Abstract: Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

Abstract: A wireless account management system including an account manager system, customer systems, and carrier systems linked by the Internet. The account manager system includes a management tool adapted with a data loader for receiving billing and usage data from the carrier systems and converting it to a single format for storage in a management database. The data loader allows carrier system data having a similar format but differing data arrangement, carrier system data having different formats, and carrier system data having a format not readily parsed all to be processed and parsed into files having a single format. Plaintext files are parsed by a text parser and carrier-specific files are parsed by modules provided to interpret corresponding carrier's bills. An optimization engine uses usage reports created from call detail records, lists of available service plans, and customer-provided and carrier-specific criteria to create plan recommendations for each wireless device.
