| 20080241793 | Dental Implant With Improved Osseointegration Features - Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration. | 10-02-2008 |
| 20090011384 | DENTAL IMPLANT FOR A JAW WITH REDUCED BONE VOLUME AND IMPROVED OSSEOINTEGRATION FEATURES - A dental implant has a body with a porous metal portion for engaging bone. The porous metal portion has an outer coronal to apical height and an outer diameter. Both the height and diameter are about 4 mm to about 6 mm. This permits the implant to be placed on a jaw with a reduced bone volume. | 01-08-2009 |
| 20090061388 | DENTAL PROSTHETIC DEVICE WITH SOFT TISSUE BARRIER PROMOTION MATERIAL - A dental prosthetic device has a body with a soft tissue engagement region formed of porous metal and that defines pores for the ingrowth of soft tissue into the pores. In one form, the porous metal includes tantalum. The porous metal may be partially filled with a resorbable material. The body may have a coronal end portion with an esthetic material. | 03-05-2009 |
| 20100003638 | MODULAR IMPLANT WITH SECURED POROUS PORTION - A modular implant includes a head, an intermediate part configured to engage bone, and an initially separate anchor configured to engage the head so that at least the head and the anchor cooperatively secure the intermediate part on the implant to form the modular implant. At least one of the head, the intermediate part, and the anchor has a plurality of forms, and each form is configured to be assembled on at least one form of the other two of the head, intermediate part, and anchor. The intermediate part may include a porous metal such as tantalum. | 01-07-2010 |
| 20100311028 | Dental Implant Surgical Training Simulation System - A bone implant surgery system is used for simulating a dental surgical procedure having a display that shows placing a simulated bone implant at a simulated implant site on a living body by using a simulated surgical tool holding the simulated bone implant. At least one hand-held haptic device is used to control the surgical tool and at least one controller is specifically configured to cause movement of the surgical tool on the display based on motions of the haptic device and to cause haptic feedback to a user holding the haptic device depending on the position of the surgical tool on the display. A user may then review and evaluate the results of the surgical simulation. | 12-09-2010 |
| 20110008754 | Patient-Specific Implants With Improved Osseointegration - A patient-specific bone implant has a porous body with a core material covered with tantalum. It is made with unique outer dimensions selected to match a specific patient. | 01-13-2011 |

| 20100320986 | SWITCHING CONVERTERS WITH EFFICIENTLY-CONTROLLED MODE TRANSITIONS - Efficiently controlled converter system embodiments are provided to operate in different operational modes. In a first operational PWM mode, first and second transistors are switched with a feedback-controlled duty cycle to thereby realize an inductor current that maintains a system output voltage. In a second operational PFM mode, after the output voltage decays to a lower threshold over a decay time, the control and synchronous transistors are driven a sufficient number of times to raise the output voltage to an upper threshold. The systems are controlled to efficiently transition between the first and second operational modes. For example, a converter system preferably transitions to the second PFM operational mode when current peaks of the inductor current drop below a predetermined current threshold and the system preferably transitions to the first PWM operational mode when the output voltage drops to a predetermined reference voltage. | 12-23-2010 |

| 20100028166 | SUBMERSIBLE PUMP WITH INTEGRATED LIQUID LEVEL SENSING AND CONTROL SYSTEM - In accordance with one embodiment of the present invention, there is provided a submersible pump that includes a pump housing forming a main compartment for receiving a pump impeller and having liquid entrance and exit openings in said main compartment, and an impeller mounted in the main compartment. The pump housing is adapted for submersion in a body of liquid whose level is to be controlled, and a sealed auxiliary compartment is formed as an integral part of the housing and located to be at least partially submerged in the liquid body. A drive motor is coupled to the impeller for rotating the impeller to eject liquid from the main compartment through the exit opening. An electric-field sensor is mounted in the sealed auxiliary compartment for detecting the elevation of the surface of the liquid body adjacent the sealed auxiliary compartment. At least one controllable switch is connected in the power supply line for controlling the supply of power to the drive motor, and the electric-field sensor is connected to the controllable switch for opening and closing the switch in response to changes in the detected elevation of the surface of the liquid body adjacent the outer surface of the sealed auxiliary compartment. | 02-04-2010 |

| 20090141235 | Control of Myopia Using Contact Lenses - Devices and methods for controlling myopia are provided. The devices and methods relate to the inventors discovery of the relationship between near work, the forces applied to the eye by the eyelids and myopia. The devices include a contact lens comprising a region that disperses force applied to the eye by an eyelid. The devices also include a device designed by measuring first wavefront aberrations of an eye before pre-near work and measuring second measured wavefront aberrations of the eye post-near work. The methods include a method for controlling myopia including identifying optical changes associated with near work and correcting the optical changes with an optical device. | 06-04-2009 |

| 20080213730 | TOOTH WHITENING DENTAL TRAY AND METHOD OF USE - A dental tray with a hydrophobic tooth whitening formulation where the tooth whitening formulation is substantially non-water soluble, and a method of using this dental tray to whiten the teeth. The tooth whitening formulation is primarily comprised of a hydrophobic polymer and a peroxide or a peroxide yielding compound. Preferably the hydrophobic polymer is the condensation product of a silicone resin and an organosiloxane. The dental tray is formed to encompass the front and the rear surfaces of the teeth. The dental tray is comprised of a thermoplastic or thermoset polymer. The teeth whitening formulation is placed into the dental tray and the tray placed against the teeth to be whitened. This is for a sufficient period of time to at least partially whiten teeth. This can be a period of time from about 0.5 hour to 2 hours or more. The substantially non-aqueous tooth whitening formulation is effective over a longer period of time since it is not significantly diluted or removed from the dental tray during the treatment time. | 09-04-2008 |
