Abstract: Technologies for untrusted code execution include a computing device having a processor with sandbox support. The computing device executes code included in a native domain in a non-privileged, native processor mode. The computing device may invoke a sandbox jump processor instruction during execution of the code in the native domain to enter a sandbox domain.

While executing in the sandbox processor mode, the processor denies access to memory outside of the sandbox domain and may deny execution of one or more prohibited instructions. From the sandbox domain, the computing device may execute a sandbox exit instruction to exit the sandbox domain and resume execution in the native domain. The computing device may execute processor instructions to configure the sandbox domain. Other embodiments are described and claimed.

The insulating member includes an insulating body having a through hole penetrating therethrough, and a peripheral wall protruding from the insulating body and surrounding an opening of the through hole. The movable contact has a fixed portion fixed in the insulating body, and an exposed portion exposed from the insulating body. The fixed portion of the movable contact is surrounded by the insulating body so that the movable contact is electrically isolated from a drive shaft passing through the through hole. The peripheral wall of the insulating member increases a creepage distance between the drive shaft passing through the through hole and the exposed portion of the movable contact.

Abstract: In an indoor environment on fire, automatic deployment of sensors disposed on, beneath or over the floor to look upward the ceiling to observe a body of smoke and flame risen near the ceiling allows important information regarding states and dynamics of the body of smoke and flame to be gathered at an early stage of fire (e.g. before arrival of firefighters). By distributing the sensors over the indoor environment, the states and dynamics of the body of smoke and flame are monitored holistically (i.e. as a whole) even at the early stage of fire. Such information is useful to predict development of the fire. In one implementation, a sensor is held in an infrastructure sensor holder mounted on the ceiling during normal time. Upon detecting occurrence of fire, the sensor drops from the holder to land on the floor and orients a sensing direction vertically upward to perform monitoring.
