    Abstract: A power steering system incorporates a stability augmentation control program so as to provide hydrostatic power steering to the front and/or rear wheels of a vehicle. The hydrostatic steering system utilizes a control piston responsive to movement of a rack element of the rack and pinion steering connection of the vehicle steering system. A steering wheel angle sensor is connected to the steering shaft for providing an output angle signal to the steering controller and an electric motor of the system is responsive to a command signal generated by the steering controller. The steering of the wheels of the vehicle is then controlled in response to the steering wheel angle, vehicle speed and yaw rate of the vehicle. The controller receives inputs from each of the sensors so as to provide a control signal permitting stable steering control of the front wheels of the vehicle. The system is also applicable for providing steering for rear wheels of the vehicle in which a position sensor provides a control signal to the controller for controlling hydrostatic power to a control chamber for a steering rod of the rear wheels of the vehicle.

    Abstract: A hydrostatic power steering system including an electric motor is provided for a automotive vehicle. The hydrostatic power steering system utilizes a power steering piston responsive to movement of the rack element of the rack and pinion steering connection. The power steering piston is provided in a piston chamber divided by a valve land into first and second portions, each of which are connected to first and second hydraulic lines. A torque sensor is connected to the steering shaft for providing an output torque signal to a power steering controller. The electric motor of the system is responsive to a command signal generated by the power steering controller. An electrically operated valve is connected to the hydraulic lines and is adapted to receive a signal from the power steering controller for controlling flow of hydraulic fluid to the power steering chamber. The electrically operated valve arrangement is rendered inoperative within a predetermined zone defined by the command signal and the output torque signal.

    Abstract: An apparatus is provided for spectral purity transfer between a radio frequency (RF) frequency spectral domain and a terahertz (THz) frequency spectral domain. The apparatus includes a first optical frequency comb (OFC) having a first operational frequency and a second OFC having a second operational frequency different from the first operational frequency. The apparatus further includes a THz oscillator, wherein the first OFC and the second OFC are locked with one another and the second OFC and the THz oscillator are locked with one another.

    Abstract: Examples of systems and methods for integrated photonic broadband microwave receivers and transceivers are disclosed based on integrated coherent dual optical frequency combs. In some cases, when the system is configured as a receiver, the microwave spectrum of the input signal can be sliced into several spectral segments for low-bandwidth detection and analysis. In some cases, when the system is configured as a transmitter, multiple radio frequency (RF) carriers can be generated, which can be coherently added or encoded independently for transmission of individual microwave bands. In some systems, the optics-related functionalities can be achieved via integrated optic technology, for example, based on silicon photonics, providing tremendous possibilities for mass-production with significantly reduced system footprint.
