摘要:
A method and apparatus for detecting radar signals in single and multiple (extension) channel wireless network frequencies uses spectral and DC analysis. Spectral images produced through a Fast Fourier transform may be captured and analyzed to determine if any radar signals may be present within the selected wireless network frequencies. A plurality of spectral images may also be analyzed to determine if frequency shifting radar signals are present as well. DC analysis of the power contained at the wireless carrier frequencies may detect radar signals that may be centered near those frequencies.

Techniques for estimating a cost of executing a query are provided. A query includes multiple predicates, each of which is associated with a selectivity value that indicates a percentage of input that satisfies the condition of the corresponding predicate. The selectivity values are used to determine an estimated cost of executing the query. In one technique, a group of multiple predicates of a query are treated as a single predicate. Thus, a single selectivity value, rather than multiple selectivity values, is determined for that group. In a related technique, instead of determining a selectivity value of a predicate in isolation with respect to other predicates of a query, the selectivity value of a set of one or more predicates in a query is generated based on other predicates in the query.

A unique volume license key (VLK) is provided to a volume license holder. A signed file containing the VLK and the data derived from volume license holder's submitted computing environment information is provided to the volume license holder along with the licensed software. The license file is stored in a central location, such as on an installation server, or locally on client machines, in a rather large file of any type. Upon logon, the license file is read, the data authenticated and the system is activated. If license data cannot be authenticated, a connected system either fully functions in grace period or run in reduced functionality mode until authentication succeeds. If the system is disconnected, the system is functional only with disconnected features until it joins a network again. In a completely off-line installation, the license file is generated by the volume license holder using software vendor assigned specific VLK and software vendor provided security hardware device. The distribution methods of software package, the VLK, and the license file can be flexible, including, but not limited to, single or multiple media.

The present invention relates to novel promoters, including transcription regulator regions, for the mouse VEGFR-2 receptor, isolated polynucleotides comprising such promoters, nucleic acid constructs comprising such promoters operatively linked to genes encoding a gene product, such as, a reporter, a protein, polypeptide, hormone, ribozyme, or antisense RNA, recombinant cells comprising such nucleic acid constructs, screening for therapeutic drugs using such cells (e.g., screening for compounds that modulate VEGFR-2-mediated angiogenesis), and endothelial tissue-specific gene expression using these novel promoter sequences.

A method and system for transforming and manipulating program object code. A set of program object code is transformed into a form in which it may be readily manipulated, preferably a form which is independent of both the processor and the operating system with which the object code will execute. The transformed object code is manipulated, preferably to add error-checking instructions, but possibly to add other functions or to alter the functions of the object code. The manipulated code is then reverse-transformed to program object code of the same type as the original object code.

The invention provides methods and compositions relating to a novel family of UCP3 polypeptides and related nucleic acids involved in metabolic regulation. The polypeptides may be produced recombinantly from transformed host cells from the disclosed mUCP3 encoding nucleic acids or purified from mammalian cells. The invention provides isolated mUCP3 hybridization probes, knock-out/in constructs and primers capable of specifically hybridizing with the disclosed mUCP3 genes, mUCP3-specific binding agents such as specific antibodies, animals and cells modified with the subject mUCP3 nucleic acids, and methods of making and using the subject compositions in the biopharmaceutical industry.

The present invention relates to a vehicle bumper which performs an effective function of reducing any impact forces acting on the vehicle and thus protects the safety of the passengers and the vehicle. The bumper according to the present invention comprises a base and a pneumatic cushion connected with the base and filled with gas.
摘要:
A support stand assembly having a portable table stand suitable for placing one or more holders for candles, figurine or other decorative items on its top surface. There are one or more candleholders with a permanent magnet located at the bottom of each holder. A plurality of electromagnets is fixed inside the table stand underneath the top surface. Underneath the top surface of the cake stand is one or more integrated circuit boards with circuitry for controlling the switch of magnetic poles of said electromagnets in a group and causing regulated stepping movement of the candleholders by utilizing the magnetic force between magnets in candleholders and the ones inside the table stand. It provides an all-hardware solution that does not require software programming and is easy and economical to manufacture.
