The invention provides a fan control system, which comprises a fan, a control unit, and a fan chip. The fan chip comprises a command table. A first specific pulse pattern represented as a first form of code, and a second specific pulse pattern represented as a second form of code are defined in the fan chip. The command table records at least one control command. Each control command is corresponding to a code string, respectively. When the fan chip receives a series of pulse signals from the control unit, it will determine that the code string is represented by the pulse signals, and inquire the corresponding control command from the command table according to the determinated code string so as to set up at least one operation parameter of the fan chip or control the fan to perform a corresponding operation according to the inquired control command.

A field device for use in a process control system having embedded firmware stored in a a nonvolatile memory. The firmware includes computer-executable instructions for performing fixed behaviors and/or standard measurements as well as a runtime interpreter. The interpreter executes application specific code downloaded to the field device. When executed, the application specific code performs custom field device functions.

A cutting knife assembly includes a motor, a knife, a fixing base and a position adjustment stand. The motor has a converter, the knife has a blade portion and a body portion connected with the blade portion and the converter. The fixing base has a main body having a penetration channel and a screw structure. The knife and the converter are penetrated through the penetration channel, the blade portion is exposed outside the main body, and the screw structure is disposed around the penetration channel. The position adjustment stand has a through hole having an inner screw structure matched with the screw structure. The main body and the through hole are screwed with each other. When the converter is driven by the motor, the knife and the fixing base are rotated by the converter, thereby adjusting an exposed distance. The height of the knife can be precisely adjusted.

A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

An intelligent light bulb is provided as well as a method, devices and computer program product of configuring such an intelligent light bulb. The intelligent light bulb comprises an LED lighting element and a programmable controller. The programmable controller comprises a memory module having stored therein firmware including instructions for controlling operations of the LED lighting element, where the memory module including a passive memory on which at least a portion of the firmware is stored. The passive memory component of the memory module is responsive to a signal carrying firmware update information received over a wireless communication link from a device external to the intelligent light bulb for causing a firmware update process to be performed to modify the instructions of the firmware based on the update information carried by the signal. The programmable controller also includes a processing unit in communication with the memory module for operating the LED lighting element at least in part in accordance with the instructions of the firmware. Advantageously, the proposed intelligent light bulb can be configured using the signal carrying the firmware update information. In some embodiments, this may allow modifications of certain operating characteristic of the intelligent light bulb to be performed after manufacturing, including modifications pertaining to light color emitted and/or manner of operating the light bulb.

A support device executes a maintenance operation for a PLC, and records, into the PLC, information identifying the maintenance operation. The maintenance operation includes at least either of writing and deleting of data such as firmware into/from the PLC. The support device may further record, into the support device itself, information identifying the maintenance operation. In addition, the PLC uses data stored in a recording medium to execute a maintenance operation for the PLC. At this time, the PLC records, into the PLC itself, information identifying the maintenance operation. The PLC may further record, into the recording medium, the information identifying the maintenance operation.

A method for automated configuration of an industrial controller comprises the steps of providing an identification from an industrial controller to a server connected to said industrial controller via a network, said identification identifying said industrial controller, and receiving, from said server via said network, an industrial program and/or a parameter for an industrial program in accordance with said identification.

The universal astronomical instrumentation control system is completely based on an Open Source architecture in the server- and client-side components. The system is self-contained within a single small factor package using embedded hardware architecture. No desktop or server-side components are required. The system creates a WiFi hotspot that enables mobile/tablet/desktop devices to connect to it and control any astronomical devices attached to the unit. Therefore, no external network is required in order to operate the device. The system is not limited to canonical devices. Any device with an INDI (Instrument Neutral Distributed Interface) driver can be controlled by the unit. The system's client software is cross-platform and available on desktop, tablet, and mobile devices. The system is a consumer-level device designed for fast and easy control of commercially popular astronomical equipment.
