Publication number: 20120173258Abstract: 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.Type: ApplicationFiled: January 3, 2011Publication date: July 5, 2012Applicant: athenahealth, Inc.Inventors: Matthew Hofmann, Adam Weinstein, Christopher Barnes, Kimberly Ryan, Justin Seger, Brady Richards, Joseph Holtschlag, Jeremy Delinsky

Publication number: 20120159268Abstract: 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.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Applicant: MICROSOFT CORPORATIONInventors: Jonathan LeCroy, Wilson Li, Mayank Mehta, Ayse Yesim Koman, Victor William Habib Boctor, Mayerber Loureiro De Carvalho Neto, Christopher Barnes, Frank David Byrum

Publication number: 20120062226Abstract: 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.Type: ApplicationFiled: March 31, 2010Publication date: March 15, 2012Inventors: Gary J. Pielak, Christopher Barnes, Naima G. Sharaf, Gregory Young, Freddy Pinero, Lisa Charltonl, Christopher Seagle

Publication number: 20100186062Abstract: 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.Type: ApplicationFiled: January 20, 2009Publication date: July 22, 2010Applicant: Microsoft CorporationInventors: Edward T. Banti, Frank Byrum, Mayerber L. Carvalho Neto, James R. Knibb, Palash Biswas, Christopher Barnes
