  • Patent number: 9203757
    Abstract: Embodiments of methods and systems are presented for generating PHY frames with multiple Reed-Solomon encoded blocks in PLC networks. In one embodiment, a MAC layer divides a data frame from a higher level into data blocks. The MAC layer may add a MAC header and/or an error-detection code to each data block. The MAC layer then passes the data blocks to a PHY layer to be individually Reed-Solomon encoded and combined into a single PHY frame for transmission on a PLC network. In other embodiments, the MAC layer passes a single data frame to the PHY layer, which divides the MAC data frame into segments to be individually Reed-Solomon encoded. The individual Reed-Solomon encoded segments are combined into a single PHY frame for transmission on a PLC network.

  • Patent number: 9203472
    Abstract: A system includes an analog front end (AFE) unit to be coupled to a power line network, and a controller coupled to the AFE unit. More specifically, the AFE unit is to receive a packet signal from the power line network wherein, based on a first gain parameter, the AFE unit is to amplify the received packet signal. The controller is configured to calculate a root-mean-square (RMS) power of the amplified packet signal. Further, the AFE unit is to calculate a second gain parameter based on the calculated RMS power of the amplified packet signal and the first gain parameter, wherein the second gain parameter is to be used to amplify the received packet signal instead of the first gain parameter.

  • Patent number: 9202859
    Abstract: An integrated circuit containing a well resistor has STI field oxide and resistor dummy active areas in the well resistor. STI trenches are etched and filled with trench fill dielectric material. The trench fill dielectric material is removed from over the active areas by a CMP process, leaving STI field oxide in the STI trenches. Subsequently, dopants are implanted into a substrate in the well resistor area to form the well resistor. An integrated circuit containing a polysilicon resistor has STI field oxide and resistor dummy active areas in an area for the polysilicon resistor. A layer of polysilicon is formed and planarized by a CMP process. A polysilicon etch mask is formed over the CMP-planarized polysilicon layer to define the polysilicon resistor. A polysilicon etch process removes polysilicon in areas exposed by the polysilicon etch mask, leaving the polysilicon resistor.

  • Patent number: 9204486
    Abstract: A wireless device includes a wireless transceiver configured to transmit to and receive from nodes in a wireless sensor network (WSN) and control logic coupled to the first wireless transceiver. The wireless transceiver transmits a wireless packet to a node in the WSN based on the transmission coinciding with a break in transmissions for a second wireless network. Based on the wireless transceiver being configured to transmit the wireless packets utilizing time synchronized channel hopping, slot frames for packet transmissions in the WSN are time offset so as not to coincide with transmissions made on the second wireless network. Based on the wireless transceiver being configured to transmit the packets utilizing coordinated sampled listening, wake up sequence transmissions for the WSN are time offset so as not to coincide with the transmissions made on the second wireless network.

  • Patent number: 9202583
    Abstract: Read margin measurement circuitry for measuring the read margin of floating-gate programmable non-volatile memory cells. In some embodiments, the read margin of a cell with a floating-gate transistor in a non-conductive state is measured by periodically clocking a counter following initiation of a read cycle; a latch stores the counter contents upon the cell under test making a transition due to leakage of the floating-gate transistor. Logic for testing a group of cells in parallel is disclosed. In some embodiments, the read margin of a cell in which the floating-gate transistor is set to a conductive state is measured by repeatedly reading the cell, with the output developing a voltage corresponding to the duty cycle of the output of the read circuit.
