Abstract: The present invention is a robotic hand device with thenar muscles, comprising a finger unit, a palm unit, a thenar unit, a first drive unit, a second drive unit, and a processor unit. When the processor unit issues a gripping instruction, the processor unit drives the finger units and the palm unit through the first drive unit to bend towards a central area of the palm until the finger units and the palm unit grip the object, and the processor unit drives the thenar unit through the second drive unit to move towards the central area of the palm until the thenar unit leans against the object. In this way, the robot hand device with thenar muscles using lead screw mechanism can firmly grip the object through the thenar unit in a more stable manner to improve a dynamic holding stability and to reduce risks of dropping the object.

Abstract: A charge-discharge device with active temperature control, connected with an external air blowing device, includes a battery compartment, a battery module, a controller and at least one temperature sensor. The battery compartment includes an accommodation space, at least one air inlet pipe and at least one air outlet pipe. The battery module is arranged in the accommodating space for charging or discharging. The controller determines whether the temperature of the accommodating space is within a working temperature range of the battery module according to the temperature sensor. When the temperature of the accommodating space exceeds the working temperature range, the controller controls the external air blowing device to supply cold or warm air. The cold or warm air flows into the accommodating space through the air inlet pipe and flows out through the air outlet pipe to achieve the effect of cooling or warming the battery module.

Abstract: The water hammer effect mitigation controlling device of solenoid valve for fluid of the present invention includes a controller and a solenoid valve. The controller generates and transmits a control signal to the solenoid valve when receiving a closing command. The control signal includes alternatively arranged multiple closing and open signal intervals. The time duration of the closing signal interval is shorter than the closing reaction time of the solenoid valve, the closing distance of the valve body during each closing signal interval is larger than an opening distance during each open signal interval, and the valve body is switched to a closed state during the control signal. The opened-closed switching time is prolonged by multiple closing and open signal intervals, and the water hammer effect caused by suddenly closing the valve body is reduced with no extra hardware, giving the present invention the advantage of lowered cost.

Abstract: A charging and discharging device with active temperature control includes an outer shell, an inner shell, a battery module, a controller and at least one temperature sensor. Wherein, the inner shell includes a thermoelectric material layer. The controller can determine whether the temperature inside the inner shell is within a working temperature range of the battery module according to the at least one temperature sensor. When the temperature inside the inner shell is not within the working temperature range of the battery module, the controller actively controls the battery module to output a supply voltage to the thermoelectric material layer. Then the temperature inside the inner shell can be controlled to rise or fall according to the principle of the thermoelectric effect, thereby changing and maintaining the battery module's temperature within the working temperature range to operate normally.

The signal processing module receives the first sensing signal or the second sensing signal, and controls the monitor module to display a measured value accordingly. With two different sensing signals, the current detecting module or the current tester can be used to measure different ranges of currents and achieve high accuracy at the same time.

Abstract: A power supply having a mixed regulator is able to provide the suitable power source according to the changing load by a switching mode voltage circuit and a series pass controlling circuit. The series pass controlling circuit has high sensitivity in detecting the changing the load, thus the power supply offers the suitable power source according to the changing of the load. The switching mode voltage circuit controls the transformer to output voltage by a PWM IC, so that the transistors for driving the transformer need not be powerful transistors which generate excessive heat. Thus a heat sink is not necessary and the power supply can accordingly be of a compact size.

Abstract: A technique for estimating a traction characteristic of a surface under a moving vehicle, such as the coefficient of friction of the surface. The traction characteristic can be estimated by generating a torque signal representative of at least an estimate of the amount of torque applied to the driven wheels of the vehicle. A load signal representative of at least an estimate of the load or weight applied to the driven wheels also is generated. The value of the torque signal is divided by the value of the load signal in order to generate a characteristic signal. Depending on the amount of slippage between the driven and non-driven wheels of the vehicle, the characteristic signal can be stored in order to provide an estimate of the traction characteristic of the surface in real time.

Abstract: A method is provided, for use in controlling an apparatus or for use by a controller of apparatus, for estimating a single torque variable utilizing multiple models. In one embodiment, the apparatus is a vehicle. The method includes the steps of sensing operating parameters to obtain associated operating signals and obtaining estimates of the torque variable from at least two independent models. Each model generates a torque estimate signal based on the operating signals. The method also includes the steps of weighting the individual torque estimate signals according to a predefined accuracy of the associated torque model, to obtain a plurality of weighted individual torque estimate signals, and generating a final torque estimate signal based on the weighted individual torque estimate signals. Once the final torque estimate signal is obtained, the apparatus can be controlled based on the final torque estimate signal.

Abstract: Techniques for controlling the spin of driven wheels of a vehicle also including non-driven wheels and an engine controlled by a spark angle and/or throttle position. The spark angle is controlled by a signal responsive to a slip error signal and a slip error derivative signal in order to alter the spark angle in a manner that controls the spin of the driven wheels. The throttle position is controlled by a throttle position control signal that is responsive to a slip error signal, a slip error derivative signal, and a slip error integration signal, in order to adjust the throttle position in a manner that controls the spin of the driven wheels. Wheel spin also can be controlled by the combination of a spark angle control signal and a throttle position control signal.

A drive signal having a value dependent on the value of the characteristic signal is then generated. The engine torque is varied in response to the drive signal in order to control the spin of the driven wheels of the vehicle.

Abstract: In a powertrain including an engine controlled by the position of the throttle valve, a hydrodynamic torque converter and multiple ratio automatic transmission connected to the drive wheels of the vehicle, a solenoid-operated hydraulic valve supplies pressurized fluid to engage and release the clutch that controls torque transfer between an offgoing clutch and an oncoming clutch. The position of the throttle valve and the speed of the engine are applied as input to a mathematical model programmed in algorithmic form for execution by a digital microprocessor. The engine produces a signal representing net torque output by the engine and torque converter, which signal is applied as input to an inverse mathematical model of the solenoid-operated valve that supplies hydraulic fluid to the controlling clutch. The unique relationship of phase to gain, the frequency response of the solenoid valve, is inverted within the frequency range of interest to remove the effects of delay.
