20110238167 | METHODS OF CONDITIONING SHEET BIOPROSTHETIC TISSUE - Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smoothes the surface. The wavelength, power and pulse rate of the laser are selected which will smooth the fibrous surface as well as ablate the surface to the appropriate thickness. Alternatively, a dermatome is used to remove a layer of material from the fibrous surface of the membrane. Thinning may also employ compression. Stepwise compression with cross-linking to stabilize the membrane is used to avoid damaging the membrane through inelastic compression. Rather, the membrane is bound in the elastic compressed state through addition cross-linking. The foregoing several thinning techniques may be employed together to achieve strong thin membranes. The finally thinned membrane may then be treated by capping of calcification nucleation sites and borohydride reduction. The leaflets may be formed to have more than one region of uniform thickness, such as a thicker peripheral sewing region. | 09-29-2011 |
20120071970 | PHYSIOLOGIC TRICUSPID ANNULOPLASTY RING - A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence. | 03-22-2012 |

20110018556 | PRESSURE AND TOUCH SENSORS ON FLEXIBLE SUBSTRATES FOR TOYS - A capacitive sensor comprises patterned electrodes and printed wires of conductive material integrated with sensing circuits on flexible circuit substrates. The flexible circuit substrates are fingered or otherwise elongated to distribute sensing points to the limbs in a toy doll or animal, or squares on a board game. Such sensing points can detect the presence of a finger even though actual contact is not made by measuring the proportions and changes in stray capacitance attaching to the various electrodes. Touch sensors are therefore possible even when the capacitor sensor's sensing points are covered by a doll's plastic skin or a plush animal's fur. Including an interlayer of open cell foam under the flexible circuit substrate further implements a pressure sensor because applied pressures will deform the geometries of the capacitor electrodes and dielectrics enough to produce a measurable change in capacitance. | 01-27-2011 |

Each of several physical toy states can be uniquely represented with an electronic circuit register. A multi-bit register status at any one particular instant directly represents the entire state the toy is in, and is quick and simple to inspect and act on. State changes triggered by input stimuli cause a change in the register bits reflecting the changing conditions of the toy. | 01-27-2011 |

Capacitive touch sensors are deposited on a bottom plastic film with silvered conductive inks. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film. A final overcoat of adhesive is applied to the bare backside of the bottom plastic film for final assembly to a frame or chassis. | 01-26-2012 |

20100310246 | Method for using a variable aperture to tune image quality parameters in a camera system - In a camera system with a variable aperture, variations can be used to tune a variety of optical parameters otherwise incapable of being tuned within the structural limitations of the camera system or to optimize tradeoffs between competing factors such as diffraction limits and lens aberrations. For example, the variable aperture can be used to avoid overexposure or underexposure of an image due to improper illumination of an object. The variable aperture can be used to tune hyperfocal distance, enabling an accurate focus of an object to be obtained even if the camera lens is incapable of auto-focusing.

20110187904 | Aperture shading correction - In camera systems with more than one aperture plane, light from different object points can be shaded by either the lens' pupil, the system's aperture or both. depending on pupil and aperture diameters, separation and camera system field of view. In an aperture shading correction (ASC) algorithm, the shading that results from the convolution of the lens' pupil function and its aperture function is determined over the image plane for any given pupil and aperture diameter and separation. A shading correction function is then calculated, and/or its parameters are determined, that will undo the adverse relative illumination degradations that result from the tandem pupil and aperture. This can be done in separate color planes. This can be done in tandem with standard lens shading correction that must also be corrected for (i.e., the lens shading correction (LSC) can be performed in the sensor for the case of no aperture shading, then the ASC multiples the LSC during aperture shading). Aperture shading will also impact SNR and MTF, and as such the tuning of these parameters will also benefit from ASC knowledge. | 08-04-2011 |
