Vertical MEMS Resonators for Real-Time Clock Applications
"... MEMS resonators are today widely investigated as a desirable alternative to quartz resonators in real-time clock applications, because of their low-cost, integration capability properties. Nevertheless, MEMS resonators performances are still not competitive, especially in terms of frequency stabili ..."

Tunable Piezoelectric MEMS Resonators for Real-Time Clock
"... Abstract—This paper reports on the design, simulation and characterization of small form factor, tunable piezoelectric MEMS resonators for real time clock applications (32.768 kHz). The structures were fabricated on a thin-film AlN-on-SOI substrate to enable piezoelectric actuation of an out-of-plan ..."

, 2002
"... application processes with an approximate real-time notion. This time notion is very versatile. At one extreme, it behaves at least as virtual time (being thereby consistent with causality). At the other extreme, it behaves as real-time. More precisely, with respect to approximate real-time all sche ..."

APPLICATION NOTE 4641 Real-Time Clock Adds Accurate Timekeeping to
, 2012
"... Abstract: The MAXQ610 microcontroller does not include a battery-backed real-time clock (RTC), but the flexibility of the 1-Wire® network makes it straightforward to add a DS1904 RTC iButton ® to any MAXQ610-based application. Communicating with the DS1904, setting the clock and control values, and ..."

Design and Development of Real Time Clock based efficient Solar Tracking System
"... The growth or energy demand in response to industrialization, urbanization, and societal affluence has led to an extremely uneven global distribution of primary energy consumption. The sun, wind, waves and geothermal heat are renewable energy sources that will never run out. They are perpetual, or s ..."

. To maximize the power output from solar panels, we need to keep the panels aligned with the sun. In this paper, the design of an efficient solar tracking system based on Real Time Clock (RTC) using ARM processor is described. The proposed tracking system is a low cost, high accurate, more efficient with low

"... Clock skew is one of the significant issues of real-time networking. We have previously proposed a new algorithm for clock skew detection that operates one a one-way measurement, simply based on time stamped packets. This algorithm was initially targeted to Internet transport context. It has been sh ..."
