摘要： A system of connecting errors in the control loop using multiple additional loops. A first loop carries out control in a desired way, and the additional loops are provided for the purpose of determining a specified error value. That specified error value may be, for example, a quiescent current. The specified error value is then used to correct for errors in the first loop.

摘要： A device structure and system for connecting optical waveguides to optical transmit and receive components is described. The structure is made of two parts. The lower part contains active optoelectronic components, such as lasers and photodetectors, and optical lenses. The lower part can be assembled by steps of aligning and bonding planar components. The upper part contains optical waveguides and lenses for coupling light into and out of the waveguides. The top part is mechanically connected to the lower part to form a mechanically sound connection. The lens system provides some tolerance to mis-alignment between the top and bottom parts. The system has features that enable fiber optic components to operate and survive in harsh environments, particularly large temperature extremes.

摘要： A component system and method is described that is made of components for transmitting, routing and receiving “in-air” optical signals for placement on printed wiring boards (PWBs). The transmitters are components including a light source attached to a transparent substrate and aligned to a coupling lens. The transparent substrate can contain circuitry for controlling the light source, or the circuitry could be attached to the transparent substrate. The receivers include a light detector attached to a transparent substrate with circuitry for converting optical signals to electrical circuitry (integrated onto the transparent substrate or separately attached). The routing components include a lens for coupling light into an optical waveguide, an optical waveguide and, optionally, a second lens for coupling light from the optical waveguide. The component system allows in-air optical communication between PWBs, without requiring traditional connections and harnesses between the PWBs, thus increasing their reliability and throughput.

摘要： A connector attachment to a low height module is described that has a lid configured with an attached spring extension that is substantially planar to the lid. At the end of the spring extension is a spring or compressing mechanism that fits over an external mechanically transferable (MT) ferrule, the ferrule being connected to a ribbon of fibers or communication lines. The external ferrule is fitted to a side of the low height profile module that has an opening to couple the communication lines to the interior/devices in the module. The connector attachment is secured to the module via screws, for example. The combination of the lid with the spring extension and spring/compressing mechanism provides for a very elegant low profile connector assembly that allows communication lines to be more robustly attached to the module than currently practiced and also preserves the overall height of the low height profile module.
