An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

Analyte Monitoring Device And Methods Of Use

The present invention is generally directed to a system for monitoring a variety of environmental and/or other conditions within a defined remotely located region. In one aspect, a system is configured to monitor utility meters (613) in a defined area. The system is implemented by using a plurality of wireless transmitters (614), each integrated into a sensor (612) adapted to monitor a particular data input. The system also includes a plurality of transceivers (221) that are dispersed throughout the region at defined locations. The system uses a local gateway (210) to translate and transfer information from the transmitters to a dedicated computer (260) on a network (230). The dedicated computer collects, compiles and stores the data for retrieval upon client demand across the network. The computer further includes means for evaluating the received information and identifying an appropriate control signal to be applied at a designated actuator.

System and method for monitoring and controlling remote devices

A system for communicating with a medical device (10) implanted in an ambulatory patient and for locating the patient in order to selectively monitor device function, alter device operating parameters and modes and provide emergency assistance to and communications with a patient (10). The implanted device (10) includes a telemetry transceiver for communicating data and operating instructions between the implanted device and an external patient communications control device (20) that is either worn by or located in proximity of the patient within the implanted device transceiving range. The control device preferably includes a communication link with a remote medical support network (50), a global positioning satellite (80) receiver for receiving positioning data identifying the global position of the control device, and a patient activated link for permitting patient initiated personal communication with the medical support network (50). A system controller (24) in the control device (20) controls data and voice communications for selectively transmitting patient initiated personal communications and global positioning data to the medical support network (50), and for receiving and initiating re-programming of the implanted device operating modes and parameters in response to instructions received from the medical support network (50). The communications link between the medical support network and the patient communications control device may comprise a worldwide satellite network, hard-wired telephone network, a cellular telephone network (82) or other personal communications system.

Worldwide patient location and data telemetry system for implantable medical devices

A system for remotely monitoring an individual. The system includes a server system for generating a script program from a set of queries. The script program is executable by a remote apparatus that displays information and/or a set of queries to the individual through a user interface. Responses to the queries that are entered through the user interface together with individual identification information are sent from the remote apparatus to the server system across a communication network. The server system also includes an automated answering service for providing a series of questions from a stored set of questions for an individual at the remote apparatus to respond to, storing responses to each provided question in the series of questions and providing a service based on the individual's response to the questions.

Networked system for interactive communication and remote monitoring of individuals

A system and method is described that enables a health care provider to monitor and manage a health condition of a patient. The system includes a health care provider apparatus operated by a health care provider and a remotely programmable patient apparatus that is operated by a patient. The health care provider develops a script program using the health care provider apparatus and then sends the script program to a remotely programmable patient apparatus through a communication network such as the World Wide Web. The script program is a computer-executable patient protocol that provides information to the patient about the patient's health condition and that interactively monitors the patient health condition by asking the patient questions and by receiving answers to those questions. The answers to these health related questions are then forwarded as patient data from the remotely programmable patient apparatus to the health care provider apparatus through the communication network. The patient data may also include information supplied by a physiological monitoring device such as a blood glucose monitor that is connected to the remotely programmable patient apparatus. When the patient data arrives at the health care provider apparatus, the patient data is processed for further management of the patient's health condition by the health care provider, such as forwarding another script program to the remotely programmable patient apparatus.

Remote health monitoring and maintenance system

Information signals taken directly from an implanted pacemaker or remotely by way of a telephone circuit are furnished to a computer which processes the information and displays it in digital form in terms of the pacemaker''s stimulus pulse rate or, alternatively, in terms of the interval between pulses. The existing rate or interval is compared with prior measurements and is used to determine the pacemaker''s residual battery life.

Cardiac pacemaker rate/interval computer system

A method and apparatus are disclosed for monitoring a plurality of signal sources to detect the time of occurrence of a change in signal condition from any of the signal sources, the sign of the change and the signal source generating the change. The monitoring is performed by source-associated receivers which generate an ''''event flag'''' upon occurrence of a change in signal condition. The outputs of each receiver are combined in intermediate level selectors for use by a master level selector to enable an address scanner to search the level selectors for the receiver generating the ''''event flag'''' and to record the time of occurrence of the ''''event flag.'''' When the particular receiver which generated the ''''event flag'''' is found, its address and the sense of the change are also recorded.

Data acquisition and identification system

An asynchronous analog to logic level signal converter is described as comprising a first differential amplifier with means for integrating an input analog signal and applying the integrand signal to a second differential amplifier to produce a logic level output signal having a period, T1, inversely proportional to the amplitude of the input signal. A reference signal controllably applied to the other differential inputs of the first and second differential amplifiers produces a changed logic level having a period, T2, inversely proportional to the difference in amplitudes between the reference signal and the input signal. The amplitude of the input analog signal is obtained by computing the product of the reference voltage and the ratio of T2 to T1 plus T2.
