Abstract: Power tools with conductive couplings used with active injury mitigation technology are disclosed. Conductive couplings are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology. Conductive couplings provide a mechanism through which an electrical signal can be coupled or imparted to a blade, and then monitored for changes indicative of human contact with the blade. An exemplary conductive coupling includes a brush that establishes an electrical connection with a moving part of a power tool, and the brush maintains contact with the moving part of the power tool during at least 40 hours of cumulative time when the motor is spinning the arbor and blade without an interruption in the electrical connection sufficient to trigger the reaction system. A conductive coupling may be two-sided compliant. A conductive coupling may connect to a motor shaft to minimize electrical noise.

Abstract: In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission. A base station is configured to transmit data to a mobile station according to a first configuration of two or more component carriers, to determine that a change of configuration to a second component carrier configuration is required, and to signal the change of configuration to the mobile station, using the first configuration of component carriers. The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration.

Abstract: An external fixator system includes a proximal frame configured to restrict motion in a lower extremity of a subject, and a frame connector assembly. The proximal frame includes a first, second, and third component. The first component can support a first clamp to secure a first pin inserted within a bone extending between a foot and a knee of the lower extremity. The third component extends from a second end of the second component. The first, second and third components have longitudinal axes that are substantially coplanar. The third component includes an extension to extend over a dorsal portion of the foot of the subject and to support a second clamp to secure a second pin inserted within a bone of the foot. The frame connector assembly extends from the second component to support a third clamp to secure a third pin inserted within a third bone of the foot.

Abstract: This invention relates in part to plant breeding and herbicide tolerant plants. This invention includes a novel aad-1 transformation event in corn plants comprising a polynucleotide sequence, as described herein, inserted into a specific site within the genome of a corn cell. In some embodiments, said event/polynucleotide sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. Additionally, the subject invention provides assays for detecting the presence of the subject event in a sample (or corn grain, for example). The assays can be based on the DNA sequence of the recombinant construct, inserted into the corn genome, and on the genomic sequences flanking the insertion site. Kits and conditions useful in conducting the assays are also provided.

Abstract: Systems and methods for facilitating user interaction such as within a social network are described. In one implementation, location-based display of images and/or other information associated with other users or entities may be provided. The information may be provided in association with mapping or other positional data or information such as personal interests.

Abstract: Representative embodiments disclose mechanisms for data and identity migration, such as from an on-premises environment to a cloud environment. The system comprises multiple data collectors, each tailored to collect data from a data source. In a representative example, data collectors for a source application, a source identity repository and a target identity repository are utilized. Once the data is collected, it is stored in a database and methods are used to identify correlations (i.e., matches) between the source application data, the source identity repository data and the target identity repository data. The correlations are memorialized and presented to a user for rationalization. The process is stateful so that prior decisions are remembered. Once the user is satisfied with the rationalization, the system exports files that are consumed by a migration process to perform the actual data migration.

Abstract: An illustrative fuel delivery system for an engine can include a fuel type indicator device and a flow management device. The flow management device can be configured to receive fuel from an auxiliary fuel tank and to direct it based on the type of fuel in the auxiliary fuel tank. If the type of fuel in the auxiliary fuel tank is a primary fuel type (such as diesel or gasoline), the flow management device can deliver the primary fuel to a piston cylinder of the engine. If the type of fuel in the auxiliary fuel tank is an auxiliary fuel (such as a mixture of ethanol and water the flow management device can deliver the auxiliary fuel to an air intake system of the engine.

Abstract: A method of determining a smooth reference line for navigating an autonomous vehicle in a manner similar to human driving is disclosed. A high density map is used to generate a centerline for a lane of roadway. Using the centerline, a number of sample points is generated that is related to a curvature of the centerline. Adjustment points are generated at each sample point, a few on either side of the centerline at each sample point. Candidate points at a sample point include the adjustment points and sample point. A least cost path is determined through each of the candidate points at each of the sample points. Path cost is based an angle of approach and departure through a candidate point, and a distance of the candidate point from the centerline.

An access control computer system is communicatively coupled to the unified access control device and includes databases storing guest enrollment data and entitlement data associated with the guest enrollment data. The unified access control device identifies entitlements associated with the guest identification data based on a comparison between the guest identification data, the guest enrollment data, and the entitlement data, and controls guest access through the entrance based on the identified entitlements.
