20140233437 | Frame Structure for Filter Bank Multi-Carrier (FBMC) Waveforms - A unified frame structure for filter bank multi-carrier (FBMC) and orthogonal frequency division multiplexed (OFDM) waveforms may allow FBMC and OFDM frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an FBMC frame duration to an integer multiple of an OFDM frame element duration to enable alignment of FBMC frames and OFDM frames in the time domain. The unified frame structure may also map control channels in the FBMC and OFDM frames to common resource locations so that the respective control channels are aligned in the time and/or frequency domains. The unified frame structure may also share synchronization channels between FBMC and OFDM frames. Additionally, overhead in an FBMC time division duplexed (TDD) communications channel can be reduced by overlapping time windows appended to FBMC blocks. | 08-21-2014 |
20140233664 | System and Method for Orthogonal Frequency Division Multiplexing-Offset Quadrature Amplitude Modulation - A method for performing orthogonal frequency division multiplexing (OFDM)/offset quantization amplitude modulation (OQAM) includes obtaining a data burst. The method includes performing weighted circularly convolved filtering modulation on the data burst to produce an output signal. The method further includes a first wireless device transmitting the output signal to a second wireless device. The second wireless device receives an input signal from the first wireless device, and the second wireless devices performs weighted circularly convolved demodulation filtering on the input signal to produce the data burst. | 08-21-2014 |

20150039122 | DEVICE, SYSTEM AND METHODS FOR AUTOMATIC DEVELOPMENT AND OPTIMIZATION OF POSITIONING PATHS FOR MULTI-AXIS NUMERICALLY CONTROLLED MACHINING - Optimized positioning paths for multi-axis CNC machining can be generated based on the machine tool kinematics, machine axes travel limits, machine axis velocity and acceleration limits, and machine positioning methodologies. Machine axes travel limits and machine positioning methodologies are incorporated in order to ensure that the developed positioning paths do not violate machine axes travel limitations. Multi-axis positioning paths are developed to avoid collisions with dynamically changing in-process stock and other surroundings, including fixtures and both moving and non-moving components of the machine. Positioning tool path customizations give the user the flexibility to apply safety based constraints to the automatically generated tool paths. The disclosed automatic positioning path planning and optimization methods are used to develop a process for part manufacturing using CNC machining in order to reduce the manufacturing cycle time. | 02-05-2015 |

20100275937 | HUBBLE-BUBBLE DEVICE - The various embodiments herein provide an efficient head for hubble-bubble device used in smoking and using tobacco with the capability of immediate tobacco replacement and easy regulation of the distance between charcoal and tobacco. A hubble-bubble device comprises the holder, the charcoal container arranged on top of the holder and the tobacco tray arranged on a bottom section of the holder. The tobacco tray is in the form of a drawer which provides for insertion and removal of the tobacco tray from the holder thereby facilitating quick replacement of the tobacco. | 11-04-2010 |
20120255566 | AIR SUCTION DEVICE FOR A SMOKING APPARATUS - The various embodiments herein provide an air suction device for a smoking apparatus. The air suction device comprises a cylindrical housing, an impeller, an impeller cover, a motor assembled inside the housing to drive the impeller, a plurality of batteries provided in the housing, a battery cover to enclose the plurality of batteries and a switch provided externally to the cylindrical housing. When the switch is in ON condition, the plurality of batteries supply an electrical power to the motor and the motor converts the electrical power into a mechanical power which in turn causes propulsion of the impeller thereby sucking out the air from a water bowl of the smoking apparatus. The propulsive motion of the impeller sucks out the air from the water bowl until the air inside the water bowl is replaced by condensed smoke. | 10-11-2012 |
