Abstract: The present invention features an intelligent sprinkler irrigation system for delivering fluid to an arbitrarily-shaped area in a precise manner. In general, the system comprises (a) a fluid source comprising a pressurized fluid; (b) at least one programmable sprinkler head fluidly connected to the fluid source; and (c) a computer system configured to control the sprinkler head to precisely deliver fluid according to a pre-determined sprinkler function. The computer system comprises a teach mode, wherein a plurality of drive parameters are learned and recorded. These drive parameters function to dictate the specific vector positioning of the sprinkler head during execution of the sprinkler component. The teach mode is further configured to learn and record a plurality of flow parameters, which function to control the fluid delivery component of the sprinkler head (e.g., the valve or nozzle), and more particularly, the manner in which the fluid is delivered or emitted from this component.

Abstract: Metal carnitine chelates comprising carnitine chelated to a nutritionally relevant metal can be used for general nutrition as well as well as to treat a variety of health related problems and symptoms. For example, metal carnitine chelates can be used to maintain good cardiovascular health, increase male fertility, enhance weight loss, provide mineral and/or carnitine supplements for mineral- and/or carnitine-deficient subjects, and reduce alcohol dependency and associated symptoms. Nutritionally relevant metals that can be used include copper, zinc, magnesium, calcium, iron, chromium, and manganese, to name a few.

Abstract: A frictional holding pad removably attaches handheld items, such as a cell phone, to a surface, such as a dash, to allow storage of handheld items on the surface with the pad to prevent the items from shifting or sliding due to the movement of the support surface. A smoother application side of the pad clings to the handheld item by specific or mechanical adhesion, and a contoured exposed side of the pad clings to the surface by specific or mechanical adhesion. The smoother application side of the pad can have a greater surface area than the contoured exposed side so the pad remains with the handheld item when removed from the surface. Indicia can be formed on the pad. The pad can be translucent or transparent. The pad can include an expanded vinyl material or a polyurethane material.

Abstract: A method for recovering valuable chemical products from heavy hydrocarbons such as tar sand or petroleum waste products is disclosed and described. Heavy hydrocarbons can be contacted with a fragmentation fluid which includes ozone and a solvent carrier. The fragmentation fluid can be provided at supercritical conditions. For example, supercritical CO2 can be an effective liquid solvent carrier for ozone. During contact with the fragmentation fluid, the heavy hydrocarbons are reduced in size to form a product mixture of chemical compounds. This product mixture typically includes chemical species which are more suitable than the original heavy hydrocarbons to commercial uses and/or further separation to provide useful starting materials for a wide variety of synthesis and industrial applications.

Abstract: A fluid property measurement system for measuring free stream particulates includes a fluid movement device positioned within a fluid container which is configured to cause fluid flow within the fluid container along a fluid flow path when a fluid is present. A constricted region along the fluid flow path generates a region of concentrated streamlined flow within the constricted region and mixing of the fluid outside of the constricted region. A property measuring device is positioned with respect to the constricted region to measure fluid properties in the region of streamlined flow.

Abstract: A receiver for use in performing open loop MIMO performs parallel interference cancellation to reduce interference caused by other spatial streams. Residual interference within an interference-cancelled signal is mitigated using MMSE filtering. The receiver processes received signals in multiple iterations. On each successive iteration, an MMSE filter assumes a lower interference power level than a previous iteration.

Abstract: A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.

Abstract: A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a stationary permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom within a temperature range which is sufficient to substantially avoid formation of carbon dioxide or non-hydrocarbon leachates. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.

Abstract: A trailer hitch for a vehicle includes an attachment bar and post for attaching the hitch to a vehicle and a base suspended from the attachment post to allow limited lateral movement of the base with respect to the attachment. A universal pivot connector, such as a hitch ball, is mounted on the base to move with the base for mating connection to a tongue of a trailer to be connected to the vehicle. The trailer tongue is biased against rotational movement with respect to the pivot connector whereby the allowed lateral movement of the suspended base and the pivot connector and the resistance to rotational movement of the trailer tongue with respect to the pivot connector combine to move the effective pivot point of the tongue on the universal pivot connector approximately to the center of the rear axle of the towing vehicle to simulate the towing movement of a fifth wheel trailer hitch.

Abstract: Various technologies and techniques are disclosed for providing a numeric tower that represents a structure supporting statically defined numeric data types. The numeric data types each are operable to implement a different but accurate representation of a particular value. Numeric operations are supported for the numeric tower that can be performed with any of the statically defined numeric data types. The numeric tower is extensible, and allows for additional statically defined numeric data types to be added, as well as operations. The numeric tower is also operable to detect overflow situations. For example, suppose a result of an operation will result in an overflow situation because the operation does not fit within a range supported by the particular numeric type. The system converts the numeric type to a different one of the numeric data types when the result does not fit within a range supported by the first one.

Abstract: The Hadamard transform is used to spread data within data blocks in a multicarrier MIMO system, before transmission. In this manner, the negative effects caused by the clustering of bad subcarriers (i.e., subcarriers having a low transmission coefficient due to fading) may be reduced. In at least one embodiment, a MAP-type detection scheme is used in the receiver to extract bit reliabilities from the received signals.

Abstract: Described herein is technology for, among other things, accessing error report information. It involves various techniques and tools for analyzing and interrelating failure data contained in error reports and thereby facilitating developers to more easily and quickly solve programming bugs. Numerous parameters may also be specified for selecting and searching error reports. Several reliability metrics are provided to better track software reliability situations. The reliability metrics facilitate the tracking of the overall situation of failures that happen in the real word by providing metrics based on error reports (e.g., failure occurrence trends, failure distributions across different languages).
