    摘要: A ride control system and method where the system includes first hydraulics for equalizing pressure between ride control accumulators and boom cylinder head side, and second hydraulics for providing low pressure drop connection between ride control accumulators and boom cylinder head side. When ride control is engaged, the first hydraulics equalizes pressure between ride control accumulators and boom cylinder head side to within a pressure threshold, then the second hydraulics provides the low pressure drop connection between ride control accumulators and boom cylinder head side. Ride control system can include third hydraulics for providing fluid connection between boom cylinder rod side and tank; where after first hydraulics equalizes pressure to within pressure threshold, then third hydraulics provides connection between boom cylinder rod side and tank. The ride control system can also monitor the condition of the ride control accumulators.

    摘要: A resonant photodetector assembly (10) which uses multiple reflections of light within a photodetector (20) to convert input light into an electrical signal. The photodetector (20) includes a combination of generally planar semiconductor layers including a photodetector active layer (36) where light is converted into an electrical output. The photodetector (20) further includes a first outer electrical contact layer (34) and a second outer electrical contact layer (42). A waveguide (22) is positioned on the photodetector (20) and has a waveguide active layer (26) positioned between a pair of waveguide cladding layers (24, 28), a first end (30) for receiving input light and a second end (50) for reflecting the light. A reflector (32) is positioned on the second end (50) of the waveguide (22) at an angle relative to a line parallel to the substrate (14), where the reflector (32) reflects the light received by the first end (30) of the waveguide active layer (26) towards the photodetector (20). A reflector (38) is positioned on the second outer layer (42) of the photodetector (20) and provides a reflective surface for reflecting the light within the photodetector (20).

    摘要: A method for fabricating a monolithic micro-optical component. The construction of the micro-optical components is accomplished by using standard semiconductor fabrication techniques. The method comprises the steps of depositing an etch stop layer (44) onto a semiconductor substrate (42); depositing an optical component layer (46) onto the etch stop layer (44); coating the entire surface of the optical component layer with a photoresist material; applying a photoresist mask (50) to the photoresist material on the optical component layer (46); selectively etching away the optical component layer (46) to form at least one optical column (52); forming a pedestal (54) for each of the optical columns (52) by selectively etching away the etch stop layer (44); and finally polishing each of the optical columns (52), thereby forming monolithic optical components (56). The method may optionally include the step of removing the photoresist mask from each of the optical columns prior to polishing the optical columns, as well as the step of depositing an antireflectivity coating onto each of the optical components.

    摘要: The invention relates to an optical integrated circuit microbench system for accurately aligning optical fiber and waveguides to efficiently couple energy between optical devices. This is accomplished by using the anisotropic etch characteristics of III-V semiconductor materials in two orthogonal directions. One etch direction serves to provide a channel for precise fiber-positioning; the other direction, which is orthogonal provides a reflecting surface for directing the optical energy onto optical devices.

    摘要: An interconnected apparatus for producing a low loss, reproducible electrical interconnection between a semiconductor device and a substrate includes a rod and rod receptor. The rod, generally cylindrically shaped, is attached to the semiconductor device and includes an outer circumferential wall which comes into contact with the rod receptor during a bonding process. A lip portion is formed on one end of the rod receptor for interlocking engagement with the rod. The rod receptor is plated on the substrate and includes a generally circularly shaped body which forms a centrally disposed well for receiving the rod. A lip portion is formed on one end or mouth of the rod receptor for interlocking engagement with the rod. When the rod and corresponding receptor are aligned and brought together, the rod deforms and interlocks with its corresponding rod receptor. A thermo-compression bonding process is utilized to bond the rod to the rod receptor, thereby producing a strong interlocking bond.
