Abstract: A system for improving communication between surface and downhole equipment, in some embodiments, comprises: a first transceiver in a formation; a second transceiver in the formation; and a third transceiver in the formation, the second transceiver positioned between the first and third transceivers, wherein, upon determining that a communication quality metric pertaining to wireless communication in the formation fails to meet a criterion, the first transceiver transmits data to the second transceiver, wherein, upon determining that said communication quality metric meets the criterion, the first transceiver transmits said data to the third transceiver in lieu of transmitting said data to the second transceiver.

Abstract: Techniques are described for managing communications for a managed computer network by using a defined pool of alternative computing nodes of the managed computer network that are configured to operate as intermediate destinations to handle at least some communications that are sent by and/or directed to one or more other computing nodes of the managed computer network. For example, a manager module associated with a source computing node may select a particular alternative intermediate destination computing node from a defined pool to use for one or more particular communications from the source computing node to an indicated final destination, such as based on a configured logical network topology for the managed computer network and/or on one or more other selection criteria (e.g., to enable load balancing between the alternative computing nodes). The manager module then forwards those communications to the selected intermediate destination computing node for further handling.

Abstract: A power storage device includes a storage battery, a mounting unit that detachably mounts the power storage device on a motor-driven moving object, an output controller that controls output of driving power from the storage battery to the motor-driven moving object, and a controller that, when the motor-driven moving object is within a particular area, causes the output controller to reduce the driving power supplied from the power storage device to the motor-driven moving object compared to the driving power when the motor-driven moving object is outside the particular area.

Abstract: In an example, a serial peripheral interface (SPI) flash memory controller includes a transmit first-in-first-out (FIFO) circuit and an SPI interface operable to provide an interface between the transmit FIFO and an SPI flash memory. The SPI flash memory controller further includes a random access memory (RAM) operable to store a memory interface file, an address interface of the RAM operable to receive a command from the transmit FIFO circuit, a data interface of the RAM operable to output a control word associated with the command. The SPI flash memory controller further includes state machine logic operable to set behavior of the SPI interface based on the control word output from the RAM, where the control word includes a data direction field, a data phase field, an addressing width field, an addressing phase field, and a command error field.

Abstract: Radio Frequency (RF) transmitter adaptors, methods and articles of manufacture are disclosed. A method of adapting an RF transmitter for using in controlling a radio controlled (R/C) device having an RF receiver includes receiving a pulse-position modulation (PPM) signal from the RF transmitter, automatically selecting a channel assignment map based on the PPM signal, and generating, from the PPM signal, an RF communication signal compatible with the RF receiver for use in controlling the R/C device based on the selected channel assignment map.

Abstract: A receiver in an impulse wireless communication. The receiver (300) includes a pulse-pair correlator (304) that receives a signal (316) and divides it into two signals for paths. One of the signals is input to signal multiplier (312) while another signal is delayed by a delay unit (310). The signal multiplier (312) multiplies the received signal (316) by a delayed signal (318). An integrator (314) integrates an output signal (322) over a designated period of time. An adding module (306) sums an output signal (324) from the integrator (314). An acquiring module (308) compares an summing-up output (326) from the adding module (306) with a predetermined threshold value to detect the existence of a transmitting-standard preamble.
