| 20110157935 | Fully Resonant Power Supply - A power supply produces one or more conditioned and scaled output voltages with low noise. The power supply has various components to produce a plurality of higher output voltages from a plurality of taps of a multiplier or multiple isolated outputs. Components include an internal reference voltage circuit or an external voltage that generates a reference voltage and a sine wave power oscillator circuit and resonant circuit that generates an alternating current and voltage. The power supply has a controlled current source circuit connected to the sine wave power oscillator circuit for regulating the power level to the sine wave power oscillator. A control amplifier circuit controls the current level to the controlled current source circuit based on the error between the sampled output and the reference voltage. The resonant transform connected to the sine wave power oscillator circuit generates one or more scaled output voltages on one or more secondary windings. A buffer voltage feedback circuit is connected to an output voltage and the control amplifier circuit for providing a feedback loop to regulate the output voltage. | 06-30-2011 |

| 20100064621 | Cinder block construction system and method - A cinder block construction system employs a cinder block component with top and side surfaces and cavities extending downwardly from the top surface. Solid body inserts are located in the cavities and are permanently bonded to the cavities' sidewalls. The inserts are composed of material specifically adapted to allow penetration into the body by a connector element. The connector element secures the cinder block component to a construction member such as a sill plate or door or window jamb. The cinder block component can be prepared with its insert in advance, or the insert material dispensed to the cinder block component at the worksite to convert a standard cinder block to one which can readily be connected to a separate construction member. | 03-18-2010 |

| 20110097751 | GLP-1 RECEPTOR AGONIST BIOASSAYS - Provided herein are cell-based bioassays for measuring GLP-I receptor agonist activity of test compounds, such as GLP-I receptor agonist compounds. Exemplary GLP-I receptor agonist compounds include exendins, exendin analogs, GLP-1(7-37), and GLP-1(7-37) analogs. The bioassays are useful for quantitatively determining cAMP generated in samples containing GLP-I receptor agonist compounds (e.g., exenatide) and 6-23 (clone 6) cells having GLP-I receptors, whereby the amount of cAMP generated can be correlated to the GLP-I receptor agonist activity of the GLP-I receptor agonist compounds (e.g., exenatide). Suitable cell-based bioassays include enzyme-linked immunosorbent assays and homogeneous time-resolved fluorescence assays. | 04-28-2011 |

| 20080289639 | MOUTHGUARD - A mouthguard has a flexible frame, and has bite tabs extending from the rear surface of the frame for engaging the wearer's teeth. The bite tabs extending from the rear surface of the frame for engaging the wearer's teeth. A narrow split may be provided between the anterior bite tabs that allows the bite tabs to maintain their flexibility. The flexible frame lays against the outer surface of the teeth and extends into the buccal folds superiorly and interiorly of the cheek where the muscles hold it in place. Grooves may be positioned lengthwise along the frame above and below the bite tabs for purposes of flexibility and to allow the muscles of the check to press the upper and lower extensions of the frame close to the bone for better retention and comfort. The teeth engage the bite tabs, thus preventing the teeth from clashing together and protecting the temporomanibular joint (TMJ). One or more air holes may be provided in the front portion of the mouthguard permitting easy breathing. The mouthguard is retained by the muscles of the lips and cheeks, causes no gag reflex, and is simple, comfortable and protective. | 11-27-2008 |

| 20080240116 | Method and Apparatus for Determining the Locating of Nodes in a Wireless Network - A method and apparatus for determining the relative locations of nodes in a wireless network is disclosed. A list of neighboring nodes of a master node of the wireless network is generated and, from this list, a list of independent nodes is generated. An adjacency table for the independent nodes is then generated by examining the neighbors of dependent nodes. Two independent nodes are determined to be adjacent nodes only if they are the only neighboring nodes of a dependent node. Relative locations of nodes in wireless network may be determined from the adjacency table. | 10-02-2008 |
