Abstract: Apparatuses and methods for generating therapeutic compressed acoustic waves (e.g., shock waves) with an improved acoustic wavefront. In the apparatuses, a housing is defined by a chamber and a shockwave outlet, the chamber is configured to be filed with liquid, a plurality of electrodes defining one or more spark gaps and an acoustic reflector can disposed in the chamber, and a pulse generation system configured to apply voltage pulses to the electrodes at a rate of between 10 Hz and 5 MHz. The improved acoustic wavefront is achieved via a free-form acoustic reflector and/or a stable spark gap location. The free-form acoustic reflector is designed according to a disclosed method including iterating reflector shape using spline interpolation based on defined variables. Additionally, a stable spark gap location is achieved via a single servomotor that adjusts both electrodes simultaneously.

Abstract: Storage circuits (180-183 and 280-281) may be used for low power operation while allowing fast read access. In one embodiment (e.g. circuit 100), shared complementary write bit lines (101, 102), separate read bit lines (103-106), a shared read word line (107), and separate write word lines (108-111) are used. In an alternate embodiment (e.g. circuit 200), shared complementary write bit lines (201, 202), a shared read bit line (203), separate read word lines (206-207), and separate write word lines (208-209) are used. The storage circuit may be used in a variety of contexts, such as, for example, a register file (17), a branch unit (15), an SRAM (19), other modules (20), a cache (18), a buffer (21), and/or a memory (14).

Abstract: A circuit (50) that receives dynamic signals performs both logic and latching to achieve high speed operation. The circuit has a clock that defines both an evaluation phase and a precharge phase in which the dynamic signals are evaluated during the evaluation phase. The circuit (50) functions by precharging a latch node (INT) during the evaluation phase then performing evaluation as well during the evaluation phase. The evaluation results in providing a valid logic state to the latch node. A latch circuit (54) latches this valid state during the precharge phase and holds it in this valid state during the precharge phase. This can be adapted to select which one of the dynamic signals is to be coupled and latched on the latch node (INT).

Abstract: A circuit provides latched data in a domino circuit environment. The circuit receives a pair of input signals that are either in complementary logic states, which is data, or in the same logic state, which is the reset condition. The circuit responds to the complementary logic states by providing intermediate signals and output signals in corresponding complementary logic states. The intermediate logic states are latched by cross-coupled clocked inverters prior to the pair of signals switching from data to reset. The intermediate signals are thus latched in the complementary logic states that correspond to data even after the pair of input signals have returned to reset. The output signals are also thus provided in complementary logic states that correspond to data prior to the input signals being reset.
