	A cryogenic complex has been built at IHEP to provide liquid helium and nitrogen for the RF-separator of kaons. About 500 analog parameters and 300 digital signals have to be measured, tens of commands generated, and 20 closed loops activated. On a lower level of the control system there are 90 home made equipment controllers, based on Analog Device and Atmel programmable devices. They provide data acquisition, calculation of operating parameters, and generation of digital and 4-20 mA analog commands. Equipment controllers are connected to four personal computers (PC) by means of CAN field buses. The PCs in turn are connected by a dedicated Ethernet network. LabVIEW based software for control and monitoring of the cryogenic complex has been designed and developed. The paper describes the features and present status of the control electronics, firmware and software.

	The LHCb experiment at the Large Hadron Collider (CERN) has developed a complete high-speed and high-sensitivity background monitor based on a pair of plastic scintillators and a custom-made LHCb readout board to record fast LHC beam losses with time information. The system is installed close to the LHCb Vertex Locator and it has been operational since the LHC pilot run providing valuable information to the LHC Operations crew during beam commissioning and to LHCb Control Room about the experimental conditions at the physics runs. The system is able to record fast beam losses at a rate of 40 MHz, providing information regarding the bunch crossing of the loss, the intensity of the loss calibrated in number of Minimum Ionizing Particles. A full control and monitoring system has been developed as well within the framework of the LHCb Experimental Control System. A complete simulation of the system has been central in converting the response of the system into physical quantities. In this paper we will describe the system in its components and functionalities, the commissioning phase, the simulation framework and the first results with real beam at the LHC.

	A compact medical accelerator of new generation "ELLUS-6M" has been designed and manufactured for radiotherapy by 6MeV photons in the multi-static and arc modes. The gantry can be rotated through ±1850 and ensures setting accuracies of the irradiator rotation velocity and positioning sufficient for the IMRT mode. The computerized control system is compatible with the treatment planning system and allows upgrading by adding new modules. To realize the conformal radiotherapy, the following additional medical equipment has been developed: a multi-leaf collimator a portal vision system for the dose field verification during irradiation and an upgraded treatment table made as a semi-pantograph. In 2010, it is planned to finish clinical tests of the "ELLUS-6M" accelerator with the additional medical equipment in the N. N. Petrov Scientific Research Oncology Institute, Pesochny, St. Petersburg.
