  • Publication number: 20260145058
    Abstract: Space inside a handheld game controller can be limited, making it difficult to add a new or different user input device without increasing the overall size of the handheld game controller. The embodiments provided herein describe user input devices configured for use in such a space-constrained environment. In one embodiment, a cantilevered button is used when a component inside the handheld game controller is positioned in a path between the button and a switch. In another embodiment, an opening is made in a circuit board inside the handheld game controller to allow a joystick assembly to pass through the circuit board. Other embodiments are disclosed, and each embodiment can be used alone or in combination with other embodiments.

  • Publication number: 20200346407
    Abstract: A processing machine (10) for building a part (11) includes: a support device (26) including a support surface (26B); a drive device (28) which moves the support device (26) so as a specific position on the support surface (26B) is moved along a moving direction (25); a powder supply device (18) which supplies a powder (12) to the moving support device (26) to form a powder layer (13); an irradiation device (22) which irradiates at least a portion of the powder layer (13) with an energy beam (22D) to form at least a portion of the part (11) from the powder layer (13) during a first period of time; and a measurement device (20) which measures at least portion of the part (11) during a second period of time. The first period in which the irradiation device (22) irradiates the powder layer (13) with the energy beam (22D) and the second period in which the measurement device (22) measures are overlapped.

  • Patent number: 10451982
    Abstract: An actuator assembly (16) for moving a device (22) includes a stator component (30), a mover component (32), a measurement system (18), and a signal processor (20). The measurement system (18) includes (i) a magnet assembly (244) that is coupled to and moves with the mover component (32); and (ii) a plurality of spaced apart sensors (246A). The magnet assembly (244) produces a magnetic field (244B) that moves relative to the stator component (30) as the mover component (32) moves along a mover axis (32C). Each sensor (246A) is a transducer that generates a sensor signal that varies its output voltage in response to the changing magnetic field (244B) from the magnet assembly (244) as the mover component (32) is moved relative to the sensors (246A). The signal processor (20) receives the sensor signals and estimates a position of the mover component (32) along the mover axis (32C) based at least in part on the sensor signals.

  • Patent number: 10259104
    Abstract: A clamp for selectively inhibiting movement of a first object relative to a second object includes (i) a first clamp component coupled to the first object; (ii) a second clamp component coupled to the second object; and (iii) a fluid source that directs a fluid to the second clamp component to create a fluid bearing between the first clamp component and the second clamp component that allows for movement of the first clamp component relative to the second clamp component, and wherein the fluid source directs less fluid to the second clamp component to inhibit relative movement.
