Patent number: 8659998Abstract: An application and audio driver communicate audio data via a ring buffer using a system interface. An application reads or writes data from the buffer in a unit of data. Positions within the buffer correspond to a particular time. To write data to the buffer at a particular position in the buffer that corresponds to a particular time, an application is awaken a period of time (“client-side offset”) before the driver reaches the position. The period of time is computed based on a variety factors. One factor is the amount of time the system interface assumes an application uses to write the unit of data to the buffer. For operations that entail the application inserting data into the buffer, the application may specify a weight value to apply to the factor to reduce it and the latency period.Type: GrantFiled: July 28, 2010Date of Patent: February 25, 2014Assignee: Apple Inc.Inventors: Jeffrey C.

Publication number: 20120272967Abstract: A facemask structure for inactivating pathogens includes a facial contact layer that is benign to human skin followed by a subsequent interior layer and an outer layer including an anti-pathogenic material. In this manner, active, isolated anti-pathogen layers can be provided in a multilayer mask structure. For example, an important anti-viral mask structure uses one or a mixture of acids to create a low pH environment on the first inner (or outer hydrophilic layer) so that the virus laden droplets from, e.g., a sneeze, are absorbed into and away from the surface. Thus, for an infected wearer, two or more hydrophilic layers on the interior of the mask can protect the environment from an infected wearer.Type: ApplicationFiled: March 2, 2012Publication date: November 1, 2012Applicant: Filligent LimitedInventors: Neal George Stewart, Melissa Mowbray-D' Arbela, Dacey J.

Patent number: 7806202Abstract: In an underbalanced drilling system and method, a change is induced in flowing bottom hole pressure in a wellbore. Data of the surface flow rate of effluent is then measured in response to the induced change. This measured data is obtained using a multi-phase flow meter before a separator of the underbalanced drilling system. Algorithms in computer software analyze the flowing bottomhole pressure and the measured surface flow rate data and determine both permeability and formation pressure for a portion of the wellbore in real-time during the underbalanced drilling operation. Ultimately, portion of the wellbore is characterized with the determined permeability and formation pressure.Type: GrantFiled: February 27, 2008Date of Patent: October 5, 2010Assignee: Precision Energy Services, Inc.Inventor: George Stewart
