  • Publication number: 20110169942
    Abstract: An inspection system and associated method are provided for inspecting a smoking article having a smokable rod and a filter element serially secured together by a tipping material circumscribing a longitudinal periphery of the filter element and a portion of a longitudinal periphery of the smokable rod adjacent to the filter element. A transport device is configured to transport individual as-formed smoking articles from a first to a second position such that the tipping material associated with each smoking article is accessible at least about the portion of the longitudinal periphery of the smoking article. An inspection device is configured to optically inspect each smoking article, at least about the portion of the longitudinal periphery of the smoking article having the tipping material, as the smoking article is transported between the first and second positions, and to automatically determine from the optical inspection whether the inspected smoking article is defective.

  • Patent number: 7676301
    Abstract: Systems and methods for detecting and analyzing elevated temperatures at a component rack to identify and characterize air recirculation anomalies. In one embodiment, temperatures are sensed in proximity to an air intake of the component rack. Temperature sensors communicate with a workstation having system management software including a thermal management component for analyzing air intake temperatures. Predefined temperature differentials (PTD) are established, corresponding to expected temperature differentials between the selected locations in the absence of any appreciable recirculation. The PTD provides a threshold for comparing with “actual” temperature differentials (ATD) to identify the presence and/or mode of recirculation. If an ATD exceeds a corresponding PTD for a predefined time interval, a signal is output. The mode of recirculation, such as left-side, right-side, or dual-surface recirculation, may be determined using as few as four temperature sensors positioned at a zone of interest (ZOI).

The first connector circuit has a first differential amplifier, a first differential signal path, a first capacitor section capacitively coupling the first differential amplifier to the first differential signal path, and a first DC biasing circuit for imparting a first DC bias to the first differential signal path opposite the first capacitor section. The second connector circuit has a second differential amplifier, a second differential signal path, a second capacitor section capacitively coupling the second differential amplifier to the second differential signal path, and a second DC biasing circuit for imparting a second DC bias to the second differential signal path opposite the second capacitor section having a different magnitude than the first DC bias when the first and second connector are not connected.

  • Patent number: 7610077
    Abstract: The manipulation of RF irradiation to a subject in which a CEST agent has been administered is employed to determine a biological parameter in vivo in conjunction with an MRI imaging process. The exchange rate of the CEST agent is determined through RF manipulation which in turn enables the determination of a biological parameter through standard calibration techniques. The exchange rate of CEST agents is modulated as a function of many biological parameters, such as pH. MRI apparatuses and computer program products configured for determining exchanges rates of CEST agents in vivo are also disclosed.
