摘要： A system and method for wireless communication. The system can include a transmitter that transmits a data signal having a time period without data transmission. The system can also include a receiver including a first antenna, a second antenna, a switch that activates one of the first antenna and the second antenna, and a processor that estimates a first signal-to-noise ratio for the first antenna and a second signal-to-noise ratio for the second antenna during the time period without data transmission. The processor can control the switch to select one of the first antenna and the second antenna based on a comparison between the first signal-to-noise ratio and the second signal-to-noise ratio.

摘要： A method for monitoring a subject can include acquiring data from the subject, and dynamically adjusting an alarm limit based on the data. The method can also comprise determining a first value that is typical for the subject for the characteristic being monitored, determining a second value for the characteristic being monitored, and generating a comparison based on the two values. The method could also comprise setting a threshold for a characteristic being monitored, and decreasing the alarm limit if the data crosses the threshold. The method could also include setting an extremity limit. The following methods can be applied to the monitoring of a healthcare patient, or other subjects of interest. Also, the values used in the monitoring of the subject can be configured to be transferable from one monitor to another.

摘要： A system for tracking a subject of interest in a location is disclosed. The system is used with subjects who have an identification device having a unique signal identifier. The system comprises a wireless proximity detector capable of detecting the signal identifier; a monitoring unit that monitors the proximity detector by monitoring which signal identifier has been detected by the proximity detector, the monitoring unit generating a data signal representative of which signal identifier has been detected; and a data output unit that generates location data based upon the data signal. The information can be displayed graphically or as a list and can be sorted by various criteria. The display can provide many options to make the display more useful. Also disclosed is a method for tracking a subject of interest using a unique signal identifier. Additionally, a display to be used with the system is disclosed.

摘要： A method and apparatus for reducing noise and detecting electrode faults in a physiological activity acquisition system. The method includes the act of delivering a carrier signal through an electrode connected to a subject. Once the carrier signal is delivered, a combined signal having an electrical-activity portion and a carrier-signal portion is sensed by at least one signal sensing electrode attached to the subject. A low-pass, finite impulse response filter, having a first zero point frequency substantially the same as the carrier signal, separates the carrier signal portion from the electrical activity portion. An impedance value for the sensing electrode is calculated using the carrier signal portion. The calculated impedance value is compared against a known value to determine whether an electrode fault exists.

摘要： An object location monitoring system includes beacons that are spatially distributed throughout an area to be monitored. The beacons transmit interrogation signals that are received and echoed by transponders that attach to moveable objects. Each beacon retransmits its interrogation signal, and any transponder response thereto, to a receiver that measures a time difference between the two signals. This time difference reflects the signal propagation time, and thus the distance, between the beacon and the transponder. One such receiver preferably analyzes the retransmitted signals of multiple (e.g., 50 to 100) beacons. A triangulation method is used to determine the location of each transponder based on the transponder's distances from a set of beacons. In one embodiment, the transponders are provided as or within disposable ID bracelets worn by patients, and are used to track the locations of the patients within a hospital.

摘要： A method of displaying a representation of a physiological signal produced by a patient. The method includes the acts of obtaining a portion of at least one physiological signal acquired from the patient, determining an area to display, and constructing a virtual image representing at least a portion of the patient. The virtual image including (M) polygonal areas. The method further includes transforming the obtained signal to a plurality of values, assigning each value to one of the (M) polygonal areas, assigning a visual characteristic to each polygonal area based in part on the assigned values, and displaying at least a portion of the virtual image including the assigned visual characteristics. The invention further provides a method of optimal feature selection for the classification of the physiological signals produced by a patient.

摘要： A system for use in a monitoring a plurality of subjects may be configured to receive data from a monitoring device, determine whether a subject has a condition that may require attention based on data received from the monitoring device, wirelessly send a notification message to a first portable electronic device and/or a second portable electronic device if a subject has a condition that may require attention, and facilitate voice communication between the first portable device and the second portable device. The voice data may be transferred using one of a network of the health care facility, a direct wireless connection between the portable devices, and a cellular network. The system may further be configured to forward other data from the first portable device to the second portable device, such as data associated with a notification message being displayed on one of the devices.

摘要： Image data is compressed by decomposing the image data into a plurality of resolutions or sized by wavelet decomposition, followed by compression of the resulting data sets. Adaptive Huffman code compression is optimized for compressing the data sets, predictive errors for a low frequency band and the wavelet transformed values for high frequency bands. The image data is thus compressed losslessly and in multiple resolutions such that desired resolution images can be reconstructed and transmitted in accordance with available-bandwidth and viewing capabilities.
