Granted: 2013-03-26
Abstract: The terminal device has a network transceiver and a processor having a first program to cause the processor to transmit a packet of data using the network transceiver in accordance with a data transmission protocol. The first program begins transmission of a packet by sending data to a transmit signal input of the network transceiver in accordance with the protocol. At a circuit level associated with the network transceiver, a received signal in the transceiver is detected at a time of sending data to the transmit signal input. In response to this detection, transmission of the packet is prevented.

Abstract: A method and system for increasing the computational and network efficiency of presence servers having collections of publications is provided. The presence system uses several techniques that enable a presence server to provide rich presence information without requiring expensive processing. First, the presence system accepts batches of publication updates in a single presence update request. Similarly, the presence system accepts batches of subscription requests. Next, the presence system supports new expiration types for publication update requests that eliminate the need for a publishing user to continually refresh presence information that has not changed. Finally, the presence system accepts access lists that contain membership groups rather than an individual list of users that are to have access to a particular presence collection.

Granted: 2013-07-09
Abstract: A gas heat pump system powered by natural gas, propane or similar gaseous fuel is disclosed. The system uses heat recovery and heat addition to manage efficient heating and cooling cycles. In a cooling cycle excess heat is vented to the atmosphere while in a heating cycle, excess heat is used to heat a subject structure and to prevent frost from forming on outdoor heat exchangers. A control system monitors the system's operation and corrects abnormal operational conditions or shuts down the system until the system can be manually inspected. The costs of system operation are less than electric systems because of the efficiencies and use of natural gas or propane.

Title: Method for the reduction of a slag having a high degree of chromium in an electric arc furnace
Inventor: REICHEL JOHANN
IPC: C21C5/54
Filed: 2008-01-10
Granted: 2011-10-11
Abstract: During the production of stainless steel, a slag is formed during the melting of the solid material in the electric arc furnace, the slag having a high degree of metal oxides, particularly chromium oxide. The chromium concentration often reaches values of more than 30%. Currently, such slags cannot be reduced to a desired degree due to their composition. In order to minimize the resulting high loss of recyclable material, the invention provides to charge the electric arc furnace with pellets, or briquettes (8), which are made of a defined mixture of an iron carrier as the ballast material, carbon, or carbon and silicon, as the reducing agent, and a binder, wherein they react beneath the slag layer (7) in the steel melt (6) with the metal oxides of the slag (7), particularly with the chromium oxide present, in a floating, chemical, and reducing manner. The reaction gases (12) produced in the process, which are mainly made of carbon monoxide, advantageously support a foaming of the slag (7).

Abstract: Implants for repairing tissue defects, such as cartilage tissue defects, and methods of their preparation and use are disclosed. A mold of a tissue defect is prepared by pressing upon the defect a substrate having shape memory, such as aluminum foil. The mold, which has contours substantially conforming to those of the defect, is removed from the defect, and tissue particles are added to the mold ex vivo.
