20150065830 | SYSTEM AND METHOD FOR OPERATING A SENSOR FOR DETERMINING BLOOD CHARACTERISTICS OF A SUBJECT - In accordance with one aspect of the present technique, a method is disclosed. The method includes receiving continuous photoplethysmographic (PPG) data of a subject from a sensor and calculating a continuous blood characteristic (BC) based on the continuous PPG data. The method also includes calculating a first quality metric of the continuous PPG data based on a sequence of the continuous BC. The method further determines whether the first quality metric satisfies a stability criterion and sending a first notification to the sensor in response to determining that the first quality metric satisfies the stability criterion. The first notification instructs the sensor to collect compressed PPG data of the subject. | 03-05-2015 |

20110246566 | PROFILE FOR MEDIA/AUDIO USER PREFERENCES DATABASE - Systems and methods for providing a media profile that is based on receiving data from various content distributors and creating a media profile. The media profile is web-based and accessible via an API. Data can be provided to the media profile host server via the API, and an end-user's media preferences can be stored in the media profile. The media profile is accessed by content distributors such that a customized media experience may be offered to the end-user without the need for the content distributor to gather his own separate data. The media profile can also store billing information for the end-user and act as a single reputable platform to conduct financial transactions. | 10-06-2011 |

20110295974 | SEAMLESS TRANSFER OF MEDIA STREAMS - The transfer of media transmitted from a media provider from a first rendering device to a second includes establishing a network connection between the media provider and the second rendering device based on a network location and session context information. A desired transmission duplication of the media is determined such that the duplication will prevent substantial interruption of the rendering of the media as experienced by a user listening to both of the rendering devices, and that desired transmission duplication is sent to both the first rendering device and the second rendering device. The transmission is continued from the media provider to the second rendering device. | 12-01-2011 |

20110188478 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR INTERFERENCE-MINIMIZING CODE ASSIGNMENT AND SYSTEM PARAMETER SELECTION FOR CODE DIVISION MULTIPLE ACCESS (CDMA) NETWORKS - A method for interference-minimizing code assignment and system parameter selection for code division multiple access (CDMA) networks is disclosed. The method is performed at a base station or mobile station configured to operate in a CDMA radio network. The method includes receiving transmissions from user devices seeking to access the CDMA radio network. A spreading code is selected for a first user device seeking to access the network, using at least one cross-correlation parameter, to reduce multiple access interference between communications involving the first user device and other devices using the CDMA network. The method does not require knowledge of the active user codes or even the codebook from which these codes are assigned. Furthermore, it does not require knowledge of bit or chip epoch or the received powers of active users. However, the method can benefit from such knowledge in several ways, examples of which are disclosed. A method for explicitly estimating the bit or chip epoch is also disclosed. | 08-04-2011 |

20090259671 | SYNCHRONIZING TIMING MISMATCH BY DATA INSERTION - The rate at which data is provided by one device and the rate at which that data is processed by another device may differ. For example, a transmitting device may transmit data according to a transmit clock while a receiving device that receives the transmitted data may process the data according to a receive clock. If there is a timing mismatch between the transmit and receive clocks, the receiving device may receive data faster or slower than it processes the data. In such a case, there may be errors relating to the processing of the received data. To address timing mismatches such as this, the receiving device may delete data from or insert data into the received data. In conjunction with these operations, the receiving device may modify the received data at or near the insertion point or the deletion point in a manner that mitigates any adverse effect the insertion or deletion may have on a resulting output signal. | 10-15-2009 |

20140200416 | MENTAL STATE ANALYSIS USING HEART RATE COLLECTION BASED ON VIDEO IMAGERY - Video of one or more people is obtained and analyzed. Heart rate information is determined from the video and the heart rate information is used in mental state analysis. The heart rate information and resulting mental state analysis are correlated to stimuli, such as digital media which is consumed or with which a person interacts. The heart rate information is used to infer mental states. The mental state analysis, based on the heart rate information, can be used to optimize digital media or modify a digital game. | 07-17-2014 |
20140357976 | MENTAL STATE ANALYSIS USING AN APPLICATION PROGRAMMING INTERFACE - A mobile device is emotionally enabled using an application programming interface (API) in order to infer a user's emotions and make the emotions available for sharing. Images of an individual or individuals are captured and send through the API. The images are evaluated to determine the individual's mental state. Mental state analysis is output to an app running on the device on which the API resides for further sharing, analysis, or transmission. A software development kit (SDK) can be used to generate the API or to otherwise facilitate the emotional enablement of a mobile device and the apps that run on the device. | 12-04-2014 |
