A spring system for relatively displacing elements attached to end mounts of the rod assembly comprises a housing having a rod member movable between extended and retracted positions relative thereto, and a first compression spring in the housing surrounded by a second compression spring for biasing the rod member to one of an extended or retracted position relative to the housing. The two springs are oppositely wound whereby, from a compressed condition, the spring rod exerts an expansion force which increases at a linear rate. The spring system includes a valve arrangement to control the rate at which the spring rod moves from a retracted position to an extended position.

A spring is formed of a relatively thin sheet of spring material which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. The greater the force, progressively higher the wave frequency with lower amplitude would form. When the force is removed, the flexible material returns to its original shape. The force needed to shift the curve (increase the number of waveform) increases at an exponential rate, as opposed to the linear rate of most normal springs. The maintenance force of new stable state is considerable less than the threshold force. Such a relatively flat spring with an exponential spring rate and self dampening through phase change has a number of useful applications for automotive and industrial use.

An impaired operation detection method is basically performed by sensing a yaw rate of a vehicle over a time period. Then time points are identified in which the yaw rate changes direction. A linear rate of change in the yaw rate is determined between two of the time points that are sequential in time. An actual rate of change is examined between the two time points. A difference between the actual rate of change and the linear rate of change to obtain a difference value. Then, the operator's impairment condition is determined based on the difference value.

A method for interrogating time-multiplexed interferometric sensors using multiple interrogation pulses so as to increases the allowable interrogation pulse duty-cycle and improve the signal-to-noise ratio. In each TDM repetition period a sequence of multiple interrogation pulses are generated. The pulses in the sequence are separated by a time that is equal to the sensor imbalance. The phase from pulse to pulse in each TDM time-slot is modulated at a different, linear rate such that the pulse in time-slot m will have an optical frequency that is shifted by mΔν, where Δν is the sub-carrier frequency. Because multiple reflections do not need to fade out the inventive method can enhance the signal-to-noise ratio of interferometric sensors such as inline Fabry-Perot sensors.

The invention relates to an adaptive load balancing energy consumption optimization method and system in a spectrum flexible optical network, which is designed in order to effectively improve the spectrum resource efficiency of the optical network and reduce the energy consumption of the optical network. Different linear rate and modulation format combinations are adopted for each connection request so as to bear bandwidth requirements of the connection request, and the weight of each optical fiber link is dynamically adjusted according to a distance-adaptive load balance adjustment method so as to enable the connection request to select a lightly-loaded optical fiber link to act as a transmission path. According to the invention, some short-distance optical fiber links are avoided from being selected by excessive connection requests to result in congestion, thereby improving the resource efficiency of the spectrum flexible optical network, and realizing high energy consumption efficiency.

A semiconductor diode scintillation detector probe, in conjunction with a base-line-stabilized, wide-bandwidth first amplifying circuit DC-coupled to a constrained-bandwidth second amplifying circuit DC-coupled, in turn, to a novel analog threshold discriminator circuit, suppresses base-line fluctuation and noise at low input count-rates, while providing a linear rate-meter response for time-random input pulse rates far in excess of what would otherwise—as in the prior art—be 100% saturation.

The invention belongs to the field of steel material, in particular to a preparation method for forming Ti2O3 nano particles in molten steel. The method has the following characteristics that: Fe-Ti alloy wires are added in molten low-carbon steel or low-carbon alloy steel with the oxygen concentration of less than 100PPm, so that molten steel containing O and Ti is obtained; since the alloying elements Ti and O of precipitated phase Ti2O3 higher than the melting point of matrix alloy are contained, the solubility of Ti and O reduces with the decrease of the temperature, the high cooling speed can form high supercooling degree, meanwhile, the melt can form the high linear rate of flow in the process of solidification, and thereby solidified alloy strengthened by dispersed and precipitated nano Ti2O3 is obtained. The invention has the following advantages that: nano Ti2O3 dispersed phase can be directly formed in the solidified alloy, and thereby the strength of the alloy is enhanced under the premise that the plasticity and toughness of the alloy are nearly kept unchanged.

If several sensors are provided in the pacemaker, smooth rate-responsive pacing functions may be separately generated for use with each sensor.
