摘要： A power cut detection and recovery system (36) provides for the recovery of an electronic apparatus (20) in response to a momentary interruption in the voltage level of a power supply (46) coupled to that apparatus. The system includes a level detecting circuit (80) coupled to the power supply (46) for monitoring the voltage supplied to the apparatus (20). The system further includes internal reference supply circuits (86) that provide voltage and current references to operate the apparatus (20). A power cut monitor and reference control circuit (84) is coupled to the level detecting circuit (80) and is capable of causing the internal reference supply circuits (86) to remain enabled upon the detection of a momentary cut in the externally supplied power (46). A second level detecting circuit (90), dependent on the internal reference supply circuits (86), and the power cut monitor and reference control circuit (84) are coupled to an under voltage monitor and recovery circuit (88) that can cause the apparatus (20) to restart upon the recovery of the voltage level to a value above a predetermined level. By maintaining the internal reference supply circuits (86) in an enabled state, the apparatus (20) is able to restart in its pre-interruption state if the voltage level remains above a POR level.

摘要： A system, e.g. an integrated circuit or part, may include a plurality of pads, e.g. digital I/O pads, each comprising a physical pad and associated pad circuit. In case of an ESD event affecting one or more of the digital I/O pads, PMOS devices configured in an output buffer section between an I/O pad supply rail and the physical output pad—within their respective pad circuits in the affected digital I/O pads—may all be turned on in response to the ESD event. This may allow the capacitance of each pad, in some cases approximately 3 pF capacitance per pad, to charge up, absorbing the energy of the ESD event and reducing the peak voltage the integrated circuit or part experiences as a result of the ESD event. The reduced peak voltage may be directly correlated with improved ESD performance of the product.

摘要： An apparatus and method for reducing particles in reactors. The apparatus includes an enclosure for processing the semiconductor wafers. The enclosure has a wafer handling chamber connected by an isolation gate valve to a processing chamber. Additionally, the apparatus includes pipes for delivering a purge gas into the wafer handling chamber. The purge gas is used to eliminates particles from the enclosure. The apparatus also includes a pilot operated back pressure regulator for regulating the delivery and removal of the purge gas from the enclosure. The apparatus actuates the isolation gate valve in a controlled rate to reduce disturbances from the purge gas entering into the enclosure. The apparatus also includes a Bernoulli wand for lifting and holding a single semiconductor wafer. A dome loaded regulator is used to control the ramp rates of the gas to the Bernoulli wand. The dome loaded regulator is actuated by a pilot gas. The ramp up and ramp down rates of the Bernoulli wand gas can be control by a multitude of restrictions and check valves in the pilot gas line. The apparatus also utilizes ionizers in the purge gas lines entering the wafer handling chamber and load locks. Through the use of an alpha particle emission source in the purge gas line prior to the load lock and wafer handling chamber, the purged gas molecules are ionized. The ionized gas is conductive and therefore discharges all static inside the semiconductor equipment. By removable of the static charge particle and wafers are no longer attracted to each other by electrostatic force. In addition, the apparatus includes means for reducing gas flow turbulence when switching valves within the reactor.

摘要： A method for transparent, online raffles is disclosed. The method provides for users to set up and hold online public raffles and solicit participants to join. Participants purchase unique tickets that are non-fungible tokens (NFTs) on a block chain. The web-based platform allows every participant to view their NFTs within the block chain's smart contract to promote fairness and transparency. The block chain also automates the random winner process, invitations, notifications and reward allocations amongst the stakeholders. An object of the invention is to provide a simple method to allow users to hold legitimate raffles online.

摘要： A device and a system operative for protecting an automobile door from dent and damage to the finish. The device has a shield that stows in a chamber in an automobile frame below an automobile door, the shield deploying upwardly from the chamber to a position adjacent to the automobile door. The shield is deployed by a hydraulic system coupled to the shield through a plurality of linkages on a track that deploys the shield out the chamber opening and retracts the shield into the chamber. The system has an actuator for actuating the hydraulic system, the actuator selectively actuating the hydraulic system to deploy the shield when the door is locked and selectively actuating the hydraulic system to deploy the shield when is door is opening. A remote control device actuates the hydraulic system in one example embodiment. A sensor actuates the hydraulic system in another example embodiment.
