摘要:
A method and system for characterizing tissue includes a probe connected to a red LASER source and a Raman spectroscope. The probe includes at least excitation fiber and one or more emission fibers that connect the probe with the LASER source and the Raman spectroscope. The excitation fiber is connected to the red LASER source and terminates in the first end of the probe adjacent the tip of the probe. The emission fibers are connected to the Raman spectroscope and terminate in the first end of the probe adjacent the tip of the probe. In one embodiment, the excitation fiber extends through the central portion of the probe and one or more emission fibers are arranged around the excitation fiber. The tip of the probe is intended to come in contact with the tissue to be examined. The tip includes a central opening to allow red LASER radiation to project out of the end of the red excitation fiber on to the tissue and to permit Raman spectra to enter the emission fiber(s) and travel to the Raman spectroscope. The tip is constructed to have a predefined focal length to position the first end of the probe a predefined distance from the surface of the tissue being examined. The tip can be removable and tips having different focal lengths can be used to accommodate different types of tissues and examinations. A detector can convert the Raman spectra into signals and data for analysis by a computer system. The Raman spectra for tissue in a predefined location can be profiled such that the system can distinguish between healthy and diseased tissue.

Near-infrared Raman spectroscopy can be applied to identify preneoplastic lesions of the bronchial tree. Real-time in vivo Raman spectra of lung tissues may be obtained with a fiber optic catheter passed down the instrument channel of a bronchoscope. Using prototype apparatus, preneoplastic lesions were detected with sensitivity and specificity of 96 and 91% respectively. The use of Raman spectroscopy apparatus and methods in conjunction with other bronchoscopy imaging modalities can substantially reduce the number of false positive results.

An automatic discharge device includes a housing having a top portion and a base portion, wherein surfaces defining a recess are provided therebetween for securely holding a container. At least one gear is disposed substantially between the recess and a rear panel of the housing. A drive motor is in association with the at least one gear. An actuator arm is also provided. Activation of the drive motor and the at least one gear provides for movement of the actuator arm between at least one of a pre-actuation position and a discharge position along a path that has a directional component parallel to a longitudinal axis of the recess.
摘要:
An apparatus which facilitates retaining a coil wire from a microphone onto a shirt. The device is used to retain the coil from a microphone to a location adjacent to a police officer's shirt. The microphone or other communication device has an alligator clip or other means by which it is clipped to a shirt. The microphone is attached to a coil which then is attached to a pack which is usually worn on the police officer's belt. The present invention provides a secure loop which is securely retained on the shirt and through which the microphone coil passes. As a result, when the microphone becomes dislodged, the loop provides a means by which the coil dangles from the loop and enables the microphone to remain adjacent to the police officer's shirt.
摘要:
An automatic discharge device comprises a housing adapted to receive a container therein. An actuator arm is attached to the housing and movable between first and second positions. The actuator arm includes a dispensing bore therein. A drive unit is provided for automatically moving the actuator arm into one of the first and second positions in response to a signal from at least one of a timer, a sensor, and a manual switch. The actuator arm is adapted to engage and actuate a nozzle of the container in the first position and allow a fluid disposed in an interior of the container to be dispensed through the nozzle and the dispensing bore of the actuator arm.

摘要:
A method and system for event-driven network management. A network management application is configured to detect a network event generated by an external application and to execute an action in response to detecting said network event, wherein the network management application is configurable to receive information describing the network event and the action. The network event is monitored for. In response to detecting the network event, the action is executed.
摘要:
A side panel for a fabric care appliance is described. The side panel includes an embossed pattern for increasing a first natural frequency (or first harmonic) of the side panel. Preferably, the first natural frequency is substantially higher than any ordinary operating frequency or driving frequency of the appliance. For example, in a washing machine, the first natural frequency of the side panel is preferably at least 1.6 times greater than the maximum rotational frequency of a drum or tumbler of the machine.
