Numerous aspects of communication devices, methods, and systems are described in this application. One aspect is an apparatus comprising a plurality of energy generators arrangeable on or adjacent skin. Each energy generator of the plurality of energy generators may be operable to output a plurality of different energy types in a signal direction toward the skin. The plurality of energy generators may be operable to communicate with nerves associated with the skin when arranged on or adjacent the skin by outputting an energy signal in the signal direction with one or more energy types of the plurality of different energy types.

An incontinence detection pad has an RFID tag in which an authentication code, such as an electronic product code (EPC), is stored. A reader in wireless communication with the RFID tag of the incontinence detection pad verifies that the incontinence detection pad is an authorized detection pad. Thus, unauthorized incontinence detection pads that do not have the proper authentication code are not able to be used in an incontinence detection system.

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.

An electrode sheet is capable of suppressing an influence of noise that is applied on a wire, and a biological signal measuring device uses the electrode sheet. The electrode sheet is provided with a sheet, a biological signal receiving electrode formed at the sheet and exposed from the sheet, a biological signal amplifier formed at the sheet, an interface part for connection to an external biological signal processing unit, a first wire that connects the biological signal receiving electrode and an input part of the biological signal amplifier to each other, and a second wire that connects the interface part and an output part of the biological signal amplifier to each other.

A catheter includes an insertion tube, a flexible substrate and one or more electrical devices. The insertion tube is configured for insertion into a patient body. The flexible substrate is configured to wrap around a distal end of the insertion tube and includes electrical interconnections.

Impedance devices with integrated circuit modules and method of using the same to obtain luminal organ information. In one embodiment, a device comprises an elongated body for at least partial insertion into a mammalian luminal organ and having a first conductor extending therethrough, a proximal electrical unit connected to the elongated body to deliver power along the first conductor, and a sensor substrate located at or near a distal end of the elongated body and comprising a circuit module operable and/or configured to direct the sizing portion to obtain sizing data and the pressure sensor to obtain pressure data, and facilitate transmission of the sizing data and/or the pressure data to the proximal electrical unit.

A system and method for display of subcutaneous cardiac monitoring data are provided. Cutaneous action potentials of a patient and other sensed data associated with the patient are recorded as electrocardiogram (EGC) data over a set time period using a subcutaneous insertable cardiac monitor. A set of R-wave peaks is identified within the ECG data and an R-R interval plot is constructed. A difference between recording times of successive pairs of the R-wave peaks in the set is determined. A heart rate associated with each difference is also determined. The pairs of the R-wave peaks and associated heart rate are plotted as the R-R interval plot. A diagnosis of cardiac disorder is facilitated based on patterns of the plotted pairs of the R-wave peaks, the associated heart rates in the R-R interval plot, and background data based on the other sensed data.
