An expandable apparatus for use in a borehole includes a tubular body having at least one opening extending between a longitudinal bore of the tubular body and an outer surface of the tubular body and at least one member positioned within the at least one opening of the tubular body. The member is configured to move between a retracted position and an extended position. An actuation structure is positioned within the tubular body. The actuation structure is coupled to the at least one member and is configured to move the at least one member from the retracted position to the extended position responsive to a flow rate of drilling fluid passing through the longitudinal bore.

A network-equipment-implemented method and apparatus for tracking durations of flows received at a network node in consecutive intervals utilizes two counting bloom filters in ping-pong operation to reduce memory and processing. Identifiers for flows that exceed a predetermined duration or number of intervals are stored in a long-duration flow-identifier table. Hash functions used within the counting bloom filters and optionally used in the long-duration flow-identifier table are chosen to minimize the probability of false positives in the detection of long-duration flows. In some embodiments, flows are sampled to conserve memory and processing resources at the risk of missing detection of some long-duration flows.

摘要:
This invention discloses a type of stepper motor driver integrated circuit, comprising of a control logic circuit module and a connected stepper motor driver circuit module. The outputs, in groups of two, of the stepper motor driver circuit module are connected to the two ends of coil windings in the stepper motor. Its characteristic is that it is equipped with an I2C serial bus connection which allows the main controller of I2C bus to directly connect to the control logic circuit module via the SDA, SCL, and GND lines resulting in duplex data transmission. With fewer number of signal ports, more driver integrated circuits can also be connected to the same I2C bus. Each driver integrated circuit can directly drive a stepper motor and it can also drive different numbers of stepper motors using different channels. In particular, the multi-channel stepper motor driver integrated circuit has fewer input contact points and thus it clearly reduces the chip area as well as the manufacturing cost which allows the chip to be used in a wide range of digital equipment and electronic information products where space is limited such as with cellular phone photo modules.

A computer-implemented method, apparatus, and virtual machine for facilitating the communication between VMs. The method of facilitating the communication between a first VM and a second VM includes: allocating a shared memory segment from within the memory of the physical machine; mapping the requested memory space addresses to the shared memory segments in response to the memory space requests from the VMs; and providing the requested memory space addresses. A method of communication from a first VM to a second VM includes: requesting a memory space in response to a notification that a shared memory segment has been allocated; obtaining the requested memory space address, which has been mapped to the allocated shared memory segment; and accessing communication data in the shared memory segment according to the address. The apparatus and virtual machine executes the steps of the methods.
摘要:
Systems and techniques for performing power conversion operations in a portable device are used to convert an input voltage to a voltage at an output. The conversion operations use a two-stage conversion to convert the input voltage to a first voltage and to convert the first voltage to a second voltage. A switching frequency is altered with changes in the input voltage. The switching frequency is selected based on the input voltage level and/or to maintain a substantially consistent ripple at the output, which can correspond to the first voltage and/or the second voltage.
