Abstract: A method and system for an application to load one or more files from a device (e.g., local disc of the device) rather than from a location outside of the device (e.g., a server) via a service worker. The service worker can communicate with one or more main JavaScript threads (e.g., clients) via one or more corresponding service worker bridges that communicates with one or more corresponding main JavaScript thread bridges that communication with the main JavaScript threads. The main JavaScript threads can communicate with the local disc of the device (e.g., native) to retrieve the one or more files and transmit them to the service worker such that the service worker can provide the one or more files to the application. In this manner, service workers can provide service with data stored in a memory of a computer device of a computer.

Abstract: A flat panel display assembly includes an array of micromachined incandescent lamps. According to one aspect of the invention, the array of lamps is placed on a gas filled enclosure to enable the filaments to be operated at higher temperatures with extended lifetimes. According to another aspect of the invention, each lamp (or groups of lamps) may be formed in its own gas filled pocket. In some embodiments, a diode is connected in series with each lamp filament. This arrangement enables the array to be operated such that power is applied to the row (column) at a time and to selected columns. The effective brightness of each lamp may be controlled by determining the length of time each lamp is turned-on.

Abstract: An electromagnetic radiation (EMR) responsive detector includes an array of multi-layered cantilevers with each cantilever having at least a first layer for absorbing EMR signals and a second layer for reflecting light incident on the second layer. Each cantilever is formed so it can absorb EMR which gets converted into heat which then causes the cantilever to bend proportionately to the amount of EMR energy it absorbs. The amount of EMR absorbed by each cantilever of the array is optically read-out (sensed) by illuminating the cantilevers of the array and sensing the light reflected from each cantilever. Various schemes for projecting light onto the array and sensing the reflected light are disclosed. The optical read-out of the array eliminates the need for electronic read-out circuitry and accessing wires to be formed on the array.
