20090287103 | SYSTEMS AND METHODS FOR MONITORING PATIENT ACTIVITY AND/OR EXERCISE AND DISPLAYING INFORMATION ABOUT THE SAME - Patient activity and heart rate (HR) are monitored. For each of a plurality of time periods, periods of patient exercise and/or patient activity, if any, are detected based on the monitored patient activity and HR and an activity threshold. A cumulative duration of exercise and/or a cumulative duration of activity is/are determined for each time period, and the peak exercise HR for each period of patient exercise is detected. Information is stored, including duration information indicative of the cumulative duration of exercise and/or the cumulative duration of activity for each time period, and peak exercise information associated with the period of patient exercise during which the highest peak exercise HR occurred for each time period. The stored duration information, or information indicative thereof, are transferred from an implantable system to a non-implanted system so that a graphical representation of such information can be displayed and observed to evaluate exercise compliance and/or heart failure condition. | 11-19-2009 |
20100305641 | SYSTEM AND METHOD FOR DETECTING PULMONARY EDEMA BASED ON IMPEDANCE MEASURED USING AN IMPLANTABLE MEDICAL DEVICE DURING A LEAD MATURATION INTERVAL - Techniques are provided for use by implantable medical devices such as cardiac resynchronization therapy (CRT) devices for detecting pulmonary edema based on transthoracic impedance sensed using cardiac pacing/sensing leads, wherein detection can be performed while lead maturation occurs. Briefly, the implantable device determines whether the leads are within an initial post-implant interval following implant during which lead maturation generally occurs. The device then detects pulmonary edema or related medical conditions within the patient based on transthoracic impedance using a set of detection parameters adjusted for use during the post-implant interval. Thus, rather than “blanking” impedance data during lead maturation, the device instead detects and processes impedance during this period to identify possible episodes of pulmonary edema so that appropriate measures can be undertaken, such as delivery of warnings or titration of appropriate medications. | 12-02-2010 |

20140214110 | SYSTEMS AND METHODS TO MONITOR AND TREAT HEART FAILURE CONDITIONS - An implantable device monitors and treats heart failure, pulmonary edema, and hemodynamic conditions and in some cases applies therapy. In one implementation, the implantable device applies a high-frequency multi-phasic pulse waveform over multiple-vectors through tissue. The waveform has a duration less than the charging time constant of electrode-electrolyte interfaces in vivo to reduce intrusiveness while increasing sensitivity and specificity for trending parameters. The waveform can be multiplexed over multiple vectors and the results cross-correlated or subjected to probabilistic analysis or thresholding schemata to stage heart failure or pulmonary edema. In one implementation, a fractionation morphology of a sensed impedance waveform is used to trend intracardiac pressure to stage heart failure and to regulate cardiac resynchronization therapy. The waveform also provides unintrusive electrode integrity checks and 3-D impedancegrams. | 07-31-2014 |

Blocks can be selected automatically, simultaneously, and/or in sequence based on a memory access request received by the RFID tag. A memory block can be selected for powering based on address data included in or derived from a memory access request. Power to a memory block can be controlled by memory block selector which activates one or more power control transistors associated with memory blocks based on the memory access request. A compatible tag reader can be configured to instruct a tag to power/unpower individual memory blocks. | 08-28-2008 |

20090219141 | PHASE HOPPING TO REDUCE INTERFERENCE AND IMPROVE RADIO FREQUENCY IDENTIFICATION (RFID) TAG THROUGHPUT - A radio frequency identification (RFID) reader outputs an interrogation signal, and hops/varies the phase of the interrogation signal sent by the RFID reader over time. Varying the phase of the interrogation signal enables the RFID reader to provide, for each zone of an RF field of the RFID reader, a particular phase that reduces of the effects of interference RF signal(s) present in that zone of the RF field. Reducing the interference in each zone of the RF field increases the throughput of RFID tags that can be successfully read by the RFID reader. | 09-03-2009 |
20100060423 | Radio frequency identification (RFID) reader with multiple receive channels - A radio-frequency identification (RFID) system includes an RFID tag, an RFID reader, and a controller. The RFID reader employs a plurality of phase-offset or phase-diverse channels to improve detection of data transmitted from the RFID tag to the RFID reader. A controller selects the channel that provides the best signal-to-noise ratio and decodes the data provided by the RFID tag using the selected channel. | 03-11-2010 |
