An exhaust emission control method for treating exhaust gas emitted from an internal combustion engine is provided in which an emission control device located in an exhaust gas passage of the engine stores SOx when the air/fuel ratio of exhaust gas is lean, and releases the stored SOx when the temperature of the emission control device is raised to a desulfurization temperature or higher and the air/fuel ratio of the exhaust gas becomes substantially equal to the stoichiometric air/fuel ratio or rich. In the method, a temperature control process is performed to control the temperature of the emission control device to be within a predetermined temperature range whose lower limit is substantially equal to or higher than the desulfurization temperature, and a desulfurization process is performed to release sulfur from the emission control device by controlling the air/fuel ratio of the exhaust gas to be substantially equal to the stoichiometric air/fuel ratio or rich when the temperature of the emission control device is within the predetermined temperature range. In the method, the temperature control process and the desulfurization process are repeated when sulfur is to be released from the emission control device.

A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

A control apparatus stops supply of a fuel to an engine (a) when a value of a parameter relating to a misfire of the engine satisfies a misfire condition that is set based on an octane value of the fuel, or (b) when it is determined that a misfire may occur if an increased amount of the fuel is supplied to the engine in the case where ignition timing of the engine is retarded based on an octane value of the fuel, and the amount of the fuel is increased according to a retard amount of the ignition timing.

The invention belongs to the technical field of industrial welding seam defect detection, and particularly relates to a crack defect detection method for an industrial welding seam X-ray image, and the method comprises the following steps: carrying out self-adaptive histogram equalization processing with low limit contrast on a to-be-detected industrial welding seam original X-ray image; performing de-noising processing on the equalized image by adopting non-local mean filtering to obtain a de-noised X-ray image; performing class edge texture detection on the de-noised X-ray image by adopting a Canny algorithm to obtain a preliminary detection result; and screening the preliminary results to obtain crack defect detection results. According to the method, the result obtained through the Canny algorithm is further filtered and screened, the edge of the welding seam can be removed to a great extent through the algorithm, only the crack type defects in the welding seam are reserved, and the detection rate of the crack type defects in the final result is extremely high.

The circuit breaker is intended for installation in a low-voltage distribution board having a socket and having at least two busbars which are guided parallel, are held on the socket and are each associated with one pole conductor of a multiphase power supply system. This circuit breaker has an enclosure as well as a plug contact for making contact with one of the busbars. The plug contact can be positioned as a function of the position of the busbar with which contact is to be made, and is held on a contact mount, which can be moved transversely with respect to the busbars and can be locked to the circuit breaker enclosure. In a circuit breaker such as this, a pole conductor change from one busbar to another busbar can be carried out quickly and without the use of any tools.

An image edge enhancement apparatus and a method thereof used for adjusting the brightness of a pixel are provided. The image edge enhancement apparatus comprises a first edge judgment circuit, a second edge judgment circuit and a process circuit. The first edge judgment circuit retrieves the edge data of the pixel in a first direction to output a first edge value. The second edge judgment circuit retrieves the edge data of the pixel in a second direction to output a second edge value. The process circuit determines an operation mode according to the brightness of a plurality of adjacent pixels around the pixel, the first edge value and the second edge value to output an adjusted brightness of the pixel according to operation mode. The adjusting method effectively avoids the noise in an image being amplified, and avoids the same edge being repetitively enhanced by different edge judgment circuits.

The invention relates to the field of copper bar machining, in particular to an automatic feeding and cutting device for copper bars. The automatic feeding and cutting device comprises a control cabinet, a feeding bin, a filtering assembly arranged in the feeding bin, a buffering assembly located at the bottom of the feeding bin and a cutting station table. A discharging table is arranged at one end of the cutting station table. A discharging assembly is arranged on the discharging table. A cutting assembly is arranged between the discharging table and the cutting station table. A material push assembly is arranged on the top of the cutting station table. A falling sliding way is arranged on the top of the cutting station table in a lapped manner. The buffering assembly is obliquely located above the falling sliding way. The discharging assembly comprises a diversion block right opposite to the falling sliding way, and a proximity sensor. A control cabinet is electrically connected with the proximity sensor. The end, close to the diversion block, of the falling sliding way is provided with a limiting assembly. By means of the automatic feeding and cutting device for the copper bars, the copper bars can be automatically completely conveyed into a first arc groove, the copper bars are stably moved to a to-be-cut area by means of the structure characteristics in the groove, in addition, the copper bars are effectively pressed and limited, and stability during cutting is ensured.

A cellular mobile radio network includes base stations, a packet control unit capable of communicating with a radio terminal via two or more base stations, and routing means for routing data between a remote unit and the packet control unit. The data transmitted by the remote unit to the terminal are stored temporarily in the packet control unit. The remote unit is adapted to receive from the terminal acknowledgments relating to transmitted data segments and to retransmit data segments that have not been acknowledged on the expiry of a retransmission time depending on the received acknowledgments. Data segments are transmitted from the remote unit to the terminal via a first base station connected to the packet control unit. In response to a request for communication transfer to a second base station connected to the packet control unit, only a portion of the data stored temporarily in the packet control unit is retransmitted to the terminal via the second base station.

The invention discloses a thoracic cavity closed drainage device of respiratory nursing department, which comprises a containing device, which is used for containing hydrops in the thoracic cavity; avacuum pump, which is used for forming a certain vacuum degree in the containing device by vacuumizing; a conduit, one end extending into the containing device and the other end extending into the pleural cavity to direct the hydrops into the containing device; a pressure coordinating mechanism, which is used for compensating the pressure to the containing device to reduce the reduction degree ofthe negative pressure when the patient inhales. When the patient inhales, the volume of the thoracic cavity is increased, so that the negative pressure degree in the thoracic cavity is increased, andmeanwhile, the pressure coordinating mechanism supplements the pressure in the containing device and further supplements the pressure in the thoracic cavity, so that the negative pressure degree in the thoracic cavity is not changed greatly, or to a lesser extent, thereby preventing excessive dilatation of the lungs during inhalation at the beginning of the drainage procedure.
