Patent CA-2455699-C (CA)
Title: Connector
Inventor: CAMPAU DANIEL N
IPC: F16L37/138
Filed: 2004-01-23
Granted: 2007-12-04
Abstract: The present invention is directed to a connector, comprising a first connector segment having a laterally extending flange, and a second connector segment having a body and a pair of opposed retainers adapted to releaseably maintain the first and second connector segments in mated relationship. Each of the retainers has a lever spaced laterally from the second connector segment body, the lever being joined to the second connector segment, body at a base end and having a latch at a free end. The lever is also joined to the second connector segment body by a fulcrum wall positioned intermediate the ends of the lever, an outwardly facing cam surface is provided on the lever between the fulcrum wall and the base end. A slide ring is disposed over the second connector segment retainers, the slide ring being moveable from a first position adjacent the latch of each retainer to a second position of engagement with the cam surface of each retainer. The latch of each retainer is engageable with the flange of the first connector segment to prevent uncoupling of the first and second connector segments. The latches of each retainer are locked in engagement with the first connector segment flange when the slide ring is in the first position, and the latches of each retainer are disengaged from the first connector segment flange to thereby permit uncoupling of the connector segments when the slide ring is in the second position.

Title: Simplified deallocation of memory for programming objects
Inventor: LARI MOHAMMED SHOAIB
IPC: G06F12/02
Filed: 2003-04-28
Granted: 2012-08-07
Abstract: A method for providing memory management for objects is described.  Specifically, techniques are described for providing common memory management code to objects that are instances of different classes and for releasing a memory management subtree that starts with a particular object in the memory management tree. A memory management template provides common pre-processor memory management code. A specialized version of the memory management template is used to create a specialized template subclass. When a memory management operator of an object that is an instance of the specialized template subclass is invoked the common memory management code in the specialized template is executed. Memory is associated with each object in a hierarchical tree. Data for the memory is maintained that reflects the hierarchical tree relationship between the objects. A subtree and the associated memory can be released without an application program tracking the relationships.

Granted: 2009-07-14
Abstract: The invention relates to a method for producing electrochromic devices, in particular that having a large working surface area and which does not produce a volumetric shrinkage and can operate during a long maintenance of electrocoloured state of an electrochromic compound, high control voltages and polarity inversion. The inventive electrochromic device comprises at least two electrodes (1, 2), at least one of them being optically transparent. A closed sealed space is formed between said electrodes and filled with the electrochromic compound which is embodied in the form of a solid-like film.  The inventive method for producing the electrochromic device consists in prefabricating an initial electrochromic compound in the form of a dispersed electrochromic system which contains at least a suspension and/or colloid. The dispersed medium of said system is embodied in the form of an electrochromic solution containing a liquid solvent, cathode and anode components, a dispersed phase being embodied in the form of a finely dispersed polymer.  Afterwards, the initial electrochromic compound is deaerated, thereby eliminating dissolved oxygen and air introduced by said finely dispersed polymer, and is used for filling the space between the electrodes.

Abstract: An apparatus, system, and method are described for multi-carrier communication using adaptive tone-pruning. The method may include transmitting a data-bearing signal over a plurality of tones on a communication loop within a plurality of communication loops and calculating a minimum tone cost according to a tone cost algorithm. The tone cost algorithm defines a tone cost associated with a selected tone within the plurality of tones. The tone cost of the selected tone is based on a predefined loading frequency and a signal-to-noise ratio (SNR) of the selected tone. The method also may include determining a bit loading pattern for the data-bearing signal according to the minimum tone cost. This determination may occur in response to a determination that a minimum allowable transmission power is greater than a minimum required transmission power for the data-bearing signal.
