A pump connector adapter (110) for an electrosurgical device is provided. The adapter (110) has a body (112) having a flow passage therethrough. An absorption member (130) can then be provided to collect fluid within the body (112).

A dental scan aid 12 is provided comprising a scan substrate 14 having a randomised irregular surface 16 unique to the dental scan aid 12. There is a connection means to allow the scan substrate 14 to be fixed relative to a patient's maxillary or mandibular arch 10a, 10b. There is also a regular structure 24 extending from the randomised irregular surface 16 to thereby provide fixed positional information relative to the maxillary or mandibular arch 10a, 10b to improve dental scan accuracy when the dental scan aid 12 is in position.

A method for generating a principal predictor model from multi-dimensional time series data, comprises: receiving, from a plurality of sensors, multi-dimensional time series data corresponding to a plurality of original variables; transforming the multi-dimensional time series data to a lower dimension to define reduced-dimensional time series data; extracting, by a controller, a plurality of latent variables from the reduced-dimensional time series data and determining values of the plurality of latent variables in a first time period; initializing, by the controller, a loadings matrix corresponding to a set of latent variables of the plurality of latent variables; and determining, by the controller, one or more principal predictor model parameters, by performing an iterative process. The iterative process comprises (a) predicting values of the plurality of latent variables based on the reduced-dimensional time series data and the loadings matrix, by using an estimation process which maximizes a covariance between the values of the plurality of latent variables and the predicted values of the plurality of latent variables; (b) calculating a new loadings matrix from the loadings matrix and the predicted values of the latent variables; (c) updating the loadings matrix based on the calculated new loadings matrix; and (d) iteratively repeating (a) to (c) until the one or more principal predictor model parameters reach convergence.

A multi-port valve includes a valve housing (20), a valve core rotatably mounted to the valve housing (20) and a sealing gasket (40/40a/40b/40c) disposed between the valve housing (20) and the valve core. The valve housing (20) defines a plurality of valve ports (22). The valve core defines a plurality of flow channels (32). The sealing gasket (40/40a/40b/40c) is provided with a plurality of openings (42/42a/42b/42c) arranged at intervals in a circumferential direction and a plurality of first ribs (44/44a/44b/44c) respectively arranged between adjacent two of the openings (42/42a/42b/42c). The flow channels (32) extend through an end of the valve core facing the sealing gasket to define a plurality of channel ports (34/34a/34b/34c); the channel ports (34/34a/34b/34c) are arranged at intervals in a circumferential direction with a plurality of second ribs (35/35a/35b/35c) respectively arranged between adjacent two of the channel ports (34/34a/34b/34c). each of the first ribs (44/44a/44b/44c) or second ribs (35/35a/35b/35c) forms two wing portions (36/36c/46a/46b) at circumferential sides thereof to make a portion of the first or second rib has a larger circumferential width than other portion thereof.
