Patent number: 11998961Abstract: The invention relates to compositions and methods for reducing biocontaminant (for example flesh, blood, mucous, faeces or biofilm) on a surface, such as an endoscope surface. The compositions are viscoelastic and of low lubricity, having the following properties at 21° C.: a rotational yield point between 140% strain and 300% strain; a peak viscosity between 550 Pa·s and 2000 Pa·s; an oscillatory flow point between 250 and 700% strain; and a coefficient of friction ? which has a maximum value (preferably 0.06 or greater) in the viscoelastic liquid's elastohydrodynamic region.Type: GrantFiled: October 16, 2019Date of Patent: June 4, 2024Assignee: Saban Ventures Pty LimitedInventors: Alexander Galkin, Stefan Gebhardt, Ashwin Gopalan Nair, Brian Hingley, Joshua Storm Caley

Patent number: 7389404Abstract: A matrix data processor is implemented wherein data elements are stored in physical registers and mapped to logical registers. After being stored in the logical registers, the data elements are then treated as matrix elements. By using a series of variable matrix parameters to define the size and location of the various matrix source and destination elements, as well as the operation(s) to be performed on the matrices, the performance of digital signal processing operations can be significantly enhanced.Type: GrantFiled: September 12, 2005Date of Patent: June 17, 2008Assignee: G4 Matrix Technologies, LLCInventors: Gopalan Nair, Archana Sekhar, Prasanth David, Antony Jose

Patent number: 6195733Abstract: A multiprocessor data processing system includes a private data bus and a private program bus coupled to each of the processors. Coupled between the private data buses is a plurality of memory banks, each of which can be dynamically switched between the processors to move blocks of data without physically transferring the data from one bank to another. Likewise, a plurality of memory banks is coupled between the program buses. These memory banks are loaded with pages of program instructions from external memory over a shared bus. Any one of the pages can be coupled to either of the processors on its respective private program bus. When the pages are coupled to the shared bus, they appear as a contiguous address space. When a page is coupled to one of the private program buses, the addressing mode is changed so that the page is mapped to a common address space.Type: GrantFiled: October 21, 1998Date of Patent: February 27, 2001Assignee: Intel CorporationInventors: N. Gopalan Nair, David Regenold, Parviz Hatami, Ramprasad Satagopan

Patent number: 5862491Abstract: A method of using control channel information is provided to enhance data throughput of a cellular communication system. The cellular communication system includes a single system control unit coupled to a data pump, a cellular transceiver and a radio transceiver. A method of operating the cellular communication system includes the following steps: (a) detecting a control channel signal indicating that a channel interruption is to occur; (b) decoding the control channel signal; (c) sending the decoded control channel signal to the system control unit; (d) controlling the parameters of the adaptive components of the data pump so that the parameters remain at a converged state or are adjusted even during the channel interruption; (e) interrupting the channel; and (f) re-establishing the channel within a reduced retraining time period.Type: GrantFiled: October 13, 1997Date of Patent: January 19, 1999Assignee: Intel CorporationInventors: N. Gopalan Nair, Zdenek A. Brun
