Abstract: Cellular telephone handsets often include electronic or software coding that “locks” them to a specific wireless network. Provided herein, is a method for provisioning locked handsets by unlocking them from their established network and relocking them on a new cellular network. The handset is connected in communication with the control process, identified, and provisioned. The method allows for provisioning of multiple models and brands to be provisioned from different carriers and to different carriers. It further allows multiple handsets to be provisioned simultaneously. During the process, the handset may be sensitivity tested. Further, the identification portion of the method can be used in conjunction with phone support tools beyond the provisioning process.
Abstract: A surgical drape and suction head combination for attaching the suction head to a wound area. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to the aperture.

Abstract: A gradient sequential compression system for preventing deep vein thrombosis includes a pressure-based system controller for controlling transfers of air from a source of pressurized air to inflatable chambers of a limb sleeve, so that a prophylactic modality is provided to the limb. The controller also includes a plurality of feeder valves pneumatically connected to each of the chambers and a microprocessor-based control unit for opening only one of the feeder valves at a time during an inflation cycle, so that each of the chambers can be independently inflated to predetermined pressure levels. The control unit also regulates the pressures in each of the chambers at the respective pressure levels by repeatedly independently measuring the pressures in the chambers and adjusting the pressure levels upward or downward, if necessary. The predetermined pressure levels can be default levels or selected by a user or health care professional for a particular application.

Abstract: Method and apparatus for preventing bed sores in a bedridden patient. A low air loss bed is provided including a frame, a first set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame, and a second set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame, and all of the air bags are connected to a gas source. The conformation of the air bags is such that, when the first set of air bags is inflated, the patient supported thereon is moved toward the first side of the frame of the low air loss bed and, when the second set of air bags is inflated while the first set of ail bags is deflated, the patient is moved toward the second side of the low air loss bed. The conformation of the air bags also retains the patient on the top surface of the air bags when the patient is rolled in one direction or the other.
Abstract: A patient support system having multiple patient support layers for reducing and preventing the development of bed sores in bedridden patients. A top patient support surface is provided by an anti-shear cover layer. The anti-shear cover layer being operable to reduce lateral shear forces experienced by a patient moving across the patient support surface. One or more fluid pouches or bladders are provided to form a fluid bladder layer for reducing normal pressures and forces experienced by the patient. The fluid bladder layer being releasably or integrally secured to the top surface of an inflatable air mattress. Means are provided operable to secure the anti-shear cover layer and fluid bladder layer in overlapping relation to the inflatable air mattress. Also provided is a means for adjusting the temperature of the fluid contained within the fluid bladder layer.
Abstract: Systems and techniques for remediation of soil, vapor and groundwater contaminated with hydrocarbons. The system is ideally suited for easy integration into a mobile remediation unit that uses a liquid ring vacuum pump to extract a contaminated mixture from a sub-surface formation and direct it into a separator, which also serves to shield the high-flow vacuum pump from non-gaseous phases of the contaminated matter that would otherwise reduce its efficiency. Cooling systems are employed to render the unit more independent and self-contained, and an automatic vent and low-shear pump-down cycle is used to transfer liquid phases to fractionation subsystems with minimal emulsification.
