摘要:
A microsensor for detecting corrosive media acting on a bulk metallic material when mounted in situ adjacent a location in the bulk metallic material. The microsensor includes a plurality of corrosion sensors (4A, 4B, 4C) exposed to the corrosive media, each having corrosive tracks formed from a patterned conductive thin film. The different sensors have different characteristics, such as track width, track thickness, track composition, surface type, sensor type, etc. so as to provide the sensors with different sensitivities, corrosion indications and lifetime characteristics. Such microsensor arrangements provide improved corrosion detection at high degrees of miniaturisation.

A microsensor for detecting corrosive media acting on a bulk metallic material when mounted in situ adjacent a location in the bulk metallic material. The microsensor includes a plurality of corrosive tracks (16; 132; 216B) exposed to the corrosive media, each said corrosive track being formed as a patterned conductive thin film track. The tracks follow serpentine paths which include a plurality of bends, at least two of which are of opposite curvature, to provide a high degree of miniaturisation coupled with accurate and reliable corrosion sensing characteristics. The corrosive tracks may be formed from an alloy material, such as an aluminium alloy, to mimic the corrosive characteristics of a bulk metallic alloy and to provide improved corrosion detection for components made from such materials at high degrees of miniaturisation.

A system for driving a torsion based on frequency, amplitude and offset control signals includes a pulse width modulator subsystem configured to generate output pulses having controlled pulse durations alternately to each of two channels, the output pulses encoding the frequency, amplitude and offset control signals. A driver circuit is configured for driving the torsion oscillator with a voltage of one polarity during a pulse output to the one of the channels, and a voltage of opposite polarity during a pulse output to the other of the channels.

A barrier device forms an inflatable barrier that restricts an object from passing through an opening at the periphery of a support structure, such that a substantial portion of the opening is blocked. The support structure may include furniture. A bladder is inflated with a gas to conform to the size of the opening. The bladder has a first region and a second region that fold over each other to conform to the size of the opening for providing a more substantial barrier. A first end and a second end have an inlet for enabling passage of the gas to and from an interior region of the bladder. In this manner, the size of the bladder can be adjusted. A handle on either end facilities mobility of the device.

A circuit includes a switching device for controlling a power signal to be applied to a heating device. A control circuit is configured for comparing a temperature signal, indicative of the temperature of the heating device, to a temperature setpoint to generate a gate pulse signal that controls the duration of the power signal to be applied to the heating device. The control circuit is further configured for comparing the duration of the power signal to be applied to the heating device to a minimum pulse duration and, if the duration of the power signal to be applied to the heating device is at least equal to the minimum pulse duration, providing the gate pulse signal to the switching device.

A method and apparatus for accessing a color palette in a color graphics system synchronously and asynchronously. Address and data registers coupled to the color palette are operated synchronously in a pipeline fashion using clock pulses having a pixel scanning rate when the palette is used for refreshing a color monitor. The address and data registers are operated asynchronously, i.e. rendered transparent to addresses and data, respectively, when the palette is updated by a CPU.

The Rotating Car Wheel Display allows perspective customers interested in purchasing a car rim or wheel to see the rim or wheel in motion as it would be on the car itself. It operates in a clockwise and counterclockwise motion for spinning wheels and traditional rims and wheels. It is a portable device that can be displayed easily and inexpensively by any wheel and tire shop for more curb appeal.

Monitoring an electronic check processing status of an image cash letter (“ICL”) and items in the ICL includes processing each ICL item by performing at least one electronic check processing event in connection with the item. For each electronic check processing event and for each item, a record comprising information related to a status of the electronic check processing event is created. Each record is associated with the corresponding item and the ICL. A status of each item can be determined based on the information stored in the records corresponding to that item. A status of the ICL can be determined based on the status of the items from the ICL.

Systems and methods for providing encryption and decryption of data transmitted on a computer implemented network, preferably user authentication identifier data, such as a password, at the point of entry into the user's computer. The systems and methods enable an end user to mentally select a marker from one of the randomly arranged elements on a first portion of a graphical image. A second portion of the graphical image includes an arrangement of possible elements of any individual authentication identifier sequence, and is positioned adjacent to the first portion. The systems and methods prompt a user to enter each element of the identifier by moving the selected marker and the first portion as necessary to substantially align the selected marker with a chosen element of the authentication identifier appearing on the outer portion. According to one embodiment, the image portions are concentric wheels. According to another embodiment, the image portions are arranged in adjacent rows.
摘要:
Balancing image cash letters (“ICLs”) and ICL items during electronic check processing includes determining whether each item has been presented to a receiving institution for payment. A tracking module can track an incoming ICL/item's processing status using records comprising information regarding the ICL/item's status for electronic check processing events. The tracking module can present the ICL/item's processing status in one or more reports. The tracking module can balance an ICL by comparing an incoming ICL value amount with an outgoing ICL value amount. The incoming ICL value amount comprises the total value of the items in the incoming ICL. The outgoing ICL value amount comprises the total value of the items in the incoming ICL that have been presented to a receiving institution via one or more outgoing ICLs. If the amounts match, then the incoming ICL is balanced. If not, then the ICL is not balanced.
