Abstract: Novel subsea excavation apparatus and methods that exert force between a subsea anchor point and an excavator using a subsea actuator. In some examples the subsea actuator is attached to an anchor point on the seabed and the excavator directly. In other examples, a guide frame is anchored to the seabed to provide anchor points fixed relative to the seabed and the subsea actuators are attached to the guide frame and the excavator. In further examples, the subsea actuators can be attached to the excavator through a carrier frame or other excavator guides rather than directly to the excavator.

Abstract: Machines and methods are described for displaying a particular symbol at a corresponding symbol position for multiple consecutive outcome events, such as outcome events including a wager game played on a stand-alone machine located within a casino or a machine within a client-server architecture. After displaying the particular symbol for a first outcome event, the particular symbol can be displayed at the same symbol position within a symbol-display-portion for one or more successive outcome events without the particular symbol being selected to be displayed at the same symbol position. Other symbols displayed within the symbol-display-portion for the first and successive outcome events can be determined or selected by a processor using a random selection process. The particular symbol can be a Wild symbol. A data structure can include data for tracking whether the particular symbol is locked down for an outcome event after the first outcome event.

Abstract: An example method includes determining, for a first outcome event, a first symbol set to display within a symbol-display-portion of a display of the machine; displaying, by the display for the first outcome event, the first symbol set; determining, by the machine for a second outcome event occurring after the first outcome event, a second symbol set to display within the symbol-display-portion of the display; determining, by the machine for the second outcome event, for each instance of the particular symbol in the first symbol set, a corresponding second symbol position in the symbol-display-portion of the display; and displaying, by the display for the second outcome event, each instance of the particular symbol in the first symbol set randomly selected for the first outcome event at the corresponding second symbol position and each symbol of the second symbol set within the symbol-display-portion of the display.

Abstract: Machines and methods are described for displaying a predetermined symbol and a set of symbols selected from a global symbol set. A first symbol position can be randomly selected for displaying the predetermined symbol, which can include a multiplier meter to display a multiplier value randomly selectable from multiple multiplier values. A second symbol position can be randomly selected for displaying the predetermined symbol after moving along a path from the first symbol position. The predetermined symbol can be displayed as part of a predetermined number of outcome events earned upon determination that a trigger event occurred. A server machine can select symbol positions, multiplier values and symbol sets and provide data indicating the symbol positions, multiplier values and symbol sets to a client machine. The client machine can include a display to display the symbol sets, and multiplier values within a predetermined symbol.

The system may also include means for pre-tensioning the micropiles after deployment, where the controller is programmed and configured to determine whether the pre-tensioning process conforms to design criteria.

Abstract: Systems, methods, routines and/or techniques are described to protect users from undesirable content, for example, on an open platform. One or more embodiments may prevent the installation of an application package or warn a user if the application package may be undesirable (e.g., because it may contain malware). In one or more embodiments, a method may include receiving a first request to install an application package, and receiving and/or capturing metadata related to the application package. The method may include communicating a second request (e.g., including the metadata) to a remote server, such that the remote server can determine whether the application package may be undesirable. The method may include receiving a response from the remote server, where the response may indicate whether the application package may be undesirable, and initiating installation of the application package if the application package is determined to be safe and/or acceptable.

Abstract: An application distribution server may be operable to perform an application distribution process for an application, where the application distribution process may comprise a plurality of phases. The plurality of phases may comprise, in sequence, a developer account creation phase, a risk assessment phase, an application upload phase, an application publication phase, an application promotion phase and an application download phase. The application distribution server may detect, at each of the plurality of phases, whether a particular behavior corresponding to use of the application to distribute undesirable software may occur. In instances when an occurrence of the particular behavior is detected at a certain phase in the application distribution process, the application distribution server may continue, utilizing a trap system, one or more subsequent phases after the certain phase for the application, without communicating information on the detection of the occurrence of the particular behavior.

Abstract: High frequency power amplification modules comprise a dielectric substrate supporting a stepped impedance transition coupled to the input of a power amplifier and a symmetrically disposed stepped impedance transition connected to the output of the power amplifier. The power amplification modules are oriented in an electromagnetic energy field so that input electromagnetic energy is coupled to the input of the power amplifier by the input side stepped impedance transition, amplified by the amplifier, and emitted from the module by the output side stepped impedance transition. A plurality of the power amplification modules may be organized into an array to provide a power combiner. The power amplification modules in the array may be linked by isolation impedances that decouple the modules in the array.

Abstract: An n-stage RF choke comprises a series connection of two or more inductors connected in series between a source and a load. The inductor closest to the source has the largest inductance and the inductance closest to the load has the smallest inductance. The inductances of any inductors between the inductor closest to the supply and the inductor closest to the load decrease as a function of distance from the supply. The junctions between the inductors in the series connection are shunted to ground by capacitors connected in series with resistors that provide a matched termination for increasing bandwidth by lowering circuit Q factors and eliminating resonant frequencies. The capacitor closest to the supply has the largest capacitance and the capacitor closest to the load has the smallest capacitance. Any intermediate capacitors decrease in capacitance as a function of distance from the supply. Such an arrangement provides a high impedance that isolates the load from the supply at a wide range of frequencies.
