Abstract: A coupler interconnects adjacent sections of soil nails to extend the lengths of the nails. The coupler includes projections extending from the exterior surface of the coupler. The projections serve multiple purposes. One purpose is to center the soil nail within a drilled hole. Another purpose is to provide mixing for amounts of drilled material to remain within the hole, and/or evacuation of drilled material to be removed from the hole. Another purpose is to create a drilled hole with varying diameters in response to different geological layers encountered during drilling. The coupler may include a plurality of ports or openings formed in the body of the coupler enabling injected material such as grout to be further mixed by the rotating action of the coupler during use. The invention further includes a soil nail assembly and a method for installing a soil nail assembly including couplers with projections.

Abstract: A coupler interconnects adjacent sections of soil nail members to extend a length for a soil nail to be installed. The coupler includes a plurality of projections extending from the exterior surface of the coupler. The projections serve multiple purposes. One purpose is to center the soil nail within a drilled hole. Another purpose is to provide mixing for selected amounts of drilled material to remain within the hole, and/or evacuation of drilled material to be removed from the hole. Another purpose is to create a drilled hole with varying diameters in response to different geological layers encountered during drilling. The coupler with projections therefore serves as a secondary drill bit implement. The size of the projections can be altered to selectively enlarge a desired portion of a drilled hole. The invention further includes a soil nail assembly and a method for installing a soil nail assembly including couplers with projections.

Abstract: An OBD2 device (safety device) monitors vehicle information such as vehicle speed, which vehicle information is electronically publishes and subscribed to by a safety monitoring application on a mobile communication device. The safety monitoring application determines when predetermined vehicle motion criteria have been meet and requests that the OBD2 device send a human interface device (HID) keyboard command to the mobile communication device, where the HID keyboard command is a screen lock command. The OBD2 device send the HID keyboard command to the mobile communication device which locks the screen of the mobile device.

Abstract: A power supply configured to emulate the functionality of ignition-switched power in a vehicle is configured to plug into an on-board diagnostics port (OBD-II) in the vehicle. The power supply includes a controller that is configured to determine the operating protocol to use and then communicates queries based on the determined protocol to obtain the current values for the engine speed and vehicle speed. The controller compares the current values against predetermined thresholds to determine whether the vehicle operating state is in an ignition-on state. When in the ignition-on state, the controller asserts an enable control signal, which is provided to a switch that responds by switching the un-switched vehicle battery from the OBD-II port to an output interface of the power supply. When the controller determines that the vehicle is no longer in an ignition-on state, the controller de-asserts the enable control signal, thereby removing the power from the output interface.

Abstract: The three dimensional audio system may have an audio terminal and a computer input terminal in communication with multiple routing relays. The routing relays may be in communication with a volume calibration control that may be in communication with a volume control and a mute switch. The output of the volume control and the mute switch may be communicated to a variable compressor. The variable compressor may be in serial communication with a digital delay element, a first equalizer and a first variable crossover. The variable crossover may be in serial communication with a second delay element and a second equalizer and in communication with a frequency balance and mix element. The second equalizer may be in serial communication with a frequency balance and mix element that is in serial communication with a phase adjustment element and an output terminal. There may be front and rear elevated speakers.

Abstract: An apparatus and a process for growing a silicon epitaxial layer on a main surface of a silicon substrate wafer are disclosed. The apparatus and process provide a reactor and a gas feeder system. The gas feeder system utilizes an auxiliary dopant supply mass flow control (MFC) to provide an auxiliary dopant only into a central injector that effects epitaxial deposition on the center of the wafer for autodoping correction. An auxiliary bellows metering valve is provided between the auxiliary MFC and the center injector to absorb pressure variations in the central flow line to prevent the pressure variations from reaching the auxiliary MFC. This results in a stable and consistent dopant concentration and resistivity profile.

Abstract: In a digital switching network system wherein service measurements are periodically automatically collected, a user interfaces with the network via a Web browser to select those traffic counts of interest for on-demand sampling. The user designates whether the selected traffic counts are retrieved as a single sample or as a periodic sample. When the traffic counts are to be retrieved as a periodic sample, the user designates a period for the periodic sample. The system determines the locations where the traffic counts resides in the network, retrieves the traffic counts from their locations, and displays the traffic counts to the user.
