Optical bodies are disclosed that include an optical film and at least one rough strippable skin layer. The at least one rough strippable skin layer can include a continuous phase and a disperse phase. In some embodiments, the at least one rough strippable skin layer can include a first polymer, a second polymer different from the first polymer and an additional material that is substantially immiscible in at least one of the first and second polymers. In some exemplary embodiments, a surface of the at least one rough strippable skin layer adjacent to the optical film comprises a plurality of protrusions and the adjacent surface of the optical film comprises a plurality of asymmetric depressions substantially corresponding to said plurality of protrusions. Methods of making such exemplary optical bodies are also disclosed.

A polarizing film includes a first phase of a first polymer having a birefringence of at least 0.05 and a second phase of a second polymer disposed within the first phase. The index of refraction difference between the first and second phases is greater than about 0.05 along a first axis and is less than about 0.05 along at least one axis orthogonal to the first axis. The diffuse reflectivity of the first and second phases taken together along at least one axis for at least one polarization state of electromagnetic radiation may be at least about 30%. In some exemplary embodiments, the second phase has a refractive index of about 1.53 to about 1.59. In some exemplary embodiments, the second polymer has a glass transition temperature (Tg) higher than the Tg of the birefringent first polymer.
摘要:
An efficient method and system to enhance digital acquisition devices for analog data is presented. The enhancements offered by the method and system are available to the user in local as well as in remote deployments yielding efficiency gains for a large variety of business processes. The quality enhancements of the acquired digital data are achieved efficiently by employing virtual reacquisition. The method of virtual reacquisition renders unnecessary the physical reacquisition of the analog data in case the digital data obtained by the acquisition device are of insufficient quality. The method and system allows multiple users to access the same acquisition device for analog data. In some embodiments, one or more users can virtually reacquire data provided by multiple analog or digital sources. The acquired raw data can be processed by each user according to his personal preferences and/or requirements. The preferred processing settings and attributes are determined interactively in real time as well as non real time, automatically and a combination thereof.

A phased array antenna includes a substrate having a first surface, and a second surface adjacent thereto and defining an edge therebetween. A plurality of dipole antenna elements are on the first surface, and at least a portion of at least one dipole antenna element is on the second surface. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements on the first and second surfaces include respective spaced apart end portions having predetermined shapes and relative positioning for providing increased capacitive coupling between the adjacent dipole antenna elements.
摘要:
A method and apparatus operates an array of laser sources as an integrated array on a single substrate or as integrated in an optical transmitter photonic integrated circuit (TxPIC) maintaining the emission wavelengths of such integrated laser sources at their targeted emission wavelengths or at least to more approximate their desired respective emission wavelengths. Wavelength changing elements may accompany the laser sources to bring about the change in their operational or emission wavelength to be corrected to or toward the desired or target emission wavelength. The wavelength changing elements may be comprise of temperature changing elements, current and voltage changing elements or bandgap changing elements. Identification tags in the form of low frequency tones may be applied relative to respective laser source outputs with a different frequency assigned to each laser source so that each laser can be specifically identified in a feedback control for providing correction signals to the wavelength changing elements to correct for the emission wavelength of respective laser sources.

摘要:
A system and method of conducting a computer-based, simultaneous, multiple round, descending clock auction for basic generation services (BGS) includes receiving bids by an application server host application for processing bids according to auction rules, for tranche units of BGS products, calculating next round prices, and sending round results to bidders, the subsequent round prices and a notice of the number of tranches bid during the previous round and/or the amount of excess supply offered. Subsequently, an electronic withdrawal request to remove tranches from a product and reduce a maximum number bids the bidder can make in future rounds, and/or an electronic switch request to switch a bid to another product, is received. When the number of tranches bid are equal to or less than a certain threshold for each of the products, the auction may end.
