International Classification:

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.

Abstract:

Intelligence is added to a computer sleep mode indicator system. A method for an intelligent indicator system is provided to turn off the sleep mode status indicator of a computer during sleep mode when a user is known to be unavailable to monitor the indicator, for example, when the user is sleeping or having lunch. This embodiment also handles reasonable variations of user habits. Further, to account for a gradual change of user unavailability habits over time, this invention obtains and applies a user unavailability intelligence by dynamically modifying the beginning and the ending times of a specified user unavailability period based on user experience. One preferred method for dynamically modifying the beginning and ending times is by calculating the moving averages of the actual sleep mode entry and exit times that occurred within a pre-determined period from the specified beginning and ending times.

US Classification:

455/186100, 455/187100

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. In this manner, as driver A turns on the radio, the last-played radio station when driver A was last listening to in the car will be played, and the same for each of the other drivers to the same car. Each driver will operate the radio as if he is the only driver that uses the car.

International Classification:

F21V 3300

US Classification:

362133

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.

International Classification:

G05D 2300

US Classification:

701 49

Abstract:

The present invention includes a temperature-dependent power window and sunroof system for an automotive vehicle. This system according to the present invention is activated when the vehicle is presumably parked and left unattended by a vehicle operator. One aspect of the invention is directed to the detection of actions by the vehicle operator as input for system activation and deactivation, for example, the operator removes the ignition key, opens the driver door, closes the driver door and locks the door. Advantageously, if the vehicle operator stays in the vehicle after the key is removed from the ignition cylinder, the present invention remains inactivated whereby affording the maximum flexibility to the car driver. One preferred embodiment maintains a "comfortable" temperature range for the interior of the vehicle over the time period the vehicle is parked and left unattended. Moreover, to actively maintain the "comfortable" temperature range for the vehicle interior, a separate algorithm may be used.

Abstract:

An output device for providing output service to a mobile information apparatus without requiring a device specific output driver installed at the mobile information apparatus. The wireless output device may include an operating system, a wireless communication unit for radio frequency communication, a display screen, and a user interface over the display screen, the output device may include features for installing one or more application software at the output device for expanding the capabilities of the output device, registering the output device with a control point over a network and providing an identification of the output device for enabling one or more mobile information apparatuses to transmit output data to the output device. Subsequent to registering the output device and providing the identification information of the output device, the output device receives output data associated with the identification information from the mobile information apparatus for rendering.
