Abstract: An electric utility distribution system in which power is supplied by a distribution transformer through an electric utility meter including an apparatus for detecting the presence of a back-feed voltage source connected to the load. The apparatus includes a virtual neutral established in the electric utility meter at ground potential and a remote switch that is opened to interrupt electric power flow from the distribution transformer to the load. The apparatus further includes a balanced voltage divider circuit including a connection point established between a pair of series connected resistive elements. In addition, the apparatus includes a detection circuit configured to monitor a voltage signal at the connection point to detect a back-feed voltage source connected between a neutral conductor of the electric utility distribution system and one of a first or second power line at the load.

Abstract: Techniques are described herein that are capable of provisioning a trusted execution environment (TEE) based on (e.g., based at least in part on) a chain of trust that includes a platform on which the TEE executes. Any suitable number of TEEs may be provisioned. For instance, a chain of trust may be established from each TEE to the platform on which an operating system that launched the TEE runs. Any two or more TEEs may be launched by operating system(s) running on the same platform or by different operating systems running on respective platforms. Once the chain of trust is established for a TEE, the TEE can be provisioned with information, including but not limited to policies, secret keys, secret data, and/or secret code. Accordingly, the TEE can be customized with the information without other parties, such as a cloud provider, being able to know or manipulate the information.

Abstract: A nock assembly for use with a crossbow bolt includes a nock body defining a notch into which the bowstring of a crossbow is insertable. A light assembly includes a switch member at one end of the notch. First and second spherical caps protrude into the notch and define a first gap therebetween. Third and fourth spherical caps protrude into the notch and define a second gap therebetween. The bowstring is positionable between the spherical caps such that the first and second spherical caps resist movement of the bowstring out of the notch, and the third and fourth spherical caps resist movement of the bowstring toward the switch member. Release of the bowstring from its cocked or drawn position causes the bowstring to pass through the second gap and contact the switch member to turn on the light assembly.

Abstract: Techniques of implementing software filtered non-volatile memory in a computing device are disclosed herein. In one embodiment, a method includes detecting an entry being written to a guest admin submission queue (gASQ) by a memory driver of a virtual machine hosted on the computing device. Upon detecting the entry written to the gASQ by the memory driver, the command in the entry is analyzed to determine whether the command is allowed based on a list of allowed or disallowed commands. In response to determining that the command in the entry is not allowed, without sending the command to the non-volatile memory, generating an execution result of the command in response to the entry being written to the gASQ by the memory driver. As such, potentially harmful commands from the memory driver are prevented from being executed by the non-volatile memory.
