International Classification:

H05K 7/00
H03F 3/45
H03F 3/68

US Classification:

36167901, 330124 R, 330 69

Abstract:

Techniques for amplifying a plurality of input voltages to generate a corresponding plurality of output voltages. In an exemplary embodiment, each of the plurality of input voltages is referenced to a common voltage comprising the average of the plurality of input voltages, without the need to reference an independently provided common voltage. In an alternative exemplary embodiment, techniques are provided for automatically measuring the input impedance between any two nodes corresponding to the plurality of input voltages. Further techniques are provided for coupling input nodes of the amplifier modules to a common reference voltage, and to the housing of the apparatus.

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.
