摘要:
The present invention is a nitrous oxide safety system or method that provides a safety control valve actuated by low-vacuum fluids to control the release of nitrous oxide therethrough. The nitrous oxide safety system may include a low-vacuum fluid, a nitrous oxide fluid, a scavenging mask assembly, and a safety control valve. The low-vacuum fluid is generated by a vacuum source operating to achieve a predetermined parameter and the nitrous oxide fluid is provided by a nitrous oxide source. The scavenging mask assembly is fluidly connected with the nitrous oxide source and the vacuum source. The safety control valve is fluidly connected to the fluid connection between the nitrous oxide source and the vacuum source. The safety control valve is configured to be actuated when the low-vacuum fluid is input to the valve to release a flow of the nitrous oxide fluid through the safety control valve.

The present invention is a method and system for administering nitrous oxide. The system includes a fluid control system for controlling the flow of nitrous oxide and oxygen to the patient. A nitrous oxide and oxygen supply, vacuum source, a breather bag, and a nasal delivery interface system are fluidly connected to the fluid control system and a patient. The fluid control system also includes a safety scavenge system including a mass airflow sensor, master controller, nitrous oxide valve, and alarm. The mass airflow sensor reads the scavenging vacuum pressure which it communicates to the master controller. Depending upon the scavenging vacuum pressure, the master controller can activate an alarm or shut off the flow of nitrous oxide. In operation, the present invention provides a system for administering anesthesia/analgesia gas which prevents excessively high volumes of exhaled nitrous oxide in the operatory environment through monitoring of the scavenge vacuum pressure.

Electronic messaging systems, a machine-accessible medium, and methods for text-based electronic communication. In one embodiment, a plurality of databases are provided. The databases each define shorthand terms with one or more longhand terms. A shorthand term is targeted within a text message, and the databases are searched for corresponding longhand terms. The longhand terms are selected for display according to factors such as user preferences, the identities of participants to the text communication, and the context of the text message. Abbreviations, shorthand, and other jargon sent by one user is thereby interpreted. For example, one of the longhand terms may be substituted in-line with the text message. Alternatively, all matches for the shorthand term found in the databases may be listed in descending order according to relevancy.

In an object oriented computer system, an object oriented mechanism and method defines a common interface to maintain elements on a collection while providing the capability of using virtually any suitable object as a key to the collection. A programmer defines an interface on a collection that includes suitable object methods for adding, removing, and replacing elements of the collection. The constraints that determine whether elements may be added, removed, or replaced is encapsulated in a policy that is defined by the programmer. The programmer identifies one or more keys, which may include any suitable object in the object oriented system. A maintainer class provides a client interface for maintaining elements on the collection according to the defined policy and according to the keys defined by the programmer. The present invention recognizes the common characteristics that exist in maintaining elements on a keyed collection, and provide predetermined classes and class relationships that provide support for maintaining any collection using any key that a programmer may define.

In one aspect, the present invention provides a silicon photodetector having a surface layer that is doped with sulfur inclusions with an average concentration in a range of about 0.5 atom percent to about 1.5 atom percent. The surface layer forms a diode junction with an underlying portion of the substrate. A plurality of electrical contacts allow application of a reverse bias voltage to the junction in order to facilitate generation of an electrical signal, e.g., a photocurrent, in response to irradiation of the surface layer. The photodetector exhibits a responsivity greater than about 1 A/W for incident wavelengths in a range of about 250 nm to about 1050 nm, and a responsivity greater than about 0.1 A/W for longer wavelengths, e.g., up to about 3.5 microns.
