Embodiments of the present invention provide a system, method, and computer program product for updating software on an embedded computer device. According to one aspect of the present invention, a concurrent embedded application update is performed in which selected state information for one or both of an embedded virtual machine and a plurality of applets on an embedded computer device is securely exported to a host computer device. After software updates have been installed, the selected state information can be restored on the embedded computer device from which it was exported and/or it can be migrated to a second embedded computer device.

According to exemplary embodiments, a computer program product for providing voltage to a memory device includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method performed includes storing data on the memory device, providing a voltage from a finite energy storage medium to the memory device when power is not provided by an associated computing system and measuring the voltage provided. The method also includes boosting the voltage provided by the finite energy storage medium via a switching voltage regulator responsive to the voltage being below a threshold, wherein the switching voltage regulator is coupled to the finite energy storage medium.

According to the present invention, there is provided a method, system and program storage device for displaying textual information associated with a defined video object in video data on a video display device, comprising: sampling a video object plane to determine whether the video object is in the video object plane for displaying the video object on the video display device; updating a location of the video object in the video object plane as the video object moves during display of the video data on the video display device; determining whether a pointing device is over the updated location of the video object; and displaying the textual information associated with the video object on the video display device for a predetermined period of time.
摘要:
A light source, which has a time varying chromatic output, back lights or front lights a plurality of liquid crystal displays disposed in a desired arrangement. Two different colors can be produced at two different times by using a fluorescent light as the light source. The fluorescent light is a sealed tube having a high vacuum with an insert gas therein for energization of the gas and a low pressure mercury vapor. The tube has a coating on the inner surface of the tube of at least one phosphor. Energization of the inert gas causes the low pressure mercury vapor to arc to produce light of a first color during a first time period with the light of the second color being produced solely from the phosphor coating upon the gas being deenergized during the second time period. Each of the liquid crystal displays can be activated during the first time period, the second time period, both time periods, or remain inactivated during both time periods. This selective activation or inactivation of each liquid crystal display produces displayed information in the first color, the second color, or both colors. By forming the coating of a mixture of two phosphors with substantially different persistence times, a second color is produced during the second time period from the phosphor mixture, and a third color is produced during a third time period after the second time period solely from the phosphor having the longer persistence time.
