In accordance with the present invention, there is provided a garment or undergarment (e.g., a T-shirt) which is provided with integrated multi-layer perspiration barriers uniquely configured to provide high levels of evaporative cooling and moisture vapor transmission. The perspiration barriers are integrated into the sleeve and torso portions of the garment such that such perspiration barriers actually define the underarm portions thereof. Each of the perspiration barriers is preferably comprised of four layers, each of which is formed from two separate panel pieces. The various layers included in each of the perspiration barriers, the manner in which such layers are stacked upon and attached to each other, and the manner in which the layers forming each perspiration barrier are integrated into the garment are specifically adapted to collectively promote evaporative cooling and a vapor transmission effect which provides superior perspiration absorption and evaporation, in addition to enhanced user comfort.

A controlled differential, particularly for exercising steering control of skid steered vehicles, having a compound planetary gear set coupling two shafts. Respective ring gears turn with the shafts and mesh with a compound planet gear in a planet carrier, the ratios of the number of gear teeth between each ring gear and the respective gear of the compound planet being unequal so that when the planet carrier is stationary the two shafts are coupled through the differential to turn together in the same sense but with a speed difference, and controlled rotation of the planet carrier varies the speed difference between the shafts in accordance with the sense and speed of rotation of the planet carrier.

A shoe or article storage device, such as a shoe rack, includes a base and a shelf unit slidably mounted to the base for movement between a first position and a second offset position. The shelf unit is also rotatably mounted to the base for rotatable movement relative thereto. The shelf unit includes a first tier of article receptacles and a second tier of article receptacles stacked on top of the first tier. Each tier of article receptacles includes at least a first receptacle having a first receptacle access opening disposed at a first side of the shelf unit and at least a second receptacle having a second receptacle access opening disposed at a second, opposite side of the shelf unit.

Methods of generating a help files are presented including: accessing a user model, where the user model defines a number of objects and a number of relationships between the number of objects; selecting an object of the user model; receiving a text file corresponding with the object; creating a component of the help file from the text file; selecting an additional object of the user model, the additional object having a relationship with the object, the relationship corresponding with the number of relationships; and creating an additional component of the help file corresponding with the additional object. In some embodiments, methods further include: detecting a change to the user model; and regenerating the help file to incorporate the change. In some embodiments, methods are presented where the additional component includes: a link to the additional object, and a link to a respective text file of the additional object.

A liquid-cooled brake disc comprises a central stationary aluminium cooling plate (14) with an internal chamber (17) for the circulation of water or other liquid coolant, and a series of cast iron sectors (20) mounted on opposite sides of the plate for contact by conventional brake friction material carried by discs on a shaft to be braked (not shown). The cooling plate (14) and sectors (20) are separated by thin air gaps (22) or other thermally insulative layers. In use the sectors (20) have sufficient thermal capacity to store the heat generated by a braking event over a relatively short period, and this heat is then transferred to the coolant over a relatively longer period at a rate determined by the conductance of the air gaps. In particular this form of construction can absorb and dissipate the heat of braking without bulk boiling of the coolant.

Disclosed is an in situ design for a runoff rain gauge 14 comprising an elevated storage pan 18 for storing precipitation above grade, a splitter pan 28 for partitioning the split of flow from storage to runoff and infiltration, a saturation cup 40 for measuring surface saturation of the infiltration resistance medium and a saturation cap 42 and splitter balance line 38 for communicating water levels in the saturation cup 40 to the splitter pan 28.
摘要:
A gear change mechanism coupling a pair of shafts employs a planetary gear set comprising a sun gear fast with a first of the shafts, planet gears in a planet carrier, and an annulus or ring gear, the latter being fixed. A selector hub slidable on the other of the shafts has sets of radially spaced dogs to engage with corresponding dogs on the planet carrier and sun gear respectively, so as to couple the shafts at two different ratios depending on the axial position of the selector hub. This results in a more axially compact package than conventional dog clutch gear changers. In an alternative embodiment a reversing mechanism is provided by fixing the planet carrier and engaging the selector hub with the sun gear or annulus depending on its axial position.

In accordance with illustrative embodiments, methods and apparati, which determine jitter are described. In one example embodiment, a method includes receiving a signal, wherein the signal comprises a first data pattern which was generated at a first bit rate. The method also includes sampling the signal at a second bit rate to generate a second data pattern. The period of the second bit rate is different from the period of the first bit rate. The method also includes comparing the first data pattern and the second data pattern to determine differences between the first data pattern and the second data pattern. Furthermore, the method includes determining jitter in the signal according to the differences between the first data pattern and the data second data pattern. In other embodiments, by using two different bit rates to determine jitter, jitter can be determined in communication systems in a convenient and cost effective manner.
摘要:
An SRAM memory cell is provided having a pair of cross-coupled CMOS inverters. The sources of the pull-up transistors forming each of the CMOS inverters are coupled to VCC through parasitic resistance of the substrate in which each is formed. The source of the p-type pull-up transistor is therefore always at a potential less than or equal to the potential of the N-well such that the emitter-base junction of the parasitic PNP transistor cannot become forward biased and latch-up cannot occur.
