摘要： Two discrete transmit/receive (T/R) channels are implemented in a single common T/R module package having the capability of providing combined functions, control and power conditioning while utilizing a single multi-cavity, multi-layer substrate comprised of high temperature cofired ceramic (HTCC) layers. The ceramic layers have outer surfaces including respective metallization patterns of ground planes and stripline conductors as well as feedthroughs or vertical vias formed therein for providing three dimensional routing of both shielded RF and DC power and logic control signals so as to configure, among other things, a pair of RF manifold signal couplers which are embedded in the substrate and which transition to a multi-pin blind mate press-on RF connector assembly at the front end of the package. DC and logic input/output control signals are connected to a plurality of active circuit components including application specific integrated circuits (ASICs) and monolithic microwave integrated circuit chips (MMICs) via spring contact pads at the rear of the package. The MMICs which generate substantially all of the heat are located in multi-level cavities formed in the substrate and are bonded directly to a generally flat a heat sink plate which is secured to the bottom of the substrate and acts as a thermal interface to an external heat exchanger such as a cold plate. DC power conditioning is also provided by a capacitive bank type of energy storage subassembly externally attached to the rear of the module package for supplying supplementary power to the module during peak power operation. The T/R module is one module of an array of like T/R modules coupled to an active aperture of a radar system.

摘要： A transmit/receive (T/R) module adapted for use in a radar system. The module has a unified structure including a layered substrate on and in which two T/R channel circuits are integrated. The channel circuits make use of power distribution, channel controller, and RF signal routing circuitry, partly on a channel shared basis. In the RF routing circuitry, respective coupler elements are employed to combine RF receive signals for output to an RF receive manifold and to split an RF transmit signal from a transmit manifold into separate RF transmit signals for input to the T/R channel circuits.

摘要： Two discrete transmit/receive (T/R) channels are implemented in a single common T/R module package having the capability of providing combined functions, control and power conditioning while utilizing a single multi-cavity, multi-layer substrate comprised of high or low temperature cofired ceramic layers. The ceramic layers have outer surfaces including respective metallization patterns of ground planes and stripline conductors as well as feedthroughs or vertical vias formed therein for providing three dimensional routing of both shielded RF and DC power and logic control signals so as to configure, among other things, a pair of RF manifold signal couplers which are embedded in the substrate and which transition to a multi-pin blind mate press-on RF connector assembly at the front end of the package. DC and logic input/output control signals are connected to a plurality of active circuit components including application specific integrated circuits (ASICs) and monolithic microwave integrated circuit chips (MMICs) via spring contact pads at the rear of the package. An RF connector assembly for coupling transmit and receive signals to and from the module is located at the front of the package. The RF transmit power amplifiers which generate most of the heat in the module package are located in a first pair of cavities formed in the substrate directly behind the RF connector assembly and are mounted directly on a pair of flat heat sink plates which are secured to the bottom of the substrate and acts as a thermal interface to an external heat exchanger such as a cold plate. A second pair of cavities in which are located the RF receive signal amplifiers and their respective receiver protector elements, is located beside the first pair of cavities directly behind the RF connector for reducing RF signal loss.

摘要： An approach to rejecting input common-mode voltage variations in a sampler/converter that avoids the use of a differential amplifier in the signal path, and without introducing added distortion or noise. In one embodiment, the input common-mode variations are sensed on a pair of matched resistors that straddle the common mode analog inputs, on a node ‘Vcmi’. An alternative, switched-capacitor-based sensing scheme is also possible. Using this measured Vcmi, adjustments are then made to the rest of the sampler/converter to take out any variations observed at Vcmi.

摘要： A dual action biopsy needle scrapes tissue of cellular thickness from a lesion during forward and rearward reciprocations of the needle along its longitudinal axis of symmetry. A first sharp edge, formed by a beveled distal end of the needle, scrapes tissue during proximal-to-distal travel of the needle. A second sharp edge is provided by a transversely disposed slot formed in the needle near the first sharp edge. The second sharp edge scrapes tissue during distal-to-proximal travel of the needle. In a first embodiment, the second sharp edge is coincident with an exterior surface of the needle. In a second embodiment, the second sharp edge is elevated with respect to the exterior surface and in a third embodiment the second sharp edge is recessed. Additional embodiments include a second slot, a channel, and a hinge for enabling pivotal movement of the second and third sharp edges.

摘要： A balloon angioplasty apparatus includes a guide wire, a balloon catheter, and a guide catheter. The balloon catheter has slots formed in it to define a plurality of elongate members between the slots. A joint is formed at the proximal, distal, and mid-point of each elongate member. Displacing the proximal and distal joints toward one another causes the respective middle joints to displace radially outwardly, and radial inward travel of the middle joints is caused by increasing the distance between the proximal and distal joints. A mesh that captures emboli overlies the jointed members and opens and closes with them. The guide catheter is used to close the joined members and the emboli-capturing mesh at the conclusion of the angioplasty procedure. In a second embodiment, the jointed members are formed in a delivery catheter. In a third embodiment, the jointed members are formed in a guide wire.

摘要： A bioabsorbable marker is placed in soft tissue such as breast tissue near a lesion during a biopsy procedure. If tests prove the lesion to be malignant, the marker indicates the location of the lesion and the marker is removed surgically together with the lesion. If tests prove the lesion to be benign, there is no need to surgically remove the marker due to its bioabsorbability. One or more markers may be carried in an elongate, flexible marker carrier that is ensheathed within an elongate, flexible outer sheath. The flexible outer sheath is slidingly introduced into the proximal end of a biopsy needle until its distal free end protrudes from a port formed in the distal end of the biopsy needle. Retraction of the outer sheath relative to the marker carrier then exposes the marker carrier. The markers exit the marker carrier under their own inherent bias or an auxiliary bias is employed to eject them from the marker carrier. In a first embodiment, the bioabsorbable markers are hollow spheres made of polylactite acid. They are filled with iodine or other radiopaque material so that they are visible under X-rays and/or ultrasound. The radiopaque material is also bioabsorbable. In an additional embodiment, the hollow spheres are filled with an easily visible dye so that, when punctured, they provide a visible indication of a lesion's location. In another embodiment, they are filled with radioactive material and are inserted for therapeutic purposes in a lesion known to be malignant. Another embodiment provides solid markers, formed by pre-mixing together a radiopaque material and a bioabsorbable material. The solid markers may also include dyes and radioactive materials. In all embodiments, the markers may be spherical, cubical, pyramidal, pentagonal, or any other predetermined shape.
摘要翻译：在活组织检查过程中，将生物可吸收标记置于软组织如乳腺组织附近的病变处。如果测试证明病变是恶性的，则标记表示病变的位置，并且与病变一起手术除去标记。如果测试证明病变是良性的，则由于其生物吸收性，不需要手术除去标记物。一个或多个标记可以被携带在细长的，柔性的标记载体中，所述标记载体在细长的柔性外鞘内接合。柔性外鞘被滑动地引入活检针的近端，直到其远端自由端从形成在活检针的远端的端口突出。外鞘相对于标记载体的缩回然后露出标记物载体。标记在它们自己的固有偏压下离开标记载体，或者使用辅助偏压将其从标记载体中排出。在第一实施方案中，生物可吸收标记物是由聚乳酸制成的中空球体。它们被碘或其他不透射线的材料填充，使得它们在X射线和/或超声下是可见的。不透射线的材料也是生物可吸收的。在另外的实施方案中，中空球填充有容易看到的染料，使得当被刺穿时，它们提供病变位置的可见指示。在另一个实施方案中，它们用放射性物质填充，并且在已知为恶性的病变中插入用于治疗目的。另一个实施方案提供通过将不透射线材料和生物可吸收材料预混合在一起形成的固体标记物。固体标记物还可以包括染料和放射性物质。在所有实施方案中，标记可以是球形，立方体，金字塔形，五边形或任何其它预定形状。
