Abstract: A motor drive or bus supply power conversion system includes a rectifier with at least one rectifier switch module for rectifying AC input power. A DC bus is connected to the rectifier and supplies DC output power. An optional inverter is connected to the DC bus and includes at least one inverter switch module for inverting the DC bus voltage to an AC output power. The at least one rectifier switch module and the at least one inverter switch module each include a base plate and a housing connected to the base plate. The housing defines an interior space that contains at least one semiconductor switch. Anti-corrosion features are provided including a conformal coating on printed circuit board assemblies, removable connector covers, dielectric grease coated connections, nano-coated fiber optic transceivers, and an exterior protective film wrap.

Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed-origin bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal seeds and/or seedlings) with heterologous seed-derived bacterial endophytes.

Abstract: An adjustable holder assembly and a track for supporting a plurality of holder assemblies thereon where each holder assembly adjusts to hold objects of various sizes, weights, dimensions, shapes and uses. The track slidably supports a plurality of holder assemblies spaced apart thereon. For example, the holder assemblies may each hold a different object and the spacing between each holder assembly adjusted to accommodate the objects held therein and/or hanging therefrom without interference from adjacent objects.

Abstract: An apparatus includes a housing fixed adjacent to a door having a hinge, a rotating arm rotatable about the housing and biased toward the door, and a transmitter electronically coupled to the rotating arm, wherein the transmitter broadcasts a position of the door.

Abstract: A method of identifying the presence of heroin in an impure heroin composition which contains heroin and at least one fluorescent contaminant which interferes with a Raman signal from the heroin. The method may include contacting the mixture with a solvent such as an alcohol, then contacting the resulting alcohol composition with a SERS surface. The surface may then be exposed to laser light from a hand-held Raman spectrometer to detect a Raman signal from the heroin. An apparatus for performing the method is also provided.

Abstract: A stroller roller, configured to be attached to a stroller having a frame attached to a wheel. The stroller roller includes a wheel clamp assembly configured to grasp the wheel. An extendable arm assembly is attached to the wheel clamp assembly. A frame clamp assembly is attached to the extendable arm assembly and configured to grasp the frame. The frame clamp assembly pushes the extendable arm assembly causing the wheel clamp assembly to rotate the wheel both clockwise and counterclockwise.

Abstract: A method for performing anonymous authentication by an electronic device is described. The method includes obtaining biometric data. The method also includes enrolling biometric information based on the biometric data. The method also includes generating backup biometric information based on the biometric data. The backup biometric information includes a backup biometric template. The method also includes generating a backup public key and a backup private key. The method also includes enrolling the backup biometric information. Enrolling the backup biometric information includes distributing the backup biometric template, the backup public key and the backup private key among different entities.

Abstract: A method for anonymous authentication by an electronic device is described. The method includes obtaining biometric data. The method also includes generating a token. The method also includes blinding the token to produce a blinded token. The method also includes sending the blinded token and biometric information based on the biometric data to a verifier. The method also includes receiving a signature of the blinded token from the verifier if corresponding biometric information is not stored by the verifier.

Abstract: Techniques for personalizing content are presented. A principal requests access to content. Policy is evaluated in response to the request for the content. Scripts are processed in response to the policy evaluation to rewrite and modify the content. The modified content is then delivered to the requesting principal to personalize the content for the principal.

Abstract: Techniques for dynamic generation and management of password dictionaries are presented. Passwords are parsed for recognizable terms. The terms are housed in dictionaries or databases. Statistics associated with the terms are maintained and managed. The statistics are used to provide strength values to the passwords and determine when passwords are acceptable and unacceptable.

Abstract: Techniques for representing extensible markup language (XML) in an executable format are presented. An XML document is parsed into its components and content. The components and content are packaged as an executable. Some portions of the executable include authentication logic or policy logic that is subsequently enforced when the executable is processed. The executable is subsequently distributed to recipient machines. The machines process the executable and produce memory loaded versions of the components and content representing the XML document on the machines. The memory loaded versions of the components and content include conditionally added authentication logic of policy logic.

Abstract: Techniques for modification of access expiration conditions are presented. A principal supplies a password associated with establishing access to a target resource. In response to the password, characteristics of the password are examined and a custom expiration condition is generated for the password in response to the characteristics and policy. When the custom expiration condition is satisfied, the password and access to the target resource become invalid for use. Moreover, the principal may interactively change a complexity level of any proposed password for purposes of attempting to enhance the expiration condition or for purposes of attempting to degrade the expiration condition.

The method also includes generating a biometric template based on the biometric data. The method also includes encrypting the biometric template. The method also includes sending the encrypted biometric template to a storage device.
