Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: An adaptive networking device including a switch module having several ports and operable according to a first protocol and a repeater module also having several ports and operable according to a second protocol. The adaptive networking device preferably includes several connector ports for coupling to external data devices, such as computers, work stations, file servers, modems, printers, repeaters, switches, routers, hubs, concentrators, or the like, for establishing a networking system. Also, the adaptive networking device preferably includes an interface circuit for each connector port for detecting communication from a data device on the corresponding connector port and for coupling that data device to either the switch module or the repeater module. The interface circuit preferably senses the protocol of the communication and automatically couples the data device to the corresponding and compatible communication module.

Abstract: A network (10) includes several local networks (32, 34, 36). Each local network (32, 34, 36) includes a repeater (12, 16, 20) coupled to data devices (14, 18, 22). The combination of the repeater (12, 16, 20) and the data devices (14, 18, 22) form a collision domain for managing communications within the local network (32, 34, 36). Uplink modules (40, 44) manage communications between the local networks (32, 34, 36) by isolating collision domains and generating collision indications when messages cannot be transmitted. The uplink modules (40, 44) may also implement bridging, routing, or filtering capabilities that inhibit transmission of an intra-network message beyond its local network (32, 34, 36).

Abstract: A downhole digital power amplifier comprises a device which, through digital means, provides a sinusoidal, variable frequency, variable power and variably phase-shift modulated output for the transmission of data from a downhole sensor arrangement to an uphole receiver. Selection and variation of frequency, power and modulation are made through digital inputs. The device provides these functions at extra low frequencies (ELF) low-to-high power output, and varying phase-shift keying.
