A system for powering equipment used in a hydraulic fracturing operation, the system including at least one first generator in electrical communication with a first switchgear for providing power to primary components of a hydraulic fracturing operation, and at least one second generator in electrical communication with a second switchgear for providing power to backup components of a hydraulic fracturing operation. The at least one first generator is independent of the at least one second generator so that if the at least one first generator loses the ability to generate electricity, the at least one second generator can continue to generate electricity.

Intrusion Prevention Systems (“IPSs”) are used to detect and / or prevent intrusion events from infiltrating a computer network. However, in large computer networks the IPSs cannot conduct their analysis on network data traffic quickly enough in the network core to meet the demand placed on them by the computer networks, thereby causing delays in the transmission of network data traffic from a source to a destination. To prevent this delay, the IPSs can be configured to intelligently communicate with a high-capacity network switch. The IPSs conduct the initial inspection of the network data traffic flows to determine if an intrusion event is present. However, after the initial inspection, the IPS can inform the switch of what actions to take for future traffic flows including determining which future traffic flows are inspected by the IPSs and which future traffic flows are allowed to be blocked or transmitted to their destination by the switch.

A convertible device that converts between an activity mat and a storage container to capture and store numerous articles. Upon reclosing the activity mat, the articles are recaptured into the storage container. The device includes walls and a base, webbing connected between each adjacent wall pair, and a joint connected between the base and walls so that they are foldable into a third configuration wherein the footprint of the folded device is roughly the size of the base. In the third configuration, the walls are stacked relative to the base. The convertible device may further include two zippers for releasably holding the walls in a rigid and upright position in the first configuration. The webbing can be inwardly biased such that when the walls are urged from the second to the first configuration, the webbing folds toward the interior of the convertible device.

A cellular wireless in-flight entertainment (IFE) system is used in an aircraft for delivering programming to passengers. A head end server provides data and programming to cells. Each cell comprises a wireless access point / configurable antenna to receive the data and the programming. The wireless access point / configurable antenna is disposed at an optimum location in a passenger cabin and operates with a predetermined frequency, radiation pattern, and polarization to provide the programming at optimum coverage. Wireless seat displays receive the programming from the wireless access point / configurable antenna and have a seat display antenna with selectable polarization. The cellular wireless IFE system provides for frequency reuse within the cells, registration of passengers upon log in to identify placement of the wireless seat displays, load balancing to prevent exceeding a capacity of a wireless access point / configurable antenna, and a scalable architecture where data and video each utilize a different band and wireless access point / configurable antenna.

A truck includes an auxiliary power unit having components specifically selected such that they form a stand-alone unit that can fit within an auxiliary compartment of a vehicle and deliver heating, cooling, and additional electric power to the vehicle. Included is an auxiliary engine, an auxiliary alternator, and an auxiliary condenser to provide coolant for a personnel compartment mounted evaporator. An auxiliary voltage regulator provides a ramp-up feature to minimize excessive start-up loads, limits maximum available current from the auxiliary alternator when the auxiliary compressor is engaged, and selectively disables power to electrical components in the event of low vehicle battery voltage. The auxiliary engine includes a radiator system to provide heated fluid for a personnel compartment mounted heat exchanger.

A workload scheduler supporting an efficient distribution and balancing of the workload is proposed. The scheduler maintains (383-386) a profile for each job; the profile (build using statistics of previous executions of the job) defines an estimated usage of different resources of the system by the job. The scheduler tends to select (318-342) the jobs with complementary resource requirements (according to a combination of their attributes); this process can be carried out using either a heuristic approach (318-334) or an optimization approach (335-342). As a result, the jobs that will be submitted are very likely to consume different resources of the system; in this way, any contention for the different resources is strongly reduced.

A high-frequency generator for high-frequency surgery comprises a power generator for supplying high frequency energy at a base frequency. A standardizing factor is determined, with which an output variable from the power generator must be scaled in order to attain a given desired value. Furthermore, harmonics of the base frequency are determined from the output variable and scaled using this factor. By means of an input, the thus obtained signal now controls the output power of the generator. With this arrangement, a reliable first cut may be performed on various kinds of tissue without occurrence of any coagulation.

Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which the QAM modulators that provide data for the individual cables are divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may be transmitted to the nodes using a first fiber, and a second set of IP / on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for this system is also disclosed. The system has high backward compatibility, and can be configured to mimic a conventional cable plant CMTS.

A method of limiting current in a DC motor acts on a full bridge circuit (137) through which the stator winding arrangement (102) of that motor is supplied with current. Upon response of the current limiter, energy supply to the stator winding arrangement (102) from the DC power network is interrupted. The stator winding arrangement is then operated substantially in short circuit via semiconductor switches of the full bridge circuit, and the decaying current flowing in that context serves substantially to continue driving the motor. When that current has reached a lower value, energy supply from the DC power network to the motor is once again activated. The effective value of the current flowing to the motor is preferably reduced when the current limiter responds. The time period during which that current flows, in the form of current blocks, is then increased in compensatory fashion.

A system and method for staggering the starting of embedded system modules of an optical node is disclosed. The embedded system modules of an optical node may be communicatively coupled to a shared data resource required by the embedded system modules during a start / restart. The message traffic associated with the embedded system modules accessing the shared data resource is beneficially distributed by staggering the start process of each of a plurality of embedded system modules over a pre-selected time range.

A refrigerant system includes a controller that enables the system to dehumidify the air in a room without relying on a humidistat and without having to operate the system's compressor and electric heater at the same time. To dehumidify the air, the system's compressor, supply air fan, and outside air damper are controlled in a manner similar to other systems operating in a cooling mode when the room temperature is above a certain setpoint temperature. When the room temperature falls below the setpoint, however, the operation changes significantly. The controller closes the outside air damper, decreases the speed of the fan, and continues operating in this manner until the room temperature decreases to a subcooling temperature limit. The subcooling temperature limit is less than a predetermined limit that is used during the system's normal cooling mode.
