A connection cable is disclosed for controlling a voltage-controlled generator such as an electrosurgery generator from a controlling device such as a robotic surgery system. The cable includes a first connector adapted to connect to a voltage-controlled generator and a second connector adapted to connect to a controlling device. Within the cable is a voltage divider interdisposed between the first connector and the second connector. The voltage divider is configured to divide a reference voltage provided by the voltage-controlled generator into at least one control voltage which is selectable by the controlling device. The cable additionally includes a plurality of electrical wires which operatively connect the first connector, the second connector and the voltage divider. During robotic electrosurgery, said operating parameters can be actuated by a surgeon operating at the robotic surgical system console, which causes a corresponding control voltage to be switched to a control voltage input on an electrosurgery generator, which, in turn, generates a corresponding electrosurgical signal in response thereto.

Apparatus and methods according to the present invention preferably utilize electroosmotic pumps that are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. These electroosmotic pumps are preferably fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These electroosmotic pumps also preferably allow for recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. Apparatus and methods according to the present invention also allow active regulation of the temperature of the device through electrical control of the flow through the pump and can utilize multiple cooling loops to allow independent regulation of the special and temporal characteristics of the device temperature profiles. Novel microchannel structures are also described.

Downhole cables are described that are configured to protect internal structures that may be detrimentally impacted by exposure to the downhole environment, by protecting such structures by at least two protective layers. In some examples, the structures to be protected may be housed in a protective tube housed within the protective outer sheath. The described configuration enables the use of structures such as polymer fibers in the cables for strength and load-bearing capability by protecting the fibers, by multiple protective layers, from exposure to gases or fluids within a wellbore.

Methods and apparatuses for electrically connecting a medical glucose monitor to a glucose sensor set, as well as for testing the operation of the glucose monitor, monitor cable and glucose sensor set are provided. In one embodiment, an electric cable comprises a cable member, a first connector and a second connector. The cable member in turn comprises at least one insulated conductor, a conductive shielding layer disposed around the at least one insulated conductor; and an insulating layer disposed around the conductive shielding layer. A glucose monitoring system test plug provides for a releasable electrical connection with the electric cable. In one embodiment, the test plug comprises a housing and a fitting affixed thereto which is adapted to electrically couple the test plug with the electric cable. The test plug further includes an electrical circuit that produces a signal that is read by the glucose monitor to test the operational performance of the glucose monitor and the electric cable when the test plug is coupled to the electric cable and when the electric cable is coupled to the glucose monitor.

There is elucidated a device (10) comprising first and second magnetic cores (30, 40; 30a, 30b, 30c, 40a, 40b, 40c) forming a magnetic circuit. The circuit includes a first set of electrical windings (300, 310) for magnetically coupling a first electrical signal through the device (10) via a first magnetic path (350) in the circuit. The circuit includes a second set of electrical windings (400, 410) for magnetically coupling a second electrical signal through the device (10) via a second magnetic path (450) in the circuit. The paths (350, 450) are partially spatially intersecting. The sets of windings (300, 310, 400, 410) are configured so that: (a) the first set of windings (300, 310) is sensitive to magnetic flux in the first magnetic path (350), and insensitive to magnetic flux in the second magnetic path (450); and (b) the second set of windings (400, 410) is sensitive to magnetic flux in the second magnetic path (450), and insensitive to magnetic flux in the first magnetic path (350). The first and second cores (30, 40; 30a, 30b, 30c, 40a, 40b, 40c) enable relative motion (50) there between whilst coupling the signals through the circuit. The device (10) is beneficially employed in a medical system (800).
