Abstract: Transition effects on 3D objects are carried out in a shader of a graphic processing unit.

Abstract: A software touchscreen displayed on start up for a LAN for an automated light. The software touchscreen is displayed by the software on initial startup, and later, after the initial startup, the same touchscreen is used for controlling the light.

Abstract: A remote-control device which allows remotely controlling parameters of a light via a console. The console actually does the controlling, but the remote-control device enables control of the light parameters by sending the information to the console. For example, the remote can be used to control preset values or to control other aspects of the console. The console may store presets associated with focus, and those presets can be changed from the remote.

Abstract: A communication device for use with a power distribution module. The communication device allows multiple different DMX universes to be handled over the same cable that also handles power distribution. A front of house module is provided for powering consoles and receiving DMX inputs from the consoles. Two different consoles can be powered and provide their inputs, and either console can be used to control any or all of the universes.

Abstract: Video buttons controlling stage lights. Each of the buttons includes a video part, which displays either video or an image that previews the function that is carried out by the button when it is pressed. The buttons can be full-color buttons that show full color videos. An array of buttons can be grouped together, so that the array can operate in different modes, one of which in which the array shows an overall display, and another of which in which the array shows a single function per button. Different technologies including analog switches, touch screens, and the like can be used.

Abstract: New effects for controlling digital lights.

Abstract: A digitally controlled lighting system where aspects have a central media server connected to remote media servers. The connection may have separate networks for control versus media. Automatic synchronization of the contents of the media servers may be carried out.

Abstract: An echo canceler is connected to an ISDN Primary Rate Interface. The echo canceler is provided with an activation processor for monitoring call control messages on the D-channel and for selectively enabling or disabling echo cancellation on any of the B-channels in response to information contained within the call control messages. In particular, the activation processor decides whether to enable cancellation depending upon the Information Transfer Capability and Protocol Identification fields of the Bearer Capability portion of a call SETUP message. Additionally, the Channel Identification field of the SETUP message is used to identify the B-channel or channels affected by the SETUP message. When a channel is released, the activation processor maintains enabled echo cancellation as the default condition of the released channel. Other signal processing functions can be controlled by the activation processor in a similar manner.

Abstract: A variable attenuator formed from a combination of PIN diodes is provided. The PIN diodes may be coupled in a “T,” “p” or other appropriate configuration. At radio frequencies (RF), a PIN diode acts as a variable resistor with a resistance value based on the bias current of the PIN diode. To control the attenuation level of the variable attenuator, the bias current of the PIN diodes are selectively adjusted. Digital values relating to selected bias currents, and thus selected attenuation levels, are stored in a memory. These digital values are provided as control signals that set the bias current levels for the PIN diodes. The bias current levels control the attenuation level of the variable attenuator.

Abstract: A portable table assembly supports a terminal on the main table portion thereof, and a keyboard on the auxiliary table portion thereof. The tilt of the main table, the vertical heights of the main and auxiliary tables, and the linear distance between the main and auxiliary tables are adjustable by a user sitting in a normal position adjacent the auxiliary table. Locking casters on the bottoms of the mobile base for the table assemblies may be locked or unlocked also from the user's sitting position, and the combined center of gravity of the main and auxiliary tables overlies a central leg of the base. A handle mounted to the rear of the main table also stops the terminal from sliding off the rear of the main table, and provides for proper positioning of the cords leading to the terminal.
