| 20090192396 | Apparatus and method for detecting a fetal heart rate - An apparatus and method for detecting the heart rate of a fetus. The apparatus includes three detectors detecting heart beats of the fetus, each detector including at least two electrodes detecting ECG signals, the detectors being positioned on an abdomen of a mother in use. The apparatus also includes a processor coupled to the detectors, the processor being adapted to process the ECG signals received from the detectors and determine a heart rate of the fetus. The method of determining the heart rate of the fetus includes determining a position of the fetus within a womb, placing the detectors on an abdomen of the mother, monitoring the ECG signals obtained from the detectors for a predetermined length of time, and processing the ECG signals obtained from the detectors positioned on the abdomen of the mother to determine heart beats of the mother. | 07-30-2009 |
| 20090306487 | PHOTOPLETHYSMOGRAPHY - A photoplethysmograph device includes a light source for illuminating a target object. A modulator drives the light source such that the output intensity varies as a function of a modulation signal at a modulation frequency. A detector receives light from the target object and generates an electrical output as a function of the intensity of received light. A demodulator with a local oscillator receives the detector output and produces a demodulated output,insensitive to any phase difference between the modulation signal and the oscillator, indicative of blood volume as a function of time and/or blood composition. A number of demodulators may be provided to derive signals from multiple light sources of different wavelengths, or from an array of detectors. The plethysmograph may operate in a transmission mode or a reflectance mode. When in a reflectance mode, the device may use the green part of the optical spectrum and may use polarising filters. | 12-10-2009 |
| 20100294917 | Apparatus and Methods for Imaging - For imaging, an electromagnetic radiation sensor is used to produce an output when illuminated by a modulated laser light. In use, the output is determined by a laser Doppler signal illuminating the sensor. Various examples are described for achieving integration of on-chip processing onto the substrate providing the sensor. In one example, the output of the sensor is a logarithmic function of the illuminating laser Doppler signal. In another example, the output of the sensor is normalized. In another example, an amplifier arrangement is provided to amplify the output of the sensor, the amplifier gain being lower at DC than at the frequency range of the laser Doppler signal. In another example, a filter is integrated into the semiconductor device. In another example, a bandpass filter and frequency weighted filter are provided, and their outputs are processed to average values over time. | 11-25-2010 |

| 20150161624 | SYSTEMS AND METHODS FOR CAPTURING, MANAGING, AND TRIGGERING USER JOURNEYS ASSOCIATED WITH TRACKABLE DIGITAL OBJECTS - System and methods for capturing, managing, and triggering user journeys is provided. The system is configured to enable participating individuals (e.g., a user) to generate and deliver trackable digital objects. The digital objects can be associated with enterprises, goods, services, etc. Each object can be traced by the system over a user journey, for example, as the digital object is referred through a user's social connections, to capture rich metadata. Each interaction with the digital object can be tracked by the system and the captured data attributed to the originating user, intermediate users, among other users and entities. The system provides accurate and clear measurement of influence on any one of the originating users and downstream users who interact with the digital object. In some implementations, the tracked data can be used to trigger additional processes based on action events associated with the digital object. | 06-11-2015 |

| 20150163311 | SYSTEMS AND METHODS FOR CAPTURING, MANAGING, AND TRIGGERING USER JOURNEYS ASSOCIATED WITH TRACKABLE DIGITAL OBJECTS - Systems and methods deliver the opportunity for audience members to fully engage their contacts and combine television entertainment with social media activity that is trackable. A participant can register their “social vote” by signing up to a fan distribution campaign. The participant can share the campaign into their social networks. The act of sharing the campaign creates a trackable digital object unique to that participant that is injected into the participant's social network. As the participant's friends, connections, family, etc., interact with the trackable digital object, the activity is traceable to the participant and the participant's influence over their network can be measured and rewarded even across multiple social media channels or other distribution channels. In the social voting context, the participant can be rewarded based on the number of votes the participant collects across their social network channels, for example, as the participant's friends engage in social voting. | 06-11-2015 |
