Abstract: An electrostatic air cleaner for use in motor vehicles has a housing enclosing a fan, a charcoal filter and an electrostatic air cleaning element. The electrostatic element and the filter are removable through a top cover for cleaning purposes. A telescoping rod extends through a ring on a top surface of the housing cover and includes frictional pads engaged with opposite side walls within a vehicle interior for securing the electrostatic air cleaner adjacent an interior vehicle ceiling. The electrostatic cleaner may be powered by an adaptor connected to a cord and engaged with a vehicle cigarette lighter.

Abstract: A microprocessor system wherein a plurality of programs shares a single central processing unit. A first subsystem includes a memory having a program counter for indicating the point of execution of a program and a data pointer indicating the location in memory of data processed by the program in execution. At least one other subsystem includes a memory having a program counter for indicating the point of execution of a program and a data pointer indicating the location in memory of data being processed by the program in execution in that subsystem. A console control module is interconnected with the system data bus and the first and second subsystems, and controls operation of the central processing unit with each subsystem. The subsystem not connected to the central processing unit indicates the point of interruption of program execution with the program counter and indicates the location of data being processed by the interrupted program.
