Title: Life-savingfloat
Inventor: LAHTINEN MIKKO PETTERI
IPC: B63C9/15
Filed: 1994-03-15
Abstract: The present invention relates to a life float. The life float comprises a stretching capsule and a string or cord starting at the ends thereof, arranged to pass around over a shoulder and under an arm. The watertight capsule consists of a part resembling a test tube and a cap in the shape of a test tube bottom. The inside of the capsule includes a float to be filled, a small gas capsule and a pricking mechanism therebetween for the gas capsule, a pressure reducer, an air valve, and a whistle. The capsule is to be placed close to the chest so that a person can reach it with hands. When needing the float, the person catches the capsule and pushes it further off from his/her body. Hereby, the cap of the watertight capsule opens, owing to the pulling movement caused by thread (1), and the threads pull the entire float out. The rest of the inside remains within the capsule. As the float is extracted, the mechanism pricks the gas container, thus making the float to be filled. The fill-in gas passes through the loud whistle. When the float is filled, the string on the shoulder can also be passed under the arm.

Title: Occupant restraint system actuated by a simple operation using a feature value
Inventor: IYODA MOTOMI
IPC: B60R21/16
Filed: 1995-10-23
Abstract: An occupant restraint system is disclosed in which a determination on the actuation of the system is made by a simple calculation.  A first feature value is extracted from a first component of acceleration caused by an external force exerted on a vehicle in a first direction, the first feature value representing a first vector of the external force with respect to the first direction.  A second feature value is extracted from a second component of the acceleration in a second direction, the second feature value representing a second vector of the external force with respect to the second direction.  A magnitude and a direction of a synthesized vector is obtained by synthesizing the first vector and the second vector.  A projective magnitude of a projective vector is obtained from the synthesized vector, the projective vector being a vector which is a projection of the synthesized vector with respect to a predetermined direction.  Actuation of the restraining means is determined by comparing the projective magnitude with a predetermined threshold value so that the restraining means is actuated when the projective magnitude is greater than the predetermined threshold value.

Abstract: This invention relates to a new and useful improvement in a wiper for use on thewindshields of vehicles, such as automobiles, trucks, trains, boats, airplanes and the like, and more particularly to improvements in a windshield wiper which is electrically heated so as to prevent the accumulation of ice, sleet or snow on the wiper blade. Moreparticularly, this invention has references to an improved heating arrangement designed to be used in windshield wiper assemblies with minimum modification or redesign of the blade-supporting, oscillating means, etc.  A spiral coiled heating element of resistance wire and a fluid dispensing arrangement for dispensing heated fluid are disposedsubstantially within the entire length of the passageway of the wiper blade. Tubes of electrical conductive material enter the passageway at the first and second passageway ends thus providing a means for both heat and/or fluid conveyance and an entrance and exits for the current and fluid. The ends are then sealed with a moisture proof sealant which also serves to maintain stability of end connections. The heating arrangement is connected to the vehicle battery to heat the heating element and fluid contained inside the blade passageway allowing the entire outer circumference of the wiper body and the wiping surfaces to melt ice surrounding the wiper and ice present on the windshield. Therefore the fluid is prevented from freeze-up and spray nozzle remains operable. The reciprocating spray nozzle is designed to spray ahead of wiper in both upward and downward movement. If desired the fluid dispensing arrangement can be used without heating the fluid.
