Abstract: A computer-implemented method of providing one or more content item recommendations for a user of a content distribution system, comprising: determining if a user search using a title of content finds the title of content in one or more content sources available to the user; identifying, in response to the title of content not being found in the one or more content sources, content in a content library by determining if the title of content is in the content library, wherein the content library contains metadata concerning items of content in the content library, the metadata representing at least some properties of the items of content; using, in response to the title of content being determined to be in the content library, the metadata of the identified content in the content library and metadata concerning content available from the one or more content sources available to the user to generate at least one content item recommendation for the user, wherein the at least one content item recommendation is fo

Abstract: Component-level, scene-based power management in a test, monitoring, or measurement instrument or system is provided by identifying one or more controllable components; determining a power consumption of the identified one or more controllable components; generating a system model based, at least in part, on the determined power consumption, where the system model includes one or more scenes, each scene defining a list of controllable components and respective power states for the list of controllable components; generating a scene table for the test instrument by selecting a plurality of scenes from the system model; and executing the selected scenes in the scene table at a runtime for the test instrument, where each scene is executed based on an operation mode of the test instrument.

Abstract: A casing for a shaft assembly, a shaft assembly, a method of forming a casing, and a drive assembly. The casing may generally include a liner defining a central passage and having a body and an outwardly-extending leg (e.g., extending circumferentially about and/or axially along the body), and a cover extending circumferentially about and axially along the liner.

Abstract: A heat exchanger includes a core and a pair of end tanks attached to the end of the core. Each end tank extends over an outermost peripheral end of the core such that the core extends into a chamber defined by the end tank. The end tank is welded to the core at the outer surface of the core and a lower end surface of the tank.

Abstract: A fuser assembly for an electrophotographic imaging device includes a heater including a substrate, a resistive trace disposed and running along a length of the substrate for generating heat for fusing toner to a sheet of media when a current is passed therethrough, and at least three conductors for passing current through the resistive trace. The at least three conductors include a first conductor connected to a first end portion of the resistive trace, a second conductor connected to a second end portion of the resistive trace, and a third conductor connected to the resistive trace at a location between the first end portion and the second end portion thereof. A temperature sensor senses a temperature of an edge segment of the substrate. Based upon the temperature sensed, circuitry selects between the first conductor and the third conductor for passing current through the resistive trace.

Abstract: In bi-directional imaging, such as bi-directional printing, a driving mechanism scans a light beam through a scan path across an imaging window. A controller enables transmission of video data to a modulator when the light beam is positioned for imaging on the imaging window. Video data is transmitted to the modulator when the light beam is traveling in a forward direction or a reverse direction across the imaging window, whereby a modulated light beam is capable of producing an image when traveling in the forward or reverse directions. The controller adjusts scan durations or image rasterization rates to ensure that each scan is properly aligned with the prior and subsequent scan.

Abstract: A method for operating a torsion oscillator at its resonant frequency. The method performs an open-loop frequency sweep starting with nominal operation parameters saved from the factory or from a previous operation of the torsion oscillator. The sweep determines an open-loop resonant frequency and an open-loop drive level. A closed-loop resonant frequency sweep is performed and a closed-loop steady-state resonant frequency is determined. This frequency is used to calculate a closed-loop overshoot and a closed-loop steady-state drive level. The torsion oscillator is then operated in a closed-loop mode at the closed-loop steady-state resonant frequency and starting at the closed-loop steady-state drive level. Finally, the nominal operation parameters are updated and stored in non-volatile memory. The method minimizes the effects of ambient environmental conditions including air density on the steady-state operation of the torsion oscillator.

Abstract: A circuit includes a switching device for controlling a power signal to be applied to a heating device. A control circuit is configured for comparing a temperature signal, indicative of the temperature of the heating device, to a temperature setpoint to generate a gate pulse signal that controls the duration of the power signal to be applied to the heating device. The control circuit is further configured for comparing the duration of the power signal to be applied to the heating device to a minimum pulse duration and, if the duration of the power signal to be applied to the heating device is at least equal to the minimum pulse duration, providing the gate pulse signal to the switching device.

Abstract: A bi-directional electrophotographic raster imaging system that sweeps a modulated light beam across an imaging region of a photosensitive surface to create both forward-going and reverse-going scanlines of dot data on the imaging region, and which compensates for image misalignment that may be caused by varying the power used to drive a laser light source that generates the modulated light beam. An SOS photosensor detects the beginning of each scanline in both forward and reverse directions, outputting an SOS signal used to create both forward and reverse margins. When the laser power is varied, compensating data is used to correct the forward and reverse margins to keep them aligned (straight), even though the beginning of the scanline locations for both forward and reverse scans are affected in opposite directions by an increase or decrease in laser power.
