摘要： A method for an adaptive forward error correction (FEC) in a passive optical network. The method comprises selecting an initial downstream FEC code to be applied on downstream data transmitted from an optical line terminal (OLT) to a plurality of optical network units (ONUs) of the PON; communicating the selected downstream FEC code to the plurality of ONUs; receiving at least one downstream bit error ratio (BER) value from at least one ONU of the plurality of ONUs, wherein the downstream BER value is measured respective to downstream data received at the at least one ONU; changing the selected downstream FEC code to a new downstream FEC code based on a plurality of downstream BER values measured by the at least one ONU; and communicating the new downstream FEC code to the plurality of ONUs.

摘要： An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device having four electrodes on an outer surface thereof, the handheld device having an extended configuration and a storage configuration. The apparatus also includes a controller configured to measure signals between the electrodes to provide signals that are used to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces. When the handheld device is in the extended configuration and the first and second electrodes contact a first hand of a patient such that the first and second electrodes contact different locations on the first hand, the third electrode is in contact with a location on the patient's other hand and the fourth electrode contacts a point on the patient's body that depends on the particular trace being measured.

摘要： A method for generating an ECG measurement associated with a point on a patient's body such as one of the precordial points is disclosed for use with an apparatus that cannot make contact with the leg and the point simultaneously. The method includes simultaneously recording a hand signal and a leg signal during a first time period. The hand signal is also measured during a second time period together with a chest signal corresponding to one of the precordial points. A signal representing the leg signal in the second time period is then computed from the first time period data. A reference signal is then generated from the hand signal and computed leg signal during the second time period. The reference signal is then combined with the chest signal to provide the corresponding precordial signal.

摘要： An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device and a controller. The handheld device has first, second, third, and fourth electrodes on an outer surface of the handheld device. The controller records signals from the first, second, third, and fourth electrodes and generates an ECG recording from the signals. The controller also provides placement information regarding locations on a user's body that are to be brought into contact with the first, second, third, and fourth electrodes while the controller records the signals. The handheld device can include a cellular telephone or a PDA. The controller stores an exemplary normal ECG recording, and compares a newly generated ECG recording with the stored ECG recording and generates an indication that indicates whether the newly generated ECG recording is consistent with the stored ECG recording.
