To greatly simplify the developer's task, an application function server or application logic controller (“ALC”) server runs on a digital electronic device with a common set of tools and methods to deliver high-value capabilities to applications developed in different application languages and running in various different application environments. The applications and the application function server have a local client-server relationship. The functions themselves are provided by various plug-ins. The interface of a plug-in illustratively is a discrete set of functions, common to the command plug-ins. The ALC Server accepts simplified commands directly from the applications, applies the appropriate policy, and interacts with the plug-ins to perform the requested functions on behalf of the applications. The result is that applications can use various capabilities without dealing with the complex methods, standards, and system interoperability required to make the technologies work, and technology additions and upgrades can be performed independently from the applications that use them.

A new broadband source having a discrete set of spectral emission lines having high peak power in each line is provided by placing a gain medium in a reflective cavity comprising reflective front and back surfaces. A cavity feedback factor less than unity is achieved by providing reflectivity of one surface substantially lower than the reflectivity of the other surface such that spontaneous emission in the gain medium is linearly amplified just below the lasing threshold. In an alternative arrangement, a movable external back surface placed at a prescribed distance from the gain medium provides a means to achieve a free spectral range and finesse of the emission lines to match a pitch of a detector array in a SD-OCT system. By simultaneously providing high power to each detector element of the array, sensitivity and imaging speed of SD-OCT system are significantly improved.

An optical system comprising two or more optical switches co-packaged together comprising discrete sets of input fiber ports (N per set) and an output fiber port (1 per set), and wherein λn from said set of multiple input fiber ports (N) is focused on λn mirror via the use of shared free space optics, one or more discrete arrays of micro electromechanical system (MEMS) mirrors in a shared array, wherein at least a first array of MEMS mirrors is utilized to select and switch selected wavelengths from the first set of input fiber ports to an output fiber port of the same set, and wherein at least a second array of MEMS mirrors using and sharing the same free space optics as the first MEMS array is utilized to produce another fiber optic switch, thus, enabling one or more N×1, or alternatively one or more 1×N co-packaged optical switching system.

A high port count instantiated wavelength selective switch comprising two or more discrete sets, or instances, of m fiber ports totaling N fiber ports co-packaged together, one or more shared optical elements and dispersive elements, and one or more steering elements in each instance. The steering elements steer λ_(k) from each instance of m input fiber ports to a λ_(k) mirror dedicated to that fiber port instance, and wherein λ_(k) mirror of the instance of m fiber ports is utilized to select and switch one λ_(k) from the instance of m fiber ports to a fixed mirror which in turn reflects λ_(k) to the λ_(k) output mirror. The λ_(k) output mirror selects and switches one λ_(k) from one of the one or more instances of m fiber ports of the N×1 optical switch to the 1 output fiber port for each wavelength, and vice-versa for the 1×N optical switch.

A spectrum analyzer for the simultaneous analysis of electromagnetic radiation delivered to it from either multiple sources or from a linear segment along a source surface, and arranged as either continuous or discrete set of points along a short piece of a straight line referred to herein as a slit. In one embodiment of the invention, the optical design of the dispersing part of the analyzer provides essentially stigmatic spots for any spectral band up to one octave wide in the spectral range of about 400 nm to about 2500 nm.

Emitter target range and heading are estimated from bearing measurements enhancing bearings-only estimator convergence to a target track, and permitting optimization of an observer position relative to the target at the end of the total bearing measurement period. One or more estimates of the target range, speed and heading made from bearing measurements before an observer maneuver are used to determine the most appropriate observer maneuver giving complete bearings-only target-motion-analysis observability. A set of parameters characterizing a set of potential emitter signal sources is generated based on measured emitter characteristics. A most probable set of emitter platforms is identified and the emitter operating mode and corresponding platform set are associated with a kinematic regime set. A specific speed or discrete set of speeds best adapted to a set of all possible platform missions, emitter speed as a continuous function of emitter range, and emitter range are all determined.

The invention relates to an FPGA (mixed random space voltage vector pulse width modulation method) and a modulator based on a field programmable gate array. According to the method, action time and pulse and pulse positioning of a basic voltage sector are controlled by two random variables, one of the two random variables is used for controlling the action time of the basic voltage vector by controlling distribution proportion of action time of two zero vectors, and the other random variable is used for performing pulse positioning by controlling the position of the widest high-level pulse. The modulator comprises a period register, a dead zone register, two groups of hop time registers, a counting and initial value reloading circuit, a register switching circuit and a pulse generation circuit, and an asymmetrical control pulse is generated through alternative comparison of the two groups of hop time registers. By the modulation method and the modulator, mechanical vibration, audio-frequency noise, electromagnetic radiation and the like due to a large peak value of a discrete set cluster spectrum are obviously avoided on the premise that fundamental wave voltage and switching frequency do not change.

In the invention, an electrochemical etching of crystalline germanium or a germanium alloy produces well-segregated chromatic clusters of nanoparticles. Distinct strong bands appear in the photoluminescence spectra under 350 nm excitation with the lowest peaks in wavelength identified to be at 430, 480, and 580 and 680-1100 nm. The material may be dispersed into a discrete set of luminescent nanoparticles of 1-3 nm in diameter, which may be prepared into colloids and reconstituted into films, crystals, etc.

A method, system, and computer-readable storage medium are disclosed for partitioning a scene with discrete oriented planes. In one embodiment, a scene comprising a plurality of objects may be partitioned into a plurality of sub-regions. The sub-regions may be divided by a plurality of planes having orientations selected from a discrete set of orientations comprising at least one orientation that is not the x axis, y axis, or z axis and is at a nonzero angle with respect to the x, y, or z axes. The partitioned scene may be stored in a binary tree comprising a plurality of nodes. Each node may correspond to a sub-region. In one embodiment, a ray tracing query may be solved for a particular ray. In solving the ray tracing query, the tree may be traversed to identify a first object of the plurality of objects intersected by the ray.

A method for differentiating or promoting or inducing differentiation of stem cells into pluripotent cardiovascular progenitors (MCPs) by transiently inducing the expression of a single gene, namely Mesp1, is disclosed. Cells obtained by the method and their uses in research and clinical settings are also disclosed. Using genome wide transcriptional analysis, the inventors found that Mesp1 rapidly activates and represses a discrete set of genes, which form potential new targets for both therapy and for the identification of MCPs. Insights into the molecular mechanisms underlying the earliest step of cardiovascular specification and potential methods for dramatically increasing the number of cardiovascular cells for cellular therapy in humans are provided.
