Multistage mechanical transmissions with automatic control for advanced trucks and buses

Blokhin A., Nedyalkov A., Barakhtanov L., Taratorkin A., Kropp A.

Acta Mechanica et Automatica

2017

Vol. 11, no. 4

260--266

The study considers the basic trends of development of modern mechanical transmissions of trucks and buses. It provides the developed various series of multispeed transmissions with automatic control and a number of transmissions from 6 to 16 for trucks and buses. The paper shows the basic parameters of the standard series of new transmissions received on the basis of innovative technical solutions. It provides the results of experimental studies of 16-speed transmissions on a special test stand and on the road as part of a truck transmission. Theoretical and experimental data on the gear change time are compared.

Wireless communication for medical applications: the HEARTS experience

Kropp A.

Journal of Telecommunications and Information Technology

2005

nr 4

40-41

Wireless networks provide all the functionality of wire-line networks without the physical constraints of the wire itself giving an interesting alternative to phone-line and powerline wiring systems. With a wireless network, physicians can actively monitor a patient's vital signs from anywhere in a hospital. HEARTS (health early alarm recognition and telemonitoring system) is a research project having the major aim to provide support for prevention and monitoring heart disease, based on advanced technology. The HEARTS idea is to gather biometric and environmental data coming from patients during both hospitalization phase and in their normal lifetime activities, using wireless networks. The wireless network and its composing devices are called personal health network (PHN). WPAN and WLAN technologies have been investigated, each with its pros and cons, for use in health monitoring activities inside hospitals and at home, for improving patient mobility, and to provide patients for "last interconnection hop" to the infrastructure network. Technological and operational problems have been addressed concerning bluetooth, IEEE 802.11b (WiFi), GSM/GPRS/UMTS wireless transports, all of them tested and some of them concretely adopted inside the HEARTS framework.
