Abstract: A non-slip jewelry display having a tacky top surface such that jewelry items cling to the display in a frictional fashion; thereby preventing shifting or sliding of the jewelry item on the display when moved or otherwise jolted about.

Abstract: A crimp tool and crimp arrangement for connecting a clip onto a snowmobile tread. The snowmobile tread and clip once connected together are positioned in cooperating engagement with the suspension of a snowmobile. The crimp tool implements a pneumatic actuator having a shaft with a transverse axle that is in operable engagement with bearing surfaces of the two press levers. The transverse axle causes the two press levers to pivot about pivot posts between a crimped and uncrimped position. When a clip for connection to the tread of the snowmobile is positioned between the crimp ends of the two press levers, the clip can be bent from an uncrimped position to a crimped position by the crimp ends, thereby connecting the clip to the tread of the snowmobile.

Abstract: An article display and method of use thereof, comprising a magnetic article display for releasably attaching two or more jewelry displays together or to a platform, to provide an article display set, wherein any display can be easily separated from the article display set; thereby providing for individual viewing of the removed article display and/or rearrangement of the remaining article displays within the article display set.

Abstract: The electronic properties of molecular junctions of the general type carbon/molecule/TiO2/Au as examples of “molecular heterojunctions” consisting of a molecular monolayer and a semiconducting oxide. Junctions containing fluorene bonded to pyrolyzed photoresist film (PPF) were compared to those containing Al2O3 instead of fluorene, and those with only the TiO2 layer. The responses to voltage sweep and pulse stimulation were strongly dependent on junction composition and temperature. A transient current response lasting a few milliseconds results from injection and trapping of electrons in the TiO2 layer, and occurred in all three junction types studied. Conduction in PPF/TiO2/Au junctions is consistent with space charge limited conduction at low voltage, then a sharp increase in current once the space charge fills all the traps. With fluorene present, there is a slower, persistent change in junction conductance which may be removed by a reverse polarity pulse.

Abstract: A method and device for hiding refresh operations during accesses to sub-arrays of a pseudo-static memory device. By refreshing sub-arrayj while filling the row Ri (where i?j) corresponding to sub-arrayi, refresh operations can be performed without risking that a read request will interrupt the refresh operation. Additional refresh operations of sub-arrayi can be performed serially with the operations of filling the row Ri without delaying the overall burst read or write operation if the burst is made sufficiently long.

Abstract: An enhanced DRAM contains embedded row registers in the form of latches. The row registers are adjacent to the DRAM array, and when the DRAM comprises a group of subarrays, the row registers are located between DRAM subarrays. When used as on-chip cache, these registers hold frequently accessed data. This data corresponds to data stored in the DRAM at a particular address. When an address is supplied to the DRAM, it is compared to the address of the data stored in the cache. If the addresses are the same, then the cache data is read at SRAM speeds. The DRAM is decoupled from this read. The DRAM also remains idle during this cache read unless the system opts to precharge or refresh the DRAM. Refresh or precharge occur concurrently with the cache read. If the addresses are not the same, then the DRAM is accessed and the embedded register is reloaded with the data at that new DRAM address.

Abstract: A memory and method for operating it provide for increased data access speed. In an implementation, a synchronous memory or SDRAM includes a central memory region with memory blocks arranged in sets on respective opposite sides. A number of primary sense amplifier sets are provided, each set being associated with a respective set of the memory blocks and located adjacent. A row cache is provided in the central memory region, and row decoders decode a row address in response to a “bank activate” command and move data from a decoded row address into a primary sense amplifier set associated with a memory block containing the decoded row address and into the row cache, before application of a “read” command to the SDRAM. Column decoders decode a column address in response to a “read” command and for reading data from the cache in accordance with the decoded column address.

Abstract: A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The controller compares detected breath alcohol levels of the vehicle operator with a threshold value, and is configured to prevent vehicle ignition if a breath alcohol level detected by the breath analyzer is greater than or equal to a threshold value. The controller also requires the vehicle operator to periodically take breath analyzer retests after vehicle ignition in order to allow vehicle operation to continue. The controller can reduce the frequency of periodic retests in response to one or more retests when the breath alcohol level of the vehicle operator is below a threshold value. The system may include a transdermal alcohol sensor, a mouth contamination sensor, a mouth contamination sensor, and redundant alcohol sensors.

Abstract: A vehicle ignition interlock system includes a breath analyzer, a transdermal alcohol sensor configured to be worn by the vehicle operator, and a controller operably connected to the breath analyzer, to the transdermal alcohol sensor, and to an ignition system of the vehicle. The transdermal alcohol sensor is configured to be worn by the vehicle operator, and is configured to detect alcohol through the skin of the vehicle operator. The controller is configured to override one or more periodic breath analyzer retests if alcohol is not detected through the skin of the operator by the transdermal alcohol sensor. The controller is configured to increase the frequency of periodic breath analyzer retests of the vehicle operator in response to the transdermal alcohol sensor detecting alcohol through the skin of the operator. A proximity sensor detects proximity of the transdermal alcohol sensor relative to a vehicle operator area.

Abstract: A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects breath alcohol level of a vehicle operator and prevents vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer “retests” after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer includes first and second alcohol sensors. The second alcohol sensor is a backup for the first alcohol sensor and becomes operational if the first alcohol sensor malfunctions. The first or second alcohol sensors may be a mouth contamination sensor that distinguishes between mouth contaminants and alcohol contained within a deep lung breath sample. The system also includes sensors configured to detect impact (abuse) and vehicle motion.
