Telemetry Receivers
Telemetry, literally meaning "remote measurement" or remote
collection of data is the study and measurement of the transmission
of data over certain mediums. Despite the wealth of probable
applications the primary purpose of telemetry is automated data
collection at a place, which is inaccessible, inconvenient or
dangerous, such as satellites in orbit, and relay the data to
telemetry receivers on ground where the data is monitored,
interpreted and recorded. Telemeter is the apparatus used for
recording the readings of an instrument and transmitting them by
radio. A telemetry handler, collects, formats and stores the data in
a dedicated buffer, and then relays it to telemetry receivers.
Telemetry is expected to replace bar coding when the price point
reaches an affordable level. Product information can be stored on
specialized telemetry tags that will track the product along the
supply chain and relay the information to telemetry receivers.
Combined with local technology, the company assets can be located at
any point in time. Thus, telemetry monitor will allow companies to
wirelessly access information and monitor status levels at all
times.
Telemetry also permits the tracking of endangered land and aquatic
species tagged with telemetry devices, in order to get information
on their patterns of movement, dispersal and migrations, and habitat
use. Telemetry receivers are also used as an aid to understand and
identify the natural causes that are linked to habitat conditions of
these animals, which in turn alter their behavior, and how such
conditions affect their mortality rates.
Since the early 1970s, the use of telemetry receivers to provide
real time physiological monitoring in coronary care units has become
widely recognized. These systems are used for monitoring of the
electro-physiological state of patients who are at risk of abnormal
heart activity. These patients are outfitted with customized
telemetry devices without any other control, except an On/Off
button. This device comprises a wireless receiver for the
long-distance telemetry and a GSM module. If the patient is
suffering from a critical condition, alert messages are relayed via
the standard SMS (short messaging system) protocol to the central
database, where they are allocated to the healthcare professional in
charge of the patient.
