Abstract: A safety module having a plurality of microcontrollers receives an analog input and determines a value of the analog input. The microcontrollers each determine a respective ternary state of the device by identifying, from three candidate ranges of values, a range of values in which the value falls, wherein at least two of the plurality of microcontrollers uses different candidate ranges of values, determining, based on the identified range, a ternary state corresponding to the range, and assigning the determined ternary state as the respective ternary state. The safety module determines whether the ternary states from the two microcontrollers map to a fault state, and, where they do, cause a command a command to be output to the device to enter a safe state.

Abstract: A continuously variable transmission in which a circular driver, positioned between and frictionally engaged with op posing surfaces of two oppositely rotatable disks, which are urged towards each other with a biasing mechanism, is mounted to, and is movable axially along, a drive shaft which extends radially from an input shaft which rotates the drive shaft about a longitudinal axis of the input shaft, and wherein output drive is taken from the disks via a speed balancing system.

Abstract: Disclosed is a mechanically operational arrangement for continuously variable transmission, comprising a central shaft (1), wherein a toothed groove section (8) is circumferentially arranged in a middle portion of an external surface of the central shaft (1); wherein a shaft sleeve (9) is fitted over the external surface of the central shaft (1); wherein a plurality of axial limiting grooves (10) are provided on an external surface of the shaft sleeve (9); wherein inserted into each axial limiting groove (10) is a connecting plate (6); wherein an arc-shaped toothed wheel section (7) is arranged on an inner end face of each connecting plate (6); wherein each of the arc-shaped toothed wheel sections (7) is meshed with the toothed groove section (8); wherein a pivot (11) is mounted in a side face of each connecting plate (6); and wherein each connecting plate (6) is respectively hinged to a groove wall of one axial limiting groove (10) via the respective pivot (11).

Abstract: One of a first signal, a second signal, and a third signal is received respectively from each of three inputs. A pattern formed by the first signal, the second signal, and the third signal is compared to a set of predetermined patterns. Based on the comparing, it is determined whether an error exists. If an error condition exists, a specific one of the inputs is identified as a cause of the error.

Abstract: A toroidal-type continuously variable transmission has a casing, a rotation shaft, a pair of outer side disks having a side surface, supported on the rotation shaft, and rotating in synchronism with the rotation shaft, an inner side disk having two side surfaces, rotatably supported around a middle portion of the rotation shaft, and rotating relative to the rotation shaft, pluralities of supporting members disposed between the two side surfaces of the inner side disk and the side surfaces of the outer side disks, respectively, and swinging on a pivot shaft disposed so as to be twisted to the rotation shaft, and pluralities of power rollers rotatably supported on the respective supporting members, wherein an outer peripheral face of the inner side disk is provided with a detected portion for detecting rotation of the inner side disk.

Abstract: A transfer case motor controls the rotation of a cam. The cam actuates various gear states of a transfer case of a four-wheel-drive vehicle. A contact plate rotates with the cam and encodes the position of the cam as a four-bit binary code. The code is such that when the cam travels between any two gear states, one bit of the four-bit code stays constant from the initial gear state until the final gear state is reached. The single bit can thus be observed to determine that the final gear state has been reached. The encoding scheme is also such that the bit which stays constant always assumes the same state.
