Abstract: Embodiments of the invention are directed to an apparatus and method for creating folded multi-dimensional shapes from pliable substrates. An apparatus having a handle connected to one or more plungers that are configured to move along a longitudinal axis is used to form folds in a flat substrate by pressing dies attached to the plungers into a die area to shape the flat substrate. The handle is depressed multiple times to achieve the desired number of folds in the substrate. The apparatus may include one or more plunger adjustment mechanisms to switch use of the one or more plungers to create different sets of folds in the substrate with each depression.

Abstract: A closed loop handlebar locking device is securely coupled to a bike allowing safe and accurate steering of the bike. Device is further suitable for locking the bike when not in use. Device is configurable to lock a bike to a fixed object, such as a signpost while still attached to the stem of the bike. The device is also configurable to lock the bike when a suitable object is not available. In such a situation the device may be removed from the stem, passed around the frame and through one or both wheels. The device is attached to the stem via a stem piece that remains attached to the stem when the device is detached. Brakes, lights, computer and other accessories and components are attached to the stem piece. The bike is unsuitable for operation if the handlebar locking device is defeated by a would-be thief.

Abstract: An integrated circuit device provides a choice of external pins (connections) that may be user selectable for coupling an external filter/stabilization capacitor to an internal voltage regulator. However, connecting the output of a internal voltage regulator to an uncharged external filter/stabilization capacitor (or to a capacitor charged to a different voltage level than the internal regulation voltage) through a low impedance path can cause the regulator output voltage to sag/spike if the internal voltage regulator tries to charge/discharge the capacitor up/down to equilibrium with the regulator output voltage. To minimize this potential sag/spike, the voltage on the external filter/stabilization capacitor may be adjusted in a controlled manner to substantially the same voltage as the voltage on the output of the internal voltage regulator, and then the internal voltage regulator is operationally coupled through a low impedance to the external regulator filter/stabilization capacitor.

Abstract: An internal voltage regulator in an integrated circuit device is always active upon initial start-up and/or power-on-reset operations. The internal voltage regulator protects the low voltage core logic circuits of the integrated circuit device from excessively high voltages that may be present in a particular application. In addition, nonvolatile memory may be part of and operational with the low voltage core logic circuits for storing device operating parameters. Therefore, the internal voltage regulator also protects the low voltage nonvolatile memory from excessive high voltages. Once the integrated circuit device has stabilized and all logic circuits therein are fully function, a bit(s) in the nonvolatile memory may be read to determine if the internal voltage regulator should remain active, e.g., how power operation with a high voltage source, or be placed into a bypass mode for low power operation when the integrated circuit device is powered by a low voltage.

Abstract: An amplifier may be configured as a general purpose operational amplifier having external gain determining components or as a programmable gain amplifier having self-contained gain determining components and fixed step amplification selection. Configuration and control of the operational amplifier may be performed with a digital processor such as a microcontroller. The configurable amplifier may be packaged in an integrated circuit package. The configurable amplifier and a processor may be fabricated on a single integrated circuit or in a multi-chip integrated circuit package.
