Abstract: A turbocharger control system for a high-pressure turbocharger and a low-pressure turbocharger includes a turbo mode determination module and a transition control module. The turbo mode determination module determines a transition from a dual turbo mode to a single turbo mode. The high-pressure turbocharger is active in the dual turbo mode and idle in the single turbo mode. The transition control module determines a turbine efficiency of the high-pressure turbocharger and controls the high-pressure turbocharger during the transition based on a predetermined maximum turbine efficiency equation.

Abstract: A transparent microporous optical contact lens having a lens body including a contact surface and a frontal surface. A plurality of micro-passageways extend through the lens body between the contact surface and the frontal surface. Each of the micro passageways has a pair of generally cylindrical inwardly converging end portions which communicate with a diametrically enlarged generally spherical intermediate portion located between said end portions.

Abstract: A non-tracking spherical solar energy collector including a fluid lense and an absorber having an energy absorbing surface within the focal region of the lense. The minimal surface area of the absorber required for efficient solar energy collection is determined by ray tracing techniques utilizing known positions of the sun during days of winter and summer solstice.

Abstract: Compounds having the general formula: ##SPC1##Wherein R.sup.1 and R.sup.2 represent hydrogen, halogen, lower alkyl, lower alkoxy, or nitro, and wherein R.sup.1 and R.sup.2 may be the same or different. R.sup.3 may be hydrogen or lower alkyl, and X and Y may be one or two. They have been found to be useful sedative type depressants of the central nervous system.Most of the compounds having the general formula indicated above are new but others such as 2,3-dihydrospiro[naphthalene-1(4H),3'-piperidine]-2',4,6'-trione which has useful sedative properties have been reported in the literature.
