Abstract: A cable-wound drum style hoist with a rotating shaft supported by bearings that has both: (i) some freedom of motion in (at least) one of the bearings; and (ii) a pillow block in the shaft to impart some freedom of motion (beyond freedom to rotate about the central axis) in the shaft itself. By allowing some freedom of motion both the bearing(s) and the shaft, the hoist can better accommodate for bent shafts and/or slight misalignment of coaxial bearings. Also, a set of preferred connection hardware for mechanically connecting a hoist reducer box to a hoist backbone with preferred degrees of freedom/constraint.
Abstract: An embodiment of the invention is a composition of diesel, biodiesel or blended fuel (DF) with exhaust gas (EG) mixtures or with liquid CO2. The composition is in a liquid state near the supercritical region or a supercritical fluid mixture such that it quasi-instantaneously diffuses into the compressed and hot air as a single and homogeneous supercritical phase upon injection in a combustion chamber. Suitable temperatures and pressures are greater than about 300° C. and 100 bar, and the mole fraction of EG or CO2 (XEG or XCO2) in DF is in the range of 0.0-0.9. In a combustion process embodiment, composition embodiments are injected into a combustion chamber under supercritical conditions.

Abstract: An electrically powered two wheel mowing, trimming and edging apparatus is disclosed. A rotating cutting head is cantilevered in front of the wheels, with a battery positioned behind the wheels to act as a counterweight to the cutting head. A caster below the battery allows easy maneuverability and permits trimming in corners. The cutting head contains both metal cutting blades and filament line, and the operator selects which cutting tool he wants based on the type of foliage to be cut. The cutting head easily rotates from the horizontal to the vertical, allowing the apparatus to be used as an edge trimmer.
Abstract: A light guide apparatus includes a light guide layer having a top surface and a bottom surface, and a transversely oriented side-end surface that forms an output aperture of the light guide, characterized by an index of refraction, n1, and further characterized by a length dimension in an intended light propagation direction towards the output aperture, where the intended light propagation direction is a z-axis direction of a Cartesian coordinate system; and a plurality of light injection elements disposed in the form of at least one linear strip in at least one of the top and bottom surfaces of the light guide layer, wherein some of the plurality of light injection elements are disposed on one lateral side of the strip and some other of the plurality of light injection elements are disposed on an opposing lateral side of the strip, further wherein each light injection element is disposed outwardly at a rotation angle ?z about the y-axis.

Abstract: The present invention is directed to a surface mountable circulator/isolator device that includes a first dielectric layer having an electric circuit formed thereon. A second center dielectric layer is disposed adjacent the first dielectric layer, the center dielectric layer including an opening formed therein, the opening being aligned relative to the electric circuit. A ferrite element is disposed in the opening such that the ferrite abuts the electric circuit and is aligned in two-dimensions relative to the electric circuit. A third dielectric layer is disposed adjacent the second center layer. The third dielectric layer includes a ground plane formed on each major surface thereof. The first dielectric layer, the second center dielectric layer, the ferrite element, and the third dielectric layer are bonded together to form a laminated multi-layer structure. A permanent magnet is bonded to the second ground plane.
Abstract: A method for manufacturing or preparing thin-film stacks that exhibit moderate, finite, stress-dependent resistance and which can be incorporated into a transduction mechanism that enables simple, effective signal to be read out from a micro- or nano-mechanical structure. As the structure is driven, the resistance of the intermediate layers is modulated in tandem with the motion, and with suitable dc-bias, the motion is directly converted into detectable voltage. In general, detecting signal from MEMS or NEMS devices is difficult, especially using a method that is able to be integrated with standard electronics. The thin-film manufacturing or preparation technique described herein is therefore a technical advance in the field of MEMS/NEMS that could enable new applications as well as the ability to easily develop CMOS-MEMS integrated fabrication techniques.

Abstract: A system for identifying test tube types and properties in a sample handling machine using visual information automatically obtained by an optical imager and then processed using vision processing methods. The system includes an optical imager positioned to capture images containing one or more test tubes in a rack and a microcontroller programmed to extract predetermined regions of interest and interpret the optical information in the image to decipher the dimension of the test tubes, determine the presence or absence of caps on the test tubes, decode any encoded data, and interpret custom symbologies. The system may then determine the nature of the test tubes or other containers presented before the image and provide that information to the sample handling machine to assist with processing of samples.
Abstract: A system for obtaining an image of an object using an optical imager having an illumination source that is positioned on one side of the object to be imaged and a reflective background positioned on the other side of the object. The imaging system may be implemented in an assembly line or sample processor by using at least one imager and a reflective background positioned behind the samples moving along the assembly or process line. The imager is programmed to decode barcode information and to identify objects in the image using pattern matching techniques.
Abstract: A bacteriorhodopsin based chemical sensing architecture based upon the collective response of bacteriorhodopsin and a number of its mutants; the wild type protein and a selection of genetically-engineered variants was able to respond differentially to a selection of amines. The observable response to the presence of a target chemical was manifested through a modulation of bacteriorhodopsin's photokinetic properties, which are monitored through pump-probe techniques using a custom prototype flash photolysis system. Differential responsivity exists at two levels; (1) bacteriorhodopsin proteins (wild-type and genetically-engineered variants) respond differentially upon exposure of a target chemical, and (2) the response pattern exhibited by the proteins differs from chemical to chemical. This dichotomy forms the basis for a BR-mediated chemical sensing technology that is highly sensitive and selective and may therefore discriminate between different chemicals.

Abstract: A nut assembly for quick adjustment of axial position relative to a threaded shaft. The nut is formed in two, physically separate sections, each having a surface portion with threads for mating engagement with the shaft. Each nut section is pivotally mounted to a bushing which surrounds the threaded shaft for movement of the nut threads into and out of engagement with the shaft threads. The sections are moved about their pivotal mountings by movement of a second bushing axially with respect to the first bushing through cooperative conical surfaces on the second bushing and on each of the nut sections.
Abstract: A system for automatically identifying a logo or trademark applied to a device and verifying that the logo or trademark is acceptably identifies a compatible device. The system uses an optical imager to capture optical images of the target device and a microcontroller interconnected to the imager for processing the optical image to extract image information and verify that the contents of the image reflect the appropriate manufacturer or supplied indicia required by a host device. The decision reached by the microcontroller may be provided externally to a host device, thereby precluding or allowing use of the device, or provided directly to a user via know means, such as a visual display or audible output.
