Removable wound closure

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material (36) enclosed by sheets of elastomeric material (38) punctuated by a number of appropriately placed holes (34). Multiple layers of porous foam may also be used. A suction tube connector (16) is provided on an upper surface of a layer of foam (12) for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope, and through the foam. If multiple foam layers are employed, the lower layer(s) of foam are of a finer porosity while the upper layer of foam is coarse. An adhesive elastomeric sheet (14) covers the entire wound dressing and seals the edges to the skin surrounding the wound. An appropriate vacuum device is attached to the suction tube connector.

System and method for performing network re-entry upon handover of mobile subscriber station in a broadband wireless access communication system

A system for performing network re-entry upon handover of a mobile subscriber station (MSS) to a target base station (BS). Upon detecting handover of the MSS, the target BS detects network re-entry information necessary for network re-entry of the MSS from the serving BS, and transmits, to the MSS, the detected network re-entry information, information on an acknowledge (ACK) channel through which the MSS will respond that it has received the network re-entry information upon receipt of the network re-entry information, and ACK request information requesting the MSS to respond whether it has received the network re-entry information. The MSS receives the ACK channel information, and thereafter receives, from the target BS, the network re-entry information and the ACK request information, and a response transmits to the target BS which indicates that it has received the network re-entry information, through the ACK channel in response to the ACK request information.

Handover system and method for minimizing service delay due to pingpong effect in a broadband wireless access communication system

In a BWA communication system, an MSS changes its connection from the serving BS to the target BS, and sends the target BS a report indicating that the MSS will change its connection upon detecting occurrence of a pingpong effect in a process of performing a network re-entry operation with the target BS. The target BS sends the serving BS a notification indicating that the MSS will change its connection. Upon receiving from the MSS a report indicating that it will change its connection to the serving BS, the serving BS allocates a contention-free-based ranging resource to the MSS so that the MSS connects a communication service with the serving BS using the contention-free-based ranging resource, minimizing a service delay.

Control of electrolysis gases in electroosmotic pump systems

Apparatus and methods according to the present invention preferably utilize electroosmotic pumps that are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. These electroosmotic pumps are preferably fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These electroosmotic pumps also preferably allow for control including venting or recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. A gas permeable membrane removes and vents electrolytic gasses generated within the fluid chamber of the electroosmotic pump to ambient. A catalyst can be used to recombine electrolytic gases to form a vapor product that can be vented or condensed into a liquid state. An osmotic membrane provides for re-entry of condensed fluid to the fluid chamber.

Method of performing handover in wireless communication system

The present invention relates to a handover method of a mobile station in a wireless communication system, and a base station and a mobile station for the same. A list of neighboring base stations that can accept a handover of a mobile station is shared by the mobile station and a serving base station before the mobile station performs the handover so as to reduce handover delay time in a high speed environment through addition, the active base station set managed by the mobile station and the serving base station can be managed with consideration of radio signal quality and resource state of each of the neighboring base stations included in the active base station set, and thus when the mobile station attempts a network re-entry process to a target base station that is not ready for the handover of the mobile station due to a loss of a handover control message, a handover failure due to a lack of radio resources can be prevented, thereby increasing a handover success rate.

Radio frequency detectable medical supplies

A medical supply such as an operating room towel, laparotomy sponge, gauze pad, bandage, or swab with radio frequency detectable material which eliminates the need for re-entry into a patent after operating in situations where medical supplies are missing. The patent can be easily scanned with a handheld scanner to determine if the medical supply was accidentally left inside the patient. If no RF detectable material is observed, unnecessary re-entry into the patient is prevented. The radio frequency detectable material is incorporated into the medical supply as a tag, in the handle, as a handle, stitched to the medical supply, woven into the medical supply, or sewn into a seam in the medical supply. An identifier on the medical supply indicates that the medical supply is an RF detectable medical supply. In addition to preventing unnecessary re-entry, scanning for RF detectable material is much safer than scanning for x-ray detectable material.
