  • Patent number: 10677614
    Abstract: Provided is an encoder that can sense an abnormality in the attitude of a detector with respect to a scale. An encoder includes a scale and a detector, the scale being provided on one measurement target part with marks arranged on the scale, and the detector being provided on another measurement target part and configured to detect an amount of relative movement with the scale. The scale includes a sensing unit that senses the attitude of the detector with respect to the scale, and thus even in a case where an abnormality in the attitude of the detector with respect to the scale cannot be sensed on the basis of a change in a signal read by a reading unit, the abnormality can nevertheless be sensed.

  • Patent number: 10634521
    Abstract: Disclosed embodiments include a two-dimensional scale with a simple arrangement capable of omitting setting of an origin mark in the Y-axis direction. In a linear scale, a reference origin mark array and a tilting origin mark array that is a tilting marker array are provided in an origin mark region. Since the reference origin mark array is parallel to X-coordinates, an X-direction origin signal is correctly generated. On the other hand, for the Y direction in which no origin mark is provided, the distance between a reference origin mark and a tilting origin mark is detected. A Y-direction absolute position is decided in accordance with the distance.

  • Patent number: 10631389
    Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space.

  • Patent number: 10605632
    Abstract: A dual-threaded bushing and spacer assembly capable of accepting standard adhesive staking and thereby enabling compliance with NASA space flight fastener staking requirements. The assembly comprises a bushing having a head with top and bottom surfaces, inner threads, and outer threads, and a spacer having top and bottom surfaces and arranged to accept the bushing. This is achieved by providing a counterbored countersink in the spacer which provides a countersunk surface within the spacer. The countersunk surface provides a contact surface for the bushing head's bottom surface when the bushing is installed in the spacer. The spacer is further arranged such that the countersunk surface is such that, when the bushing is installed, the bushing's top surface is below the spacer's top surface. When so arranged, adhesive staking can be placed between the bushing's top surface and the spacer's vertical counterbored surface.
