Abstract: A window breaking system has a seatbelt buckle interfaced to a vehicle through a seatbelt and a seatbelt receiver interfaced to the vehicle for removably receiving the seatbelt buckle. A window breaking mechanism is integrated to the seatbelt buckle such that, in the event escape from the vehicle is needed, the seatbelt buckle is released from the seatbelt receiver and the window breaking mechanism is used to break a window, through which the user (occupant) is now able to escape.

Abstract: A microarchitecture and instruction set that supports multiple, simultaneously executing threads. The approach is disclosed in regard to its applicability in connection with a recently developed microarchitecture called “WaveScalar.” WaveScalar is a compiler that breaks a control flow graph for a program into pieces called waves having instructions that are partially ordered (i.e., a wave contains no back-edges), and for which control enters at a single point. Certain aspects of the present approach are also generally applicable to executing multiple threads on a more conventional microarchitecture. In one aspect of this approach, instructions are provided that enable and disable wave-ordered memory. Additional memory access instructions bypass wave-ordered memory, exposing additional parallelism. Also, a lightweight, interthread synchronization is employed that models hardware queue locks. Finally, a simple fence instruction is used to allow applications to handle relaxed memory consistency.
