Abstract: A method and apparatus as disclosed in the present disclosure may provide supercooling functionality for a wide range of perishable items. Supercooling may be accomplished by using at least one of magnetic fields, electric fields, displacement current, or a combination thereof. Supercooling of the perishable items may be accomplished by selecting specific parameters (e.g., power amplitudes, waveforms, frequencies, and duty cycles) of the least one of magnetic fields, electric fields, or displacement current to drive the electronics that create these energies. Different perishable items may require different combinations of these parameters to achieve optimal supercooling effects. Different combinations of the parameters may be applied to different perishable items so that different type of perishable items can be supercooled concurrently or simultaneously. Further, the different combinations of the parameters may be applied at any time relative to one another.

Abstract: A kit for attenuation of noise includes a noise source audio transducer, two ear pieces, and a control unit. The two ear pieces have respective resilient bodies that engage outer portions of ear canals of respective ears of a user while respective in-ear transducers of the two ear pieces are respectively positioned in inner portions of the ear canals. The respective in-ear transducers detect discrepancies (e.g., incomplete superpositioning) between the noise and the anti-noise. The respective in-ear transducers optionally detect respective secondary path effects in the ear canals. The noise source audio transducer detects noise generated by a noise source (e.g., snoring noise). The control unit configures an adaptive filter based at least in part on an error signal, and optionally based in part on secondary path effects. The control unit generates signals representative of anti-noise. The two ear pieces produce the anti-noise responsive to the signals.

Abstract: A method and system for dynamically manipulating values associated with graphical elements displayed within a graphic interface of a data-processing system. Initially a pointer element associated with a pointing device is displayed within the graphic interface, such that the pointer element is capable of movement in multiple directions in response to movement of the pointing device. A trackslide element and a moveable slider are displayed within the graphic interface. The moveable slider permits users to dynamically decrease or increase values associated with the trackslide element, such that the moveable slider is constrained to move only in a first direction along the trackslide element. The pointer element is then graphically attached to the moveable slider.
