    摘要： An endoscope includes a rigid section having an opening situated between two ends. The endoscope also includes a handle for manipulation and at the first end. An image capturing device is near the second end and is configured to provide a first view when pointed in a first direction. The image capturing device is moved with respect to a longitudinal axis of the rigid section in response to a movement of an extension portion of a shaft located in the opening and operatively coupling the handle and a first base part resulting from the manipulation of the handle. A fixing member is rigidly coupled to the rigid section and pivotably coupled to the first base part at a second pivot portion of the first base part, and a second base part is pivotably connected to the fixing member at a pivot portion of the second base part.

    摘要： An endoscope including a rigid section having opposed first and second ends and an opening situated between the first and second ends, the rigid section defining a longitudinal axis; a handle portion coupled to a first end of the rigid section and having first and second scissor-type handles suitable for grasping by a user; and a base part situated at the second end of the rigid section and coupled to the first handle of the scissor-type handles such that displacement of the first handle causes a rotation of the base part.

    摘要： A photodetector, detector array, and method of operation thereof in which nanojunctions are formed by crossing layers of nanowires. The crossing nanowires are separated by a few nm thick electrical barrier layer which allows tunneling. Each nanojunction is coupled to a slot antenna for efficient and frequency-selective coupling to photo signals. The nanojunctions formed at the intersection of the crossing wires defines a vertical tunneling diode that rectifies the AC signal from a coupled antenna and generates a DC signal suitable for reforming a video image. The nanojunction sensor allows multi/hyper spectral imaging of radiation within a spectral band ranging from terahertz to visible light, and including infrared (IR) radiation. This new detection approach also offers unprecedented speed, sensitivity and fidelity at room temperature.
