Abstract: A recovery network may provide communication recovery and backup services to an organization. The organization may comprise an internal network, such as Internet Protocol (IP) network. An alternative communication path communicatively couples communication devices of the organization to a public communication network. A recovery application operates on devices of the organization. The recovery network receives periodic availability indicators from devices within the organization. The recovery network identifies a communication endpoint of the intended recipient of a communication request using the availability indicators.

Abstract: A recovery network may provide communication recovery and backup services to a carrier having a service area. The recovery network may be configured to communicatively couple the carrier to the public communication network (PCN) using one or more alternative communication paths, such as a satellite network. The alternative communication paths may couple the recovery network to the carrier independently of the PCN. When the carrier detects a failure in its uplink to the PCN, it may failover to the recovery network, which may service the communication requests using the alternative communication path(s). Similarly, the recovery network may be used to service inbound communication requests directed to the carrier or other organization, such as a Public Safety Answering Point (PSAP). When used with a PSAP, the recovery network may be configured to access and/or provide metadata related to inbound communication requests.

Abstract: A recovery network may provide communication recovery and backup services to an organization. The recovery network may be communicatively coupled to the existing communication infrastructure of an organization via one or more alternative communication paths. The alternative communication paths may couple the recovery network to the organization independently of a public communication network. Upon activation of recovery services, the recovery network may receive communication requests directed to the organization from the public communication network. The recovery network may service one or more of the requests using one or more of the alternative communication paths. Similarly, the recovery network may service outbound communication requests originating at the organization over an alternative communication path. Communication requests may be backed up (e.g.

Abstract: An apparatus and method for improving performance in an internal combustion engine includes texturing on an inner surface of at least a portion of an engine head. The texturing may include elongated raised portions extending in one or more directions that may aid in controlling and directing pre-combustion and/or combustion gases in a combustion chamber for a more unified combustion. The result is improved power and/or efficiency.

Abstract: The performance of a leaf spring disc clamp can be enhanced by utilizing a roughly triangular shape for the center aperture. Such a disc clamp exhibits a substantially more uniform distribution of clamping force on the data disc and thereby reduces the deformation of the disc. It has further been determined that a stiffening rib located adjacent to the rim portion which contacts the data disc also leads to more uniform distribution of clamping force. Lastly, vibrations in a leaf spring disc clamp from external shocks or drive operation can be reduced utilizing a dampening ring of visco-elastic material. The dampening ring can be fastened to the surface of the disc clamp or placed within a rib on the disc clamp.

Abstract: A disc drive, includes a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a bearing housing, head mounting arms, head suspensions attached to the head mounting arms and a head assembly attached to the head suspension. The disc drive also includes a hub having a cylindrical body. The hub includes a disc mounting flange on one end of the hub. A disc has an opening therein sufficient to allow the hub to fit within the opening of the disc. The disc has two substantially flat data surfaces. The disc also includes a disc clamping portion located near the opening in the disc. A clamp is used to attach the disc to the hub. At least one disc is placed onto the hub and onto the mounting flange of the hub. The clamp is then used to clamp the disc to the hub. The disc clamping portion includes features for accommodating differences in flatness between the disc surfaces, the mounting flange of the hub and the clamp.

Abstract: An improved disc clamping system for the elements of the disc stack in a disc drive to increase resistance to radial shifting of the disc stack elements. The increased resistance to radial shifting is achieved by increasing the coefficient of friction between adjacent disc stack elements, and the increase in the coefficient of friction is accomplished by controllably texturing the contact surfaces of various disc stack elements or combinations of disc stack elements. Surface texturing processes particularly suited to specific disc stack elements are disclosed.
