Abstract: An implantable device for occluding a septal defect has interleaved frame sections that allow flexibility to conform to a variety of defect geometries and provide reliable occlusion during endothelialization. Left and right frames connect to opposite ends of a floating connection post. The device is resiliently deformable and is biased into a natural state wherein, in situ in a variety of defect geometries, the device applies a sandwiching force to the tissue surrounding the defect that is relatively uniform across its diameter, improving stability and promoting occlusion.

Abstract: A method is disclosed for producing a high quality bulk single crystal of silicon carbide in a seeded growth system by reducing the separation between a silicon carbide seed crystal and a seed holder until the conductive heat transfer between the seed crystal and the seed holder dominates the radiative heat transfer between the seed crystal and the seed holder over substantially the entire seed crystal surface that is adjacent the seed holder.

Abstract: A method for controlled growth of silicon carbide and structures produced by the method are disclosed. A crystal of silicon carbide (SiC) can be grown by placing a sacrificial substrate in a growth zone with a source material. The source material may include a low-solubility impurity. SiC is then grown on the sacrificial substrate to condition the source material. The sacrificial substrate is then replaced with the final substrate, and SiC is grown on the final substrate. A single crystal of silicon carbide is produced, wherein the crystal of silicon carbide has substantially few micropipe defects. Such a crystal may also include a substantially uniform concentration of the low-solubility impurity, and may be used to make wafers and/or SiC die.

Abstract: A new and useful a semi bolt receiver assembly is provided, that configured for assembly with a rifle base that has a buttstock and pistol grip configured for semi automatic operation. The semi bolt receiver assembly includes a receiver, a bolt and carrier assembly, and a manually operable handle that is coupled with the bolt and carrier assembly in a manner that enables the bolt and carrier assembly to be manipulated by a shooter to charge the rifle (i) while the shooter is maintaining a shooting position and (ii) without removing the shooter's hand from the pistol grip. The semi bolt receiver assembly is particularly useful when configured for assembly with an AR-15 rifle base.

Abstract: A system for presenting on-line advertising for goods and services to a user. After determining a geographic location of interest the method runs a query for retrieving candidate advertisements based on geographic location of interest, an advertiser type, and values in an influence map. The influence map is constructed by overlaying geographic location data onto an XY grid of cells and dividing cells into sub-cells that approximate various political or natural boundaries or other devised degrees of separation. Influences from geographically defined locations are propagated iteratively to neighboring cells, thus providing a continuous metric for influence across discontinuous geographic boundaries. Having now a measure of influence of a particular geographic feature and a user's suggestion of desired goods and/or services, advertisements are presented to the user in form of an ordered list, or in a web page frame, or on a geographic- or influence-oriented map.

Abstract: The invention is a method of inspecting a semiconductor wafer surface for scratches. The method includes positioning a semiconductor wafer for illumination by a radiation source and adjacent a background material that will absorb radiation from the radiation source, directing radiation at a surface of the wafer from the radiation source that has a wavelength that will be absorbed by the fundamental absorption of the wafer, filtering or otherwise limiting the radiation to allow only radiation having wavelengths that are absorbed by the fundamental absorption of the wafer to pass, and detecting radiation scattered on the surface of the wafer and filtered, by position, to thereby identify the location of the scratches on the surface of the wafer, while the absorption of the background material prevents other radiation from the source from interfering with the detection of the scratch-scattered radiation.

Abstract: A novel security system for use by a homeowner in protecting their premises, that is responsive to the presence of an intruder or others, the security system includes a housing for a motion detector, a recorder/playback system, a photo sensor, and a light display. In one embodiment, when the motion detector senses the presence of a person or an intruder it activates the photo sensor and the recorder/playback system, where the recorder/playback system will automatically play an outgoing message. If the event occurs during nighttime hours then the light display is simultaneously energized. The light display of the present invention includes a visual message, which may be symbolic or readable. The recorder/playback system may also allow an incoming message to be recorded by a person who is detected by the security system, the incoming message being kept for later playback by the homeowner.

Abstract: The shingle removing machine includes a frame supporting a power source, which, in turn, drives a lateral axle with a wheel at each end thereof, with each wheel having an eccentric pin driving a blade drive arm. Separate wheels support the frame. Each blade drive arm extends forwardly and has a relatively wide shingle removal blade at its forward end. The blades extend substantially the width of the machine. The forward ends of the blade drive arms are interconnected and include rollers riding on sloped ramps on the forward end of the frame. Rotation of the blade arm drive wheels reciprocates the blade drive arms forwardly and rearwardly, with the blades also lifting and lowering during the cycle as the forward ends of the arms ride up and down the ramps. The blade drive arm assembly may be quickly and easily disassembled for maintenance and repair in the field.
