Title: Device for measuring substantially vertical, circular-cylindrical objects
Inventor: WIKLUND RUDOLF
IPC: G01B7/14
Filed: 1987-01-28
Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to an improvement of a hypsometer, with which one measures and computes the dimensions of circular cylindrical vertical objects, such as trees. In the sight of the hypsometer there is a horizontal angle device for determining the horizon-tal angular distance between the boundary surfaces of the object to be measured. A computing unit computes the diameter of the object at a location along its length at which the operator has aimed the instrument, on the basis of said angular distance and the distance to the object and the vertical angular position when aiming at this location, as obtained from the plumb-line angle sensor of the hypsometer.

Abstract: ABSTRACT          A programmable patient controlled master hearing' aid is disclosed which consists of a hearing aid test module 200, an operator's console 50 and a patient's console 45, both of which are microprocessor 59,77 based, and all of which are interconnected to provide a testing apparatus which is used by the patient to select electronic components to be employed in a hearing aid.  The testing device has selectable electronic components 110, 210, 212, C2, R1, R2, R3 that match the components which will be used in the hearing aid which the patient selects as best assisting or addressing the patient's hearing loss.  The patient is located in the center of a sound field created by multi-ple speakers 22 which accurately reproduce both pre-recorded environmental background sounds and pre-recorded or live "target-stimuli" such as speech.  Thus surrounded by a simulation of real-world listening situations, the patient initially selects a hearing aid shell assembly 12 which comfortably fits in the patient's ear.  A test module 200 which is connected to the patient's console 45 is then employed which snaps into the hearing aid shell assembly 12 and provides decision tree choices (Fig. 10) of electronic components (Fig. 6) and concomitant sound qualities which the patient chooses by listening to various combinations of components and sound conditions.  The patient chooses those components which give the most acceptable amplification and performance characteristics, which best address the patient's hearing loss.  Similarly, tinnitus conditions can be addressed as well.          After the patient has completed the test procedure and selected those components which best address the patient's hearing condition, electronic components 60, 112, 210, 212, 220, B1, C1-C4, R1-R3 with the same specifi-cations as those used during testing are snapped into the earshell assembly 12 used during the test so that the patient can leave with the hearing aid that he or she has selected.

Abstract: ABSTRACT OF THE DISCLOSURE        A modularly structured ISDN communication system has a system processor that is administered by a multi-tasking real-time operating system.  Since this operating system can only assign system-internal function programs to the system process (on-line system), a software application module have a time-sharing operating system is provided, so that the same processor can be administered by both operating systems.  In order to effect this, one task of the real-time operating system is fashioned as a sluice sub-system SUB in which an allocation switch from the addressing tables of the real-time operating system onto those of the time-sharing operating system occurs.           An interrupt transition routine that leads back into the sluice sub-system SUB in which the allocation switch is in turn cancelled is present in the time-sharing operating system for a processing of interrupt requests.  Messages can be forwarded from one operating system to the other by use of an intercommunication data segment, so that data from the administration of the one operating system can be transferred into that of the other operating system in a simple manner.
