Title: Dynamic Raman signal acquisition system, method and apparatus
Inventor: KRESMIR FRANJIC
IPC: G01N21/65
Filed: 2019-08-08
Abstract: A Raman system 1500 for analysing biological tissue includes a Raman probe 1502 connected to a laser 1504. A sample 1510 is excited for a designated acquisition time at a designated irradiation power and the response analysed by a spectrometer 1508. A controller 1506 processes the response signal and compares its amplitude with a threshold. When the amplitude exceeds the threshold the computer 1506 lowers the irradiation power of the laser 1502 and repeats the process for a subsequent signal. The acquisition time may be dynamically increased if the Raman response signal is below the threshold. The system 1500 may be a handheld device for use during surgery. The system 1500 may also generate background signals which are used to correct the raw response signals from background for example due to ambient light. A light detector 1518 and directional coupler 1516 may identify good optical contact between the sample 1510 and the probe 1502.

Title: Cross-domain metric learning system and method
Inventor: LIU REN
IPC: G06N20/00
Filed: 2020-07-27
Abstract: An augmented reality (AR) system includes: convolutional neural networks (CNNs) 500, and visualization device 520 acquiring 2-D RGB images. The system generates anchor vector 550 in a semantic space from a two-dimensional 2D RGB anchor image provided to a first RGB CNN 519. The system generates a positive vector and negative vector 560, 570 in the semantic space from a negative and positive image provided to a second normalization CNN 530. The negative and positive images are normal map images from prestored three-dimensional 3D CAD models. The system applies a cross-domain deep metric learning algorithm to extract image features in the semantic space using the anchor, positive, and negative vector, e.g. by selecting smallest distance vectors. The cross‑domain algorithm is a triplet loss algorithm. The second CNN is a Siamese network. CNNs 500 employ a skip‑connection architecture. Recognition by analysing the extracted features in the semantic space allows determining whether an invalid repair sequence occurred. For example, a repair step requires a part to be detected and the two-branch CNNs 500 are trained to detect whether the part is present or absent by comparing with normal map images including the part and not including the part.

Title: Flexible delivery system and implantable stent for surgical use
Inventor: ARDLE TOMAS MCDONOUGH
IPC: A61M25/00
Filed: 2019-02-12
Abstract: The invention is a tube, which would be used to facilitate the movement of an object through the lumen of the tube or over the outside of the tube. The invention could also be used as a stent designed for indwelling in a body, where its purpose would be to assist in the drainage of liquid from one part of the body to another. The expected use of the tube would be in minimally invasive surgical procedures where greater flexibility, radial strength and pushability than that provided by prior art are desirable to improve the speed of operations and the success rate of operations; to reduce the level of trauma caused to patients and to improve patient recovery rate. It could have use in applications requiring an exceptionally flexible and highly pushable tubing such as invasive surgery in vessels that are or have become tortuous and narrow, such as veterinary procedures for small animals, paediatric ureteral conditions, angioplasty for certain conditions and certain neurovascular work.
