A programmable controller system includes a programmable controller apparatus, a remote input and output apparatus connected to the programmable controller apparatus via a field bus and a monitoring apparatus configured to be located on a communication path between the programmable controller apparatus and the remote input and output apparatus and to monitor a communication data therebetween. The monitoring apparatus includes a rewritable tag for prescribing a condition for issuing a transmission request command with respect to an external equipment deterioration diagnosis and a command issuing part issues a transmission request command required for the external equipment deterioration diagnosis with reference to the tag. A preferable data logging operation is carried out properly without any PLC operation.

An input circuit for a semiconductor integrated circuit in which an operational state is constant even when a process condition, a temperature, a voltage, and the like are varied at the time of operation is provided. The input circuit includes a first input unit that performs a first amplifying operation on a potential difference between a reference voltage and an input signal and outputs a result of the amplification, and a second input unit that performs a second amplifying operation on a signal amplified by the first input unit and outputs a result of the amplification.

A liquid separator system having a gas phase zone, an aqueous phase zone and a denser liquid zone is used to separate mixtures of fluids. The separator can be used for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet. The interface control structure is adjusted to optimally alter the vertical height of the interface level within the vessel so that the residence time of the molten sulfur in the vessel does not decrease as the sulfur production throughput decreases, and so that the interface area of the molten sulfur and the redox solution is reduced as the sulfur throughput decreases. A pressure controller monitors the pressure in the vessel and adds or removes gas from a gas phase zone in the vessel to maintain a predetermined pressure regardless of the vertical height of the interface.

Aspects disclosed include static random access memory (SRAM) arrays having substantially constant operational yields across multiple modes of operation. In one aspect, a method of designing SRAM arrays with multiple modes operation is provided. The method includes determining performance characteristics associated with each mode of operation. SRAM bit cells configured to operate in each mode of operation are provided to the SRAM array. SRAM bit cells are biased to operate in a mode of operation using dynamic adaptive assist techniques, wherein the SRAM bit cells achieve a substantially constant operational yield across the modes. The SRAM bit cells have a corresponding type, wherein the number of SRAM bit cell types in the method is less than the number of modes of operation. Thus, each SRAM array may achieve a particular mode of operation without requiring a separate SRAM bit cell type for each mode, thereby reducing costs.

Systems, apparatuses, and methods for reducing latency for wireless virtual and augmented reality applications are disclosed. A virtual reality (VR) or augmented reality (AR) system includes a transmitter rendering, encoding, and sending video frames to a receiver coupled to a head-mounted display (HMD). In one scenario, rather than waiting until the entire frame is encoded before sending the frame to the receiver, the transmitter sends an encoded left-eye portion to the receiver while the right-eye portion is being encoded. In another scenario, the frame is partitioned into a plurality of slices, and each slice is encoded and then sent to the receiver while the next slice is being encoded. In a further scenario, each slice is being encoded while the next slice is being rendered. In a still further scenario, each slice is prepared for presentation by the receiver while the next slice is being decoded by the receiver.

An un-pressurized chlorination device comprises a container having an open top closed by a removable lid. The container defines an inner chamber for a plurality of chlorination tablets. The container has a lower inlet spigot for receiving a water supply inlet pipe. The container also has a lower water outlet through which chlorinated water is delivered. There is a water flow path between the inlet and the outlet. The tablet chamber is not pressurized and the outlet discharges to atmosphere pressure. The device of the invention is useful for dissolving, dispersing and dispensing soluble material in tablet form into a liquid. There is a substantially horizontal fluid path with just enough fall to the outlet to allow the device to drain down out of the outlet when there is no inlet flow.
