US Patent:

6480584, Nov 12, 2002

Filed:

Jun 28, 2001

Appl. No.:

09/894051

Inventors:

Joe W. Duran - Austin TX
Michael Vayden Jenkins - Austin TX
William Todd Clayton - Austin TX

Assignee:

Forgent Networks, Inc. - Austin TX

International Classification:

H04M 1100

US Classification:

379 9321, 37920201, 348 1408

Abstract:

A teleconferencing system with capability to store incoming multiple medium messages for later retrieval and playback is disclosed. The system includes a communications multiplexer which, in normal mode, receives the incoming message and routes the message to various output functions, including video, audio, and computer display. In store mode, the communications multiplexer receives the incoming message and communicates it to disk storage, for example by way of direct memory access. During playback, the communications multiplexer receives data from the disk storage, and controls its communication to the various output functions, in the same manner as during receipt of a normal incoming message during an interactive teleconference. As a result, multiple medium messages may be stored for later retrieval, with the playback appearing in the same manner as a conventional teleconference message.

Appl. No.:

10/703236

Inventors:

Michael Braun - Oconomowoc WI, US
Michael Jenkins - Slinger WI, US
Gregory Kruepke - Waukesha WI, US

Assignee:

Wacker Corporation - Menomonee Falls WI

International Classification:

E01C 1922

US Classification:

404112

Abstract:

A control module for a walk behind trowel configured to detect and to prevent an uncontrolled or undesirable motion of the trowel. The trowel includes an engine configured to drive rotation of a rotor. The control module includes a gyroscope and a controller. The gyroscope is configured to provide an electrical signal representative of an angular rate of motion of a reference structure on the walk behind trowel. The controller is configured to receive the electrical signal from the gyroscope and to determine when a change in the angular rate of motion of the trowel exceeds a threshold value, and in response, to prevent the engine from driving the rotor to rotate.

Assignee:

Wacker Corporation - Menomonee Falls WI

International Classification:

E01C019/22

US Classification:

404112, 192129 R

Abstract:

A brake of a concrete finishing trowel responds automatically to the cessation of drive torque delivery to the rotor to actively brake the trowel's drive train, hence inhibiting or preventing frame rotation. The brake preferably takes advantages of inherent characteristics of an inclined gear, such as a worm of a gearbox, to permit an internal component of the gearbox to shift automatically upon the cessation of drive torque therethrough from a brake released position to a brake engaged position. In the case of a worm gear-based gearbox, the worm is configured such that reaction forces that are normally generated by the delivery of drive torque therethrough shift the worm to release the brake during normal trowel operation. These forces are eliminated in the absence of drive torque transfer, permitting the worm to shift to a brake engaged position.

Inventors:

Michael Jenkins - Slinger WI, US
Gregory Kruepke - Waukesha WI, US
Michael Ochalek - Mequon WI, US

Assignee:

Wacker Corporation - Menomonee Falls WI

International Classification:

E01C 19/22

US Classification:

4048941

Abstract:

A starter module configured to limit an engine speed of an engine for a walk behind trowel at time of startup. The walk behind trowel includes a rotor driven by the engine, a throttle to command an operating state of the walk behind trowel, and a clutch operable to selectively couple an output of the engine to the rotor. The starter module includes a sensor operable to provide a signal representative of an operating state of the trowel upon engine start-up. The starter module further includes a controller configured to receive the signal representative of the operating state of the walk behind trowel, and to prevent the clutch from engaging the engine output to drive the rotor if the detected operating state is outside of a designated range for idling operation of the engine.

Appl. No.:

11/107401

Inventors:

Michael V. Jenkins - Austin TX, US
Bradley Richard Ree - Austin TX, US

Assignee:

LifeSize Communications, Inc. - Austin TX

International Classification:

H04N 5/235
H04N 1/40
G06K 9/40

US Classification:

348362, 3482211, 348363, 358466, 382274

Abstract:

In some embodiments, images for the video conference may be white balanced and/or exposure controlled. White balancing may include dividing an image's pixels into multiple ranges according to their luminance and chrominance values. In some embodiments, blue and red analog gains may be modified to bring red and blue accumulations closer to green accumulations. In some embodiments, luminance values for an image may be adjusted by increasing or decreasing exposure. The decision whether to increase or decrease the exposure may be made by looking at statistics for luminance values of skin colored regions if there are sufficient skin colored regions on the image. Otherwise, luminance values for the entire image may be analyzed to determine whether to increase or decrease exposure.

Abstract:

Various embodiments of a dual-sensor video camera are disclosed. The dual-sensor video camera includes a color filter array (CFA) sensor, which has a low-pass filter. The dual-sensor video camera also includes a panchromatic sensor. A beam splitter directs an incoming light beam to both sensors. An output image is produced based on image information from the two sensors. The output image includes luminance information based on the image information from the panchromatic sensor and chrominance information based on the image information from the CFA sensor.

Abstract:

In various embodiments, multiple participants (at endpoints) may connect through a video conferencing system. A screen may display other participants in the conference call. For example, multiple participants may be displayed in respective portions of the screen. In some embodiments, each of the participants may use video conferencing systems that support different resolutions. In some embodiments, a transcoder may resolution transcode signals to allow the conference call participants to be displayed on each participant's respective screen at up to the highest possible resolution supported by the respective screen. For example, low resolution video conferencing systems may be displayed on a high definition screen of a high resolution system at the low resolution of the low resolution video conferencing system while another image on the same high definition screen from a different, higher resolution video conferencing system, may be displayed at the higher resolution.
