Patent number: 7883520Abstract: Corneal epithelial pocket formation systems include a cutting head and a blade coupled to the cutting head. The blade is coupled to the cutting head at an orientation that is effective in maintaining a viable separated pocket defining portion of corneal epithelium of an eye of a patient during formation of a corneal epithelial pocket of the eye. The blade includes a cutting edge surface at its distal end. The cutting edge surface is effective in separating the corneal epithelium from the underlying Bowman's membrane of the eye without leaving residual corneal epithelial cells in contact with Bowman's membrane that may result in corneal epithelial cell growth between a corneal implant located in the corneal epithelial pocket and the underlying Bowman's membrane. Versions of the present systems include spring loaded blade holders, which may be removable from the cutting head. Versions also can include applanators.Type: GrantFiled: March 29, 2007Date of Patent: February 8, 2011Assignee: ForSight Labs, LLCInventors: Markus Gaeckle, Helmut Maas, Daniel Wolf, Tanja Riehl

Patent number: 7883471Abstract: Minimally invasive methods, systems and devices are provided for qualitatively and quantitatively assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding bronchus of the target compartment. The feeding bronchus is occluded by the catheter and a variety of measurements are taken with the use of the catheter in a manner which is of low risk to the patient. Examples of such measurements include but are not limited to flow rate, volume and pressure. These measurements are used to determine the presence of collateral ventilation and to quantify such collateral ventilation.Type: GrantFiled: December 7, 2005Date of Patent: February 8, 2011Assignee: Pulmonx CorporationInventors: Nikolai Aljuri, Anthony Wondka, George Surjan, Kirk Davis, Peter Soltesz, Rodney C.

Patent number: 7885879Abstract: To protect a person with a property interest in real property against a loss of market value thereof, a base market value of the real property is determined at a current time when the property interest in the real property arises or thereafter, and a number of types of events that cause the real property to lose market value as compared with the base market value are defined. A number of the defined types of events are selected, and a real estate market value policy is issued to the person at about the current time. The policy promises to compensate the person for any loss experienced by the person if the real property loses market value as compared with the base market value based on any of the selected types of events.Type: GrantFiled: August 15, 2008Date of Patent: February 8, 2011Assignee: United Services Automobile Association (USAA)Inventor: Arthur Quentin Smith

Patent number: 7885434Abstract: At least one wrong template for storing features of pattern information imaged on condition unsuitable for biometric authentication is provided and the wrong template information is collated with collation template information produced by extracting features from biometric information when authentication information is registered. When similarity is low, the collation template information is stored in an authentication template. The collation template is collated with the wrong template upon authentication and when similarity is high, authentication processing is not made. Further, when similarity of the collation template information and the wrong template information is high, a guidance message for solving a problem is displayed to the user. Thus, reduction of authentication performance is prevented.Type: GrantFiled: March 16, 2007Date of Patent: February 8, 2011Assignee: Hitachi, Ltd.Inventors: Keiji Kitane, Yasushi Aoyama, Harumi Satou, Shuichi Uchiyama

Patent number: 7884826Abstract: Methods and apparatus are disclosure for maintaining realistic grooming of simulated objects. In a method for simulating objects, a reference shape associated with a simulated object is received. A predetermined orientation is also received. A force acting on the simulated object is then modified based on the predetermined orientation. The force acts on the simulated object to shape the simulated object according to the reference shape. The force may be “strategically weakened” when the simulated object (or a portion thereof) is substantially aligned with the predetermined orientation. In a further method for simulating objects, a measured height associated with the simulated object is received. A “lifting” force is generated to reduce a difference between the measured height and a predetermined height associated with the reference shape. The lifting force simulates structure and internal forces that provide volume and shaping to physical objects, such as hair.Type: GrantFiled: May 25, 2007Date of Patent: February 8, 2011Assignee: PixarInventor: David Baraff
