A hanger assembly includes a first decorative element and a mounting base. The decorative element has a first surface and a first elongated mounting plate joined thereto in a plane perpendicular to the first surface. The base has a rear surface fastenable to a vertical surface, a first sidewall, and a front surface within which is formed a recessed slot having a substantially T-shaped cross-section. The recessed slot extends from an open end in the first sidewall to a fixed stop formed in the mounting base and slidably receives the mounting plate. The mounting base may be used with a variety of interchangeable multi-themed decorations or plant hangers.

A card accessory device including, among other things, one or more processors and memory storing instructions that, when executed by the one or more processors, are configured to cause the card accessory device to receive, from a terminal in communication with the card, one or more messages comprising a complete message indicative of successfully reading the card and a read error message indicative that there was an error in reading the card, identify one or more predetermined sequences based on the one or more messages, and perform via a rumble pack, one or more predetermined vibration sequences comprising a first vibration sequence associated with the complete message and a second vibration sequence associated with the read error message in a predetermined pattern.

A ram air turbine (RAT) actuator can include an actuator housing, an actuator rod configured to move relative to the actuator housing through several positions, and a first biasing member, a second biasing member, and a third biasing member positioned and configured to bias the actuator rod relative to the actuator housing. The first biasing member biases the actuator rod from a first position through a second position, the second biasing member biases the actuator rod from the first position through a third position, and the third biasing member biases the actuator rod from the first position through a fourth position. The three biasing members can be configured to bias a ram air turbine against an uplock hook with sufficient force to eliminate vibrational damage to the uplock hook while in the first position.

A control circuit for a step-up converter includes a soft start module configured to control states of N transistor pairs of the step-up converter, where N is an integer greater than two. A driver module is in communication with the soft start module and configured to generate a first signal when N transistor pairs of the step-up converter are ready to switch. A first charging circuit is configured to charge (N-1) capacitors of the step-up converter to an input voltage of the step-up converter in response to the first signal and to generate a second signal when charging is complete. A second charging circuit is configured to sequentially charge the (N-1) capacitors of the step-up converter to (N-1) predetermined voltage values in response to the first signal and the second signal and before operation of the step-up converter begins.

A multi-level, step-up converter circuit includes an inductor including one terminal in communication with an input voltage supply. N transistor pairs are connected in series, where N is an integer greater than one. First and second transistors of a first pair of the N transistor pairs are connected together at a node. The node is in communication with another terminal of the inductor. Third and fourth transistors of a second pair of the N transistor pairs are connected to the first and second transistors, respectively. (N&#x2212;1) capacitors have terminals connected between the N transistor pairs, respectively. An output capacitor has a terminal in communication with at least one transistor of the N transistor pair.

A system includes a voltage regulator module, a voltage comparator module, and a current limiting module. The voltage regulator module regulates an input voltage supplied by a power supply and supplies an output current to a load. The voltage comparator module compares the input voltage to a first threshold. The current limiting module decreases the output current when the input voltage decreases to less than or equal to the first threshold, decreases the output current until the input voltage increases to greater than the first threshold, and decreases the output current by an additional predetermined amount after the input voltage increases to greater than the first threshold.

Integrated MOSFET current sensing for fuel-gauging. A 1MOSFET through which the current is to be sensed is coupled to a 2MOSFET of the same type, the 2MOSFET being biased to have the same resistance as the 1MOSFET. The 2MOSFET has a much smaller area than the 1MOSFET, and is coupled to a current source representing a maximum current through the 1MOSFET. The voltage across the 1MOSFET relative to the voltage across the 2MOSFET provides a measure of the current through the 1MOSFET. Various embodiments are disclosed, including embodiments in battery packs to eliminate the need for additional and expensive external components.

A multi-person velocipede is provided with a pair of interconnected frame members. A pair of rotatable forward wheels are rigidly coupled to the forward portion of the frames, and a pair of rotatable rearward wheels are pivotably coupled to the rearward portion of the frames. Sets of pedals operatively engage the forward wheels to provide power, braking and turning operations to the velocipede.

A torsional vibration damper housing includes four or more components that are attached to one another utilizing a high intensity welding procedure. In particular, the housing includes a circular hub portion cut or machined from a flat plate. Attached to the hub portion is an inner hollow cylinder that is preferably cut to length from available tube stock. A pair of circular flat plates are attached to, and extend radially away from, the inner hollow cylinder. Finally, an outer hollow cylinder, which is also preferably cut to length from available tube stock, is attached adjacent the outer edges of the circular flat plates to define a housing having a sealed annular chamber with a rectangular cross section. The multi-component structure allows for the use of a ring mass having a nearly rectangular cross section and the use of relatively thinner walled housing components.

An automatic closing spout for a combine grain auger which opens when there is grain passing through the auger comprising a pivotally mounted collecting bucket attached adjacent the discharge opening of the auger with counterweighted arms extending outwardly from the collecting bucket to hold the bucket in a closed position, but insufficient when the bucket is full of grain from dumping and allowing grain to discharge from the auger housing and including a secondary closing means in the form of a permanent magnet which holds the collecting bucket in its closed position to prevent premature discharge therefrom.
