  • Patent number: 10631108
    Abstract: Various systems and methods are disclosed herein to increase the quality of the sound and intelligibility of speech delivered to a user by combining electric audio signals from more than one hearing assistance device that incorporates an active signal enhancement system. The method includes receiving electric audio signals at a first hearing assistance device, and sending electric audio signals to a second hearing assistance device. The electric audio signal is encoded as a replacement for input to an microphone channel located at the second hearing assistance device. The electric audio signals from the microphone located at the first hearing assistance device and the microphone located at the second hearing assistance device are combined. The combined electric audio signals are processed through a digital signal processor in the first hearing assistance device to enhance the amplitude of the desired signal via constructive interference.

  • Patent number: 9164656
    Abstract: A portable, computing device (100) schedules and monitors tasks and their state of completion during a work period. The device includes a touch-responsive graphical display (102). At the start of and during a work period, an operator (400) enters tasks into the device. Task icons (118, etc.) move across the screen at positions representative of the time. A central “bridge” indicator (124) marks the current time. When a task is due, its icon approaches the bridge. If the icon coincides with the bridge, the task is late and a portion of its icon changes color, indicating that the task is late. The display can be scrolled to left and right to enable “looking ahead” and back. The display can also be pinched and spread to reveal in a smaller or larger time-scale the workday contents. The device communicates data and instructions with a remote server (405) wirelessly.

  • Patent number: 5787245
    Abstract: A set of portable services for debugging computer software programs is disclosed. The services provide an object-oriented programming framework which is portable to various hardware and operating system platforms. The framework consists primarily of a debugger server and a debugger client. Multiple debugger clients, which target multiple processes executing on heterogeneous systems, can be used concurrently from a single high-level debugger process. Clients can processes locally and remotely. The client interface is portable to any platform that supports C++. A string class defines storage for variable length character strings.
