Title: Optical interleavers/deinterleavers
Inventor: CHANG KOK-WAI
IPC: G02B27/10
Filed: 2001-10-22
Granted: 2009-10-06
Abstract: Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. When operating as a deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g. WDM signal) into subsets of optical signals (e.g. channels). In one embodiment, deinterleaving optical signals separates an optical signal into even and odd International Telecommunications Union (ITU) channels. The interleaver/deinterleavers may include isolator components to route optical signals to and from input/output ports. A variety of reflective elements, e.g. quarter wave mirrors, reflective prisms, etalons, can be used for double passing the signals through a birefringent crystal assembly.

Granted: 2011-05-03
Abstract: This invention is a validation protocol for determining whether an untrusted authentication chip is valid, or not. In another aspect it concerns a validation system for the protocol. The protocol may be used to determine the physical presence of a valid authentication chip. In this case a system may call the trusted chip to generate a random number and a digital signature for it, encrypt them with a first key and then call a prove function in the untrusted chip. The prove function decrypts the random number and signature, and calculates another signature from the decrypted random number, for comparison with the decrypted one. If the comparison is successful the random number is encrypted with another key and sent back. Finally, a test function is called in the trusted chip to generate its own encrypted version of the random number using the second key and then compare it with the received version to validate the untrusted chip. The untrusted chip may be associated with a consumable so that validation of the untrusted chip authenticates the consumable.

Title: System, method and apparatus for deploying a data resource within a threaded pipe coupling
Inventor: MORRISH MARTIN MELVILLE
IPC: F16L15/00
Filed: 2001-09-28
Granted: 2009-09-08
Abstract: A data resource (22) specific to a pipe coupling (18) centrally positioned within the coupling (18), intermediate the coupling ends. Multiple couplings (18) are employed to connect together a string of well pipe (p). The data resource (22) is adapted to be deployed at the coupling center (J) in the space formed between the abutting ends of pipe (p) made up into the coupling (18). The data resource (22) provides information regarding the physical characteristics and locations of the coupling (18), the attached string pipe (p) or the environment within which the coupling (18) is disposed. The data resource (22) may be a read-only component or it may be a readable and writeable component. The resource (22) communicates with an instrument (I) movable through the pipe (p) and coupling (18). The data resource (22) may b e removably positioned at the center of the coupling (18) or it may be permanently cemented in place. The data resource (22) may take on the form o f an annular ring (10) with a crushable structure (26) and suitable recesses (21) for holding a data source (22) module. A circular communication antenna (23) may be carried in the ring (10). A preferred form of the data resource (22) is an externally threaded Teflon ring (10) equipped with axially extending resilient fingers (26). Theresilient fingers (26) are deformable upon engagement with the rotating ends of the pipe (p) sections so that advancing the pipe (p) sections beyond their optimum depth into the coupling (18) deforms the fingers (26) without rotating and thus displacing the ring (10). The body (25) of the ring (10) remains in the gap between the pipe (p) and where it is protected from crushing.

Title: Quick change powder coating spray system
Inventor: SCHROEDER JOSEPH G
IPC: B05B14/45
Filed: 2001-11-09
Granted: 2010-01-05
Abstract: Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns (20) inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator (42). The powder falls into a transfer pan (314) and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver (320). The powder is then discharged to the feed hopper (310) in the feed center (46). The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line (318) cleaned by one or more cleaning elements drawn through the vacuum line.

IPC: B01D46/24
Filed: 2002-04-23
Granted: 2010-07-20
Abstract: A ceramic honeycomb wall-flow filter is prepared by plugging channels in a ceramic honeycomb comprised of clay by a method comprising the following. First, a mixture comprised of a dispersing liquid and ceramic powder is formed. Second, the mixture is inserted into at least one channel of a green ceramic honeycomb that is comprised of a clay to form a plugged green ceramic honeycomb wherein the dispersing liquid essentially fails to swell the clay. Alternatively, the mixture is inserted into a calcined ceramic honeycomb to form a plugged calcined ceramic honeycomb. Finally, the plugged green or calcined ceramic honeycomb is heated to a temperature sufficient to sinter the plugged green ceramic honeycomb to form a porous sintered plugged ceramic honeycomb. The method is particularly useful for simultaneously making the plugs and discriminating layers in the channels. In particular the method is useful to make wall-flow filter having plugs on at least one end with same composition as the discriminating layer or plugs on each end having different compositions.
