Abstract: A protocol may be implemented in a smart transceiver device that contains the physical (PHY) and media access control (MAC) layers of a protocol stack. In various embodiments, a serial peripheral interface (SPI) based design may be used. A protocol is disclosed that may be used to provide control and data transfer to and from the smart transceiver device. In particular, an exemplary format for the protocol, the commands, and responses is disclosed. In a further embodiment, a method for mode synchronization that does not require the use of additional pins and can be accomplished with the standard SPI pins is disclosed. In another embodiment, a method that permits frame timing on the SPI bus to be restored without resetting the slave device is disclosed.

Abstract: A hand-held input device provides a directional force feedback that acts on a housing of the device. The input device includes a threaded shaft that is rotatably driven by an electric motor. The motor causes a mass to move in response to a control signal received from a host computing device, such as personal computer that is executing a game or simulation. When the mass is rapidly accelerated or abruptly stopped in response to the control signal, the change in momentum of the mass imparts a directional reactive force to the housing, and an operator holding the housing feels the haptic force.

Abstract: A joystick produces a control input signal in response to a pivotal displacement of a control handle about any of a plurality of axes. Corrected signals for each of orthogonal “X” and “Y” axes are provided in response to a pivotal displacement of the control handle about a center point disposed within a housing. Rotation of the control handle about the center point is enabled through use of a pair of members having spherical exterior surfaces sharing a common center. The member includes a hemispherical-shaped shell coupled to the control handle shaft, and an end cap defining a spherical surface disposed at the end of the control handle shaft. The control handle shaft extends into the housing through an opening defined in an upper portion of the housing. The opening provides a bearing surface adapted to slidingly engage the spherical upper surface of the hemispherical-shaped shell. The housing further includes a lower portion with a receiver adapted to slidingly engage the end cap.
