Abstract: Receiver-stimulators comprise a nearly isotropic transducer assembly, demodulator circuitry, and at least two tissue contacting electrodes. Use of near isotropic transducers allows the devices to be implanted with less concern regarding the orientation relative to an acoustic energy source. Transducers or transducer elements having relatively small sizes, typically less than ½ the wavelength of the acoustic source, enhance isotropy. The use of single crystal piezoelectric materials enhance sensitivity.

Abstract: An airway implant device for maintaining and/or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The airway implant device comprises a deformable element to control the opening of an air passageway. Preferably the deformable element is an electroactive polymer element. Energizing of the electroactive polymer element provides support for the walls of an air passageway, when the walls collapse, and thus, completely or partially opens the air passageway. Some embodiments of the invention include a sensor capable of sensing the possible occurrence of an apneic event and activating the deformable element of the airway implant device. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

Abstract: A vertically conducting semiconductor device includes a semiconductor substrate having a topside surface and a backside surface. The semiconductor substrate serves as a terminal of the vertically conducting device for biasing the vertically conducting device during operation. An epitaxial layer extends over the topside surface of the semiconductor substrate but terminates prior to reaching an edge of the semiconductor substrate so as to form a recessed region along a periphery of the semiconductor substrate. An interconnect layer extends into the recessed region but terminates prior to reaching an edge of the semiconductor substrate. The interconnect layer electrically contacts the topside surface of the semiconductor substrate in the recessed region to thereby provide a topside contact to the semiconductor substrate.

Abstract: Embodiments of the present invention relate to a multifocal lens having a mostly spherical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.

Abstract: A programmable delay element, variable-length delay chain, and ring oscillator are disclosed. The programmable delay element performs phase interpolation of input signals in response to a control signal and can be used in combination with other delay elements to create a highly-modular, variable-length delay chain or ring oscillator. The ring oscillator can be used as part of a digitally-controlled oscillator (DCO) in a digital clock synthesizer to adjust the frequency and phase of a clock signal by fractional unit delay steps. Within the variable-length delay chain, some programmable delay elements can be configured to scale the delay-step of other programmable delay elements so that a plurality of step sizes can be implemented with identical delay elements. Also, variations of the delay chain generate in-phase and quadrature phase (I/Q) signals in either an end-tap or center-tap configuration.
Abstract: A computer-implemented method for generating depth-of-field effects includes receiving information specifying an input image rendered using a pinhole camera. A first set of circles of confusion associated with portions of the input image are determined based a set of parameters associated with the pinhole camera. The first set of circles of confusion are then associated with heat conductivity of a medium. The portions of the input image are blurred according to heat diffusion in the medium to generate a first output image having a first depth-of-field effect.
Abstract: The method for forming a fine pattern of a semiconductor device includes depositing a photoresist film over a semiconductor substrate having an underlying layer, performing a first exposure process using a first exposure mask to form a first photoresist pattern, the first exposure mask defining a first and a second exposure patterns, the first exposure pattern finer than the second exposure pattern, depositing a photoresist film over an entire surface of the resultant including the first photoresist pattern, performing a second exposure process using a second exposure mask to form a second photoresist pattern, the second exposure mask defining a third and a fourth exposure patterns, the third exposure pattern finer than the fourth exposure pattern and disposed between the first exposure patterns, the fourth exposure pattern overlapped with a portion of the second exposure pattern, and patterning the underlying layer using the first and the second photoresist patterns.
Abstract: Circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in a fast and efficient manner. One such texture circuit provides an increased number of bilerps for each pixel in a group of pixels, particularly when trilinear or aniso filtering is needed. For trilinear filtering, texels in a first and second level of detail are retrieved for a number of pixels during a clock cycle. When aniso filtering is performed, multiple bilerps can be retrieved for each of a number of pixels during one clock cycle.

Abstract: 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.

Abstract: Aspects of the present invention provide multifocal lenses having one or more multifocal inserts comprising one or more diffractive regions. A diffractive region of a multifocal insert of the present invention can provide a constant optical power or can provide a progression of optical power, or any combination thereof. A multifocal insert of the present invention can be fabricated from any type of material and can be inserted into any type of bulk lens material. A diffractive region of a multifocal insert of the present invention can be positioned to be in optical communication with one or more optical regions of a host lens to provide a combined desired optical power in one or more vision zones. Index matching layers of the present invention can be used to reduce reflection losses at interfaces of the host lens and multifocal insert.

Abstract: In an information processing apparatus which executes first and second threads which executes methods, the first thread transmits a stop instruction for terminating execution of the second thread to the second thread. In response to the reception of the stop instruction, the second thread terminates execution of a first method in execution and initiates execution of the second method which should be executed subsequent to the first method.
