A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as electrocardiography (ECG or EKG).
In 1994 when the "amplifier and mixing functions on the existing transmitters" used six vacuum tubes for each module, [50] Southwest Research Institute was redesigning the transmitters [51] (5 tubes were replaced by solid-state components.) [52] By 1998, the site was providing space surveillance on "38 percent of the near-earth catalogue" of ...
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
The rotation rate of the Earth (Ω = 7.2921 × 10 −5 rad/s) can be calculated as 2π / T radians per second, where T is the rotation period of the Earth which is one sidereal day (23 h 56 min 4.1 s). [2] In the midlatitudes, the typical value for is about 10 −4 rad/s.

EMWIN is also coupled with the High Rate Information Transmission (HRIT) service, which broadcasts low-resolution GOES imagery and selected products to remotely located user HRIT terminals. [ 102 ] Search and Rescue Satellite Aided Tracking (SARSAT) – A SARSAT transponder on GOES-16 can detect distress signals and relay them to local user ...
The satellite was launched to the regular 89.5 degrees west checkout location and will undergo part one of PLT from this location. GOES-18 will then drift to 136.8 west and perform the remainder of PLT at that location near GOES-West. The 0.4 degree offset from GOES-17 will allow X-band RDL downlink from both GOES-17 and GOES-18.
In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children. [57]
