A trusted container management system provides process supervision, such as for software or other executable processes. In an embodiment, a particular edge controller can include a Rich Execution Environment (REE) and a Trusted Execution Environment (TEE). In an example, an application executes in a container of the REE and generates communication data and a signature identifier. A DeftT publication is generated and includes the communication data. An untrusted validator in the REE evaluates the DeftT publication according to a trust rule associated with the communication data and publishes the DeftT publication. A secure validator executing in a Trusted Execution Environment (TEE) further evaluates the DeftT publication. The further evaluation can include subscribing to the certificate identified by the signature identifier, determining the public key and the role of the certificate, and validating the DeftT publication based on the public key. The further evaluation can further include subscribing to a particular trust rule.

Trusted software container management system

Secure communication between users and resources of an electrical infrastructure and associated systems and methods. A representative secure distributed energy resource (DER) communication system provides for the creation of trust rules that govern the permitted communications between users and resources of an electrical infrastructure system, and the enforcement of the trust rules.

Configurable network security for networked energy resources, and associated systems and methods

A solar monitor measures electrical characteristics of a designated solar device within an array of solar devices that are coupled in series. The solar monitor includes a charge storage element and a charger coupled to the charge storage element to establish a positive voltage and/or a negative voltage on the charge storage element. A switch within the solar monitor is coupled in a shunt configuration with the designated solar device and with a subsequent device in the array. The switch selectively couples the charge storage element to the designated solar device to vary an operating current that flows between the designated solar device and the subsequent solar device. The solar monitor includes a current detector to measure the current of the designated solar device, and a voltage detector to measure the voltage of the designated solar device.

Multiple signals are graphically presented. A signal for each measured frequency channel is separately represented on a display. Representations of the signals are superimposed. Center channel frequencies for all the representations of the signals are aligned relative to a single position on a first axis. Amplitude for all the representations of the signals is indicated relative to a second axis. Overlap of a signal within a compliance mask indicates violation of an amplitude minimum, an amplitude maximum or frequency drift.

Graphical presentation of spectral information for aid in compliance measurements

A nonpolarization-dependent method and apparatus for optical sampling of a user optical signal of a known frequency range (e.g., corresponding to 1550 nm wavelength) uses a probe signal in an unsplit form and applies a conversion {e.g., by sum frequency generation (SFG)} operation in a first stage to the probe signal and to a first polarization component of the user optical signal (e.g., 's' component) to produce a first component of an output signal. In a second stage, a second polarization component of the user optical signal (e.g., 'p' component) is rotated by 90&#xb0; to align with the first polarization component and then converted by mixing with the unsplit probe signal to produce a second component of an output signal. The first and second output component signals are both added and measured using a photomultiplier tube (PMT) or an avalanche diode.

Polarization-independent optical sampling with extended wavelength range

A sampling apparatus for use in high data rate jitter measurement systems based on offset sampling uses a trigger circuit, along with a time-based variable delay, to align a sampling strobe to drive two samplers. An input data signal is split and fed via separate signal paths into the two samplers. One of the samplers is delayed in sampling the input signal or the input is delayed to one of the samplers, such that the two samples of the input signal are offset in time. The jitter present in the SUT can be calculated using the two samples. In addition, when using two strobe circuits, the jitter inherently present in the strobe circuits can be compensated for by offset sampling a reference clock with each main strobe to determine the phase and cycle number of the reference clock at each strobe time.

Zero-crossing direction and time interval jitter measurement apparatus using offset sampling

A method and apparatus for sampling optical input signal is presented. The apparatus includes a split waveplate for spatially rotating polarization direction of a first portion (for example half, or 50 percent) of the input signal to a first rotated direction and spatially rotating polarization direction of a second portion (for example the other 50 percent) of the input signal to a second rotated direction orthogonal to the first rotated direction. The apparatus further includes a sum frequency generator, for example a PPLN crystal, aligned to the first rotated direction to sample the input signal. The rotation of the two halves of the input signal is achieved using a split half-waveplate.

Simplified polarization independent optical sampling using a spatially split waveplate

Repetitive sampling of a data signal is performed. A clock reference is generated. The clock reference has a known period relationship with the data signal. The clock reference and the data signal are simultaneously sampled. The sampled information from the clock reference is used to determine in what phase of the clock reference sampled values of the data signal occur.
