摘要:
A system for actively displaying moving images on a container sidewall (105), which comprises a display unit (120), control unit, and a power unit. The system is secured within the interior of the container (100), while the display screen is flush with the container sidewall (105) so that the outer shape and other characteristics of the container (100) resemble a regular container. The control system may be used to allow automatic control or manual control of the underlying system.
摘要:
A security apparatus and a method for determining the distance between a computer (72) and a token (70) carried by a user (52) for allowing the user (52) to access the computer (72). The computer (72) is connected to a first transceiver (16) having at least one antenna for emitting and detecting a radio frequency (RF) signal, and to a microphone (76) for detecting an audio signal (24). The computer (72) is also connected to a counter (26) for measuring a time interval (28) between a transmitted RF signal (20) and audio signal (24) from the token (70). The token (70) is connected to a second transceiver (30) having at least one antenna for emitting and detecting an RF signal (20) and a loudspeaker (74) for emitting an audio signal (24). The method is characterized by comparing the measured time interval (28) to a predetermined time range (38) and enabling the computer (72) in response to the time interval (28) being within the predetermined time range (38) such that the user (52) may have access to the enabled computer (72) and disabling the computer (72) in response to the time interval (28) being outside the predetermined time range (38).
摘要:
A tool condition monitoring system (10) monitors the power consumption of a tool during performance of a cyclical task. The system monitors (16) a plurality of characteristics of the power consumption and diagnoses the condition of the tool based upon the plurality of characteristics. A rule base of the plurality of characteristics is generated in a learning mode by monitoring a tool of known condition for a plurality of cycles. In monitor mode, the system monitors the power consumption of a tool and diagnoses the condition of the tool by indexing the rule based upon the plurality of characteristics monitored. In addition, a method is disclosed wherein the band may be modified for accommodating tool wear, such that a tool, although dull, may be utilized and monitored.
摘要:
@ Existing auditory warning systems are in general too loud and it is often difficult to distinguish between a number of different warnings. Further under different conditions warnings may change character due to masking by varying noise. A warning system is disclosed which is based on a microprocessor 35 and waveforms for each warning sound stored in a ROM 32. The waveforms are read out to DACs 42 and 43 and used to drive a loudspeaker 45 by way of programmable attenuators 38 and 39. Each waveform is devised to have at least four quasi-harmonically related frequency components at a power level in the range 15 to 30 dB above threshold. In this way the sounds are distinctive and do not change character with varying noise levels below threshold.

Système (1) et procédé d'aide à la gestion de listes de commandes sur un aéronef, le sytème comportant une unité d'identification (2) pour identifier au moins un élément d'actionnement à actionner afin de mettre en oeuvre une commande courante d'une liste de commandes, une unité de signalisation (3) pour mettre en évidence visuellement l'élément d'actionnement identifié, une unité de détection (4) pour détecter une position d'une main d'un pilote, une unité de vérification (5) pour vérifier si la position détectée de la main du pilote est cohérente avec la position de l'élément d'actionnement identifié et mis en évidence en vue de son actionnement, une unité d'alerte (6) pour alerter le pilote d'un risque d'actionnement erroné, en cas d'absence de cohérence entre la position détectée de la main du pilote et la position de l'élément d'actionnement, et une unité de récupération (15) pour identifier, en cas d'actionnement erroné, au moins un élément d'actionnement permettant de remédier à la situation générée par l'actionnement erroné.
摘要:
An electric field detector includes field detection circuitry configured to detect voltage in an electric field in an environment and configured to determine if the voltage meets or exceeds a voltage threshold. A warning module operably connected with the field detection circuitry is configured to provide a warning to operators in the environment. A communication module operably connected with the field detection circuitry communicates a warning notification to another electric field detector.
