  • Publication number: 20030157920
    Abstract: The invention is a radio inside a vehicle providing each of the multiple drivers to automatically pre-set her radio adjustment settings for subsequent use. In the case of a “family car” where parents and young adults in the family share a car, the radio adjustment preferences (e.g., volume, bass, treble, etc.) for each driver are likely to be different. The more drivers there are to this “family car”, the more difficult it becomes for each driver to enjoy the comfort this radio affords because of the speaker adjustments required every time one turns on the radio.

  • Publication number: 20020197976
    Abstract: Briefly, this invention allows multiple users to activate their preferred settings for the various customizable features in a vehicle. These preferred settings are stored in memory for subsequent use. One of a multiple drivers to a vehicle, after being identified, will cause his previously stored preferred settings in the memory to be applied to the appropriate subsystems in the vehicle. The preferred settings include driver and companion seat positioning, front and rear temperature control, radio station and speaker adjustment selections, steering wheel positioning and door lock and unlock specification.

  • Publication number: 20020081984
    Abstract: A typical car radio has favorite-station buttons for storing and selecting a driver's favorite radio stations. If a car has more than one driver, then it becomes difficult for each driver to fully enjoy the comfort these favorite-station buttons offer. For example, a father's favorite radio stations may not be his daughter's. Any sharing of the favorite-station buttons is likely to be confusing when more than one driver shares the use of the same car. The confusion is especially made worse when at least one of the drivers is handicapped by either a physical disability or by senility.

  • Publication number: 20020081985
    Abstract: It is typical for a car radio to have the last-played radio station be played when the radio is turned ON. For this invention, the frequency of the last-played radio station for each driver of a multi-driver car is stored into a radio memory. And the appropriate driver identity is then linked to that last-played radio station frequency. So that under retrieval when the radio is turned ON again, only the last-played radio station frequency that is linked to the matching driver identity will be tuned to and played.

  • Patent number: 6353893
    Abstract: A new and useful sleep mode indicator system for laptop computers provides efficient use of battery power. In sleep mode, this indicator system turns OFF the typical blinking LED during the user-specified periods of unavailability. For example, a computer in sleep does not need to use electricity to identify its sleep mode status while its user is also asleep or is otherwise unavailable. This indicator system collects periods of unavailability and turns OFF the blinking LED during those periods. Also, sometimes the user may intend to operate the computer during a previously specified period of unavailability. This is reflected by the computer not in sleep mode at the start of the period and later enters temporarily into the sleep mode inside that specified period. Assuming that being the case, the present invention skips the period of unavailability just for that day. Further, the indicator system is not turned OFF any more for the rest of the specified period for that particular day.

  • Patent number: 6203167
    Abstract: Our invention has to do with an electrical light fixture for brightening the usually dimmer portion of a drawer storage area. Also, this electrical light fixture is small enough to be attached to an inside surface of a desk. When attached, it is preferably located immediately above the storage area of a desk drawer. This invention does not take away the drawer space available for storage. Also, this electrical light fixture uses battery power for providing automatic lighting turn-on when the drawer is opened and for providing automatic turn-off when the drawer is closed. Alternatively, the automatic turn-off occurs after a pre-determined amount of time. This light fixture is especially convenient for those people who have vision difficulties either because of an illness, a surgical operation or just because of age such as being young children or elderly people.
