Abstract: A restaurant greeter method includes storing a plurality of greeting messages in memory of a greeter, associating at least one greeting message with a specific time of day, playing the at least one greeting message from the memory of the greeter upon detection of an individual at the specific time of day, and playing a different message if an individual is detected and the time is not at the specific time of day. Messages and other data can be downloaded from a remote server or loaded at the greeter. The greeter can be interrupted by a base station. Each of the messages can be temporally assigned. In an example, a bypass circuit selectively connects the greeter intermediate to the menu post and the base station.

Abstract: An emissions control system is disclosed. The emissions control system may have a first exhaust treatment device. The emissions control system may also have an end cap defining a mixing chamber connected to an end of the first exhaust treatment device. The mixing chamber may be configured to promote mixing between a flow of exhaust received from the first exhaust treatment device and a reductant. The emissions control system may further have a second exhaust treatment device configured to receive the flow of exhaust and reductant after it passes through the mixing chamber.

Abstract: An exhaust treatment system includes an oxidation device having a plurality of channels through which a flow of exhaust flows. A first portion of the channels of the oxidation device are coated with catalytic material for converting NO to NO2 and a second portion of the channels are uncoated with the catalytic material. The exhaust treatment system also includes a selective catalytic reduction device disposed downstream from the oxidation device. The selective catalytic reduction device is configured to receive the flow of exhaust passing through the oxidation device.

Abstract: Ultrashort laser pulses are used to induce photodisruptive breakdown in vasculature in an animal to controllably produce hemorrhage, thrombosis or breach of blood-brain barrier in individual, specifically targeted blood vessels. Damage is limited to the targeted vessels such that neighboring vessels exhibit no signs of vascular damage, including vessels directly above or below the targeted vessel. Ultrashort laser pulses of lower energy are also used to observe and quantify the baseline and altered states of blood flow. Observation and measurement may be performed (1) by TPLSM, OCT or other known techniques, providing a real-time, in vivo model for the dynamics and effects of vascular injury.

Abstract: A gas collector hood is located close to the mouth of a converter vessel and has a diameter which is not much greater than the mouth of the vessel. A mixture of oxygen together with entrained powdered materials based on process requirements and a hydrocarbon fluid as cooling agent are blown through tuyeres in the bottom of the vessel and diffuse through the hot metal in the vessel. The inherently finer dust produced from the bottom-blown oxygen process requires that for proper air pollution control a non-combustion system be used to take advantage of the increased agglomerating properties of iron oxides when produced in reducing atmospheres. When blowing is initiated in this process carbon monoxide and hydrogen evolve immediately and in order to render the gases inert, air is aspirated into the gas collector hood so that an inert gas plug is formed which purges the exhaust system of combustion air.
