摘要:
The present invention produces at least two sound signals such as warning signals or actuating signals by one sounder having a resonant frequency, wherein one of the sound signals is indicated by the resonant frequency of the sounder to enable a higher intensity sound to be produced.
摘要:
An indication system of a camera for audibly and distinguishably indicating at least two different kinds of information of the operating state of a self-timer, a warning against the photographing operation for insufficient brightness of the object or low range of a shutter speed, the voltage checking of a battery and the other necessary information for photographing operation. The indication system comprises an acoustic device having a sound which varies in volume, tone or time interval thereof in accordance with various kinds of output signals of a controlling circuit for digitally controlling the acoustic device by means of counting signals of a binary counter.
摘要:
A camera includes an abnormal state detecting circuit for detecting an abnormal state of the camera, a counter for counting the number of times for which the abnormal state of the camera is detected by the abnormal state detecting circuit, and a setting instruction circuit for setting the camera into an operation inhibiting mode in response to a counted value of the counter when the abnormal state of the camera has been detected by the abnormal state detecting circuit a predetermined plural number of times.
摘要:
A camera which has an objective lens for forming an object image on a film, and a pseudo telescopic information input device for recording on the film pseudo telescopic information for selecting a field smaller than an actual field of the objective lens, and also has a device for inhibiting switching of information input by the pseudo telescopic information input device during a multiple exposure photographing operation.
摘要:
A battery checking circuit constructed with a pulse generating circuit for producing a pulse in response to operation of a camera, a counter for counting the pulses produced from the pulse generating circuit, a display divided into a plurality of parts for displaying the remaining amount of electric energy of a battery according to the number of energized display parts, and a display control circuit for controlling the display in accordance with the output of the counter.
摘要:
The present patent application discloses a reactuating device for a strobe having brightness level detecting apparatus for detecting the brightness level of an object to be photographed to determine whether or not flash illumination is necessary, and (or) charging-incompletion detecting apparatus for detecting that the storage capacitor in the strobe is not fully charged, whereby when the brightness level of the object becomes so low that strobe photography is necessary, and (or) when the strobe is not fully charged, as soon as this is detected, a charging of the strobe begins.
摘要:
In the disclosed camera, the display indicating the camera's operating condition is visible from outside of the camera housing. When a lens cap, barrier, or other operating member makes it substantially impossible to expose the film in the camera, the information on the display is erased to warn the user that the camera is not ready for shooting film.
摘要:
A networked health care and monitoring system (10) capable of providing an updated reliable vital information on the health condition of individuals and adapted to support home health care and maintenance. The system includes testing and measuring instruments (39; 43; 46; 49; 56) associated with certain household appliances such as a toilet system (12) and adapted to monitor the vital information passively in response to the use thereof in connection with routine living activities of the individuals. The system may further include control devices (39; 46; 49; 56) associated with certain household appliances, such as an ergometer (15), having health care and maintenance functions and adapted to control the appliances based on the vital information monitored by the testing and measuring instruments in the system. In one embodiment wherein the system is arranged in the centralized network configuration, the testing and measuring instruments and the control devices are connected via a local area network with a data controller (20) wherein all the vital information obtained in the system is stored. Instruments and devices (39; 43; 46; 49; 56) are permitted to access the controller through the network to retrieve necessary vital information therefrom. In another embodiment arranged in the distributed network configuration, the vital information obtained by respective measuring instruments is stored therein and is furnished upon request to the other appliances.
摘要:
The disclosed light measuring arrangement is positioned to receive and measure light from a focusing screen on which a display of focusing conditions is superimposed. A correcting circuit corrects the object brightness sensed by the light measuring arrangement. When display segments of the display are selectively switched on and off, the correcting circuit produces an output signal representing a corresponding brightness correction factor which is applied to the light measuring arrangement.
摘要:
A rear light condition detecting device for a camera is arranged to measure distances to a plurality of parts appearing within a taking picture plane on the assumption that an object located nearby is the main object to be photographed or that a light source such as the sun is among faraway objects. The device determines the object to be in a rear-light or counter-light condition in cases where the luminance of the nearby object is extremely lower than other objects or that of a faraway object is extremely higher than other objects.
