Abstract: A system and method for updating configurable hardware components of electronic systems wherein each configurable hardware component has a discoverable common memory region that includes specific identification information for the associated hardware component. Each common memory region can be surveyed in connection with generating a survey report that can be communicated to an external hardware management system that is remote from, and/or external to, the product. Using the identification information provided by the survey report, the external hardware management system can determine customized, and compatible, updated firmware for the electronic system, thereby minimizing the amount of firmware stored on the product. A variety of security measures can be also utilized to prevent unauthorized changes to the hardware components of the system.

Abstract: A percussor for respiratory percussion therapy, comprising a lightweight flexible cantilever handle and a soft elastomeric percussion cup secured to the distal end of the handle. The bell-shape of the percussion cup provides a highly effective percussion shock wave and sound, while accommodating a wide range of striking forces and angles relative to any desired body surface. A lip having a large surface area substantially avoids irritation, trauma and injury to the patient.
