Abstract: A control system using a genetic analyzer based on discrete constraints is described. In one embodiment, a genetic algorithm with step-coded chromosomes is used to develop a teaching signal that provides good control qualities for a controller with discrete constraints, such as, for example, a step-constrained controller. In one embodiment, the control system uses a fitness (performance) function that is based on the physical laws of minimum entropy. In one embodiment, the genetic analyzer is used in an off-line mode to develop a teaching signal for a fuzzy logic classifier system that develops a knowledge base. The teaching signal can be approximated online by a fuzzy controller that operates using knowledge from the knowledge base. The control system can be used to control complex plants described by nonlinear, unstable, dissipative models. In one embodiment, the step-constrained control system is configured to control stepping motors.

Abstract: An electronic device operation method and apparatus. A current state of a device such as TVs or VCRs is indicated as a graphic moving picture of a familiar character shape. Pictures containing an associated character shape are stored in correspondence with a various states of the electronic device. The pictures are formed of fonts each of which has a predetermined magnitude and corresponds to a block of the picture. One or more fonts are read during the time of shifting a device state according to a user key input, and the fonts are changed at time intervals to display a moving picture. A sound corresponding to the moving picture may be output together with the displayed moving picture, to further enhance the device state indication. Thus, a current state of the electronic device is more recognized by persons who do not read characters.

Abstract: A home automation system and method for automatic control of controlled devices throughout a home. A unique architecture of occupancy sensors includes entry/exit sensors for detecting movement through doorways that separate rooms in the home, room motion sensors for detecting room occupancy, spot sensors to detect occupancy of specific locations within the rooms, and house status sensors to detect the status of certain parameters of the home. A central controller communicates with the sensors and controlled objects over a communications network, where the sensors and controlled objects can be added to the system in a ‘plug and play’ manner. The central controller controls the controlled objects in response to the entry/exit sensors, room motion sensors, spot sensors and the house status sensors.

Abstract: An apparatus, a method and a computer system can be used to reduce power consumption of one or more processors in response to a failure condition such as an overtemperature condition affecting the processor or processors. A signal is provided which indicates a failure condition affecting the processor such as an overtemperature condition or a failure or reduction in performance of a cooling mechanism. In response to the signal, a power consumption of the processor is periodically reduced. This can be accomplished by providing a periodic signal to an input of the processor (e.g., a stop clock input or a processor enable input). The processor reduces power consumption by stopping an internal clock of the processor, for example. The periodic signal can be provided to the input of the processor to periodically reduce power consumption.

Abstract: There is provided a switching circuit for unit duplication boards designated as a working board and a protection board. In each duplication board, a software block is maintained reset at an initial hardware operation and determines the activation or deactivation state of a board according to a software command received from a central processing unit (CPU), a hardware block monitors a clock signal received from the other board using a system clock signal for the board and determines a time point when the system clock is to be activated according to the monitoring result, and a hardware board state block determines the working or protection state of the board in hardware terms, reflecting the states of the board and the other board during hardware operation. One of the unit duplication boards is automatically set to a working mode at an initial hardware operation, for hardware switching.

An output-select button is used to specify which output plug is to be used by the source device.

Abstract: A method and apparatus controls fans and power supplies to provide accelerated run-in testing. By modulating fans to increase case temperatures and adjusting power supplies to provide “worst case” voltages, a computer system can be subjected to a run-in tests under taxing conditions. By alternately cooling and heating devices such as CPUs, devices can be subjected to mechanical stresses associated with power-on/power off cycles. A time based test implements the present invention based on time, and a temperature based test implements the present invention based on temperature. The present invention can be used to implement a run-in test in which the computer system is operated at an elevated temperature, thereby achieving results similar to those achieved by performing a run-in test in an environmental chamber at an elevated temperature. Alternatively, the a run-in test can be performed by repeatedly cycling the temperature between relatively high and low values.

In an aspect of the invention, the industrial controller has a memory module having at least RAM and flash memory. Savings of the state and context is accomplished through writing an image of the RAM to flash memory prior to the power being removed from the RAM. Restoring is accomplished through writing the RAM image in the flash memory back to the RAM after the RAM has been energized.

Abstract: Methods, devices, and systems for monitoring the status of a computer through a driverless device node port, such as a universal serial bus port or P/S 2 port, are disclosed. A driverless device node is emulated and presents a message to the operating system of the computer through the device node port. The message requires a response from the operating system, and the time taken for the response to be generated is detected. From the detected time, the status of the computer can be found. A status indication may be transmitted from a remote management device emulating the driverless device node to a remote management computer so that the condition of the computer can be monitored remotely.

Abstract: A method and system of controlling devices with digitally stored content. Devices such as home electronic appliances, lighting systems, heating, ventilating and air conditioning (HVAC) equipment, home security systems and home entertainment systems are controlled from a single, centralized device. A set top box (STB) stores scripts that include program content for controlling the operation of a plurality of these devices from the STB. A user of the STB selects the desired scripts, and the STB accesses the selected scripts from storage based on a triggering mechanism such as time, content, event, etc. The STB selectively controls operation of certain devices designated in the script. The method provides ease of control over multiple and diverse devices, applications and media within a user's own home environment, with more functionality and flexibility than currently available.

Abstract: The present invention provides a method and system to monitor the statuses of devices that can operate and transmit current device status information to a storage location. The present invention also provides a method to manage and initiate sets of instructions that will be performed by devices in response to a set of current statuses of one or more devices. Each set of instructions is known as a “workflow routine”. Each workflow routine will be based on a set device statuses. This set of device statuses can be referred as a device scenario. When a status of a device changes, the workflow manager of the present invention will check the statuses of the devices in the scenario to determine if the scenario conditions for the initiation of a specified workflow have been met. When the conditions have been met, the workflow routine will be initiated and perform a set of instructions which could lead to the performance of some activity by one or more devices in the network.
