Abstract: Example methods, apparatus, systems, and articles of manufacture to set a blue light cutoff time of an electronic device are disclosed herein. An example electronic device disclosed herein includes a display screen to emit first light in a first mode and second light in a second mode. The first light includes light having a characteristic that negatively affects sleep and the second light has less of the light having the characteristic that negatively affects sleep than the first light. The example electronic device also includes a display color adjuster to set a blue light cutoff time based on sleep data received from a sleep tracking device, and the display is to switch from the first mode to the second mode at the blue light cutoff time.

Abstract: CuO—ZnO—CeO2 catalyst and aged CuO—ZnO catalyst catalytically active for low temperature oxidation of carbon monoxide. The catalysts are co-precipitated, filtered, washed, dried, and calcined. The catalysts can be incorporated into a component of a cigarette or can be used to reduce the concentration of carbon monoxide from a vehicle exhaust emission, a gas used in a laser, a gas used in a fuel cell and/or ambient air undergoing air filtration.

Abstract: A method for forming a copper oxide catalyst includes forming a precipitate of copper hydroxide from a copper salt solution; forming dried particles of copper hydroxide by drying the precipitate at a temperature of less than 30° C.; heating the copper hydroxide particles to form copper oxide; and activating the copper oxide. The copper oxide catalyst includes particles of copper oxide. Copper oxide catalyst particles can preferably include a metastable form of copper oxide. The copper oxide catalyst particles are useful for low-temperature and near-ambient temperature catalysis and/or oxidation of carbon monoxide to carbon dioxide.

Abstract: A reactor produces a surface corona for emitting UV light and for the production of ozone by passing air or oxygen through the surface corona. The emitted UV light activates a photocatalyst coated on a surface facing a surface with embedded electrodes which generate the surface corona. The photocatalyst is a thin film of nanoparticle TiO2 with primary particle size of 0.02 to 0.2 ?m was deposited on a substrate by a flame aerosol method. The method combines ozonation and photocatalysis to provide effective and efficient oxidation of alcohols and hydrocarbons to value added products. The method can also be used for air and water cleaning.

Abstract: A catalyst comprising gold nandots on cerium oxide, catalytically active for oxidation of carbon monoxide at room temperature. The catalyst is prepared by deposition-precipitation followed by aging or ultrasound treatment.

Abstract: A protocol for communication between devices connected via a bus having three handshake lines and at least one data line. A first device controls two of the three handshake lines, and a second device controls the third. The first device mixes toggling of the first and second handshake lines in a pattern which identifies a type of information packet. The second device polls the first and second handshake lines, and from the toggling pattern identifies the packet type. Once identified, the packet is transmitted according to a predefined format for the type. Typically, transmission of information is completed asynchronously using the handshake lines to carry request and acknowledge signals. In one embodiment, the protocol is implemented in a virtual reality system having a video game console as a first device and a head mounted display as the second device.
