Left and right perch hangers and grapples (112, 112a) allow perching on various structures, and energy storage (504) and (505) combined with power line (500) and solar (502) energy scavenging circuitry allow extended loiter and mission duration by replenishing onboard energy supplies.

A safe, quiet, easy to control, efficient, and compact aircraft configuration is enabled through the combination of multiple vertical lift rotors, tandem wings, and forward thrust propellers. The vertical lift rotors, in combination with a front and rear wing, permits a balancing of the center of lift with the center of gravity for both vertical and horizontal flight. This wing and multiple rotor system has the ability to tolerate a relatively large variation of the payload weight for hover, transition, or cruise flight while also providing vertical thrust redundancy. The propulsion system uses multiple lift rotors and forward thrust propellers of a small enough size to be shielded from potential blade strike and provide increased perceived and real safety to the passengers. Using multiple independent rotors provides redundancy and the elimination of single point failure modes that can make the vehicle non-operable in flight.

A modular electronic assembly for integration with a pneumatic tire includes a mounting patch, a power source, and at least one electronic device supported by a substrate. The mounting patch is preferably adapted for positioning on the inner liner of a pneumatic tire, and the power source is at least partially embedded in the mounting patch. Such embedded positioning of the battery results in an overall structure with a lower center of gravity than previous tire electronics assemblies, thus having increased mechanical stability and survivability in a tire environment. Electronic device(s) supported on the substrate may receive power from the power source, which in some embodiments corresponds to one or more batteries. The substrate supporting the at least one electronic device may be attached to the mounting patch by a variety of fashions. Exemplary attachment configurations may correspond to an adhesive layer, a hook and loop tape combination, or physical interconnection via terminals extending from the power source through the support substrate. Exemplary electronic devices may include such components as condition-responsive devices including transducers, acoustic devices, sensors, etc. for sensing certain environmental conditions such as temperature and/or pressure, tire revolution counters, vehicle speed sensors, sidewall deflection sensors, tire displacement sensors, microprocessors, memory modules, RFID transponders, light assemblies, data transmitters and/or receivers, and power, supply components. Selected of the electronic devices (including one or more antennas associated with any RF devices) may be encapsulated by a non-conductive rubber or elastic material to facilitate effective transmission characteristics. Conductive springs, flexible conductive elastomer or fatigue-resistance metal may be used to interconnect various electronic components (such as an RF device to an antenna).

The present invention relates to a set of golf club irons in which some of the club heads have a hollow space, and some of the club heads do not have a hollow space. The hollow space is preferably defined by a lower portion of the front face, a portion of the sole, and a rear wall. The presence of the hollow space moves the club head center of gravity back (away from the face) and down (toward the sole), making it easier to get a golf ball airborne. The volumes of the hollow spaces generally transition or get progressively smaller with an increase in the club loft angle, thus altering the center of gravity location and moments of inertia by different amounts for different clubs. The hollow spaces may be empty or filled, in whole or part.

A golf club head includes a body having at least one recessed portion for securely receiving at least one weight member. The weight member includes a lid with a plurality of protrusions respectively received in receiving portions of the recessed portion. At least one of the protrusions has a weight different from those of other protrusions. The lid has a symmetric shape the same as that of the recessed portion of the body, allowing the lid to be mounted in the recessed portion in one of at least two orientations that correspond to at least two different locations of a center of gravity of the golf club head, thereby allowing rapid change in the center of the gravity of the golf club head.

A golf club head that allows a user to customize the location of the center of gravity. The golf club head comprises a club head having a hollow cavity with a weighting port.

The invention provides a simple method, devices and several machines for simultaneously stirring and aerating thousands of vessels or wells of microplates in a robust manner and with economy. This method uses the simple principle of magnetic stirrers being levitated vertically when passed laterally or vertically through a strong horizontal dipole magnetic field. The dipole magnetic fields may be produced by using permanent magnets, electromagnets or a modulating/reversing electro-magnetic field. Each vessel contains a magnetic ball, disc, bar, dowel or other shape (stirrers) which in their magnetic attraction to the dipole magnetic field will cause the stirrers to levitate up in the vessel as the stirrer's magnetic poles attempt to align with the center of the dipole's magnetic field. The stirrers will fall to the bottom of the vessel by gravity or by changing the relative position of the levitating magnetic field to pull them down, or by passing the vessel laterally over another magnetic field. The up and down movement of the stirrers provides a vigorous mixing of the contents of many vessels at same time. If the level of the vessel's meniscus is situated so the stirrers pass through it on their way up and down, the air/liquid interface is significantly increased thereby significantly increasing aeration of the liquid.
