Abstract: A signal pre-processor, for at least partially correcting non-linear performance of a high power amplifier (“HPA”), operates on an over-sampled signal in complex form in the digital domain. By converting the over-sampled signal to amplitude values, the pre-processor is enabled to apply correction values, based on the amplitude values, which correction values incorporate both amplitude and phase correction in respect of distortion generated in the HPA. The use of an over-sampled signal allows out-of-band correction values to be applied to correct out-of-band distortion arising in the signal processing path, for instance in the linearization process itself. The out-of-band distortion can otherwise alias back in-band, creating noise at the HPA.

Abstract: An outerwear garment for wearing by two people at the same time and having four arm sleeves in connection with the garment. The garment may be worn by two people at outdoor events and will function chiefly as a jacket or sweater in order to keep the occupants warm. There are arm sleeves on each end of the garment and two arm sleeves near the middle so that all four arms of the couple can be accommodated by the jacket and all four arms of the occupants can be used external to the jacket.

Abstract: A dental post analog includes an analog post body, and at least one of means for determining the depth of placement of the distal insertion portion, means for gripping the post body, or means for tethering the post body. The analog post body includes a distal insertion portion and a proximal portion that extends beyond the distal insertion portion. The distal insertion portion is configured for temporary insertion into a recess of a tooth, and at least approximately corresponds to the size, shape, and length of a permanent dental post. The post analog may be radiopaque. It may be disposable or autoclavable.

Abstract: The disclosure includes description of a method of noise reduction according to one possible implementation. An audio signal is sampled at a sample rate f. The audio signal is converted to a digital signal in the time domain. For each of a series of frames of time, the digital signal in the time domain is converted to a digital signal in frequency domain for the frame of time. The converting includes determining a set of frequency domain values. The frequency domain values in the set are created by a set of digital filters, and the digital filters are related to each other by a constant ratio of filter bandwidth to center frequency, related to a perceptual scale for audio processing. A set of minimum magnitude frequency domain values is obtained. These values include, at each frequency represented by the frequency domain values, a frequency domain value having a minimum magnitude from among frequency domain values for such frequency over a time interval spanning multiple frames of time.

Abstract: A frame adapted to receive containers, particularly empty plastic beverage containers, such as two-liter plastic pop bottles, and adapted to be attached to a dock structure. When the dock structure, frame and bottles are in mutual cooperation, the containers provide buoyancy to the dock structure. The containers are preferably screwed into the frame and may be removed.

Abstract: A surgical stapling device having a removable staple cartridge is disclosed. The cartridge includes a first opening in the staple-forming end of the housing member to allow access to the a staple and an aligned second opening to allow the lead staple to move therethrough. The staple cartridge also comprises a fixed blocking surface on the housing member and a traveling blocking surface on a feeder shoe. The traveling blocking surface is sized so that the feeder shoe moves relative to the fixed blocking surface while moving the staple. The feeder shoe is further shaped so that, when the trigger member is actuated when no staples remain in the staple cartridge, the staple former is not blocked by the feeder shoe.

Abstract: A railcar is provided with an axle assembly including first and second axle devices that allow one axle device to move relative to the other axle device. In one embodiment, the first axle device is rigidly secured to the platform and the second axle device is pivotally secured to the platform. The second axle device includes terminal ends for supporting conventional hub and wheel assemblies. A plate extends from the axle device and pivotally attaches to the platform. In another embodiment, the present invention is used in connection with a mobile toilet system supported on the upper side of the platform. The platform is relatively rigid to accommodate for the hard plumbing connections of the mobile toilet system.

Abstract: A waste treatment assembly for processing organic waste includes a frame having rails interconnected by a plurality of cross members. A waste treatment system is supported on the frame. A cabin of organic polymer presenting a floor and side walls extends upwardly from and connected to the frame. A metal plate extends over the floor and connects the floor to the frame by sandwiching the floor between the plate and the frame thereby clamping the cabin to the frame. A toilet unit of the waste treatment system is connected to the metal plate. A support interconnects the frame and the metal plate for distributing loads under the toilet unit equally over the floor for preventing the floor from bending under the loads applied thereto.

Abstract: A method of identifying one or more micro-organisms in a fluid comprising the steps of:—

Abstract: Load correction systems and methods. In one embodiment, the load correction system includes an audio source signal and a parametric equalizer coupled to receive the source signal. A summation is configured to combine an inverse of the source signal with an output of the equalizer. An amplifier is configured to receive an output of the summation, and a speaker is coupled to receive an output of the amplifier. According to an embodiment, the equalizer comprises an adjustable equalizer. According to another embodiment, a digital signal processor implements the equalizer and summation. According to yet another embodiment, in absence of the filter, a combination of the speaker and electronic components coupled with the speaker have a larger amount of phase at low frequencies and a smaller amount of phase at high frequencies.

Abstract: Balanced injection molding in a multi-cavity mold of a plurality of ridged-wall products having is accomplished by providing mold parts defining therebetween at least two cavities for forming the ridged-wall plastic products, wherein each of at least two cavities defines a plurality of flow channels in which injected plastic material flows within the cavity and in which flow channels the first side strips are formed; wherein the relative disposition of the mold parts is adjustable for adjusting the dimensions of the flow channels in at least two mold cavities separately so that when plastic material is injected approximately simultaneously into the at least two mold cavities the injected plastic material flows within the at least two cavities at respective flow rates that cause the at least two mold cavities to be completely filled approximately simultaneously with the injected plastic material.

Abstract: A hot runner manifold and a method for making such, comprising a runner, a heating element, a sprue hole defined by said manifold and communicating with said runner at an intersection, said runner, having opposing ends, at least two nozzle drops communicating with the opposing ends of the runner at intersections, all of said intersections describing abrupt changes in direction, a runner insert sealably disposed within the manifold at each point of intersection, said insert defining a toroidal orifice, said insert having one inlet and at least one outlet, said inlet and outlet positioned to enable communication with the runner, and the orifice being free of sharp edges. The insert may be employed to change the level of flow of plastic within said manifold.
