  • Patent number: 11511947
    Abstract: An overhead sweep rejecter (16) removes an object from a conveyor belt of a conveyor line. The rejecter has a kicker portion (22) that suspended for limited rotation about a pivot axis (40) from the housing. When a horizontal impulse is applied to the kicker portion by a rod (52), the limited rotation converts the impulse into a combination of vertical and horizontal impulses on the object, as would be provided by a pendulum. However, a contacting plate (34) on the kicker portion is pinned at a lower end (64) to a pair of guide rails (30) so that a vertical separation of the lower end remains at a constant vertical separation above the conveyor belt during rotation.

  • Patent number: 10025555
    Abstract: Devices and methods for detecting the byte order (endianness) of a control device with which a peripheral device will exchange data. The control device initially transmits a special byte order determination data command to the peripheral device, which data command includes both a byte sequence having a byte order that can be read in any direction and still have the same value, and a specific data value that is known to both the control device and the peripheral device. Control device byte order is subsequently revealed by using the peripheral device to analyze the data value of the byte order determination data command in each of several possible byte orders to determine which byte order format results in a return of the expected specific value.
