Title: Method and apparatus for calculating arterial oxygen saturation based on plethysmographs including transients
IPC: A61B5/00
Filed: 1989-03-29
Abstract: A method and apparatus for improving the calculation of oxygen saturation by non-invasive pulse oximeters during transient conditions. Transient conditions introduce artifactual errors into the detected optical signal because of changes in transmittance of the light with localized blood volume changes and as the average background oxygen saturation level of the patient's blood changes. The invention relates to correcting the detected optical pulses by selective frequency filtering and compensating the detected optical signal using the filtered signal to provide accurate estimates of oxygen saturation during transient conditions.

Title: Method for realizing a service-specific command procedure in a calculator-controlled communication system, especially a key telephone system, with the posibility of breaking-in
IPC: H04M9/00
Filed: 1989-07-25
Abstract: A subscriber found to be busy can be informed about an urgent connection request concerning him by means of a particular information (call waiting). Normally, he is connected to the requesting subscriber station after termination of his call connection and return to the idle state. According to the invention, a particular signalling information can be transmitted with the handset still off the hook or with maintenance of a handling, corresponding to this off-hook condition, of the controller (ZSt) monitoring the connection phases. By this means, the connection is released if the connection request is maintained by the requesting subscriber but the sequences normally connected with the return to the idle state are supressed. The establishment of a connection with the requesting subscriber intended for such a case is prevented and the dialling information for the immediate setting-up of an intended subsequent connection can be transmitted. <IMAGE>

Title: Analog to digital converter
IPC: H03M1/34
Filed: 1989-08-09
Abstract: One of analog input voltages applied to a plurality 
of analog input terminals (CH1, CH2) is selected by 
means of analog switches (P₁, N₁, P₂, N₂) connected to 
the respective analog input terminals (CH1, CH2) and 
supplied to a common terminal (A). In this case, each 
of the analog switches (P₁, N₁, P₂, N₂) permits selective 
supply of the potential of a corresponding one of 
the plurality of analog input terminals (CH1, CH2) in 
response to a control signal supplied from a controller 
(12). The common terminal (A) is connected to the positive 
input terminal of a comparator (1). The comparator 
(1) compares the voltage with a digital output value 
from the controller (12) which is converted into an 
analog voltage by means of a D/A converter (2). 
Further, the controller (12) generates a preset control 
signal ( PR ) in an inhibition period during which supply 
of a voltage from the plurality of analog input terminals 
(CH1, CH2) to the common terminal (A) is inhibited. 
An initial potential setting circuit (11) sets the 
potential of the common terminal (A) to a voltage level 
equal to substantially one-half the maximum voltage 
level of the analog input voltages applied to the plurality 
of analog input terminals (CH1, CH2).

Abstract: A radio telephone set comprises switch 
circuitry (51), a telephone circuit (71) and a battery (81) for 
portable operation, which battery may be a built-in 
battery. When the radio telephone set is not mounted 
on a vehicle, the switch circuitry is not connected 
to a battery of the vehicle and feeds power from the 
built-in battery to the telephone circuit. Thus, the 
radio telephone set can be used as a portable set. 
When the radio telephone set is mounted on the 
vehicle, the switch circuitry is connected to the 
vehicle battery and this connection causes the 
automatic switching of the power supply to the 
telephone circuit from the built-in battery to the 
vehicle battery. Thus, the radio telephone set can 
be used as a vehicle-mounted, or onboard, set.

Title: Position servo system and its method of operation
IPC: G11B7/09
Filed: 1990-03-05
Abstract: A position servo system has a position loop and a velocity loop. The position loop controls the 
stop-lock condition and provides for movement control within a range about the stop-lock position. The velocity circuit is 
employed for movements outside of the range of the position servo circuit. When the velocity servo's loop is being used, a 
compare circuit compares the servo drive signal from the velocity circuit with a signal generated by the position servo loop 
which is tracking the velocity servo loop. When the compare means finds that the servo drive signals have equal amplitudes, 
then the velocity servo loop is disconnected from an actuator with the position servo loop then connected to the activation 
for completing the movement to a desired or target stop-lock position. The above-indicated servo system controls a topping or 
fine actuator (46) carried on a carriage (34) moved by a coarse actuator (36). The fine and coarse actuators move along the 
same axis and transverse to movement of any work element, such as a record storage disk (30). The coarse actuator is 
continuously slaved to the positioning of the topping or fine actuator (46). A relative position sensor (37) disposed 
intermediate the fine (46) and coarse actuators (36) supplies a position error signal for enabling the coarse actuator (36) to 
continuously follow the fine actuator (46). Feed forward signals are supplied from the fine actuator (46) to the coarse 
actuator (36). A preferred embodiment is shown using an optical disk environment.
