocking the movement of a handle or a switching lever of an electrical switch. In at least one embodiment, the blocking element is switchable between at least two positions. In the first position, the blocking element can block the movement of the handle or of the switching lever and, in the second position, the blocking element cannot block the movement of the handle or of the switching lever.

Abstract: The present invention provides an apparatus for the supply of air for the treatment of sleep apnea. The apparatus of the present invention includes a motor and a fan unit. The motor and fan unit are enclosed in an inner case of flexible foam plastics material. The inner case is configured to contain the motor and the fan unit, and the inner case 48 is generally biased against the motor and the fan unit. The inner case is, in turn, contained within an intermediate case made of rigid material. The intermediate case conforms to and is substantially filled by the inner case such that the inner case is generally biased against the intermediate case. Finally, the intermediate case is contained within an outer case of rigid material. The outer case surrounds the intermediate case. The outer case is generally set apart from the intermediate case so that there is a gap between the intermediate case and the outer case.

Abstract: An improved liner (i.e., prosthetic liner) for covering a residual limb of an amputee is provided. According to one exemplary embodiment, the liner includes a fabric liner body that is formed of at least two fabric pieces and a stretch limiting element that is incorporated into an exterior surface of the distal end of the fabric liner body for reinforcement of the liner's distal end and for limiting stresses associated with distal end elongation. For example, the stretch limiting element can be in the form of a coating of a material that has limited flexibility and is integrally adhered to the outer surface of the fabric liner body such that the material seeps into the interior of the fabric liner body and optionally into any seams.

Abstract: Method and apparatus to automatically monitor and control a perfusion hyperthermia treatment using a system including one or more programmed computers, and mechanical and sensor subsystems. The system includes a fluid path between a patient and an external fluid-treatment subsystem, wherein control of the external fluid-treatment subsystem includes feedback from sensors coupled to the patient. The resulting integrated system provides automated monitoring and control of the patient, the external fluid-treatment subsystem, and the treatment. In one embodiment, the fluid passing between the patient and the external fluid-treatment subsystem is blood. In one embodiment, an apparatus and method are provided for using a computerized system for a perfusion hyper/hypothermia treatment of a patient which obtains a body fluid having a temperature. A plurality of temperature signals representative of temperatures at each of a plurality of patient locations on or within the patient are coupled to the computer system.

Abstract: A control for a window operator is operable to control incremental movement of a window. The control includes means for developing a command to selectively move the window in a direction to an open or closed position, and means for determining when a plurality of motor drives have moved the window a preselected incremental distance. Means are coupled to the developing means and the determining means for energizing each of the motor drives if a command is developed, until the motor drives have moved the window the preselected incremental distance and thereafter deenergizing the motor drives until another command is received to move the window a subsequent incremental distance in the selected direction.
