A subsea data collection and communication system is installed at a subsea interconnect point or subsea connector used for communication between subsea electrical, optical or hybrid electro-optical cables. The data collection and communication system is configured to collect system performance data such as voltage, current, optical pressure and the like from signals carried by the wires or fibers in cables connected to the connector unit, and may also collect data on environmental conditions from sensors installed in or on the connector unit, such as temperature, pressure, or sea water salinity sensors, and the like. The collected data is transmitted to a remote monitoring station or local hub for further processing to detect potential faults or performance degradation either at periodic intervals or on demand, using bi-directional Ethernet, CANBUS, a carrier frequency system over the cable power lines, optical signal over optical fiber, or wireless communication links over short distances.

A penetrator device has an outer housing of non-conductive, insulating material having a through bore, at least one conductive pin formed in one or two parts extending through the housing and having a first end portion and a second end portion extending out of the respective first and second ends of the housing, a first cladding layer bonded over the first end portion of the pin to form a first bonded assembly, a second cladding layer bonded over the second end portion of the pin to form a second bonded assembly, and the material of the first and second cladding layer comprising a corrosion resistant conductive material different from the pin material.

A modular subsea equipment assembly including a modular base frame and a plurality of modular superstructure devices for selective attachment to the modular base frame for supporting various components and for attachment to underwater cables. The modular base frame includes a frame member forming an outer periphery of the base frame, and a plurality of cross bars extending between opposite portions of the frame member in one or more directions, the frame member and cross bars having at least upper surfaces each having a plurality of connection points for attaching selected modular devices of the assembly to the base frame in a plurality of different possible configurations.

An electroplating system and method has a needle anode associated with an XYZ or multi-direction positioning device and is configured for plating internal surfaces of holes in metal products. The needle anode is positioned such that an insertion portion of the needle anode is centered over a hole and inserted to a predetermined depth in the hole, with a discharge end located a predetermined distance from the inner end of the hole. Plating solution is supplied to the needle anode and flows continuously during plating from the discharge end of the needle, through a gap between the needle anode and inner surface of the hole, and out of the open end of the hole into a drain. In one example, the metal object is a terminal of an electrical connector and the hole is a solder cup at a terminal end of the connector.

A radio or telephone handset configured with the usual transmitter and receiver ends and connecting handle is designed to have physical characteristics well adapted in its acoustic characteristics to complement noise cancellation circuitry. The receiver speaker is mounted in the receiver cap, and the cap is built with a domed, apertured earpiece extending from the exterior surface of said receiver cap. The dome fits into a user's outer ear, thereby to aid in positioning said handset on a user's ear. Openings radially placed on said receiver cap exterior surface and surrounding said earpiece, define an acoustic grill through which signal from said receiver speaker is passed substantially directly to said user's ear canal. Noise absorbing material is placed at strategic locations within the handset interior.

Noise-cancelling telephone handset

Telephone headsets used by operators and airline pilot headsets are subject to substantial amounts of interfering ambient noise which detract from the intelligibility of incoming speech. Noise reduction circuitry does not altogether eliminate the interfering sound. A headset speaker and error microphone housing are disclosed which enable a greater amount of unwanted noise elimination. The speaker and microphone are configured closely with respect to each other and also to the user's ear. They are acoustically isolated in their own chamber. The microphone is located approximately on the speaker axis and protrudes substantially into the user's ear; and also is disposed close to the speaker cone surface. Additional acoustical tuning features include venting ports in the housing, and acoustic damping padding at the microphone entrance and on either side of the speaker. These expedients enhance the ability of the noise-cancelling circuitry to effectively reduce the undesired noise heard by the user.
