Abstract: The present invention relates to welding sleeve preferably comprised of a fabric, leather, or leather-like synthetic material. There is an adjustable, secure means for attaching the welding sleeve to the lower arm of a user or to the upper arm of the user depending upon the relative position of the user compared to that of the materials to be welded. In certain preferred embodiments of the present invention, the fabric may be impregnated with or made from a flame retardant material. Multiple welding sleeves may also be used to protect the upper and lower arms of a user.

Abstract: A multiple-stage amplifier includes a driver stage die and a final stage die. The final stage die includes a III-V semiconductor substrate (e.g., a GaN substrate) and a first transistor. The driver stage die includes another type of semiconductor substrate (e.g., a silicon substrate), a second transistor, and one or more secondary circuits that are electrically coupled to a control terminal of the first transistor. A connection (e.g., a wirebond array or other DC-coupled connection) is electrically coupled between an RF signal output terminal of the driver stage die and an RF signal input terminal of the final stage die. The secondary circuit(s) of the driver stage die include a final stage bias circuit and/or a final stage harmonic control circuit, which are electrically connected to the final stage die through various connections.

Abstract: Provided herein is a device (and associated method of using the device) to aid and educate a child in blowing their nose. The device comprises a pinwheel assembly, which is positioned under the child's nostrils such that air expelled from the nostrils will turn the blades of the pinwheel. The device optionally comprises a pacifier, which is configured such that when the nipple of the pacifier is in the child's mouth, the pinwheel assembly is positioned such that air expelled from the child's nostrils will turn the blades of the pinwheel assembly. Other configurations include cups, which encircle the child's mouth, and handles which aid in the proper positioning of the device.

Abstract: An air compressor assembly is disclosed. The air compressor assembly includes a substantially curved frame including a lower frame portion and an upper frame portion, a fluid tank carried by the lower frame portion, a compressor mechanism carried by the lower frame portion, and a storage bin including an engagement mechanism releasably coupled to the upper frame portion.

Abstract: An air compressor includes a housing assembly and a compressor system positioned substantially within the housing assembly. The compressor system is operable to compress ambient air. The air compressor also includes a tank positioned substantially within the housing assembly in communication with the compressor system to receive pressurized air from the compressor system. The tank has a generally flattened spherical shape with a diameter and a width that is less than the diameter. The tank is oriented generally vertically within the housing assembly such that the diameter represents a height of the tank.

Abstract: An apparatus and method for adaptive biasing of a Doherty amplifier (102) is disclosed. The apparatus includes a carrier amplifier (210), a peaking amplifier (214), a carrier amplifier bias circuit (208) and a peaking amplifier bias circuit (212), all integrated onto a single chip. The method includes dividing an input signal into an in-phase signal and a quadrature phase signal. The method further includes sampling the input signal and applying the sampled signal to the biasing circuits. The method further includes adaptively biasing the carrier amplifier and the peaking amplifier by the output of the biasing circuits.

Abstract: A vaccine for in ovo vaccination against avian coccidiosis produced by a method including obtaining the coccidial oocysts from a fecal suspension, homogenizing the fecal suspension, separating the oocysts from the fecal debris by either salt flotation using sodium sulfate or gas flotation using air, sporulating the oocysts using hydrogen peroxide and air sparging, bleaching the sporulated oocysts, washing the bleached oocysts, concentrating the sterile washed oocysts and combining the concentrates of various species of coccidial oocysts, and producing a vaccine. The method in whole or in part can be applied to other kinds of encysted protozoa to produce vaccines for various types of animals.

Abstract: RF power device module (500) having an RF power device chip (206) which integrates an RF power device (208) with at least one of DC detector circuits (201, 202), RF detector circuits (203, 204), and thermal detector circuit (235) which cooperate with optical emitter/detector components (213) that supports a bi-directional optical link (210) made through free space with diagnostic processing and control circuits implemented on a separate chip (214) mounted within the same enclosure (205). The bi-directional optical link (210) enables interpretation of detection signals (227) received from the RF power device chip (206) and the feed back of default or other management and control signals (229) sent back to the RF power device chip (206) in response to the detected and analyzed conditions.

Abstract: A safety mat monitoring system has individual mat indicators associated with corresponding mat switches. A mat switch is activated by pressure on or malfunction of the mat switch. Once activated, an indicator on a controller is activated and, in turn, the controller activates the corresponding individual mat indicator.

Abstract: A method and apparatus is provided for aspiration of all patients, providing both a rigid suction hollow tube and a flexible suction hollow tube. The apparatus also include a ventilation adapter and a detachable tube for suctioning of liquid and particulate matter, such as meconium, and for intubation. Accordingly, oropharyngeal and nasopharyngeal suctioning of fluids and particulate matter is possible, as well as instillation of fluids and suctioning of the lower passageways, esophagus and stomach. The apparatus also includes a projecting appendage forming an oblique angle with the device, as an inlet port for delivery of oxygen or negative pressure and which can also function as a hook for conveniently hanging the device on a nearby edge.
