Abstract:
The present invention teaches a variety of methods and systems for providing computer/human interfaces. According to one method, the user interfaces with an electronic device such as a computer system by engaging a sensor with desired regions of an encoded physical medium. The encoded physical medium is preferably chosen to provide intuitive meaning to the user, and is thus an improved metaphor for interfacing with the computer system. Suitable examples of the encoded physical medium include a data-linked book, magazine, globe, or article of clothing. Some or all of the selected regions have had certain information encoded therein, information suitable for interfacing and controlling the computer system. When the user engages the sensor with a region having certain encoded information, the certain encoded information is interpreted and an appropriate action taken. For example, the sensor or the computer system may provide suitable feedback to the user. The encoded physical medium may have text and/or graphic illustrations that draw the user in or provide meaningful clues or instructions perhaps related to the encoded information. The sensor may have at least one identification number (ID) providing information such as user identity, sensor type, access type, or language type. The sensor can transmit the certain decoded information together with the at least one ID to the computer system.
Abstract:
An electrical system of a vehicle has a starting battery and a reserve battery. The charge of the starting battery is maintained by a charge maintenance device under control of a controller which couples energy from the reserve battery to the starting battery during periods when the vehicle is not being used or during periods of operation where the starting battery voltage requires additional charge.
Abstract:
A method and apparatus for determining the state of charge of a battery include use of multiple battery tests to provide complementary insight into battery condition before, during, and after battery charging. Battery testing is performed using a light resistive load, a heavy resistive load, a conductance tester, and a battery charger. During a preliminary charging stage, average battery current and a predicted battery temperature are used to determine whether or not the battery is capable of being substantially fully charged, thereby permitting avoidance of unneeded charging. In the later charging stage, the rate of change of battery cold cranking amps is monitored to detect an end of charge condition.

Abstract:
A dual battery or back-up battery system includes a control and indicator circuit for driving the battery switch. The battery switch is coupled between the positive terminals of the primary battery and auxiliary battery. The control and indicator circuit includes an indicator such as an LED, an indicator switch such as a single pole, single throw switch, and a driver circuit. The driver circuit includes a voltage tripler for appropriately driving a MOSFET battery switch. The indicator requires only a single signal conductor between the driver circuit and the indicator switch or indicator light. The indicator switch may also be utilized to provide a signal to a computer or other control circuit. The indicator switch and indicator are advantageously located within the interior of an automobile so that the operator may easily monitor and control the battery switch.
