A method is provided for designing a product. The method may include obtaining data records relating to one or more input variables and one or more output parameters associated with the product and selecting one or more input parameters from the one or more input variables. The method may also include generating a computational model indicative of interrelationships between the one or more input parameters and the one or more output parameters based on the data records and providing a set of constraints to the computational model representative of a compliance state for the product. Further the method may include using the computational model and the provided set of constraints to generate statistical distributions for the one or more output parameters. The one or more input parameters and the one or more output parameters represent a design for the product.

摘要:
Geese and swans are repelled by applying methyl anthranalate or dimethyl anthranalate to their habitats or to pelleted agricultural chemicals lethal to geese or swans. With regard to applying the repellent to habitats, preferably the repellent is encapsulated in a starch-based material that is water tolerant and provides time release of the repellent.
摘要:
A police restraint device utilizing the principle of the second class lever and method of making the device, the device in its disclosed form comprising a presently preferred arm clamp having two rigid elongated handles or sticks, adapted to be held and manipulated manually, with a single strong flexible cord or rope of predetermined length spanning between and integrally joining the distal ends of the handles one to the other. Each end of the cord is snugly enclosed within a crimped metal cap or sleeve which in turn is snugly inserted in a blind bore at the distal end of the associated stick and pin-secured in that position.

This disclosure relates to a system and method for detecting sensor failure and controlling a machine. The system includes a plurality of physical sensors, an electronic control module operably connected to the plurality of physical sensors, and a data storage unit operably connected to the electronic control module. The electronic control module is configured to retrieve calibration data associated with a plurality of input parameters, obtain a set of values of the plurality of input parameters, calculate a Mahalanobis distance of the set of values of the input parameters based on the calibration data, increment an evidence score of an input parameter if the Mahalanobis distance exceeds a threshold Mahalanobis distance value; and command a machine action when the evidence score of an input parameter exceeds an threshold evidence score value.
摘要:
A support (10) for moving an object between two locations. The support (10) has one or more elongate members (12) upon which a platform, such as a seat (50), can be slid. The elongate member (12) has a guide rail (15) which has two flanges (17) each terminated with an arcuate groove (18). The flanges (17) and the arcuate grooves (18) form a track (22) in which wheels (24) of the seat (50) can run.Typically, the support (10) is used for moving the seat (50) into and out of a shower recess or over a bath for the bathing of the aged and invalids. The guide rail (15) can also be used as a curtin track, a track for a sliding panel and the like.
