Title: Combined simulcasting and dedicated services in a wireless communication system
Inventor: WHITEHEAD JAMES F
IPC: H04L12/56
Filed: 2001-12-14
Granted: 2005-11-01
Abstract: An efficient method for providing both dedicated and simulcast services over a common wireless infrastructure is described. The services can be available to a single terminal as well as to a multiplicity of terminals simultaneously. The method uses time division multiplexing and orthogonal frequency division multiple access for simulcasting information and transmitting dedicated message information from a plurality of base stations forming a cellular pattern over the same wireless frequency channel. The method comprises the steps of constructing frames for transmission by the plurality of base stations comprising control information, simulcast information and dedicated message information within predetermined time slots of the frames and allocating the simulcast information and the dedicated message information to time slots of the same frame predetermined by the control information of the frame. The underlying modulation technology used is OFDM and thereby the channel delay-dispersion is minimized.

Title: Extraction of integral membrane proteins
Inventor: LAKHOTIA SANJAY
IPC: C12N15/09
Filed: 2000-06-20
Granted: 2010-02-09
Abstract: A process is described for extracting gram-negative integral membrane proteins from bacteria or bacterial host cells containing a recombinant vector by differential detergent tangential flow diafiltration. This process has several advantages over alternate processes. First, it combines the clarification and extraction processes into one unit operation. The product is extracted from the cells and it is separated from cell debris with only one continuous diafiltration process. Second, the membrane proteins are extracted in a semi-purified state, which simplifies the downstream processing steps. Third, this process is very scalable because the only requirement is that the surface area of the membranes be increased proportionally with the amount of cells.

Title: System and method for surveying utility outages
Inventor: PIETROWICZ STANLEY
IPC: H04Q9/14
Filed: 2002-09-06
Granted: 2007-03-27
Abstract: Utility failures are automatically detected and potential causes for these failures are automatically located and identified without having to physically search a utility provider's network. Detection systems capable of monitoring utility status are located at each, or a subset, of the customer premises serviced by a utility provider. A monitoring system, capable of correlating the geographical location of the detection systems with the geographical location of the equipment that comprises the utility provider's network, is located at a utility provider and interconnects with the detection systems through a communications network. The monitoring system queries the detection systems to determine utility status and to subsequently locate an outage and deduce a possible cause for the outage.  Detection systems can also be configured to automatically contact the monitoring system to report utility status. The monitoring system is also capable of sending customer based information messages to the detection systems.
