Abstract: The invention relates to electronic indexing, and more particularly, to the indexing, in a cloud, data held in a cloud. Systems and methods of the invention index data by accessing the data in place in the cloud and breaking a job into work items and sending the work items to multiple cloud processes that can each determine whether to index data associated with the work item or to create a new work item and have a different cloud process index the data. Each cloud process is proximal to an item that it indexes. This gives the system scale as well as an internal load-balancing.

Abstract: A downhole actuator (16) includes a piston (15) within a chamber (17) on which fluid can act on either side to hydraulically activate the actuator. A hydrostatic equilibrium device (18) and a valve (14) are mounted around the hydraulic actuator. With a radial port (28) of the hydrostatic equilibrium device closed and the valve closed to seal the string, pumping fluid through the string operates the actuator. Pressure overbalance prevents movement of the piston (15). The radial port (28) is opened to drain fluid from the string until equilibrium is reached with the annular volume and the piston (15) can be moved.

Abstract: Methods, systems, and computer program products for direct assignment of physical devices to confidential virtual machines (VMs). At a first guest privilege context of a guest partition, a direct assignment of a physical device associated with a host computer system to the guest partition is identified. The guest partition includes the first guest privilege context and a second guest privilege context, which is restricted from accessing memory associated with the first guest privilege context. The guest partition corresponds to a confidential VM, such that a memory region associated with the guest partition is inaccessible to a host operating system. It is determined, based on a policy, that the physical device is allowed to be directly assigned to the guest partition. Communication between the physical device and the second guest privilege context is permitted, such as by exposing the physical device on a virtual bus and/or forwarding an interrupt.

Abstract: Automatic gain control (AGC) may be accomplished in a radio frequency (RF) amplifier in a hybrid fiber-coaxial (HFC) network using a wideband RF tuner to select multiple pilot channels (e.g., frequencies in lower and upper portions of an RF signals spectrum) for use in measuring power and determining a correction to be applied to the RF amplifier. The power of the pilot channel or channels may be measured, for example, using a received signal strength indicator (RSSI) from the wideband RF tuner or using a power detector circuit. Using the wideband RF tuner allows selectable gain and/or tilt control across a wideband spectrum, such as a channel spectrum of a CATV downstream RF signal, to maintain stable RF output levels of the amplifier as RF input levels vary. The RF amplifier may be a line extender amplifier used in a CATV HFC network to amplify a wideband RF spectrum of up to 1.8 GHz.
