Abstract: A monitoring system can protect the privacy of a treatment recipient while monitoring the treatment recipient being treated. A transmitter transmits a beacon signal. A beacon detector detects an RSSI(2) of the beacon signal. A monitoring device includes an imaging element, an open-close body, a beacon detector, an obtainer, and an open-close body controller. The imaging element captures an image of a treatment recipient being treated by a treatment provider through an opening. The open-close body opens and closes the opening. The beacon detector detects an RSSI(1) of the beacon signal. The obtainer obtains the RSSI(2) detected by the beacon detector. The open-close body controller controls opening and closing of the open-close body based on the RSSI(1) detected by the beacon detector and the RSSI(2) obtained by the obtainer.

Abstract: In an optical disk recording and reproducing device which uses an optical disk having at least a first recording layer and a second recording layer, a thickness of a spacer section between the first recording layer and the second recording layer is measured, an amount of defocus with respect to the second recording layer is set based on the measured spacer thickness, and a focus servo operation is performed for focusing the laser light irradiated from an optical pickup device on the second recording layer.

Abstract: A DC voltage value is obtained at least at an inside position, an intermediate position, and an outside position on a disc (1) from a drive signal that is supplied to a focusing coil (4) built into an optical pickup (2). From the DC voltage values is obtained a relationship of a position between the respective positions and the DC voltage value, and this relationship is stored into a memory circuit (12). Then, during recording or playback, the DC voltage value that is calculated on the basis of the recording or playback position of the signal at that time and the AC signal included in the drive signal that is supplied to the focusing coil (4) are added to create a signal to be supplied to a tilt adjustment coil (6).

Abstract: An optical disk unit is incidence a light spot upon an optical disk. The light spot is radially moved to cross tracks formed on the optical disk. The tracks are provided with specific access marks. The number of access marks passed by the light spot as well as the number of tracks crossed by the light spot until a change is found in a detected access mark are counted. The latter number is divided by the former number and multiplied by a coefficient to provide a speed signal indicative of a speed of the light spot relative to the optical disk.

Abstract: A signal recording apparatus comprising the operation portion to be manipulated when it is found necessary to record a signal on a recording medium while the signal is being produced, a signal conversion circuit for converting the signal to a digital signal, a memory circuit of specified capacity for temporarily storing the digital signal from the conversion circuit and thereafter feeding the signal to a signal recording head, and a main control circuit for controlling the memory circuit for storing the signal therein and reading out the signal therefrom. In response to a recording start instruction given by the operation portion, a system for driving the recording medium is initiated into operation, and at the same time, the signal is read out from the memory circuit retroactively since a predetermined time interval prior to the manipulation of the operation portion and is recorded on the medium.
