Title: Automated calibration adjustment for film dosimetry
Inventor: RITT DANIEL M
IPC: G01T1/08
Filed: 2001-01-09
Abstract: The present invention provides a method of correcting errors in film dosimetry measurements arising from variations in radiographic film processing and manufacturing. The method includes: (1) irradiating separate and distinct areas of one or more calibration films with different radiation dose levels to obtain a first calibration; (2) exposing a non-irradiated portion of at least one (and typically all) of the calibration films to light from an array of standardized light sources to obtain a first optical density step gradient; (3) exposing a non-irradiated portion of subsequent test films to light from the array of standardized light sources to obtain a second optical density step gradient; and (4) modifying the first calibration or optical density values of the test films based on differences between the first and second optical density step gradients.  Since the characteristics of each of the standardized light sources vary little from one exposure to the next, any deviations in the optical density step gradient among different films results, presumably, from changes in film processing or differences in film chemistry.

Title: Method for controlling a transmission system, use of this method, transmission system, receiving unit and hearing aid
Inventor: CONSTANTIN JEAN-CLAUDE
IPC: H04R3/00
Filed: 2000-09-18
Abstract: The invention relates first to a method for controlling a transmission system consisting of at least one transmitter (S1,... Sn) and at least one receiving unit (1), a signal (SIN) that is transmitted through a service channel (120) being amplitude-, frequency-, and/or phase-modulated. According to the invention, configuration parameters are transmitted to the receiving unit (1) through a control channel (110,, 113). This transmission through the control channel (110,, 113) takes place independently of any transmission that may have taken place through the service channel (120). Based on the configuration parameters that are transmitted, adjustments relating especially to the demodulation of the signal (SIN) that is transmitted through the service channel are made in the receiving unit (1). The invention also relates to an application for the method, to a transmission system, to a receiving unit and to a hearing aid.
