Publication number: 20240112368Abstract: A method, system, and computer readable storage for identifying regions of interest on a casino gaming table. Regions of interest are locations on an image where relevant actions are typically going to occur. For example, locations of betting area region of interest and card area regions of interest are determined so that these areas can be analyzed on a video camera. The analyzed areas can then be used for things such as determining and tracking player betting amounts, determining if the game is being dealt properly (by analyzing the cards dealt to determine if the proper cards are dealt and/or the proper payouts are made).Type: ApplicationFiled: December 6, 2023Publication date: April 4, 2024Inventors: Ryan McClellan, Brett Tinling, Robin Groenevelt

Patent number: 11632147Abstract: A physical layer transceiver for a data channel includes receiver circuitry configured to receive signals on the data channel, transmit circuitry configured to transmit signals onto the data channel, and adaptive filter circuitry coupled to the receiver circuitry and the transmit circuitry and configured to filter the data channel by operating on input frequency-domain data samples to output filtered data samples. The adaptive filter circuitry includes error sample generation circuitry configured to generate error samples representing a difference between a target response and the filtered data samples, arithmetic-only circuitry configured to approximate a windowing function to operate on the error samples, and output sample generation circuitry configured to operate on windowed error samples to provide the output filtered data samples. The comparison circuitry may be configured for time-domain operation and may further be configured to transform the error signals into frequency-domain error signals.Type: GrantFiled: August 12, 2021Date of Patent: April 18, 2023Assignee: Marvell Asia Pte, Ltd.Inventors: KuoRuey Han, Brett McClellan, Leon Yang

Patent number: 9451057Abstract: In a method for coding a packet of information words into a frame for transmission, blocks of input data are received, the input data including control words and the packet of information words, the packet having (a) a start preceded by ones of the control words and (b) an ending followed by others of the control words, the blocks being smaller than the packet. When the block consists exclusively of information words, a one bit block header having a first sense is appended to the block to form the frame. When the block does not consist exclusively of information words: the block is condensed to accommodate a TYPE word, the TYPE word is inserted into the block, and a one bit block header having a second sense, opposite to the first sense, is appended to the block to form the frame.Type: GrantFiled: June 24, 2013Date of Patent: September 20, 2016Assignee: MARVELL INTERNATIONAL LTD.Inventor: Brett A.

Patent number: 8885664Abstract: A method for converting a data stream from a first rate to a second rate NA times greater than the first rate, such that the converted data stream conforms to a coding requirement that symbols be arranged in units of symbol length M, includes receiving, at the first rate, a data packet, and an inter-packet gap containing Y1 idle symbols, generating NA repetitions of each data symbol of the data packet, determining whether replicating each symbol of the inter-packet gap NA times would violate the coding requirement, and, at least partially in response to determining that replicating each symbol of the inter-packet gap NA times would violate the requirement, generating greater than or less than Y1*NA idle symbols. The method also includes outputting, at the second rate, the generated NA repetitions of each data symbol and the generated idle symbols.Type: GrantFiled: August 22, 2012Date of Patent: November 11, 2014Assignee: Marvell International Ltd.Inventors: William Lo, Brett A.

Patent number: 8873579Abstract: A method for inserting ordered sets into a data stream converted from a first rate to a second rate NA times greater than the first rate, while conforming to a requirement that symbols be arranged in units of symbol length M, includes receiving, at the first rate, a data packet containing data symbols, receiving Y1 symbols of control information, and identifying an ordered set based on the Y1 symbols. The method also includes generating NA repetitions of each data symbol of the data packet, determining whether Y1*NA/M has a non-zero remainder, and, at least partially in response to determining that Y1*NA/M has a non-zero remainder, generating a number of repetitions of the ordered set containing either more or fewer than Y1*NA symbols. The method also includes outputting, at the second rate, the data symbol repetitions and first ordered set repetitions.Type: GrantFiled: August 22, 2012Date of Patent: October 28, 2014Assignee: Marvell International Ltd.Inventors: William Lo, Brett A.

When the block does not consist exclusively of information words the one bit block header has a second sense, opposite to the first sense. Use of a one bit block header reduces overhead. Forward error correction is also utilized.Type: GrantFiled: September 28, 2010Date of Patent: June 25, 2013Assignee: Marvell International Ltd.Inventor: Brett A. McClellan

Patent number: 8461848Abstract: An apparatus and method for cable diagnostics is disclosed for deployment as part of an Ethernet communication system to conduct diagnostics. The system transmits one or more pulses which are Ethernet compatible and of finite duration. Reflections are detected and through processing and measurement of the amplitude and round-trip delay of the pulse's reflection, cable faults are located. In one embodiment, this innovation uses an IEEE 802.3 compliant transmit pulse, such as an auto-negotiation signal (AN pulse), to conduct cable diagnostics. The benefits of a standard compliant allow for use with any vendor on the far-end and the signal requires no special hardware or software to produce and, therefore, reduces system complexity and cost. To reduce incorrect measurements, the apparatus measures cable length and termination with multiple AN pulses. It then applies non-linear filters to redundant measurements in such a way that it produces accurate cable diagnostics information.Type: GrantFiled: December 9, 2009Date of Patent: June 11, 2013Assignee: Marvell International Ltd.Inventors: Divya Srinivasan Breed, Brett McClellan
