Abstract: A jetting assembly that can be used to print a high-temperature print material such as a metal or metal alloy, an aqueous ink, or another material, includes an actuator for heating a gas such as a non-volatile gas within a gas cavity. The actuator rapidly heats the gas within the gas cavity, which rapidly increases a volume of the gas, thereby applying a pressure to the print material within an expansion channel that is in fluid communication with the gas cavity. In turn, the print material within the expansion channel applies a pressure to the print material within a nozzle bore, which forces a drop of the print material from a nozzle. The jetting assembly further includes a supply inlet that supplies the print material to the expansion chamber and the nozzle bore, for example, from a reservoir.

Abstract: A method of operating a printer enables activation signals of variable lengths to be generated for operation of a sintering head. The activation signals are generated with reference to a distance between activation signals for a first component to be a first determined distance and a duration of the activation signals for the first component to be longer than the first predetermined distance. This distance and duration are set to values that enable the generation of activation signals before the first predetermined distance is reached to maintain an activation signal until the generation of the activation signals is terminated. By generating a different number of activation signals, the duration of an initial activation signal can be varied.

Abstract: A power supply unit includes a set of primary circuits operably coupled to a set of phase pair electrical inputs. The electrical inputs provide an input voltage via alternating current. Each primary circuit receives a phased pair electrical input of the set of phase pair electrical inputs and provides a tap output. A single transformer is operably coupled to each tap output. A single secondary circuit is operably coupled to the transformer to provide an output voltage via a direct current.

Abstract: A shielding apparatus for mounting on zero-turn type mowers of the variety having a horizontal cross-member forward of an operator seat and disposed between a pair of longitudinal frame members supporting a cutting deck, the shielding apparatus being comprised of a panel having a lower mount portion and an upper shield portion, the mount portion being mountable to the cross-member such that said shield portion is oriented vertically, perpendicular to the cutting deck. The shield portion is sized, shaped and oriented to substantially blocks debris and insects expelled forwardly and upwardly from beneath the cutting deck of the mower from coming into contact with an operator of the mower. Embodiments of the subject shielding apparatus are adapted for magnetic mounting to the mower.

Abstract: Systems and methods are disclosed to verify a program by symbolically enumerating path programs; verifying each path program to determine if the path program is correct or leads to a violation of a correctness property; determining a conflict set from the path program if the path program is proved correct; using the conflict set to avoid enumerating other related path programs that are also correct.

Abstract: A method and system for measuring and compensating for a leakage current in a high voltage transformer. Such a method and/or system include the use of a primary winding and a secondary winding, which can be provided on a core of a soft-magnetic material. A current transformer can be placed about the leads to both the terminals of the primary winding. The current transformer can be utilized to reliably measure the leakage current flowing from the secondary winding to the primary winding through one or more amplifiers to a ground terminal. The leakage current flows back to the transformer secondary winding through a low-side current sense resistor. The total current monitor signal can be generated by the low-side current sense resistor and the leakage current measured by the current transformer is vector-subtracted from the total current monitor signal. The result is a current monitor signal fully representative of the high voltage transformer's actual load current.

Abstract: An article of aquatic apparel including one or more handles. The handles are secured to the apparel and allow for passengers riding along to hold onto the wearer of the article. The handles can be configured as gripping slots or projecting straps.

Abstract: The system and method of the present invention detect bio-hazardous-sized particles in, on, and around mail. The system collects these bio-hazardous-sized particles, tests for the presence of bio-hazardous particles, generates a signal when bio-hazardous particles are detected, and prepares an analysis sample and performs real-time or near real-time analysis and optionally air treatment.

Abstract: A system and method for disseminating information concerning, for example, conditions affecting travel routes personalizes information in accordance with individual users or customers by building filters for attributes of the information from attributes of interest to each user, such as nodes of a travel route, which are registered with the system by the user or customer. The information is filtered by the filters constructed from the attributes to form a list of user identifications of users that have registered an attribute of interest which is included in the information provided to the system. Messages are retrieved from storage and communicated to users in accordance with the list of user identifications either automatically over one or more communication media also registered by each user or on a call-in inquiry basis. In the latter case and for modification or additions to registered user information and attributes of interest, the system and method provide for an active automated dialog with the user.

Abstract: A collapsible and foldable portable valet having upper and lower vertical support members. An upper sleeve is slidable about the upper support member to urge shoulder-lifting arms to extend and support left and right shoulder members and a hanger extension. A lower sleeve is slidable about the lower vertical member to urge legs to extend through a guiding and support brace to stabilize the valet. Channels are provided in the support members to accept the lifting arms and legs to provide a narrow profile and to reduce the space required to store the valet. A second hanger extension is provided to telescopingly extend and collapse within the hollow upper vertical support member. A multiplicity of detent mechanisms lock elements into an extended position. The shoulder members are shaped to provide for full support of a garment hung thereon.

Abstract: A field trailer including a chassis (20) supported by a plurality of wheels (120) having an underlying framework that communicates with the wheels (120) via a swing arm assembly (40) and a vertically disposed wheel plate (80). One wheel plate supports one wheel. Interposed between the swing arm and the wheel plate is a damper (60) that controls the movement of the swing arm (40) about a pivot (28). The structure associated with this support mechanism provides a box-shaped void between the wheels and under the suspension and provides a high clearance free from suspension projections so that produce can run under the trailer when the trailer is used for agricultural transportation from a field to a subsequent area via public roads.
