Reduced material spigot design for integrated VDA adapter housing with as-cast anti-rotation feature
A throttle control assembly which includes a housing, and an adapter and an anti-rotation feature integrally formed with the housing. A scallop is integrally formed as part of the housing and substantially surrounds the anti-rotation feature. A first tapered portion and a second tapered portion are both integrally formed with the adapter. A first groove and a rib portion are also integrally formed as part of the adapter. A plurality of outer scallops are also integrally formed as part of the adapter. The anti-rotation feature, the scallop, and each of the plurality of outer scallops are integrally formed with the housing. A portion of the plurality of outer scallops are formed as part of the second tapered portion, and a portion of the plurality of outer scallops are formed as part of the rib portion.
The present disclosure generally relates to tin oxide films prepared by physical vapor deposition using a doped tin target. The semiconductor film may include tin and oxygen, and may be formed in a PVD chamber including a silicon doped tin target. Additionally, the semiconductor film may be smooth compared to similarly formed films without a doped target. The semiconductor film may be deposited by applying an electrical bias to a sputtering silicon doped tin target including the silicon in an amount of 0.5 to 5% by atomic weight of the total target. The semiconductor film has a smooth surface morphology compared to similarly formed tin oxide films formed without a doped target.
An vapor purge system for a turbocharged internal combustion engine having an evaporative emissions turbo purge valve incorporating a venturi vacuum generator and a hose-off detection function. The turbo purge valve includes a pressure sensor, and a low restriction check valve which is integrated into the outlet port of the venturi vacuum generator. The pressure sensor is capable of detecting the small pressure drop (i.e., vacuum) generated at the air inlet tube or air box during naturally aspirated conditions. The check valve closes the venturi vacuum generator on the purge side during naturally aspirated conditions, allowing fluid communication to the air intake system through one port only, and the detection of the vacuum during these conditions. If a hose becomes detached, either at the outlet port of the venturi vacuum generator or at the air box, the small vacuum is not detected, and the ECU then diagnoses the hose-off condition.
F02M 25/08 - Engine-pertinent apparatus for adding non-fuel substances or small quantities of secondary fuel to combustion-air, main fuel or fuel-air mixture adding fuel vapours drawn from engine fuel reservoir
A three-port turbo purge module, including a housing having a cavity, and two check valves. During a first mode of operation, the first check valve is open and the second check valve is closed by vacuum pressure generated in an intake manifold, such that purge vapor flows from an inlet port into the cavity, through the first check valve, and into a first port. During a second mode of operation, where the intake manifold is operating under positive pressure, the first check valve is closed such that pressurized air flowing into the first port is accelerated through a venturi device disposed in the cavity, and the second check valve is open such that purge vapor flows from the inlet port into the cavity, through the venturi device and mixes with the high-velocity air, through the second check valve into the second port.

Techniques for automatically linking pages in a web site are provided. In one technique, training data for a machine-learned scoring model is generated that comprises a plurality of features related to content items. The training data comprises multiple entries, each corresponding to a different content item in a first set of content items. For each entry, a corresponding label is based on a ranking of the corresponding content item in one or more search engine results. The machine-learned scoring model is trained based on the training data. For each content item in a second set of content items, multiple attribute values associated with that content item are input into the machine-learned scoring model, which generates a result. Based on multiple results, determining, for a particular web page, a strict subset of the second set of content items to which the particular web page will include one or more links.
A heat shield for a reductant delivery unit (RDU), the RDU including a fluid injector with a fluid inlet and a fluid outlet, and a clamp flange for attachment to a mounting boss of a vehicle exhaust pipe. The heat shield includes a first portion which is attached to the fluid injector so as to at least partly cover the fluid outlet thereof. The first portion serves as a thermal barrier for the fluid injector and a mechanical barrier for preventing particles in the vehicle exhaust pipe from contacting the fluid injector when the RDU is attached to the vehicle exhaust pipe. The heat shield further includes a second portion which extends radially outwardly from the first portion for sealing the attachment between the clamp flange and the mounting boss of the vehicle exhaust pipe when the RDU is attached thereto.

The present application discloses an iris identification system and an iris identification method thereof. The iris identification system includes: a camera module including at least two cameras, the cameras having different depths of field and being configured to capture iris images; a distance detection apparatus configured to detect a distance between a user and the camera module; a processing chip configured to find, according to the detected distance, a depth of field corresponding the distance and control a camera having the depth of field to be turned on, and further configured to control multiple cameras in the camera module to be turned on simultaneously until one camera has captured an ideal image. At least two cameras having different depths of field are disposed in the iris identification system provided in the present application; a camera having a suitable depth of field is turned on correspondingly according to a detected distance between a user and a camera module to capture an image, or multiple cameras are turned on simultaneously until one camera has captured a clear iris image. The present application achieves good man-machine friendliness and a short capturing time and improves the efficiency of iris identification.
