  • Patent number: 11989379
    Abstract: A sensor controller is provided for use in a position detector for detecting a position of a position indicator on a touch surface. The sensor controller includes a microprocessor for outputting a value of a symbol to be sent to the position indicator. The sensor controller includes a transmitter coupled to the microprocessor for generating a transmission signal including a chip string CN1 produced by cyclically shifting a code string PNa having autocorrelation characteristics by a shift quantity based on the value of the symbol to be sent, and sending the generated transmission signal to the position indicator via the touch surface. A higher bit rate can be obtained for a given chip rate compared with the prior art in which only 1 bit can be expressed by one code string.

  • Publication number: 20240096235
    Abstract: An information processing apparatus (1) included in a welding training system includes a transmittance adjuster (14) capable of adjusting a transmittance of a window of a welding helmet in virtual space in multiple grades, and a display controller (17) configured to cause a display of an HMD (2) to display a situation of a welding operation in the virtual space at an illuminance corresponding to the adjusted transmittance. The transmittance adjuster (14) adjusts the transmittance based on a skill level of a trainee determined by a skill level determination unit (13).

  • Publication number: 20240077960
    Abstract: A pen-shaped position indicator is configured to capacitively couple with a sensor surface of a position detection apparatus. The indicator includes a pen-shaped body; a coil; a driving power production circuit configured to produce a DC voltage from an induced signal in the coil by a wireless interaction with a charging device; a signal production circuit connected to the driving power production circuit and configured to generate a signal based on the DC voltage to form a capacitive relationship between the pen-shaped body and the position detection apparatus; a first electrode; and a second electrode. The first and second electrodes are configured to form first and second capacitive relationships with the sensor surface, respectively, to generate detection signals in the sensor surface from which a first detection signal and a second detection signal distinguishable from each other are extracted and used to obtain angle information of the pen-shaped position indicator.

  • Patent number: 11915924
    Abstract: A recess is formed in one silicon substrate. A silicon oxide film is formed in another one silicon substrate at a portion space apart from a space-to-be-formed region. The silicon oxide film has a groove surrounding the space-to-be-formed region and extending to an outer periphery of the other one silicon substrate. Further, the other one silicon substrate and the one silicon substrate are directly bonded to each other via the silicon oxide film so as to cover the groove. A gas discharge passage, a stacking structure of the silicon substrates and the silicon oxide film are formed, and the space is formed inside the stacking structure by the recess. Then, by the heat treatment, the gas inside the space is discharged to the outside of the stacking structure through the gas discharge passage.

  • Patent number: 11840282
    Abstract: A work vehicle includes a hood swingable in an up-down direction between an open position, in which the hood is positioned expose an engine room, and a closed position, in which the hood is positioned to close the engine room, and at least one damper to urge the hood toward a side of the open position. The damper is swingable in the up-down direction to rise toward a standing position in response to the hood being swung from a position closer to the closed position toward a position closer to the open position and fall toward a lying position in response to the hood being swung from the position closer to the open position to the position closer to the closed position. An urging mechanism is provided to, while the damper is in a position closer to the lying position than an intermediate position, apply to the hood an urging force to urge the hood from the position closer to the closed position toward the position closer to the open position against the load of the hood.
