A system and method for secure remote control of a machine includes transmitting video data from a camera on the machine to an operator controller located at a remote operation station, and receiving, at a machine controller of the machine, an operator control message from the operator controller. The operator control message is based on an input device actuated in response to the video data. The method further includes confirming validity of the operator control message based, at least in part, on the video data transmitted from the camera to the operator controller, and controlling the machine with the operator control message when validity of the operator control message is confirmed.

An instruction-storage machine holds instructions that, when executed by a logic machine, cause the logic machine to find a human subject in depth data acquired with one or more depth cameras arranged to image an environment, and to compute an aspect of the human subject from the depth data. Based on the computed aspect, the logic machine determines a change to be made in the environment and actuates appropriate hardware in the environment to make the change.

A system for controlling a fan is provided, which includes a processor, a driver, a power supply module, an instruction output module and a level control module. The power supply module is configured to supply power to the level control module when the server is started up and when the server is shut down. The instruction output module is configured to output a mode control instruction. The level control module is configured to output a first level to the PWM pin and output a second level to the TACH pin based on the mode control instruction and then control the power supply module to supply power to the processor and the driver. The processor is configured to determine a mode of the fan based on the first level and the second level and control a rotation speed of the fan based on the mode of the fan.

An aspect of some embodiments of the current invention relates to a device, that may ignite a substance without the user directly causing the ignition. for example, the device may perform ignition in a manner that does not transgress Jewish religious prohibitions, for example the Jewish religious law prohibits kindling a flame on the Sabbath and/or festivals. In some cases, kindling may be permitted in an indirect manner referred to in Jewish law by the Aramaic term “Grama”. For example, the device may be designed to ignite a cigarette. Optionally, the device may be designed to be carried safely in a pocket. In some embodiments, the device may initiate ignition without direct user action and/or the initial ignition may be used to ignite another object in accordance with Jewish law allowing transfer of fire but prohibiting starting of a new fire on a holiday.
