Filed:

Dec 4, 2001

Appl. No.:

10/007689

Inventors:

Ellen M. Gately - Merrimack NH
Robert A. McGrath - Londonderry NH
Mark W. Gailus - Somerville MA

Assignee:

Teradyhe, Inc. - Boston MA

International Classification:

H01R 909

US Classification:

174266, 174262, 174258, 257698, 361795

Abstract:

A multi-layer printed circuit board includes a via having a conductive upper portion, a conductive lower portion, and an electrically insulating intermediate portion between the upper and lower portions. In one embodiment, the insulating intermediate portion of the via is provided by a non-platable layer of the circuit board, as may be comprised of PTFE. Vias having a continuous conductive coating may be formed through clearance holes in the non-platable layer which are provided with a platable inner surface, either by filling the hole with a platable material, such as epoxy resin, prior to laminating the board or by chemically conditioning the non-platable material to make it platable. In a further embodiment, the as insulating intermediate portion of the via has a narrower diameter than the conductive upper and lower portions.

US Classification:

Abstract:

An image sensing device comprising active pixels is disclosed, each pixel having a charge accumulation region for collecting charges generated by a photosensitive element such as a photodiode. A linear voltage to current converter, current mirrors, and a differential amplifier generate an output signal and minimize fixed pattern noise and improve the signal to noise ratio. Image quality is improved by reducing pixel blooming and image smearing through an improved method for resetting the pixels with a bias voltage reference which is less than Vdd. Active circuitry and physical device layout reduce the effects of IR voltage drops along the bus lines in a massive pixel array.

Appl. No.:

5/610565

Inventors:

Robert L. McGrath - East Pepperell MA

International Classification:

F16K 2300

US Classification:

137312

Abstract:

A service connection between a water main and a meter within a building has a service conduit within a leakage conduit. The leakage conduit has a sealed connection with a casing sealed to the main and enclosing a corporation stop to which the service conduit is connected. The leakage conduit is sealed to the service conduit within the building and adjacent the meter and includes an outlet extending outwardly through the building wall above the ground so that leakage within the corporation casing or a leak in the service conduit may be quickly detected. In the event of a leak, the service conduit may be removed and replaced through the leakage conduit with excavation limited to exposing the corporation casing and the end of the leakage conduit connected thereto. A snake provided with a flexible wedge that includes connections with an existing service conduit and a leakage conduit to be installed enables the former to be withdrawn and the latter simultaneously to be pulled through the ground to effect its installation. The flexible wedge may be double ended with a cable connected to each end.

Appl. No.:

9/028072

Inventors:

Robert Daniel McGrath - Andover MA

Assignee:

Polaroid Corporation - Cambridge MA

International Classification:

H01L 2972

US Classification:

257445

Abstract:

An improved pixel design for a CMOS image sensor with a small feature size is described. In conventional image sensors of this type, the quantum efficiency is typically reduced as a result of the decreased thickness of the top n-type layer of the photodiode and the presence of an intervening p-type layer which is higher doped than the substrate. In the pixel design of the invention, the higher doped p-type layer underneath the photodiode is omitted while barrier regions channel the carriers generated by the impinging radiation towards the top n-layer of the photodiode. A high quantum efficiency is thereby attained in spite of a shrinking feature size. The novel pixel design can also incorporate anti-blooming protection.
