Abstract: Disclosed herein are integrated circuit (IC) package lids with polymer features, as well as related methods and devices. For example, in some embodiments, an IC package may include a package substrate, a lid, and a die between the package substrate and the lid. A foot or rib of the lid may include a polymer material.

Abstract: A master system for providing a single interface between a user and service providers associated with the user's telematic devices. A storage module stores information, including serial numbers of the telematic devices, car information associated with the telematic devices, buyer information associated with the telematic devices, and location information associated with the telematic devices. An interface receives queries from the user and provides selected subsets of the information as responses to the user. An input-output holds multiple simultaneous communication sessions with service providers.

Abstract: An improved electrostatic precipitator system is provided for use in high-grease atmospheres in which the grease is electrically conductive. The precipitator includes high-voltage insulators that are both located in areas unlikely to accumulate electrically-conductive grease and that, in themselves, can operate in a high-voltage system without tracking, even when a certain amount of conductive grease has accumulated on the insulators' surfaces. In a multi-cell precipitator system, a high-voltage insulator is provided as part of a cell-to-cell assembly that receives high-voltage electricity on one side of its insulator, and conducts that electricity to its opposite side, and is placed in a specially-shaped cut-out in the bulkhead between the cell chambers, in which the cut-out is shaped so as to minimize the amount of grease that may accumulate upon the cell-to-cell assembly's insulators.

Abstract: An electrostatic air cleaner is disclosed for use in removing particulate matter from moving streams of air. A high voltage ionizer is used as a corona source to ionize the particulate matter as it approaches the air filter portion of the electrostatic air cleaner. The air filter uses reticulated polyether foam filter media for collecting the particulate matter, and the filter media is non-deliquescent, thus preventing the high-voltage electric field from being dissipated by imbedded water vapor, which is the cause of filter inefficiency in the prior art. In one embodiment, the air filter uses strips of conductive material raised to a very high DC voltage interleaved between strips of conductive material held to ground potential, and these strips are oriented so as to be parallel to the direction of the air flow through the air filter's foam filter media, thereby creating an electric field that is perpendicular to the direction of air flow.

Abstract: An electrostatic air cleaner is disclosed along with a method for removing particulate matter from moving streams of air. A high voltage ionizer is used as a corona source to ionize the particulate matter as it approaches the air filter portion of the electrostatic air cleaner. The air filter uses a pair of reticulated polyether foam filters for collecting the particulate matter. The foam filters are separated by a thin, grid-like layer of semiconductive material (carbon-impregnated polycarbonate) which is raised to a very high DC voltage. The foam filters are also surrounded by thin, grid-like layers of electrically conductive material which are held at ground potential, thus creating a high-voltage electric field through each of the foam filters. The polyether foam filter media is non-deliquescent, thus preventing the high-voltage electric field from being dissipated by such imbedded water vapor, which is the cause of filter inefficiency in the prior art.

Abstract: A conventional HEPA (high efficiency particulate air) filter is provided with a ionizer at its air inlet face to enhance its efficiency. The filter comprises a non-conductive fibrous filter medium sheet formed in a zig-zag or accordian fold. Within each fold of the filter medium is there located a conductive spacer so that the accordian folds are supported and substantially evenly spaced throughout the filter. By virtue of the accordian fold of the filter medium sheet, a series of spacers, forming a first set thereof, each has one of its longitudinal edges exposed at the air inlet face of the filter and the other of its longitudinal edges covered at the air discharge face of the filter. The remaining spacers constitute a second set thereof, each having one of its longitudinal edges exposed at the air discharge face of the filter and the other of its longitudinal edges covered at the air inlet face of the filter. The spacers of the first and second sets alternate, one adjacent the other.

Abstract: A method and apparatus for treating electrically charged airborne particles to reduce deposition of the particles on walls and other exposed surfaces in an enclosed area. Air containing positively charged particles exhausted from a first group of electrostatic precipitators is admixed with air containing negatively charged particles exhausted from a second group of electrostatic precipitators, the mixed air containing oppositely charged particles having less tendency to become deposited on walls and other surfaces in the enclosed area.

Abstract: The means and method for the cleaning and self-cleaning of an electrostatic precipitator is especially suited for adaptation to an electronic air cleaner comprised of an ionizer unit and a collecting cell unit adapted to be included in tandem within a suitable cabinet; means to bring air to be cleaned through these units are also provided, and these may or may not be an integral part of the cleaner. The ionizer unit may include support members for a plurality of ground plates between which are located ionizing wires which normally carry a low current but high voltage, preferably in the neighborhood of 10,000 to 14,000 volts. (Some electronic air cleaners, however, use voltages in the 5,000 to 9,000 volts range. This invention will also work effectively with them.
