Publication number: 20100310465Abstract: A nanodevice has a containment vessel defining a storage chamber therein and defining at least one port to provide access to and from said storage chamber, and a stopper assembly attached to the containment vessel. The stopper assembly has a blocking unit arranged proximate the at least one port and has a structure suitable to substantially prevent material after being loaded into the storage chamber from being released while the blocking unit is arranged in a blocking configuration. The stopper assembly is responsive to the presence of a predetermined stimulus such that the blocking unit is released in the presence of the predetermined stimulus to allow the material to be released from the storage chamber. The predetermined stimulus is a predetermined catalytic activity that is suitable to at least one of cleave, hydrolyze, oxidize, or reduce a portion of the stopper assembly, and the nanodevice has a maximum dimension of about 1 ?m.Type: ApplicationFiled: July 22, 2010Publication date: December 9, 2010Applicant: The Regents of the University of CaliforniaInventors: Jeffrey I.

Patent number: 7788058Abstract: A mechanism for diagnosing broken scan chains based on leakage light emission is provided. An image capture mechanism detects light emission from leakage current in complementary metal oxide semiconductor (CMOS) devices. The diagnosis mechanism identifies devices with unexpected light emission. An unexpected amount of light emission may indicate that a transistor is turned off when it should be turned on or vice versa. All possible inputs may be tested to determine whether a problem exists with transistors in latches or with transistors in clock buffers. Broken points in the scan chain may then be determined based on the locations of unexpected light emission.Type: GrantFiled: May 6, 2008Date of Patent: August 31, 2010Assignee: International Business Machines CorporationInventors: Peilin Song, Tian Xia, Alan J.

Patent number: 7701270Abstract: Disclosed are design structures for current sink and source circuits, a charge pump, and a phase locked loop. The current sink and source circuits each have a current mirror that biases a transistor connected to an output node. These circuits each further have a two-stage feedback amplifier to sense the current mirror drain voltage and to control the transistor gate voltage in order to stabilize the current mirror drain voltage independent of output voltage at the output node. The amplifier also increases output resistance at the output node. This configuration allows for a wide operation voltage range and ensures good circuit performance under a very low power supply. A charge pump that incorporates these circuits generates highly matched charging and discharging currents. A PLL that incorporates this charge pump exhibits minimal bandwidth shifts and minimal locking speed and jitter performance degradation.Type: GrantFiled: August 27, 2007Date of Patent: April 20, 2010Assignee: International Business Machines CorporationInventors: Stephen D.

Publication number: 20100030187Abstract: A user friendly apparatus and method provides effective pain control resulting from headaches and facial aches, which can be safely used by patients and medical personal alike. The economical apparatus can provide a controller equipped with an injector having a tubular section and nozzle, as well as a nostril-engaging introducer and an optional handle. In the user friendly method, the tubular section of the injector can be inserted through a nostril. The nozzle can then be positioned at an upward angle of inclination in proximity and downwardly and rearwardly of the sphenopalatine ganglion (SPG nerve). Thereafter, an anesthetic can be injected through the nozzle and sprayed upwardly, towards and about the SPG nerve to minimize pain and control a headache or facial ache.Type: ApplicationFiled: August 1, 2008Publication date: February 4, 2010Inventor: Tian XIA
