20140265848 | Micro-Plasma Generation Using Micro-Springs - An ionic wind engine unit for cooling semiconductor circuit assemblies includes a curved micro-spring and an associated electrode that are maintained apart at an appropriate gap distance such that, when subjected to a sufficiently high voltage potential (i.e., as determined by Peek's Law), current crowding at the spring's tip portion creates an electrical field that sufficiently ionizes neutral molecules in a portion of the air-filled region surrounding the tip portion to generate a micro-plasma event. In one engine type the electrode is a metal pad, and in a second engine type the electrode is a second micro-spring. Ionic wind cooling is generated, for example, between an IC die and a base substrate in a flip-chip arrangement, by controlling multiple engines disposed on the facing surfaces to produce an air current in the air gap region separating the IC device and base substrate. | 09-18-2014 |

20150233703 | SPATIAL MODULATION OF LIGHT TO DETERMINE OBJECT LENGTH - Spatially modulated light emanating from an object moving along a flow path is used to determine various object characteristics including object length along the flow direction. Light emanating from at least one object moving along in a flow path along a flow direction of a spatial filter is sensed. The intensity of the sensed light is time modulated according to features of the spatial filter. A time varying electrical signal is generated which includes a plurality of pulses in response to the sensed light. Pulse widths of at least some of the pulses are measured at a fraction of a local extremum of the pulses. The length of the object along the flow direction is determined based on the measured pulse widths. | 08-20-2015 |
20150233704 | SPATIAL MODULATION OF LIGHT TO DETERMINE DIMENSIONAL CHARACTERISTICS OF OBJECTS IN A FLOW PATH - A device includes a spatial filter arranged in a Cartesian coordinate system having orthogonal x, y, and z axes. The spatial filter has mask features that are more light transmissive and mask features that are less light transmissive. The mask features are arranged along the x-axis in the flow direction of a flow path. A detector is positioned to detect light emanating from at least one object in the flow path, the object having a width along the y-axis, a thickness along the z-axis, and a length along the x-axis. Light emanating from the object is time modulated according to the mask features as the object moves along the flow path. The detector is configured to generate a time-varying electrical signal in response to the detected light that includes information about the width or thickness of the object. | 08-20-2015 |
20150276387 | SPATIAL MODULATION OF LIGHT TO DETERMINE OBJECT POSITION - Approaches for determining object position in a flow path are disclosed. A system includes a spatial filter having a length disposed along a longitudinal axis of the flow path and a width along a lateral axis of the flow path. The spatial filter has mask features configured to modulate light. Light emanating from objects moving along the flow path is detected. The detected light has a component along a detection axis that makes a non-zero angle with respect to the longitudinal and lateral axes. An electrical output signal that includes information about the trajectory depth of the object is generated in response to the detected light. | 10-01-2015 |
20150276486 | DETERMINATION OF COLOR CHARACTERISTICS OF OBJECTS USING SPATIALLY MODULATED LIGHT - A system is configured to determine a color distribution of an object moving along a flow direction relative to a spatial filter. The light emanating from the object is time modulated according to the mask features of the spatial filter. First and second detectors are arranged to sense the modulated light. The first detector senses light having a first wavelength spectrum and generates a first electrical output signal in response to the sensed light. The second detector light senses light having a second wavelength spectrum and generates a second electrical output signal in response to the sensed light. Signals from the first and second detectors include information about color distribution of the object. | 10-01-2015 |

An electron blocking layer (EBL) disposed between the p-side heterostructure and the active region comprises an aluminum containing group-III-nitride alloy. An aluminum composition of the EBL decreases as a function of distance along a [0001] direction from the active region towards the p-side heterostructure over a majority of the thickness of the EBL. | 10-01-2015 |

20150273595 | Device for Automatically Drilling Wheel Rim Online - The present invention provides an automatic wheel rim online drilling device, comprising a frame, an air cylinder, a profiling drill jig, a drill bush, a servo electric cylinder, a drilling power head, etc. Firstly, a sensor enables a wheel to be positioned, and the air cylinder causes left clamping blocks to move rightward by two guide rods and guide sleeves so as to clamp the wheel jointly with a right clamping block; the servo electric cylinder causes a drilling system to move toward the wheel and the profiling drill jig can first come into good contact with the wheel rim and then the servo electric cylinder moves continuously to compress upper and lower springs so that the drill bit enters the drill bush, and at this time the drilling power head drives the drill bit to rotate, thus starting drilling on the wheel rim. By using the device of the present invention, X-ray rejects of wheels can be automatically marked by drilling, and the device can adapt to flow casting spun blanks with thick rims; and through orientation of the drill bush, the situation that the drill bit is frequently broken when drilling on the arc surface of the outer side of the wheel rim can be effectively avoided. | 10-01-2015 |

When the bristle units need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of a top plate, so that all the bristle units will fall off against the suction force of strong magnets under the action of each jacking post. According to the present invention, it avoids being time consuming and labor intensive due to removing the bristle units one by one by using a screw driver or other similar devices while replacing the bristle units, and at the same time the replacing speed of bristles is greatly increased. | 10-29-2015 |
