Abstract: Apparatus, systems and methods are provided that include a repository for receipt of an object and a mechanism for shielding from view the object. The repository may take the form of a mailbox and the object may be a letter, e.g., a letter addressed to Santa. The shielding mechanism is actuated by a trigger that is associated with the repository and, in exemplary embodiments, is triggered by an activity normally associated with the repository, e.g., raising a flag on a mailbox. The trigger actuation may interact with an electronic control system, a mechanical control system, or a combination thereof.

Abstract: An electronics device is configured for installation in the brake light circuitry of a vehicle braking system. The electronics device is particularly configured to provide a flashing or pulsing appearance for a brake light, such as an automobile CHMSL. The pulsing is accomplished in a precise manner and that provides additional operational safety features than standard automotive brake lights. The electronics device is configured to avoid over-triggering of the pulsating lights due to multiple application of the automobile's brakes in a short time frame. The electronics device is further configured to function correctly even if the automobile is equipped with sophisticated computer systems that analyze the brake light circuitry, and is configured to avoid detection as a problem by the vehicle's diagnostic systems. At the same time, the electronics device will still allow the vehicle's diagnostic scans to detect any actual problems with the brake light system without hindrance.

Abstract: A data processor 2 has privilege levels associated with it including a user level and a privileged level. The processor 2 also has multiple stack memories which can be used including one or more process stacks, a main stack and a deep stack. The stack memory to be used is de-coupled from the privilege level. An activation level state variable tracking the number of pending exceptions is held by the processor and used to modify which stack memory stores pending state values when an exception occurs. If the system is at a base level of activation, corresponding to currently no pending exceptions, then when an exception occurs the current state data is saved on the process stack with the main stack being available for the exception handling code. Particular exceptions can be flagged as requiring use of a deep stack rather than either the process stack or the main stack.
