Patent CA-2269555-A1 (CA)
Title: Apparatus and method for forming oxygen-enriched gas and compression thereof for high-pressure mobile storage utilization
Inventor: GOERTZEN GEROLD G
IPC: B01D53/04
Filed: 1998-09-16
Abstract: An oxygen concentrator is utilized in combination with a compressor to provide a highly enriched and compressed oxygen gas in a mobile container such as a gas cylinder, The combination and method of production provides for the facile preparation of an enriched source of oxygen for use by an ambulatory or wheelchair-confined patient. The oxygen concentrator utilizes two or more molecular sieves to provide a breathable gas of from approximately 80 to about 98 percent oxygen from atmospheric air. The oxygen-enriched gas is stored in a concentrator product tank and can be prioritized so as to supply a patient with a proper amount and concentration of oxygen and secondarily to supply any surplus or excess enriched oxygen to a compressor.  The compressor utilizes multiple stages to produce the highly compressed oxygen-enriched gas and utilizes a two-part piston at low rpm to enhance low wear and low noise. The multiple pistons of the compressor can either all rotate at one RPM or in an alternative embodiment, at least a first piston can rotate at a higher RPM than any remaining pistons. Desirably, at least the initial piston of the alternative embodiment is driven by one drive shaft source with one or more other remaining pistons being driven by a second drive shaft.

Title: Data communication method in mobile communication system
Inventor: LEE SUNG WON
IPC: H04W28/00
Filed: 1999-01-25
Abstract: A method for increasing a channel efficiency and saving a transmission power by controlling outputs of a dedicated control channel and a pilot channel when data transmission is discontinued temporarily during the data communication in a mobile communication system. The mobile communication system includes an active state (117) in which user data is transmitted through a dedicated traffic channel and a control message is transmitted through a dedicated control channel when there exists information to transmit. A base station of the mobile communication system comprises the steps of transitioning to a first control hold state for releasing the dedicated traffic channel and maintaining the dedicated control channel, when there is no data to transmit for a first set time in the active state; and transitioning to a second control hold state for logically connecting the dedicated control channel to control an output of a transmission signal, when there is no data to transmit for a second set time in the first control hold state. Here, the data to transmit is user data and control data. Further, the logical connection in the second control hold state discontinues, in a state where the channel resource is logically assigned, a transmission output of a corresponding channel.

Abstract: Fluorescent indicators including a binding protein moiety, a donor fluorescent protein moiety, and an acceptor fluorescent protein moiety are described. The binding protein moiety has an analyte-binding region which binds an analyte and causes the indicator to change conformation upon exposure to the analyte.  The donor moiety and the acceptor moiety change position relative to each other when the analyte binds to the analyte-binding region. The donor moiety and the acceptor moiety exhibit fluorescence resonance energy transfer when the donor moiety is excited and the distance between the donor moiety and the acceptor moiety is small. The indicators can be used to measure analyte concentrations is samples, such as calcium ion concentrations in cells.
