Abstract: An apparatus which can objectively assess and display to what extent and to which disease the subject belongs based on the signals of changes in hemoglobin amount measured by the optical measurement apparatus is provided. The disease assessment apparatus comprises the feature extraction unit 15 for extracting features of the hemoglobin waveform, the feature analysis unit 16 and the storage unit 12 for storing features by each disease as database. The disease is assessed by extracting various kinds of feature amounts from the hemoglobin signals of the subject measured by the optical measurement apparatus in the feature extraction unit 15 and by applying multivariate analysis of similarities between feature amounts extracted and feature amounts stored by disease in the storage unit 12. Results of assessment are shown as scores expressing similarity with each disease group in a bar graph.

Abstract: A remote control apparatus for controlling multiple propulsion units of a boat is provided. The remote control apparatus, in one embodiment, comprises a body having a first control lever and a second control lever. An electronic control unit is disposed within the body of the remote control apparatus and comprises a storage device and a contact member. The storage device can store a correction value for claibrating the control levers, while the contact member determines when correction values can be entered into the storage device when the contact member is in an enabled state. The remote control apparatus can be calibrated before the apparatus is installed on the boat, thereby eliminating the need for an operator to calibrate the remote control apparatus. A boat having the remote control apparatus described herein and a method for storing a calibration value for the control lever are also provided.

Abstract: A principal component analysis or an independent component analysis is conducted on the living body signals, e.g., local cerebral blood amount change signals obtained by the living body optical measurement to extract and display multiple component signals thereof. Signals other than the component signals containing noise are selected from these component signals automatically or manually, and the local cerebral blood amount change signals are reconstructed by using selected signals. The reconstructed signals is displayed and further subjected to the component analysis or the reconstruction as appropriate, and used for the profiling of information necessary for the diagnosis. Consequently, high-precision target signals can be obtained by completely removing external noise included in the living body signals, particularly the noise which cannot be adequately removed by the moving average and the filtering processings.
