A remote maintenance system includes: a medical device which includes: a first power source; a first power source controller which controls an ON/OFF operation of the first power source; a checker which checks a check item; and a first communicator which transmits first information including a result of a check by the checker; and a relay unit which includes: a second power source; a second power source controller which automatically controls an ON/OFF operation of the second power source; and a second communicator which communicates with the first communicator and which receives the first information from the first communicator.

Remote maintenance system and relay unit

A personal computer to which electronic equipment, such as, an electronic camera is connected reads recording units that are recorded in the electronic camera and displays a table consisting of recording information. In recording information such as a main image, a sub image and sound in the electronic camera, data within the electronic camera are inter-related by an index which indicates that the information is part of a common recording unit. The date having the same index are output and displayed in a same thumbnail area. When a recording unit for deletion is designated from the table; check boxes are displayed according to information contained in the recording unit. For example, an 'x' is displayed in the check box of the information to be deleted, indicating that the information is a target of deletion. After the selection of information is completed and an 'OK' button is pressed, the personal computer sends a control command to the electronic camera and deletes the designated information. Rather than deletion, the designated information can be read from the electronic camera into the personal computer.

In order to enable a user to obtain information about a large number of recorded images, a display apparatus includes a browser window that can be switched between two modes. In the first mode, a first screen, referred to as an Icon Browser Screen, displays a list of files (that contain image data and/or additional data such as sound data and overlay image data) that are recorded in a recording apparatus such as, e.g., an electronic camera. In the second mode, a second screen, referred to as a Thumbnail Image Browser Screen, displays a series of thumbnail images of the images recorded in the recording apparatus. A thumbnail check box can be selected to switch between the two screens.

A plurality of electrodes for measuring electrocardiogarphic waveforms are attached on body surface positions that constitute a subset of the standard 12-lead system. The measured electrocardiogarphic waveforms of said subset of said standard 12-lead system are used to calculate the electrocardiogarphic waveforms of remaining leads in the said standard 12-lead system. The measured and calculated electrocardiographic waveforms are synthesized to form a standard 12-lead electrocardiogram. The invention is capable of monitoring the 12-lead electrocardiogram with a reduced number of electrodes, wherein a portion of waveforms are directly measured and used as primary information for diagnosing heart disease, and the other portion of waveforms are derived from the measured leads and are used as a secondary information for improving the accuracy of diagnosis. The invention is especially useful in monitoring ischemic heart disease and acute myocardial infarction in cases where mounting and maintaining ten electrodes to obtain 12-lead electrocardiogram is difficult, such as in ambulatory monitoring, long-term monitoring and home monitoring.

Method of deriving standard 12-lead electrocardiogram and electrocardiogram monitoring apparatus

To shorten the time required to transfer image data from a first information processing apparatus (e.g., an electronic camera) to a second information processing apparatus (e.g., a personal computer) the first information processing apparatus reduces the image data when it is determined that a slow interface is being used. Additionally, the reduced image data being transferred can be altered in size (enlarged or further reduced) prior to compression so that its size is best suited for the particular compression process.

A improved pulse oximeter comprises first and second light-emitting diodes that apply red light and infrared light, respectively, to a living tissue including the arterial blood, a photodiode for detecting optical outputs as produced after the red and infrared light of two wavelengths issuing from light-emitting diodes have been absorbed by the living tissue, a first computing unit that computes the ratio between the pulsating components of light absorbance .PHI. for the two wavelengths due to the arterial blood on the basis of the dc components and pulsating components of the respective wavelengths that are obtained from the reception outputs of the photodiode, a correction circuit that not only detects the degree of fluctuation in the absorbance ratio .PHI. as produced from the first computing unit but which also holds the pulsating components of the respective wavelengths when they are stable and which, if there is a fluctuation in the absorbance ratio .PHI., computes a corrected absorbance ratio .PHI.' using the pulsating components of the respective wavelengths that were held at the stable time and the dc components of the respective wavelengths at the present time, and a second computing unit 16 for computing the oxygen saturation of arterial blood on the basis of the absorbance ratio .PHI.' as produced from the correction circuit. This pulse oximeter permits the intended measurement to be continued consistently even if there occurs noise due to body movements and yet it is capable of measurements with good response.
