Abstract:
A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

Abstract:
An electronic device includes a printed circuit board (PCB) having at least one conductive trace thereon. A system on chip (SoC) is mounted on the PCB and electrically coupled to the conductive trace. A sensor chip is mounted on the PCB in a spaced apart relation with the SoC and electrically coupled to the conductive trace such that the sensor chip and SoC are electrically coupled. The sensor chip includes an accelerometer and/or a gyroscope, and a control circuit. The control circuit is configured to receive configuration data as input, acquire data from the accelerometer and/or the gyroscope. The control circuit is also configured to process the data so as to generate a context of the electronic device relative to its surroundings, the processing being performed in using a processing technique operating in accordance with the configuration data, and output the context.
Abstract:
A display control apparatus for a meter is provided. The display control apparatus includes a rotation sensor and an electronic control unit. The electronic control unit is configured to: (i) during a shift of the automatic transmission, calculate an estimated engine rotation speed estimated on the basis of a gear position after the shift; (ii) during the shift of the automatic transmission, control the meter such that the meter displays the estimated engine rotation speed; and (iii) when the engine has changed from a driving state to a driven state during the shift or the engine has changed from the driven state to the driving state during the shift, control the meter such that the rotation speed of the engine, displayed on the meter, is changed from the estimated engine rotation speed to the rotation speed of the engine, detected by the rotation sensor.
Abstract:
The present invention is intended to notify vehicle deceleration information more accurately. When an engine torque Te has a negative value, a sound volume adjustment coefficient kt is calculated depending on the engine torque Te, and a sound volume is adjusted depending on the sound volume adjustment coefficient kt. The sound volume adjustment coefficient kt is set to have a larger value as the absolute value of the engine torque Te becomes larger.
Abstract:
A detecting circuit for a number of fans includes a connector module and a controller. The connector module includes a number of connectors. Each connector outputs a first signal or a second signal depending on the connection or non-connection to a fan. The controller receives a speed signal of the fan upon receiving the first signal which indicates a connected state.
Abstract:
A sensor is provided for measuring the speed of a moving sport object, for example, from a gun, bow or other implement, such as a bullet or paint ball or arrow. The sensor is operable over a short range and is preferably mounted in close proximity to the path of the moving object preferably utilizes CW Doppler radar of a microwave radio frequency. In use, the unit is situated so as to place a transmit/receive antenna close to or in the line of motion of the object. Such an antenna, so positioned, may be separated from the unit and connected through a transmission line. The remote display/annunciator can also or in the alternative be separated and located remote from the transmitter/receiver and connected by a cable or a wireless link. The sensor is useful for other speed measurements in sports applications, such as for measurement of bat speed, golf club head speed or the speed of another racket, club or bat type implement, or to measure punch or kick speed in martial arts.
Abstract:
A method of determining the acceleration of a rotating body by counting the number of teeth on a rotating gear member for one or more revolutions. The method minimizes the measurement lag using an overlapping method and calculating acceleration on each control loop that a new revolution count is available. The method determines the new tooth count based on the tooth count estimated for the next update. The old tooth count is discarded and the new tooth count is adjusted to match the old tooth count within the system constraints to provide less interrupts and faster acceleration updates. The number of gear revolutions to be counted are increased at higher gear speeds.

Abstract:
There is disclosed a meter driving device which can perform a smooth indication through a simple process in response to an input pulse even if the frequency of the input pulse is relatively low.An edge detector generates a one-shot pulse each time the edge of an input pulse is detected by the edge detector. CPU performs a digital filtering process to the one-shot pulse in response to a start signal having a constant update cycle that is provided from a timer. Thus, the high-frequency components are removed from the one-shot pulse so that a DC component is taken out to provide an angular shift .theta. of an indicating arm corresponding to the frequency of the input pulse. This DC component is used to move the indicating arm through a indicator drive device.
