    摘要: A probe includes a first rod having a first axis and a second rod having a second axis. A first end of the first rod is connected to a first end of the second rod to form an angle that maintains a “total internal reflection” effect for waves propagating through the probe. A second end of the second rod includes a prong facilitating attachment of the probe to a housing block. The first axis and the second axis define a plane. A second end of the first rod includes a tapered face formed perpendicular to the plane. The tapered face is sufficiently flat to make planar contact with a portion of a component under study. A support is formed in the plane and connected to the second rod. A second end of the support includes a connector to facilitate attachment of the probe to the housing block.

    摘要: There is described herein an active bidirectional tag for use in an RF signaling system for real-time and non-real time localization. The tag has a first antenna that operates at a first frequency and a second antenna that operates at a second frequency. The two antennas allow the tag to perform more than one function concurrently, and to provide different ranges of communication between the two antennas. The tag is low cost, low power, and multi-use.

    摘要: An ambulatory device for measuring urine flow comprises a portable hand-held container and a handgrip mounted thereto. A flow-measuring device is located in the container, and a means for collecting the data measured by the flow-measuring device is also provided. The parameters of the urine flow in the container are measured by the flow-measuring device and are processed by the aforementioned means for collecting data. The handgrip is pivotally mounted to the container by a double-pivot mechanism for maintaining the container substantially vertical in a number of positions of the handgrip. The flow-measuring device includes a sensor that measures a displacement of an air column related to a variation of pressure due to a variation of a urine level in the container.

    摘要: A medical instrument is disclosed. The medical instrument includes a transmission line suitable for the transmission of electromagnetic energy and an antenna coupled to the transmission line. The antenna is configured for generating an electromagnetic field sufficiently strong to cause tissue ablation. The medical instrument further includes a reflector arranged to be electrically coupled to the transmission line. The reflector is positioned laterally to a first side of the antenna and configured for redirecting a portion of the electromagnetic field to a second side of the antenna opposite the reflector, wherein a majority of the electromagnetic field is directed away from the second side of the antenna.

    摘要: A flexible microwave antenna assembly for a surgical ablation instrument is capable of conforming to a tissue surface for ablation thereof. The ablation instrument includes a transmission line having a proximal portion suitable for connection to an electromagnetic energy source, and includes a flexible antenna coupled to the transmission line for radially generating an electric field sufficiently strong to cause tissue ablation. A flexible shield device is coupled to the antenna to substantially shield a surrounding area of the antenna from the electric field radially generated therefrom while permitting a majority of the field to be directed generally in a predetermined direction. A flexible insulator is disposed between the shield device and the antenna to define a window portion enabling the transmission of the directed electric field in the predetermined direction. The antenna, the shield device and the insulator are formed for selective manipulative bending thereof, as a unit, into contact positions that generally conform the window portion to the biological tissue surface to be ablated.
