  • Patent number: 9776279
    Abstract: A method and system are provided for crystallizing thin films with a laser system. The method includes obtaining a thin film comprising a substrate and a target layer that contains nano-scale particles and is deposited on the substrate. The heat conduction between the target layer and the substrate of the thin film is determined based on thermal input from the laser system to identify operating parameters for the laser system that cause crystallization of the nano-scale particles of the target layer in an environment at near room temperature with the substrate remaining at a temperature below the temperature of the target layer. The laser system is then operated with the determined operating parameters to generate a laser beam that is transmitted along an optical path to impinge the target layer. The laser beam is pulsed to create a localized rapid heating and cooling of the target layer.

    Abstract: An apparatus includes a device, a comparison circuit, and a switch. The device includes a first terminal coupled to a first power supply signal, and a second terminal coupled to a ground reference. The comparison circuit is configured to compare a first voltage level on the first power supply signal to a second voltage level of a second power supply signal, and enable the device in response to a determination that the first voltage level is greater than the second voltage level. The switch circuit is configured to couple a power supply terminal of the comparison circuit to the first power supply signal in response to determining that the first voltage level is greater than the second voltage level, and to couple the power supply terminal to the second power supply signal in response to determining that the first voltage level is less than the second voltage level.

  • Publication number: 20170109797
    Abstract: A server-side technique to detect and mitigate client-side content filtering, such as ad blocking. In operation, the technique operates on a server-side of a client-server communication path to provide real-time detect the existence of a client filter (e.g., an ad blocker plug-in) through transparent request exchanges, and then to mitigate (defeat) that filter through one or operations designed to modify the HTML response body or otherwise obscure URLs. Preferably, the publisher (the CDN customer) defines one or more criteria of the page resources being served by the overlay (CDN) and that need to be protected against the client-side filtering.

  • Publication number: 20170060952
    Abstract: According to non-limiting embodiments disclosed herein, the functionality of an object cache in a server can be extended to monitor and track web traffic, and in particular to perform rate accounting on selected web traffic. As the server communicates with clients (e.g., receiving HTTP requests and responding to those requests), the server can use its existing object cache storage and existing object cache services to monitor web traffic by recording how often a client makes a particular request in the object cache and/or other data about the requests. Preferably, the object cache is still used for conventional caching of objects, the object cache thus providing a dual role by storing both web objects and rate accounting data.

  • Patent number: 9391523
    Abstract: Methods and apparatuses are disclosed for generating a temperature independent current limit. The value of the temperature independent current limit may be determined based in part on an error signal representative of a difference between an actual output value and a desired output value of a power converter. When the error signal is below a lower threshold voltage, the temperature independent current limit may be set to a first value. When the error signal is above an upper threshold voltage, the temperature independent current limit may be set to a second, higher value. When the error signal is between the lower threshold voltage and the upper threshold voltage, the temperature independent current limit may change linearly with the error signal. The error signal may be adjusted to compensate for changes in the system caused by a change in temperature.

  • Patent number: 9264102
    Abstract: Distortions of both amplitude and phase along a transmission line are compensated for by a trace canceller inserted between a transmitter and a receiver. The trace canceller has an equalizer that compensates for a trace length between the transmitter and the trace canceller. A variable gain amplifier between the equalizer and an output buffer has its gain controlled by an automatic gain control circuit that compares low-frequency swings of the input and output of the trace canceller. The gain of the variable gain amplifier is reduced to prevent the output buffer from saturating and clipping peak voltages on its output. Thus both the variable gain amplifier and the output buffer remain in the linear region. Training pulses from the transmitter are passed through the trace canceller without clipping of peak voltages, allowing the transmitter and receiver to adjust transmission parameters to best match the transmission line.

  • Patent number: 9261550
    Abstract: An in-situ unplug detector circuit detects when a cable is disconnected or unplugged. Detection does not have to wait for normal signaling to pause, such at the end of a frame or timeout. Instead, detection occurs during normal signaling. When the cable is disconnected, the transmitter no longer drives the load at the far end of the cable, and thus can drive the near end to a higher high voltage and to a lower low voltage. The increased voltage swing is detected by a detector at the near end that amplifies the transmitter output to the cable. A fast detector has a higher bandwidth and faster response time than a slow detector, and generates a fast detect signal that crosses over a slow detect signal. When the cable is disconnected, the fast detect signal again crosses over the slow detect signal, and decision logic activates an unplug signal.

  • Publication number: 20150275095
    Abstract: An apparatus and methodology for storing bitumen froth comprising a fluidized bottom, froth first feed holding tank for maintaining effective tank capacity while reducing overall solid bed build up at side walls and minimizing sloughing of solids to the froth discharge outlet. Froth is fed to the tank through one or more feed inlets located between the froth outlet and side walls for fluidizing settling solids. The feed inlets urge solids to settle in sub-beds about the feed inlets, the height of which that manifests adjacent the side walls being less that some design threshold height; if not, then successive feed inlets are located between the side walls and the precious feed inlets to build further sub-beds that have a height at the wall that is less than the threshold height.
