Abstract: Methods and systems for monitoring the performance of a building management system by analyzing log files of various modules of the building management system. A user request is received at a first one of the plurality of modules of the building management system, which initiates a sequence of messages processed by two or more modules. Each of the sequence of messages include a common tag value that corresponds to the user request. Each of the plurality of modules that process one of the sequence of messages logs the corresponding message including the common tag value in a corresponding log entry. The log entries are analyzed to identify resource utilization of at least some of the plurality of modules.

Abstract: A high-affinity salicylic acid-binding protein (SABP2) derivable from tobacco and Arabidopsis is disclosed. The tobacco protein has a molecular weight of approximately 25 kDa and reversibly binds SA with an apparent K.sub.d of approximately 90 nM and a B.sub.max of 10 fmol/mg protein. The SABP2 of the invention may be used to identify analogues of SA. Analogues so identified may be used in plants to augment disease-resistance response pathways or other SA-sensitive processes in which SA plays a role. Possible examples include flowering and alternative respiration. The SABP2 of the invention may also be used to identify and clone a gene or cDNA that encodes it, which then may be used to generate transgenic plants having altered SABP2 levels.

Abstract: This invention provides plant arabinogalactan proteins (AGPs) and their genes. AGPs were isolated from Nicotiana alata, Nicotiana plumbaginafolia, and Pyrus communis. Amino acid sequences of isolated AGP peptide fragments are presented. Isolated AGP fragments were used to synthesize oligonucleotide probes to prepare oligonucleotide primers for PCR or prepare RNA probes to screen cDNA libraries of N. alata, N. plumbaginafolia, and P. communis. cDNA clones encoding amino acid sequences of isolated AGP fragments were isolated. The invention presents for the first time an intact AGP amino acid sequence derived from a corresponding AGP gene. The instant invention further provides methods useful in obtaining AGP genes encoding an AGP peptide comprising a specific isolated hydroxyproline-rich (OAST-rich) sequence or a specific isolated hydroxyproline-poor sequence.

Abstract: A VCO includes a ring oscillator formed by connecting a plurality of voltage controlled inverting delay cells together, a biasing circuit for providing a bias voltage to each of the voltage controlled inverting delay cells, and a source-follower transistor for providing a control voltage to the biasing circuit and voltage controlled inverting delay cells. Each of the voltage controlled inverting delay cells includes a first and a second plurality of transistors which define two outputs of the voltage controlled inverting delay cell, and a clipper transistor connected between the two outputs to short them together whenever a difference between a bias voltage provided to a gate of the clipper transistor by the biasing circuit and a voltage on either one of the two outputs exceeds a threshold voltage of the clipper transistor.

Abstract: A VCO includes a ring oscillator formed by connecting a plurality of voltage controlled inverting delay cells together, and a plurality of transistors for providing control voltages to the plurality of voltage controlled inverting delay cells. Preferably, each transistor has a drain connected to a reference voltage, and a source connected to a voltage controlled inverting delay cell paired to that transistor. Consequently, each transistor acts as a source-follower so that it provides a control voltage to its corresponding voltage controlled inverting delay cell which follows a control voltage driving its gate, thereby isolating the control voltage provided to its corresponding voltage controlled inverting delay cell from power supply noise.
