Abstract: An unmanned aerial vehicle (UAV) is disclosed that includes a retractable payload delivery system. The payload delivery system can lower a payload to the ground using an assembly that secures the payload during descent and releases the payload upon reaching the ground. The assembly can also include a bystander communication module for generating cues for bystander perception. While the assembly securing the payload is being lowered from the UAV, the bystander communication module can generate an avoidance cue indicating that bystanders should avoid interference with the assembly. The assembly also includes sensors that generate data used, at least in part, to determine when the descending assembly is at or near the ground, at which point the assembly releases the payload. The bystander communication module can then cease the avoidance cue and the UAV can retract the assembly.

Abstract: A non-V bank filter for an animal confinement application such as for filtering out the porcine reproductive and respiratory syndrome virus (PRRSV) is provided. The filter may be a deep pleat of synthetic filter media with at least a MERV 14 rating and efficiency sufficient to filter out the PRRSV in high air flow applications. The media may be embossed and have spacers to provide for structural support and open filter structure for airflow. The filter can occupy less space and in some embodiments ½ or even less space than a corresponding V-Bank filter with comparable performance.

Abstract: A shower door assembly includes a first door panel, defining a hole in an upper portion thereof, and a bracket assembly. The bracket assembly includes a bracket having opposing first and second bracket flanges, each bracket flange defining a plurality of corresponding holes at different positions above a bottom end of the bracket flange. The bracket assembly further includes a bushing having opposing first and second bushing flanges, each bushing flange defining a mounting hole. The bracket assembly further includes an axle and a roller. Each bushing flange engages an opposite side of the first door panel and each bracket flange engages a bushing flange. The axle extends through a hole in each bracket flange, a mounting hole in each bushing flange, and the hole in the first door panel. The roller is rotatably coupled to the axle.

Abstract: A shower door assembly includes a header, a door, and an elongated member. The header includes a track and a channel disposed above the track. The door is in moving engagement with the track. The elongated member is received within and slidably coupled to the channel and is configured to be moved within the channel between a first position to allow for removal of the door from the track, and a second position to substantially impede upright movement of the door when the door is moved along the track between an open and a closed position.

Abstract: Methods and apparatuses for correcting errors in a data stream are described herein. In one aspect, the error correction process is operable to correct errors in at least two separate types of data streams, each of which utilizes a distinct error correction scheme. The error correction process utilizes Reed-Solomon code and Error Detection Code (EDC) in combination for error correction. The process comprises using a Reed-Solomon code to identify errors in a plurality of data blocks and attempting to correct the errors. An EDC map is then generated, wherein the EDC map identifies the location of the errors within the corresponding data blocks which includes errors that are not corrected by the Reed-Solomon code.

Abstract: The present invention provides long life optics for a modular, high repetition rate, ultraviolet gas discharge laser systems producing a high repetition rate high power output beam. The invention includes solutions to a surface damage problem discovered by Applicants on CaF2 optics located in high pulse intensity sections of the output beam of prototype laser systems. Embodiments include an enclosed and purged beam path with beam pointing control for beam delivery of billions of output laser pulses. Optical components and modules described herein are capable of controlling ultraviolet laser output pulses with wavelength less than 200 nm with average output pulse intensities greater than 1.75×106 Watts/cm2 and with peak intensity or greater 3.5×106 Watts/cm2 for many billions of pulses as compared to prior art components and modules which failed after only a few minutes in these pulse intensities.

Abstract: An apparatus and method of producing an elongate calibrated extrusion of a formable material. The formable material most suitably comprises a thermoplastics polymer having an outer skin (94) and a foamed core (91). It may be formed using an extrusion apparatus (100) having an extruder (101) and a co-extrusion die (104) which delivers the extrudate between opposed sizing conveyors (106). These travel at a speed suitable to allow them to continuously take up the flowable extrudate. The flowable extrudate is caused to adhere sufficiently to the surface of the sizing conveyers in order to cause the extrudate to maintain its shape. The extrudate is detached from the recirculating sizing conveyors after it has solidified sufficiently to exhibit the desire dimensional accuracy. Produce exemplified includes relatively high Young's Modulus composite product fabricated into materials handling pallets.

Abstract: A cathode ray tube, having a cathode and first, second and third grid electrodes, is biased on to allow an electron current to flow from the cathode to the second grid electrode during a first time period. A first voltage, which is proportional to a sum of gas plus leakage currents flowing in the third grid electrode circuit during the first time period, is applied to a first terminal of a capacitor having first and second terminals. The capacitor is charged to the first voltage by momentarily grounding the second terminal. During a second time period following the first time period, the cathode ray tube is biased off causing cessation of the electron current flow from the cathode to the second grid electrode and of the gas current to the third grid electrode. A second voltage which is proportional to the leakage current flowing in the third grid electrode circuit during the second time period, is applied to the first terminal of the capacitor.
