Patents by Inventor Paul A. Flaherty

Paul A. Flaherty has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7184972
    Abstract: A mobile communication system utilizes a mobile two-way communication device such as a cellular telephone, pager, personal digital assistant (PDA), palm-held computing device, and the like, connected to a network. The mobile two-way communication device has a display screen, such as an liquid crystal display (LCD) screen, that is capable of displaying a barcode. The image of a barcode is displayed on the two-way communication device by creating an optical image that can modulate a laser in motion, such as the laser used in a retail barcode scanning device.
    Type: Grant

  • Patent number: 5995253
    Abstract: A variable wavelength transceiver includes a first variable wavelength transmitter, capable of generating an electromagnetic wave of a first wavelength, a second detector of an electromagnetic wave of a second wavelength, and a collision detector coupled to the second detector and the variable wavelength transmitter, the collision detector determining when the energy level of the second detector exceeds a threshold value while the variable wavelength transmitter transmits the electromagnetic wave.
