摘要： In described embodiments, a data collection device receives signals from one or more patient monitoring devices, the signals representing patient data and other vital signs measured at a patient. The data collection device employs statistical quality algorithms to track irregular behavior and out-of-bound events, the behavior and events either being pre-set, adaptively set, or otherwise defined within pre-determined limits. The data collection device communicates alerting signals to a caregiver's handheld device when the irregular behavior and out-of-bound events occur. The alerting signals contain information related to the patient data, irregular behavior and out-of-bound events, thereby allowing a caregiver to take appropriate action.

摘要： In described embodiments, a transceiver includes an eye monitor, clock and data recovery, and adaptation modules. Data sampling clock phase and error clock phase determined from a data eye are decoupled in the transceiver during a sampling phase correction process. Decoupling these clock phases during the sampling phase correction process allows relative optimization of system equalization parameters without degradation of various adaptation algorithms. Such adaptation algorithms might be employed for received signal gain and equalization such as, for example, Decision Feedback Equalizer (DFE) adaptation. Deriving the data sampling clock and error clock phases from the same clock generation source and with independent clock control enables an iterative sampling phase correction process that allows for accelerated clock and data recovery (CDR) without disturbing the data eye shape.

摘要： A receiver has an input and a decision feedback equalizer (DFE). The DFE couples to the receiver input and has at least one tap coefficient. An input signal, having a first amplitude level insufficient to cause significant non-linear distortion in the receiver, is applied to the receiver input. After the DFE adapts to the applied input signal having the first amplitude level by adjusting the at least one tap coefficient, the adaptation process is stopped. Then the at least one tap coefficient is scaled by a factor α and the amplitude of input signal is adjusted to a second amplitude level greater than the first amplitude level by the scale factor α. Although the second amplitude level might be sufficient to cause significant non-linear distortion in the receiver, the scaled tap coefficient has the correct values for proper DFE operation in the presence of the non-linear distortion.

摘要： In described embodiments, elements of a wireless home network employ learned power security for the network. An access point, router, or other wireless base station emits and receives signals having corresponding signal strengths. Wireless devices coupled to the base station through a radio link are moved through the home network at boundary points of the home and the signal strength is measured at each device and communicated to the base station. Based on the signal strength information from the emitted signals measured at the boundary points and/or from measured signal strength information of signals received from the boundary points, the base station determines a network secure area. The base station declines permission of devices attempting to use or join the home network that exhibit signal strength characteristics less than boundary values for the network secure area.

摘要： In described embodiments, a transceiver supports two or more rates using an oversampling clock and data recovery (CDR) circuit sampling high rate data with a predetermined CDR sampling clock. A timing recovery circuit detects and accounts for extra or missing samples when oversampling lower rate data. An edge detector detects each actual data symbol edge and provides for an edge decision offset in a current instant's block of samples. An edge error is generated from the previous instant's actual and calculated edges; and an edge distance between actual edges of the current and previous instants is generated. Filtered edge distance and error are combined to generate a calculated edge position for the data symbol edge for the current instant. The edge decision offset is applied to the current calculated edge position to identify a sample value to generate a decision for the data symbol to detect the current data value.

摘要： In described embodiments, filter parameters for a filter applied to a signal in, for example, a Serializer/De-serializer (SerDes) receiver and/or transmitter are generated based on real-time monitoring of a data eye. The real-time eye monitor monitors data eye characteristics of the signal present in a data path, the data path applying the filter to the signal. The eye monitor generates eye statistics from the monitored data eye characteristics and an adaptive controller generates a set of parameters for the filter of the data path for statistical calibration of the data eye, wherein the eye monitor continuously monitors the data eye and the adaptive controller continuously generates the set of parameters based on the eye statistics.

摘要： In described embodiments, a transceiver includes an eye monitor and margin detector having one or more samplers with corresponding logic. One or more programmable provisioning parameters are defined based on a pre-defined minimum target operating margin for acceptable noise and jitter margins. For example, two programmable provisioning parameters, phase and voltage, correspond with thresholds for margin samplers placed within the eye. Initially, the transceiver applies equalization, after which an inner eye of the transceiver, as detected by the eye monitor, is relatively open with some margin for supporting channels. If the receiver margin goes below this target margin, the eye closes, which is registered by the samplers. In the presence of spectrally rich input data, if the receiver margin goes below this target margin, an updated adaptation of equalizer or other circuit parameters might be initiated; else, adaptation is not generally required.
