摘要:
A storage device allows the state of charge of a main battery to be determined by measuring the state of charge of a dummy battery. The storage device may provide power to an electronic appliance such as a portable computer. The main and dummy batteries each have a storage capacity and a self-discharge rate. The storage capacity of the dummy battery is less than the storage capacity of the main battery; for example, the storage capacity of the dummy battery may be only about 1% of that of the main battery. The main and dummy batteries are configured so that the self-discharge rates thereof are substantially equal. The storage device also includes discharge circuitry which is configured so that the dummy battery discharges at a rate faster than the main battery when a load is connected to and drawing current from the main battery.

A medium includes a plurality of Fabry-Perot cavities of varying depths. The cavities correspond to different colors which are produced by the respective cavities under incident light. A thermo-sensitive material covers the plurality of cavities. The cavities are selectively exposed by heating portions of said thermo-sensitive material to alter the thermo-sensitive material where heated thereby forming an image.

A battery pack includes battery storage. The battery storage has a positive terminal and a negative terminal. A power connector is connected to the positive terminal of the battery storage. A ground connector is to the negative terminal of the battery storage. The battery pack also includes an additional connector. Battery monitoring circuitry is used to monitor the battery storage. The battery monitoring circuitry has a power input. Disconnect circuitry is connected to the positive terminal of the battery storage, to the ground connector, to the additional connector and to the power input of the battery monitoring circuit. The disconnect circuitry, in response to a first voltage pattern on the additional connector, electrically connects the power input of the battery monitoring circuitry to the positive terminal of the battery storage. In response to a second voltage pattern on the additional connector, the disconnect circuitry electrically disconnects the power input of the battery monitoring circuitry from the positive terminal of the battery storage.
摘要:
A method and system for displaying an image in three dimensions during a frame period. The method includes generating a left image sub-frame and a right image sub-frame. The left image sub-frame defines a visual perspective of a left eye and the right image sub-frame defines a visual perspective of a right eye for the image. The method further includes displaying the left image sub-frame utilizing a first plurality of colors and displaying the right image sub-frame utilizing a second plurality of colors. The first plurality of colors is distinct from the second plurality of colors.
