Abstract: Systems and methods utilizing a two-way mirror display for patient self-positioning for dental x-ray image acquisition. The system includes a camera configured to capture an image of a patient, a display, a two-way mirror positioned between a patient location and the display, and an electronic processor. The electronic processor is configured to select, based upon a user input, an operating mode for the display; and based upon the selected operating mode, displaying at least one image on the display. The method includes receiving image data from a camera, identifying at least one facial feature of the patient in the image data, determining if a face of the patient is aligned with at least one anatomical plane based upon the at least one facial feature, and displaying at least one movement guide on a display based upon the determined alignment of the face of the patient.

Abstract: An X-ray dental imaging system for medical imaging includes a column, a housing coupled to the column, and a lower shelf movably coupled to at least one of the column or the housing.

Abstract: A patient positioning apparatus for an X-ray dental imaging system includes a head rest and a chair separate from and spaced from the head rest. The chair has a seat portion and a back rest coupled to the seat portion. The chair further includes a locking system that locks a position of the back rest relative to the seat portion.

Abstract: A tip assembly for an intraoral scanner includes a tip support body having a first end, a second, opposite end, and an outer surface located between the first end and the second end. The outer surface defines at least one protrusion or recess. The tip assembly further includes a disposable, flexible mirror strip having a first end, a second, opposite end, and a mirror fixed to the second end. The flexible mirror strip defines at least one protrusion or recess that engages the at least one protrusion or recess of the tip support body to releasably couple the flexible mirror strip to the tip support body. The tip assembly further includes a tip sleeve having a first end and a second, opposite end. The tip sleeve is sized and shaped to slide over at least a portion of both the tip support body and the flexible mirror strip.

Abstract: The object of the invention is a method for installing and servicing an apparatus module recovering the kinetic energy of water; and the apparatus module itself. The apparatus module with wave energy recovering units is descended into the sea bottom and is kept steady at the sea bottom by the help of its own mass and the mass of the water filled into a plurality of soft and hard compartments and valve compartments in the body of the apparatus module. Correspondingly the apparatus module is lifted into the surface of the water and made floating by the help of air that is blown to the plurality of soft and hard compartments and the valve compartments in order to replace the water.

Abstract: The object of the invention is a method for installing and servicing an apparatus module (1) recovering the kinetic energy of water; and the apparatus module (1) itself. The apparatus module (1) with wave energy recovering units (3) is descended into the sea bottom (12) and is kept steady at the sea bottom (12) by the help of its own mass and the mass of the water filled into the compartments (2a and 2c) in the body (2) of the apparatus module (1). Correspondingly the apparatus module (1) is lifted into the surface of the water and made floating by the help of air that is blown to the compartments (2a) and (2c) in order to replace the water.

Abstract: A method of tuning a station is disclosed, wherein a first pilot signal is applied on a circuit of the station and the resulting output power of the signal circuit is subsequently detected. A second pilot signal is then applied to the circuit and the resulting output power of the circuit is detected. The offset of the circuit is then tuned based on information of the resulting output power detected for the first and second signals. A station that is adapted to implement the method may be tuned by the manufacturer thereof or later after having already been taken into use. The tuning may occur automatically as response to a predefined event.

Abstract: The invention is related to a method for improving handover in reception and transmission in a digital cellular mobile communication system including base stations and mobile stations, in which mobile station receives from a base station a handover command in the middle of speech reception or transmission on a first reception or transmission channel, whereby in the handover, the reception/transmission is changed to a second reception or transmission channel. Particularly the invention is related to mobile communication systems based on time division multiple access, in which transmission and reception occur in bursts in separate time slots. In the method according to the invention, speech is sampled, or, in transmission, it is A/D converted (32), and in reception, it is D/A converted (22) during the handover and stored in memory, e.g.

Abstract: The strength of the signal or carrier in one or more transfer channels near the receiving channel of a radio device operating in a radio telephone system is measured, for example, with a MAHO measurement. The measurement result is used to calculate the disturbance caused by the transfer channel to the receiving channel, and, based on the acquired result, the frequency response of a filter included by the receiver is adjusted, for example, by changing the width or slope of the passband.

Abstract: A power control loop for a radio frequency transmitter includes a power control amplifier, an output and a detector that is coupled to the output for providing an output power signal indicative of output power from the power control loop. A controller generates at least first and second reference signals. A differential amplifier provides a control output that is indicative of a difference between the output power signal and a reference signal. A dual rate filter couples the control output to the power control amplifier so as to vary its gain. The dual rate filter exhibits a fast-reacting filter mode when the controller changes the reference signals to the differential amplifier and a slow-reacting filter mode when the controller applies the first reference signal to the differential amplifier. The fast filter mode enables rapid feedback of the control output to the power control amplifier.
