Title: Reduced-emissions combustion utilizing multiple-component metallic combustion catalyst
Inventor: SPRAGUE BARRY N
IPC: F02M27/02
Filed: 2003-02-03
Granted: 2010-05-04
Abstract: Residual fuels, as well as lighter distillate fuels, are combusted with greater efficiency by utilizing low concentrations of specific bimetallic or trimetallic fuel-borne catalysts. The catalysts reduce fouling of heat transfer surfaces by unburned carbon while limiting the amount of secondary additive ash which may itself cause overloading of particulate collector devices or emissions of toxic ultra fine particles when used in forms and quantities typically employed. By utilizing a fuel containing a fuel-soluble catalyst comprised of platinum and at least one additional metal comprising cerium and/or iron, production of pollutants of the type generated by incomplete combustion is reduced. Ultra low levels of nontoxic metal combustion catalysts are able to be employed for improved heat recovery and lower emissions of regulated pollutants.

Abstract: Improved techniques to control utilization of accessory devices with electronic devices are disclosed. The improved techniques can use cryptographic approaches to authenticate electronic devices, namely, electronic devices that interconnect and communicate with one another. One aspect pertains to techniques for authenticating an electronic device, such as an accessory device. Another aspect pertains to provisioning software features (e.g., functions) by or for an electronic device (e.g., a host device).  Different electronic devices can, for example, be provisioned differently depending on different degrees or levels of authentication, or depending on manufacturer or product basis. Still another aspect pertains to using an accessory (or adapter) to convert a peripheral device (e.g., USB device) into a host device (e.g., USB host). The improved techniques are particularly well suited for electronic devices, such as media devices, that can receive accessory devices. One example of a media device is a media player, such as a hand-held media player (e.g., music player), that can present (e.g., play) media items (or media assets).
