20150348229 | Image annotation using a haptic plane - During an analysis technique, a three-dimensional (3D) image of a portion of an individual is transformed to facilitate accurate determination of detailed annotation of an anatomical structure (such as: specifying the size of the anatomical structure based on annotation markers, an orientation of the anatomical structure, a direction of the anatomical structure and/or a location of the anatomical structure). In particular, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after information specifying the detailed annotation in the 2D plane is received, the 3D image is translated and rotated back to the initial position and orientation. | 12-03-2015 |

20140043101 | Method and Apparatus for a Class-E Load Tuned Beamforming 60 GHz Transmitter - The class-E amplifier can be tuned to pass only the fundamental frequency to the antenna by optimizing the second harmonics at the drain of the final PA driver transistor. A CPW in series with a capacitor between the PA transistor and the load forms a band pass filter that only allows the fundamental frequency to pass to the load of the antenna. A supply inductor to couple the drain of the final PA driver transistor to the power supply is tuned at the second harmonic with the parasitic capacitance of the drain of the PA transistor. A load capacitance is adjusted at the fundamental frequency to insure that the current waveform and voltage waveforms at the drain of the PA driver transistor do not overlap, thereby minimizing the parasitic power dissipation and allowing maximum energy to be applied to the antenna. | 02-13-2014 |
20140043104 | Method and Apparatus for a Clock and Signal Distribution Network for a 60 GHz Transmitter System - Herein is presented, a low power on-die 60 GHz distribution network for a beamforming system that can be scaled as the number of transmitters increases. The transmission line based power splitters and quadrature hybrids whose size would be proportional to a quarter wavelength (˜600 μm) if formed using transmission lines are instead constructed by inductors/capacitors and reduce the area by more than 80%. An input in-phase I clock and an input quadrature Q clock are combined into a single composite clock waveform locking the phase relation between the in-phase I clock and quadrature Q clock. The composite clock is transferred over a single transmission line formed using a Co-planar Waveguide (CPW) coupling the source and destination locations over the surface of a die. Once the individuals the in-phase I and quadrature Q clocks are required, they can be generated at the destination from the composite clock waveform. | 02-13-2014 |

20110083122 | METHOD AND SYSTEM FOR MASSIVE LARGE SCALE TEST INFRASTRUCTURE - An automated system is provided to support massive scale grid of machines in a rapid, multi-developer coding environment. The system has virtual testing environments that are created from template machines, supporting various software versions for various code branches. The grid is built by having a small subset of template machines (e.g. with Oracle 9g, 10g, and application server installations), images of the template machines, virtual machine instances created by applying one or more of the image templates, which then are used by the virtual testing environment. Upon receipt of code changes, changes are checked-out, compiled, tested on various test feeds on a virtual testing environment, which is destroyed and re-created after every test run. Any software version upgrades or bug fixes need to be applied only to the template machines. The number of virtual machines associated with any particular template machine is dynamically configurable to provision for optimal use of testing machines. | 04-07-2011 |

20130054497 | SYSTEMS AND METHODS FOR DETECTION OF SATISFICING IN SURVEYS - Response data relating to a plurality of responses to a survey is received. The survey comprises a plurality of questions. The response data for each of the plurality of responses comprises a plurality of answers to at least a subset of the plurality of questions. A questionnaire response model is created using the response data. It is then determined, for each questionnaire response, a respective probability that the respective questionnaire response represents satisficing, such that where the respective probability exceeds a threshold, the respective questionnaire response is identified as an outlier, and where the respective probability does not exceed the threshold, the respective questionnaire response is identified as an inlier. A representation of each questionnaire response is output, each respective representation reflecting the likelihood that the respective response to which the respective representation represents satisficing. | 02-28-2013 |
20140039981 | SYSTEMS AND METHODS FOR DETECTION OF SATISFICING IN SURVEYS - A system can include a satisfication detection server to receive from a network-enabled device questionnaire responses corresponding to an online questionnaire. The satisfication detection server can determine for each questionnaire response a probability that the questionnaire response represent satisficing. The satisfication detection server can also output a data file that includes results of the determining. A satisfication detection database can store the data file. | 02-06-2014 |
