摘要:
An expandable, toroidal shaped bladder for use in a tire curing press has a pair of opposing annular beads and an expansion portion location between the pair of annular beads. The expansion portion of the bladder has a central portion, shoulder portions, and sidewall portions. When the bladder is in a mounted but uninflated mode, the shoulder portions of the bladder have a radius of curvature R1 significantly less than a radius of curvature Rc of the central portion. The shoulder portions have a bubble or square-like configuration.

An expandable bladder for shaping a pneumatic tire to be mounted inside a tire curing press has a pair of opposing annular beads and an expansion portion located between the pair of annular beads. The expansion portion of the bladder has a central portion, shoulder portions, and sidewall portions. When the bladder is in a mounted but uninflated mode, the shoulder portions have a radius of curvature less than infinity. At a distance (x) from each end of the central portion, the bladder has an increased thickness in the shoulder and upper sidewall portions.

An electrical system can selectively power a load via a USB connection or via another power source, such as a wireless power transfer path. An integrated switch controller determines whether to power the load via the USB connection or the other power sources and controls two external transistors via a single I/O pin connection to implement that determination. The switch controller determines the greater of two voltages: a voltage associated with the USB connection and a voltage associated with the other power source. The switch controller also determines whether there is a valid USB connection. The switch controller circuitry that controls the two external transistors is powered at the greater voltage to ensure that the external transistors are appropriately and securely turned on or off.

A voltage supply for providing a clamped voltage to a circuit element to be protected against electrical overstress (EOS) has a reference voltage module and a voltage clamp module. The reference voltage module has a first field-effect transistor (FET) whose source and drain are connected in series between a programmable reference current source and a first resistor across a power supply. The gate of the first FET is connected to its drain to provide a reference voltage defined by the reference current flowing in the first resistor. The voltage clamp module has a second FET whose gate receives the reference voltage and whose source is connected to provide to the protected circuit element the clamped voltage whose variation is limited by the reference voltage.

A true random number generator (RNG) has one or more oscillators and an output register for storing a random number output. Each of the oscillators is activated, successively, in a free-running oscillation phase, and a capture phase during which the oscillator is quiescent. The output register latches during the capture phase of each oscillator an end state of that oscillator at or close to the end of its oscillation phase. The random number output is derived from the latched end states.

Disclosed are surface-textured conductive glass for solar cells, and a preparation method and application thereof. In the surface-textured conductive glass for solar cells, a transparent conductive film is coated on a glass substrate, and the upper surface of the transparent conductive film is textured with nano/micro-scopic U-shaped pits uniformly distributed. The preparation method comprises: coating the transparent conductive film by magnetron sputtering, and then absorbing nano/micro-spheres onto the surface of the transparent conductive film as a mask by using an immersion coating method, followed by increasing the thickness of the transparent conductive film in gaps among the nano/micro-spheres by magnetron sputtering, and finally removing the nano/micro-spheres by using an ultrasonic vibration method to realize the large-scale and low-cost production of the conductive glass with nano/microscopic U-shaped surface texture. The conductive glass obtained by the method above has high repeatability, proper U-shaped texture feature size, high distribution uniformity, high production efficiency and low production cost, and thus is suitable for popularization and applications.

The present disclosure describes methods, systems, and computer program products for generic process modeling. One method includes identifying a business process for execution, the business process defined by one or more process steps, identifying a process routing table associated with the identified business process, at least a portion of the process routing table including one or more entries defining a set of business process rules for the identified business process, identifying a particular entry in the process routing table associated with a current state of the identified business process; and performing at least one action defined by the identified particular entry in the process routing table. In some instances, at least one entry in the process routing table is associated with one of a plurality of process patterns, with each process pattern comprising a reusable, predefined operation.
