摘要:
A video compression system compresses video frames comprising pixels defined by n-bit color values. Encoder of video compression system determines the difference between a current pixel value and a plurality reference pixel values. Encoder sends difference value to decoder. Decoder determines current pixel value by adjusting a reference pixel color value by delta value.

The present invention is a supplemental power cell that increases the top-end speed of an RC vehicle and that can be coupled to an existing RC vehicle power supply with minimal cost and effort to a hobby enthusiast. The supplemental power cell includes a rechargeable power cell, preferably a conventional rechargeable nickel cadmium battery, means for coupling the power cell between an RC vehicle power source and an RC vehicle motor and means for removably securing the supplemental power cell to an RC vehicle. The rechargeable power cell includes a cathode and an anode for conducting electrical current. The means for coupling includes a cathode lead connected to the cathode, an anode lead connected to the anode, a first connector that receives the cathode lead, a second connector that receives the anode lead and a tie lead for connecting the first connector to the second connector. The means for securing is preferably a hook and loop fastener having a first portion that is securable to a second portion. The first portion is fixed to the power cell housing and the second portion is fixed to the RC vehicle. In an alternative embodiment, the means for securing is a carriage for receiving and holding the power cell housing. The carriage may be affixed to the RC vehicle by an adhesive.

Integral polymer grids, such as geogrids, are made by stretching and orienting a polypropylene starting sheet material having a defined pattern of holes or depressions in which the polypropylene is at least 50%, and preferably up to about 80%, beta crystals caused by adding a beta nucleating agent to the polypropylene, preferably in concentrations between about 10 ppm to about 100 ppm. Such beta nucleated polypropylene grids exhibit increased yield and break tensile strengths, increased 2% and 5% tensile strengths, increased modulus characteristics, increased torsional stiffness, increased impact strength, and increased grid junction strength. Methods for manufacturing the beta nucleated polypropylene mesh grids are disclosed, along with applications for stabilizing particulate material in civil engineering structures, and the like.
摘要:
A safety electrical receptacle is disclosed which eliminates the danger of accidental shock due to inserting a foreign object into the socket of the described device. The safety electrical receptacle body includes cavities and support structures for positioning rotating cams, fixed electrical sockets with integral electrical contacts and movable resilient spring loaded electrical busses with integral electrical contacts. The contacts remain open and electrically inactive when the receptacle is in the normal unused state with the resilient spring bus displacing the rear cam lobe and positioning the front cam lobe directly into the socket opening. When a plug or other object is inserted into the socket it displaces the front cam lobe and the rear cam lobe moves against the spring loaded electrical bus and closes the contact on the opposite socket. Conversely, when the mating connector plug is removed from the socket the spring loaded electrical bus opens the contacts, repositions the cam in the socket opening and the socket is electrically inactive. The described invention is incorporated within the dimensions of a standard type electrical outlet receptacle and renders the outlet safe, in that no voltage is present at the socket of the receptacle unless the proper mating connector plug is fully inserted into each socket. The cover plate of the safety receptacle has visible markings and power indicator lamps to indicate that it is a safety receptacle. The disclosed safety electrical outlet is designed to mate with and be effective with any standard mating connector, whether equipped with a grounding prong or not. The described invention is designed to be manufactured within currently accepted and approved standard dimensions for electrical outlets and electrical enclosures.

Integral polypropylene oriented nets are made by stretching and orienting a polypropylene starting sheet material having a defined pattern of holes or depressions in which the polypropylene is at least 20%, and preferably up to about 80%, beta crystals caused by adding a beta nucleating agent to the polypropylene, preferably in concentrations between about 10 ppm to about 100 ppm. Such beta nucleated polypropylene nets exhibit increased yield and break tensile strengths, flexural stiffness, modulus characteristics, and crimping retention and resiliency over substantially identical oriented nets made from polypropylene without a beta nucleating agent added. A method for manufacturing the beta nucleated polypropylene oriented net is disclosed, along with a crimped beta nucleated polypropylene oriented net (16) and a sandwich mat product (10) for erosion control which includes the crimped beta nucleated polypropylene oriented net (16) as a layer therein.

摘要:
A method for diagnosing problems with protection of a data source and recovery of the same. The method includes diagnosing a copy of data located at the storage location and diagnosing a temporal version of the copy of data. Based on the diagnosis it is determined whether an error or a warning was detected. If either were detected a response is provided with a suggested solution.
