摘要:
A method of transmitting information to a mobile device includes providing a read head with a slot for swiping a magnetic stripe of a card, a power supply coupled to wake-up electronics and a microcontroller. The wake-up electronics are powered by a microphone bias of a mobile device.
摘要:
Fluorescence chromophores such as phenylene diamine derivatives can undergo oxidative coupling and polymerization to form optical, colorimetric and fluorogenic, multimers and polymers. The presence of carbonyl containing moieties such as aldehydes and ketones under favorable environmental conditions can initiate, catalyze, accelerate and modulate this reaction which in turn provides a mechanism for the detection and quantitation of such moieties. Selected phenylene diamine derivatives can be used for the detection and quantitation of aldehyde and ketones via measurement of the reaction and the associated spectroscopic transformation. In particular, the use of meta-phenylene diamine (mPDA) and related compounds for aldehyde detection and quantitation is described. The method provides a convenient means for monitoring aldehyde and ketone levels without use of separation steps. The method is applicable to kinetic and quasi-endpoint detection assay formats.

The present disclosure relates to durability enhancement techniques for a dry-clutch vehicle transmission. A cooling system that provides a direct convective cooling path to friction surfaces is disclosed. Also disclosed is a continuously variable clutch wear compensation assembly configured to adjust the position of clutch assembly components on-demand or as needed.
摘要:
A family of transmissions has four planetary gear sets, five controllable clutches and brake, and a passive one way brake. Selective engagement of the brakes and clutches in combinations of three produces eight forward speed ratios and one reverse speed ratio. The passive one way brake is engaged in the first forward speed ratio and overruns in the second through fifth forward speed ratios.

A sleeve bearing assembly and method of construction therefor includes a woven inner portion bonded to an injection molded elastic outer portion. The inner portion includes a first yarn of lubricious yarn material and a second yarn of material that is different than the first yarn. The first yarn substantially provides an inner bearing surface and the second yarn substantially provides an outer surface that is bonded to the outer portion. The first and second yarns are woven together so that the first yarn is woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface to substantially provide the bearing surface and the second yarn is woven in a direction different than the first yarn to substantially provide the outer surface bonded to the outer portion.

A method is provided of transmitting information with a communication protocol to a mobile device. A card reader is provided with a read head that has a slot for swiping a magnetic stripe of a card, an output jack and device electronics that includes a microcontroller. The read head is used to read data on a magnetic stripe of a card. A raw magnetic signal is produced indicative of data stored on the magnetic stripe. The raw magnetic head signal is converted into a processed digital signal that the microcontroller can interpret. A synchronous Manchester encoded stream is produced that makes a greater number of 0 crossings. A Manchester encoded stream output jack signal is delivered to the mobile device through the output jack.
