  • Patent number: 6942372
    Abstract: A heat dissipating turret for a fiberoptic illuminator includes first turret component composed of a heat conducting material and a second turret component composed of a heat insulating material. The first turret component is releasably interengaged with the front panel of the illuminator and the second turret component is releasably attached to the first turret component. The turret components include respective interior light transmitting channels that communicate when the components are interengaged. The second turret component includes a receptacle for receiving the end fitting of a fiberoptic cable. Light from the illuminator is transmitted through the communicating channels to the fiberoptic cable and the turret components dissipate heat that is generated at the focal point of the illuminator.

  • Publication number: 20040013585
    Abstract: A fluid processing unit having first and second interleaved flow paths in a cross flow configuration is disclosed. The first flow paths are substantially longer than the second flow paths such that the pressure drop in the second flow paths can be maintained at a relatively low level and temperature variations across the second flow paths are reduced. One or more of the flow paths can be microchannels. When used as a vaporizer and/or superheater, the longer first flow paths include an upstream liquid flow portion and a downstream vapor flow portion of enlarged cross sectional area. A substantial pressure drop is maintained through the upstream liquid flow portion for which one or more tortuous flow channels can be utilized. The unit is a thin panel, having a width substantially less its length or height, and is manufactured together with other thin units in a bonded stack of thin metal sheets. The individual units are then separated from the stack after bonding.

  • Patent number: 5835486
    Abstract: A multi-channel transcoder with rate adapter converts the data rate of GSM and PSTN network data in a multi-channel network. A transcoder having echo-cancellation features uses the robust voice activity detection functions of the GSM transcoder functions to enhance the accuracy of echo-cancellation of near-end signals. A method for decoding a GSM signal in which the transmission of the audio data over the network is commenced prior to the completing of the decoding process. A transcoder unit having rate adaption and echo-cancellation with improved decoding is implemented in a single DSP and processes multiple traffic channels simultaneously.
