Abstract: A power tool including a motor and an impact mechanism. The impact mechanism is coupled to the motor and includes a hammer driven by the motor, and an anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer. The power tool also includes a sensor assembly positioned at the nose of the power tool, and an electronic processor. The sensor assembly includes an output position sensor configured to generate an output signal indicative of a position of the hammer or the anvil. The electronic processor is coupled to the output position sensor and to the motor, and is configured to operate the motor based on the output signal from the output position sensor.

Abstract: Disclosed herein are devices and methods for livestock feeding and care. The livestock feeding devices include two horizontal bars adapted to be strung through a hay net, and further include at least two mounting brackets which each include a zigzag channel. One horizontal bar is fixed in place on the mounting brackets, and the other horizontal bar moves in and out of the zigzag channels of the mounting brackets.

Abstract: Methods of sensing a fault in an electronic display may include receiving streaming data to be displayed, appending the streaming data with an animation instruction, displaying the streaming data via a screen, monitoring the animation via a photo-sensor, sensing an interruption in the animation via the photo-sensor, and signaling, in response to the sensing step, a fault in the electronic display. The displaying step may include producing, in response to the animation instruction, an animation in a dedicated area of the screen. In some examples, the sensing and signaling steps may be performed without programmable software.

Abstract: A radial flow reactor vessel is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has internal baskets for confining a bed of active material. The baskets are rigidly supported at both the top and bottom ends of the reactor and have walls that are axially flexible and radially rigid. The vessel has multiple movable support columns designed to facilitate pre-stressing of the baskets to offset axial compressive loads induced from thermal cycling.

Abstract: A radial flow reactor is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has two concentric internal baskets which are rigidly supported at both the top and bottom ends of the reactor. The reactor has a removable section in the inner basket to accommodate rotating arms to dense load one or more layers of active materials between the concentric baskets.

Abstract: A releasable fastener assembly comprises a flexible strap having a plurality of apertures extending through the thickness of the strap and a plurality of grommets positioned in each one of the plurality of apertures. Each of the plurality of grommets comprises a first annular end flange having a substantially flat portion, a second annular end flange, and a generally cylindrical portion that defines a passage. The assembly also comprises a pin having a shaft, a head, and a retractable latching mechanism. The flexible strap is configured to define a loop such that the passages of a first one and a second one of the plurality of grommets are aligned. The pin is selectively insertable through the passages such that the retractable latching mechanism abuts the substantially flat portion of one of the annular flanges when the pin is inserted through the passages of the first and second grommets.

Abstract: A guard is disclosed which aids in protecting animals and/or humans from contacting a body part or clothing on the handle of a bucket which could potentially cause injury. The guard is flexible and relatively puncture and tear resistant. The guard is wrapped around the region of the handle which is attached to the bucket, thereby covering that region. In another version, the handle guard is permanently engaged with the handle prior to attachment of the handle to the bucket. After attachment, the guard can then be positioned and secured directly over an end of the handle, thereby covering that end.

Abstract: A development tool combines advantages of a simulation tool with an object-oriented modeling tool, including a real-time mathematical matrix library and an object model. The tool is applicable to any intelligent control system. A composite object group (COG) contains both sampled-data and event-driven capabilities. COGs merge procedural and object-oriented programming, and provide explicit, graphical integration of both types of processing and are fully hierarchical. A control system is built up of object-oriented components, including these types: atomic, interface, data flow and state transition. A finite state machine (FSM) component is built from states, transitions, events and state transition components. Data flow components provide sampled-data capabilities. FSMs provide event-drive capabilities. Each component may include methods and attributes.

Abstract: The present invention provides systems and methods for producing a shield for protecting an area from a pressure blast. The shield, which attenuates the pressure blast, can be used with tall, mobile, and underwater structures, including structures in densely populated areas. One system includes a source for providing an attenuation material, a delivery system that delivers the attenuation material to nozzles, and at least one valve device to control the delivery. A detector is configured to actuate the valve device to an open position in response to a perceived blast threat so that the delivery system delivers the attenuation material to form the shield proximate to a periphery of the protected area.

Abstract: A composite object group (COG) data structure embodied in a computer-readable medium for building a control system that has both a clock cycle and event processing is provided. An interface for passing information to and from the COG data structure is provided. One or more data flow objects are provided in the COG to accept input data and to produce output data on the clock cycle. The data flow object is connected to the interface and provides sampled-data processing for the control system. One or more state machine objects are provided in the COG; each includes a plurality of states and a plurality of transitions between the states that are each triggered by an event. The state machine object provides event-driven processing for the control system, whereby the COG data structure provides both sampled-data and event-driven processing for the control system.

The tool is applicable to any intelligent control system. A composite object group (COG) contains both sampled-data and event-driven capabilities. Mapping the computing resources of a computing device throughout the hierarchy of a control system is provided for modes, executable programs and threads of a processor. Within a given processor, each component of a control system may be assigned to individual execution threads within that processor simply by naming a thread.
