    Abstract: The present application is directed to retainers and methods of retaining a developer unit within an image forming device. One embodiment may include positioning a retainer attached to a frame at a first position with a second end of the retainer positioned away from the developer unit. A toner cartridge may be inserted into the image forming device in a vertical direction and contact against retainer. The toner cartridge may laterally move the retainer relative to the frame from the first position to a second position with the second end positioned to prevent removal of the developer unit from the frame. Another embodiment features a system to retain a developer unit in an image forming device. The system may include a frame configured to receive the developer unit and the toner cartridge. A retainer may be movably attached to the frame and include a first end with a ramped surface, and a second end spaced away from the first end. The retainer may be movable between a first position prior to insertion of the toner cartridge with the second end positioned away from the developer unit, and a second position after insertion of the toner cartridge with the second end positioned to prevent removal of the developer unit from the frame.

    Abstract: A method for optimizing the capacity of a forward link in a cellular telecommunications network involves dynamically setting the minimum gain level on the forward link for each mobile station, based each mobile station's individual performance. The cellular network has one or more base stations and a mixed population of single-diversity mobile stations and dual-diversity mobile stations. In communicating with a particular mobile station, the gain level of the transmission over the forward link is monitored at the base station. The base station also monitors the reverse link for a power measurement report message (“PMRM”) sent by the mobile station. If the gain level stays at or close to a minimum gain level for a certain time period, and if no PMRM″s are received during that time period, then the base station reduces the minimum gain level by a set amount. The reduction in the minimum gain level can be triggered based on other factors, such as the forward link frame error rate.

    Abstract: A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when Eb/No measurements for served mobiles do not meet target Eb/No levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target Eb/No levels in a centralized manner based on an overall system state so that only a limited number of target Eb/No levels are allowed to increase when frame erasures occur. By preventing a percentage of target Eb/No level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.
