Abstract: A toner cartridge according to one embodiment includes a housing having first and second alignment guides that extend outward from a first side and a second side of the housing, respectively, and that run along a front-to-rear dimension of the housing. Third and fourth alignment guides extend outward from the first side of the housing. The third alignment guide is spaced toward the front of the housing from the fourth alignment guide. Bottom surfaces of the third and fourth alignment guides are unobstructed to sit on top of a corresponding guide surface in an image forming device to control a vertical position of the toner cartridge in the image forming device. The bottom surfaces of the third and fourth alignment guides are aligned with each other in a vertical dimension of the housing and are positioned higher than the first and second alignment guides.

Abstract: A replaceable unit for an electrophotographic image forming device according to one example includes a housing having a toner reservoir. An electrical connector mounted on the housing is movable between a retracted position and an operative position. The electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device. The electrical contact is electrically connected to processing circuitry on the housing. In the retracted position, the electrical connector is tucked into a portion of the housing. In the operative position, the electrical connector is exposed to permit the electrical contact to contact the corresponding electrical contact in the image forming device. A linkage is operatively connected to the electrical connector and includes an engagement surface accessible on an exterior of the housing to receive an actuation force. Movement of the linkage moves the electrical connector between the retracted position and the operative position.

Abstract: Methods and apparatus controlling a wireless power transmitter by applying a first low-side driver signal to a first channel in a first pair of channels and applying a first high-side driver signal to a second channel in first pair of channels, wherein each driver signal has a state that is “active” or “inactive” and drives a transistor gate of a switching element. The state of each driver signal on each channel can be monitored to detect an error condition to prevent damaging current flow condition to the switching elements. When the error condition is detected, at least one of the driver signals may be set to “inactive” for a period of time.

Abstract: A gardening tool may have a handle coupled to a head by way of a connector. The head may comprise a detachable, double-edged blade having a plurality of spikes. The head may include a second blade with a plurality of prongs of varying lengths. The smaller size of the gardening tool relative to many conventional tools may improve efficiency for the use, transportation, and storage of the tools.

The electrical connector and the electrical contact of the toner cartridge move upward toward the top of the housing when the electrical connector moves from the retracted position to the operative position. The electrical contact of the toner cartridge is positioned within a pocket of the electrical connector. The pocket includes an opening that faces upward when the electrical connector is in the operative position permitting the corresponding electrical contact in the image forming device to enter the pocket from above.

Abstract: The disclosure features high-resolution pulse-width modulation (HRPWM) controllers that can include a first channel having a first coarse_on register and a first coarse_off register and a counter configured to determine a repetition rate for the first channel. When a coarse_on value of the first coarse_on register and the counter are equal, the first channel can be set “active” and when a coarse_off value of the first coarse_off register and the counter are equal, the first channel can be set “inactive”. The controllers can include a delay line configured to generate a set of delay locked waveforms offset by a fine resolution value and a control module configured to select a delay locked waveform from the set of delay locked waveforms and apply the selected delay locked waveform to the first channel.

Abstract: A system, method, and fluid analysis module are provided for the real-time analysis of multiphase fluids. The system generally comprises a sampling system for directing a fluid stream from a flow line to a fluid analysis module, a processor and communicator. The fluid analysis module comprises a sensor for measurement of at least one property of the fluid. The processor processes the measurement data from the sensor, and the communicator communicates the processed data to a central acquisition unit or computer.
