A monitor comprises circuitry to receive a signal and process the signal to monitor at least one characteristic of a subject, and a flexible polymer casing forming a waterproof enclosure for the circuitry. The flexible polymer casing is infused with a conductive material at at least one location to form at least one infused electrode that extends from an exterior of the flexible polymer casing to an interior of the flexible polymer casing, and the at least one infused electrode is coupled to the circuitry so as to allow the signal to pass from outside the flexible polymer casing to the circuitry. A polymer in a portion of the flexible polymer casing that is infused with the conductive material at the at least one location is cross-linked with a polymer in a portion of the flexible polymer casing that is not infused with the conductive material.

Systems, devices, methods, and kits for monitoring one or more physiologic and/or physical signals from a subject are disclosed. A system including a head mounted display to monitor one or more physiologic signals from the face or head of the subject is disclosed. A method for analyzing an ocular parameter of the subject to determine a sympathetic and a parasympathetic outflow thereto is disclosed.

Methods and systems are disclosed including a light system comprising a pad assembly comprising: a pad having a first side and a second side opposite the first side, the first side having an adhesive thereon; and a post with a proximal end connected to the second side of the pad and extending to a rounded distal end; and a light assembly attachable to and rotatable about the rounded distal end of the post of the pad assembly, the light assembly comprising: a case having an opening, the opening structured to rotatably accept the rounded distal end of the post of the pad assembly; one or more light emitting diode at least partially within the case and positioned to illuminate an area outside of the case.

An electric conductive sensing device is provided. A front sheet of a sensing pad has several openings. A sensing electrode is a conductive ink electrode aligned with and exposed through each opening. Several first terminals are formed on an insert portion of the sensing pad and are connected to sensing electrodes. Each opening covered by a conductive gel is electrically connected to the corresponding sensing electrode. The insert portion is integrated in a connector. The present invention can be used as electrode patches of ECG devices or electric stimulators. In use, the connector is plugged into the devices to transmit tiny electrical currents to the ECG device from human skin surface, or to transmit electrical currents generated from the stimulator to human. The sensing electrodes are formed by conductive ink printing thereby simplifying the manufacturing process and lowering the manufacturing cost compared to conventional soldered structures.

An envelope is comprised of two sheets of material that are placed one on top of each other with their interior sides facing each other with their edges sealed to each other with an adhesive to form an airtight enclosure. The envelope has at least one medical patch inside it that is attached to the interior side of at least one of the sheets and a layer of medical grade pressure sensitive adhesive surrounding the at least one medical patch. The pressure sensitive adhesive is applied to a part of the surface of the interior side of the sheet in order to attach the sheet of material and the at least one medical patch to the body of a patient. The medical patch can be an electrode for measuring a patient's vital signs or delivering an electric shock or a transdermal patch for delivering a drug to a patient.

An electrode includes an electrically non-conductive support. A protruding, electrically conductive attachment element with an attachment site for the releasable attachment of a signal conductor is on an upper face of the support. A conductor is on the underside of the support, and is electrically connected to the attachment element and to a contact medium. The conductor and the contact medium are arranged on the underside of the support. An imaginary normal to the support, running through the attachment element, runs through the conductor or a recess in the conductor and through the contact medium or a recess in the contact medium. The conductor has on its surface a redox pair suitable for the depolarization of the electrode. The attachment element has a projection reaching through the support with a widened region at its end, and the conductor is arranged between the widened region and the support.

A monitor recorder-implemented method for electrocardiography value encoding and compression is provided. A plurality of codes are maintained, each associated with an electrocardiography value range. A series of electrocardiography values is obtained. A serial accumulator is set to a predetermined value; each of the obtained electrocardiography values from the series of the obtained electrocardiography values is processed, including: performing a mathematical operation on that obtained electrocardiography value and the serial accumulator; identifying the code within the range associated with which a result of the mathematical operation falls; representing that obtained electrography value with the identified code; and adjusting the serial accumulator by a value derived from the range associated with the identified code. Each of the represented codes are into a sequence in a non-volatile memory.
