摘要： A fiber optic GPS signal device and method comprising a VCSEL multimode transmitter having a gain that, together with the GPS antenna gain, is greater than the VCSEL multimode transmitter noise. When in operative communication, via a long length of multimode fiber, i.e., up to 2000 feet and greater, with a fiber optic receiver, the GPS signals are transmitted at, inter alia, L1 and L2 frequencies with minimal degradation over the length of multimode fiber. The present invention may be used in a variety of GPS transmission applications requiring long lengths of cabling. For example, the invention is particularly useful when the GPS antenna is located on top of an office building or cell phone tower and remotely from the GPS receiver and for use in high-volume commercial telephone synchronizing (DTMF) applications.

摘要： A system and methods for controlling adjustable furniture 60. The adjustable furniture 60 may be controlled by a control unit 34 in communication with a remote controller 40. A user may input commands to the remote controller 40 through a manual input device 42 or a microphone 43. The control unit 34 may be operable to adjust at least one actuable device element 28a-d, 32a-d, 52a, 52b in response to the commands. The adjustments of actuable device elements 28a-d, 32a-d, 52a, 52b may be measured by a sensor 58 that generates a sensor signal operable to be analyzed by the control unit 34 to determine an execution status of the command. The execution status may be indicated on the remote controller 40 by a speaker 44 or a display 45. The control unit 34 may also be operable to send signals for the remote controller 40 to make a noise.
