    Abstract: The invention relates to a communication device (8) for wirelessly communicating with a sensor (4). The communication device (8) comprises a receiver for receiving signals, an amplifier for amplifying the received signals, a transmitter for transmitting signals, and a controller. The controller is operable in a first mode in which signal strength values are determined over time, which are indicative of a strength of an amplified received signal, and in a second mode in which signal transmission and reception are controlled based on the determined signal strength values. The determined signal strength values can be indicative of, for instance, a saturation of the amplifier caused by a transmission operation of another, neighboring communication device such that, by considering the determined signal strength values, the transmission carried out by the communication device (8) can be synchronized with the corresponding operation of the neighboring communication device. This can lead to reduced disturbances.

The modulated WDM photonic signal is split one branch sent to a photodetector for generation of an RF outbound signal and transmission of the signal, which is reflected by a target and received as an RF echo signal after a time delay. The other branch has each component wavelength time-adjusted by a second time delay for each wavelength. The resulting time-delayed WDM photonic signal is modulated again based on the received RF echo signal and split into wavelength selective channels. Filters in each channel extract two adjacent photonic signals converted to RF output signals by photodetectors. RF filters select a single RF signal for processing based on the closest difference between the two time delays.

The on-board communication system includes a plurality of interconnected ECUs and a monitoring device including: a determination processing unit to determine whether a message is an authorized message; a discard processing unit to perform processing for discarding an unauthorized message; a storage unit to store the ID of the discarded message; and a notification processing unit to perform processing for outputting, an ACK signal indicating that the reception of the message is complete. The discard processing unit does not discard a message with the same ID as that stored in the storage unit. Each of the ECUs stores the ID added to a message subjected to the discard processing, and prohibits processing of a message with the same ID as that stored in the storage unit.

  • Patent number: 10334096
    Abstract: A vehicle safety function is installed and operative in the vehicle electronics. The vehicle function is implemented via a texting-safety logic inside the vehicle electronics. The texting-safety logic when the vehicle exceeds a threshold speed outputs an RF signal with a texting-safety code. The texting-safety code is picked up by a smart phone in the vehicle to alert the driver about the danger of texting and/or disable the texting feature in the phone while the vehicle is being driven.

  • Patent number: 10325329
    Abstract: A technique allows a smart meter to receive a mask. The smart meter may receive the mask from a utility company or an escrow service. The smart meter may apply the mask to original metered data on a continuous schedule, on a periodic schedule, or on a determined schedule, or on a randomized schedule to conceal the original metered data. The smart meter may apply different masks at different times. The smart meter transmits the concealed metered data as augmented metered data remotely to an electric utility via a communication network.

  • Patent number: 10211899
    Abstract: Systems and methods are described for detecting interference at an access node. A rate at which packets are unsuccessful received at a wireless device may be monitored, wherein the wireless device is in communication with a cell of an access node. The access node may retransmit one or more unsuccessfully received packets to the wireless device. A retransmission metric for retransmission attempts to the wireless device from the access node may be monitored. And it may be determined that communication between the cell of the access node and the wireless device is experiencing interference from a neighboring cell when the monitored rate and monitored retransmission metric meet the interference criteria.
