Abstract: Embodiments of the present invention are directed to a method for creating an electronic log for documenting entries into electronic gaming machines on a network. The network is monitored by a network computing device. People who enter the machines carry mobile computing devices that communicate over a normally operating wireless network. Cooperating among the network computing device and the wireless network results in creating an entry that includes the identify of a person entering one of the gaming machines, the identity of the gaming machine entered, and the reason for entry. The entry is stored in an electronic log.

Abstract: Anti-fog compositions comprising a primary film having opposing major planar surfaces and a central coplanar region, and processes for making such anti-fog compositions. The central coplanar region is disposed between the opposing major planar surfaces. The primary film comprises cellulose acetate, plasticizer, and an anti-blocking agent. The anti-blocking agent has an average particle size ranging from 0.02 microns to 6 microns. The cellulose acetate has a degree of substitution that increases from the opposing major planar surfaces toward the central coplanar region or that is substantially constant throughout the thickness of the composition. The composition is formed by saponifying a precursor film to improve hydrophilicity.

Abstract: Embodiments of the present invention are directed to a method for dispatching a person to a location in a casino to respond to a request for service at the location. A listing of persons who may be dispatched to various locations is stored on in a database. At least some of the persons are associated with a primary qualification for the type of service that he or she may provide. A communication on a network of gaming devices is received indicating that service is required a particular location. A signal is automatically sent to a wireless device carried by a person having an appropriate qualification to provide the service. Player tracking data is also sent to permit the provider to personalize the service.

Abstract: Integrated jitter compliant clock signal generation apparatus and methods are provided. Input signals having different frequencies are used to generate respective clock signals having closely spaced frequencies. The input signals might be generated, for example, in adjacent Phase Locked Loops (PLLs) which receive reference clock signals. The reference clock signals, or signals from which the reference clock signals originate, are also closely spaced. The closely spaced reference clock signals are effectively separated for cleanup and then brought back together to provide the closely spaced clock signals. This allows cleanup of the closely spaced reference clock signals to occur at staggered and more widely spaced frequencies. These techniques could also be applied to reference clock signals which are harmonically related and are used to generate harmonically related output clock signals.

Abstract: A phase difference between a reference clock signal and a feedback signal is digitally detected. A resultant phase detection signal is digitally filtered, and a PLL (Phase Locked Loop) output signal is synthesized in a fractional synthesizer under control of the digitally filtered phase detection signal. A feedback path, which could include an integer divider and/or a fractional N divider, provides the feedback signal based on the PLL output signal. The combination of a wide bandwidth fractional synthesizer and a low bandwidth digital PLL provides for a low bandwidth jitter filtering function with a wide bandwidth PLL to suppress VCO (Voltage Controlled Oscillator) noise and crosstalk.

Abstract: Embodiments of the present invention comprise methods and devices for amplifying a signal by amplifying a first signal and by then amplifying a second signal only if the first signal exceeds a predetermined threshold. The first and second amplified signals are then combined, and the combination is fed back to a signal source and used to control the values of the first and second signal. The combination is further transmitted to a load. In the preferred embodiment, the first amplified signal is transmitted through an impedance inverter before it is combined with the second amplified signal.

Abstract: A method of fabricating a book from a bound stack of sheets and a hardcover assembly having first and second relatively rigid cover sections separated by a spine region. A layer of pressure sensitive adhesive is disposed over the inner surfaces of the cover sections, with there being a pair of release liners covering both the pressure sensitive adhesive layers. The book is assembled by placing the hardcover assembly on a surface and removing one of the release liners from one of the pressure sensitive adhesive layers. The bound stack is then positioned on the hardcover assembly, preferably using a guide apparatus to ensure proper positioning, so that the one end sheet of the stack and the and assembly will become attached by the exposed pressure sensitive adhesive. The stack is then folded away from the hardcover assembly in a manner such that the user can access and remove the second release liner thereby exposing the remainder of the adhesive on the one cover section.

Abstract: A stitched hardcover book and method of making same wherein the stitching is at least partly concealed. A stack of sheets to be bound is disposed intermediate first and second end leafs, with each of the end leafs including an attached reinforcing strip extending along an edge of the end leaf. The combined assembly is provided with stitching which extends through the stack and the reinforcing strips. The first and second end leafs are secured to an inner surface of respective first and second covers of a hardcover assembly, with the components of the hardcover book being configured such that when the first and second cover sections are positioned in a common plane, a bound end of the sheets of the stack is disposed on a first side of the common plane, with the sheets extending to an opposite second side of the common plane and with the stitching line being disposed on said first side of the plane.

Abstract: Apparatus and method for conditioning an edge of a sheet to be bound so that the edge is conducive to accepting heat activated adhesives used in conventional binding. The sheet is first bent in one direction to form a folding line, with the fold line being a short distance from the edge of the sheet to be conditioned and with that distance being determined primarily by the thickness of the sheet. The bend in the sheet is typically 90 degrees, with the radii of curvature of the opposite sheet surfaces at the fold line being unequal so that a shear force is applied near the sheet end thereby tending to tear or fracture in interior of the sheet near the end. Typically the sheet is then bent in an opposite direction along the folding line so as to produce an opposite shear force that reinforces the creation of tears and fractured in the sheet.

Abstract: An improvement for a phasor fragmentation engine and method, whereby a phasor flipping algorithm is applied when determining fragment phasors for a non-constant envelope modulation signal (e.g. OFDM). The phasor flipping algorithm avoids sharp phase transitions for the fragment phasors, which cause an increase in bandwidth, by performing a comparison of the phasor angle separation between the prior and current time samples. This comparison corresponds to a determination of whether the modulation signal V has passed near or through zero.

An operating mechanism is structured to open the separable contacts responsive to the trip signal.

Abstract: Apparatus and method of increasing adhesion of thermal binder strips to coated papers by conditioning an edge of the sheet by splitting the edge which results in an expansion of the edge followed by compressing the edge so as to reduce or eliminate the expansion. In the case of a stack of sheets, the edge of the stack is conditioned by piercing the edge of the stack and in the case of an individual sheet, the conditioning is carried out by splitting at least a portion of the edge of the sheet.

Abstract: An arc fault circuit breaker includes line and load terminals, separable contacts electrically connected between the terminals, a current sensor adapted to sense current associated with a load and flowing between the terminals and through the separable contacts. An arc fault detection circuit provides series arc protection and generates a trip signal responsive to the sensed current. The arc fault detection circuit collects a plurality of samples of the sensed current over plural line cycles, determines that the load is a dimmer-controlled load, determines a phase angle at which the sensed current begins conduction within one of the line cycles, and determines that the phase angle consistently moves in a forward direction or a reverse direction. If so, then series arc protection is responsively inhibited. An operating mechanism opens the separable contacts responsive to the trip signal.

Abstract: An arc fault detection circuit collects samples of sensed current, determines a peak current value from the samples for each line cycle, determines a hysteresis value for a compressor load as a function of differences between the peak current values, and generates a trip signal responsive to the sensed current and the hysteresis value. The circuit determines a difference value for each line cycle from the present peak current value less the previous peak current value, low pass filters the difference value to provide a low pass filtered value, determines a peak value from the low pass filtered value, determines that the absolute value of the low pass filtered value is less than a portion of the peak value and responsively saves the peak value, and determines the hysteresis value as a function of the saved peak value. An operating mechanism opens separable contacts responsive to the trip signal.

Abstract: An arc fault circuit interrupter includes separable contacts electrically connected between line and load terminals, and a current sensor adapted to sense current flowing between the terminals and through the contacts. An arc fault detection circuit is adapted to collect a plurality of samples of the sensed current for a line cycle, determine a first slope of the sensed current at about a zero crossing of a line voltage, determine a magnitude of one of the samples at about the zero crossing, determine a second slope of the sensed current at another one of the samples having about the magnitude, with the first slope being opposite in polarity with respect to the second slope. The arc fault detection circuit calculates a difference between the slopes, and generates a trip signal as a function of the difference. An operating mechanism is adapted to open the contacts responsive to the trip signal.
