    摘要: A laser (22) and detector (24) integrated on corresponding epitaxial layers of a single chip (20) cooperate with on-chip and/or external optics (62) to couple light of a first wavelength emitted by the laser to a single external device such as an optical fiber (60) and to simultaneously couple light of a different wavelength received from the external device to the detector to provide bidirectional photonic operation. Multiple lasers and detectors may be integrated on the chip to provide multiple bidirectional channels.

    摘要: A semiconductor chip has at least two DFB etched facet laser cavities with one set of facets with AR coatings and a second set of etched facets with HR coatings that have a different relative position with respect to the gratings. This creates a difference in the phase between each of the etched facets and the gratings which changes the operational characteristics of the two laser cavities such that at least one of the lasers provides acceptable performance. As a result, the two cavity arrangement greatly improves the yield of the fabricated chips.

    摘要: A steering system for a vehicle is provided that includes a steering knuckle which is rotatable about an axis. The steering knuckle includes an upper attachment point and a lower attachment point. The attachment points define the steer axis. A rotational drive unit is connected to the steering knuckle for rotating the steering knuckle about the steer axis. A control module receives a steering input corresponding to the desired Ackerman angle and commands the rotational drive unit to rotate the steering knuckle about the axis to the desired Ackerman angle. Rotational drive units for each side of the vehicle ensure that the wheels are turned to the appropriate Ackerman angle for each wheel. The rotational drive unit may include an electric motor, or a pneumatic or hydraulic pump. In one preferred embodiment, the rotational drive unit includes a fluid housing and the shaft connected to the steering knuckle. The shaft includes a vane extending therefrom and into the housing. The fluid pump pumps fluid into the housing to rotate the vane with the shaft and steering knuckle about the axis in response to a command from the control module.

    摘要: A knuckle includes a spindle to support a wheel and upper and lower bosses extending inwardly of the spindle. The lower boss includes a tie rod arm mount interface. A tie rod arm is received within the tie rod arm mount interface and a steer arm is positioned on an opposite side of the knuckle from the tie rod arm. The steer arm is fixed to the tie rod arm and includes an input mount interface to receive steering input to turn a wheel. The steer arm and tie rod arm are attached to each other with at least one fastener, or can be integrally formed together as a single-piece component.
