Title: A thermal detector array
Inventor: WATTON REX
IPC: G01J5/34
Filed: 1998-05-14
Abstract: A thermal detector device comprising an array of thermal detector elements, an array of microbridge structures comprising the array of thermal detector elements, readout silicon integrated circuitry (ROIC) and an interconnect layer on which the array of microbridge structures are arranged. The interconnect layer comprises a plurality of conducting interconnect channels providing an electrical connection between the microbridge structures and input contacts on the ROIC such that the microbridge structures are in electrical contact with, but are separated from, the readout silicon integrated circuitry. As the interconnect layer separates the microbridge structures from the ROIC, the detector material, typically a ferroelectric material, may be fabricated on the microbridge structures at a deposition or anneal temperature which is not limited by the avoidance of damage to the ROIC. Deposition temperatures of at least 500 °C or, preferably, at higher temperatures e.g. 700 °C-900 °C, may therefore be used, enabling the fabrication of high performance ferroelectric or microbolometer thermal detector arrays. The invention also relates to a method of fabricating high performance thermal detector arrays comprising an interconnect layer.

Inventor: LEHUEDE PHILIPPE
IPC: G02B6/02
Filed: 1998-07-07
Abstract: An optical component comprising one or more optical elements (35') aligned with the end(s) of one or more waveguides (25') is fabricated by a process in which, first of all, a doped silica core layer (20) is deposited on a substrate (10) (or on a buffer layer on the substrate), and subsequently a partial overclad layer (30A) typically 1-5 .mu.m thick is deposited on the core layer. The partial overclad layer and core layer are patterned and etched so as simultaneously to define the optical element(s) and the waveguide core(s). Afterwards, the overclad is completed by depositing a further overclad layer (30B). In the case of application of this fabrication method to a grating-based NBWDM device, the metallisation of the grating can precede or follow the deposition of the second overclad portion (30B). In either case, low-temperature deposition processes are required for deposition of this second overclad portion.

Patent CA-2316976-A1 (CA)
Title: Osmotic delivery system with membrane plug retention mechanism
Inventor: AYER RUPAL
IPC: A61K9/52
Filed: 1998-12-15
Abstract: An osmotic delivery system has a membrane plug retention mechanism which can also be used to control the delivery rate of a beneficial agent from the osmotic delivery system. The osmotic delivery device includes an implant capsule containing a beneficial agent and an osmotic agent. Holes are formed along a side wall of the implant capsule at an open end of the capsule. When the membrane plug is inserted into the open end of the capsule the membrane material swells into the holes in the capsule side wall creating a large frictional force which prevents expulsion of the membrane plug. A beneficial agent delivery rate of the osmotic delivery system is controllable by varying the size and number of the holes to change the amount of exposed surface area of the membrane plug. An increase in the surface area of the membrane plug exposed to the exterior environment causes a corresponding increase in the liquid permeation rate of the membrane and thus, increases the beneficial agent delivery rate.

Title: Method and apparatus for completing a wellbore
Inventor: MACKENZIE ALAN
IPC: E21B43/08
Filed: 2000-12-07
Abstract: A method and apparatus to provide a large bore hook hanger system incorporating sand exclusion at a junction in a multilateral wellbore includes the running of a lateral liner having an expandable sleeve positioned thereon to bridge a milled window from the lateral borehole to the primary borehole, expandable sleeve including a pre-machined window and a hook to hang the liner from the primary borehole. The hook further acts to center the pre-machined window in the expandable sleeve to provide access to the primary wellbore. The expandable sleeve is preferably covered on its outer surface with an elastomeric material and is outwardly concentric to an expandable packer for run-in. Once the expandable sleeve is positioned at the appropriate location in the junction, the expandable packer is inflated thus permanently deforming the expandable sleeve into contact with the open hole of the lateral borehole thereby preventing sand or gravel ingress to the primary borehole.
