Title: Method of linearizing a flow velocity sensor and a linearized flow velocity measurement apparatus
Inventor: RYHANEN TAPANI
IPC: G01P5/16
Filed: 1995-12-19
Abstract: The invention relates to a method and apparatus for linearizing a flow velocity sensor based on pressure difference measurement. According to the method, such a difference of two pressure signals (4, 5) is measured from the flow under measurement that is proportional to the square of the flow velocity, the difference of said two pressure signals (4, 5) is measured using a micromechanically manufactured symmetrical capacitive differential pressure sensor (20) based on the force balance principle, in which sensor the pressure-induced deviation from force balance is compensated for by inducing on the pressure--sensing diaphragm (23) of said differential pressure sensor (20) a force-balance-restoring electrostatic pressure so that the pressure--sensing diaphragm (23) is subjected to the force-balance-restoring electrostatic force, whereby the amplitude of the force-balance--restoring electrical feedback control signal, which also acts as the system output signal, is directly proportional to the square root of said difference of said two pressure signals, and thus, a linear function of the flow velocity. According to the invention, said feedback control voltage depending on the direction of the pressure difference is applied only to either of the stationary electrodes (21 or 22) disposed on the same side relative to the sensing diaphragm so that the electrostatic force of attraction thus induced acts counter to the force generated by the pressure difference under measurement, whereby the polarity of the system output voltage signal is dependent on the direction of the flow.

Filed: 1996-02-21
Abstract: There are various devices to help handicapped persons to get into and out of a bathhub. Such are chairs, powered up and down, usually by water pressure, to lower a person into the bathtub and then lift him high enough to make standing up easier.   The ones on the market are unwieldy, relatively heavy struchlres with a chair mounted on them. The problems with them are the following:     1. Relatively heavy and unwieldy. Impossible to lift it by an average person in and out of the hub which is needed for cleaning or when a not handicapped would want to use the bathhub.   2. Being intricate structures it is very difficult to keep them clean from the dirty soapy deposits.   3. Being rather bulky and heavy it is also difficult to store when not in use.   4. The seat being relatively high a great percentage of the useful water depth is lost.   5. Its configuration is restricting to his-her movement.

Patent CA-2180497-A1 (CA)
Inventor: MOORMAN JAMES W
IPC: F02B75/02
Filed: 1996-07-04
Abstract: A single cylinder, internal combustion engine with a dry sump lubrication system.  The engine includes an engine housing in which the overhead camshaft (40) and crankshaft (42) are rotatably supported, and the housing includes an integrally formed cylinder (22) and head (24).  A timing belt (105) disposed externally of the engine housing interconnects the crankshaft and camshaft, and a piston (46) connected to the crankshaft reciprocates within an internal bore provided in the engine housing cylinder.  The cylinder wall (48) around the internal bore is of a generally uniform thickness and circumscribed by cooling fins such that the cylinder resists bore distortion during operation.  Dry sump lubrication is obtained by an external oil reservoir (135) connected to a pump (161) which supplies pressurized oil to the bearing journals of the camshaft.  The reciprocating motion of the valve assemblies (67, 68) controlling intake and exhaust of the combustion chamber pumps the oil which lubricated the camshaft back to the external reservoir. The reciprocating motion of the piston similarly effects a high pressure within the crankcase cavity to pump oil which has lubricated the crankshaft back to the external reservoir.
