Title: Calibration of magnetic and optical sensors in a virtual reality or augmented reality display system
Inventor: WOODS MICHAEL
IPC: G06F3/01
Filed: 2017-09-25
Abstract: A system for calibrating alignment of magnetic and optical sensors in a virtual reality (VR) or augmented reality (AR) device. The system can include a controller, a waveform generator, and an electrical driver. The waveform generator can produce calibration waveforms under control of the controller. The system can also include conductive loops which are energized with electrical currents corresponding to the calibration waveforms. The controller can cause the waveform generator to generate a first calibration waveform to calibrate a first type of magnetic sensor in the display device, and to generate a second calibration waveform to calibrate a second type of magnetic sensor in the display device. The system may also include one or more optical fiducial markers in a known spatial relationship with respect to the conductive loops. The optical fiducial markers can be used to calibrate the alignment direction of one or more optical sensors.

Filed: 1994-08-04
Abstract: FIELD: electronic devices. SUBSTANCE: single discriminator with constant threshold does not provide compensation of temporal stroll of output signal, while two discriminators with constant different threshold gates for each pulse provide possibility of precise time reference, but such requires double number of measuring channels and doubled number of subsequent calculations. Invention introduces discriminator having two thresholds which outputs pulse using two temporal measurements for each input pulse. Two circuits for compensation of time stroll of pulse have capacitor and resistor (or power supply), which are controlled by input comparators by means of switches S1 and S2. When comparators are triggered by input pulse, direct voltage power supplies are turned off and voltage at capacitors changes. Output comparator is triggered when voltage levels at its output become equal. Moment when output comparator is triggered does not depend on amplitude and leading edge of linear increased input signal if condition U/U= (C•R)/(C•R) is satisfied in case of RC compensation circuits or condition U/U= (C/I)/(C•I) if power supplies are used instead of resistors. In these equations, U,Uare thresholds of input discriminators, C,Rand C,Rvalues of capacitance and resistance in RC circuits, I,Iare currents of power supplies. EFFECT: increased functional capabilities. 1 dwg

IPC: H02M5/257
Filed: 1994-08-17
Abstract: FIELD: voltage regulation for lighting devices, heating appliance, and miscellaneous domestic and industrial pieces of equipment. SUBSTANCE: voltage regulator has thyristor 5 controlled by phase-adjusting circuit set up of capacitor 9, resistor 10, voltage divider 8, and first voltage regulator diode 7. Varying the value of resistor 10 changes voltage across load 2 connected through diode bridge 1 and thyristor 5 to supply mains buses 3 and 4. Light-emitting diodes are introduced to display voltage across load. Current flowing through parallel-connected series circuits set up of resistors 13.1 through 13.N, voltage regulator diodes 14.1 through 14.N, and light-emitting diodes 15.1 through 15.N depends on ON-state duration of thyristor 5. When thyristor 5 is cut off, this current is of maximum value and all light-emitting diodes 15.1 through 15.N are glowing. When thyristor is conducting for most part of AC voltage frequency period and load is placed at maximum voltage, all light-emitting diodes are dark. Voltage regulator may be found useful for lighting devices for controlling voltage across electric lamps and for visual locating light switch in entering non-eliminated dark room. EFFECT: enlarged functional capabilities.

Abstract: FIELD: manufacture of aircraft engines. SUBSTANCE: after vibratory burning mode has been attained, periodic fluctuations of pressure and gas velocity occur in afterburner. Acoustic vibrations of gas given rise to gas vibrations in perforations 5 and 6 of fairing 4 which act on gas vibrations of afterburner as resonance absorber (Helmholtz absorber). Since acoustic field inside fairing 4 is similar to field in quarter-wave-length resonator, pressure vibrations through perforation 5 of outlet section of fairing 4 occur at delay relative to gas pressure vibrations in combustion chamber at perforation 6. Perforation 6 is located at distance from end of fairing equal to 60 - 70 percent of its length which makes it possible to perform optimal adjustment of fairing 4 together with bushes 7 as Helmholtz resonator and to ensure efficiency dampening of acoustic vibrations in wide range of working modes of afterburner. Losses of vibratory energy are considerably reduced due to fitting blanks made of porous material, metal-base rubber for example. When acoustic vibrations develop in afterburner provided with longitudinal partitions, dissipation of energy takes place in holes 5 and in bushes. EFFECT: intensified dampening of pressure and gas velocity vibrations.

Title: Water treatment system combining ozone injection apparatus and monitoring apparatus
Inventor: CHANG STEVEN SHIH-YI
IPC: C02F9/00
Filed: 2002-11-14
Abstract: A water treatment system, having a filtering apparatus and a sterilizing apparatus that is able to generate ozone and has an ultraviolet lamp, includes a ozone gas injection apparatus and a monitoring apparatus. The ozone gas injection apparatus having a main water pipe that has a water inlet and a water outlet includes a venturi tube and a check valve. This ozone gas injection apparatus is used for absorbing ozone gas as the filtered water flow into the main pipe via the water inlet. The water then pass through the venturi tube to generate a relatively low pressure so as to absorb the ozone generated from the sterilizing apparatus and transmitted through an ozone transmission pipe. The check valve, which allows the ozone to flow through and then being absorbed into the main water pipe, can block the water from flowing out of the main water pipe into the ozone transmission pipe. The ozone-absorbed water flowing out of the main water pipe via the water outlet, after being squeezed and impacted, is mixed with ozone thoroughly and flows into the sterilizing apparatus. The monitoring apparatus includes a specially-designed flow meter for calculating the service life of the filtering material by measuring the flow rate and the accumulated water flow, and a pressure sensor for generating output signals in order to control the switch of the ultraviolet lamp.
