Abstract: An endoscopic system includes an integrated grasper device passing through a device lumen in the cannula. The grasper device has distal end forming two jaw portions that are biased to remain in an open position if unconstrained. The grasper has arch shaped portions that push against the inner surface of the device lumen when the grasper is retracted. To close the jaws of the grasper the grasper is retracted proximally until the arch shaped portions engage the opening of the device lumen. Further retraction causes the grasper jaws to close through engagement with the device lumen inner surface. The endoscopy system can include a single-use, removable cannula having a camera module on its distal tip. A re-usable portion can include the hand piece and display screen.

Abstract: Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as pillars and/or holes, effectively increase the effective absorption length resulting in a greater absorption of the photons. Using microstructures for absorption enhancement for silicon photodiodes and silicon avalanche photodiodes can result in bandwidths in excess of 10 Gb/s at photons with wavelengths of 850 nm, and with quantum efficiencies of approximately 90% or more.

The display unit and the handle include respective mechanical connectors that engage each other to removably mount the display unit on the handle by sliding motion relative to each other, and the display unit is removable tool-free from said handle for disposal of the handle and cannula after a medical procedure therewith.

Abstract: Microstructures of micro and/or nano holes on one or more surfaces enhance photodetector optical sensitivity. Arrangements such as a CMOS Image Sensor (CIS) as an imaging LIDAR using a high speed photodetector array wafer of Si, Ge, a Ge alloy on SI and/or Si on Ge on Si, and a wafer of CMOS Logic Processor (CLP) ib Si fi signal amplification, processing and/or transmission can be stacked for electrical interaction. The wafers can be fabricated separately and then stacked or can be regions of the same monolithic chip. The image can be a time-of-flight image. Bayer arrays can be enhanced with microstructure holes. Pixels can be photodiodes, avalanche photodiodes, single photon avalanche photodiodes and phototransistors on the same array and can be Ge or Si pixels. The array can be of high speed photodetectors with data rates of 56 Gigabits per second, Gbps, or more per photodetector.

Abstract: Resistive RAM (RRAM) devices having increased reliability and related manufacturing methods are described in combination with stacked technology with CMOS ASIC wafters. Greater reliability of RRAM cells over time can be achieved by avoiding direct contact of metal electrodes with the device switching layer. Stacking technology can be used to address incompatibility of ReRAM processing and CMOS ASICs processing.

Abstract: An endoscope in which a reusable portion is inserted nearly all the way into a hollow, pistol-grip handle of a single-use portion and the protruding part of the reusable portion and an adjacent part of the handle are covered with a flexible and resilient cap. The same cap covers the open end of the handle when the single-use portion is shipped from a manufacturing site. At a user's facility, a health professional tears the pouch, removes the cap from the handle, inserts the reusable portion, and covers the distal end of the reusable portion and an adjacent part of the handle with the same cap. Typically, a remote display connects to the endoscope wirelessly or through a cable, with a connector that fits through a hole in the cap configured to keep fluids from entering around the connector. The wireless transmission preferably uses a proprietary protocol to preserve medical data confidentiality.

Abstract: Lateral and vertical microstructure enhanced photodetectors and avalanche photodetectors are monolithically integrated with CMOS/BiCMOS ASICs and can also be integrated with laser devices using fluidic assembly techniques. Photodetectors can be configured in a vertical PIN arrangement or lateral metal-semiconductor-metal arrangement where electrodes are in an inter-digitated pattern. Microstructures, such as holes and protrusions, can improve quantum efficiency in silicon, germanium and III-V materials and can also reduce avalanche voltages for avalanche photodiodes. Applications include optical communications within and between datacenters, telecommunications, LIDAR, and free space data communication.

Abstract: A handheld endoscope has a disposable, single-use portion that includes a fluid hub, cannula, distal tip and is steerable by the operator though actuation of one or two levers. The endoscope also includes multiple-use portion that has a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module that is rotatable to allow viewing by the operator and others. The single-use and multiple-use portions mate and un-mate with each other via physically separated mechanical and electrical connectors. The component of the endoscope can be supplied to users in different combinations of pre-assembled configurations, some in a sterile package. The single use portion can include grasper device that can be actuated by an operator using an actuation tab.

Abstract: A method and system acquiring, processing and displaying breast ultrasound images in a way that makes breast ultrasound screening more practical and thus more widely used, and reduces the occurrence of missing cancers in screening and diagnosis, using automated scanning of chestwardly compressed breasts with ultrasound. Enhanced, whole-breast navigator overview images are produced from scanning breasts with ultrasound that emphasize abnormalities in the breast while excluding obscuring influences of non-breast structures, particularly those external to the breast such as ribs and chest wall, and differentiating between likely malignant and likely benign abnormalities and otherwise enhancing the navigator overview image and other images, thereby reducing the time to read, screen, and/or diagnose to practical time limits and also reduce screening or diagnostic errors.
