| 20090029536 | Bipolar transistors with vertical structures - A method for fabricating a bipolar transistor includes forming a vertical sequence of semiconductor layers, forming an implant mask on the last formed semiconductor layer, and implanting dopant ions into a portion of one or more of the semiconductor layers. The sequence of semiconductor layers includes a collector layer, a base layer that is in contact with the collector layer, and an emitter layer that is in contact with the base layer. The implanting uses a process in which the implant mask stops dopant ions from penetrating into a portion of the sequence of layers. | 01-29-2009 |

| 20090036902 | INTERACTIVE USER INTERFACES FOR ROBOTIC MINIMALLY INVASIVE SURGICAL SYSTEMS - In one embodiment of the invention, a method for a minimally invasive surgical system is disclosed. The method includes capturing and displaying camera images of a surgical site on at least one display device at a surgeon console; switching out of a following mode and into a masters-as-mice (MaM) mode; overlaying a graphical user interface (GUI) including an interactive graphical object onto the camera images; and rendering a pointer within the camera images for user interactive control. In the following mode, the input devices of the surgeon console may couple motion into surgical instruments. In the MaM mode, the input devices interact with the GUI and interactive graphical objects. The pointer is manipulated in three dimensions by input devices having at least three degrees of freedom. Interactive graphical objects are related to physical objects in the surgical site or a function thereof and are manipulatable by the input devices. | 02-05-2009 |

| 20080255049 | COMBINED USE OF ULTRASOUND AND GROWTH FACTORS TO STIMULATE BONE FORMATION - The combination of low intensity pulsed ultrasound with administration of an osteogenic protein or proteins or their genes enhances bone repair in mammals. This combination avoids thermal activation of tissue repair mechanisms and allows the osteogenic protein or proteins or their genes to act at the site of bone fracture or lowered bone density to enhance or accelerate bone formation, thereby improving the prognosis of a patient. The combination may be used to treat fractures, to prevent or treat osteoporosis, to improve outcomes for bone replacement and to prevent or treat bone loss due to other physiologic disorders. | 10-16-2008 |

Also, the feedback module is defined to generate a tap weight adjustment signal for a given tap weight of the FIR filter when a magnitude of a post cursor counter corresponding to the given tap weight is greater than or equal to a threshold value. An adaptation module is defined to adapt a reference voltage used to generate the reference sample signals to a condition of the differential signal. | 12-24-2009 |
