Disclosed is a camera device including: a camera body; a transparent lens cover configured to cover a lens portion of the camera body; and a guard member configured to protect the lens cover from external impact, in which a projecting part is formed in the guard member, and when the camera device is mounted on a target object, the camera device is in a first state in which the lens cover is disposed between the projecting part of the guard member and the target object, or is in a second state in which the projecting part of the guard member is disposed between the lens cover and the target object.

Camera device

A visual restoration aiding device for restoring vision of a patient comprises: a plurality of substrates which are placed on or under a retina of a patient's eye; a plurality of electrodes which are mounted on each substrate to apply an electrical stimulation pulse signal to cells constituting the retina; and a connecting unit which has flexibility and connects the substrates.

Visual restoration aiding device

A visual restoration aiding device for restoring vision of a patient comprises an electrode array having a plurality of electrodes placed on or under a retina of an eye of the patient for applying an electrical stimulation pulse signal to cells constituting the retina; a photographing unit which photographs an object to be recognized by the patient; a converting unit which converts photographic data transmitted from the photographing unit to data for electrical stimulation pulse signals; and a control unit which outputs an electrical stimulation pulse signal through each electrode based on the data for electrical stimulation pulse signals so that the control unit produces pulse output through one of a first electrode and a second electrode during a halt time of pulse output through the other electrode, the first and second electrodes being arranged within a distance such that electrical stimulation pulse signals outputted therethrough at substantially the same time are likely to interfere with each other.

An artificial vision system for regenerating or restoring vision of an eye of a patient includes: a power acquiring unit which is disposed inside the eye, includes a magnetic core having an opening and a coil wound around the magnetic core, and is adapted to acquire power from outside a body using electromagnetic induction; and a plurality of electrodes which is provided at a retina and is adapted to electrically stimulate cells constituting the retina.

Artificial vision system

A visual restoration aiding device including an electrode array having a plurality of electrodes placed on or under a retina of an eye of the patient for applying an electrical stimulation pulse signal to cells constituting the retina; a photographing unit which photographs an object to be recognized by the patient; a converting unit which converts photographic data transmitted from the photographing unit to data for electrical stimulation pulse signals; and a control unit which outputs an electrical stimulation pulse signal through each electrode based on the data for electrical stimulation pulse signals so as not to simultaneously output the electrical stimulation pulse signals through electrodes arranged within a distance that electrical stimulation pulse signals outputted through the electrodes will interfere with each other and which switches between the electrodes used for outputting the electrical stimulation pulse signals and the electrodes unused for outputting the electrical stimulation pulse signals.

A non-contact type tonometer includes a fluid blowing device which blows fluid against a cornea of an eye of an examinee; an intraocular pressure measurement part which detects a deformed state of the cornea caused by the blown fluid and determines intraocular pressure of the examinee's eye based on a result of detection of the deformed state; a pulsation detection part which detects pulsation of the examinee; a measurement timing determination part which can determine a measurement timing based on the detected pulsation to obtain a predetermined number of results of measurement on the intraocular pressure in synchronization with different phase points in the pulsation; a command signal input part which inputs a command signal for execution of the measurement; and a control part which outputs a control signal for controlling driving of the fluid blowing device based on the determined measurement timing and the input command signal.

Non-contact type tonometer

A vitreous surgical apparatus in which an inner tubular blade is moved in an axis direction with respect to an outer tubular blade by supply and exhaust of compressed air to excise a part of a vitreous body in an eyeball and aspirate and discharge the excised part out of the eyeball, the apparatus including: a plurality of solenoid valves each of which is opened and closed for performing the supply and exhaust of the compressed air; and a control unit which synchronously drives the solenoid valves to open and close in order to move the inner tubular blade at a desired cutting speed.

Vitreous surgical apparatus

A camera apparatus which includes a casing; a pan unit having an external video incident section; a pan shaft; a pan shaft support; pan driving means for rotating the pan unit about the pan shaft; a tilt unit having an internal video incident section and tilt face; a tilt shaft; tilt driving means for rotating the tilt unit about the tilt shaft; and a camera disposed inside the tilt unit. This configuration allows to visibly recognize the movement of the camera, and increases the design flexibility by covering an internal mechanism. Moreover, the apparatus may be downsized by reducing the unused space inside. Furthermore, a simple mechanism increases the productivity of the camera apparatus.

Camera apparatus

In a peristaltic aspiration pump, a plurality of rollers are equally spaced apart from a rotating shaft and rotatable about the rotating shaft. The rollers sequentially compress and occlude an aspiration tube to generate a vacuum pressure within the aspiration tube. An irrigation-aspiration apparatus aspirates tissue to be removed together with an irrigation fluid supplied to an operated part via the aspiration tube, using the peristaltic aspiration pump. The peristaltic aspiration pump is driven under control to change the travelling speed of the roller in accordance with statuses of occluding the aspiration tube.

Irrigation-aspiration apparatus

A camera unit for an electronic conference is adapted to be set on a monitor, and comprises a stationary support base set on the monitor, a camera unit body provided on said stationary support base so as to be horizontally rotatable, a lens block supported to the camera unit body so as to be vertically rotatable, and a control device incorporated in the camera unit body, for controlling the rotation of the camera unit body and the lens block and the focal distance and zooming ratio of the lens block, the lens block is adapted to be turned between a horizontal position at which the lens block is stored in a recess formed in the camera unit body, and picks up a person in front thereof, and a vertical position at which the lens block is projected forward from the camera unit body so as to pick up a document set therebelow, and the control device controls the focal distance and zooming ratio of the lens block in accordance with a horizontally rotating position of the camera unit body and a vertical rotating position of the lens block.
