| 20100072391 | NANO-PARTICLE TRAP USING A MICROPLASMA - A system and method employing a microplasma to electrically charge nano- or micro-particles in a gas phase and, subsequently, trap the charged particles within the microplasma using the microplasma's built-in electric fields are disclosed. Confinement of the particles allows their density to be increased over time such that very low concentrations of particles can be detected, e.g., by methods such as laser scattering and/or detection of the plasma-induced charge on the particles. Preferably, charge detection methods are employed when nano-particles are to be trapped and detected. | 03-25-2010 |
| 20120045863 | MICROPLASMA GENERATOR AND METHODS THEREFOR - A low-temperature, atmospheric-pressure microplasma generator comprises at least one strip of metal on a dielectric substrate. A first end of the strip is connected to a ground plane and the second end of the strip is adjacent to a grounded electrode, with a gap being defined between the second end of the strip and the grounded electrode. High frequency power is supplied to the strip. The frequency is selected so that the length of the strip is an odd integer multiple of ΒΌ of the wavelength traveling on the strip. A microplasma forms in the gap between the second end of the strip and the grounded electrode due to electric fields in that region. A microplasma generator array comprises a plurality of strongly-coupled resonant strips in close proximity to one another. At least one of the strips has an input for high-frequency electrical power. The remaining strips resonate due to coupling from the at least one powered strip. The array can provide a continuous line or ring of plasma. The microplasma generator can be used to alter the surface of a substrate, such as by adding material (deposition), removal of material (etching), or modifying surface chemistry. | 02-23-2012 |

| 20080233655 | Screening For Lysosomal Storage Disease Status - A method of ascertaining the LSD (Lysosomal storage disorder) status of an individual comprising taking a tissue or body fluid sample from the individual and estimating a level in the sample of each of three or more compound indicators. The indicators reflect the level of respectively each of three or more lipid containing storage associated compounds. The levels are used to calculate an LSD index number which is then compared with a standard to provide an assessment of the LSD status of the individual. The indicator compounds are conveniently phospholipids, glycolipids or lipopolysaccharide species measured by mass spectrometry. The method may be used to ascertain the nature of the disorder from which the individual stuffers, and its severity. It may also be used to monitor the progress of treatment and to ascertain the prospects of an individual contracting an LSD by providing a subclinical indicators for the condition. | 09-25-2008 |

| 20110188491 | SYSTEM FOR RAPIDLY ESTABLISHING HUMAN/MACHINE COMMUNICATION LINKS USING PRE-DISTRIBUTED STATIC NETWORK-ADDRESS MAPS IN SIP NETWORKS - A method and system are provided that enhance human/machine communication so as to more closely approximate natural human/human communication by more effectively establishing communications links for human-interactive media. Specifically, the speed and quality of the connection are improved by the method and system, resulting in a more natural user experience. The method includes receiving a Session Initiation Protocol (SIP) call request from an Endpoint (EP). The method determines an external address based on an internal address of the EP uniquely mapped to the external address and pre-distributed to SIP internal routers. The method includes modifying the SIP call request to replace the EP internal address with the EP external address. The method includes forwarding the EP external address to the EP. The method includes establishing a communication link for human-interactive media between the EP and the call provider, the EP using the EP external address, and the communication link not including the SIP Internal Router. | 08-04-2011 |

| 20100181930 | REGULATED POWER SUPPLY - A circuit for producing a regulated output voltage and/or current includes a rectifier to rectify an alternating current (AC) input voltage and current to produce a rectified voltage and current having a frequency. A regulator is coupled to the rectifier to produce a regulated output based on the rectified voltage and/or current. A pair of output terminals supply the regulated output to a load The circuit does not include any capacitors that substantially filter the frequency of the rectified voltage and current. | 07-22-2010 |
| 20100291779 | ELECTRICAL PLUG DEVICE WITH FOLDING BLADES - An electrical plug device includes a housing, support members coupled to the housing and electrically conductive members, each supported by one of the support members. The support members are able to rotate about respective axes so that the electrically conductive members can move between a closed position with the electrically conductive members folded into a trough in the housing and an open position with the electrically conductive members extended out of the housing. An elastic member is coupled to the housing to engage one or more of the support members when the electrically conductive members are in the open position or the closed position. Rotation of the support members from the open or closed positions is inhibited by the engagement of the elastic member and the one or more support members. | 11-18-2010 |
| 20100291786 | INTERFACE BETWEEN CONNECTABLE ELECTRICAL DEVICES - A system for engaging devices having connectable electrical connectors includes a first device and a second device. The first device has a first electrical connector exposed at a first surface that is contoured to define one or more recesses, each of which has a lip. The second device has a second electrical connector exposed at a second surface that is contoured to define one or more gripping elements, each of which fits into one of the recesses to grip one of the lips when the first and second electrical connectors are connected together. The first device also has a movable element that can be positioned such that when the one or more gripping elements are in the one or more recesses and gripping the one or more lips, the movable element blocks the gripping elements from being moved out of the recesses or away from the lips. | 11-18-2010 |

| 20100150520 | METHOD AND SYSTEM FOR CONTROLLING PLAYBACK OF A VIDEO PROGRAM INCLUDING BY PROVIDING VISUAL FEEDBACK OF PROGRAM CONTENT AT A TARGET TIME - In a class of embodiments, a method for controlling playback of a video program by a media player including by providing visual feedback (referred to as a thumbnail) indicative of content of the program at a target location, a media player configured to perform any embodiment of the method, and a computer readable medium which stores code for implementing any embodiment of the method. Preferably at least one thumbnail is displayed and updated in real-time during playback of the program. Typically each thumbnail is a compressed or reduced-scale version of a frame of the program at, or a representative image of a segment of the program including, the target location. Typically, the thumbnail is an element of a displayed timeline control also including a timeline and an icon, position of the icon along the timeline indicates the target location, and the icon is movable along the timeline in response to user selection of different target locations (typically by asserting commands to the media player using a mouse or other input device). Preferably, data determining each thumbnail are computed prior to playback of the program, and the data and the program are stored prior to playback of the program. | 06-17-2010 |
