Abstract: A device and process for applying a quick dry rapid set aqueous solution. An indicator of a selected color and composition is added to an accelerator to be applied along with a resin. The tinted color indicator is typically blue and allows the user to determine if the proper mixture is being applied. The indicator is visible only during application and disappears after application. The resin and accelerator are applied using an airless spray mechanism with delivery systems and spray gun. The spray gun has 2 nozzles and the capability to set the angle between the nozzles.

Abstract: An external cavity diode laser has been developed to achieve a linear frequency chirp over a broad bandwidth using a silicon photonic filter chip as the external cavity. By appropriately chirping the cavity phase using the gain chip and/or a cavity phase modulator on the silicon photonic chip along with simultaneously varying the filter resonance, approximately linear frequency chirping can be accomplished for at least 50 GHz, although desirable structures with useful lesser chirp bandwidths are also described. With careful control of the chip design, it is possible to achieve predictable behavior of mode jumps along with large scannable ranges within a mode, which allows for stitching together segments of linear chirp through a mode jump to provide for very large chirp bandwidths greater than 1 THz.

Abstract: A method and apparatus for delivering a message to a caller prior to the moment the recipient unhooks or answers their telephone or other network interface device, as well as optionally delivering a message to the caller, the recipient, or both after the connection between the service provider and the caller, and/or the connection between the service provider and the recipient has been established. The method and apparatus are effective for use with all telecommunications systems, including, but not limited to, optical-based telephone systems, wire-based telephone systems, wireless telephone systems, optical-based computer network systems, wire-based computer network systems, wireless computer network systems, and heterogeneous network systems.

Abstract: A computerized method, program product, and a service that resolves the business problem by enabling an automated and simplified process to generate DDL and JAVA classes directly from a MOF definition. The method, program product, and service creates useful computing artifacts from a set of abstract and generic specifications described in the MOF format. The computing artifacts include a DDL database schema having tables that accurately reflect the object-oriented hierarchy of the objects described in the MOF format; JAVA classes that correspond to the objects defined in the MOF format; object-to-relational (O/R) mapping file that maps the JAVA classes and their attributes to the tables and columns in the DDL database schema; SQL insert statements for loading the data of enumerated list values into the tables and the JAVA classes; database design reports; and O/R name translation reference reports.

Abstract: The techniques described employ a cooperative organization of network service providers to provide improved distributed network services. The network service providers that are constituent to the cooperative organization represent various perspectives within the overall Internet content distribution network, and may include network owners, telecommunications carriers, network access providers, hosting providers and distribution network owners, the latter being an entity that caches content at a plurality of locations distributed on the network. Aspects include managing content caches by receiving control signals specifying actions related to cached content that is distributed on a network, such as the Internet, and forwarding the control signals through to the caching locations to implement the actions represented by the control signals, thus providing content publishers the capability of refreshing their content regardless of where it is cached.

Abstract: In one embodiment of the present invention, an apparatus operates a control loop for a tunable optical device. A digital reference signal is converted to an analog reference signal and then introduced into the optical path of the tunable optical device. An analog feedback signal, corresponding to the digital reference signal, is recovered from the tunable optical device. The analog feedback signal is converted to a digital feedback signal. The apparatus sends tuning information to the tunable optical device based on analysis of the digital reference signal and the digital feedback signal. In one embodiment, the tuning information is used for wavelength locking of the tunable optical device. In another embodiment, the operation of the control loop is synchronized with another function of the tunable optical device.

Abstract: Tunable laser systems use servo control loops to control and monitor laser parameters such as channel, temperature, and power. The many control loops operate asynchronously, which means that noise generated by input sampling and/or output updating from one or more loops could interfere with the sampled inputs of one or more of the other loops. Embodiments of the present invention synchronize setting and sampling of tunable laser parameters to reduce noise. Noise that is related to synchronized setting and sampling of tunable laser parameters allows the noise to be reduced to constant offsets to be compensated for in the laser parameters of interest.

Abstract: A tunable optical unit includes a resistive temperature device (RTD), a thermal tuning device and a measurement circuit. The RTD has a resistance dependent on a temperature of the thermal tuning device. The measurement circuit outputs a signal that is dependent on the resistance of the RTD. The signal is used to control the temperature of the thermal tuning device in tuning the tunable optical unit. A reference resistance can be connected in series with the RTD to make ratio-metric measurements to determine the RTD's resistance (and hence the temperature of the tuning elements) without having to know the value of the current conducted through the RTD and to reduce sensitivity to fluctuations in the excitation signal.
