Abstract: A control valve assembly for a variable cam timing phaser includes a valve housing defining a valve housing interior, a control valve disposed in the valve housing interior, and a weight movably coupled to the valve housing. The valve housing is configured to rotate about an axis during operation of the variable cam timing. The weight is movably coupled to the valve housing and configured to actuate the control valve between a first control valve position adjacent to the first valve housing end and a second control valve position spaced axially from the first control valve position. The weight is configured to actuate the control valve between the first and second control valve positions during rotation of the valve housing about the axis.

Abstract: A variable cam timing phaser of a variable cam timing system includes a housing and a rotor moveable with respect to the housing. The rotor and the housing define advance and retard chambers. The variable cam timing phaser also includes a control valve assembly. The control valve assembly includes a valve housing defining a valve housing interior, a supply port, first and second working ports, and an exhaust port. The control valve assembly also includes a piston moveable for controlling flow of the hydraulic fluid through the valve housing interior. The exhaust port is fluidly connectable with a sump through a vent path that is defined by at least one of the valve housing and the rotor. The vent path is configured to prevent air from being sucked into the variable cam timing phaser through the vent path.

Abstract: An amplifier with stacked transconducting cells in “current mode combining” is disclosed herein. In one or more embodiments, a method for operation of a high-voltage signal amplifier comprises inputting, into each transconducting cell of a plurality of transconducting cells, a direct current (DC) supply current (Idc), an alternating current (AC) radio frequency (RF) input current (IRF_IN), and an RF input signal (RFIN). The method further comprises outputting, by each of the transconducting cells of the plurality of transconducting cells, the DC supply current (Idc) and an AC RF output current (IRF_OUT). In one or more embodiments, the transconducting cells are connected together in cascode for the DC supply current, and are connected together in cascade for the AC RF input and output currents.

Abstract: The technologies described herein are generally directed toward using shared radio resources to provide wireless services by multiple mobile network operators. In an embodiment, a method can include receiving a first communication signal via a first wireless provider network and a second communication signal via a second wireless provider network. The method can further include communicating, via first radio spectra shared by the first wireless provider network and the second wireless provider network, the first communication signal and the second communication signal. Further, the method can include receiving a third communication signal via the first wireless provider network and a fourth communication signal via the second wireless provider network.

Abstract: Embodiments of the present disclosure relate to water effect play structures for use in playgrounds, splash pads, and water parks. The play structures comprise a plurality of water tanks maintained at an elevation above a play surface. Each of the plurality of water tanks fills with water and then releases the water contained therein, splashing children in the vicinity. Each of the plurality of water tanks may be configured to release the water contained therein at different times. Further, in some embodiments, the water tanks may be enclosed, such as by being connected to a water transport system that fills the tanks internally and by having a movable cover over the opening(s) through which the water is released.

Abstract: A system and method for non-invasively applying electrical stimulation to target the olfactory bulb and olfactory mucosa. Current is delivered through an optimal montage of electrodes positioned on the lower forehead, nose bridge, and neck posterior for suppressing the progression of disorders or alleviating symptoms caused by olfactory dysfunction such as Alzheimer’s Disease, Parkinson’s Disease, Loss of Consciousness, etc. Electrode placements are proposed depending on application- for instance using only hair free zones for stimulation. This invention was made with government support under Grant R44NS092144 awarded by the National Institutes of Health. The government has certain rights in the invention.

Abstract: One example is a betavoltaic cell that has been fabricated using a semiconductor that includes, but is not limited to, Silicon Carbide (SiC), Silicon (Si), Gallium Arsenide (GaAs), Indium Gallium Arsenide (InGaAs), Gallium Nitide (GaN), Gallium Phosphide (GaP), or Diamond, and uses through wafer via holes or other fabrication techniques to form both positive (+ve) and negative (?ve) contacts on the front and back sides of the cell. In another example, several of these cells with +ve and ?ve contacts on the front and back sides of the cell are arranged vertically and/or horizontally to form customized parallel and/or series combinations that produce a close packed, energy dense betavoltaic composite unit, with increased power outputs relative to a single cell. In another example, tritium or a metal tritide is used as the radioisotope source for the cells.

Abstract: We introduce a new technology for Manufactureable, High Power Density, High Volume Utilization Nuclear Batteries. Betavoltaic batteries are an excellent choice for battery applications which require long life, high power density, or the ability to operate in harsh environments. In order to optimize the performance of betavoltaic batteries for these applications or any other application, it is desirable to maximize the efficiency of beta particle energy conversion into power, while at the same time increasing the power density of an overall device. Various devices and methods to solve the current industry problems and limitations are presented here.
