摘要:
Various examples are directed to systems and methods for managing a sensor. A measurement system may receive, from a host device, a first register map describing a first configuration of a measurement system. The first configuration may be associated with a first sensor. The measurement system may compare the first register map to an error rule set indicating inconsistent register map arrangements. After comparing the first register map to the error rule set, the measurement system may configure a switch matrix of the measurement system to sample the first sensor according to the first configuration of the measurement TO system. The measurement system may receive a plurality of samples from a first sensor and generate first digital measurement data based at least in part on the plurality of samples.

A digital filtering system is fed by input signal and produces an output signal from either a relatively low bandwidth filter or a relatively wide bandwidth filter selectively in accordance with the time rate of change in the input signal. The output signal is produced by the relatively low bandwidth filter when the input signal is slowly varying and the output signal is produced by the relatively wide bandwidth filter when the input signal changes rapidly, after which the output is produced from the relatively low bandwidth filter when the input signal reverts to its more slowly varying characteristics.

The present invention relates generally to card games and specifically, card games played for monetary gain in casinos. The game is an improvement over the traditional method of playing Blackjack or “21” in that it adds an incentive for a player to make a supplemental wager that also effects the betting strategy of the player. The supplemental wager will pay bonus money based on the value of the cards received from the dealer at the conclusion of the game.
摘要:
A method of computational fluid dynamic modelling of a subterranean region comprises: defining a computational domain by generating a geometrical model of a subterranean region comprising a wellbore and a surrounding formation; associating knowledge of a physical property of the subterranean region with a computational parameter; and inputting the computational parameter into the computational domain. In one embodiment knowledge of permeability within the subterranean region is defined as a viscous resistance within the computational domain.

An apparatus for sorting mail includes at least one tier of mail receiving receptacles (12) arranged in an arcuate configuration. The preferred embodiment utilizes an arm (16) supported by a support (14) for pivotal movement about a substantially vertical pivot axis (22). The arm sweeps in an arc in close proximity with and conforming to the arcuate configuration of the tier of mail receiving receptacles (12). A conveyor (24) conveys individual pieces of mail (26) sequentially along the arm. A controller (36) is provided which is adapted to monitor the positioning of the arm (16) relative to the tier of mail receiving receptacles (12), selectively activate a drive motor (30) to alter the positioning of the arm (16), and selectively activate the conveyor (24) to convey individual pieces of mail (26) sequentially along the conveyor to the second end of the arm and into selected mail receiving receptacles. The apparatus provides a significant sorting capacity within a relatively compact space.
摘要:
A smoke alarm device has an ASIC (1) with an integrated photo detector (3) and control circuit. The photo detector output is compared every ten seconds with an alarm threshold level in a comparator circuit (10), with a sensitivity-decrease threshold in a comparator circuit (11), and with a sensitivity-increase threshold in a comparator circuit (12). A logic block (2) causes sensitivity to be increased or decreased in which decreases take place at intervals of six hours and increases take place after 40 secs. The logic block (2) provides for least sensitivity at power-up with rapid increases to the appropriate level according to the level of back-scatter caused by dust contamination. The logic block (2) maintains a high signal on an interconnect terminal (9) for four seconds after a test button (7) is pressed so that a maintenance person can hear remote interconnected devices after the local device has stopped sounding. The logic block (2) also stores a memory flag when is goes into alarm mode and modulates the horn at a different frequency at the next testing to indicate that it has historically sensed smoke since last tested.
摘要:
A support arrangement for readily mounting the diaphragm of a piezoelectric transducer on a desired node ring, the diaphragm having coaxially mounted thereon a circular piezoelectric element having a diameter substantially the same as that of the node ring. The diaphragm is axially clamped on the node ring between first and second support members. The first support member includes first locking means extending therefrom into engagement with the second support member to axially lock the first and second support members together, and the second support member includes second locking means extending therefrom into locking engagement with the first locking means to lock the first locking means in engagement with the second support member.
