Abstract: Traffic flows through an administered network from an off-network source and/or to an off-network destination are simulated and analyzed by selecting an ingress and/or egress node within the administered network, the ingress node capable of collecting traffic from an off-network source, and the egress node capable of routing traffic to an off-network destination. Traffic flow is mapped from the source or ingress node through the administered network to the egress node. The traffic flow may be simulated and analyzed. The ingress and/or egress nodes may be selected in a variety of ways.

Abstract: This invention can generally be described as an overall transmit (TX) scheduler state-machine that is broken down into two different state-machines: One first TX-scheduler state-machine (FTSM), executed in software, and one second TX-scheduler state-machine (STSM) executed in hardware, which is operating in four different basic states. The functional partitioning between the two state-machines is such that the most constrained real-time requirements are allocated to the STSM, while all complex decisions and non time-critical controls are allocated to the FTSM. The invention also relates to a terminal comprising the invented transmit scheduler.

Abstract: An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a driven toner distributing member that distributes accumulated toner within the container. The toner distributing member may be driven by a shared speed-controlled motor that further drives an image forming process member. The waste toner system may detect the accumulation of waste toner by monitoring a drive control circuit while the toner distributing member is being driven. For example, a logic circuit may detect the accumulation of waste toner based on monitoring a predetermined frequency of interest of a frequency domain transform of a motor control signal, the frequency of interest associated with the shared motor driving the toner distributing member.

Abstract: The white vector—the voltage difference between white areas of a latent image on a photoconductive unit and a developer roller—may be independently adjusted at each photoconductive unit, allowing multiple image forming units to be driven from a shared power supply. The photoconductive unit is charged to a high voltage level relative to the developer roller, and selectively optically discharged to the desired white vector by a first laser source. The voltage of the discharged area may be measured, or may be calculated by increasing the developer roller voltage a predetermined amount, discharging the photoconductive unit until toner is sensed in white image areas, and then reducing the developer roller voltage. The white areas are discharged using a different light source, such as a laser, LED or electroluminescent source. A second laser may be of a different wavelength than a writing laser.

Abstract: A lens has a lens body (1), reinforcing extensions (3a, 3b) and a clear aperture (9) surrounded on top and bottom by lens body. The lens is suitable for spot scanning. The lens is made of a water absorbing material, such as most polymers, particularly acrylate polymers. Aluminum sheets as vapor barriers are attached on each side of the lens body. This results in excellent resistance to change or distortion in high humidity environments.

Abstract: A device to regulate toner within an image forming apparatus. The regulating member has a first section and a toner regulating edge with at least one gap. The regulating member controls the amount of toner that is distributed on the surface of the toner developer roller by contacting the toner developing roller in a contact region. The gap, having at least one upper edge, may regulate toner on the toner developer roller near the contact region. The toner regulating device may prevent inadvertent toner marks that may appear on printed media.

Abstract: An image forming device having a main body and a movable subunit. The subunit is movable between a first orientation and a second orientation. A developer member is positioned within the main body, and a photoconductive member is positioned on the subunit. In the first orientation, the developer member and photoconductive member are spaced apart. In the second orientation, the photoconductive member is positioned either in contact with or closely located to the developer member. Image formation occurs when the subunit is in the second orientation as toner is transferred from the developer member to the photoconductive member. Methods of using the image forming device include positioning the developer member in the main body and the photoconductive member on the subunit, and moving the subunit from a first orientation to a second orientation such that image formation can occur.

Abstract: A connector for interconnecting two building members together. The connector, in one embodiment, includes first and second plates secured together. Each plate includes one or more elongated slots wherein the elongated slots of one plate are oriented at an angle of approximately 90° with respect to the slots formed in the other plate. Fasteners extend through the slots in the plates and connect the plates of the connector to two building members such as a horizontal building member and a vertical building member. Once connected, one of the building members is free to move with respect to the other building member while the connector is connected to the two building members. In another embodiment, the connector is slidable within a track. In this embodiment, a portion of the connector extends from the track and connects to one of the building members while the track connects to the other one of the building members.

Abstract: A process and system for treating excess sludge produced from a biological treatment system. The process includes biologically treating water or wastewater and producing excess sludge. The excess sludge is directed to a solubilizer where the sludge is solubilized. The solubilized sludge is directed to a liquid/solid separator, which separates the solubilized sludge into a liquid fraction and a solid fraction. The process further includes at least partially digesting the liquid fraction and directing the partially digested liquid fraction to the biological treatment system where the liquid fraction is subjected to further treatment. Finally, the solid fraction is subject to further solubilization.

Abstract: A demodulator operates in a multipath (ISI) channel carrying transmitted symbols. The demodulator receives a signal representing a transmitted sequence, and develops an output sample at a select sampling phase corresponding to a synchronization point. Plural hypothetical samples representing plural hypothetical sequences are generated. The output sample is compared to the plural hypothetical samples to determine plural metrics and develop an original estimate of each transmitted sequence based on the hypothetical sequence producing a best metric. The hypothetical samples are compared to the received sample taken at an early sampling phase in advance of the select sampling phase and to the received sample at a late sampling phase delayed from the select sampling phase to determine if a second estimate of the transmitted symbol produces a better metric than the original estimate, and in response to the second estimate producing a better metric adjusting the synchronization point.

The circuit includes a control device receiving amplitude information and phase information from a primary waveform, a plurality of switching devices in communication with the control device and the amplifier, wherein each of the switching devices has a different “ON” resistance. The control device uses the amplitude information to select an active switching device and to control the device using phase information to create a secondary waveform for input to the load matching network. In this way, an amplitude modulated waveform is amplified at high efficiency, enabling application of either all or part of the phase and/or amplitude modulation at the input of the amplifier.

Abstract: A locating unit includes a wireless communications interface for transmitting signals to one or more locating tags. A user physically associates each tag with an item of interest, such as a briefcase or key ring. When a tagged item is misplaced, the user uses the locating unit to find it. Using the user interface included in the locating unit, the user selects the desired item from a listing of tagged items. Based on the user selection, the locating unit polls the associated tag. The polled tag responds by emitting an audible signal, thereby aiding the user in determining its location. Preferably, the locating unit is a mobile terminal and communications between the mobile terminal and individual tags is two-way. Thus, a polled tag returns a found signal to the mobile terminal in response to being polled.

Abstract: An RF amplifier for a transmitter develops a phase modulation command representing a desired phase modulation of an RF signal, and an amplitude modulation command representing a desired amplitude modulation of the RF signal. An oscillator develops an RF input signal phase modulated based on the phase modulation command. A power amplifier receives the RF input signal and amplifies the RF input signal based on the amplitude modulation command to develop an RF output signal. A modulation control is operatively associated with the oscillator. The modulation control includes a phase memory for storing phase correction information correlating the amplitude modulation commands to a phase modulation error and a phase control for varying the phase modulation command based on the phase modulation error to correct for unintended phase errors created by amplitude modulation of the power amplifier.
