A system providing tactile sensations. The system comprises a seat back of a seat, the seat back having a left side and a right side separated by a center-line of the seat back. A first plurality of electroactive transducers are arranged along the center-line of the seat back and provide tactile sound to a user. A second plurality of electroactive transducers in the seat back provide tactile alerts or feedback. The second plurality of electroactive alert transducers comprise a left-side electroactive transducer at the left side of the seat back and right-side electroactive transducer at the right side of the seat back.

Real-time field data that is associated with a hydrocarbon reservoir drilling field is obtained. A carrying capacity index (CCI) and a cutting concentration annulus (CCA) are determined based on the real-time field data. In response to determining the CCI and CCA, the CCI is compared with a first predetermined value and the CCA is compared with a second predetermined value to obtain a comparison result. One or more parameters associated with the hydrocarbon reservoir drilling field are adjusted based on the comparison result through a user interface (UI).

A delivery device comprising an acquisition mode for activating at least one button for controlling the delivery of a drug.

A liquid metal leak detector system including a direct current (DC) power supply and a plurality of analog to digital converters connected to the DC power supply. Each converter includes a liquid metal switch, where the liquid metal switch is closed in event of a liquid metal leak since the liquid metal leak causes electrical continuity between a conductive sheeting and a housing for liquid metal. The converter also includes a comparator connected to both the liquid metal switch for converting an analog signal into a digital signal, wherein the digital signal is configured such that a high signal constitutes no leak and a low signal constitutes a leak. An AND gate is also connected to each of the plurality of converters for combining all of the digital signals output from the converters, the AND gate configured such that the AND gate outputs a high signal if all of its inputs are high and a low signal if any input is low.

A construction site status monitoring device is provided including processing circuitry configured to receive sensor data from a sensor associated with one or more construction devices, receive location data associated with the one or more construction devices, and generate a construction site status report based on the sensor data and the location data, wherein the construction site status report is indicative of conditions and location of the one or more construction devices.

A programmable logic controller system has: an input unit system section in which plural input units are combined; a CPU unit system section in which plural CPU units are combined; and an output unit system section in which plural output units are combined. Each system section has: a setting retaining unit to retain a setting indicating whether to use any of the plural units alone or use the plural units in a multiplexed manner; and a comparing unit to make a comparison of processed data between the plural units when the setting indicates using the plural units in a multiplexed manner, to send the processed data if the comparison result indicates consistency, and to perform an error process if the comparison result indicates inconsistency. In the setting retaining unit, whether to use alone or in a multiplexed manner is set based on an externally-input setting instruction.
