  • Patent number: 8721761
    Abstract: A surface covering composition of abrasion resistant character adapted for disposition in overlying bonded relation to a metal substrate. The surface covering composition includes metal carbide particles within a metal matrix at a packing factor of not less than about 0.6. Not less than about 40 percent by weight of the metal carbide particles are characterized by an effective diameter in the range of +14-32 mesh prior to introduction to the metal matrix. Not less than about 3 percent by weight of the metal carbide particles are characterized by an effective diameter of +60 mesh prior to introduction to the metal matrix.

  • Publication number: 20120173258
    Abstract: Methods and apparatus for providing clinical decision support to a healthcare provider. Eligibility criteria and quality measure information for a plurality of performance-based programs is stored and shared quality measures across performance-based programs are identified. Provider and patient characteristics are compared to the stored eligibility criteria and quality measure information to determine which quality measures apply to which providers and patients of the providers. A healthcare provider is provided with a notification at the point of care indicating a recommended action that, when performed by the healthcare provider will satisfy a quality measure in compliance with one or more performance-based programs. Customized reports may be generated and transmitted to program sponsors of performance-based programs, based on formatting rules specified by the program sponsors.

  • Publication number: 20120159268
    Abstract: A hosting provider operates a server system that provides a service to one or more tenants. The server system receives configuration data from the tenants. As part of providing the service to a given tenant, the server system attempts to access an external service due to the configuration data received from the given tenant identifying the external service. Service access errors can occur when attempting to access the external service. In response to determining that an error has occurred when attempting to access the external service, the server system sends a service access alert to a recipient associated with the given tenant. The service access alert notifies the recipient that the error has occurred.

  • Publication number: 20120062226
    Abstract: Devices and related methods for nuclear magnetic resonance (NMR) analysis of particulate materials are provided including a detector chamber configured for insertion into an NMR spectrometer and configured to receive particulate materials in a fluid. A circulation chamber is attached to and in fluid communication with a first end of the detector chamber. A transition region is between the detector chamber and the circulation chamber, and a fluid supply interface is at a second end of the detector chamber that is configured to attach to a fluid source. The detector chamber, the circulation chamber and the transition region are sized and configured such that, when fluid flows from the fluid supply interface into the second end of the detector region, a circulating current is formed in the transition region and/or the circulation chamber such that the particulate matter is contained in the circulation chamber by the circulating current.

  • Publication number: 20100186062
    Abstract: Architecture that employs encryption and storage of encryption keys to protect trusted client message content from an untrusted third-party hosted service. Each trusted user machine is configured to optionally apply security to messages. Rules determine when automatic protection is applied and the level of protection to apply. The trusted client automatically downloads the rules (or rules policies) from a trusted rules service and caches the rules locally. During composition, the rules analyze the message and automatically apply security template(s) to the message. The security template(s) encrypt the body of the message, but not the headers or subject. The untrusted message service processes the header and delivers the message to the correct recipient. The hosted service cannot view the contents of the message body, and only intended recipients of the protected message can view the message body. Offline protection is supported, and the user can override protection by the rules.
