  • Patent number: 12437942
    Abstract: A DC circuit breaker system includes a first mechanical switch, a first parallel capacitor connecting a first terminal and a second terminal of the first mechanical switch, a second mechanical switch in series with the first mechanical switch, a second parallel capacitor connecting a first terminal and a second terminal of the second mechanical switch, a first diode connecting the first terminal and the second terminal; and a second diode connecting the first terminal and the second terminal. The first mechanical switch separates contacts in response to a fault current; the second mechanical switch separates contacts in response to the fault current; and opening the first and second mechanical switches and turning off the first and second diodes reverses current flow and clears a current fault. The DC circuit breaker system may also be equipped with a surge arrestor at its input and a freewheeling diode at its output.

  • Patent number: 11009934
    Abstract: To eliminate the adverse effects of power swings in a large scale computing system during the life cycle of an application or job, control of several operating characteristics for the collective group of processors is provided. By providing certain levels of coordination for the many processors utilized in large scale computing systems, significant and abrupt changes in power needs can be avoided. In certain circumstances, this may involve limiting the transition between several C-States of the processors involved and the overall power transitions for a large scale system are not detrimental and do not create issues for the data center or local power utility. Some cases will require stepped transitions between C-States, while other cases will include both stepped and modulated transitions. Other cases will incorporate random wait times at the various transitions in order to spread the power consumption involved.

  • Patent number: 10683670
    Abstract: A hand-held tool for spacing clapboards that includes a speed square tongue located in the top center of the device. This feature allows a user to quickly and accurately transfer both horizontal and vertical lines, revealing material to be removed around doors and windows. There is a trigger mounted on the ergonomic handle that both locks the tongue in place for transferring horizontal lines, and releases the tongue for transferring vertical lines. Two trays are adjustable in ΒΌ? increments that use pull pins under the trays. The trays can be adjusted for any board up to 10? in height. Desired overlap is achieved by adjusting the position of the bottom tray as desired. Finally a ruler is provided along the side of the tool. A second model that has no handle is also taught.

  • Patent number: 10554519
    Abstract: In a large scale computing system, a supervisory system is utilized to monitor the operations and requests of multiple components, and to manage such requests so that overall power considerations for the entire system are considered. The supervisory system has the ability to identify requests and aggregations of simultaneous requests that will create an adverse power effect, and to apply overall control methodologies which will help to minimize these adverse effects.

  • Publication number: 20160055250
    Abstract: A computer-implemented method performed by a processor for identifying social media posts relevant to a user, the method including the steps of receiving a first plurality of variable weights from a first user and a second plurality of variable weights from a second user, wherein each variable weight corresponds to a variable of a set of variables, receiving, from a social media feed, a social media post of a social media user, calculating, for the social media post, a first relevancy score using a scoring algorithm with the first plurality of variable weights as an input, calculating, for the social media post, a second relevancy score using a scoring algorithm with the second plurality of variable weights as an input, providing, via a user interface, the first relevancy score to the first user, and the second relevancy score to the second user.

  • Patent number: 8656603
    Abstract: A hand held gauge that contains all of the essential tools a worker needs to install clapboards. The tool is a hand-held device that has a pair of fixed flanges that are relatively long and extend out sideways from the handle for several inches on each end. The flanges are fixed in place. The tool also has the ability to establish proper measurements for window casings and doorframes. This is done by an adjustable gauge that can be extended forward until the casing or frame is reached. One this spacing is obtained; a worker can quickly transfer the measurement to the next piece of clapboard so that it can be cut. The tool includes a level and a tape measure and an optional straight edge for a marking square, so that simple measurements can be made without having to put down the tool and get another tool, which improves productivity.

  • Publication number: 20090093010
    Abstract: Methods and kits for monitoring kidney function, and detecting kidney dysfunction and transplant related disease and rejection are disclosed. The method involves analyzing a sample, such as a urine sample, containing protein from an animal for fragments of ?2-microglobulin, wherein the presence of specific ?2-microglobulin fragments is indicative of kidney dysfunction and transplant rejection. In another embodiement, urine samples from an animal are tested for protease activity, such as cathepsin D or napsin A, wherein increased protease activity compared to a control sample is indicative of kidney dysfunction.

  • Patent number: 7072543
    Abstract: An apparatus for transmission of free space optical communication system signals employing a spatially-extended light source and method of using the same. A laser beam source directs an optical signal into a free end of a segment of multimode fiber. As the optical signal passes through the segment of multimode fiber, the optical signal is converted into a mode-scrambled optical signal. This mode-scrambled signal may then be used as a spatially-extended light source that is directed outward as an optical beam through the use of a collimating lens.

  • Patent number: 6019999
    Abstract: Described is a process for making a liposomal, ion-exchange whey protein and products thereof, which result in the sustained release of amino acids into the body's circulation to generally promote skeletal muscle protein synthesis, decrease body fat in association with diet modification and improve exercise performance. The whey protein is preferably encapsulated in a liposome using a cold, or non-heated, process. After the liposomal, ion-exchange whey protein has been prepared, it is then preferably lyophilized to deliver macronutrients for use as a sports nutrition supplement and for use in medical or clinical catabolic applications.
