Abstract: Wavelength division multiplexed optical amplifier controlling system and method are provided. The wavelength division multiplexed optical amplifier controlling system includes an optical exchange system for generating and interpreting a supervision channel optical signal, multiplexing the supervision channel and data channels comprised of a plurality of optical signals having different wavelengths, and transmitting and receiving the multiplexed channels and a plurality of optical amplifying portions located on a transmission path connected to the optical exchange system, for performing amplification so as to have even gain with respect to predetermined wavelength range which the data channel optical signals have according to the supervision channel optical signal information, and inserting the state information thereof into the supervision channel when the optical exchange system requests the state information thereof. According to the present invention, since an optical filter in each wavelength for supervision in a WDM-EDFA because a supervision channel having a predetermined wavelength is used is not necessary, the structure of the WDM-EDFAbecomes simpler. Therefore, it is possible to lower costs and there is no loss of optical signals which occurs by using a conventional optical demultiplexer.

Title: Method and apparatus for efficient operations on primary type values without static overloading
Inventor: UNGAR DAVID M
IPC: G06F9/42
Filed: 1998-08-20
Granted: 2001-06-12
Abstract: Apparatus, methods, and computer program products are disclosed for providing optimized access to pointer or externally-tagged primitive type data-values. The invention maintains a type identifier external to the variable that contains the data-value. The invention determines the type distribution of data-values stored in the variable and optimizes access to the variable accordingly. Some of these optimizations are targeted towards called routines and the call sites for the called routines. Other optimizations are targeted towards object-oriented programming language implementations. These optimizations generate optimized versions of a class/map. Objects are linked to the optimized versions of the class/map depending on the type configuration of the data-values stored in the object. Thus, the invention optimizes access to variables in the object when the object contains commonly used type configurations.

Abstract: Inhibitors of oleamide hydrolase, responsible for the hydrolysis of an endogenous sleep-inducing lipid (1, cis-9-octadecenamide) were designed and synthesized. The most potent inhibitors possess an electrophilic carbonyl group capable of reversibly forming a (thio) hemiacetal or (thin) hemiketal to mimic the transition state of a serine or cysteine protease catalyzed reaction. In particular, the tight binding .alpha.-keto ethyl ester 8 (1.4 nM) and the trifluoromethyl ketone inhibitor 12 (1.2 nM) were found to have exceptional inhibitory activity. In addition to the inhibitory activity, some of the inhibitors displayed agonist activity which resulted in the induction of sleep in laboratory animals.

Title: Acoustic communicator for central vacuum cleaners
Inventor: LINDSAY EDWARD W JR
IPC: A47L5/38
Filed: 1999-04-22
Granted: 2004-03-30
Abstract: A wireless acoustic communicator is disclosed which permits a remotely-located operator to monitor and control a central vacuum cleaner. The acoustic communicator does not need problematic batteries, airflow blockers, or special wiring networks but uses only low-frequency acoustic signals that are transmitted through the pipe system of the vacuum cleaner. Command signals are effectively transmitted, even while air is flowing through the pipe system, by using a continuous multi-frequency signal, a resonant physical structure, and an adaptive signal detector. A preferred embodiment uses a powerful reed to generate a continuous acoustic signal. The reed is manually plucked by a slide switch to start vibration, which is then continued by the airflow through the pipe system caused by the running vacuum motor. The vacuum motor runs only if the signal is present. The acoustic communicator includes a resonant detection tube that filters the signal before it reaches a microphone. The adaptive signal detector reacts to noise and airflow sensed with a microphone by tracking signal phase, altering detection criteria, and sampling independently in time, frequency, and space. In addition, the wave form of the acoustic signal can be changed to create a control signal for other central vacuum cleaner functions, such as motor speed control. The acoustic communicator can also be used to monitor the central vacuum cleaner; for example, it can report a full condition of the dust filter.

Title: Random access in a mobile telecommunications system
Inventor: ESMAILZADEH RIAZ
IPC: H04J13/00
Filed: 1998-04-24
Granted: 2010-04-13
Abstract: A method is disclosed that assigns each sector in a cell a unique preamble spreading code (106) and a unique long-code (116) which is concatenated with a signature-associated short code (112) to spread the data in the data field (120). The period selected for the long-code (116) can be relatively long in duration (e.g., up to hours or days in length). The widths of the transmission time slots are set equal to the length of the preambles (108). Consequently, the mobile station's random access requests (20, 22, 24) can be timed to start at the beginning of the slots, and detected during the preamble periods by the matched filter in the base station's random access receiver. The data field (120) of the mobile station's random access request (20, 22, 24) is transmitted in the slots following the preamble (108) and received by the rake receiver at the base station.

Abstract: A method and system for recovering from a failure of a processing node in a partitioned shared nothing database processing system are provided. The processing system may include a pair of processing nodes having twin-tailed-connected thereto a storage device. A first processing node of the pair of processing nodes has a first database instanc e running thereon which accesses a first data partition on the storage device prior to the failure. Upon detection of the failure, access t o the first data partition on the storage device is provided to a third, spare processing node through the second processing node of the pair of processing nodes. The third processing node runs a replacement database instance for the first database instance which was running on the first processing node prior to the failure thereof. The replacement database instance accesses the first data partition on the storage device through the second processing node, thereby recovering from the failure of the first processing node. Access to the first data partition may include using a virtual shared disk utility having a server portion on the second processing node and a client portion on the third processing node.

Title: Complex filtering/agc radio receiver architecture for low-if or zero-if
Inventor: BALTEANU FLORINEL
IPC: H04B1/30
Filed: 1999-11-15
Granted: 2004-07-06
Abstract: A low power IF strip architecture suitable for Zero-IF (ZIF) or low-IF (LIF) radio receivers for filtering and amplifying a received signal. The apparatus includes a plurality of sequentially connected complex filter/amplifier stages. Each stage includes a complex filter having one or more poles and an automatic gain controlled amplifier (AGC). Each AGC may be feedback or feedforward with fixed minimum and maximum gains. Each stage further includes a control circuit that produces a gain control signal for controlling the amplifier gain within the fixed minimum and maximum gains as a function of a projected amplitude level. The received signal passes through multiple stages of filtering and controlled amplification to attenuate the interfering signal and amplify the desired signal. This is done at a restricted level in each stage such that the circuits in the stages operate at efficient power saving levels. The individual gain control signals from each stage are summed in a received signal strength indicator to provide the overall gain of the apparatus. The overall gain when taken with the amplitude of the apparatus output signal determines the original strength of the desired received signal.
