  • Publication number: 20030164014
    Abstract: To provide a lock-confirmation supporting device which helps a user to do the lock confirmation with the senses of a human being easily and surely at the time right after the locking operation, and to do the lock reconfirmation easily after being locked. A lock-confirmation supporting device is constituted of a key holder portion (2) in which a key is held and out of which it is taken by a user for locking and an electronic clock portion (3) comprising a clock circuit, CPU, ROM, RAM and a display unit. The lock-confirmation supporting device generates a lock-confirmed signal upon the user's key-returned action right after the locking oepration. Upon the lock-confirmed signal, the lock-confirming device stores in the RAM of the electronic clock portion (3) the real time as the lock-confirmed time and informs the user of the lock-confirmed time by displaying it on a liquid crystal display unit (18).

  • Publication number: 20020093429
    Abstract: A medication-taking confirmation support device includes a pill case having a pill housing section, an electronic clock equipped with a memory, a notification unit and a controller, a pill case open/close sensor, and a reconfirmation signal input device. The controller makes the notification unit notify a medication-taking confirmation time on the basis of a detection signal from the pill case open/close sensor and also makes the memory store the medication-taking confirmation time at the time of taking medication. The controller further makes the notification unit re-notify the medication-taking confirmation time read out from the memory on the basis of a signal from the reconfirmation signal input device after having taken medication.
