The present invention relates to a removable tile spacer for enabling even spacing between a first tile and a second tile that are perpendicular to each other. The second tile has an end opposite the first tile. The removable tile spacer includes a first elongate member interposable between the first tile and the end of the second tile to provide spacing between the first tile and the second tile. The tile spacer includes a body. The first elongate member is connected to and extends away from the body at an angle relative to the body such that the body has at least a portion which is spaced-apart from both the first tile and the second tile when the first elongate member is interposed between the first tile and the end of the second tile. This thereby facilitates removal of the tile spacer when tile spacing is completed.

A mechanical independent blade control (MIBC) mechanism for controlling the pitch of each of the blades of a rotor blade system or a main rotor of a rotor aircraft independently of the other blades includes a plurality of actuators disposed in the fuselage below the hub of the rotor, each being operable to selectively control the pitch of an associated one of the blades independently of the other blades, and a plurality of mechanical linkages disposed within the annulus of the rotor mast, each coupled between a blade and an actuator and operable to transmit a force output by the actuator to a pitch horn fixed to an inner end of the associated blade. The mechanism enables the direction of pitch of each blade to be changed more than twice during one revolution of the rotor.

A wine glass constructed from molded plastic includes an upper body defining an upwardly narrowed flume for concentrating the wine bouquet, in combination with a contoured lower base defining an annular moat surrounding a central punt for enhanced visual inspection of the wine. In addition, the upper body further includes a notched indent at an outboard side thereof forming a shelf for facilitated fingertip grasping and manipulation of the assembled glass. In one form, the upper body and lower base of the wine glass are provided as separate modules adapted for assembly to form the wine glass, and disassembly for respective compact stacking. In another form, the wine glass has a one-piece construction adapted for compact stacking by nested reception of the upwardly narrowed flume partially into the underside of the lower base of an overlying glass in the stack.

The invention relates to a rail transit fault diagnosis method and system based on a decision-making tree. The method includes the steps of firstly, determining various fault modes and various monitoring quantities of a rail transit device by analyzing a circuit and a mechanical structure model of the rail transit device; secondly, obtaining standard fault sample data according to various historical monitoring quantities of the rail transit device, then, analyzing the standard fault sample data through the decision-making tree generating algorithm, and conducting construction to obtain the decision-making tree of a fault; thirdly, collecting the various real-time monitoring quantities of the rail transit device, taking the decision-making tree as a classification model of the fault modes to conduct classification, and thereby determining the type of the fault. The system comprises a data collection device, a database unit, a data analysis unit and a knowledge base unit. The method and the device solve the technical problems that in the prior art, when the rail signal system fault is manually diagnosed, workloads are large, efficiency is low and the risks are high, and efficiency and accuracy of rail transit data analysis and fault diagnosis are improved.

The invention discloses a method which allocates addresses for the slave node devices in the Modbus communication network; the method includes the steps that the master node device and the slave node devices are initialized; the address of a slave node device is set and the number of the slave node devices is set; the master node device sends the address polling message to each slave node device periodically; when a slave node device receives the address polling message with the data which is the same as the address of the slave node device, the slave node device returns a message which carries the address of the slave node device to the master node device; when the master node device judges that the address of the slave node device is different from the stored address of the master node device, the master node device stores the address of the slave node device; when the number of the addresses of the slave node devices stored in the master node device is equal to the number of the slave node devices, the flow ends. The method which allocates addresses for the slave node devices in the Modbus communication network can conveniently examine that if the address allocation of the slave node devices is completed correctly.

Improved user interface methods facilitate navigation and programming operations for a magnified machine vision inspection system. Large composite images are determined and stored. The composite images include workpiece features that are distributed beyond the limits of a single magnified field of view of the machine vision system. Despite their size, the composite images may be recalled and displayed in a user-friendly manner that approximates a smooth, real-time, zoom effect. The user interface may include controls that allow a user to easily define a set of workpiece features to be inspected using a composite image, and to easily position the machine vision system to view those workpiece features for the purpose of programming inspection operations for them.

Systems and methods for inspecting a surface of a specimen such as a semiconductor wafer are provided. A system may include an illumination system configured to direct a first beam of light to a surface of the specimen at an oblique angle of incidence and to direct a second beam of light to a surface of the specimen at a substantially normal angle.

A dual function condensate drain trap for positive or negative pressure air handling unit applicable in positive or negative pressure environments by switching connecting directions includes a drain trap which has a water inlet and a water outlet on two sides to connect to a drain pipe, and a valve seat and a retaining element located on the valve seat movable between a first position to be in contact with the valve seat and a second position to be away from the valve seat. When the pressure of water column in the water inlet is smaller than that of the water outlet, the retaining element is on the first position to form an air lock to prevent air from entering or escaping from air handling unit. By contrast, when the pressure of water column in the water inlet is greater than that of the water outlet, the retaining element is moved to the first position to drain water.
