Patent EP-0202408-A3 (EP)
Title: A paging system, particularly for hotels
IPC: H04M11/02
Filed: 1986-03-12
Abstract: In a paging system for hotel guests, use is made of the pigeonhouse-like structure (18), wherein keyholders (20) are deposited by the guests, for indicating to the telephone switchboard operator of the hotel whether a guest is available for an incoming call, rather than referring it to the reception desk (12). Each compartment of the structure is provided with keyholder presence/absence indicating means (24,26) which are coupled to the telephone switchboard (10). The absence of a keyholder will indicate that the guest is in his room, or that he is elsewhere on the hotel premises. In the latter case, the operator will transmit a paging signal to a receiver installed in the respective keyholder. Special requirements of guests may be accommodated through the use of dummy-keyholders, replacing the normal keyholders within the structure.

Title: Hand-held self-contained electronic tonometer
IPC: H03F1/22
Filed: 1986-09-25
Abstract: Disclosed is a battery powered, hand-held self-contained electronic tonometer with a digital readout for displaying pressure in millimeters of mercury. The tonometer includes a transducer which is a solid state pressure sensitive element and which produces a voltage proportional to intraocular pressure. An electrical waveform is produced by gently bringing the transducer in contact with the cornea. The waveform is converted to a digital signal and processed by a single chip microprocessor. The baseline of a reference signal is nulled by equalizing the charges on two capacitors on the inputs of two differential amplifiers. Equalizing the differential inputs of the two amplifier stages results in a gain of zero and removes any carrier signal. Microprocessor software detects the baseline condition established by equalizing the differential inputs. The microprocessor then looks for a series of valid measurements and calculates the average intraocular pressure along with an estimate of reliability. This average value and the reliability indicator are displayed on a liquid crystal display.

IPC: B01D24/46
Filed: 1986-06-25
Abstract: An improved method of cleansing a filter bed is herein 
provided utilizing a backwash pump (12) having an inlet line 
(14) and an outlet line (16). The improved method and system 
includes two cycle operations. Initially, the filter bed is back­
wash to remove contaminants from the filter bed with the 
backwash pump (12) drawing liquid from an effluent channel 
(26). A portion of the liquid passing on backwash pump outlet 
line (26) is passed through a bypass adjustment valve (34) for 
egress on an outlet line (38) for recirculation to the effluent 
channel (26). The second stage of the cleansing operation is 
through a purging cycle where the filter bed is purged subse­
quent to the backwashing operation for removal of further con­
taminants from the filter bed. In the purging cycle, a closed loop 
system is formed between the backwash pump (12) and the 
backwash shoe (28) with a portion of liquid being diverted 
through a purge adjustment valve member (44) for egress on 
an outlet line (46) external to the system or to a separate filter 
member.

appropriate testing process flow information in response to 
inquiries displayed on the PC screens. The test implementing 
program thereby created is effective to subsequently present on 
the PC display, testing procedures and probe placements to an

Filed: 1987-04-29
Abstract: The data display-controlling device of the present inven­
tion includes a control key used for reducing the speed at 
which data is displayed on a display unit. If the control key is 
depressed, this condition is detected by a central processing 
unit (CPU). Upon detection of the depression of the control 
key, the CPU reads current time from a timer, and determines 
whether a predetermined time has passed from the depres­
sion of the control key. If the predetermined time has not yet 
passed, the CPU executes the operating system program, and 
if the predetermined time has passed, data to be presented is 
supplied to the display unit.

dem Verteiler, der die Funktion der Druckausgleichung des 
Arbeitsmediums in dem Ventilgehäusemittelteil mit dem 
Druck in der Zuleitung, wie auch die Mediumüberströmung

Title: Anti-lock control method for vehicle
IPC: B60T8/32
Filed: 1988-01-26
Abstract: In a vehicular anti-lock control method including the steps of comparing a wheel speed with a reference value which is based on a vehicle speed estimated from the wheel speed, judging the locking tendency of a wheel from the result of such comparison and reducing a brake pressure to be applied to the wheel which is on the way to locking, a first vehicle speed is estimated based on the speed of a wheel including a driving wheel and a second vehicle speed is estimated based on the speed of a follower wheel, the driving wheel being judged to be in a racing state when the first vehicle speed is larger than the second vehicle speed above a predetermined value. When the driving wheel is racing, the first vehicle speed is held constant and as far as such racing is present the constant vehicle speed is used to determine the reference value for comparison with the wheel speed.
