Title: High resolution non-scanning spectrometer
Inventor: RANALLI ELISEO R
IPC: G01J3/28
Filed: 2001-03-02
Granted: 2003-06-21
Abstract: An optical spectrometer includes an echelle array disposed in the path of a light signal so as to diffract the incident light signal. The light signal falls within a predetermined wavelength band centered about a central wavelength. The echelle array has a plurality of diffraction scattering sites periodically spaced apart by a distance of at least about five times the central wavelength. The spectrometer further inclndes a photodetector array positioned to receive a far-field diffraction pattern produced by the diffracted light from the echelle array and to output electrical signals representing the spatial pattern and relative intensity of the far-field diffraction pattern. Additionally, the spectrometer includes a processing circuit coupled to the photodetector array for processing the electrical signals to determine the power spectrum of the light signal. The processor circuit calibrates by measuring far-field diffraction patterns and determining SIRs for light at a plurality of different known wavelengths. When the light signal is projected onto the echelle array, the processing circuit determines the power spectrum by deconvolving the SIRs obtained during calibration from the far-field diffraction pattern measured for the light signal.

Title: An arrangement for trimming an oscillator
Inventor: STEPHANSSON PAUL
IPC: H03L7/14
Filed: 2001-03-08
Granted: 2002-08-11
Abstract: An oscillator (1) is trimmed by a digital-to-analog converter (5) that receives a digital trimming signal in response to a difference between a desired frequency and a reference frequency. The oscillator (1) generates a frequency that is M times higher than the desired frequency. A divider (2) divides the oscillator frequency by M to provide the desired frequency. A splitter (4) splits the digital trimming signal into a digital coarse trimming signal, and a digital fine trimming signal. The converter (5) converts the digital coarse trimming signal into an analog coarse trimming signal. A comparator (6) receives the digital fine trimming signal, compares it with a counter signal received from a counter (7) repeatedly counting M periods of the oscillator output signal, and generates an output signal until the value of the digital fine trimming signal and the counter signal are equal. The converter (5) receives said comparator output signal and converts it into an analog fine trimming signal that is added to said analog coarse trimming signal to control the oscillator (1).

Title: Two-staged ESD protection circuit with accelerated conduction of the secondary stage
Inventor: LIN GEENG-LIH
IPC: H01L27/02
Filed: 2001-04-24
Granted: 2002-05-21
Abstract: A kind of two-staged ESD protection circuit for input/output port is disclosed in the present invention. The two-staged ESD protection circuit is coupled between an input/output bonding pad and a power source line, and includes a primary ESD protection device, an ESD detection circuit, a serially connected resistor and a secondary ESD protection device. The primary ESD protection device and the ESD detection circuit are coupled between an input/output bonding pad and a power source line. The serially connected resistor is coupled between the bonding pad and an interior circuit. The secondary ESD protection device is an NMOS transistor and is coupled between the inner circuit and the power source line. When an ESD case occurs, the ESD detection circuit provides a control signal for one gate of the NMOS transistor of the secondary ESD protection device such that the secondary ESD protection device starts up even earlier than the primary ESD protection device to clamp ESD voltage and effectively protect the inner circuit. The secondary ESD protection circuit can be a native NMOS transistor. The advantage of the present invention is that the starting up time between the primary and the secondary ESD protection devices can be appropriately separated. By controlling the sending time of the control signal from an ESD detection circuit, the starting up speed of the secondary ESD protection device can be accelerated so as to obtain the purpose of raising ESD protection capability and provide more protection for the inner circuit.

Title: Buffer management for support of quality-of-service guarantees and data flow control in data switching
Inventor: WANG LINGHSIAO
IPC: H04L12/54
Filed: 2001-09-24
Granted: 2003-03-01
Abstract: A method of utilizing shared memory resources in switching protocol data units (PDUs) at a data switching node is presented. The method includes reserving: a temporary memory storage portion for storing PDUs prior to queuing for processing thereof, a class-of-service memory storage portion to provide support quality-of-service guarantees, a shared memory-pool portion and an input port memory storage portion enabling non-blocking input port flow control. Provisions are made for PDU discard decisions to be delayed until after PDU headers are inspected subsequent to the receipt of each PDU. Provisions are made for well-behaved data flows conveyed via an input port to be protected against blocking from misbehaving data flows conveyed via other input ports of the data switching node. The advantages are derived from a memory management scheme which can be equally applied in a PDU discard and a flow control environment to reduce PDU discard instances at a data network node implementing the memory management scheme while reducing memory storage requirements.
