Abstract: According to an embodiment, a holographic microscope comprises a light source, an optical system splitting light emitted from the light source into an object and a reflective mirror and inducing interference between light reflected by the object or transmitted through the object and light reflected by the reflective mirror, a first image sensor receiving the interference light and sensing interference information for the interference light, a second image sensor receiving the light reflected by the object or transmitted through the object and sensing information for the received light, and an image processor deriving a shape of the object based on the interference information sensed by the first image sensor and the information sensed by the second image sensor.

Abstract: Disclosure relates to an electrochemical membrane degassing apparatus including a liquid channel in which raw water flows, a gaseous channel in which gas degassed from the raw water flows, a gas separation membrane allowing gas in the raw water to be moved to the gaseous channel, a surface modification layer formed at the gas separation membrane, and a power supply unit applying power to the surface modification layer, and selectively operated in either of a first process mode applying a low voltage power and a second process mode applying a high voltage power, wherein in the first process mode, an electrostatic repulsive force is generated between the surface modification layer and organic particles, and in the second process mode, a radical is generated, and the organic particles is oxidized by the radical. Accordingly, the efficiency of membrane degassing can be improved and membrane contamination can be prevented.

Abstract: The present disclosure includes a device for retrieving foreign material within a blood vessel of a patient. Some foreign retrieval devices include an elongated body configured to be disposed within a catheter, the elongated body having a proximal end, and a distal end opposite the proximal end; and one or more arms, each arm having a proximal end coupled to the distal end of the elongated body, and a distal end extending toward the proximal end of the elongated body. In some foreign retrieval devices, each of the arms is configured to be actuated from a closed position to an open position.

Abstract: This disclosure includes embodiments of mallets with radiolucent heads to permit radiologic imaging of a device (e.g., needle) as the device is being positioned with the mallet, as well as methods of using such a mallet, and methods of imaging a device while it is being positioned with such a mallet.

Abstract: The present invention relates generally to a system and methods for providing protective coverage of an operational surface and any items that may be on the surface. Certain embodiments of the system may be used to help to maintain the sterility of a surface and the items on the surface. Advantageously, such embodiments of the system may be used to maintain the sterility of surgical instruments and materials, and the table surface on which they are placed prior to the start of the surgical procedure. Other embodiments of the system may be used to at least help to prevent the contamination of or maintain the freshness of food and the containers and utensils used to hold, prepare, and serve the food.
