The present invention is an improved compound bow. In particular, the present invention is directed to an adjustable compound bow for hunting and archery with noise reduction features. The preferred embodiment of the bow comprises a riser having a main riser length with two ends, each end attached to an adjustable hub with a limb base. Each limb base preferably has a pocketless flat surface with vibration dampening material. Each hub is secured to the main riser length by an adjustment worm drive and a hub pivot. A limb is preferably secured to each limb base at two points on the pocketless flat surface. A bowstring is strung under tension between the limbs. The bowstring's tension can be adjusted by adjusting the adjustable hubs with the worm drives. The bow preferably has a storage position and an in-use position caused by rotating the limbs around the adjustable hubs. Adjustment of the bow can be accomplished without use of a bow press.

There is described a novel apparatus for use in connection with pipe cleaning and monitoring systems. The apparatus is a suspension system adapted to fit a pipeline pig shaft, the pig being provided with a plurality of wheels. The wheels are concentrically mounted around a biasing means which is operable in a direction coplanar with the pig shaft. There is also described a pipeline pig comprising the suspension system and a method of cleaning a pipeline.

An interface is provided for storing microfluidic samples in a nanoliter sample chip. A fluid access structure provides a fluid access region to a selected subset of sample wells from an array of sample wells. A fluid introduction mechanism introduces a sample fluid to the fluid access region so that the sample wells in the selected subset are populated with the sample fluid without the unselected sample wells being populated with the sample fluid.

The present invention involves several different embodiments related to a crossover switching valve. The crossover switching valve is preferably designed to receive fluid from a reservoir, or other fluid source, and direct the inflow and outflow of the fluid between the valve and one or more pumps. In one embodiment, the valve is configured to provide a substantially continuous flow rate when used in connection with a double acting pump. In another embodiment, the valve preferably includes an inflow port, an outflow port, and first and second ports configured to be fluidly connected to at least one pump. Another embodiment of the present invention is at least one conduit that preferably provides fluid communication between the first and second ports. Yet another embodiment is a fluid director that is preferably configured to alter flow of fluid through the conduit. Also disclosed is a pumping system that incorporates the crossover switching valve and a pump.

A system and method are provided in which each reader may conduct concurrent, yet independent, dialog with multiple tags at the same time using two or more phase channels. The reader itself may communicate with multiple tags via the same antenna, or using multiple antennae where each antenna operates on a separate phase channel. Upon receipt from the reader of an instruction for the tags to randomize, the tags randomly choose and assign a phase channel that will be their time reference for subsequent operation, or the channel can be assigned by the reader. The tags receive reader data encoded in the clock signal from the reader, and select the reader data pertaining to the particular tag based on the selected phase channel.

A toy comprising a host structure, a plurality of attachable items which can be selectively attached to the host structure, and a radio frequency identification device. The radio frequency identification device comprises at least one reader and a plurality of tags which, when read by a reader, provide identification information particular to that tag. Each reader is housed by the host structure and the tags are each housed by one of the plurality of attachable items. The reader reads the identification information from a particular tag when the corresponding attachable item is attached to the host structure and a different output is generated depending upon which item has been attached.

A fuel mixture dial for use with a fuel container. The fuel mixture dial having a first body member and a second body member adjacent to another. The dial having a third body member adjacent to the second body member. A fastener extending through all body members. The body members all rotate relative to one another.
摘要:
A system for monitoring operation and location of a movable entity, such as a person, vehicle, movable equipment item or movable structure, at an activity site, such as a construction or mining site, that carries a location determination (LD) signal module to determine the entity's present location. When a restricted or hazardous activity occurs without warning (emergency) or is scheduled to occur at a selected location (fixed or moving) and selected time interval on the site, a buffer zone surrounding the restricted activity location is determined, and any movable entity that is within or will come within the buffer zone is advised to move or be moved elsewhere during the time the restricted activity occurs, unless the movable entity has an associated priority that is greater than an associated priority for the restricted activity. The buffer zone may vary with time in size, location and other characteristics. Complex buffer zones, resulting from overlap of two or more activated buffer zones, can also be created and monitored. Signals can be received by the LD module from sources such as GPS, GLONASS and LEO satellites, or from ground-based signal sources such as Loran signal towers.

A non-linear network is disclosed for use in a power processor (converter) for limiting transformer primary winding current during (switching) transitions of a transformer driving potential, the network employing a resistor for coupling a suitably limited current from the potential to the winding and a saturable reactor connected in parallel with the resistor, the reactor for bypassing the resistor except during (and until a suitable period after) transitions of the potential level.

Systems and methods for an identification capable communication device are provided. The communication device or line is registered or associated with a primary unique ID that identifies a person. Furthermore, the unique ID is associated with a secondary unique ID (e.g., biometric information of that person, or a unique identification code only known by that person). The combination of the primary and the secondary IDs is registered with a server system that is capable of verifying the two IDs when a communication connection is initiated from the registered communication device or line.
