A fiber-optical, wavelength selective switch, especially for channel routing with equalization and blocking applications. The input signals are converted to light beams having predefined polarizations (41). The beams are then laterally expanded (43), and then undergo spatial dispersion in the beam expansion plane. The different wavelength components are directed through a polarization rotation device, pixilated along the wavelength dispersion direction such that each pixel operates on a separate wavelength. Each beam is passed into a pixilated beam steering array (48), for directing each wavelength to a desired output port. The beam steering devices can be MEMS-based or Liquid crystal-based, or an LCOS array. When the appropriate voltage is applied to a pixel and its associated beam steering element, the polarization of the light passing through the pixel is rotated and the beam steered to couple to the selected output port.

The covers stack together in two different ways. First, the covers can be stacked into an “aligned” stack. The aligned stack provides structural rigidity for bulk handling during manufacturing. Second, the covers can be stacked into a “locked” stack. The locked stack provides even more structural rigidity than does the aligned stack and is useful when storing unused covers. The cover includes a first closure portion, an engagement portion, and an alignment portion. The base includes a second closure portion. The first closure portion of the cover is sealingly engageable with the second closure portion of the base to define a sealed storage area. The alignment portion of the cover is engageable with the alignment portion of a second cover to form an aligned cover stack. The engagement portion of the cover is engageable with the engagement portion of a second cover to form a locked cover stack. The cover further includes at least one articulation element circumscribing the engagement portion of the cover and that provides flexibility to the cover allowing the engagement portion of the cover to easily articulate upwardly or downwardly.

A container is disclosed which can include a container base having a cavity therein, a thermal source disposable in the cavity of the base, an insert being insertable within the cavity of the base such that the insert is in close proximity to the thermal source, and a cover. The cover and the insert can define a sealable compartment for the storage of food items. In other embodiments, the cover can be engageable directly with the base to define a storage compartment. The thermal source can act as either or both a heater and a cooler to help maintain the food items stored in the container at a desired temperature.

A dual-channel sunload sensor capable of sensing the intensity and directionality of the solar radiative power entering the cabin of a car through the windshield, for the purpose of providing information to the data processing system of the car that enables a control of the air conditioning system that optimizes the comfort of the driver and of the front passenger. Signals from the sensor offer reliable indications of the solar load power and directionality for a wide range of angular positions of the sun. The sensor includes two convex transparent parts collecting light each toward a respective photodiode, the transparent parts being separated by an opaque portion.

An optical switch having multiple input and output ports directs any number of WDM signals, each arriving at a respective input port, to any one of the output ports. The optical switch includes an array of LC pixels, each positioned to receive a WDM signal transmitted through one of the ports, and an array of reflective elements, each associated with one of the LC pixels. The LC pixels are controlled to cause a WDM signal incident thereon to attain an attenuation state while an output of the WDM signal is being switched by an associated reflective element, such that when an output for a WDM signal is switched from a first port to a second port, the switching can be performed in a hitless manner.

The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

A fiber-optical, wavelength selective switch, especially for channel blocking applications. The input signal is converted to light beams having predefined polarizations relative to the plane in which optical manipulation of the beam is performed. The beams are then preferably laterally expanded in this system plane only, and then spatially dispersed in the beam expansion plane, preferably by means of a diffraction grating. The light is directed through a polarization rotation device, preferably a liquid crystal cell, pixelated along the wavelength dispersive direction such that each pixel operates on a separate wavelength. When the appropriate control voltage is applied to a pixel, the polarization of the light signal passing through that pixel is rotated. The wavelength dispersed beams from all of the pixels are then recombined, and are passed towards a polarization selective device, aligned such that only selected polarization components are transmitted out of the switch.

An audio book comprising: a plurality of leaves with an inductively-powered transponder fastened to each leaf, each transponder having a unique code, one or both of the pages of each leaf bearing printed matter; a power source mounted in the book; an processor connected to the power source and having audio related to the printed matter; and a page sensing circuit including: a reader coil for magnetically inducing an electrical current for powering the transponders; and a receiver connected to the processor for receiving the unique codes from the transponders, wherein the audio related to the matter printed on any one of the pages which is opened is played by the processor according to the unique codes received by the receiver.

A personal air conditioning apparatus includes a centrifugal fan received within a scroll casing. A container mounted to the inlet of the scroll housing is provided for receiving and holding a coolant member. The scroll casing is supported upon a base enclosing two liquid reservoirs and a battery compartment. A liquid atomizing device fed from one of the reservoirs dispenses liquid droplets into air flow from a discharge passage. A channel extends between the container and the other of the reservoirs for draining away condensation formed on the coolant member. The scroll casing defines the discharge passage, which has a cross-sectional area that increases toward an outlet at an end of the scroll casing. Axially opposing faces of the discharge passage are divergent, and the cross section of the discharge passage adjacent the outlet has a shape elongated substantially in the axial direction. The inner end of the container lies above the scroll casing and a surface bounding the lower side of the discharge passage is inclined upwardly from the inlet toward the outlet. The coolant member may be a chilled beverage can and, when the fan is not operating, cooled air drops into the fan where it is retained.
