Abstract: A snowmobile having a liquid-cooled engine with an improved cooling system is disclosed. The snowmobile has a chassis with a drive tunnel. Horizontal footrests extend laterally from opposite sides of the chassis. The snowmobile also has left and right elongate side coolers that dissipate heat generated by the engine. The side coolers have a hollow interior that is in fluid communication with liquid coolant passages in the engine. Each cooler extends longitudinally and is mounted at an outer edge of a respective footrest to form a footwell. The snowmobile has a pump that circulates coolant throughout the coolant circuit formed by the side coolers and the internal passages of the engine. The side coolers may also contain heat exchanging anti-skid studs that extend outward from the surface of each side cooler. The snowmobile may also contain front and rear heat exchangers connected within the coolant circuit and positioned at the front and rear ends of the tunnel, respectively.

Abstract: An air/sea temperature probe is disclosed which can be deployed from a moving ship to detect the temperature profile of the atmosphere and ocean beyond the thermal influence of a ship. The probe includes a temperature transducer which utilizes a bifilar wire that provides a very quick air temperature time constant. The transducer is mounted within a radiation shield having low thermal conductance to minimize thermal and solar radiation contamination and is coupled to a signal processing network. In operation, the probe is deployed from a ship and provides temperature telemetry via an electrical data link coupled between the signal processing network and a receiving transducer located onboard the ship.

Abstract: The invention provides an automatic gain control system that is implemented by digital hardware. The digital hardware determines the range of a set of digital data values, and then examines each digital data value in a sequence. An index counter increments a sample count index i each time a new digital data value is examined and determines the absolute value of the ith digital data value. The digital hardware also counts both the number j of digital data values that exceed a high percentage value of the range, and the number k of digital data values that are less than a low percentage value of the range as the digital hardware runs through the sequence. If the digital hardware determines that a digital data value is greater than the high percentage value, the ratio j/i exceeds a first threshold value, and the gain level is not set to the lowest gain level, then the gain is decreased. If the digital hardware determines that a digital data value is less than the low percentage value, the ratio k/i exceeds a second threshold value, a predetermined interval of time has elapsed, and the gain level is not set to the highest gain level, then the gain is increased.

Abstract translation: 本发明提供一种由数字硬件实现的自动增益控制系统。 数字硬件确定一组数字数据值的范围，然后按顺序检查每个数字数据值。 每当检查新的数字数据值时，索引计数器递增样本计数索引i，并确定第i个数字数据值的绝对值。 数字硬件还计数超过范围的高百分比值的数字数据值的数量j，以及当数字硬件通过序列运行时小于范围的低百分比值的数字数据值的数量k 。 如果数字硬件确定数字数据值大于高百分比值，则比率j / i超过第一阈值，并且增益电平未被设置为最低增益电平，则增益减小。 如果数字硬件确定数字数据值小于低百分比值，则比率k / i超过第二阈值，经过预定的时间间隔，并且增益水平未被设置为最高增益水平， 那么增益就会增加。

Abstract: A system for minimizing the power requirement of a flowmeter intended for long-term unattended deployment in a current flowing through a body of conductive fluid. The system includes a pair of electrodes in contact with the fluid, and a permanent magnet which generates a magnetic field which is orthogonal to a line passing between the electrodes. An electromagnetic coil is also provided, and is selectively activated and deactivated to establish the orthogonal magnetic field at a first level during first time periods in a series of first time periods, and at a second level during second time periods in a series of second time periods. The ratio of the time duration of a first time period to a second time period is substantially less than one. Means coupled to the electrodes generate a first signal during a first time period and a second time signal during a second time period, the first and second signals together enabling determination of an error term, comprising the potential difference between the electrodes when the electrodes are in contact with the fluid, and there is no magnetic field proximate to the electrodes.
