摘要： The optical coupler includes first, second and third port assemblies and a deflecting element. The first port assembly receives a first optical signal, the first port assembly including a first lensing element. The second port assembly emits a predetermined, transmitted portion of the first optical signal. The second port assembly includes a second lensing element. The deflecting element is positioned between the first and second port assemblies. The third port assembly includes a third lensing element. The deflecting element and the third port assembly are so positioned and arranged such that a deflected portion of the first optical signal is deflected from the deflecting element and directed through the third port assembly. The predetermined, transmitted portion of the first optical signal is directed through the second port assembly without being deflected by the deflecting element. The transmitted and deflected portions of the first optical signal are expanded and collimated while passing through the optical coupler by appropriate positioning of the lensing elements to provide efficient and accurate control of the first optical signal.

摘要： A variable splitting optical coupler includes a first port assembly, a second port assembly, a movable deflecting element assembly and a third port assembly. The first port assembly includes a first lensing element and receives a first optical signal. The second port assembly includes a second lensing element and emits a variable transmitted portion of the first optical signal. The movable deflecting element assembly includes a movable deflecting element positioned between the first and second port assemblies. The third port assembly includes a third leasing element. The movable deflecting element is so positionable and the third port assembly is so positioned and arranged so that a deflected portion of the first optical signal is deflected from the deflecting element and directed through the third port assembly. The variable transmitted portion of the first optical signal is directed through the second port assembly without being deflected by the deflecting element. The transmitted and deflected portions of the first optical signal are expanded and collimated, while passing through the optical coupler by appropriate positioning of the lensing elements to provide efficient and accurate control of the first optical signal. The movable deflecting element varies the relative splitting of the deflective and transmitted portions of the first optical signal.

摘要： This invention relates to fiber optic networks for the two way communication of light signals. One optic fiber may carry bidirectional signals to many nodes connected to the optic fiber by bidirectional passive optic couplers. Passive unidirectional to bidirectional passive optic couplers can bridge between bidirectional optic fiber networks and unidirectional fiber optic networks. Thus optical signals can be transported to and from each node to all other nodes such that each node is in contact with all the other nodes on the network.

摘要： Initial optical signals propagate downstream through a primary transmitting GRIN lens and a primary receiving GRIN lens that are joined at an optical interface. A secondary transmitting GRIN lens, or another type of optical device, is joined to the primary receiving GRIN lens at the optical interface, and a secondary receiving GRIN lens, or another type of optical device, is joined to the primary transmitting GRIN lens at the optical interface. Extracted optical signals are transmitted from the primary transmitting GRIN lens to the secondary receiving GRIN lens and, inserted optical signals are transmitted from the secondary transmitting GRIN lens into the primary receiving GRIN lens. The secondary GRIN lenses are angularly displaced from one another so that extracted optical signals consist solely of the information of the initial optical signals and an extracted portion of the optical energy of the initial optical signals. A composite optical signal, which propagates downstream through the receiving GRIN lens, includes the information of the initial optical signals, the unextracted portion of the optical energy of the initial optical signals, and all of the inserted optical signals. The secondary GRIN lenses are substantially smaller than the primary GRIN lenses, such that the secondary GRIN lenses have a minimal impact upon the transmission of the initial optical signals from the primary transmitting GRIN lens to the primary receiving GRIN lens.

摘要： A fiber optical "T" coupler for sending and receiving signals on the same fiber optic element to facilitate ease of building and operating fiber optic communications networks. The fiber optical "T" coupler has three GRIN lenses, a receiving GRIN lens, a transmitting GRIN lens and a focusing GRIN lens, each having a focusing end and a collimating end. The transmitting GRIN lens' and the focusing GRIN lens' collimating ends are attached to and optically connected to the collimating end of the receiving GRIN lens. Fiber optic elements can be connected to the GRIN lenses focused ends for receiving signals to be collimated or for sending focused signals from the collimated end of the GRINs. Thus a light emitting transducer sends light to the transmitting GRIN lens and through the receiving GRIN lens to a fiber optic element. The same fiber optic element brings light to the receiving GRIN lens which is optically connected to the focusing GRIN lens which focuses the light on a light detecting transducer.

摘要： An electromechanical actuator incorporates a drive housing connected to a motor for rotational motion. A screw is employed with an actuating nut having protruding engagement bosses and a drive coupling is concentrically received within the drive housing having segments equal to the number of engagement bosses. Each segment has a cavity to receive a respective one of the engagement bosses and the segments are cooperatively positionable from an active position radially compressed to engage the bosses within the cavities to a released position radially expanded to disengage the bosses from the cavities.

摘要： In an optic fiber, different first and second optical signals are transmitted through optic fiber in the first direction. The first optical signal may be infrared, whereas the second optical signal may be visible, so as to provide a visible indication that optical energy is propagating through the optic fiber. The optic fiber is connected to an optical system that includes a transceiving GRIN lens, a receiving GRIN lens and a plurality of transmitting GRIN lenses that are smaller than the receiving GRIN lens. The transceiving GRIN lens has opposite first and second ends, collimates optical signals propagating therethrough and emitted via the first end, and focuses optical signals propagating therethrough and emitted via the second end. The receiving GRIN lens has opposite first and second ends, and focuses optical signals propagating therethrough and emitted via the second end thereof. The first end of the receiving GRIN lens is optically connected to the first end of the transceiving GRIN lens such that the transceiving GRIN lens is operative for transferring collimated optical energy to the second GRIN lens. Each of the transmitting GRIN lenses has opposite first and second ends, and collimates optical signals propagating therethrough and emitted via the first end thereof. The first end of each of the transmitting GRIN lenses is optically connected to the first end of the transceiving GRIN lens such that the transceiving GRIN lens is operative for receiving collimated optical signals from each of the transmitting GRIN lenses.
