摘要： The service phase of the electrical connection to a customer endpoint device located within a power distribution system is determined by various techniques. At the feeder level, the system may be programmed to induce momentary power interruptions, thereby causing missed zero crossings at the customer endpoint devices. The pattern of these interruptions is a controlled one, designed specifically to avoid causing noticeable disruption even to sensitive devices, but to be unusual enough that it is statistically unlikely to be naturally occurring. The monitoring of the zero crossing information is used to determine the phase of the service line to the customer endpoint devices.

摘要： Methods, systems, and devices for detecting when an end-device is physically disconnected from a commodity delivery network. One method includes determining an impedance of a power input of the end-device after the end-device experiences a power interruption, generating a message including data regarding the impedance, transmitting the message to a computer-implemented back office over at least one communication network, and automatically setting a status of the end-device to a physically-disconnected status when the data regarding the impedance indicates the impedance is greater than a threshold.

摘要： A system that provides a cryptographic unit that generates secret keys that are not directly accessible to software executed by a controller. The cryptographic unit can include a restrictor device, a finite state machine, a random number generator communicatively and a memory. The memory stores values generated by the random number generator. The restrictor device and the finite state machine include hardware logic that restricts access or changes to the contents of the memory.

摘要： Devices and methods for securely upgrading devices, such as field upgradeable units, are disclosed. In response to receiving an update object, a device may determine whether a predefined location of memory includes a predetermined value. Based on the value in the predefined location, the device may store the received update object in a verification portion of the memory. After verifying the authenticity of the update object, the device may copy the update object from the verification portion of the memory to an inactive portion. The inactive portion of the memory can be swapped with an active portion of the memory, such that the inactive portion becomes active.
