Abstract: An antagonistic fluid control system, wherein the system may comprise multiple antagonistic pressure control valves operable with a single actuator, or multiple pressure control valves operable with respective antagonistic actuators. The pressure control valves are configured to provide functional and efficiency advantages, and operate together to provide several operating or valving states. A first valving state comprises an active valving state configured to actively control the movement of the load. A second valving state comprises an inactive actuation state, wherein either the return and pressure ports of one pressure control valve are closed, or only the return ports of one pressure control valve are opened, to allow the other pressure control valve to operate in an active valving state. A third valving state comprises a passive valving state, wherein the pressure control valves are operated in a slosh mode configured to allow the load to freely move or dangle.

Abstract: A system and method for embedding a written signature into a secure electronic document is disclosed. The method includes forming a placeholder electronic document containing content to be attested to by a signature. A signing individual can be selected from a signer list. A signature tag can be placed into the placeholder electronic document at a selected signature location. The signature tag is associated with the signing individual and defines the signature location for the signing individual to sign. The placeholder electronic document can be secured to form a secure electronic document having content configured to be uneditable. A signature can be captured with a signature capture device configured to enable the signing individual to write the signature to be embedded into the secure electronic document at the location indicated by the signature tag to mimic a real world experience of signing paper documents.

Abstract: A golf putter head comprises a putter head, operable to be attached at or near an end of a putter shaft. The putter head includes an attachment interface for attachment to the putter shaft, the attachment interface defining a shaft axis with which the shaft is aligned when attached to the putter head. A front face is suitable to strike a golf ball and a rear face is oriented opposite the front face. The rear face includes a spine support, coupled to or formed integrally therewith, the spine support having a substantially continuous curvature. The spine support gradually decreases in depth, relative to the front face, across the rear face in directions orthogonal to the putter shaft axis.

Abstract: A road and rail vehicle includes a towing vehicle having a plurality of axles coupled to an elongate frame with road wheels disposed on the axles. The plurality of axles include at least one rear drive axle. Rail guide wheels are movably coupled to the frame. The rail guide wheels are movable between a lowered position engageable with a pair of fixed rails of a railroad track and a raised position away from the rails. A crane is coupled to the frame rearward of a rearmost road wheel. A tag axle is pivotally coupled to the frame rearward of the crane. The tag axle pivots between a lowered position that is engageable with a roadway and a raised position adjacent the crane.

Abstract: A shower drain adapter configured to allow use of a bondable waterproof membrane with a shower pan drain system comprises a drain body and a lower mating flange extending from the drain body. The lower mating flange is operable to mate with an upper portion of a body of a shower pan drain installable on a waste pipe. An integrated bonding flange extends from the drain body and is operable to be sealably attached to a bondable waterproof membrane to provide a waterproof seal between the membrane and the adapter.

Abstract: An embodiment of the present invention provides a method of quick access channel information loading in wireless networks, comprising mapping at least one quick access channel to one distributed resource unit of control tiles, said control tiles being spread across consecutive sub-carriers and consecutive OFDMA symbols, wherein each control tile and a predetermined number of sub carriers are used to send a bandwidth indicator and a predetermined number of sub carriers are used to send a bandwidth request message, and wherein there exist unique orthogonal sequences for the bandwidth indicator and each of the sequences are capable of being selected as a preamble sequence.

Abstract: A 4-Terminal JFET includes a substrate having a first conduction type and an upper layer having a second, opposite, conduction type over the substrate. A gate and a source are embedded in the upper layer. A gate pad is electrically connected to the gate. A region, which has a first conduction type, is formed in the upper layer and separates the upper layer into two sections. This region reduces the overall capacitance between the gate pad and the source. Reduced overall gate to source capacitance can result in reduced noise amplification in the JFET.

Abstract: A wearable, self-deploying fall arrest device to resist sliding movement of a climber on a climbing surface includes a pick blade pivotable between a retracted position and a deployed position. A tip of an out-turned tooth on the pick blade can be oriented downwardly and outwardly in the retracted position to engage and catch the climbing surface. An out-turned fin can be disposed on the opposite end of the pick blade above the pivot to urge the pick blade out of the retracted position upon pressing the fin against the climbing surface.

Abstract: Methods and devices for a miniature, ultra-low power impact recorder for detecting, quantifying and recording the energy of an explosive blast or ballistic projectile impact. In one embodiment, the impact recorder can included a sensor comprised of an array of electromechanical resonators that is sensitive to the vibrations produced in selected, discrete frequency ranges that approximate the spectral signature characteristics of the shockwave resulting from the ballistic impact event, even after traveling through impacted material or body tissues.

Abstract: A fluid control or actuation system providing selective recruiting of actuators antagonistic to one another to provide variable output power, such as that used to drive a load. The actuators are intended to comprise different sizes, and to be operable with one or more pressure control valves capable of providing displacement of a non-recruited actuator without requiring active input to cause such displacement. Being able to selectively recruit different sized actuators to drive the load, and being able to displace non-recruited without active input, effectively incorporates a gearing function into the fluid control system.

Abstract: Contoured solid polycrystalline superabrasive material such as twist drill tips and endmill flank segments can be formed by preparing a precursor mold having a plurality of shaped openings each corresponding to a predetermined shape. A specially prepared charge feed can be placed into the shaped openings to form a charged precursor. The charge feed can include a substantially homogeneous mixture of superabrasive source particulates, sintering binder, and optional inorganic bonding medium. A loaded reaction cup-assembly including the charged precursor can be subjected to a pressure, temperature and time sufficient for sintering and formation of the contoured polycrystalline superabrasive material. Reduced finishing steps and increased tailorability of grade and quality of final polycrystalline products can be readily achieved.

Abstract: A system and method are provided for informing business management personnel of business risk. The method can include the operation of defining a plurality of business risk rules that are tied to specific risk events and information.

A query can be made of whether predicate risk rules in a section of data points are satisfied using the predicate risk rule in a core data point. The core risk rules for the core data points can be applied after predicate risk rules for the core risk rule have been satisfied. A further operation is displaying a graphic icon to an end user for core risk rule status representing whether a core risk rule has been satisfied.
