Abstract: Displays and display driving methods implement a pixel set/reset scheme. Pixel cells of an example display each include a set terminal, a reset terminal, an output terminal, and a set/reset circuit. Responsive to receiving a set signal on the set terminal, the set/reset circuit asserts a first signal on the output terminal and maintains the first signal on the output terminal until a reset signal is received on the reset terminal. Responsive to receiving a reset signal on the reset terminal, the set/reset circuit asserts a second signal on the output terminal and maintains the second signal on the output terminal until a set signal is received on the set terminal. The optical output of the pixel depends on when the first signal and the second signal are asserted on the output terminal of the set/reset circuit during a predefined modulation period.

Abstract: A static random access memory (SRAM) includes an input read register (IRR) for monitoring the state of external binary devices and an output drive register (ODR) for controlling the state of external binary devices. The SRAM can be a multi-port device for access by multiple processors or controllers. Each bit of the IRR can mirror the state of a connected external binary device. Each bit of the ODR can manipulate the state of a connected external binary device or can be read without changing the state. The memory device may include settable controlling bits and a set of controlled register bits. Setting the one or more controlling bits may define which controlled register bits are associated with the IRR and which are associated with the ODR.

The SRAM can be a multi-port device for access by multiple processors or controllers. Each bit of the IRR can mirror the state of a connected external binary device, and can be read to a connected processor using a standard read instruction. Each bit of the ODR can manipulate the state of a connected external binary device by providing the device with a path to the SRAM supply voltage. Each bit of the ODR can also be read without changing the state, or interrupting the operation of, the connected external binary device. When set to the proper mode, the addresses used for the IRR and ODR can be used with the SRAM main memory array for standard memory operations.

Abstract: A novel method and circuit are disclosed for providing an alternate function to a semiconductor device having a normal operating voltage range and an input pin for receiving an input signal of a voltage level within a normal signal voltage range, for selecting an alternate function, whose steps consist of determining, when a voltage is received at the input pin, whether the voltage is within a normal signal voltage range, enabling the performing of a primary function if the signal voltage is within a normal signal voltage range, and initiating an alternate function when the voltage is outside of the normal signal voltage range.

Abstract: The invention concerns a cooling and molding water tank for a plastic complicated profile. A plurality of molding blocks and water collection plates are provided along the length inside the tank, and they are spaced each other. The advantage of this invention is that: the cooling water flows alternately in cycle or periphery-inner-periphery. It makes the complicated profile cool homogeneously and efficiently upon the high speed extrusion pulling and provides the profile with good molding effect and quality.
