Abstract:
An organic light emitting device (OLED) is disclosed for which the hole transporting layer, the electron transporting layer and/or the emissive layer, if separately present, is comprised of a non-polymeric material. A method for preparing such OLED's using vacuum deposition techniques is further disclosed.
Abstract:
A donor/acceptor-organic-junction sheet employed within an electronic memory array of a cross-point diode memory. The donor/acceptor-organic-junction sheet is anistropic with respect to flow of electrical current and is physically unstable above a threshold current. Thus, the volume of the donor/acceptor-organic-junction sheet between a row line and column line at a two-dimensional memory array grid point serves both as the diode component and as the fuse component of a diode-and-fuse memory element and is electrically insulated from similar volumes of the donor/acceptor-organic-junction sheet between neighboring grid point intersections.
Abstract:
The present invention provides a method of manufacturing VCSELs which involves a flip-bonding process wherein the top surface of the VCSEL wafer is bonded face down onto a surrogate substrate. The process begins in a manner similar to traditional double dielectric stack based VCSEL, but then involves flip-bonding the wafer onto an In or Ag epoxy coated surrogate substrate. The InP substrate is then selectively etched. After flip-bonding the wafer fabrication proceeds on the freshly etched surface which now forms the top surface. Next, standard mesa-isolation and contact formation techniques are performed on this newly etched surface.
Abstract:
A monolithically integrated vertical twin-waveguide structure reduces the sensitivity of the device performance characteristics due to the laser cavity length and variations in the layer structure. This is achieved by the introduction of an absorption or loss layer between the active and passive regions. This layer eliminates the propagation of the even mode, while having minimal effect on the odd mode. The threshold current densities and differential efficiencies of the devices are unaffected by the loss layer. A coupling efficiency of 45% from the laser to the external passive waveguide is obtained.
Abstract:
A toothbrush has a swivel mounted vacuum cup on the end of the handle which is remote from the bristles so that, when stored, the brush hangs down under gravity in a sanitary position.
Abstract:
A device includes a three-dimensionally curved substrate, a patterned metal layer disposed on the curved substrate, and an array of optoelectronic devices, each optoelectronic device including an optoelectronic structure supported by the curved substrate. Each optoelectronic structure includes an inorganic semiconductor stack. The device further includes a set of contact stripes extending across the curved substrate, each optoelectronic structure being coupled to a respective contact stripe of the set of contact stripes. The array of optoelectronic devices is secured to the curved substrate via a bond between the patterned metal layer and the set of contact stripes.
Abstract:
A system and method are disclosed that include a bridge that translates non-coherent transactions, which are received from a non-coherent subsystem, into one or more coherent transactions to be issued to a coherent subsystem. The bridge also buffers data coherently in an internal cache, also known as a proxy cache, based on certain attributes of the non-coherent transaction. The invention may be applied to any cache, which receives read and write transactions that become coherent transactions.
Abstract:
A microfluidic device for use with a microfluidic delivery system, such as an organic vapor jet printing device, includes a glass layer that is directly bonded to a microfabricated die and a metal plate via a double anodic bond. The double anodic bond is formed by forming a first anodic bond at an interface of the microfabricated die and the glass layer, and forming a second anodic bond at an interface of the metal plate and the glass layer, where the second anodic bond is formed using a voltage that is lower than the voltage used to form the first anodic bond. The second anodic bond is formed with the polarity of the voltage reversed with respect to the glass layer and the formation of the first anodic bond. The metal plate includes attachment features that allow removal of the microfluidic device from a fixture.

Abstract:
The present invention is directed to a an organic imaging device having organic detectors on a curved surface. The device may be used for imaging applications such as photography, lightweight camera systems, very high-resolution imaging, lightweight “night vision”, robotic vision, and others. A concave housing with a deformable lens is provided. The deformable lens allows for a range of fields of view and focal lengths. The invention may be configured to detect a range of electromagnetic radiation. It may then provide input to a computer, display, or other device for processing or display of the detected radiation as an image.
