Publication number: 20240129681Abstract: In general, various aspects of the techniques are directed to rescaling audio element for extended reality scene playback. A device comprising a memory and processing circuitry may be configured to perform the techniques. The memory may store an audio bitstream representative of an audio element in an extended reality scene. The processing circuitry may obtain a playback dimension associated with a physical space in which playback of the audio bitstream is to occur, and obtain a source dimension associated with a source space for the extended reality scene. The processing circuitry may modify, based on the playback dimension and the source dimension, a location of the audio element to obtain a modified location for the audio element, and render, based on the modified location for the audio element, the audio element to one or more speaker feeds. The processing circuitry may output the one or more speaker feeds.Type: ApplicationFiled: October 12, 2022Publication date: April 18, 2024Inventors: Isaac Garcia Munoz, Alex Tung, Graham Bradley Davis, Andre Schevciw

Patent number: 9649848Abstract: Embodiments described herein provide ink recirculation capabilities for Drop-On-Demand (DOD) printing systems. One embodiment comprises a system that includes a controller, a DOD print head, an ink tank, an ink pump, and a recirculation cap. The ink pump transports ink from the ink tank to the DOD print head, and the recirculation cap captures ink ejected by the DOD print head. The recirculation cap also transports the capture ink to the ink tank. In response to detecting a start of an ink recirculation cycle, the controller collocates the recirculation cap proximate to nozzles of the DOD print head, and directs the DOD print head to begin ejecting ink through the nozzles into the recirculation cap for transport of the captured ink to the ink tank. The controller detects an end to the ink recirculation cycle, and directs the DOD print head to stop ejecting ink into the recirculation cap.Type: GrantFiled: February 24, 2016Date of Patent: May 16, 2017Assignee: Ricoh Company, Ltd.Inventors: Carlton E.

Patent number: 7890005Abstract: A method, system, and manufacture for adjusting electrostatic charges in a laser printer. A charge is applied to a photoconductor drum surface to create a dark voltage. An image area of the photoconductor drum is exposed with a printhead using a defined energy level to discharge the charge from the image area. An exposure voltage of the photoconductor drum is measured after the image area has been exposed. A first optimization is performed to determine an adjusted dark voltage and an adjusted energy level based on the measured exposure voltage and the dark voltage and the energy levels applied to the photoconductor drum. An applicator voltage is applied to an applicator that applies toner to the exposed image area of the photoconductor drum. Toner density applied to the photoconductor drum is measured and a second optimization is performed to adjust the applicator voltage to produce a target toner density.Type: GrantFiled: January 7, 2009Date of Patent: February 15, 2011Assignee: Infoprint Solutions Company, LLCInventors: Timothy Graham Bradley, Larry M.

Patent number: 7559627Abstract: An apparatus, system, and method are disclosed for electrorheological printing. The apparatus includes a pressurized ink chamber, a stimulator, and an electrode arrangement. The pressurized ink chamber is configured to retain an electrorheological ink and, under certain circumstances, discharge the electrorheological ink through one or more nozzles in a nozzle array. The stimulator is configured to generate a synchronization signal to increase the pressure of the electrorheological ink in the pressurized ink chamber. The electrode assembly is configured to create an electric field at each of the nozzles in the nozzle array. The electric field within the volume of a single nozzle acts as an electrorheological valve to change the viscosity and control the flow of the electrorheological ink within the nozzle. The absence of an electric field allows the electrorheological ink to fully discharge. A strong electric field stops the flow of the electrorheological ink.Type: GrantFiled: March 12, 2004Date of Patent: July 14, 2009Assignee: InfoPrint Solutions Company, LLCInventor: Timothy Graham Bradley
