Patent CA-2544800-A1 (CA)
Title: System and method for warm air space heating and electrical power generation
Inventor: GUYER ERIC C
IPC: F24D18/00
Filed: 2004-11-01
Abstract: This invention provides a system and method for cogeneration of building heat and electric power and that efficiently interfaces a warm air heating system with a liq~uid-cooled electric power generator. The system and method utilizes an electric generator that is rated at near the time-averaged electric power consumption for the build~ing. This generator is operated as the priority source of heat for the building, but nor~mally only when there is a demand for heat in building. In this manner, the generator can run to generate a significant part of the building's electric power but in a manner that is typically supplemented in variable quantities by power from a public,power grid. The heat output is directed via a liquid coolant circuit on the generator, as needed, to the warm air heating unit for the building. The warm air heating unit blows return air through a cabinet and out to the supply duct(s). The warm liquid coolant is directed through a primary heat exchanger in the cabinet. The air is passed over this primary heat exchanger to provide heat to the building. When heat from primary heat ex~ changer is insufficient to heat the building fully, an auxiliary heater, operated typically by burning fuel, supplements the heat through one or more auxiliary heat exchangers arranged in line along the airflow path with the primary heat exchanger. The blower that directs the airflow is controlled variably in speed to create the most efficient use of electric power by the blower and a desirable heated air delivery temperature.

Title: Oligonucleotide arrays to monitor gene expression and methods for making and using same
Inventor: SINACORE MARTIN S
IPC: C12Q1/68
Filed: 2005-05-11
Abstract: The present invention provides an oligonucleotide array capable of identifying genes and related pathways involved with the induction of a particular phenotype by a cell line, e.g., the genes and related pathways involved with the induction of transgene expression by the cell line. The invention is particularly useful when there is little or no information about the genome of the cell line being studied, because it provides methods for identifying consensus sequences for known and previously undiscovered genes, and for designing oligonucleotide probes to the identified consensus sequences.  Additionally, when the array is to be used to determine optimal conditions for expression of a transgene by the cell line, the invention teaches methods of including oligonucleotide probes to transgene sequences in the array. The invention also provides methods of using the array to identify genes and related pathways involved with the induction of a particular cell line phenotype. The invention also provides novel polynucleotides of undiscovered genes (i.e., a gene that had not been sequenced and/or shown to be expressed by CHO cells) and novel polynucleotides involved with the induction of a particular cell phenotype, e.g., increased survival when grown under stressful culture conditions, increased transgene expression, decreased production of an antigen, etc. These novel polynucleotides are termed novel CHO sequences and differential CHO sequences, respectively. The invention also provides genetically engineered expression vectors, host cells, and transgenic animals comprising the novel nucleic acid molecules of the invention. The invention additionally provides antisense and RNAi molecules to the nucleic acid molecules of the invention. The invention further provides methods of using the polynucleotides of the invention.

Abstract: A CDMA telecommunication system utilizes a plurality of protocol layers including a physical layer and a medium access control (MAC) layer such that the MAC layer provides data to the physical layer via plurality of transport channels (TrCHs). Each TrCH is associated with a set of logical channels. The physical layer receives blocks of data for transport such that the transport blocks (TBs) includes a MAC header and logical channel data for a selected logical channel associated with a given TrCH. Each TB has one of a selected limited. finite number of TB bit sizes. The logical channel data for each TB has a bit size evenly divisible by a selected integer N greater than three (3). The MAC header for each TB has a bit size such that the MAC header bit size plus the logical channel data bit size equals one of the TB bit sizes. A fixed MAC header bit size is associated with each logical channel for a given TrCH and is selected such that each fixed MAC  header bit size equals M modulo N where M is an integer greater than 0 and less than N, i.e. each MAC header for a given TrCH has a bit offset equal to M.
