CATV equipment fast boot after power interruption
Recovering a hardware component, such as a Remote MACPHY node (RMN), a wireless base station, a CATV amplifier, a Wi-Fi hotspot, a microcell, or a PON switch, after a power interruption. A hardware component, upon detecting that input power to the R-PHY device will be imminently interrupted, provides an alarm signal to a central processing unit (CPU) in the R-PHY device. The CPU, in response to receiving the alarm, stores running parameter data for the R-PHY device in a non-volatile memory. The running parameter data is normally obtained through network communications during a boot operation of the R-PHY device. If certain conditions are satisfied, then the R-PHY device recovers from the interruption in input power using the stored running parameter data without obtaining the running parameter data through a normal boot operation, thus shortening the boot time. |

A message is embedded within an entropy stream. The message is encrypted using a onetime pad (OTP) and thus looks like part of the entropy string since the OTP encrypted messages is, as long as the “pad” material and message content are known, itself random to the observer.

For example, the OTP-encrypted message may indicate the number of units of the message, and point to a position in another part of the stream where another message is located. The stream may be randomly and deterministically expanded. Other techniques encrypt a stream using standard encryption, the stream comprising messages that are deterministically OTP encrypted; expand said encryption using a byte vector/array of randomness including at least one random vector; periodically swap out at least one member from the vector; hide vector random bytes in messages and/or using the messages to direct which bytes to remove from the stream of randomness/entropy; and store a stash of randomness separately from the messages and/or pull off the random/entropy stream as directed by the messages.

Sensor, corresponding system and operating method
An energy-harvesting generator provides energy for storage in a capacitor. A sensing circuit senses a voltage across the capacitor and generates an activation signal as a function of the sensed voltage.

A signal transmitter powered by stored energy in the capacitor responds to the activation signal being switched to the second value by activating and transmitting a transmission signal. The signal transmitter further responds to the activation signal being switched to the first value by discontinuing transmission of the transmission signal and deactivating. A duration of time elapsing between de-activation and activation of the transmitter is indicative of an amount of energy harvested by the energy-harvesting electric generator. |

On-chip power supply noise suppression through hyperabrupt junction varactors
The increasing power density and, therefore, current consumption of high performance integrated circuits (ICs) results in increased challenges in the design of a reliable and efficient on-chip power delivery network. In particular, meeting the stringent on-chip impedance of the IC requires circuit and system techniques to mitigate high frequency noise that results due to resonance between the package inductance and the onchip capacitance. In this paper, a novel circuit technique is proposed to suppress high frequency noise through the use of a hyperabrupt junction tuning varactor diode as a decoupling capacitor for noise critical functional blocks. With the proposed circuit technique, the voltage droops and overshoots on the onchip power distribution network are suppressed by up to 60% as compared to MIM or deep trench decoupling capacitors of the same capacitance. In addition, there is no added latency to react to power supply noise and there is no degradation to circuit performance as compared to existing techniques in commercial products and literature. |
