The shaft may also include a moisture sensor disposed within the outer sheath of the shaft and configured to detect moisture within the outer sheath. The shaft may include couplings that connect a distal end of the outer sheath to a surgical attachment and a proximal end of the outer sheath to a remote power console.

Systems and methods are disclosed for using 802.11 based wireless protocols in various energy management applications wherein a host controller uses various types of communication networks to distribute information to an on-premise processor that in turn uses 802.11 based wireless protocols to communicate with various types of end devices, such as utility meters. Various forms of communication are defined between the end device, the on-premise processor, and the energy management host for accomplishing power load control, including determining when to activate or deactivate a load, requesting permission to activate a load, reading usage data, activating or deactivating a meter, and determining rate schedules. A flexible scheme allows control to be shifted to be resident in various entities. The architecture is applicable not only for power load control, but other control type and metering devices.

A wireless charging and power system for electronic devices and method for communicating power to a power receiver employing wireless energy transmission are disclosed. The remote charging system includes a power transmission unit, which transmits energy as a plurality of constructive transmitted frequencies, and a power receiver system that receives the transmitted frequencies. The power receiver system is preferably incorporated in a device and includes an energy receptor capable of receiving the wireless transmitted energy and transferring the energy from the transmitted frequencies to an energy storage device included in the device. The power transmission unit receives and tracks a power request signal from the power receiver system to track the power receiver system location during energy transmission. Data streams may be incorporated into the wireless signals of the remote charging system, allowing the remote charging system to function as a communications pathway as well as a power delivery system.

A system for accomplishing bi-directional digital audio data and control communications. There is a host end that includes a host transceiver, a host digital signal processor that outputs a master clock signal and audio data, and a source of low-voltage power for the host components. There are a number of remote nodes connected together serially. Each remote node includes a transceiver and a low-voltage power supply that provides power to the other remote node components. A shielded two-wire communication network connects the host node to one of the remote nodes, and connects each remote node to either one or two other remote nodes in a daisy-chain configuration. The host end is enabled to transmit and receive over the communication network digital audio data and digital control signals. The remote nodes are each enabled to receive over the communication network digital audio data and digital control signals, and are each enabled to transmit over the communication network digital control signals. The source of low-voltage power at the host end is coupled to the communication network. The remote power supplies each have an input coupled to the communication network to derive the power for the remote nodes from the power coupled to the network by the host end.

A hydraulic fracturing system for fracturing a subterranean formation includes a power generation system, a transmission section, and an equipment load section. The power generation system includes a turbine generator that generates electricity that is used to power equipment in the equipment load section. The equipment in the equipment load section conditions and pressurizes fluid that is injected into a wellbore for fracturing the formation. The power generation and equipment load sections are distal from one another are separated by a long distance. The transmission section connects the power generation and equipment load sections, and thus spans the long distance between these sections.

A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit. This invention also features a display that is both powered and controlled using radio frequencies. It describes a complete system for controlling, addressing, and powering a display. The system includes an antenna or antennae, passive charging circuitry, and active control system, a display, and an energy storage unit. There is also a separate transmitter that provides the remote power for the display. The system is meant to be used anywhere it is useful to provide intermittent updates of information such as in a store, on a highway, or in an airport. A tile-based display allowing a modular system for large area display is created using a printable display material.

An apparatus, system and method in an electrical system using power system information or data associated therewith having a time component associated therewith sampled or obtained from the electrical system at a local and a remote location, wherein the local and remote data are time aligned and used to provide control, monitoring, metering, and / or automation to the electrical system. The local IED may be adapted to receive power system data from the remote IED, time align the local and remote synchronized power system data, and perform math operations on the local and remote power system data.

A wire feeder including a motor driving a set of feed rolls to force a welding wire from a spool through a welding torch to a welding operation. The wire feeder has an input lead to be connected to the output terminal of a remotely located power source having an on condition and an off condition where a welding current is directed to the output terminal only when the source is in the on condition. A weld starting trigger with a weld start position located adjacent the torch closes a switch when the trigger is shifted to the weld position, a circuit senses when the switch is closed, and a transmitter on the wire feeder transmits a start signal to the power source when the trigger switch is closed whereby the power source is shifted to its on condition when the trigger is in the weld position.

A vertical-mount network remote power management outlet strip embodiment of the present invention comprises a long, thin outlet strip body with several independently controllable power outlet sockets distributed along its length. A power input cord is provided at one end, and this supplies AC-operating power to relays associated with each of the power outlet sockets. The relays are each addressably controlled by a microprocessor connected to an internal I2C-bus serial communications channel. The power-on status of each relay output to the power outlet sockets is sensed and communicated back on the internal I2C-bus. A device-networking communications processor with an embedded operating system translates messages, status, and controls between the internal I2C-bus and an Ethernet port, and other external networks.
