A physiological measurement system can include a low noise patient cable that connects a monitor and a noninvasive optical sensor. The cable has a plurality of emitter wires configured to communicate a drive signal between the monitor and at least one emitter. The cable also has a plurality of detector wires configured to communicate a physiological signal between at least one detector responsive to the emitter and the monitor. The emitter and detector wires are orthogonally disposed so that crosstalk between the two functionally different wires is mitigated.

An automated assembly sensor cable has a generally wide and flat elongated body and a registration feature generally traversing the length of the body so as to identify the relative locations of conductors within the body. This cable configuration facilitates the automated attachment of the cable to an optical sensor circuit and corresponding connector. In various embodiments, the automated assembly sensor cable has a conductor set of insulated wires, a conductive inner jacket generally surrounding the conductor set, an outer jacket generally surrounding the inner jacket and a registration feature disposed along the surface of the outer jacket and a conductive drain line is embedded within the inner jacket. A strength member may be embedded within the inner jacket.

The present invention includes a high performance communications cable for transmission media that includes core support-separators which define clearance channels to maintain spacing between transmission media or transmission media pairs. The core support-separator can be either interior to a cable jacket or be employed singularly without the benefit of a jacket and extends along the longitudinal length of the communications cable. The core support-separator has a central region that may include flap-tops along the radial edge that are available for partial or complete sealing of the clearance channels during manufacturing operations. The central region may also include a hollow center portion and include various geometric shapes to provide proper spacing between conductors. Each of the defined clearance channels allow for disposal therein of metal conductors and/or optical fibers.

The invention discloses a water-blocking medium voltage aluminum alloy power cable which comprises an insulating cable core and an outer wrapping layer, wherein one or more insulating cable cores are provided; the insulating cable core is wrapped by the outer wrapping layer so as to form the water-blocking medium voltage aluminum alloy power cable. The cable is characterized in that each insulating cable core comprises an inner aluminum alloy conductor core (1), an inner shielding layer (2), an insulating layer (3), an outer shielding layer (4), a semiconductor resistor water-blocking zone (5) and a seamless metal sleeve (6) from inside to outside in sequence; the outer wrapping layer comprises a winding and wrapping layer (7), an inner protective layer (8), an armored layer (9) and an outer protective layer (10) from inside to outside The aluminum alloy power cable disclosed by the invention is made of an aluminum alloy material, the inner aluminum alloy conductor core is high in yield strength, small in resilience value, free of memory effect and easy to install, and compared with a copper core cable of the same mass, the cable is small in resistance, and the cost of the alloy material is smaller than that of copper.

In a wireless IC tag, metallic antennas are deposited as thin films on the front and back surfaces of a spacer, made of a heat-resistant glass epoxy material having a desired dielectric constant, to form a first antenna and a second antenna. An IC chip is mounted in the center of the first antenna. The second antenna functions as an auxiliary antenna for resonating to a desired frequency of a transmission radio wave of the first antenna to strengthen the intensity of the radio wave. Accordingly, even when the IC tag is mounted to a cable or the like, the tag can be mounted in the interior of the enclosure of the cable and thus the radio wave intensity of the first antenna can be prevented from being weakened by a metallic member in the cable.

A cable assembly for attachment to an entry port of an optical enclosure. The assembly includes a plug for an end of an optical cable in a sealed housing having a single rigid tube and a single sealed nut. Connectorized optical fibers or an optical ribbon extend from the plug into the equipment enclosure.

A cooling system for an electronic equipment enclosure employs a flat plate heat pipe to deliver heat from the interior of the enclosure through a connector to a removable external heat sink. The heat pipe includes a metallic bottom plate having a depression therein containing a set of rods evenly spaced from one another. A top plate covers the bottom plate with the rods compressed therebetween. Channels formed between adjacent rods are partially evacuated and injected with an evaporative fluid. The fluid and its vapor circulate in the channels to convey heat from a warm end of the heat pipe to a cool end. The heat sink is of similar construction.

A connector apparatus for controlling fluid dispensing/transmission that includes a control component for communication between couplers thereof. A first coupler has a transmitter, and is releasably connected with a mating reader coupler that has a transmitter and fluid control device to exchange information with the transmitter of the first coupler. The transmitters communicate and are operated by wireless means such as by RF devices. Upon confirming that the first coupler is properly coupled to the mating coupler and that the first coupler has a proper identification, the fluid control device controls fluid flow, using the transmitters of the first coupler and the mating reader coupler, under predetermined parameters, e.g., pressure, temperature, duration, and flow rate, as indicated in the first coupler.

A fabric including within its construction a first elongated electrical conductor crossed by a second elongated electrical conductor, the conductors being normally biased apart at a crossover point of said fibres with an air gap between them, whereby application of pressure in a direction substantially normal to a plane of the fabric causes the conductors to make contact. The fabric may be woven, knitted, non-woven or plaited. The fabric can be used as a pressure sensor, switch or other sensor.

A cable wherein even when there is a substantial volume of cable identifying information for identifying the cable, all of that cable identifying information can be simply and speedily written-in. This cable has a cable core, an integrated member with a chain of RFIDs including a plurality of RFID elements arranged at suitable intervals along a longitudinal direction of the cable core, to and from which cable identifying information can be written-in and read-out by transmission of electromagnetic energy, and a transmission coaxial cable for collectively writing-in cable identifying information to all of the RFID elements.

A spoolable composite tube capable of being spooled onto a reel for storage and for use in oil field applications. The spoolable tube exhibits unique anistropic characteristics that provide improved burst and collapse pressures, increased tensile strength, compression strength, and load carrying capacity, while still remaining sufficiently bendable to be spooled onto a reel in an open bore configuration. The spoolable composite tube can include an inner liner, an interface layer, fiber composite layers, a pressure barrier layer, and an outer protective layer. The fiber composite layers can have a unique triaxial braid structure.
