Abstract: The disclosed system may include a substructure configured to support various components, an actuator configured to provide substantially linear motion along a specified axis in response to an electrical input, an input component hingedly coupled to the substructure, where the input component is configured to receive input from a user, and a mechanical linkage coupled to the input component and to at least a portion of the actuator. The mechanical linkage may be configured to translate the substantially linear motion provided by the actuator to a rotary force applied to the input component via the mechanical linkage. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A hand-held controller includes a handle extending in a longitudinal direction. The handle is shaped and dimensioned to be grasped by a hand of a user. A ring is attached to an end of the handle and surrounds a thumb of the user when the handle is grasped by the hand of the user. The ring has an annular surface defining a plane that forms a predetermined angle with respect to the longitudinal direction. The ring also has a curved outer surface. A sensor is embedded within the ring or mounted on a side surface of the handle to detect whether the hand of the user grasping the handle is a right hand of the user or a left hand of the user.

Abstract: The disclosed handheld controllers may include a multi-degree of freedom sensor module, a mouse module, and a switch. The mouse module may include a mouse sensor and a proximity sensor. The switch may be configured to activate the mouse sensor and deactivate the multi-degree of freedom sensor module when the proximity sensor indicates that the mouse sensor is proximate to a physical surface and to deactivate the mouse sensor and activate the multi-degree of freedom sensor when the proximity sensor indicates that the mouse sensor is not proximate to the physical surface. Various other related methods, systems, and devices are also disclosed.

Abstract: A haptic skull cap provides different types of haptic feedback to a user, which can be advantageous for providing a more immersive virtual reality experience. The haptic skull cap includes a fabric cap worn by a user. Physically attached to the fabric cap is a linear actuator that provides a focal impact to a user's forehead. Additionally, vibrational motors are physically attached to the fabric cap, where each vibration motor provides vibrational feedback to a different location of the user's head. The haptic skull cap can be worn by a user in conjunction with a head mounted display. Therefore, each type of haptic feedback provided by the haptic skull cap can be synchronized with the visual data stream provided by the head mounted display which further enhances the overall virtual reality experience for a user.

Abstract: A stylus may include an elongated housing, at least one sensor that is configured to detect manipulation of the stylus by a user, and a tracking component that enables the stylus to be tracked in a virtual, augmented, or mixed reality environment. A corresponding head-mounted display system may include a stylus with an elongated housing and a tracking component, a tracking subsystem that is configured to track manipulation of the stylus using the tracking component, and a display subsystem configured to display the manipulation of the stylus within a virtual, augmented, or mixed reality environment. A related method of assembling a stylus including coupling at least one sensor to an elongated housing and coupling a tracking component to the elongated housing.

Abstract: The disclosed apparatus may include a support structure that holds a portion of the apparatus in physical contact with a user's fingertip, a feedback mechanism that provides tactile feedback to the user's fingertip, a position tracking element that facilitates tracking the position of the user's fingertip, and a communication component that facilitates communication between the apparatus and a control device. Various other apparatuses, systems, and methods are also disclosed.

Abstract: In the present invention a method and circuit are shown to protect flash memory from data corruption during a rapid power down. A circuit element detect the drop in power voltage and signals that any write operation being performed be switched into a programming phase, and at the same time increase the programming voltage to the flash memory to significantly reduce programming time. If the power drop occurs during an erase phase of a write operation, the erase operation is switched to a program operation using old data to program erased cells. If the power drop occurs during a programming phase of the write operation, the programming phase is continued but at a faster rate.
