| 20100084471 | DEVICE AND SYSTEM FOR PROCESSING IMAGE DATA REPRESENTING BAR CODES - A device for processing image data relating to bar codes is described. In one embodiment a bar code verification device is provided having an ergonomic form factor characterized by a domed hand held trigger and a viewing window. The verification device may be disposed in a network that includes a host processor system and other bar code reading devices which may include other bar code verification devices. Processing circuitry for processing image signals corresponding to printed bar codes may be partially disposed within the hand held verification device and partially disposed within a host processor system spaced apart from and associated with the hand held verification device. The hand held verification device may be in wireless communication with the host processor system to which it is associated. The bar code verification system may include signal enhancement modules which interpolate constructed pixel values from actual pixel values and which correct for signal degradation resulting from high frequency spatial sampling. | 04-08-2010 |

| 20110044910 | IN VIVO FLOW CYTOMETRY BASED ON CELLULAR AUTOFLUORESCENCE - The present invention generally provides methods and systems for performing in vivo flow cytometry by using blood vessels as flow chambers through which flowing cells can be monitored in a live subject in vivo without the need for withdrawing a blood sample. In some embodiments, one or more blood vessels are illuminated with radiation so as to cause a multi-photon excitation of an exogenous fluorophore that was previously introduced into the subject to label one or more cell types of interest. In some other embodiments, rather than utilizing an exogenous fluorophore, endogenous (intrinsic) cellular fluorescence can be employed for in vivo flow cytometry. The emission of fluorescence radiation from such fluorophores in response to the excitation can be detected and analyzed to obtain information regarding a cell type of interest. | 02-24-2011 |

| 20090006056 | CLOSED-LOOP CABIN PRESSURE CONTROL SYSTEM TEST METHOD WITH ACTUAL PRESSURE FEEDBACK - Testing of an aircraft pressure control system may be performed without use of an altitude chamber. Aircraft cabin configuration date may be modeled and used, along with high resolution positional feedback from a simulated valve, to produce a high resolution electrical signal that may represent a simulated cabin pressure. A voltage-to-pressure transducer may convert the electrical signal to a pneumatic signal. The pneumatic signal may be employed to operate a cabin-pressure controller under test. The controller may operate an outflow valve actuator and an attached potentiometer. The potentiometer may produce a feedback signal and closed-loop testing of the aircraft pressure control system may thus be performed. The outflow valve actuator may be operated without being attached to an outflow valve because a simulated aerodynamic load may be applied to the actuator. | 01-01-2009 |
