  • Patent number: 11205234
    Abstract: A farm sensing system is provided. The farm sensing system includes a cloud server, a sensing apparatus, and a computer device. The sensing apparatus is configured to be connected to a specific sensor disposed on a farm. The computer device is configured to obtain specific sensor data generated by the specific sensor through the cloud server. In response to there being potential failure of the specific sensor, the sensing apparatus enters a sensor-calibration mode. In response to a reference sensor being connected to the sensing apparatus, the sensing apparatus builds a calibration table by periodically receiving specific sensor data and reference sensor data, and executes a finite-state machine to perform a calibration procedure on each entry in the calibration table.

  • Patent number: 11097184
    Abstract: A game controller includes a joystick that accepts end user inputs and has illumination provided at the game controller surface encircling the joystick to provide indications to an end user, such as a locally-determined game controller status or a game application end user energy state. The illumination is provided from light emitting diodes disposed within the game controller interior on a flexible printed circuit board and coupled to a base of an annular light guide by a gasket to direct illumination into the annular light guide. Non-translucent treatment at the light guide on the game controller surface defines a translucent region at which illumination is presented.

  • Publication number: 20210197079
    Abstract: A game controller has first and second controller housings having an attachment guide structure that detachably couples to an attachment tab structure disposed on opposing sides of an information handling system and a bridge. Input devices of the controller housing communicate directly with the information handling system through opposing pins and pads disposed in the attachment features or indirectly by communicating with the bridge through opposing pins and pads so the bridge communicates with the information handling system. The attachment guide structure has opposing lips with plural slots that pass tabs of the attachment tab structure through so that a sliding motion engages the tabs behind the lips.

  • Publication number: 20210197077
    Abstract: A game controller integrates a trigger at a side of a planar controller housing, the trigger rotating within the plane of the controller housing about an axle disposed perpendicular to the plane. The trigger rotationally couples to the axle at a trigger bracket that fixedly coupled to a frame. A guide integrated in the frame engages a member extending from the trigger to manage trigger motion. A cover couples to the frame and separate from the trigger to enhance housing robustness.
