Abstract: An apparatus and a method of optimizing voice quality on a network having end-points that are voice over Internet Protocol (IP) devices. Default parameters of the end-points are initialized. Network performance parameters are measured and evaluated to determine whether they signify that connection to the network is below a desired level of operation. If so, the default parameters of the end-points are re-set based on the evaluation. The adjustment may entail re-negotiating the CODEC connection and re-setting parameters for packet size and resetting parameters for jitter buffer size.

Abstract: An automated cartridge library has an essentially rectangular library frame which includes a frame front wall (22) and a frame back wall (24), and a library door (30) provided on the frame front wall. A transport actuator and guide region (90) is provided within the frame, the transport actuator and guide region including both a guideway along which a cartridge transport assembly (92) reciprocates and an actuator (124) which causes the cartridge transport assembly to rotate from a first transport position to a second transport position. A library front section includes a cartridge magazine cavity (50) and a entry/exit port module (54). A library rear section includes a region for tape drives (60) and an auxiliary cartridge magazine (70). Cartridge magazines (64) are insertable into the cartridge magazine cavity when the library door is opened so that a reference surface of the cartridges face the transport actuator and guide region.

Abstract: A robotic cartridge picker (92) for a cartridge library (20) has picker fingers (84) for selecting engaging and disengaging a media cartridge (64), and an electronic device (180) carried thereon. A ribbon cable (182) supplies at least one of power and an electrical signal to the electronic device. The robotic picker is rotatably mounted on a mounting block (140). The mounting block has a chamber (188) wherein a portion of the ribbon cable is carried in a variable coiled configuration to accommodate rotation of the robot about an axis (100). The variable coiled configuration facilitates the ribbon cable having a first degree of coiling when the picker robot rotates to a first position and a second degree of coiling when the picker robot rotates to a second position.

Abstract: A cartridge library comprises plural cells for accommodating therein a cartridge of information storage media and a tape drive which transduces information relative when a cartridge is loaded into the drive. A cartridge loader (also known as the cartridge transport assembly) is mounted to the drive assembly for picking a selected cartridge from one of the cells and for inserting the selected cartridge into a cartridge slot in the drive. The drive assembly is stationary but the cartridge loader is pivotal about the drive assembly, and particularly about a pivot axis which is parallel to a center line of the data cartridge when the data cartridge is inserted into the drive assembly. The drive assembly includes a toothed transport track engageable by the cartridge transport assembly for incremental pivotal motion of the cartridge transport assembly about the pivot axis.

Abstract: An automated library which handles cartridges of information storage media includes a magazine (40) which comprises a cartridge engaging member (1428) which deflects to preclude insertion of the magazine into a magazine cavity (840) in the library frame (36) when the cartridge is improperly inserted into the magazine. The magazine defines a cell for the cartridge and comprises a magazine wall (1420) from which cell partitions (1410) extend. The cartridge engaging member (1428) is a cantilevered arm having a distal end extending in a direction into which the cartridge is insertable into the cell, and has a cartridge engaging profile whereby, when a cartridge (C) is properly inserted into the cell, the cantilevered arm does not extend beyond a reference plane but when the cartridge is not properly inserted the cantilevered arm deflects beyond a reference plane.

Abstract: An infant restraint system including an infant carrier, a base couplable to the infant carrier via an improved locking mechanism and having an improved recline mechanism. The infant restraint system further includes an improved handle and an improved belt system, the belt system having a mid-belt adjuster disposed in front of the infant when the infant is positioned in the infant restraint system.

Abstract: A pneumatic compliant tape guidance device for pneumatically applying a biasing load to a passing tape media. The tape guidance device includes at least one guide button and associated cylinder in which the guide button travels. It also includes a supply port which provides the input for a pressure and/or a vacuum to a pressurized chamber which couples the supply port with the cylinder. The guide button position and its applied pressure are controlled by a compressor which controls the amount of air pressure applied to the guide button through the supply port. The pneumatic compliant tape guidance applies pressure to the top edge or bottom edge of the tape media. The guide button may be configured to travel over a support tube which transfers the pressure/vacuum applied at the supply port to the guide button. The amount of pressure the guide button applies to the passing tape media is determined by the pressure/vacuum which is applied by a pneumatic source to the supply port.

Abstract: Robot gripper jaw apparatus is disclosed that is suited for grasping a media cartridge in a robot-controlled media library, or for grasping other objects. The gripper jaw apparatus employs a novel circular cam which reduces the amount of torque required to operate the gripper jaws. This allows use of a relatively small servo motor. The use of a circular cam additionally decreases the overall size and complexity of the gripper apparatus as compared to conventional gripper mechanisms. The gripper apparatus provides for an easily controllable robot gripper jaw mechanism for grasping a media cartridge wherein the force applied by the gripper jaw mechanism does not damage the media cartridge being grasped, due to the use of a flat spring which limits the force applied to the media cartridge. In addition, the gripper apparatus does not require that the gripper drive servo motor be reversed in order to release the media cartridge. Therefore, the gripper jaw servo motor need only rotate in one direction.
