Abstract: A wireless load control system for controlling one or more electrical loads comprises a wireless control device (e.g., a gateway device) able to obtain a present time from a server via a network (e.g., the Internet), control the electrical loads according to a timeclock schedule, and disable the timeclock schedule if the present time is not able to be obtained from the server via the network. The wireless control device may also be able to obtain the present time from a digital message received from an external device (e.g., a smart phone or a tablet device) via the network. The wireless control device may be configured to receive a control signal indicating a power outage (e.g., from a battery backup device), and to operate in a low-power mode in response to receiving the control signal indicating the power outage.

Abstract: Apparatus includes an ignition system that repeats an ignition cycle by providing hydrogen and oxygen and also provides a control spark with a sufficient amount of energy for igniting a combustible mixture of hydrogen and oxygen. The combustion chamber is immersed in an aqueous fluid, fills with the same or other aqueous fluid, receives the hydrogen and oxygen therein, receive the control spark to ignite the combustible mixture of hydrogen and oxygen to cause a combustion reaction to occur and form steam that yields a specific amount of heat energy, and provides the aqueous fluid from the combustion chamber in response to the substantial increase in pressure on the aqueous fluid contained therein.

Abstract: Surface relief holograms are prepared by directly impressing them into aluminum and other hard metal substrates, without the need to preheat or otherwise soften the substrate. A holographic embossing shim is prepared from a master and possesses a unique combination of surface configuration, hardness, and strength. The embossing shim can be mounted on a cylindrical support. In one embodiment, the shim is used to emboss a hardenable material, which is later hardened to form a tool.
