    • A method of detecting leaks and measuring volumes as well as a device, the Power-free Pump Module (PPM), provides a self-contained leak test and volume measurement apparatus that requires no external sources of electrical power during leak testing or volume measurement. The PPM is a portable, pneumatically-controlled instrument capable of generating a vacuum, calibrating volumes, and performing quantitative leak tests on a closed test system or device, all without the use of alternating current (AC) power. Capabilities include the ability is to provide a modest vacuum (less than 10 Torr) using a venturi pump, perform a pressure rise leak test, measure the gas's absolute pressure, and perform volume measurements. All operations are performed through a simple rotary control valve which controls pneumatically-operated manifold valves.

    • Embodiments of the invention include a multiple subscription subscriber identity module (SIM) card. The SIM card includes a plurality of sets of subscription parameters from which to select and activate a single set of parameters. The sets of subscription parameters each contain various information, e.g., information such as an Integrated Circuit Card Identifier (ICCID) and an International Mobile Subscriber Identity (IMSI), and are based on various criteria, e.g., different service regions of use for the electronic device on which the SIM card is installed. A set of subscription parameters is selected for a particular region of use either manually or automatically. The SIM card, which can include a software interface that provides a list of available sets of subscription parameters, is activated by updating the selected set of subscription parameters. Alternatively, a default set of subscription parameters is selected unless a different set of subscription parameters is selected manually from among the plurality of sets of subscription parameters. According to alternative embodiments of the invention, the selected set of subscription parameters can be deactivated and a different set of subscription parameters can be selected and updated to in the SIM card.

    • Circuits, memories, and methods for latching a write command and later provided write data including write command and write data timing circuits. One such timing circuit includes internal write command latch to latch an internal write command in response to write command latch signal. The internal write command latch releases the latched write command in response to the write command latch signal after a latency delay. The timing circuit further includes a write leveling flip-flop (FF) circuit and a write data register. The FF circuit latches the internal write command in response to an internal write command FF signal based on a write clock signal and generates an internal write enable signal in response to latching the internal write command. The write data register captures write data in response to the write clock signal and releases the captured write data in response to a delayed internal write enable signal.
