As an embodiment of the present invention, in a navigation system using an acceleration sensor, when position information cannot be obtained from a GPS processing section, a velocity detecting unit performs an operation using detected acceleration α G, a measurement time mt, a velocity V0 at a time t0, gravity acceleration g and an amount of height change Dh, according to Expression (11). By using the relationship among a gravity acceleration component gf, the gravity acceleration g, the amount of height change Dh and distance Dm shown in Expression (4), the gravity acceleration component gf can be offset by the amount of height change Dh. Therefore, velocity V can be calculated with high accuracy without receiving the effect of the gravity acceleration component gf.

| 223 | Apparatus for monitoring human body's movements in sport or medical domain, and its use | EP06425050.9 | 2006-02-01 | EP1688746A2 | 2006-08-09 | Facchielli, Duccio; Torti, Stefano; Verza, Andrea; Chiarugi, Antonio; Clot, Paolo Rosa; Clot, Marco Rosa |
A precise measurement of human body's movements is highly important in all those domain where monitoring such movements is essential to: screening the effort made during a movement, analyzing human limits in performing such movements, train and improve human abilities of movement performance. Such context are easily found in the rehabilitation domain and/or physical training. This immediately leads to physiotherapy and sport. However, current methods (especially in sports) are extremely expensive because they involve the use of cameras and ultrasound acquisition systems. A widely used system uses accelerometers to assess acceleration, and mathematically deduct velocity, strength, and power of a movement. But, a serious limitation of all the already patented inventions using accelerometers and of their mechanism is that in no case they obtain a precise estimation of the monitored object (or a part of it) motion. The current industrial invention is, indeed, a new invention relating to a new system for estimating any body part displacement -and, therefore, motion―without any external reference, by means of inertial measurement. Furthermore, the proposed new method, unlike the potential competing technologies allows a very precise estimation of monitored motions.

| A shock pulse sensor (10) comprising a housing (46) and a sensor element. The sensor element, especially a permanent magnet (42), can be displaced along a predetermined path (x) in the housing at speed under the influence of an at least approximately pulse-type shock to the housing (46). The sensor element is mounted on the housing (46) with a guide element affecting the speed thereof. The sensor element consists of a magnetic material. A receiving element which is fixed to the housing is provided for magnetic generation of a measuring signal (UM) as a result of the movement of the sensor element caused by the shock. The movement of the sensor element generates a measuring voltage (UM) which is dependent upon the path (x) in said receiving element. The guide element alters the speed of the sensor element in such a way that the measuring voltage (UM) along the path (x) is dependent upon the duration of the pulse-type shock when the pulse surface is the same. | ||||||

A velocity information acquisition section 21 acquires velocity information on the velocity of a vehicle and records this acquired information in a velocity information recording section 27. A state judgment section 23 judges start and stop states of the vehicle based on state information indicating the start and stop states of the vehicle that was acquired at a state information acquisition section 22. After this judgment, a minimum output velocity computing section 24 accurately computes, based on the velocity information recorded in velocity information recording section 27, a minimum output velocity in a period in which a vehicle velocity detection circuit 10 cannot detect velocity information. A movement condition computing section 25 can appropriately compute a relative movement distance or a relative movement velocity of the vehicle based on the state information acquired at state information acquisition section 22 and the minimum output velocity computed at minimum output velocity computing section 24. |

| The invention relates to a method for determining the speed of a wheel on a motor vehicle. To achieve this, an acceleration sensor is mounted on the wheel. According to the invention, the frequency φ or the cycle T of an alternating signal caused by the influence of the ground acceleration g is determined as the speed of the wheel. Said alternating signal is contained in the acceleration signal provided by the acceleration sensor. The method can be used in automatic tyre-pressure monitoring systems to assign signals transmitted by a wheel electronic system by radio to a specific wheel position on the motor vehicle and to control the transmission rate of a wheel electronic system according to the speed. | ||||||

| The invention relates to a method for determining that a motor vehicle is climbing or descending a slope. According to said method, the vehicle acceleration aref is determined from Vref by differentiation and compared to the longitudinal vehicle acceleration aL determined by a sensor. The method checks whether there is a deviation from normal driving by monitoring whether aL - aref is greater than a threshold value SL. A deviation time t during which a deviation from normal driving is continuously present, is determined and is monitored for exceeding a minimum time value TM. The motor vehicle is deemed to be climbing or descending a slope when t is greater than TM. The invention also relates to a device which uses a digital logic with a counter to measure the time t, t1, t2 and tk. One digit of said logic corresponds to a fixed predetermined time unit. | ||||||

An apparatus (10) and a method provide a signal (12) indicative of velocity of a mass (18). An acceleration sensor (64) senses acceleration of the mass (18) and provides an acceleration signal (66) indicative of the acceleration of the mass. A displacement sensor (70) senses displacement of the mass (18) and provides for a displacement signal (72) indicative of displacement of the mass. Two filters (68 and 74) operate upon the acceleration and displacement signals (66 and 72) respectively, and the filter outputs are summed to provide the velocity signal (12). In one example, an active suspension system (16) utilizes the velocity signal (12) to control relative movement between the mass (18), as a sprung mass, and an unsprung mass (20). The suspension system (16) includes a controller (54), which receives the velocity signal (12) and provides a control signal (56) utilizing the velocity signal. A force actuator (30), between the sprung and unsprung masses (18 and 20), is controlled in response to the control signal (56). |

| A movement measuring device determines the speed of the body's specific movement on the basis of the maximum value of the acceleration sensed by an acceleration sensing unit attached to the body, when the body has made a specific movement. For example, when th e player wears the device on his arm and makes a punching motion, the punching speed is found from the maximum acceleration resulting from the punching action. Furhtermore, a game device obtains data indicating the magnitude of a specific movement of the body, on the basis of the acceleration sensed by an acceleration sensing unit, and then decides the outcome of the game is decided on the basis of the strength and weakness of the punch. This enables the user to easily play a fighting sport game involving the player's actual punching motions anywhere. | ||||||
