20140347131 | SEMICONDUCTOR DEVICE AND CIRCUIT WITH DYNAMIC CONTROL OF ELECTRIC FIELD - A circuit, comprising a semiconductor device with one or more field gate terminals for controlling the electric field in a drift region of the semiconductor device; and a feedback circuit configured to dynamically control a bias voltage or voltages applied to the field gate terminal or terminals, with different control voltages used for different semiconductor device characteristics in real-time in response to a time-varying signal at a further node in the circuit. | 11-27-2014 |
20140347135 | BIPOLAR TRANSISTORS WITH CONTROL OF ELECTRIC FIELD - The invention provides a bipolar transistor circuit and a method of controlling a bipolar transistor, in which the bipolar transistor has a gate terminal for controlling the electric field in a collector region of the transistor. The bias voltage applied to the gate terminal is controlled to achieve different transistor characteristics. | 11-27-2014 |

20120255782 | SONIC DRILL HEAD - A sonic drill head comprising an outer housing, an isolation system, a sine generator and a spindle. The sine generator generates a linear sinusoidal vibration force through the rotation of a plurality of eccentric masses. The sine generator is configured to translate the linear sinusoidal force to the spindle in a direction corresponding to the spindle's axis of rotation. The sine generator supports the spindle within the housing such that the spindle is free to rotate about the spindle axis. The spindle is generally a hollow tube section thereby allowing the passage of drilling fluid, mud, cuttings, and/or tooling. The isolation system generally reduces the transfer of the vibration force generated by the sine generator to the outer housing, yet is able to transfer an applied thrust force from the outer housing to the sine generator. | 10-11-2012 |

20090256846 | SYSTEM AND METHOD OF PROVIDING INTERACTIVE DATA ANALYSIS WITH VARYING SUBJECTIVE PARAMETERS - An interactive data analysis system is disclosed. The interactive data analysis system has a computer-generated user interface which includes a plurality of histogram elements having data band controls. The data band controls allow modification of subjective parameters related to the data analysis and produce realtime updates to data forms which present the analyzed data to the user. | 10-15-2009 |

20150326462 | ADAPTIVE RATE CONTROL FOR CELLULAR-BASED VEHICULAR NETWORKS - A method for supporting vehicular communication in a cellular-based communication system includes connecting at least one base station and a plurality of vehicles equipped with mobile communication devices. A centralized control entity coordinates packet transmissions of the vehicles. Adjustment of a packet transmission rate is done recursively, where parameters of packet transmission characteristics are measured and the control entity determines, based on the parameters of packet transmission characteristics, an optimal packet transmission rate. The vehicles and/or the control entity transmit packets use the optimal packet transmission rate. | 11-12-2015 |
