88	System and method for estimating turbocharger operating speed	US14537100	2014-11-10	US09453468B2	2016-09-27	John N. Chi; John M. Mulloy; Sriram S. Popuri
A system and method are provided for estimating the operating speed of a turbocharger. A first pressure value corresponds to pressure at or near the air inlet of the compressor, and a second pressure value corresponds to pressure at or near the air outlet of the compressor. A temperature value corresponds to a temperature at or near the air inlet of the compressor, and a flow rate value corresponds to a flow rate of air entering the air inlet of the compressor. The operating speed of the turbocharger is estimated as a function of the first pressure value, the second pressure value, the temperature value and the flow rate value.
89	SYSTEM AND METHOD FOR WATER COLUMN AIDED NAVIGATION	US14439213	2013-10-28	US20150300822A1	2015-10-22	Brandon S. Strong
Underwater vehicles may fix their position from GPS at the surface of the water and use bottom track for dead reckoning once it has descended to within tracking range of the bottom of a body of water. This disclosure describes a method and system for navigation through the water through depths where GPS is not available using current profiles from sonar systems including acoustic Doppler current profilers (ADCP). This extrapolation of earth referenced current profiles can provide a way to estimate vehicle motion below the surface before the vehicle reaches the bottom. Once bottom track is achieved, the corrected reference for vehicle motion improves the vehicle position estimate. A Kalman filter updates vehicle position and current profile estimates during descent, and the bottom track when the bottom comes within range to enable navigation of underwater vehicles.

A circuit substrate 8 mounting a flow sensor 6 thereto is stored into a concave portion 7 formed on the lower face of a mouse case 2. When a mouse 1 is moved, a flow of the air is relatively caused by inertia of the air, etc. The movement of the mouse 1 is detected by detecting the flow velocity of this air by the flow sensor 6.
94	System for measuring the cyclic speed and rotational position of a traveling looped belt	US416297	1989-10-02	US4969360A	1990-11-13	Ryan P. Dougall
A system for determining the rotational, or cyclic, speed and rotational position of a looped traveling belt, such as a felt in a papermaking machine, utilizes a discontinuity, or caliper variation, in the surface of the belt near one edge thereof. A fluid stream, such as compressed air, is projected against the web along the annnular area containing the discontinuity, and a pressure transducer is mounted to fixed proximity with the belt downstream of, and aligned with, the fluid stream. The transducer senses differences in the pressure of the fluid stream projected against the belt and against the discontinuity, and produces a signal indicative of the passage of the discontinuity past the transducer. The time interval of this signal is used to compute the cyclic speed of the traveling belt and to identify the part of the belt passing through a nipped roll couple at another location.

96	Unitary fluidic angular rate sensor	US661904	1976-02-25	US4020700A	1977-05-03	Mario T. Lopiccolo; Max A. Schaffer; George A. Jachyra
The nozzle of an angular rate sensor which directs a stream of fluid toward a pair of temperature-dependent sensing resistor elements is formed in a major block which defines the chamber within which the sensing elements are also mounted, thereby to mitigate problems of aligning the jet with respect to the chamber and of aligning the sensing elements with respect to the nozzle. Within the casing, only the nozzle block, a diaphragm pump assembly, and an anvil need be mounted; these are secured by a lock nut, the pressure thereof being applied through a conical Belleville spring. A fine weld is used to hermetically seal the element, but the weld can be cut off without damage to the unit; so that by loosening the lock nut, the entire apparatus can be disassembled without destruction. Reference resistors, for a bridge to measure changes in the sensing elements, are mounted directly within the unit, to avoid bridge misbalances due to external connections.
97	Null adjustable vortex rate sensor	US358421	1973-05-09	US3960022A	1976-06-01	Arthur J. Ostdiek; Lyndon S. Cox
A null adjustable vortex rate sensor which enables the precise control andelocation of the stagnation point of the fluid stream with respect to the null line of the pickoff located within said chamber. The null adjustable vortex rate sensor is a vortex rate sensor with a fixed position pickoff and a fixed position drain, a rod being concentrically located in the drain and extended from the drain into the chamber. The horizontal adjustability of this rod inside the drain controls the location of the stagnation point at the pickoff within the chamber very precisely thus enabling one to approximately choose the location of the pickoff member and by means of the rod mechanism located in the drain move and adjust the stagnation point to obtain a null output at the fixed position of the pickoff. The pickoff provides a differential pressure signal which is a function of the angular rate of rotation of the chamber in inertial space.
98	Fluid angular rate sensor	US86339169	1969-07-17	USRE28622E	1975-11-25
An improved fluid readout means for devices that measure the angular rate of rotation of a body about an axis. A slotted cylinder is positioned in the drain of a vortex rate sensor, with its axis transverse to the drain axis. The slots are located in the upstream portion of the cylinder and are at a very small radius from the drain axis. As the helical angle of the flow through the drain changes due to change in rotation of the rate sensor the static pressure at the slots changes, and the pickoff produces a fluid output signal which is proportional to the angular rate of rotation of the sensor. Increased sensitivity may be achieved by introducing an airfoil section upstream of and in close proximity with the slotted cylinder. Alternatively, an airfoil section can be positioned to extend completely across the drain and serve to direct the helical flow to a splitter located downstream of the airfoil to produce a high flow output signal that is proportional to the angular rate of rotation of the sensor.
