摘要:
A highly efficient radiant burner assembly (100) for use in a patio heater or the like in areas where people prefer or require low NOX emissions. The efficiencies are created through the use of a spherical burner element (116) that is either formed of a high temperature steel wire mesh or stamping containing apertures of a predetermined size to allow combustion to remain within the burner element and to not cause the temperature of the burner element to exceed the temperature at which NOX are developed. Coating the burner with a catalyst also aids the low emission combustion process. Additional efficiencies are provided by atomizing the fuel before it is mixed with air and by the use of a laminar flow heat exchanger (940) that utilizes a fluid media flowing in a helical coil condenser unit.

A method and system are provided for remotely monitoring the open and close status of a garage door via the internet based on the internet of things concept and NFC (Near Field Communication) technology. The system includes a Door Monitoring & Controlling Device (DMCD) and a web based Advanced Door Management System. The DMCD contains a NFC module, and one or more NFC close/open status tags which work together to monitor the status of the garage door. The NFC tag in this system not only provides status signal but also provides network configure data that eliminates the need to make standalone device configurable for network connectability. The use of NFC technology here will reduce manufacturing cost significantly, and make the configuration easy. The method and system also enable users to remotely open and close the garage door via the internet.

A jig saw comprises a head (1), a motor, a first drive gear linked with a motor output end (3), and a first reciprocating lever (71) fixed with a first saw blade (101). The first drive gear is hinged with an end of a first connecting rod (61) in an upward eccentric manner, and the other end of the first connecting rod (61) is hinged with the first reciprocating lever (71). The jig saw further comprises a second drive gear linked with the motor output end (3). The second drive gear is hinged with an end of a second connecting rod (62) in an eccentric manner, and the other end of the second connecting rod (62) is hinged with a second reciprocating lever (72) that is fixed with a second saw blade (102). A linear limit mechanism that enables the first reciprocating lever (71) and the second reciprocating lever (72) to maintain a distance therebetween and be capable of linear motion is further disposed. The first saw blade (101) and the second saw blade (102) are respectively clamped on inner side surfaces close to each other at lower portions of the first reciprocating lever (71) and the second reciprocating lever (72). Directions of linear reciprocating motions of the first saw blade and the second saw blade are opposite. In the present invention, components are designed to be symmetrical, so that the jig saw runs stably, is easy to operate, and has high working efficiency.

Systems, methods, and apparatus for configuring utility meters are provided. A meter configuration application may be executed by a device that includes one or more computers and that facilitates utility meter configuration. A plug-in module associated with a utility meter type may be received by the device. Based at least in part upon providing the plug-in module to the meter configuration application, a configuration file may be built for the utility meter type. The utility meter may then be configured utilizing the configuration file.

A microfabricated electrochemical gas sensor is disclosed. The sensor includes electrodes produced from conductor layers, a capping layer, microcavities through the conductor layers and the capping layer, a cavity connecting the microcavities, and an electrolyte filling in the space created by the cavity and the microcavities in the substrate. The microcavities allow gases to pass through but retain the electrolyte through surface tension.
摘要:
This invention describes an electrochemical gas sensor that utilizes microfabrication to achieve miniaturization without using a membrane. The sensor is comprised of thin film electrodes and insulators, and micro cavities in them. The micro cavities are filled with a liquid electrolyte that is kept in the micro cavities by surface tension.

摘要:
An electrochemical piezoelectric sensor is disclosed. The sensor includes a piezoelectric substrate, three (or more) electrodes over a first surface of the substrate, and another electrode over a second (opposing) surface of the substrate. An ionic liquid in the form of a film is adhered, bound, immobilized, or otherwise positioned over the substrate and electrodes of the first surface. The ionic liquid film permits the absorption and detection of analytes from a gaseous sample, for environmental gases, example explosive vapors and/or explosive vapor species in the gaseous sample. Detection (optionally including analyte quantitation and qualitative identification) can be performed by both electrochemical and piezoelectric techniques using a single sensor. Systems incorporating and methods of using the electrochemical piezoelectric sensor also are disclosed.
