Abstract: A wavelength selective switch architecture for ROADMs for switching the spectral channels of a multi-channel, multi-wavelength optical signal between input and output ports employs a biaxial MEMS port mirror array for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander for expanding input optical signals to create an elongated beam profile, a diffraction grating for spatially separating the spectral channels, an anamorphic focusing lens system, an array of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The bi-axial channel micromirrors are rotatable about one axis to switch spectral channels between ports, and are rotatable about an orthogonal axis to vary the coupling of the spectral channel to an output port and control attenuation of the spectral signal for complete blocking or for a predetermined power level.

Abstract: A painter's accessory holder is disclosed for holding painting accessories, such as a caulking gun, sandpaper, glazing compound and a bladed tool on a base member that is attachable to a belt worn by the painter. The accessory holder includes a caulking gun bracket attached to the base member configured to accept a caulking gun, the caulking gun finger guard engaging a portion of the bracket to securely hold the caulking gun in place, while at the same time rendering it easily removable. A sandpaper bracket is attached to the base member to clamp sandpaper between the bracket and the base so as to be securely but removeably held and readily accessible to the painter. The device also may include a pouch attached to the base member to hold a glazing compound and a bladed tool bracket to hold bladed tools, such as putty knives, etc.

Abstract: A toy water gun that can release a directed stream of water from a pressurized receptacle is disclosed. The toy water gun is connected to the pressurized receptacle by a flexible hose and a pull on the trigger releases a directed stream of water. In one embodiment, the receptacle has a one way valve attached thereto that allows pressurized water to only enter the receptacle. A flexible tube is attached to the one-way valve on one end with the flexible tubing terminating with a hose fitting on the other end attachable to a hose bib. The pressurized water is supplied by a water system such as a municipal water supply. Another embodiment uses a bladder inside a receptacle containing trapped air that is connected directly by flexible tubing to a shut off valve which is further connected by flexible tubing to a hose bib that supplies pressurized water.
