Abstract: An aerobic spa system comprising a water source providing water, an ozone source providing ozone, an ozone introduction mechanism adapted to introduce at least some of the ozone into the water, an ozone saturation mechanism adapted to cause at least some of the ozone to be dissolved into the water, a substantially enclosed chamber receiving water containing dissolved ozone; and a user at least partially disposed inside the chamber who comes into contact with the water containing dissolved ozone.

Abstract: A plug is provided that includes a charging circuit and a supplemental memory and the plug body includes an outer profile that is a compact size. The plug allows for data from a battery powered device to be written to the supplemental memory for emergency access by the battery powered device. The plug provides for the backup from a battery powered device such as a cell phone or personal digital assistant of data such as telephone numbers, addresses, calendars, ring-tones, video or music files.

Abstract: A method and system for validating whether a battery charging device is authorized to charge a battery. An identifier from the battery charging device is received. It is evaluated whether the identifier meets at least one predetermined criteria. The battery charging device is allowed to charge the battery if the identifier meets the at least one predetermined criteria.

Abstract: A plug is provided that includes a charging circuit and a supplemental memory and the plug body includes an outer profile that is less than or equal to the outer dimension of a standard electrical outlet. The plug allows for data from a battery powered device to be written to the supplemental memory for emergency access by the battery powered device. The plug provides for the backup from a battery powered device such as a cell phone or personal digital assistant of data such as telephone numbers, addresses, calendars, ring-tones, video or music files.

Abstract: An optical package is provided having a diode mounted to a substrate enclosed by a housing which includes a bore for receiving an optical waveguide and a focusing element adjacent the bore. The bore and focusing element are aligned along a common optical axis. An alignment means is associated with the housing for aligning the substrate along the optical axis.

Abstract: A remote recording and playback system comprises a recording unit for recording analog data received virtually simultaneously over a plurality of analog input channels, and a playback unit for playing back said recorded analog data for a given one of the plurality of analog input channels. The recording unit sequentially scans the plurality of analog input channels in succession to derive respective analog data samples, converts the respective analog data samples to digital form, and stores the digital representations of the analog data samples in a random access memory. The playback unit accesses the random access memory in the recording unit, converts the digital representations derived therefrom to analog signals, and displays the previously recorded analog data, one channel at a time. The system is further characterized by the storage and retrieval of "drift" and D.C.
