Abstract:
An intelligent subsystem separately supports inking functions in order to allow stroke-ignorant software to be supported in a stylus driven environment. This subsystem thus provides the inking capability missing in existing flat-panel display controllers. Separate inking functions are incorporated into the subsystem in order to support inking management functions which do not corrupt the display refresh buffer as it is understood by existing application software. The subsystem makes no assumptions about the application's awareness of stroke data as an input modality. Instead, the subsystem assumes that a conventional display subsystem also exists in the system. The subsystem utilizes the strobes and clocks generated by the conventional display controller to generate addresses in a memory which has physically separate address and strobe lines from the display refresh buffer. The content of this added memory is used to control the source of input to the data lines of the display. The invention can be generalized to allow any number of planes to be added to a display system providing access to that display system by any number of asynchronous processes such as inking.

Abstract:
A tamper-resistant package for protecting information stored in electronic circuitry is described. An energy source provides energy (electrical current, optical energy, microwave energy or RF energy, for example) within a region occupied by the circuitry to be protected. The energy is applied to an energy distribution system comprising a path or paths for energy distribution. Sensing means are provided which respond to the distribution system for sensing an intrusion. The distribution system includes an arrangement for changing or altering the path or paths over which the energy travels or altering the topology of the path or paths. The sensing means is informed of the appearance of the distribution system and senses an intrusion by comparing the appearance of the path(s) with the predicted appearance. In one embodiment, electrical current is selectively applied to a subset of electrical conductors. The pattern of current flowing in the conductors is sensed and compared to an expected pattern which is determined by the subset of energized conductors.
