A mobility extended telecommunications application and method of use which comprises an integrated wireless and wirelined network with central control and which has a programmed interface to translate between the different protocols of the wireless and the wirelined networks to allow for customized services to be furnished to said wireless network without the necessity of expensive switching and data handling devices. The application can be utilized between many networks, such as enterprise networks, and facilitates the utilization of the architecture of the wirelined network and the home location register of the wireless network for various applications on the wireless network. Moreover, the present invention also allows use of events broadcast via mass media means to modify routing of calls placed from a wireline or wireless based phone.

Mobility extended telephone application programming interface and method

A system and method for using active algorithmically controlled sensing (1a, 1b) and speaker (2a, 2b) for controlling noise from a distributed noise source (5) within an enclosure (6) with a multiple input, multiple output controller (7).

Active acoustical controlled enclosure

An actively controlled mount system to control vibration which permits static forces from a machine while decoupling the transmission of dynamic vibrational forces. The mount system provides a reduction of force losses from a first generating area to a second force applying area to actively control vibrations of a vibrating element. These force losses are minimized due to minimization of the mass and velocity of fluid pumped by pumping the fluid through short large cross-sectional area passageways. The device provides for channeling of the forces to the vibrating element in a uniaxial direction and constrains the application of forces in non-working directions.

Integrated hydraulic mount for active vibration control system

An actively controlled mount system to control vibration which permits static forces from a machine while decoupling transmission of dynamic vibration forces. The mount system includes opposed force chamber (156, 160) with pistons which control movement of an engine connected bushing (3) to allow compensatory force generated by the opposed chambers to transfer thereto to attenuate vibration from the engine.

Dual chambered, active vibration damper with reactive force producing

An active high transmission loss panel for quieting either one or two way sound radiation which incorporates a number of cells (11) which contain sensors and actuators (12) adapted to be controlled independently or interactively so as to attenuate noise attempting to pass through said panel.

Active high transmission loss panel

An active force cancellation system adapted to contain vibrations in flexible structures which utilizes co-located vibration sensors and counter-vibration devices to offset linear disturbances without setting off sub-structure vibrations.

Active force cancellation system

A mount assembly is provided for mounting a component, such as an engine, to a vehicle for active control of vibration. The assembly includes first and second mounting members and, an intermediate insert with first and second elastomeric systems connecting said first and second mounting members with the intermediate insert in between. An actuator in parallel with said first elastomeric system provides vertical force to said first elastomeric system to provide a relatively soft vertical rate. A controller operates the actuator in response to sensed vibration so that the vertical force tends to avoid or cancel it. A relatively high fore/aft and lateral dynamic rate of the first system protects the actuator. The second elastomeric system connects the second mounting member with the intermediate insert and exhibits a relatively high vertical rate and a relatively soft fore/aft and lateral rate. One or more sensors feeds data to a controller that analyzes the vibrations to determine the harmonics thereof. The controller then constructs one or more output waveforms and feeds them to the actuator so that a force is applied across the first elastomeric system between the first mounting member and the intermediate insert, thereby tending to produce the relatively soft vertical rate for component isolation and noise suppression.

Component mount assembly providing active control of vehicle vibration

A hybrid type vibration isolation mounting apparatus for supporting a first member at a second member, and including a passive vibration absorbing device, such as a typical rubberized engine mount, located between the first and second members, and an active vibration actuator for applying counter vibration isolation forces in parallel in response to the detected relative vibration of the first and second members, wherein the actuator is located on a support mount frame attached to the second member. The support mount frame provides a structure for the actuator force application, with continuous transfer of static loads between the first and second member being provided by the passive device. In its preferred embodiment, the apparatus is utilized in conjunction with vehicle engine mounts wherein the first member comprises the engine and the second member comprises the vehicle frame.
