Abstract: Example channel circuits, data storage devices, and methods for asynchronous sampling from an oversampled analog-to-digital converter are described. The channel circuit may include an analog-to-digital converter configured to generate an oversampled digital signal from an analog data signal using a sample rate that is an integer multiple of the baud rate of the channel circuit. A digital sample interpolator may then interpolate interpolated digital signal values from multiple signal values of the oversampled digital signal and select values at baud rate to generate a baud rate digital signal. The baud rate digital signal may be used by an iterative detector in a timing loop and, once a target timing is achieved, for the iterative detector to detect data bits from the interpolated digital signal.

Abstract: Techniques for locating and communicating with users of a platform are disclosed. A specification of a target user is received. A remote platform is queried for the target user and a result of the query includes a first user of the remote platform. A message is sent to the first user, on behalf of a second user, by an entity that is different from the second user.

Abstract: Connecting means for interfacing the end of an optic signal conduit and electric signal conducting means comprises an optic-electronic conversion element having a body adapted to receive optic signals and one or more electrically conductive leads, a first housing member having an elongated portion adapted to receive the body on its free end with the leads extended therealong, a second housing member adapted to receive the end of the optic signal conduit and the elongated portion of the first housing member with the body in communication with the end of the optic signal conduit, an elastomeric ring having axially extending layers of alternating electrically conducting and insulated elastomeric material, the ring surrounding the elongated portion with the conducting layers in contact with the leads, and a third housing member adapted to receive the first housing members with the elastomeric ring therebetween and further including contacts communicating with the electrical signal conducting means and adapted to

Abstract: Switching functions such as for windshield wiper control in a vehicle are remotely controlled by a manually positioned optical selector connected through a fiber optic conductor to an electro-optic transceiver. The transceiver provides a light source for illuminating the light conductor and the selector controls the positions of color coated mirrors which are selectively positioned to reflect color coded light via the light conductor to the transceiver which analyzes the modified light spectrum. A logic circuit responsive to the transceiver output controls actuators according to the selected switch function.
