Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: In an embodiment, a device includes: an integrated circuit die; an encapsulant at least partially surrounding the integrated circuit die, the encapsulant including fillers having an average diameter; a through via extending through the encapsulant, the through via having a lower portion of a constant width and an upper portion of a continuously decreasing width, a thickness of the upper portion being greater than the average diameter of the fillers; and a redistribution structure including: a dielectric layer on the through via, the encapsulant, and the integrated circuit die; and a metallization pattern having a via portion extending through the dielectric layer and a line portion extending along the dielectric layer, the metallization pattern being electrically coupled to the through via and the integrated circuit die.

Abstract: A drip irrigation emitter has an outer element and a flow-restricting element. The outer element has a channel, an inlet and an outlet. The flow-restricting element is detachably mounted in the channel of the outer element. The flow-restricting element has a body, a passageway, a piercing portion and multiple notches. The passageway is helically formed around the body and has a caliber. The piercing portion is mounted on the body and protrudes out of the inlet. The notches are formed around the body between a first end surface of the body and the piercing portion and are in communication with the passageway. Each one of the notches has a caliber that is smaller than the caliber of the passageway to prevent the passageway from obstruction by the impurities. The piercing portion can directly pierce into a water supply tube for adjusting to plants accurately.

Abstract: An apparatus for adjusting a digital setting value at a variable speed includes an up key and a down key for generating a plurality of up and down pulses, an input/output interface connected to the up key and the down key, a processor connected to the input/output interface, and a display. The processor, in which a default digital setting value is stored, receives the up pulses and the down pulses through the input/output interface. The processor adds an adjustment value to or subtracts the adjustment value from the default digital setting value according to a time interval between adjacent two of the up pulses or adjacent two of the down pulses so as to obtain a digital output value to be outputted to the display, which displays the digital output value. The adjustment value increases as the time interval decreases.

Abstract: An interposing cushion and method of application for stabilizing a cylindrical container placed in a rectangular cavity of a cushion structure. The interposing cushion includes a rectangular shaped base member adapted to fit a rectangular cavity in a cushion structure made for stacking inside a shipping box. The cushion structure is produced to protect rectangular shaped containers containing fragile objects. The base member has a top surface and a bottom surface and four sides. Four corner support members longitudinally extend upwards from the top surface. The support members form circumscribed inner surface segments for supporting the cylindrical container. The bottom surface has four shock absorbing spacer legs formed inboard of each corner.

Abstract: A stepping motor driving apparatus with dynamic torque control includes a motor controller, a motor driver, and a frequency-to-voltage converter. In practice, the clock signals are sent to the motor driver and the frequency-to-voltage converter. When the motor is required to increase its speed, the system will increase the frequency of the clock signal CK. The reference voltage Vr will synchronously increase and generate higher driving current to drive the stepping motor so that the torque becomes larger. Besides, when the system fails and causes the stepping motor to run stiff, the system will reduce the driving current to the minimum automatically. It effectively avoids excessive heating and increases the security to the system.
