Abstract: This invention provides an inventive tissue sampling probe which offers many advantages over probes available in the prior art. Unexpectedly superior results are obtained in connection with the retrieval of intact tissue specimens, because of a unique combination of cutting features, including, in particular, the employment of an electrosurgical cutting element which is extendible to permit ready severance of the distal end of the tissue specimen, without impact to surrounding tissue. Additionally, the inventive instrument is advantageously designed so that portions of the instrument which contact the patient's tissue or fluid discharge (i.e. blood) during a procedure are modular and disposable, to permit ready replacement of those portions with a new module for an ensuing procedure, without the necessity of cleaning and sterilizing the instrument. The versatility of the invention permits its use in many applications, including, for example, breast biopsies, intraoperative staging, laparoscopic surgery, and lymphadenectomy procedures.

Abstract: A four-wheel drive torque transfer mechanism splits torque from the transmission gearing section of a vehicle into a front-wheel torque and a rear-wheel torque, transmitting the front-wheel torque to the front-wheel drive shafts and the rear-wheel torque to the rear-wheel drive shafts. A central differential connected to the transmission gearing section distributes the torque from the transmission gearing section. A central differential limiting mechanism, provided between the input and output sides of the central differential, limits the rotary differential operation of the differential arrangement responsive to a control torque signal. Control gain values representing optimized turning characteristics are calculated for each of the turning conditions of the vehicle and stored in a memory. A controller for controlling the differential limiting mechanism reads the control gain values from the memory and calculates the products of detected turning conditions and the control gain values corresponding thereto. The controller further calculates the sum of the products and generates the control torque signal in accordance with that calculated sum.

Abstract: An optical device has five elements fabricated on one substrate. The first has an active waveguide structure supporting a first mode. The second has a passive waveguide supporting a second mode. The third has a passive waveguide supporting a third mode. The fourth element has a heatsink thermally coupled to the first element. The fifth element, at least partly butt-coupled to the first element, has an intermediate waveguide supporting an intermediate mode.
The effective mode area of the third mode is larger than that of the second mode;
A tapered waveguide structure in the second or fifth element facilitates efficient adiabatic transformation between the second mode and the intermediate mode.
A tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the second mode and the third mode.
No adiabatic transformation occurs between the intermediate mode and the first mode.-

Abstract: A device is made up of an active structure attached to a substrate, the active structure having a facet through which light couples between the active structure and another structure attached to the substrate; and an active region comprising a quantum well region that includes a sub-region, adjacent the facet, configured to undergo QWI in response to heat. The active structure also contains a heating element, positioned close to the facet and operable such that heat generated by the heating element raises a temperature of the sub-region of the active region near the facet high enough to activate QWI in that sub-region, in turn causing a reduction in optical absorption, without raising temperatures in any other portion of the active region enough to cause significant thermal stress at any interface between the substrate and the active structure.

Abstract: A device is described, having an active structure in an element attached to a substrate. The active structure comprises an active region that includes a quantum well region. All material layers that underlie the active structure and overlie the substrate are dielectric layers. An optical mode supported by the device in a region including the active structure is characterized by an amplitude having a peak value offset, in a direction towards the substrate, from the quantum well region.
In one form of the device, a passive structure attached to the substrate is optically coupled to the active structure.-

Abstract: A device comprises first, second and third elements fabricated on a common substrate. The first element comprises an active waveguide structure comprising: a first portion supporting a first optical mode. The second element comprises a passive waveguide structure supporting a second optical mode. The third element, at least partly butt-coupled to the second portion, comprises an intermediate waveguide structure supporting intermediate optical modes. At least part of the second element is non-linear, supporting frequency conversion. A tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the first optical mode and one intermediate optical mode. No adiabatic transformation occurs between any intermediate optical mode and the first optical mode. Mutual alignments of the elements are defined using lithographic alignment marks.

Abstract: A device comprises first, second and third elements fabricated on a common substrate. The first element comprises an active waveguide structure comprising: one portion, of effective cross-sectional area A1, supporting a first optical mode; and a second portion, butt-coupled to the first portion, of effective cross-sectional area A2>A1. The second element comprises a passive waveguide structure supporting a second optical mode. The third element, at least partly butt-coupled to the second portion, comprises an intermediate waveguide structure supporting intermediate optical modes. If the first optical mode differs from the second optical mode by more than a predetermined amount, a tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the first optical mode and one intermediate optical mode. No adiabatic transformation occurs between any intermediate optical mode and the first optical mode. Mutual alignments of the elements are defined using lithographic marks.
