An example system includes an inlet, a guide structure, a heat exchange device and an outlet. In that example the heat exchange device is in thermal contact with the guide structure to change the temperature of print material. The print material may act on the temperature of a print head die while guided through the print head die.

Acting on the temperature of a print head die

Disclosed herein is a print head maintenance assembly, a printing device and a method of controlling a print head maintenance assembly in a printing device. The print head maintenance assembly comprises a maintenance cartridge comprising a positioning flag, wherein the maintenance cartridge is movable along a maintenance path in a direction of movement; and a sensor to detect the positioning flag to determine the position of the maintenance cartridge along the maintenance path.

Print head maintenance assembly

A cartridge for a printing system comprises a receptacle to receive waste printing material from the printing system, a floater to change its position based on a varying filling level of the waste printing material in the receptacle, and a flag mechanically coupled to the floater, wherein a position of the flag depends on the position of the floater and indicates, outside of the receptacle, the filling level.

In one example in accordance with the present disclosure, an interconnect on a print liquid supply is described. The interconnect includes a liquid interface to establish a liquid path between the print liquid supply and an ejection device in which the print liquid supply is installed. The interconnect also includes an electrical interface to establish a data transmission path between the print liquid supply and the ejection device. The interconnect also includes an external surface having a dampening element disposed thereon.

A method for adjusting latency in a video conference signal originating from a video conference camera and encoder is described herein. Latency in a video conference connection between more than two video conference sites is measured. The latency between each of the more than two video conference sites is compared with a latency threshold. Parameters of the video conference camera and encoder associated with each video conference site are adjusted by a video controller to modify the image quality of the video signal if the measured latency of a respective video conference connection is below the threshold.

Method for signal adjustment through latency control

A system and method of determining the identity of a caller in a local room from a remote room includes a local image capture device for capturing a plurality of images of a caller in the local room in real time. A remote codec receives the plurality of images of the caller. A remote viewscreen displays the plurality of images of the caller in real time in the remote room. A remote display monitor displays the plurality of images in real time after two-way communication is established between the local room and the remote room. The method includes establishing one-way communication between the local room and the remote room, transmitting the plurality of images of the caller to the remote room, displaying the plurality of images of the caller in real time on the remote viewscreen, and establishing two-way communication between the local room and the remote room.

A video camera calibration system includes a video camera, having a fixed location and a variable viewing orientation with respect to a fixed object, and a video calibration target, integral with the fixed object and having a known position. The viewing orientation of the video camera can be adjusted by aligning the position of the video calibration target in a video image produced by the video camera.

Video camera calibration system and method

A system including a first node configured to receive first data in a first format that specifies a network destination for the first data and convert the first data to second data in a second format that does not specify a network destination for the second data and a second node configured to receive the second data from the first node over a first connection and convert the second data to third data in a third format that specifies a network destination for the third data is provided.

Converting data from a first network format to non-network format and from the non-network format to a second network format

An apparatus has a content node to logically select a first A/V stream from an application layer of a first network and a collaboration node to logically select a second A/V stream from an application layer of a second network. A set of non-network media link interfaces are configured to transmit the second A/V stream from the collaboration node to the content node, and to transmit the first A/V stream from content node to the collaboration node. The non-network media link interfaces provide for limited information encoding to prevent network protocol information from being transferred between the first and second networks.

Synthetic bridging for networks

A technique for maintaining consistent video quality between a plurality of videoconference sites is disclosed. Calibration correction factors are determined from video calibration data obtained from the videoconference sites. The calibration factors are applied to transmissions between the videoconference sites.

Consistent quality for multipoint videoconferencing systems

A technique for enhancing the illusion of physical presence in a common space during a multipoint video conference is disclosed. The technique may include controlling the appearance of a first portion of the video images separately from an appearance of a second portion of the video images to achieve a consistent image appearance across the multipoint videoconference.

Videoconferencing with enhanced illusion of physical presence in a common space

Infrared light is emitted towards a surface. The infrared light is redirected by an object positioned on the surface. The infrared light as redirected by the objected is detected. A position of the object on the surface is determined based on the infrared light detected.

Detecting light to determine position of object

A fuel supply includes a fuel container having an interior chamber for containing fuel, and a pressure sensing unit disposed within the interior chamber of the fuel container. The pressure sensing unit is configured to provide an output signal indicative of an amount of fuel remaining in the fuel container.

Apparatus and method for integrating a fuel supply and a fuel level sensing pressure sensor

A method of creating a synthetic bridge () has select data () logically extracted from an application layer of a first network (A) which contains one or more first data streams to be transported to a second network (B). Select data () is logically extracted from an application layer of the second network (B). Select data () is logically extracted from an application layer of the second network (B) which contains one or more second data streams to be transported to the first network (A). The two or more first and second data streams are transported over separate sets of non-network media link interfaces (-) that only allow for limited information encoding and inherently prevent any network protocol information from being passed with the two or more first and second data streams until after the two or more first and second data streams are in the control of the opposite network from which they were transported.
