Abstract: A low force actuator that is used in conjunction with semi-active and passive suspension systems to provide for improved suspension and ride control for vehicles, and which overcomes stiction and provides limited active capability. The low force actuator is sized to counter the small, high frequency forces (caused by road input disturbances and stiction effects) that act on, or are transmitted between sprung and unsprung masses of the vehicle. The present invention provides for two low force actuators. The first comprises a proof mass low force electromagnetic actuator that may be connected to either the sprung or unsprung mass. In either configuration the proof mass provides an extra degree of freedom for the suspension system that decouples ride and holding control actions of the vehicle. The second comprises a differential force actuator that uses an electromagnetic actuator to provide a force between the sprung and unsprung masses of the vehicle.

Abstract: A garment pocket reinforcement including a trapezoidally shaped insert having a bottom edge, a substantially straight side edge, a sloped side edge, a first shoulder edge, a second shoulder edge and a semi circular transitional edge. The first shoulder edge and the second shoulder edge of the insert are respectively sewn to a right shoulder seam and a left shoulder seam of a shirt. The bottom edge of the insert is sewn to the back side of a pocket disposed on the shirt. The insert further includes a transitional band of material which is used to attach the semi-circular transitional edge of the insert to a collar of the shirt along the front half of the neck line. The shoulders of the shirt also include small arches which are taking up on both front and back sides of both the right and left shoulder seems.

Abstract: A fibrin glue dispenser including a spring biased rack. The rack spring is a coil spring having substantially linear characteristics along its operating length. The rack spring forces first and second plungers into first and second loaded syringes to dispense thrombin and fibrinogen into first and second exits such that the admixture of the two occurs for forming fibrin glue away from the exists. A dispensing lever can be controlled as to the fibrin glue formation to dispense either drops of fibrin glue or an elongate line of fibrin glue.

Abstract: A sprayer for dispensing fibrinogen and thrombin to form fibrin glue immediately away from the sprayer to prevent clogging and insure accurate precise metering. The sprayer includes a pistol grip area, a barrel and a trigger which moves a plunger support that captures the plunger of a syringe. One syringe holds thrombin and the other syringe holds fibrinogen. Each syringe communicates with an outlet having an atomizer.

Abstract: A compensator that enables an adaptive filter to be placed within a closed loop control system so as to reduce the effects of both measurable and unmeasurable disturbances on the output of the control loop. The disturbances may have spectra that lie within or outside the bandwidth of the control loop. The effectiveness of the reduction is dependent upon the capabilities of the loop actuator and/or the control electronics. The reduction is not limited only to the bandwidth of the control loop, as in conventional disturbance rejection, and is equally effective against feedback path disturbances which are unreduced in conventional approaches. A further aspect of the invention relates to a reduction of an intrinsic noise floor associated with control systems, including open loop and closed loop control systems, that does not require an independent noise measurement to be made.

Abstract: A system and method for determining the speed of a vehicle independent of angular wheel rotation rates is provided. The system generates time-varying signals corresponding to the vertical acceleration of the front and rear wheels. The front and rear wheel signals include corresponding perturbations caused by the wheels crossing road disturbances such as bumps. A time lag occurs between perturbations in the rear wheel signal and corresponding perturbations in the front wheel signal. An adaptive algorithm correlates the signals for various time delay values until a time delay value is determined which maximizes the correlation between the two signals. The calculated time delay value corresponds to the actual time lag between the front and rear wheels occurring before the rear wheels encounter a road disturbance previously encountered by the front wheels. Thus, the invention provides a determination of the actual speed of the vehicle determined independently from the angular rotation rates of the wheels.

Abstract: An adaptive noise cancellation system reduces undesired noise in a closed loop control system by injecting an adaptively constructed noise cancellation signal at an appropriate point in the closed control loop. The generation of a compensation filter N for adaptive noise cancellation loop error signal is disclosed by two methods. A first method is an inverse error rejection response (IERR) method. A second method optimally matches spectrums of a noise signal and a noise reference signal at the adaptive noise cancellation system. This second method is referred to as a spectral matching (SM) method.
