In certain configurations, a method includes transmitting a first transmit signal from a first transmit port to an antenna port, generating a first coupled signal in response to the first transmit signal using a first directional coupler, providing the first coupled signal to a receive port by way of a first loopback selection switch and a shared back switch, transmitting a second transmit signal from a second transmit port to the antenna port, generating a second coupled signal in response to the second transmit signal using a second directional coupler, and providing the second coupled signal to the receive port by way of a second loopback selection switch and the shared back switch.

Abstract: A method of activating and dewatering sludge through application of acoustic pressure shock waves to wastewater.

Abstract: A method of separating material, such as foam, sludge, oil or grease, at a fluid's surface, by applying acoustic pressure shock waves to the material and the fluid's surface such that acoustic pressure shock waves are propagated in liquid medium of the fluid and in gas medium above the fluid surface.

Abstract: Acoustic pressure shock waves are applied to a membrane in a fluid to prevent attachment of or dislodge biological or solid matter for membrane cleaning or desalination with a membrane.

Abstract: A safety garment ensemble for emergency personnel includes a vest that is configured to position on a torso of a user so that the vest is coupled to the user. The vest comprises ballistic textiles and fire resistant textiles so that the vest is both bullet-resistant and fire-retardant. A first power module, a microprocessor, a plurality of microphones, a plurality of cameras, and a data storage module are coupled to the vest. The microprocessor is operationally coupled to the first power module. The microphones, the cameras, and the data storage module are operationally coupled to the microprocessor. The microphones and the camera are configured to capture audio recordings and video recordings, respectively, of events in an area proximate to the vest. The data storage module is positioned to receive and store the audio and visual recordings.

Abstract: An impact nozzle that atomizes fuel and minimizes liquefication at a supercharger intake manifold comprises a body defining an enclosed channel having proximal and distal ends, a means for attaching a jet to the proximal end, and a pedestal spanning the distal end. An impact pin extending proximally from the pedestal is spaced distally from the distal end of the channel. The impact pin may be mounted to a central longitudinal member having four contoured sides each having a maximum thickness at its distal end and a minimum thickness at its proximal end, the minimum thickness occurring along one of four straight edges that define a rectangular end of the central longitudinal member to which the impact pin is attached, and each border between any two contoured sides forming a sharp contoured edge for evenly dispersing atomized fuel.

Abstract: A computer-implemented method is provided for physical face cloning to generate a synthetic skin. Rather than attempt to reproduce the mechanical properties of biological tissue, an output-oriented approach is utilized that models the synthetic skin as an elastic material with isotropic and homogeneous properties (e.g., silicone rubber). The method includes capturing a plurality of expressive poses from a human subject and generating a computational model based on one or more material parameters of a material. In one embodiment, the computational model is a compressible neo-Hookean material model configured to simulate deformation behavior of the synthetic skin. The method further includes optimizing a shape geometry of the synthetic skin based on the computational model and the captured expressive poses. An optimization process is provided that varies the thickness of the synthetic skin based on a minimization of an elastic energy with respect to rest state positions of the synthetic skin.

Abstract: Various aspects of the present invention provide compositions and implantable devices including a water-insoluble therapeutic agent solubilized in a matrix of a gallate-containing compound. Other aspects provide methods of manufacturing and using such compositions and devices.

Abstract: Apparatus and methods for front-end systems with multiple loopbacks and a shared back switch are provided. In certain configurations, a front-end system includes a first transmit path between a first transmit port and an antenna port, a second transmit path between a second transmit port and the antenna port, a first loopback path from the first transmit path to a receive port, and a second loopback path from the second transmit path to the receive port. The first and second loopback paths operate with a shared back switch to reduce area and/or complexity of the front-end system. Additionally, each loopback path includes a loopback selection switch that operates in combination with the back switch to select that particular loopback path.

Abstract: A swivel shelving system is provided. The swivel shelving system includes a mounting bracket coupled to a corner between a wall and a window, a support arm rotatably coupled to the mounting bracket, and a shelving assembly rotatably coupled to the support arm. The shelving assembly is rotatable between a first position adjacent a window and a second position adjacent a wall. Further, the shelving assembly may include a vertical support coupled directly to the shelf and in other embodiments, the shelving assembly may be a vertical support coupled to a shelf support and the shelf support coupled to and supporting the shelf.

Abstract: A non-lethal arrow that includes a shaft having a non-lethal arrow assembly on a respective end of the shaft. A nock is connected to an opposite end of the shaft. A plurality of vanes is connected to the shaft near the nock. A marker can be attached to an end of the non-lethal arrow assembly that is configured to stick to a target upon impact with the target. The marker is further configured such that the non-lethal arrow disengages from the marker, and falls away from the target upon impact with the target leaving only the marker left on the target.
