Filed:

Nov 3, 2000

Appl. No.:

09/706282

Inventors:

Hiro Moriyasu - Portland OR 97221

International Classification:

G01C 906

US Classification:

3336615, 3336611, 3336618, 3336622

Abstract:

A digital inclinometer detects an inclination angle by sensing varying conductive current of various electrodes. When the inclinometer is rotated through an inclination angle, various segments of the sensing electrodes become immersed in a conductive fluid causing varying conductive currents to these sensing electrodes. A driving signal is applied to driving of electrode and the sensing side of electrodes is kept at a constant voltage by connecting them to an analog ground or to current sensing amplifier which maintains virtual ground during measurement to achieve an equipotential at both sides of the sensor plates. An Analog to Digital converter, microprocessor, and LCD display achieves a digital readout. Novel methods allow 360-degree precise measurements, while overcoming traditional limitations and errors due to fringe effects, non-linearity, and various environmental changes.

US Classification:

310 81, 310 15, 310 36

Abstract:

An ultra-low profile vibrating transducer, particularly suited for floor mat and ultra thin vibrating pad and multimedia tactical feedback applications, using an “I” core coil in the center and permanent magnets positioned at both ends of the “I” core to create balanced push-pull vibrating actions. Mounting methods to effectively transfer energy to the users while withstanding user's body weight. “I” core coil may be driven by AC power, pulsed and/or DC power or audio power. Elastomeric supports are configured to provide rotational leverage action to further enhance the vibrating effectiveness.

International Classification:

A61H023/02

US Classification:

601/057000, 601/059000, 601/070000

Abstract:

Present invention describes a novel vibrator motor apparatus method of effectively transferring vibrating energy to the user, having supporting structure to prevent vibrating motors from collapsing due to the body weight compressing down against floor. Proposed methods and apparatus overcome limitations of effectively using vibrating motors for low profile floor mat applications.

G06F 500
G06F 1300

US Classification:

364900

Abstract:

A general-purpose oscilloscope system is disclosed wherein waveforms acquired by the vertical and horizontal preamplifier channels can be displayed immediately, or they can be digitized and stored in a memory from where they can be recalled, reconstituted in their analog form and displayed at a later time. The processing system permits simultaneous display of instantaneous and processed waveforms, and includes facilities for processing associated z-axis signals and readout data as well. Access to peripheral equipment, such as a computer or the like, permits the digitized waveforms to be mathematically manipulated and returned to the memory in the processing system for ultimate display. The oscilloscope system can be assembled in a modular manner, whereby the processing unit becomes an integral part of the instrument, or the system can be assembled as a general-purpose oscilloscope without the processing unit, allowing a user to add the processing capability to his system at a later time.

Appl. No.:

8/686732

Inventors:

Hiro Moriyasu - Portland OR

International Classification:

A61H 100

US Classification:

601 30

Abstract:

A low profile vibrating floor mat includes a magnetic gap elastomer placed between vibrating magnetic laminates. The elastomer controls the magnetic gap and prevents the magnetic gap from physically collapsing due to the body weight. Upper and lower protective materials insulate the vibrating magnetic laminates from the environment while effectively transfering vibrating energy to the surface of the floor mat. The floor mat is able to withstand body weight.

International Classification:

H03M 100
G01R 2316

US Classification:

341123

Abstract:

A signal acquisition system using an ultra-wide time range digitizer with variable time interval data sampling and data storage includes signal conditioning and sampling stages, a digitizing stage for generating digital representations of a signal, and a memory for storing the digital representations. Timing circuitry controls sampling and digitizing which may be varied so as to acquire signals on linear, logarithmic, or other time bases. Signal compression may be obtained by digitizing information only when a desired change rate is observed. A display allows acquired signals to be displayed in linear, logarithmic or other manner.

International Classification:

G06G 762

US Classification:

364578

Abstract:

An electronic circuit parameter extraction system is provided with a pulse signal forcing generator, an interface to a device under test (DUT), a signal digitizer, a timebase to control the digitizing interval, a data processor to extract DUT essential root parameters, a circuit and/or system simulator to generate signals from the extracted parameters, and a display system to view acquired and/or simulated signals, and is able to compare simulated signals with previously acquired signals. The circuit parameter extraction system further allows extraction of realistic behavioral model parameters which may be used as a component library model within a computer aided engineering (CAE) simulator, allowing improved convergence between the results obtained with the CAE simulator and the physical circuit system response being modeled.
