The water containers, water drip controlling device, water flow rate controlling device, AAB device and AWPAE devices constitute the irrigation device for field plants or potted plants culture. The combination of the wireless technologies with various sensors in one of three indicators enables the underground irrigation to be visible, hearable, viewable and remotely controllable at real time and real-location manner for precision management of plant cultivation. The movable device provides a way to monitor the water supply system and to calibrate data obtained from UIFR devices. All devices in the system are repairable and replaceable.

A lamp holder for an LED lamp string includes a base and an LED luminaire. The LED luminaire is inserted into the base. The base includes a casing, a cover, and a tail plug which are axially symmetric structures. The combination of the casing, cover and tail plug form a pin insertion hole of the LED luminaire and a wire inserting hole of a connecting wire of the lamp string, and the three are combined as a whole by a latch member, a latch slot, and a latch member. The cover and the tail plug seal an electrically conductive portion of the LED luminaire to provide a waterproof and dustproof effect. Since the casing, cover and tail plug are bilaterally symmetric structures, the level of difficulty of the alignment is reduced significantly. Automated equipment may be used for assembling the base in mass production, and the labor is reduced significantly.

A decorative lantern includes a plurality of constituent pieces made of a light-transmissible, heat-resisting, and flexible plastic material. Each of the constituent pieces has a radially inner zone at a first side thereof, and a radially outer zone at a second side thereof, and is formed at a radially inner edge with at least one recess portion. The constituent pieces are sequentially connected together by bonding the radially inner zone at the first side of a first constituent piece to a second constituent piece adjacent to the first side of the first constituent piece, and bonding the radially outer zone at the second side of the first constituent piece to a third constituent piece adjacent to the second side of the first constituent piece; and the recess portions of all the constituent pieces together define a receiving space in the decorative lantern for accommodating an electrically conductive light source therein.

Bit lines coupled to a column of SRAM core cells in an array are sensed asynchronously using zero DC power with either differential sense amplifiers or single-ended amplifiers, according to the present invention. The differential sense amplifier embodiment includes a pair of cross-coupled series-connected PMOS and NMOS transistors connected between the power supplies. Each bit line is coupled to an NMOS gate in the transistor pair, and each PMOS gate is coupled to the drain-source connection of the other series-connected PMOS-NMOS pair. The PMOS gates and PMOS-NMOS drain-source connections define the sense amplifier complementary output signals, whose states are determined by the bit line states. The single-ended embodiment is implemented as a PMOS-NMOS transistor pair inverter connected between the power supplies. Each inverter input is coupled to a bit line, and the inverter outputs are the sense amplifier outputs. In both embodiments, series-connected PMOS-NMOS pairs do not provide any DC path and function asynchronously without clock or enabling signals other than the bit line signals. In either embodiment, a zero DC power consumption bit-line clamp implemented as a PMOS-NMOS inverter is also coupled to each bit line, and is controlled by the associated sense amplifier output signal. The bit-line clamp forces an associated bit line to a full "1" or "0" logic state.

A retargetable SRAM system includes several block storage units that include a plurality of addressably selectable SRAM core cells, with a block single ended bit line driver coupleable to the output of each block storage unit to enhance voltage slew rate. To promote retargetability, digital (rather than analog) sense amplifiers are provided per each data output port. To minimize power-up crowbar current, the input of each unselected block bit line driver is forced to a "1" or "0" state. AMOS transistor coupled between the input port of each block bit line driver and an upper or lower system power supply has its gate input lead coupled to receive the system block select signal (or its complement). A desired SRAM core cell is accessed by specifying its row, column, and block address. A row select signal causes the cell output to be coupled to the input of the associated block bit line driver. The block select signal, its complement, and column select signal cause the output of the associated block bit line driver to be coupled to the input of the digital sense amplifier for the specified data output. The same block select signal (or its complement) turns on the MOS transistor coupled to the input node of each unselected block bit line driver. In a system with SRAM core cells arrayed into 128 rows and 256 columns, partitioned into four block storage units of 32 rows each, crowbar current is thus minimized for the 3.times.256 or 768 unselected block bit line drivers.

A display panel having a display region and a non-display region is provided. The display panel includes a plurality of pixel structures in the display region, and each pixel structure includes a scan line, a data line, a first active device, a pixel electrode, a first insulating layer, a capacitor electrode, and a second insulating layer. The first active device includes a first gate, a first channel, a first source, and a first drain. The second insulating layer covers the first insulating layer and the capacitor electrode and is located between the capacitor electrode and the first drain. At least one driving circuit is disposed in the non-display region and includes at least one second active device. Hence, a relatively thin insulating layer can be disposed between the capacitor electrode and the drain to reduce the area of the capacitor region and to achieve a desired aperture ratio.
