Method and apparatus for authenicated on-site testing, inspection, servicing and control of life-safety equipment and reporting of same using a remote accessory

A method, apparatus, remote accessory and authentication server are provided for facilitating operations such as an authenticated test of life safety equipment having components including a control panel and sensors. The life safety equipment requires testing according to a fire code. An access procedure is conducted to identify equipment and testing requirements and to establish a communication session between the equipment and an authentication server during an authenticated test. Another access procedure is conducted to provide access for a remote device for facilitating the authenticated test and to establish a communication session between the remote device and an alarm system or authentication server, or the like. Information associated with an impending activation of one of the sensors is received from the remote device and information associated with the sensor, when activated, is reported if detected by the alarm system, to the authentication server and the reported activation information is forwarded to the remote device. Authentication information associated with the activated sensor whether or not detected is received from the remote device and an authenticated report is forwarded to the remote device when all of the alarm condition sensors are tested according to test procedures.

Multimedia scenario editor calculating estimated size and cost

A scenario editing system comprises a drawing input module drawing graphic media objects or inputting existing media objects; a scene management module storing and managing said media objects; a surrogate media management module storing said media objects for use as surrogate media objects temporarily representing actual moving picture objects, voice objects, or image objects to be created later; a surrogate media list module displaying said surrogate media objects in a list of thumbnails; a media attribute input module allowing a user to enter a media-dependent attribute of an actual media object to be created, while said surrogate media list module displays the list; a calculation module calculating sizes of actual media data and adding up the media data sizes to estimate a total size of an overall application, based on said media-dependent attribute; and a calculation result display module displaying the result of said calculation. The media attribute input module allows a user to enter the name of a person in charge and scheduled development time as an attribute, wherein the calculation module adds up actual media creation costs for calculation of an estimate of the cost of each media type and an overall application, and wherein the calculation result display module displays cost information for each media type and for the overall application.

Hydraulic control system for a continuously variable transmission

InactiveUS20010023217A1Less frictional lossIncrease line pressureGearingRoad transportControl systemRotation velocity
A transmission mechanism of the continuously variable transmission comprises a set of primary and secondary pulleys between which a belt is provided. The CVT control unit is operable to supply line pressure directly to a secondary pulley and also to a primary pulley via a shift control valve associated with a step motor in such a manner as to control a transmission ratio. The CVT control unit calculates a standard step position of the step motor corresponding to the target transmission ratio and provides a command signal representative of a difference between the standard step position and the current position of the step motor. The shift control valve actuated by the step motor controls the pressure to be supplied to the primary pulley. The actual transmission ratio obtained on the basis of the rotation speeds of the pulleys is compared with the target transmission ratio. If the shift is not accomplished, the CVT control unit commands additional step number. Unless the shift to the HI side is accomplished at the time when the additional step number reaches the threshold value, the line pressure is increased so as to achieve the shift. Thus, the transmission normally operates with a low line pressure sufficiently to reduce a frictional loss at the contact areas of the belt and the pulleys, thereby resulting in an enhanced fuel economy.

Semiconductor wafer grinding force on-line measurement device and force-controlling grinding method

The invention belongs to the ultraprecision machining field of the hard and brittle semiconductor crystalline materials and relates to a grinding force on-line measurement device used in the grinding process of the semiconductor wafer and a force-controlling grinding method. The invention discloses a semiconductor wafer grinding force on-line measurement device which is used as the feedback element of a grinding force adaptive control system. The grinding force measurement device adopts the piezoelectric measuring principle and contains a sensor part and a data processing unit, wherein the sensor part is used for the on-line measurement of the radial force Fr, the tangential force Ft and the axial force Fz; and the data processing unit is used to collect and analyze the grinding force data and perform feedback control to the feed speed and feed amount of the grinding wheel, thus the aim of on-line measurement can be achieved. The invention has the following advantages: the grinding force on-line measurement device has simple structure, and the modifications to the original equipment are less; the grinding force on-line measurement links are fewer, the response speed is fast, and the precision is high; and the grinding efficiency of the semiconductor wafer can be increased and the thickness of the damaged layer is reduced.
