20110012775 | Locating System - The invention provides an antenna capable of performance similar to a Yagi-Uda antenna. However, unlike a conventional Yagi Uda antenna, the antenna of the invention is implementable on a substrate and thereby provides a directional antenna capable of disposition within a slender housing such as a cellular communications device. One embodiment of the invention provides an antenna comprising a substrate including a ground plane. The ground plane comprises a base portion and a spine portion extending from the base portion along a central axis of the substrate. A driven antenna element is disposed on a portion of the substrate and coupled to the spine portion to form a first antenna dipole. At least one antenna director element is disposed on a portion of the substrate and coupled to the spine portion to form a second antenna dipole. A reflector element comprises a portion of the ground plane. | 01-20-2011 |

20100264296 | Mixed analog and digital pixel for high dynamic range readout - An improved CMOS pixel with a combination of analog and digital readouts to provide a large pixel dynamic range without compromising low-light performance using a comparator to test the value of an accumulated charge at a series of exponentially increasing exposure times. The test is used to stop the integration of photocurrent once the accumulated analog voltage has reached a predetermined threshold. A one-bit output value of the test is read out of the pixel (digitally) at each of the exponentially increasing exposure periods. At the end of the integration period, the analog value stored on the integration capacitor is read out using conventional CMOS active pixel readout circuits. | 10-21-2010 |

20130053990 | Classification System and Method - The invention relates to a system and method for analysing an activity session. Data from a monitoring device worn by a user of the system for example is received over a period of time or distance and a classification system of the invention is utilised in real time or post session to determine the activities performed by the user during the session. The data collected relates to multiple parameters monitored during the activity session. The classification system defines an activity using a set of threshold criteria for a combination of parameters and therefore identifies a particular activity performed during the activity session when a combination of monitored parameters satisfies the threshold criteria for a particular activity. Determining the activities performed in this way allows for more useful interpretation of the data which in turn leads to more effective coaching advice and feedback for the user. | 02-28-2013 |
