November 14, 2006. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3609579 Method and apparatus for transmitting intelligence over a carrier wave Frequency multiplexed radio link apparatus Channel selector having a plurality of tuning systems Diversity receiver Broadband injection locked oscillator system Interactive non-hierarchical adaptively synchronized oscillator network and phase locked loop oscillator for use therein Cordless telephone Phase adjustment system Patent #: 4651103 InventorAssigneeApplicationNo. 06/931338 filed on 11/14/1986US Classes:455/500, Plural transmitters or receivers (i.e., more than two stations)455/208, With synchronized or controlled local oscillator455/265, With local oscillator synchronization or locking455/317Unwanted oscillation or radiation preventionExaminersPrimary: Masinick, Michael A.Assistant: Kuntz, Curtis Attorney, Agent or FirmInternational ClassesH04B 5/00 (20060101)H04B 1/50 (20060101) H04B 1/40 (20060101) AbstractA proximal cable-less communication system employs the physical placement of the units to each other to achieve information transfer. Local oscillators of each of the receivers are modulated and this modulated signal containing intelligence is received by other receivers due to the leakage radiation from the local oscillators.Field of SearchTRANSMITTER AND RECEIVER AT SEPARATE STATIONSPlural receivers Selectively actuated or controlled Including common stage (e.g., local oscillator) Responsive to one of overlapping signals With synchronized or controlled local oscillator Plural local oscillators or mixers Local oscillator frequency control With local oscillator synchronization or locking Unwanted oscillation or radiation prevention Transceiver controlling a separate transceiver or receiver | |
