The supporting member supports the electrode group such that contacting surfaces of the electrodes with respect to a living body are arranged substantially on an identical plane. The electrodes are arranged lined in a direction an artery extends when the pulse wave measurement electrode unit is ...
The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches...
It killed almost one million people and caused a lot of damage. We measure an earthquake’s strength on the Richter Scale. The Richter Scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more ...
Provided an antenna apparatus for use with a portable terminal, the apparatus may be used in different frequency bands by a combination of antenna characteristics. A whip antenna feeder 3 is connected via electrical contact with the power member 5, and the resonance occurs when stretched in the ...
This results in a very power and area efficient FPU design, supporting a chip frequency of 4.14 GHz. A single 64-bit FPU instance measures only 0.26 mm2 in 45nm CMOS SOI. 展开 关键词: FPU heterogeneous precision support subnormal check IEEE 754-2008 compliant high-frequency design ...
In the context of waves, frequency is the number of complete wave cycles that occur in a given time period. Therefore, longer wavelengths indicate a lower frequency, as there are fewer complete wave cycles occurring within a specific time frame. Rate this question: 4. Shorter wave lengths ...
电工电子专业英语(第2版)Module A Unit 1-10-修改.ppt,Notes 法拉第(1791-1867),英国的化学家和物理学家,是当时最伟大的实验学家。电动机和发电机的运行都是基于法拉第电磁感应原理。为了纪念这位科学家,人们以他的名字“法拉”作为电容的单位。 Real Knowledge, lik
programmable flash memory and 4 kB of RAM. The microcontroller combines the advantages of the features of the CC1101 sub-1 GHz RF radio module with the MSP430 CPUXV2. The MSP430 CPU has a 16-bit reduced instruction set computer (RISC) architecture with a clocking frequency of up to 20 ...
Each satellite contains four "atomic clocks," which vibrate at a precise frequency, according to the laws of the quantum theory. 开车最头疼的两大麻烦是迷路和交通堵塞。虽然计算机革命不可能彻底解决这两个问题,但却会带来积极的影响。你汽车上与绕轨道运行的卫星发出的无线电信号调谐的传感器能随时精确地...
A rolling bearing unit having undulation on the rolling surfaces of the rolling elements where the total value of the wave components having an even number of waves per circumference is smaller than the total value of the wave components having an odd number of waves per circumference, or having...
