Alfred A. Wieczorek 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: 7263365
    Abstract: Receiver bandwidth is dynamically altered during operation (with respect to, for example, filter bandwidth and/or filter center frequency) as a function, at least in part, of communication resource allocation.
    Type: Grant
    Filed: April 14, 2003
    Date of Patent: August 28, 2007
    Assignee: Motorola, Inc.
    Inventors: Michael Rudowicz, Alfred Wieczorek
  • Publication number: 20070116308
    Abstract: A mobile station (100) that includes a processor (212) that selectively disables at least one station component to reduce electromagnetic noise generated by the station in the frequency range below 20 kHz when the mobile station is operated in the hearing aid compatible mode. The component can be, for example, a display (204), a light (206) or a wireless interface (208). The processor also can optimize characteristics of audio signals transmitted from the mobile station to the hearing aid for reproduction by the hearing aid. For instance, the processor can selectively adjust filter parameters (216) and/or a signal gain (218) applied to audio signals. A user interface (220) having a soft-key can be provided to cycle through various HAC options.

  • Publication number: 20060013423
    Abstract: The invention concerns a method (200) and system (100) for selectively coupling a communication unit (110) to a hearing enhancement device (112). The method includes the steps of—in the communication unit—selecting (212) between an acoustic coupling setting and an inductive coupling setting, in response to the selecting step, switching (214) an audio output of the communication unit to an acoustic coupling path (136) or an inductive coupling path (138), and outputting (226) through either the acoustic coupling path or the inductive coupling path an audio signal to the hearing enhancement device.

  • Patent number: 6374100
    Abstract: A mobile station (102) contains a local personality database (110) in a memory (306) of the mobile station. The local personality database contains information records (400), at least one of which has a variable personality parameter, such as a directory number (404). The directory number may change with either the time of day, geographic location, or both. At the appropriate time, the mobile station transmits a request to a central office (106) to receive an update of the directory number. The central office searches a parameter database (112) to find the most recent directory number, and returns it to the mobile station, which stores it for use at a later time. The system can also update scan and channel lists in the same manner.

  • Patent number: 6125278
    Abstract: Communication resources are allocated within a radio communication system in anticipation of expected resource requirements using predictions based on information supplied by a subscriber unit. In one embodiment, the system uses the subscriber unit's location history to predict a future location (510, 520, 530). In another embodiment, the system uses radio capability information, along with environment information for the subscriber unit, to predict loading conditions for potential hand-over sites (610, 620, 630), and assigns the subscriber unit to one of the potential hand-over sites based on the predicted loading conditions (640).
