20150025399 | AUTOMATIC BLOOD PRESSURE MEASUREMENT DEVICE - An automatic blood pressure measuring apparatus includes: a compression band wrapped around a compressed site of a living body, the automatic blood pressure measuring apparatus sequentially extracting a pulse wave that is pressure oscillation in the compression band in a process of changing a compression pressure value of the compression band to determine a blood pressure value of the living body based on a change in the pulse wave, the compression band having a plurality of expansion bags having independent air chambers aligned in a width direction to respectively compress the compressed site of the living body, the automatic blood pressure measuring apparatus sequentially calculating an amplitude ratio of an amplitude value of a pulse wave from a predetermined expansion bag positioned on a downstream side of an upstream expansion bag positioned on an upstream side of an artery in the compressed site out of the expansion bags. | 01-22-2015 |
20140332290 | WEIGHING APPARATUS - A weighing apparatus is provided that quantifies an impact load based on an electrical output from a mass sensor to prevent damage to the mass sensor by disclosing the degree of impact to a user. The weighing apparatus includes a weighing unit on which an object is placed and a mass sensor that receives the mass×acceleration of gravity of the object as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus. The apparatus quantifies and records the amount of the displacement, and determines acceleration by a numerical calculation from the displacement data. The obtained acceleration quantifies the amount of impact applied on the weighing apparatus by the object, and may be used to warn the user when the weighing apparatus is in danger of damage. | 11-13-2014 |
20140297229 | DATA LOGGER FOR MEASUREMENT DEVICE - For easy centralized management of measurement data and installation environmental data and user's real-time recognition through a certain type of peripheral equipment of how the installation environment affects the measured values at the site of measurement, a data logger for a measurement device includes in its structure any of the sensors for temperature, humidity, air pressure, and acceleration as an environmental sensor that detects a physical quality of an environment where the measurement device is installed, a data recording unit that records installation environmental data detected by the environmental sensor and measurement data detected by the measurement device on the basis of time, and a data processing unit that displays the installation environmental data and measurement data in whole or selectively, as numerical values or graphs of changes over time, with the time axes aligned, and includes one or more external equipment terminal connectors that exchange signals with external equipment. | 10-02-2014 |
20140291043 | MEASUREMENT DEVICE - To prevent measurement errors caused by impact including an impact load transmitted at high speed or static electricity and prevent destruction of a sensor unit due to the above-mentioned impact load. Through-holes ( | 10-02-2014 |
20130306382 | WEIGHING APPARATUS - To provide a weighing apparatus by which it is possible for a user himself/herself to determine poor performance of the apparatus is a factor attributable to an installation environment, and the weighing accuracy is improved. Respective temporal fluctuations in weighed data detected from a load measuring mechanism | 11-21-2013 |
20130068542 | WEIGHING DEVICE HAVING A WEIGHING CHAMBER - A weighing device is provided that suppresses air convection currents generated in a weighing chamber in the opening/closing of a door of the chamber with a relatively simple configuration. A weighing space is partitioned into two spaces with a partition plate to form a lower small-capacity weighing chamber, which enables to settle down the convection in a short time if convection is generated in the chamber. Suspended walls adjacent to the doors are attached to the partition plate edge sides along the door opening/closing directions. Even when a door is opened, warm air stagnant in the upper space in the chamber is restricted or blocked to flow out to the outside by the suspended walls, which generates no convection or slight convection, which settles down in a short time, without adverse effect on a weighing operation. The upper space may be utilized for another purpose such as a neutralization chamber. | 03-21-2013 |
20120325566 | WEIGHING DEVICE WITH WINDPROOF STRUCTURE - The effect of air flow on a weighing dish is minimized by the following relatively simple arrangement. A mounting member ( | 12-27-2012 |
20120060596 | CHASSIS DYNAMOMETER - A chassis dynamometer for a vehicle has a base seat, a fixed shaft having one end thereof attached to the base seat, a rotary proximal portion rotatably supported to the fixed shaft, a roller connected to the rotary proximal portion, for loading a wheel of a vehicle, and a motor connected to the roller so that power can be transmitted therebetween. The roller has a single flange portion connected to the rotary proximal portion and extending obliquely to the axis, and an outer peripheral portion extending both axial directions from an outer periphery of the flange portion and disposed outward in the radial direction of the motor. | 03-15-2012 |
20100179742 | ENGINE CHARACTERISTIC ESTIMATION METHOD, AND COMPUTER READABLE MEDIUM - A method for estimating steady state values of engine operating characteristics is provided so that engine control can later be based on the estimated values. An amount of change in a specific engine characteristic (for which the steady state values are to be estimated) is set as a product of an unknown value and a dimensionless known value for predetermined times from when a specific engine control parameter is changed. A value of the specific engine characteristic at a given time is calculated as a sum of the products at the given time, with the products respectively corresponding to plural prior changes in the specific engine control parameter. Unknown values are calculated multiple times based on values of the specific engine characteristic measured in a conformance test, and the steady state values of the specific engine characteristic are estimated. | 07-15-2010 |
20090242280 | LOAD MEASURING MECHANISM FOR ELECTRONIC BALANCE, AND METHOD FOR ASSEMBLING THE SAME MECHANISM - An integral type second lever constituting member (A) is mounted on a constitution, in which a first lever member ( | 10-01-2009 |
