Patent number: 11352937Abstract: A marine drive is for propelling a vessel in body of water. The marine drive has a powerhead, a crankcase on the powerhead, and a cooling system that pumps a first flow of cooling water from the body of water through a powerhead cooling conduit for cooling the powerhead and in parallel pumps a second flow of cooling water from the body of water through a crankcase cooler for cooling the crankcase and lubricant in the crankcase. A valve controls the second flow of the cooling water to the crankcase cooler. The valve is normally positioned in a closed position, which inhibits the second flow of cooling water to the crankcase cooler and thereby reduces condensation of water from the lubricant in the crankcase. The valve is moved into an open position upon operation of the powerhead at or above a threshold speed, which permits the second flow of cooling water to the crankcase cooler and thereby cools the lubricant in the crankcase.Type: GrantFiled: February 8, 2021Date of Patent: June 7, 2022Assignee: Brunswick CorporationInventors: Robert Dreyer, Chetan Avinash Dharmadhikari, Nathan C. King, Barry P. Schleicher

Patent number: 10936943Abstract: Providing flexible matrix processors for performing neural network convolution in matrix-processor-based devices is disclosed. In this regard, a matrix-processor-based device provides a central processing unit (CPU) and a matrix processor. The matrix processor reorganizes a plurality of weight matrices and a plurality of input matrices into swizzled weight matrices and swizzled input matrices, respectively, that have regular dimensions natively supported by the matrix processor. The matrix-processor-based device then performs a convolution operation using the matrix processor to perform matrix multiplication/accumulation operations for the regular dimensions of the weight matrices and the input matrices, and further uses the CPU to execute instructions for handling the irregular dimensions of the weight matrices and the input matrices (e.g., by executing a series of nested loops, as a non-limiting example).Type: GrantFiled: August 30, 2018Date of Patent: March 2, 2021Assignee: Qualcomm IncorporatedInventors: Colin Beaton Verrilli, Mattheus Cornelis Antonius Adrianus Heddes, Natarajan Vaidhyanathan, Koustav Bhattacharya, Robert Dreyer

Patent number: 10747501Abstract: Providing efficient floating-point operations using matrix processors in processor-based systems is disclosed. In this regard, a matrix-processor-based device provides a matrix processor comprising a positive partial sum accumulator and a negative partial sum accumulator. As the matrix processor processes pairs of floating-point operands, the matrix processor calculates an intermediate product based on a first floating-point operand and a second floating-point operand and determines a sign of the intermediate product. Based on the sign, the matrix processor normalizes the intermediate product with a partial sum fraction of the positive partial sum accumulator or the negative partial sum accumulator, then adds the intermediate product to the positive sum accumulator or the negative sum accumulator.Type: GrantFiled: August 30, 2018Date of Patent: August 18, 2020Assignee: Qualcomm IncorporatedInventors: Mattheus Cornelis Antonius Adrianus Heddes, Natarajan Vaidhyanathan, Robert Dreyer, Colin Beaton Verrilli, Koustav Bhattacharya

Patent number: 10725740Abstract: Providing efficient multiplication of sparse matrices in matrix-processor-based devices is disclosed herein. In one aspect, a matrix processor of a matrix-processor-based device includes a plurality of sequencers coupled to a plurality of multiply/accumulate (MAC) units for performing multiplication and accumulation operations. Each sequencer determines whether a product of an element of a first input matrix to be multiplied with an element of a second input matrix has a value of zero (e.g., by determining whether the element of the first input matrix has a value of zero, or by determining whether either the element of the first input matrix or that of the second input matrix has a value of zero). If the product of the elements of the first input matrix and the second input matrix does not have a value of zero, the sequencer provides the elements to a MAC unit to perform a multiplication and accumulation operation.Type: GrantFiled: August 30, 2018Date of Patent: July 28, 2020Assignee: Qualcomm IncorporatedInventors: Mattheus Cornelis Antonius Adrianus Heddes, Robert Dreyer, Colin Beaton Verrilli, Natarajan Vaidhyanathan, Koustav Bhattacharya

Patent number: 8899029Abstract: Apparatuses for marine propulsion systems having an internal combustion engine comprise an exhaust conduit conveying exhaust from the internal combustion engine; a cooling jacket on the exhaust conduit; and a cooling passage between the exhaust conduit and the cooling jacket. The cooling passage guides flow of cooling liquid from upstream to downstream towards a location where the cooling liquid is mixed with exhaust in the exhaust conduit. First and second baffles are axially spaced apart and extend transversely with respect to the cooling passage so as to disperse the flow of cooling liquid at the location where the cooling liquid is mixed with the exhaust, thereby reducing reversion of cooling liquid in the exhaust conduit. At least one catalyst and at least one oxygen sensor are disposed in the exhaust conduit. The oxygen sensor is adjacent to and oriented parallel to a downstream face of the catalyst so that exhaust flows perpendicularly across the sensor.Type: GrantFiled: December 3, 2012Date of Patent: December 2, 2014Assignee: Brunswick CorporationInventors: Robert Dreyer, Mark J.
