摘要： A transcription module having a mounting unit, acoustical receivers and an EM detector is disclosed. The mounting unit is adapted for positioning the transcription module over a work surface. First and second acoustical receivers are attached to the mounting unit. Each acoustical receiver includes a microphone positioned over a corresponding location on the work surface. Each microphone views the work surface at the corresponding location and is configured to receive acoustical signals from an input device operating over the work surface at another location. The EM detector detects an EM signal that is synchronized with the acoustical signals.

摘要： An acoustical receiver for detecting an acoustical signal characterized by a wavelength and a pen transcription system utilizing the same are disclosed. The receiver includes a detector that generates an electrical signal in response to acoustical signals in a predetermined frequency range including that wavelength, a housing surrounding the detector, and a receiving horn. The housing has a housing aperture having a maximum dimension less than the acoustical signal wavelength. The receiving horn has a first opening that is adjacent to the housing aperture and a second aperture having a dimension that is greater than the acoustical signal wavelength.

摘要： A pen transcription system and method for using the same are disclosed. The pen transcription system includes a receiver having first and second acoustical sensors mounted on a planar base and separated from one another, an EM detector, and a controller. The first and second acoustical sensors detect an acoustical signal at a first wavelength emitted by a moveable signal source. The EM detector detects an EM signal that is synchronized with the acoustical signal. The controller measures the difference in time of detection between the EM signal and the acoustical signals detected by the first and second acoustical sensors. The acoustical sensors include a detector and a housing surrounding the detector, the housing having an aperture having a maximum dimension that is less than the first wavelength divided by 6.28.
