Abstract: A rotating grooming brush comprising a brush hub having grooming elements and shroud elements, and method for grooming a surface having an unwanted material thereon. The elements extend from the brush hub and may be positioned near its outer periphery. The elements may be grooming elements forming an array and shroud elements forming a shroud array. A rigid or elastomeric shroud extending from the brush hub surface may optionally be included about the edge of the brush hub, to the outside of the grooming elements. Rotation of the grooming attachment brush causes a low pressure region to build in the central area of the brush. This low pressure region creates a resulting force that forcefully attracts the grooming attachment brush to the surface to be groomed. The resulting force is controlled by the diameter of the brush hub, arrangement, of the elements and the speed of rotation.

Abstract: A free space optical receiver comprising a photodetector and a fiber bundle. The fiber bundle comprises a plurality of optical fibers splayed apart at one of their ends to receive free space optical energy from multiple directions. The splayed apart ends of the plurality of optical fibers may create a hemispherical shape. Each of the plurality of optical fibers has an acceptance cone for which it couples optical energy into the splayed end of the optical fiber. The acceptance cones of the splayed ends of the plurality of optical fibers may overlap to form an omnidirectional acceptance zone. The other, non-splayed ends of the plurality of optical fibers are communicatively coupled to the photodetector, which is positioned to receive the free space optical energy from the non-splayed ends of the plurality of optical fibers. An optical communication system including the free space optical receiver is also described.

Abstract: A photoacid includes a nucleophilic (NuH) moiety having a photodissociable proton, an electron accepting (EA) moiety, and a bridge structure (X) bonded to both the NuH moiety and EA moiety positioned between the NuH and EA moieties. The NuH and EA moieties each include respective structure so that the EA moiety bonds to a proton photodissociated form of the NuH moiety during a reversible photoinduced intramolecular reaction to form a ring, which has been found to significantly increase the lifetime of the proton dissociation state.

Abstract: A modified optical PAM communication system using multiple laser sources to generate each amplitude level. The systems can be applied separately or in conjunction with another modulation system such as SDM, MDM, WDM, TDM, or other communication systems. In an embodiment, a PAM-4 system will increase data rate by a factor of two, but more complicated schemes using more lasers can be utilized to generate higher efficiency schemes. For example, a 25 Gbps NRZ signal will give 50 Gbps PAM-4 signal and higher laser systems can generate PAM-8 or PAM-16 for 75 and 100 Gbps systems respectively. These can be further applied to SDM systems to generate higher data rates equivalent to the number of SDM channels multiplied by the PAM efficiency. In embodiments, the invention may combing PAM with WDM and SDM to achieve multiple bits per symbol.

Abstract: A multiplexed optical communication system comprising a carrier optical fiber, a plurality of launching light sources, and a matching plurality of multiplexer/demultiplexers and photodetectors is described and claimed. Optical communication channel separation by Spatial Domain Multiplexing (SDM), Optical Angular Momentum (OAM) multiplexing, and Wavelength Division Multiplexing (WDM) is used in combination to achieve significant increase in optical communication channel bandwidth over the prior art. The launching light sources may be positioned such that the light beams are incident on the receiving end of the carrier optical fiber at desired angles including complementary angles. Crosstalk between optical communication channels is minimal. The communication bandwidth of a TDM system may be increased by an order of magnitude due the layered WDM/SDM/OAM data multiplexing of the invention.
